Dual procs definitely do help; we have tried it with dual procs with hyperthreading and without and with hyperthreading seems to be much faster. Besides that, you can run it on any OS; we use Fedora, with Linux 2.6.x. But that's our choice. Until recently, we ran it mainly on Tru64 Alpha boxes. We've recently been looking at new machines. Xeon machines running Linux are great if your databases are small enough for 2GB to be enough memory for the MySQL server. Many of ours are not (the human genome is 3 billion base pairs, for example, so the DNA table alone exceeds 2GB, and that pales into insignificance compared to the annotation tables) For those, we are starting to look at Itanium2 machines running Debian. Like Donny, we're using the 2.6 kernel. MySQL is about twice as fast on an Itanium2 running the 2.6 kernel as it is on the same machine running a 2.4 kernel. We've just received a quad-CPU-Opteron machine and will be testing that as soon as we can find an OS for it that actually works... But just say no to IDE drives! SATA RAID devices aren't that bad, you know, and they are a lot cheaper than equivalent amounts of SCSI storage. We've used NexSan ATABoy devices, which are relatively cheap, and get you a lot of storage in very little space (10GB in a 3U box). Having said that, our production MySQL servers disks are 15K RPM FibreChannel disks on HP StorageWorks HSV110 controllers, which is rather more at the upper end of the scale. ;-) Tim -- Dr Tim Cutts Informatics Systems Group Wellcome Trust Sanger Institute Hinxton, Cambridge, CB10 1SA, UK -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Load remains 100% after queries are done
Hi, My MySQL server is running on a 2-cpu machine with SMP RedHat 9.0. Currently I'm executing a lot of small INSERT-queries on it. My client program is single-threaded using the basic mysql-API functions and causes 20% load. The client closes the connection to the server upon completion of its tasks. Speed of the disks is limiting during these inserts. The mysql server process will hit 100% load on 1 cpu for the duration of the program. However when the client program finishes, sometimes the database process will keep load at 100%. Sometimes, not always, about 25% chance. When this happens, the server process also is too busy to accept new connections. There's no disk activity. Malloc has dropped to levels before starting my client program. The insert queries executed by my client are done correctly, as the tables contain the correct amount of data (that is: on file-level divide table size by recordsize, or check after restarting the server proces). I have to stop-start the database server process in order to make things work again. I wonder how I can avoid these situations. What could I do wrong/better ? sincerely, Mark Scholtens -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Strange error on one table using phpMyAdmin
MySQL users, I have one table in a database which will not allow me to edit it in phpMyAdmin. Every time I try to select the row for editing, I get an error which says tbl_row_delete.php: Missing sql_query. I have 42 other tables in this database, all of which work fine. I have attemped to rename, move, and copy the database. I also tried functions in the Operations tab which I don't understand very well called Check table, Repair table and Analyze table. All of which simply reported that my table was OK. I hope to avoid having to rewrite this entire table, but I am a loss as to how I can get access to it. It seems the only operation it will allow me is to either delete rows or drop the whole table. I am a MySQL beginner and I am most comfortable using it within phpMyAdmin, but I will try and follow any command line instructions anyone can offer that might help.

I have been given a large set of new data, but it is flat file, basically, it looks just like the user table, with the addition of one field called serial. Somehow, I need to take the 100K or so records, which are currently in a table that is called user_tmp and has the exact same structure as user with one additional field called serial, copy each field from the user_tmp to the user table, which should auto-inc the id field, then copy the serial from the user_tmp table along with the id, and put those in the Registered_serials, with serial going into serial, and is into user_id. When all is said and done, I would hope both tables still have the same number of records in them.

Managing Very Large Tables
Hello, I am trying to determine the best way to manage very large (MyISAM) tables, ensuring that they can be queried in reasonable amounts of time. One table in particular has over 18 million records (8GB data) and is growing by more than 150K records per day, and that rate is increasing. Besides the obvious things like better hardware and load-balancing across multiple replicating databases, I am trying to determine how to keep these data sets optimized for fastest queries. In my particular situation, the most recent data is queried most often, and data over 30-45 days old is not queried much at all but still must remain accessible. Each record has an integer time column that is indexed for querying over periods of time. Currently I run a script regularly that moves records older than 45 days from tables in the main database into identical tables in another (archive) database running in the same server process. This seems to speed up the tables in the main database, but I realize that deleting records leaves holes in the tables, and that this slows inserts as well as makes it impossible to read and write concurrently from these tables. My question is, is it better to keep all of the data in the original tables to avoid holes, or is 'archiving' records to another database a wise approach? How much does the size of a table really affect performance when querying the more recent data? If archiving is reasonable, is there a way to optimize the tables to get rid of the holes without siginificantly impacting ongoing activity on these tables? Thanks for your time!

