Re: RSA encrypted strings - what data type?
Well, I screwed around with it. This is what I got ( just in case anybody cares.. ) ( this is in perl, using the Crypt::RSA module.. ) $password = screwyou!; # encrypts the 'password'... $cyphertext = $rsa-encrypt(Message=$password, Key=$pub); # now convert the RSA encrypted key to binary. $bin_str = unpack(B*, pack(u*, $cyphertext)); # now reconvert it back to uuencode.. $recypher = unpack(u*,pack(B*, $bin_str)); # then decrypt it. $plaintext = $rsa-decrypt(Cyphertext=$recypher, Key=$priv); # prints screwyou! print $plaintext\n; Mysql has no trouble keeping the binary version.

MySQL oddity
Below is a table declaration in a database I just created. The oddity is the 2 fields, CL_FIRST_TS and CL_LAST_TS, are automatically marked as Required in the table's Validity Checks listing. This means that I have to add a value to both of them each time I insert a new record. They are involved in a legacy issue by old input devices or I would remove them. Nothing I do will change this behavior. Can anybody please explain to me why they are the only ones in the whole database to do this? The database consists of 90 tables with this one being number 9. I have tried this under MySQL v3.23 and v4.01 and get the same results.

RE: GRANT
If I understand correctly, you can achieve your goal in either of 2 ways. The first, is to copy sql.exe to one of your path directories (i.e. Windows or Windows\System) or include MySQL\bin in your DOS path statement. This will allow you to run mysql from a DOS prompt. The second method is to download a copy of MyCC from the MySQL.com website. This program allows you access in a Windows environment.

Re: RH 7.2 connections problems w 16 web servers to 2 MySQL servers
We pay for MySQL support but haven't had much help from them. You could pay me, I need work... :) Seriously... We have a very high volume site (3 million page views a day) that's run on 16 Apache / PHP web servers 2 MySQL servers. We are using PHP with persistent connections. Each MySQL serves 8 web servers is supposed to act as a failover machine for the other group of 8 web servers. Nice. We have over 3 million page views a day also (for forums -- a recursive query application if there ever was one -- that is, lots of queries per page), though we use two hand-made dual Athlon machines (one apache/php, the other mysql). Its amazing what you can do with less than $10K. Once upon a time we had 4 web servers in front of 2 mysql servers. I've gone through this before. More below We get a mysterious MySQL lockup once a week at the same day time. No idea. Does it just pause for a bit? Are there any cronjobs? Can you get a mysql process list? Questions : - Is our configuration of 2 sets of 8 Apache/PHP web servers 1 MySQL servers just not a good idea ? Just will need some work... - Would we better off with FreeBSD ? No, that is not the issue. - Is there anyone doing any similar setups with lots of web servers a few MySQLs ? We had 4 per mysql server before, not as big but has the same issues. - Is there any way to get Apache / PHP to use fewer connections ? Yes. First a few questions: - How many Apache servers? 8. - Are you using HTTP Keep-Alives? - Are you using persistent connections? Yes. - What is connecting to mysql (PHP, an Apache module, Perl, JSP)? - What is Apache's http.conf value of MaxClients? - What is Apache's http.conf value of StartServers? - What is Apache's http.conf value of MaxRequestsPerChild? Multiply these three numbers: # of apache servers # of apache's MaxClients # of unique server/user/pass pairs The result is the ceiling on the number of connections needed for mysql. When one goes down, then you will multiply by two, since you have twice as many web servers in that situation. Note this number and work it into MySQL's documentation for memory requirements for the MySQL server. You may be shocked. If you are in an emergency, do this: A. Turn off apache's HTTP Keep-Alive B. Turn off persistent connections C. Up the number of cached threads for mysql That should immediately help. There is a more optimal solution, but the amount of work to properly tune will take at least another email and the answers to the above questions.

