3.23.40 overload
Hello Time to time I see strange overload of MySQL on dedicated server. The server is powerful enough to handle ~ 500 req/s. MySQL version is 3.23.40 and runs on Linux 2.4.16-SMP. The overload which I mean leds to stop answering to queries and looks like: 6:24pm up 6 days, 2:34, 2 users, load average: 164.18, 91.07, 39.56 270 processes: 73 sleeping, 197 running, 0 zombie, 0 stopped CPU0 states: 99.23% user, 0.15% system, 0.0% nice, 0.1% idle CPU1 states: 97.17% user, 2.21% system, 0.0% nice, 0.0% idle Mem: 513504K av, 50K used, 13504K free, 0K shrd, 22892K buff Swap: 1036184K av,7540K used, 1028644K free 305928K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 30453 mysql 14 0 19204 18M 2224 R 6.9 3.7 0:02 mysqld 30454 mysql 14 0 19204 18M 2224 R 6.9 3.7 0:02 mysqld [skip] 30460 mysql 16 0 19204 18M 2224 R 6.9 3.7 0:02 mysqld On the other hand I see Slow_launch_threads counter equal to 2 that means there were a problem with thread create (took more then 2 sec). Others thread-related counters: Threads_cached 59 Threads_created 68 Threads_connected 2 Threads_running 1 So what seems to be a source of the problem - linux kernel, MySQL 3.23.40 or wrong tunning ?

console freezes when starting mysqld
I am running two different servers, one with the tarball distro and the other with an rpm. Both are on Redhat 7.1. Upon executing mysql.server or safe_mysqld the console executes the command but does not return to a prompt. I can change to another console and see the server started ok. I can log on etc. However, it locks the console I execute it on every time. This causes a problem when booting, as I run these commands from rc.local and it stops the boot process there. Using the built in script from the rpm that gets installed into init.d is not an option in these particular cases (long story) so I'm hoping to find out what I can do to get the prompt back. Larry S.

Fwd: RE: Optimization
Hi! I just forwarder your email about query caching (Yes, I know that the query cache in MySQL 4.0 has solved this for you but...) Hello all, I'm having real trouble trying to optimize MySQL cause I can't believe that MSSQL is faster. My configurations are as follows: MSSQL 2000 on W2K server. PIII 733 - 512 MB memory. MySQL-3.23.47-1 on Redhat 7.2. Dual PIII 1000 - 1.128 GB memory I have a PHP script that runs on a Redhat 7.1 - PIII 500 640 MB memory. The php script takes a username from a mysql table and runs a query for each of the usernames on another table. The test is that I have 2 different versions of the script that do the exactly same thing but one queries the MSSQL server and the other the MySQL. The MSSQL version takes 28 secs while the MySQL takes 34 secs. As you can see the MSSQL is much more slower with less RAM. I said what the heck I will use the my-huge.cnf to see if it makes any difference. Unfortunately nothing changed and then I started panicking.. It can't be true! I noticed that MSSQL caches the queries while MySQL doesn't. In my script I might have this: select emails from dbo_Company where username=''; come up 5 or even 10 times. If I run it on mysql It takes always 0.26 secs while it appears the MSSQL caches the result and doesn't take any time at all. Any chance you could give us a copy of the dbo_Company table to use for testing ? (If yes, please upload the .frm, .MYI and .MYD files to: ftp://support.mysql.com/pub/mysql/secret) According to tests I have done, for a simple query as the above, MySQL should usually be faster than MSSQL, even with MS-SQL query caching. (Look at: http://www.mysql.com/information/benchmark-results/result-db2,informix,ms-sql,mysql,solid,sybase-relative.html and the test for select_key, where MySQL is 3.52 times faster on simple key lookups) A couple of reasons for your results: - username is a primary key or the table is sorted according to the user name (explicite or implicit) in MS-SQL. - The query returns many rows, and they rows are far apart in the data file, so MySQL has to do many reads to fetch the rows. (In this case it's the file caching in Windows that is slow). In both cases, an OPTIMIZE TABLE or 'ALTER TABLE dbo_Company ORDER BY username' would speed up things considerably in MySQL. If the reason for the speed difference is that 'username' is a primary key and MS-SQL stores the row clustered together with the primary key, then by using the InnoDB table handler you should get the same benefit in MySQL as MS-SQL has. (The downside with this algorithm is that secondary keys are slower, but that is another issue) For example, MyISAM stores the rows separate from the keys. This makes the primary key slightly slower in MyISAM (except when you only want to have information from the primary key, then MyISAM should be faster), but instead all keys are equally fast and table scans are much faster. No sql server can be faster an ALL queries; Depending on the optimization engine and how rows are stored you get certain benefits but also some downsides. If MS-SQL is faster in this case, we would like to add a similar case to the MySQL benchmark suite because: - If MS-SQL is faster on this particular case, we want to acknowledge this fact (give credit where credit is due...) - We would like to know why MS-SQL is faster so that we can document this and provide workarounds - We will know about this and can in the future try to speed up MySQL for this case. - We will do the test with all the table handlers MySQL support; This will show if the speed of this test is dependent of how the rows are stored or by the optimizer. Thanks for any help you can give us regarding this!

