help on setup
Hi All, First I am brand new to the list. I have looked at all the FAQ and the docs on mysql.com for this one. I have set up mysql before on 2 different machines with no problems so I am not new at this. I am setting up a cluster of servers. 3 web, 1 development and 2 database servers. I am installing mysql-3.23.47 source on all of the servers which are all linux. I have set up the server on the database server and clients on the rest. I have been able to start the server manually and set up the start up script in /etc/rc.d/init.d with no problem on the database server. I re-booted the linux server and mysql is now a part of the start up. I have also installed Data-Dumper, DBI and Msql-Mysql-modules. Ran all tests successfully. Then ran-all-tests under sql-bench with no problems. When I use bin/mysqladmin version I get the correct results. Here is the problem. Normally I type mysql at the command line and get the mysql promt. On some of my servers I use mysql -p database and then enter the password and get the prompt. On this new installation when I type mysql I get: bash: mysql: command not found I am lost at what I did wrong or where to begin. HELP!!! Thanks in advance.

I have this stuff... http://sourceforge.net/projects/directsql I had to make only a very small change in their demok, Char() typecast in one .pas file, globally, and presto... As this is a native .pas type of interface to MySQL I feel comfortable helping fix it no problemo, going forward. FYI - Someone had bitched about this earlier. If you can't figure it out in 10 minutes with this then "you're not worthy" ;)- I'll take a few questions if the guys at the project above are too busy.

Off-topic: AOL Red Hat???
A front-page article in this morning's Durham (NC, USA) Herald-Sun reports: "AOL Time Warner Inc. is in talks to buy Red Hat Inc., a prominent distributor of a Linux-based computer operating system, an acquisition that would position the media giant to challenge archrival Microsoft Corp., according to sources familiar with the matter." Is this A Good Thing? A Bad Thing? Does it make any difference? Is MySQL AB next? Would that make any difference? What if PostgreSQL, not MySQL, were next? Has this story been widely reported? Is this just a big yawner for the MySQL community? It seems to me that if AOL Time Warner had not only Netscape, but also the whole Linux-Apach-MySQL-PHP brigade in their hands, they would indeed have a powerful armamentarium for challenging Microsoft. I am not currently a Linux or MySQL user. But I have been seriously considering using Linux and MySQL for several personal and speculative projects, as a way of breaking free of bloatware and of corporate hegemony. This news does not seem to me to bode well. How open are the major open source players likely to remain? What do others here (most of whom are clearly more knowledgeable than I) think? Perhaps I should add that Durham, NC, is the home of Red Hat, Inc., and is also my home. --Erv Young - 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?

Shouldn't be a problem. You can put the whole thing in one table with indexes on the various columns you'll be selecting on. In my experience it's best to tokenise the source, date and url information in a seperate table, thus storing the filename, and three integers. 1st integer - Days since 1st Jan 1980 (for example). If you don't need to store the full datetime field, then don't bother, just store a bigint. 2nd integer - Contains a reference to the source. You can store the actual source name in another table, with this reference number against it. (indexed of course). 3rd integer - Same as #2, but contains a reference number for the url. The url being held elsewhere. This will keep the indexes you lookup on nice and small as they store 3 integer values, (make sure you use the correct type of integer, BIGINT probably). If you always lookup on all three values, an index on all three is best. To lookup articles based on url, you check the url_table for the correct reference number. Then run a query on the big_table looking for that reference number. If you have duplicate urls, only store them once in the url_table, as it's just wasteful otherwise. This also makes for a faster url lookup. > I can only imagine how long it would take to search 18,000,000 rows for a > specific url. Checking the larger table with 18M rows would typically come back in well under a second on a 200Mhz PC, although you need around 80M index cache. If all the urls are unique, this table will become pretty large, and you'll need a fair sized index on that too. I would imagine 300M extra would do the trick, if you only index the first 14 characters or so. These figures scale up pretty well, until you run out of memory, when it all gets a bit sluggish. If that's the case, you can store the different tables on seperate PCs to speed up retrieval. After all -- you aren't doing any JOINs. Where it gets interesting is when you get a request to search all of these documents a la dejanews. It's actually not too difficult to build a very fast word search algorithm, but you'll start to deal with proper BIG tables, with billions of rows... You also need to factor in how reliable you want the system to be, and what your acceptable down-time is BTW - Loading tables over 1M records can be a pain in the arse when you need to recover, and there's no easy way to make it quicker.