Re: Many processes in SHOW PROCESSLIST;
PMFJI, but has anyone done any testing to see if persistent connections with MySQL and PHP is actually faster in practice? Without testing, I suspect that it is faster but that the gains are very small. If this was Oracle, it'd be a whole different story. The connection overhead in MySQL is minimal. With MySQL's thread_cache, the connection overhead is even lower. PHP's persistent connections can be good or bad. If you have a small site, low traffic, etc., it will help. If you have lots of traffic, then it can make more problems than it solves. PHP's implementation of persistent connections is flawed. A connection is persistent per process, not per server. Depending on you Apache variables, this can cause MySQL to have a _lot_ of useless threads running. And they take up memory. And that can slow things down and push MySQL to crash (setting a limit on MySQL connections solves this crash problem). Maybe with a new MySQL module for PHP in the works, this will get fixed. It needs to use shared memory so multiple apache processes can use the same connection pool.

Re: Any way to hint a particular index for a query?
Any way to hint a particular index for a query? From the manual (http://www.mysql.com/doc/J/O/JOIN.html) As of MySQL Version 3.23.12, you can give hints about which index MySQL should use when retrieving information from a table. This is useful if EXPLAIN shows that MySQL is using the wrong index. By specifying USE INDEX (key_list), you can tell MySQL to use only one of the specified indexes to find rows in the table. The alternative syntax IGNORE INDEX (key_list) can be used to tell MySQL to not use some particular index. USE/IGNORE KEY are synonyms for USE/IGNORE INDEX. Also, have you done an 'analyze table iv_alert'?

I assume you are talking about bdflush only at 100% (I'm actually trying 90%). Thing is, all our tables are constantly changing.

Re: MyISAM RAID Tables in the MySQL-MAX Binaries?
Are RAID tables supposed to be enabled in the -MAX binaries? They appear not to be (in 4.0.1), and that surprises me a bit. I thought RAID tables were retired in MySQL 4. It was only a split for the data files anyhow, not the index files, so it was incomplete at best for getting around the lack of large file support in some (now old) OSes. For speed, RAID is best handled by the OS or hardware.

Re: mysql and onboard ide raid
As for a filesystem. I wouldn't recommend ext2 or ext3 at all. I would _highly_ recommend a journaling filesystem such as Reiserfs (http://www.namesys.com) or XFS (http://oss.sgi.com). I've used reiserfs for a long time, but XFS is growing on me. It seems to be more stable in latest 2.4 kernels. I don't know the reason for this. I'd refer people to http://www.linuxjournal.com//article.php?sid=5840 Although that article talks about Oracle, we also found ext3 for mysql data disks to be the best choice from our own experience. Reiserfs jams with lots of small files though; useful when compiling (mysql source for example) or for a webserver. Actually, I like it for everything but the mysql data dir. Is it better to take Raid level 1 or 0 ? RAID 0 or RAID 0+1 with a lot of disks makes a huge speed difference under load. SQL server speed (trx/s) can correlate to the rotational speed of the disks once the server is disk bound. RAID 0 lets you increase the effective speed of the virtual drive by summing the speed of the disks (roughly). I have no experience with IDE RAID though. SCSI still outperforms and likely always will.

RE: load formula
This should probably be on the main MySQL list. I think I'd use the one minute load average from the servers (assuming they were all on the same OS/version), and cache it for a minute (you don't want your pings to add to the load). That is, if you don't need 1minute resolution. The load is a good indicator since it will take into account the complexity of the queries running. With more resolution, nothing is very good, but almost anything will likely do, AFAIK. BTW: Have you looked at: http://www.firstworks.com/sqlrelay.html SQL Relay is a persistent database connection pooling, proxying and load balancing system for Unix and Linux supporting ODBC, Oracle, MySQL, mSQL, PostgreSQL, Sybase, MS SQL Server, IBM DB2, Interbase, Lago and SQLite with C, C++, Perl, Perl-DBD, Python, Python-DB, Zope, PHP, Ruby and Java APIs, command line clients, a GUI configuration tool and extensive documentation. The APIs support advanced database operations such as bind variables, multi-row fetches, client side result set caching and suspended transactions. It is ideal for speeding up database-driven web-based applications, accessing databases from unsupported platforms, migrating between databases, distributing access to replicated databases and throttling database access.