Checking if Replication really works
Hy, having Replication running now, I would like to know if there are ways to test if it all _really_ works ok. Things i know I could do: - checking that no errors occur in the logs on master and slave - testing some queries an see if the changes take effect on the master and the slave in the same manner - maybe testing the size of the database directories on the master and the slave (after doing the right flush commands and shuttong dowen master?!) or doing diffs of all the files in the databse directories - counting the number of rows in each table Can I use those all to check if everythings ok? Are there other testing mechanisms? Or can i just trust in Mysql that everything that _can_ go wrong will produce error messages? Another interesting question would be if i can configure mysql to send an email when an error occurs, or if i have to use third party software to watch the logs?

Two daemons, 1 data dir.
Hi, I've got 2 mysql server that I want to configure in a hot-standby config in the following manner: Two servers with a fibre channel connection to a central storage array. The data dir of the database is on this storage array. The OS (linux or solaris, haven't decided yet) sees this datadir as a normal part of its filesystem. The two servers are both connected to a layer 7 switch that can do loadbalancing and hotstandby switching. I'd like to configure the switch to do the last. The switch makes use of a virtual IP address an to this VIP a pool of real addresses is asigned. The switch is configured to 'route' all traffic on port 3306 via a primary path. In case of failure in this path (for instance by crashing of the mysqld) the switch wil start using the secondary path. This setup is completely transparant for the mysql client, because the client is communicating with the VIP of the switch. I'd like to use this setup because a master/slave config is too slow in case of failover for our situation (we need a very fast failover config). Now I'd like to know the following: Can two mysqld's use the same datadir/database (remember they are not writing to the same database at the same time!)? Which OS will support this best in terms of filelocking etc. Linux or Solaris (the fibre channel adapters are well supported in both OSes). Any other views on this type of setup.

But I got in throuble with this idea because after a mass update of records the subsequent diff used all memory an swap space. I think the size of the files should be less than the total RAM if you want to be sure that it will always work with the standard unix diff utility Rune - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

RE: Two daemons, 1 data dir.
Yes you can run two or more MySQLD's for one database. You seem to know the problems with this.. I would use Linux but I just find it easy to use mysqld is stable but if it is not you could just kill it and restart a new one. What is more important is the data, how are you protecting that? If mysqld if faulty it mite just damage the data?

Re: Error 1114 table full with 14000 error??
Hi!
You have hit the problem of easy installation of MySQL-4.0 :)
From the manual at http://www.innodb.com/ibman.html :
.
2 InnoDB startup options
To use InnoDB tables in MySQL-Max-3.23 you MUST specify configuration
parameters in the [mysqld] section of the configuration file my.cnf, or on
Windows optionally in my.ini.
At the minimum in 3.23 you must specify innodb_data_file_path. In MySQL-4.0
you do not need to specify even innodb_data_file_path: the default for it is
to create a 64 MB file ibdata1 to the datadir of MySQL.
But to get good performance you MUST explicitly set the InnoDB parameters
listed below in the examples.
MySQL-4.0 automatically creates a 64 MB data file ibdata1 if you do not
specify any InnoDB startup options. When that file gets full, you will get
the 'table is full error'.
Please look in the manual and specify the InnoDB options in my.cnf as
recommended.
Best regards,