Help with Database structure..
I need some help with a database design question: To summarize our design (I'll spare you a lot of the details.) We collect text files from 20,000 different sources every day. The actual file is stored as a text file. Each source has its own table which contains a list of the text files, date, title, url, etc. We thought about having one massive file for all this data, BUT, we archive something like 100,000 articles a day. We store articles for 6 months, so this table would very quickly have 18,000,000 rows. Now, we need to select a group of articles based on source and date. We also need to select based on url. I can only imagine how long it would take to search 18,000,000 rows for a specific url. Our CURRENT concept is to have one table for each of the 20,000 sources. This way we can just query the matching table for what we need. The problem is that 20,000 tables can be a bit unwieldy for mysql to handle. If you have any ideas, I would love to hear them.

tunneling mysql client connections with ssh
Hy all, i am just trying to tunnel a mysql client connection via ssh. i am behind a firewall that doesn't let mysql connections through to the outer world. But i can do ssh to the host i want connect to. Tunneling http port 80 with the command ssh [EMAIL PROTECTED] -L 8:localhost:80 gives me access to the http port of the remote machine via port 8 on my local machine. so fra , so good. Then doing # ssh [EMAIL PROTECTED] -L 8:localhost:3306 and connecting to port 8 on my machine with telnet gives me something like Trying ::1... Connected to localhost. Escape character is '^]'. , 3.23.47-log$jhbjhb%kj which i suppose is a prompt from the remote mysql service but then trying to connect to that port with the mysql client i get: # mysql -u username -p -h my.local.hostname -P 8 Enter password: ERROR 2003: Can't connect to MySQL server on 'my.local.hostname' (111) could it be that the mysql client does some extra checks, so maybe the server sends his real hostname or ip address in binary form (thats the signs at the end of the telnet prompt?) and the client realizes that he is not connected to that machine, but to another and breaks up? can i, if this is so, disable that check? I saw some information which said that forwarding mysql connections is possible, but cannot get this to work properly.

Code Contrib: Simple powerful hotcopy
Dear Group:
I have been doing a lot of experimenting with a rather huge database,
and I need to recover from mistakes when necessary. I need to make
live copies.
After spending too long trying unsuccessfully to load DBD::mysql and DBI.pm on
my machine (for mysqlhotcopy), and
and wasting a lot of time recreating indexes, and a lot of disk space & time
using BACKUP, I finally wrote a little
shell script to simply copy a large table and indexes from one database to
another. It works. 70 lines. I used the hotcopy code as a guide.
It's particularly good when you want to copy a huge database before doing
a potentially damaging operation like ALTER TABLE to it. My database is
already 2G data and 2G index, so I don't have time to fiddle with backup
to text. This solution is optimized for big tables. It doesn't require Perl.
Other major advantages of this script over backup or mysqlhotcopy include:
1. Creates the new database and table if necessary (but won't overwrite them)
+. Puts the copied table into a [possibly new] database and checks it's valid.
2. Simple as hell, 70 lines, at least as fast as hotcopy.
3. No options: Usage line sufficient.
4. Doesn't need perl or DBI or DBD::mysql installed to work
5. Keeps the INDEXES intact (for large tables this is *important*)
6. Hotcopy safe, works with mysqld running,
uses LOCK and FLUSH same as hotcopy.
7. Tells you what it's doing, and what the problems are, in English.
"How do I copy a table?" is a FAQ, I hope this is a simple answer. The others
never worked too well for me.
Of course it's a first cut, and I'm not a shell script expert. The if/fi
syntax is quite ugly and there's probably a better idiom. There's very
little checking or flexibility. Corrections welcome.
Steve

RE: LOAD DATA INFILE Problem
Sorry, my fault, realised the file I was writing for VB was cocking it up. I was adding chr(13) at the end, but the FileSystemObject write method seemed to be putting the carriage return in too, so MYSQL didn't get the newline character.