RE: Managing Very Large Tables
I did some tests with 20GB tables and several millions of rows a few months back, and what helped improve the performance the most was to separate the (small) columns used for searching from the (large) columns containing data. My test table was from a messaging system, and I redesigned it so that the larger table hold only a message-id and some TEXT-fields, and the smaller table held all usernames, timestamps, and other columns used for selecting and sorting. Using the older table design, I tried to set the primary key as optimal as possible so that the most frequently run query could use it directly. However, since I used InnoDB, the primary key *is* the table, doing index searches is rather slow simply because of the amount of disk you have to traverse to get to the index. Adding secondary indexes and forcing the queries to use them did not help. When I changed the structure, the info table shrunk to a few hundred MB, and searches in that smaller table and index was considerably faster. Getting data from the data table was also very fast, since all access to it was reduced to primary key lookups instead of index scans. All of this combined made my queries go ten(!) times faster. I don't know if you can do the same, if you have large data-columns you can split off, but if you do, it won't hurt that much to try. :-) I also don't know how MyISAM compares to InnoDb in this specific case, maybe the result is smaller for MyISAM because of the difference in how the primary key is created and used. /Henrik -Original Message- From: Chad Attermann [mailto:[EMAIL PROTECTED] Sent: den 30 mars 2004 19:42 To: [EMAIL PROTECTED] Subject: Managing Very Large Tables Hello, I am trying to determine the best way to manage very large (MyISAM) tables, ensuring that they can be queried in reasonable amounts of time.

In my particular situation, the most recent data is queried most often, and data over 30-45 days old is not queried much at all but still must remain accessible. Each record has an integer time column that is indexed for querying over periods of time. Currently I run a script regularly that moves records older than 45 days from tables in the main database into identical tables in another (archive) database running in the same server process. This seems to speed up the tables in the main database, but I realize that deleting records leaves holes in the tables, and that this slows inserts as well as makes it impossible to read and write concurrently from these tables. My question is, is it better to keep all of the data in the original tables to avoid holes, or is 'archiving' records to another database a wise approach? How much does the size of a table really affect performance when querying the more recent data?

storing files in blob field
Hello, i try to store some files into a blob-fields of a myisam-table at mysql 4.1. If the file includes bytes with hex-value 00, mysql will only store the bytes before this ' 0-byte ' . How can i store a file including bytes with value 00? Thanks, Michael Scholz
RE: Managing Very Large Tables
Tips on managing very large tables for myISAM: 1) Ensure that the table type is not DYNAMIC but Fixed. = Issue the show table status command. = Look at Row Format = if Row Format != Dynamic the your ok else get rid of varchar type columns = Reason: Your myISAM table can grow only to 4GB then it will run out of space even if your file system allows files to grow past 4GB. 2) For selects avoid ranges i.e. SELECT * FROM BLAH WHERE column NOW() - INTERVAL 30 DAY == or increase range_alloc field in my.cnf 3) For pruning as described below, in a maintenance window run optimize table or myisamchk -r -S -a yourtable.MYI to get rid of deleted blocks. This will help keep your query speed consistent and disk utilization lower. 4) Ensure that mysql_safe is off so you can get the benefits of simulatenous reads or simulatenous writes. 5) add --low-priority-update to allow writes to happen in batches after reads have finished. -Original Message- From: Chad Attermann [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 30, 2004 9:42 AM To: [EMAIL PROTECTED] Subject: Managing Very Large Tables Hello, I am trying to determine the best way to manage very large (MyISAM) tables, ensuring that they can be queried in reasonable amounts of time.

RE: Getting around 2 queries
One option would be to 'union' the two queries (assuming the columns are the same type and length), allowing you to run one query string: Select serial from blacklist where serial = x Union Select serial from seriallist where serial = x Would return 1 or 2 rows, depending on whether rows are found in one table or both.

RE: ibdata1 size

I have done 4 MySQL dumps and some inserts / updates etc but all low volume. Is there some setting I need to have to keep the size of this file down, or is there a maintenance task to clear it out? You can turn autoextend off. Add another disk and extend another data file onto it as autoextend. Remember INNODB is a virtual file system, it also stores the index file (3.X - 4.0.X) in a single file. It also uses a page system (16KB by default), this page system does not map to the block disk device per say. Additionally as it rebalances the Btree it will expand and contract from time to time. In most cases it will expand unless you delete rows. Blobs are particularly affected from innodb. Use myISAM tables for blobs. What is the significance of this file? Any pointers would be greatly appreciated, as my database will be vastly increased in size and disk space may become an issue.