This is highly application (and configuration) specific. If both servers are doing identical work, then anything like the above (or better, find the number of queries in the last second) would work. The number has no meaning. Depending on HTTP Keep-Alive and your setup for connection pooling, the threads number can either be constant or the most important number. If we assumed the you are talking about a web server and not doing connection pooling (which is not such a great thing to do in PHP, for example) then the number of threads will be all you need. It will say how many queries are currently being processed on each server. BTW -- why not check the actual 1 minute load average on the servers?

Re: Distributed Fulltext?
[comparisons to Google...] While any speed up with a full table fulltext search would be helpful and useful, there are instances where the search is intersected with another column and the problem of search is therefore more complex but also leads to potential optimizations. In our case we rarely do searches that use just the FTS index. More commonly, we do searches based on other columns and a FTS indexed text column. The WHERE clause restraints on the non-text column usually eliminate 99% of the rows. Fulltext indexes can not be combined with numeric columns in a single composite index, so as far as I can tell, MySQL performs the FTS then filters the results to meet the WHERE conditions. I believe the required amount of the index to be paged into main memory is much larger than might otherwise be needed (since the indexes are larger than available memory, and there a zillion other tables accessed simultaneously, this tends to effect all queries). So besides the obvious desire to lower the size of indexes, it would be beneficial if a combined index could lower the number of matching rows and the amount of the index needed to be in memory. I actually find it odd for people to not be using secondary columns in a fulltext search, other than to do something like Google (which does not lend itself to using SQL in the first place. Of course, I have a myopic view stemming from my own requirements and experience. All that said, I'm glad to have the FTS we have. Thanks Sergei for such a wonderful improvement to LIKE '%word%'!

Serialized writes (i.e. replication slave) for two weeks (or about 1 billion insert/update/delete type queries) with no crashes. 2. Everything. We will have the app send duplicates of all queries to the mysql 4 server, but will automatically halt when mysql 4 crashes. We will keep trying this until mysql doesn't crash for a week. 3. Check that the two servers hold the same information and return the same results from queries. With the type and volume of queries that we have, mysql alpha versions either fail within minutes/hours/days or they don't fail at all. We certainly are not the biggest user of mysql, but historically, we have been able to push it hard enough to crash. Not the stable version though. Thankfully, that takes a licking and keeps on ticking. :) Eventually (spring/summer), we will move the main server to v4 and keep the slave around as a live backup.

Re: Distributed Fulltext?

I want to be able to do search of the million records of inventory in our database and find the items with certain keywords, that are currently available for sale, in the venue the user is shopping in and within the price range the user specifies. This is a combination of database and fulltext search that I think is exactly in MySQL's marketplace. Personally I use the term 'search engine' to mean Google-like text-only search. I don't have a term for the above, but FTS seems fine. I agree that MySQL users will tend to want an index over several columns including one that is text (FTS). As for practical advice now, I'll tell you what we did: 1. Got better hardware. Athlons, DDR memory, RAID: more is better. :) 2. We split the FTS tables into 10 tables. Since we do not need to search the text without some other constraint (yet -- I'd like FTS to work with merge tables in the few cases where we did), we know which table to use. Your mileage may vary. This helps for several reasons: less index to pull into memory for the search, and FTS does not seem to be O(n) but rather O(n^2) though I can't be sure. 3. Replicated the table to do FTS on to another computer. All it does is FTS. We made our own routine to replicate the table (actually 10 tables) since our text is compressed on the main server (smaller = less disk access = faster) and the indexes are different (obviously). In this case, it can hold a lot of the index in memory -- big difference. Also, a long search does not lock the tables. This is worth in and of itself. Even if you have this copy of the table on the same server. De-normalization can produce huge speed increases depending on what and how you do things. 4. If you do #2 and #3 you'll notice that you can have x (10 for us) number of servers partition the FTS. We don't actually do this, but we could and therefore get 'Distributed Fulltext' -- the title of this thread!!! Number 1 and 3 should work for everyone, I think. Only if your app can partition, can you do #2 and #4.