Re: Why does DISTINCT take so long time ??
Anvar had some very good explanations about the time it takes to run the queries. ##Here are some work arounds: ##If you need to have these columns (mot, date, numresponse) in the group by clause, ##try putting an index on each of them to speed it up. mysql>>alter table searchhardwarefr3 >>add index idx_mot(mot); ##... etc. ##this should speed up the 1st query for sure. ##if the second query is still slow, (i'm not sure about the exact details of mysql, so this might or might not make a difference) ## put the results from your first query into a temporary table (mytemp): mysql>>create temporary table mytemp >> SELECT COUNT(*) as count, numreponse FROM searchhardwarefr3 >>GROUP BY mot,date,numreponse HAVING count>1 LIMIT 100; ## then explicitly index both columns mysql >>alter table mytemp >> add index idx_count(count); mysql >>alter table mytemp >> add index idx_numresponse(numresponse) ##and then run the following query mysql>>select distinct count, numresponse from temp (mytemp) ##by the way, I don't think the HAVING clause is redundant.

I *HAD* a problem running the setup - but found a solution, thought i'd share it with you!
Hi! I downloaded your mySQL for windows (32-bit). I unziped the files into the directory named just the same as the file had (mysql-3.23.47-win). When i then tried to run the setup.exe i got an error saying "can't run 16-bit windows program". This was an extremely irritating thing, since i then couldn't develop anything at home - and had to travel to work in order to be able to do anything (even just slight modifications). So i just let things be that way and went on to work in order to do some work. A few weeks (today that means) later i thought about installing it again, and finding out what was the problem. After some time scanning through your searchable database i couldn't find anything about this problem. I had also been looking for info on the net, and many pages came up with suggestions like replacing certain dll-files in the %systemroot\system32\-directory (Unacceptable for me). After a while of searching, skimming through newsgroups i found this site on the net. http://www.rsc-east-midlands.ac.uk/officeapps.htm My problem was solved. Long filenames brought the whole "unable to run 16-bit windows-programs"-issue to light. The solution for me was to just rename the directory which the setup-files was in to something short like "a", and then everything run perfectly. Some systems info: -Windows 2000 professional edition -mysql-3.23.47-win Now running perfect. I thought i'd let you know, since this was a problem *HARD* to find solutions to.

In boolean FTS, fulltext index works almost like normal index, that is the list of documents is NOT computed in advance. as for combined index, it's possible to do, I think. But I have some plans of changing index structure. This will result in faster searches and smaller index files. With this index structure it would be impractical to introduce compined indexes.

It's the way it was expected to behave :-) The part that I thought could be a "bug" was the one you didn't quote. The problem I am experiencing is that the boolean MATCH/AGAINST FTS WITH an FTS index doesn't match the results returned WITHOUT the FTS index when the same query/parameters are used. I don't know if this is the case when there is no index at all (it would be difficult to test, too). I just found this out by using the USE INDEX clause to switch to using different indices. Incidentally, I have set the fts minimum word length to 1, so the cause of this is not the fact that the index skips some values. In fact, it is the unindexed search that seems to get things wrong. The indexed FTS verifiably works on my data set. The un-indexed FTS demonstrably doesn't work as expected. The unindexed search returns much fewer values. > It's not a "known" bug as the code is rather new. > > Can you create a test case for this ? Possibly, but it could be difficult as my data set changes daily. It looks like a problem that ought to be replicable with fairly generic data. Incidentally, could it be caused by the fact that I am using a multi-column FTS? Could this be where the operation without the index is falling over? Anyway, from what I can see, the indexed FTS works great. The unindexed FTS doesn't (both in boolean mode). Another thing - is it possible to combine a FULLTEXT index with another column/index to achieve a multi-column index with FTS capabilities? It just seems wrong that FTS should take a fixed amount of time regardless of what other indexable restrictions are made on the data set, and if there is a limitation on 1 index per table per query, then the multi-column index is the only way around it. - 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?