I have been able thus far to successfully import at

compiling and/or running 64-bit MySQL on Solaris 8/sparc?
Is it possible to compile and run MySQL as a 64-bit program on Solaris 8?
If so, are there precompiled bits available?
The primary reason for doing this is to determine if a 64-bit version would
allow the database to be larger than 4-gig. I have been told by another
member of our team MySQL has such a limit, and he suggested a 64-bit build
might overcome it. Is this correct?
I've been attempting to compile MySQL 3.23.47 and 4.0.1 as a 64-bit program
using gcc 3.0.3. To build the GCC 3.0.3 with 64 bit capabilities I believe
I followed the example found here faithfully:
http://www.well.com/~jax/rcfb/solaris_tips/build_gcc_3.0_64bit.html
http://www.well.com/~jax/rcfb/solaris_tips/build_gcc_3.0_64bit.html
When I attempt to build the MySQL I get an argument from the ./configure
script telling me checking return type of sprintf... configure: error: can
not run test program while cross compiling. I'm not an expert in the area
of gcc and the gnu tools, so I may well have done something wrong somewhere
along the line. I'd like to know if I am attempting something that can be
accomplished. Has anybody got this working?

Re: Porting from MS SQL to MySQL
Hi first of all it is ridiculus of the company to offer something other than your specifications. if they want to offer you a solution other than what you need, they have to change the software at their cost not at yours. in my opinion it is better to not accept this solution at all and look for other options. you will definitely get lots of options. for starters go thru freshmeat.net.

Re: Porting from MS SQL to MySQL
If you know you're going to port it, it really shouldn't be too difficult. In fact, if you're creating it with the intention of porting it, you can (and should) use MSSQL datatypes that are compatible with MySQL. If you do this, porting is a trivial task at best. 18,000 euro seems a bit steep for a couple hours of work... By-the-way: there doesn't seem to be any obvious reason to create the database in MSSQL (other than a 18,000 euro conversion project later). You might consider developing the database using MySQL or PostgreSQL initially and eliminate the conversion issue...

replication between two databases on single server?
Is it possible to replicate between two databases on a single server, and if not, then what is the next best solution? I administer a Bugzilla installation with about 1.8GB in a MySQL database. Bugzilla has a built-in replication solution that copies data from a primary database optimized for updates to a shadow database optimized for reads. This replication solution has a few hard-to-find bugs that cause periodic data corruption in the shadow database. We work around these problems by recreating the shadow database from scratch every night, but that causes its own problems with disk space availability (for the dump file) and downtime (it takes up to an hour without compression and up to 1.5 hours with gzip compression to dump the data into a dump file and then import it into the shadow database, and night for the bulk of our users is day for our other users around the world). So, I'm looking for a better solution. It's possible that I could obtain a second server and hack Bugzilla to handle it, but first I want to find an easier solution if one exists. Is there a way to use MySQL's built-in replication to replicate two databases residing on the same server? If not, is there another replication solution that could do the job? If not, could mysqlhotcopy solve my problems with the nightly shadow database rebuild at least, and if so do I need to do anything more (i.e. lock that database) than point the script at the shadow database directory and let it overwrite those files? -myk - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

RE: Porting from MS SQL to MySQL
I can't say that I am a database specialist, but I still think that there will be some problems porting a MSSQL to mysql, and this because it seems that MSSQL is very linked to the operating systems it runs on, i.e. Windows (only think to the security for MSSQL). -Original Message- From: Markus Lervik [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 3:06 PM To: [EMAIL PROTECTED] Subject: Re: Porting from MS SQL to MySQL On Friday 18 January 2002 15:58, you wrote: On Fri, Jan 18, 2002 at 03:16:15PM +0200, Markus Lervik wrote: We've requested a database from different companies, and specifically said we wanted MySQL or PostgreSQL because of the open source angle and we're a library.