From SQL Server: Jobs
Hi all, I hope I've chosen a suitable list for this post. If not, please feel free to redirect me! :) By day, I am a SQL Server (and .NET) programmer. By night, my current project (a space-based trading/strategy game to be delivered on the web, should anyone be interested in contacting me off-list) is being constructed in PHP (primarily - some light javascript is bound to work its way in, and there are plans for a java applet chat client to be integrated into the pages), with a MySQL 5.0 back-end. I'm currently prototyping, and trying out a few things which I wish to implement in the long run - hence why I'm using MySQL 5, to try it out (and because I want to house data-related logic IN the database itself - so Stored Procedures are a must). In-between lamenting the lack of views, one of the things I most miss from SQL Server, and which I need, is the Job System. For those unfamiliar with the concept from SQL Server, it is a way to set up one-shot or scheduled tasks to run within the database - these execute SQL statements when run, and can be started manually, from a procedure call, or from a schedule. My current prototype involves creating a small schema, with associated stored procedures, and a PHP script which runs a simple loop, detecting which jobs are cached for execution and then, based on the job-code, loading an XML definition file, creating and executing the required SQL statements. For the most part these will be parameterized Stored Procedures - the 'cache data' will dictate the parameters to be passed in. A future implementation (if the project ever reaches fruition and opens to the public) will likely be based in VB or Java (since those are the two application languages I am most comfortable with -- most likely Java, as then I can run it on both Linux and Windows) and will be dual-mode - running either as a monitoring console, or an 'authoritative instance' which actually provides the loop and executes the queries. To the point. My question: Has anyone out there attempted (or seen attempted) such a thing for MySQL? The need has arisen from the fact that I will need to run a number of regular maintenance jobs (such as a map-expansion routine, and various statistical updates) as well as some ad-hoc processes which I would prefer to handle outside of page requests (these would be 'one shot' jobs). I'm really fishing for comments and suggestions as to this implementation - particularly if there are any fatal flaws in my theory, or if it has already been done - Wheel reinvention is not one of my favourite pastimes!!

RE: How to get around lack of views?
The only idea which presents itself (be warned, this is ugly) is to maintain a set of tables which hold the same data, partitioned out by privilege, and to grant access on those tables to appropriate users. These tables could be maintained (or recreated) from the source data at regular intervals. Leaves a lot to be desired though, since data consistency (and age) can become issues if updates are frequent... If the data is relatively static, it's just a bit messy.

Re: replicating only certain tables?
You can restrict logging only on the database level with binlog-do-db/binlog-ignore-db options: http://www.mysql.com/doc/en/Binary_log.html I don't want to restrict logging, only replication. I think I figured it out, though, despite the fact that the documentation is completely inadequate on the subject (couldn't find any info at all about this). The documentation reads: Each slave server receives from the master the saved updates that the master has recorded in its binary log, so that the slave can execute the same updates on its copy of the data. I read this as the master sending all of its log data to the slave, and the slave then parsing that data according to its ignore-db and/or ignore-table settings. However, another admin informed me that the slave actually connects to the master and uses some kind of pseudo-query to grab only the log data that it wants. Thus, data from any table listed with replicate-ignore-table is never actually downloaded to the slave at all. Since the documentation is aimed more at replication-for-efficiency rather than replication-for-redundancy, it talks about updating and replicating but doesn't refer directly to how the data transfer itself works.

Importing data to existing system
In a bit of a quandary here... I have a user table and a registered serials table Table data at end of email... I have been given a large set of new data, but it is flat file, basically, it looks just like the user table, with the addition of one field called serial. Somehow, I need to take the 100K or so records, which are currently in a table that is called user_tmp and has the exact same structure as user with one additional field called serial, copy each field from the user_tmp to the user table, which should auto-inc the id field, then copy the serial from the user_tmp table along with the id, and put those in the Registered_serials, with serial going into serial, and is into user_id. When all is said and done, I would hope both tables still have the same number of records in them.

Re: Drop all keys / indexes on a table?
I've been using comand line piping through awk to handle
mass tables modifications and listings. E.g. in your case
something like the following would hit every index, except
the primary keys, in table tablename in the test database.
echo show index from tablename |
| mysql -uuser -ppswd test
| awk '{if($3 !~ /Key_name/ $3 !~ /PRIMARY/) print $1 $3}'
| awk '{print alter table $1 drop index $2;}'
| mysql -uuser -ppswd test
To hit every table in the test database:
mysql -uuser -ppswd -e show tables from test
| awk '{if(NR1) print show index from $1;}'
| mysql -uuser -ppswd test
| awk '{if($3 !~ /Key_name/ $3 !~ /PRIMARY/) print $1 $3}'
| awk '{print alter table $1 drop index $2;}'

Hi,
Take at look at CHECK TABEL - as far as I remember, the CHECK
TABLE EXTENDED
will do a re-index (check index), otherwise some of the other
OPTIMIZE, etc.
can help on this.
Take a look in the exellent manual.