Efficiently storing md5
Does anyone have a best practices for efficiently storing md5 hash values in MySQL? Since it is a 32 character string of hex numbers, I originally stored them in a char(32) binary column. But that is wasted space (by a factor of 2). And of course, these things add up, both in data files and indexes. Md5 hash-- 16 bytes. char(32) binary -- 32 bytes. BIGINT -- 8 bytes My thought right now is to convert the md5 hash into two BIGINT numbers and visa-versa. High BIGINT = conv(left(md5,16),16,10) Low BIGINT = conv(right(md5,16),16,10) And reversing: Md5 = concat(lpad(conv(high,10,16),16,'0'),lpad(conv(low,10,16),16,'0')) I suppose there is some point (in terms of the number of rows) where storing more efficiently outweighs the conversion functions, and I assume that I'm past that point. Is there a better way to convert these? Just a note: there is no 128-bit integer type and CONV() only works with up to 64-bit 8-byte numbers anyway.

Re: Slow updates with two keys in where.
Is this just something we have to live with or does MySQL 4 handle this better? Something to live with. Someday, I'm sure MySQL will optimize this case. Conceptually its not that hard. You split it into multiple queries that track an index. If it is a select, you also UNION the results back together. However, conceptually easy does not mean trivial. That is a lot of work for the MySQL team to do and not very high on their list. Better for you to change: update forum set approved='N' where id=644122 or thread=644122 into update forum set approved='N' where thread=644122 update forum set approved='N' where id=644122 Of course, as a (sort-of) competitor, I probably shouldn't say that. BTW - out of curiosity, what sort of through-put does Phorum have? We have two machines, one web and one mysql, that handle 100m pv/m, which ought to hold to 150m/m before we need more hardware.

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: Testing MySQL 4.0 ; detaching queries
You could just exec() the page again, with a parameter telling it to use the test server, like so: I like this general idea, though the above method would take a little more work since I would have to pass the environment variables and apache variables (GET and POST, etc) to exec and I don't know how. However, I can try and setup a test web server on the test SQL server and have a auto_postpend file that sets up all these variables (cookies, post vars, etc) and sends them off using fsockopen, etc., as a HTTP request to the other server. If I setup the other server to ignore hangups, then I can send the request and quit. Thanks for the idea!

I'll bet he is using PHP and Apache and has persistent connection on PHP and Keep-Alive on Apache. The MySQL module for PHP is the biggest barrier to scaling in this situation. All database modules are bad in PHP, everyone knows it, very few have the time, resources, or money to fix things. [Case in point: if I had the money, I'd make the time...] There is SQL relay (http://www.firstworks.com/sqlrelay.html) though I have yet to try it. Has anyone? A quick (partial) fix is to use MM inside PHP so persistent connections act as expected (i.e. shared between processes). Even easier (sloppier) fix is to not use Keep-Alive, use persistent connections, but have the timeout inside mysql be a couple of seconds. That gets a better match between active http processes and mysql threads with the least bit of effort.

Re: Query optimization issue.
mysql explain select * from dominf.domip order by ip desc; 'ORDER BY something DESC' does not use an index. It must be ascending. See the manual. Also, I forgot, if you do this often and it needs to be in DESC order, you can always alter the app to create and use an extra column 'ip_desc unsigned int not null' and set it in an insert to (0x - ip) and have an index on ip_desc. (If the column was signed you would use 0x7FF - thevariable, but ip numbers need to be stored as unsigned).

Re: slow querys
The slow queries are those like... SELECT id FROM table WHERE field like '%text%' AND ok=1 AND type=1 WHERE field like '%text%' -- this will not use an index. Read the manual about fulltext. It may or may meet your needs. It works pretty good. If the text is a word you could also build a word index table. Check the list archives. If you are scanning for something like 'SCRIPT type=' in a field, then you will have little luck. So the answer depends on what you are trying to do (as always).

Re: ASP ADO
In my (limited) experience it's nearly as easy as using ASP/ADO wirth Access. MySQL is a bit touchier about what it considers proper SQL.