RE: Two daemons, 1 data dir.
My concern would be, what is the mysqld without a database going to do. Wouldn't it need some kind of dummy data dir. I'm sure the daemon does some random checks of its data to ensure that it is still there. If this is not a problem then this seems fine. As far as the OS goes, I would like to suggest Linux, but I would think that the file locking is better in SOlaris. Hope this is helpful. John Lodge -Original Message- From: CyberSushi [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 11:39 AM To: mysql Subject: Two daemons, 1 data dir. Hi, I've got 2 mysql server that I want to configure in a hot-standby config in the following manner: Two servers with a fibre channel connection to a central storage array. The data dir of the database is on this storage array. The OS (linux or solaris, haven't decided yet) sees this datadir as a normal part of its filesystem. The two servers are both connected to a layer 7 switch that can do loadbalancing and hotstandby switching. I'd like to configure the switch to do the last. The switch makes use of a virtual IP address an to this VIP a pool of real addresses is asigned. The switch is configured to 'route' all traffic on port 3306 via a primary path. In case of failure in this path (for instance by crashing of the mysqld) the switch wil start using the secondary path. This setup is completely transparant for the mysql client, because the client is communicating with the VIP of the switch. I'd like to use this setup because a master/slave config is too slow in case of failover for our situation (we need a very fast failover config). Now I'd like to know the following: Can two mysqld's use the same datadir/database (remember they are not writing to the same database at the same time!)? Which OS will support this best in terms of filelocking etc. Linux or Solaris (the fibre channel adapters are well supported in both OSes). Any other views on this type of setup.

I understand it has to re-iterate if the number of rows in the result without DISTINCT is greater than the limit clause, but if the result without DISTINCT is lower, it should be faster to perform the DISTINCT on the result directly (or perhaps I'm missing something ? ;)). - Original Message - From: Sinisa Milivojevic [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Friday, January 18, 2002 4:27 PM Subject: Re: Why does DISTINCT take so long time ??

I'm not sure I'm understaidning your question completely, but I'll try to answer it anyway. 1) Porting from MS SQL to MySQL is not the easiest of things. There are several options, and they include connecting to both via MS Access and ODBC, or using the Sybase perl drivers with the FreeTDS library to get it to talk to MS SQL. They you can write a program in perl to port the data. 2) If you want MySQL or PostgreSQL, why exactly would you want to install MSSQL, and then upgrade later? Both PostgreSQL and MySQL will run on Windows (although again, I'm not sure why you would want to do that if you have a choice). All in all, it can be complicated and time consuming. You don't want to go there. Just get MySQL or PostgreSQL in the first place, and save yourself the trouble of porting the data later. If you are about to implement a system from scratch, it's is always easiest and cheapest to do it right in the first place, with the software you want. Regards.

Memory limit issue with mysql.3.23.41
We are running an extremely large instance of mysql version 3.23.41 on Solaris 2.8 and have been experiencing memory related server crashes. The behavior suggests that we are running out of memory / swap, but we have over 2 gig of memory and 10 gig of swap free. Our server settings are: key_buffer=5120M max_allowed_packet=1M table_cache=1024 sort_buffer=6M record_buffer=4M thread_cache=12 thread_concurrency=12 myisam_sort_buffer_size=512M The server tends to crash upon reaching a total memory usage of around 4 GB Here is the output from the error log. Of particular interest to us is the negative key_buffer_size quoted. The same value (-4096) appears with each crash. Is there some sort of memory limit imposed on the server or do you have suggestions for debugging this problem? Thank you, Kevin Franklin 020117 18:19:58 Out of memory; Check if mysqld or some other process uses all available memory. If not you may have to use 'ulimit' to allow mysqld to use more memory or you can add more swap space 020117 18:19:58 Out of memory; Check if mysqld or some other process uses all available memory. If not you may have to use 'ulimit' to allow mysqld to use more memory or you can add more swap space mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked agaist is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail key_buffer_size=-4096 record_buffer=4190208 sort_buffer=6291448 max_used_connections=308 max_connections=1024 threads_connected=309 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 2093044 K bytes of memory Hope that's ok, if not, decrease some variables in the equation 020117 18:19:58 Out of memory; Check if mysqld or some other process uses all available memory.