Ugh. I was afraid you were going to say that...
Seriously, there's no way to just 'wildcard' ALL indexes,

add
that as a feature request. We're using 4.0.17 BTW.
What happens if I list out all the indexes that there
_could_ be in one
ALTER line like that, and one of the indexes doesn't
actually exist? Will
the whole ALTER fail?
Here's the situation, I wrote a script that runs

script runs as part of a client update, and doesn't

Did you change the mysql root password by running: mysqladmin -u root password 'newpassword'? If so, try: mysql -u root -p It will then prompt you to enter a password.

Re: MySQL 5.0 - What is really available?
I prefer SQLyog. www.webyog.com Ditto that. I used to use MySQL-Front, but switched when development stopped. I don't miss it really. The structure synchronization and db job agent features are maturing rapidly and work quite well. Saves a ton of time for me.

temp tables rights?
Hi all, Suppose I have a user who has been granted select and create_tmp_table, but no other privileges, on a given database. When I attempt to insert into any temporary table, permission is denied, presumably due to the user not having insert on the database, and no entries in mysql.tables_priv for the new temporary table. Is there an accepted and clean way of allowing users without insert to insert into their own temporary tables? This message http://lists.mysql.com/mysql/156829 from January seems to imply that no such method exists. There are two workarounds: either the one the above message suggests (make the appropriate entries in tables_priv in advance, creating a static allowable set of temporary table names), or grant insert on the database, and then revoke insert on all of the existing tables in the database. This second method seems clunky in two ways: if you subsequently create a new table that shouldn't allow inserts, you need to remember to revoke insert on that table; it also will clutter tables_priv quite a bit. We're using 4.0.17 at the moment; the 4.0.18 and 4.1.1 changelogs don't seem to address this issue. Hopefully I'm wrong, and someone will point out the correct way to do this; if not, what's the preferred alternative?

Record lag functionality in MySQL?

Fulltext search question: words with numbers (ie DB2)
I have a table with the following:
CREATE TABLE foo (
...
description text,
...
FULLTEXT INDEX (description),
...
);
select count(*) from foo where description like '%db2%';
returns 61 rows. Checking them confirms that the word db2 exists as a
standalone word separated either by punctuation or spaces in several of
those documents
using MATCH(description) AGAINST('+db2' IN BOOLEAN MODE) returns no results.
Is this expected behaviour? If so, is there a way to circumvent it?
TIA

By default, the full text indexing engine doesn't include words with
less than 4 characters in. If you are using MySQL 4 you can change the
minimum length via the ft_min_word_len variable. On MySQL 3.x
there's nothing you can do short of changing the actual source code
and recompiling.

SELECT DISTINCT.. ORDER BY.. DESC - bug??
Hi all, Sorry to be so persistent, but I am bringing this up again since noone from the MySQL development team commented on my previous post, and the issue seems very serious, to the point I may start looking to switching away from MySQL, so - please, please, shed some light on this issue!!! The problem is that the performance of SELECT DISTINCT... query seems to depend on the order the results are sorted, DESC being more than 10x slower than ASC (14.77 sec vs. 1.06 sec). == Here is a more detailed description: The table has over 700,000 records. MySQL 4.0.18 running under OpenBSD 3.4 Intel/PIII 900MHz/2GB RAM mysql SELECT distinct billingCycle FROM PhoneCalls ORDER BY billingCycle DESC; +--+ | billingCycle | +--+ | 2004-04-01 | | 2004-03-01 | | 2004-02-01 | | 2004-01-01 | | 2003-12-01 | | 2003-11-01 | | 2003-10-01 | | 2003-09-01 | | 2003-08-01 | | 2003-07-01 | | 2003-06-01 | | 2003-05-01 | | 2003-04-01 | | 2003-01-01 | +--+ 14 rows in set (14.77 sec) mysql SELECT distinct billingCycle FROM PhoneCalls ORDER BY billingCycle; +--+ | billingCycle | +--+ | 2003-01-01 | | 2003-04-01 | | 2003-05-01 | | 2003-06-01 | | 2003-07-01 | | 2003-08-01 | | 2003-09-01 | | 2003-10-01 | | 2003-11-01 | | 2003-12-01 | | 2004-01-01 | | 2004-02-01 | | 2004-03-01 | | 2004-04-01 | +--+ 14 rows in set (1.06 sec) === Thanks in advance!

apologies, I forgot to mention that.
I was aware of this, and just finished changing the ft_min_word_length
to 2 and rebuilding my indexes.
searches for 'SAS' or 'net' yield results as expected, but DB2 still
does not.

Are you sure you are connecting to an InnoDB database and that you are doing
transactions on InnoDB tables?
My code is rather simple:
#Begins the transaction
$dbh-do('BEGIN');
.
.
.
.
$dbh-do('COMMIT');
What does your code look like?