Understanding throughput with JDBC
Hello all,
Could anyone please assist me to understand this. I want to understand
where the time is going to and whether there is something I can do about it,
with the following query when using JDBC;
Here is the table declaration;
CREATE TABLE Memberships ("EMAIL CHAR(60) NOT NULL,
NAME CHAR(50) NOT NULL,
MIDDLEINITIAL CHAR(1) NULL,
SURNAME CHAR(50) NOT NULL,
NEWSLETTER CHAR(1) NOT NULL,
USERNAME CHAR(15) NOT NULL,
PASSWORD CHAR(15) NOT NULL,
COUNTRY CHAR(50) NOT NULL,
PRIMARY KEY (EMAIL)) TYPE=InnoDB"
MySQL table memberships has 110080 rows.
Here is the select statement I use with JDBC;
SELECT * FROM memberships ORDER BY EMAIL
Same select statement I use from the MySQL 'commandline';
mysql> select * into outfile 'mysql20.txt' from memberships order by
email limit 20;
My observations;
A. When running the SQL from the MySQL 'commandline' with above statement
this is the response;
mysql> select * into outfile 'mysql20.txt' from memberships order by
email l
imit 20;
Query OK, 110080 rows affected (1.27 sec)
B. When running the exact same select as stated above in a java program
using JDBC, from when issuing, ResultSet rs = stmt.executeQuery(query) until
the java program gets control back, to create the resultset, takes 23-25
seconds; I ran program several times.
Please advise whether this is to be expected, or whether I could alter
anything to get comparable results via JDBC as with MySQL 'commandline'?
Kind regards
Emmanuel

Suse V/S Redhat - mysql performance difference.
Hi list, I have 2 servers 1 running redhat 7.2 and the other running suse 7.3. the hardware config is : RH7.2: Fast desktop (IDE HDD/128 MB memory PIII 550 MHz). Suse 7.3: Low end server (Ultra SCSI 2, PIII 850 MHz, 256 MB RAM). Now i expect to see the suse server go faster than RH, but i am having the reverse happening. The RH server returns a query about 5 times faster. For eg: on RH: mysql> select straight_join docm.document_id, docm.document_title, docm.document_date, sources.source_name, cliptypes.cliptype, byline.byline from keywords, documents_7 as docm use index (PRIMARY), dockeys_7 as dock, sources, cliptypes, byline where keywords.keyword_id=dock.keyword_id and docm.document_id=dock.document_id and docm.document_source_id = sources.source_id and docm.document_cliptype_id = cliptypes.cliptype_id and docm.document_byline_id = byline.byline_id and ( keywords.keyword="assam" ) order by docm.document_id; | 219401 | WRONG POLICIES ARE THE BANE OF ASSAM | 2000-08-21| THE HINDUSTAN TIMES (DELHI)| N. A.| PARASHAR, UTPAL| +-+--+---++--++ 276 rows in set (2.78 sec) same query on suse: | 219401 | WRONG POLICIES ARE THE BANE OF ASSAM | 2000-08-21| THE HINDUSTAN TIMES (DELHI)| N. A.| PARASHAR, UTPAL| +-+--+---++--++ 276 rows in set (7.06 sec) This happens for all queries. Of course the data is the same on both systems. The mysqld is what comes with the distrib. (RH - mysql-3.23.22-6 / Suse - mysql-3.23.41-17). I did try to use the official binaries from mysql.com but, i get the same results on both systems. I will probably install Redhat on the suse system, but can anyone think of why this happens and what can i do to improve the response. As of now the rowcount for the largest table is 221165. Has anyone else noticed similar results?

RE: innodb and vbulletin 1.1
I work for vBulletin and have some input on this. First off, you really should look into upgrading to version 2.2.x, as not only are there many new features, but there have been a number of performance enhancements done that may help your situation. You also might want to take a look at the vBulletin forums ( http://www.vbulletin.com/forums/ ) for MySQL & Server Configuration, where we might be able to give some more tuning help specific to vBulletin. I know a few sites that are using InnoDB, or have tested using InnoDB tables. vBulletin will run just fine in this configuration, however there is one issue many users have run into: InnoDB does not store table counts, so select count(*) from table-name statements can take a while, and there three of these statements on the main index.php page for the total number of users, threads and posts. There are some workarounds you could look into, read this thread for more information on that: http://www.vbulletin.com/forum/showthread.php?s=&threadid=36219 >From the InnoDB manual: InnoDB does not keep internally a count of rows in a table, which would actually be somewhat complicated because of multiversioning. To answer a query SELECT COUNT(*) FROM T InnoDB has to scan one index of the table, which will take some time if the table is not entirely in the buffer pool. To get a fast count you have to use a counter table you create yourself, and let your application update it according to the inserts and deletes it does. A way to eliminate the bottleneck posed by lock waits for the counter is to create a whole set of counters. The application can choose one at random each time. To get the count, just sum the counters: SELECT SUM(counter_column) FROM your_counter_table.