Re: Porting from MS SQL to MySQL
Porting a DB takes more 'than a couple of hours'. What about the written procedures, the security mappings, the back up and recovery procs, the fallback arrangements, the testing etc. Yes, porting a database that was written for MSSQL with no intention of porting can be a painful proposition. However, if you have control over how the system is developed, you can easily design the system to be compatible with EITHER MSSQL or MySQL (the differeces are well-documented). If you develop your system with porting in mind (ie the original post of they'll develop in SQLServer and port it to MySQL later) porting should not take more than a couple of hours. You simply choose appropriate datatypes and don't use MSSQL-specific extensions...

DBGRID displays only (MEMO)
Hallo, I am developing a database application using Kylix ver.1 and MySQL 4.23.41-log . I can connect and execute the query but the problem is my DBGRID only displays (MEMO) . Some of my friends said that perhaps it is caused by the datatype of the field but I tried to change the datatype of the field from ftmemo into ftstring over fielddefs but.. once I restarted the database connection... the datatype of my field is automatically changed back into ftmemo and again my DBGRID doesn't display the queried table but only diplay (MEMO) in each of its cells. Is it because I have determined a wrong datatype on my MySQL ? I am using text and longtext datatype for the troubled queried table on my MySQL. So which datatype of the field do I have to use to make my DATAGRID can display my table properly ? Thank you very much for your help. __ Do You Yahoo!? Send FREE video emails in Yahoo!

RE: Porting from MS SQL to MySQL
I agree. I have more experience with MS SQL than mySQL, but there are some MS SQL specifics that can cause hiccups. But these hiccups can be avoided with a bullet proof project plan and excellent documentation. You may not be able to automate all the project procedures and a lot of the database re-construction, which is OK. Make sure you run a test system to see if the migration is successful. Migrations are my specialty! Good luck, and don't be afraid to ask questions on the migration! -Original Message- From: j.urban [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 10:08 AM To: Tony Buckley Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Porting from MS SQL to MySQL Porting a DB takes more 'than a couple of hours'.

You simply choose appropriate datatypes and don't use MSSQL-specific extensions... I still don't agree with this. Yes you can ease the passage by considering all the issues up front but it is still not a trivial job for a database of any consequence. There is more to a database than a physical schema - what about all the administration procedures that sit around it, what about tuning the new physical implementation, what about reviewing the access paths and optimisation, what about the redevelopment of data loading scripts. As I have said in another post, it's futile arguing about it because we don't know enough about the technical situation let the business/political one. Are you seriously saying you could sit down in front a reasonably sized DB you had never seen before and understand all the business issues and pick it up and ship to a new RDBMS and platform, rewrite the document, replan what I have stated above, and get it back up and running in two hours? Perhaps I am getting too old and slow but it would take me longer :-) I am not saying it's a huge task to do any of this but whoever said, I could do it in a couple of hours, doesn't understand the background that led to a company quoting E18k; nor do any of us, and for anything other than a very very trivial system, two hours seems inadequate. This is an area that interests me, because I directly bid for work such as this, and when tendering you usually find the bloke down the road working out of his spare bedroom that thinks he can do it for a tenner over one day. The company requesting the work then thinks that everyone else is overinflating their prices so goes cheap and pays for it big time downstream. Cheapest and quickest is rarely best. On the flip side, nor is most expensive. Tricky world init.

RE: Porting from MS SQL to MySQL
I wasn't talking about migration of a 30gb DB2 system. I was talking about porting a system that was specifically designed to be ported. If you design it correctly up front, you can port it very painlessly. You can easily develop a system that uses the proper datatypes and does NOT use MSSQL-specific extensions. This type of system can easily be ported. Porting a legacy application that someone else developed is likely to be a duanting task, I agree. But I'm talking about a system that has not been developed and can be designed with porting in mind. I just finished a system that was developed 100% for MySQL. It was ported to work with MSSQL and now works with either. There was exactly ONE column change and the actual porting of the database and the back-end code was 2 hours max. This is because there is almost nothing to do provided you've designed the system with porting in mind... You've seen some OLAP developers take 3 months to complete a migration, and I've seen (at least one) company take over 6 months to convert a Paradox system to MSSQL. Neither example is relevant to the current discussion. An MSSQL system can be designed and developed with porting in mind and porting can be painless.