Steven Now I have a question: Does this also apply to automatic repair inside Steven mysqld? I'd finally use the feature if its true... If you just run CHECK TABLE, it will repair the open count (it should always have done that). myisamchk --fast --force is equal to: run CHECK TABLE on all tables Run REPAIR TABLE on tables which was not marked as ok. I was refering to --myisam-recover=FORCE As I remember, it would repair tables that had a open count 0 (at least back when I first tried using it).

Help: Replication between 2 tables
Hello, I am trying to set up mysql replication between 4 machines each with version 3.23.38 installed. My problem is that the master database has a table called metadata and the slaves have the same table but called METADATA. Is there a replicate-rewrite-table option, or do I need to trap the selects on metadata and convert them to lowercase in the code to get the replication to work ?...

: log event entry exceeded max_allowed_packet
Hello, I'm trying to set up replication, but I cant get any further than this message on the slave. Error reading packet from server: log event entry exceeded max_allowed_packet My max allowed packet size is 512M which I've gradually reached while trying to stop the above error message. Is this the real problem or is there another issue causing this ? Cheers Steve Goodliff
Re: MySQL 3.23.39 released
Changes in release 3.23.39 -- * Fixed problem with shutdown when `INSERT DELAYED' was waiting for a `LOCK TABLE'. * Running `myisamchk --fast --force' will no longer repair tables that only had the open count wrong. -- THANK YOU! You don't know what it was for the first item to require a forced shutdown that made myisamchk take a huge amount of time. Although we have not had the need for a `myisamchk --fast --force' in a while, I tell you if you had a big fulltext index, you would avoid it like the plague. Now I have a question: Does this also apply to automatic repair inside mysqld? I'd finally use the feature if its true...

Nesting DATE_FORMAT
Hello I am trying to display a table depending if the registration date is between a certain period. To do this , I want to pull the 'day' field from another table and construct one of the comparison dates with this value. It is probably best explained with a query. This is what I am trying to do: SELECT whatever FROM tbl1, tbl2 WHERE ( tbl1.registration_date = DATE_FORMAT(now(),'%Y-%m-)DATE_FORMAT(tbl2.registration_date,'%d') AND tbl1.registration_date = DATE_FORMAT(now(),'%Y-%m-%d') ) AND tbl2.id=1000 So both tables have their own registration_date, and I am trying to display rows when the registration_date of tbl1 is between the day of tbl2 joined with todays month and year AND todays date. e.g. if the reg_date in tbl2 is 2000-12-15 and todays date is 2001-05-29, it should display any records of tbl1 that have a registration date between 2001-05-15 and 2001-05-29 This is for a payment system, where accounts are paid on the registration date as defined in tbl2 each month, and they can check what accounts they will be getting paid for during the month. I am doing this in a PHP script and can pull the day out first then pass it in a second query. Was trying to find a way to do it in one query. Any tips or hints would be extremely appreciated. Thanks! Have a good one.

Choosing between the three types of transaction-supporting table
Hi folks, The recent additions of storage handler for transaction-supporting table confuses us. From what I read on the list, Innobase is generally much faster than BerkeleyDB. But I can live with slower speed since my application will not be expecting high rates. It is reliability and tested product which I am more concerned with. Could somebody provide a general overview and comparison of BerkeleyDB, Innobase, and the upcoming Gemini? Regarding speed, space efficiency, recovery, and memory footprint. Better still if it ends with the practical advice on choosing between them (i.e.: you should choose Innobase if ..., but use BerkeleyDB if ...). I believe that is also a manual/FAQ material.

More on: mysqld got signal 11
Hi! I have received several emails from people that choose not to (or can not) post to the list about mysql segfaulting. At the moment, I have the segfaults stopped by doing all of the below, I don't know (yet) which are to blame or in what combination: 1) Eliminate insert delayed (not really needed anymore, anyways) 2) No fulltext search 3) Increased file descriptor limits (again!) 4) Find and eliminated bad format queries, particularly insert delayeds that cause a error. After a few days of no segfaults, we are going to allow fulltext again, the other changes can (and should) remain permanent. NOTE: From the emails I received I could find two trends that _may_ be the source of segfaults: 1) Not enough allowances for open files (#3 above) 2) Insert delayed AND poorly format queries AND high load REQUEST: Can we make an option in mysqld to log bad queries? Re: 'You have an error in your SQL syntax ...' PS - we do not use autoincrement in insert delayed tables.

The server has worked flawlessly for months over various mysql versions including this one. Only when the replace delayed (and selects) on the fulltext tables occurs, does this appear. Is there a binary of a debug version for Linux? I'd like to catch the server going down with more information.

Re: mysqld got signal 11
Hi, Ah, today's problems are from a bug that dates back a year or more. Streaming a large number of insert delayeds into a table that does not exist causes the crash.

RE: mysqld got signal 11
I have tried the above with 3.23.33 and was not able to reproduce it. I could be wrong (imagine that!). It crashed again today even with the table in place. In order to take one item out of the equation, I stopped the replace delayed process I had running. It still crashed (about 8 hours later). Since it takes this long, I can't do a trace file -- it would be larger than our hard drives. I'm enabling the log on this server today -- hopefully that will help, and will be smaller... Right now the only thing I can think of that is different (since the server never used to crash before): 1) Fulltext searches (selects) are happening on this server. 2) I switched the apache servers to _not_ use persistent connections (in most cases -- I just realized we are currently using a 50/50 mix). So my plan right now is to do this: 1) Turn on the log and see what is there when it crashes. 2) start again but don't have fulltext searches 3) start again but use persistent connection and do have FT searches 4) start again but use persistent connections no FT searches 5) cry if it is still crashing ;| Pertinient information(?): 010307 2:03:36 Aborted connection 580760 to db: 'logging' user: 'apache' host: `tank' (Got timeout reading communication packets) mysqld got signal 11; The manual section 'Debugging a MySQL server' tells you how to use a stack trace and/or the core file to produce a readable backtrace that may help in finding out why mysqld died Attemping backtrace.

Re: shutdown and insert delayed
Hi, I was trying to use debugging (creating a trace and log file) in order to find the crashing problem we have been experiencing. However, I tend to come up against another problem in the course of things -- mysql not shutting down. This time I have a log file and a trace file.

RE: mysqld got signal 11
An update: o I found other queries that were insert delayed into non-existent tables and others that had wrong column names. Removing these, I thought would fix things. Nope. o I tried writing a log and a trace file. Too slow and unworkable. I tried just log (worked OK -- I got a crash but nothing looks abnormal in the log) and I tried just trace (still too slow). Trace with just info and error runs but didn't give me enough info to help. Lots of 'vio_read returned -1, errno: 11'. o Right now we are going to see how long we can run with no fulltext insert/replace/update/select.

RE: INSERT/REPLACE lock up in 3.23.33
Safest thing for you is to use our latest 3.23 binaries which are statically linked with stable glibc and with some additional patches. For this reason and greater simplicity :) I have been using your binaries for a long time now. Part of the reason we never tested BDB tables... There can be another source of problems with REPLACE. As it has to DELETE a row first, it might take a lot of time on huge table if MySQL is not able for some reason to utilize index in order to locate rows. Now this seems like it might be related. On a variable sized row table, this could be a source of problems. As a note, there is a unique index it should be using. Is there a way to see if it is, or USE INDEX like select?

Please HELP easy ANSWER
Hi Everyone, I have a big problem, that I bet could be solved pretty simply but I am new to mysql so its killing me and my database. Ok heres the problem, suddenly out of no where when my php script tries to (or manually) do a insert it says: ERROR 1062: Duplicate entry '127' for key 1 Now why all of a sudden is this doing this at id 127? This is what my create table statement looks like if this is of any help to you: CREATE TABLE custinfo ( id tinyint(4) DEFAULT '0' NOT NULL AUTO_INCREMENT, date date, name varchar(50), card varchar(22), exp_date varchar(7), authcode varchar(8), amount double(4,2), tax double(3,2), pnref varchar(16), address text, city tinytext, state varchar( 3), zip varchar(15), country varchar(2), contact_first varchar(20), contact_last varchar(20), contact_phone varchar(20), contact_ema il tinytext, tickets tinyint(3), description varchar(50), PRIMARY KEY (id), UNIQUE id (id)); Now after I got this message these are some of the things I have tried to solve the problem but of course had no success: I tried isamchk -r and -R, i have even tried it with -rkis and then just plain -kis i pretty much have tried them all and it still gives the same error when i try to insert anything into the list ? What do i do to fix it and what did i do to cause it? Please help me I need this database up and running (loosing money every hour its down!) :( please please please help thank you very much for your time and help. -Steven Steven Fruchter Chief Technology Officer SMR Studios, Inc.