So basically, if you already own Mascon (or buy it from http://www.scibit.com/ for $49.00), and download the latest installable binary releases of MySQL, Apache, etc, you've got the MySQL Studio, and as a bonus, it features a clean, standard UI, with the standard Windows style widgets. Ah, this is good to know. I wasn't interested in the binary installers or the Apache/MySQL since I build those myself. But I keep hoping for an enterprise level tool that works with MySQL.

Re: Memory limit issue with mysql.3.23.41
If you only have 2GB of RAM and you are allocating 5120M (=5GB) for the key_buffer, you have a problem. That should make your system swap like mad and everything slow to a crawl. Also, note that some of these config options may effect per-thread allocation. I don't know which ones off the top of my head, but I think the manual makes it clear. Things to remember: MySQL stores index data in the key_buffer. It does not store data there. MySQL does not cache data. If you tell it to allocate more memory than the system has, you'll use up all memory for the index, allocate swap for it (really slow), and leave no space for the OS to cache data. We usually allocate between 30 and 50% of the available DRAM for the index and leave the remaining things much smaller. This lets the OS do some caching on its own. If you take all the memory for the indexes of MySQL, I am amazed that it was able to run with any speed at all. What it looks like is that you allocated your 2G of memory and then wandered quickly into the weeds. Swap != RAM.

Re: Memory limit issue with mysql.3.23.41
Kevin, The Mysql documentation suggests you use no more than 75% or 80% of physical memory to allocate for key_buffer. As Heikki and Jeremy confirmed for me this week, sort_buffer and record_buffer are the ones that grow per thread - Heikki suggested 1Mb for each of those. Using swap as RAM (as Kyle suggests) is not a good idea for any process, as it will certainly slow your system.

Note that the math seems to be wrong too since you set record_buffer to 4M and sort_buffer to 6M, you should be allocating 10M per thread. That's a lot of RAM for a system with only 2G. Hope that's ok, if not, decrease some variables in the equation I think it has the right idea here.

ostream, C, C++
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I have a problem compiling an app that uses the MySQL C API. My program itself is C++ using Visual C++ 6.0 in Windows 2000, but the C api is plenty sufficient for me. I suspect the problem comes because when I include C++ streams, I use the ANSI C++ standard way of doing so: #include iostream (and then I import the std namespace) rather than the deprecated way of doing so: #include iostream.h When I include the C api by doing: #include config-win.h #include mysql.h I get a slew of errors. For the life of me, I cannot figure out how to fix them (I must be sleepy and/or hungry). Can someone help me out? I tried searching the mailing lists but I couldn't find anything.

RE: host = %
Hi ppl, When I set database and user host to % I can't connect to database when using localhost - authorization fails. When I connect using domain name, every things works fine. Q1: What is the problem using localhost? No problem - just a different type of connection. When you specify localhost, you're also saying accept connections through a socket. When you say % or some derivation thereof, you're telling the server to accept connections through TCP/IP. Q2: How can I set default localhost to domain name? I don't believe you can - not for the server, at any rate. For the client, you can twiddle values in my.cnf to suit your needs. / Carsten -- Carsten H.

Full Text Search with and without index - possible bug?
Hi.
I thought it would be useful to share my findings. They all relate to the
4.0.1 release. It would be nice to have some clarification on whether this is
expected behaviour, whether this behaviour is wrong (i.e. bug, corrupted
index, etc), and what you guys think could be causing it.
1.1) Full Text Search can, according to the manual, be performed without the
FTS index, but it is slower.
1.2) MySQL can only use 1 index per join per table.
= This means that if I specify the USE INDEX (some_non_fulltext_index), the
FTS will be performed without the index, and this will only work IN BOOLEAN
MODE. Otherwise, MySQL returns an error, complaining about the lack of an
index.
HOWEVER, please someone explain why the following results are happening:
Two nearly identical queries, similar to:
SELECT Table1.ID,
Table1.Title,
Table1.Type,
Table1.Description,
DATE_FORMAT(Retrieved, '%d-%b-%Y %H:%i:%S') AS Retrieved
FROMTable1
WHERE Type = 'SomeType'
AND Retrieved '2002011800'
MATCH (Title, Description) AGAINST ('some words to match' IN
BOOLEAN MODE)
ORDER BY MATCH (Title, Description) AGAINST ('some words to match' IN
BOOLEAN MODE) DESC;
and
SELECT Table1.ID,
Table1.Title,
Table1.Type,
Table1.Description,
DATE_FORMAT(Retrieved, '%d-%b-%Y %H:%i:%S') AS Retrieved
FROMTable1 USE INDEX (Table1_Retrieved_Index)
WHERE Type = 'SomeType'
AND Retrieved '2002011800'
MATCH (Title, Description) AGAINST ('some words to match' IN
BOOLEAN MODE)
ORDER BY Retrieved DESC;
These two queries return DIFFERENT numbers of records!
If my understanding of the documentation is correct, the second example
should be slower because the FTS index isn't used. But the results should be
the same right? Well, that definitely isn't the case in my database.
I have just done a REPAIR TABLE Table1, Table2... EXTENDED, so the tables
definitely aren't corrupted.
The FTS index search returns 24 records on my data set (~ 60K records), and
the non-fts search returns 7 records.
The reason I have been even trying this is because FTS is a bit slow for some
of the things I am doing. By limiting the data set through the Retrieved
date field, I can usually cut the data down to about 10% of the total size,
hoping that non-indexed FTS on that will be faster.
Well, it turned out to be faster for cases where the data set was cut down a
lot by the index, but the IN BOOLEAN MODE FTS doesn't seem to be reacting to
things like '-word' in the MATCH/AGAINST clause, as it should per the FTS
search. Sometimes, specifying a '-word' that should only remove a few results
returns 0 rows - which is clearly wrong in some cases.
Is there a know bug in the indexless FTS that causes this? The indexed FTS is
behaving well, but I was really hoping to gain some speed by using a
different index in some specific cases...
Regards.
Gordan

RE: Tergat MySQL Studio
Unfortunately Mascon doesn't have any ER diagramming tools for schema modeling. I bought Heraut Solutions' Dezign for Databases for this purpose a while back, but its somewhat clunky, unprofessional look/feel has been a bit of a turn off. I've enjoyed using Sybase' Powerdesigner for this purpose, it works pretty well. I only wish it supported MySQL in a more integrated, native fashion. I haven't had the pleasure of using Erwin, but I understand it's a good tool. Any other recommendations for ER modeling? -Original Message- From: Chris Lott [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 12:39 PM To: MySQL List (E-mail) Subject: RE: Tergat MySQL Studio So basically, if you already own Mascon (or buy it from http://www.scibit.com/ for $49.00), and download the latest installable binary releases of MySQL, Apache, etc, you've got the MySQL Studio, and as a bonus, it features a clean, standard UI, with the standard Windows style widgets.