client connection timeout
Hi! We are using PHP and want to detect if a MySQL server is available or not, but do so very quickly. Will the MySQL library in PHP use a connection client timeout? Can this be set under [client] in /etc/my.conf? Also, what is the connection is a persistent connection, and the server goes down, but PHP has not yet noticed? Is the configuration different? Thanks!

INSERT DELAYED and FULLTEXT and locking problems
Hi all, I was curious if anyone has been experiencing problems with INSERT DELAYED lately. At the moment, it seems to limited to INSERT DELAYED and tables with a FULLTEXT index. After a while, a lock on table prevents any normal INSERTS or SELECTS (this behavior may require doing both normal and delayed inserts, but I'm not sure... its either that or its the fulltext index. Insert delayed on a fixed size table with no fulltext index and no normal inserts works without error). The lock persists even when the delayed handler is empty (Not_flushed_delayed_rows is zero). I'm using MySQL 3.23.30 So anyway, I tried doing a flush tables. Bad idea!! Bad! It waits for the tables in question, and does not allow new insert delayed handlers to start up. The process list fills up with 'Creating delayed handler' and sends the server down as it fills all possible connection slots. Shutting down does not succeed. I was curious to hear any related stories that might help me create a test case.

RE: Large Table Problem
Hi. You posted to the wrong list. This list is for developing of MySQL itself. As for your problem, MySQL does not have a good solution at this point. Have you tried using the BACKUP command? It will flush and lock the table and copy only the data and .frm files. A RESTORE will rebuild the index. This, I think, will be faster. Otherwise, do you have an updatelog and a backup? And depending on your application, there are other things you can do. Is there a timestamp or autoincrement field? Are there only inserts going on? You could copy smaller sets of the table until done for example.

RE: TRUNCATE causes corrupted tables
Hi! No, I can't repeat it on command, sorry. However, I can give a little more info. When inserting, the index file got bigger. It was the data file that was set to 0 bytes, but did not get bigger on inserts. Doing a repair fixed it. I have some tables truncated via scripts, so I turned on mysql's auto repair feature so it can deal with it rather than me.

RE: What does this mean ?
This patch will make it into 4.0.5, I believe. 4.0.4pl1 fixes only two bugs (one security issue, and one that make the PDF plugin work again). My patches could have side effects, since it will run code that has never been run before (like actually closing those persistent connections). They are in CVS. If you are using Apache (most of us are with PHP), note that persistent connections are per process, not per machine. Mod_ssl can use an Apache extension to keep shared memory across processes, but PHP does not. Read the docs (or the PHP list) to find out more. Sincerely, Steven Roussey Network54.com http://network54.com/?pp=e That is what I suspected. I suffer the same. The problem is buggy PHP persistent connection code. The "almost good" solution was presented to PHP people by Steven Roussey (http://marc.theaimsgroup.com/?l=php-devm=97562841130973w=2) and (http://marc.theaimsgroup.com/?l=php-devm=97858730928909w=2) and according to Andi Gutmans (http://marc.theaimsgroup.com/?l=php-devm=97858932431876w=2) the patch was committed to PHP CVS. However the patch is absent even from PHP 4.0.4pl1 (its zend_list.c is dated 2000-10-20). You might try to patch your PHP by yourself. Or try the latest snapshot from http://snaps.php.net (though I don't know if the patch is there). Sincerely speaking I don't know why Steven's patches haven't been incorporated into PHP 4.0.4pl1. Maybe Andi (Cc:ed) could explain this?