In the opinion of those who know, which system would best serve our needs? The four slower processors, or the two faster processors? Why? From the user manual: 9.3.1 MySQL Threads The MySQL server creates the following threads: * The TCP/IP connection thread handles all connection requests and creates a new dedicated thread to handle the authentication and and SQL query processing for each connection. * On Windows NT there is a named pipe handler thread that does the same work as the TCP/IP connection thread on named pipe connect requests. * The signal thread handles all signals. This thread also normally handles alarms and calls process_alarm() to force timeouts on connections that have been idle too long. * If mysqld is compiled with -DUSE_ALARM_THREAD, a dedicated thread that handles alarms is created. This is only used on some systems where there are problems with sigwait() or if one wants to use the thr_alarm() code in ones application without a dedicated signal handling thread. * If one uses the --flush_time=# option, a dedicated thread is created to flush all tables at the given interval. * Every connection has its own thread. * Every different table on which one uses INSERT DELAYED gets its own thread. * If you use --master-host, a slave replication thread will be started to read and apply updates from the master. mysqladmin processlist only shows the connection, INSERT DELAYED, and replication threads. As you are looking at having only one connection, I would say it is likely that 2 1.4 Ghz CPUs will give you better results than 4 900 Mhz CPUs, all other things being equal. Also, remember that operating systems don't scale linearly in the best of cases, though Linux scales well up to 4 CPUs. Someone more knowledgable than I will speak up, I'm sure, but I'd focus on dual CPUs with more memory rather than going for a 4 CPU machine. Also, high speed disks would be nice, too. In fact, I'd say more likely you'll see more performance with ONE CPU with more memory and faster drives than you would with a 4 CPU machine limited in RAM and hard drive speed. -BEGIN PGP SIGNATURE- Version: PGP Personal Security 7.0.3 iQA/AwUBPEiLrgAttZAy2w6WEQIYKgCghq00GE1/2TXOguN6FkxacH9gumMAn0Vi eUcuISI6S/W/h0KtvDeAliuy =gmoV -END PGP SIGNATURE- - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Database locks up on certain queries. Is this intentional ?
Hello, I'm experincing a problem with my database locking up on some queries. Any explanation or solutions anyone can provide will be much appreicated. - ##Scenario: 3 tables: company, co_type_assoc, co_type ##with data pertaining to [co_id in (0,1) as follows] mysql select * from co_type; ++--+--+--+ | co_type_id | co_super_type_id | code | description | ++--+--+--+ | 1 |4 | AC | Associate Consultant | | 2 |4 | AL | Associate Life Member| | 3 |4 | AM | Associate Media | ++--+--+--+ 3 rows in set (0.00 sec) mysql select * from company where co_id = 0; Empty set (0.00 sec) mysql select * from company where co_id = 1; +---+---+---+---+---+-++ | co_id | name1 | name2 | sort_name | email | website | pri_co_type_id | +---+---+---+---+---+-++ | 1 | SHOPA | | | | | 1 | +---+---+---+---+---+-++ 1 row in set (0.00 sec) mysql select * from co_type_assoc where co_id in (0,1); Empty set (0.00 sec) - ##When I run the following query, there is no problem: mysql Select cta.co_type_id , ct.description from company c, co_type_assoc cta, co_type ct where c.co_id = cta.co_id and ct.co_type_id = cta.co_type_id and c.co_id = 1; - ##But if I run this query, the entire database locks up: mysql Select cta.co_type_id , ct.description - from company c, co_type_assoc cta, co_type ct - where c.co_id = cta.co_id - and ct.co_type_id = cta.co_type_id - and c.co_id = 0; ERROR 1015: Can't lock file (errno: -30989) - On examing the queries using EXPLAIN, I get the following: - mysql explain - Select cta.co_type_id , ct.description - from company c, co_type_assoc cta, co_type ct - where c.co_id = cta.co_id - and ct.co_type_id = cta.co_type_id - and c.co_id = 0; +-+ | Comment | +-+ | Impossible WHERE noticed after reading const tables | +-+ - mysql explain - Select cta.co_type_id , ct.description - from company c, co_type_assoc cta, co_type ct - where c.co_id = cta.co_id - and ct.co_type_id = cta.co_type_id - and c.co_id = 1; +---++---+-+-++- -+-+ | table | type | possible_keys | key | key_len | ref| rows | Extra | +---++---+-+-++- -+-+ | c | const | PRIMARY | PRIMARY | 4 | const |1 | | | cta | ref| PRIMARY | PRIMARY | 4 | const |1 | where used; Using index | | ct| eq_ref | PRIMARY | PRIMARY | 1 | cta.co_type_id |1 | | +---++---+-+-++- -+-+ 3 rows in set (0.00 sec) - So my question is 1) Why does the database lock up ? 2) Is this intentional, i.e. the optimizer is smarter than I want. 3) How can I overcome this problem ? Any help anyone can provide will be very much appreciated. Thank you.

RE: Column Alias Bug??
count(*) works if I do not alias it with z, and do not use WHERE clause: mysql select a,count(*) from aa group by a; +--+--+ | a| count(*) | +--+--+ |1 |2 | |2 |2 | |3 |2 | |4 |1 | |5 |1 | |6 |1 | +--+--+ 6 rows in set (0.40 sec) -Original Message- From: Nathan [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 3:34 PM To: Rick Emery Subject: Re: Column Alias Bug?? What does the count(*) do? If that's failing, maybe the alias doesn't get created? Shot in the dark obviously... :-) # Nathan - Original Message - From: Rick Emery [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, January 18, 2002 2:30 PM Subject: Column Alias Bug??
