Is Temporary table right approach
Hi All, I have a query which returns the large number of ids which i am using in other queries. I am doing this in PHP. Now the first query can return unlimited number of ids which might create problem in PHP. I want to store this ids in MYSQL through temporary table so that i can access that ids in other queries directly. Do you think the approach is right or there is any other good approach? Please suggest. Regards, Manoj

MySQL replication status plugin
Good morning guys, (and girls), I hope all is well. I've been given the task to, and I quote - Write a Nagios plugin to test the replication status of two servers by comparing the position on the master to that on the slave To save myself a lot of work, I'd like to know if anything has been done in this arena already, I would be over the moon, if someone has beaten me to it, but I am so not in the mood to write one! Any hints, recommendations, and ideas are wholly welcome! --- Kind Regards, Mr Gabriel

Re: MySQL replication status plugin
I'd just write a perl script to do it and return the appropriate status code/message to nagios. Shouldn't be hard at all. PhP or any language that can talk to mysql would work, too. You just mentioned the position, you'll have to compare the names of the binlog files as well: position 100 in file bin-00010 is ahead of positions 9 in file bin-9.

Re: MySQL replication status plugin
I would not compare binlog positions. I would use mk-heartbeat from Maatkit. It tells the truth in a much simpler and more direct way. Instead of checking things that indicate your data is being replicated, just replicate some data and check the data itself. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Shutdown time
Hi, after many years that I've been using mysql (with almost all Innodb tables) I still can't make myself a reason of the unbearably long shutdown times: almost everytime it takes at least 4 minutes to stop completely and to kill the process; sometimes I even had to kill -9 mysqld. Currently I'm running 150 databases, 12415 tables 1694 users and 173682 grants. The servers are configured to use 1GB of innodb_buffer_pool_size, innodb_log_buffer_size =8M innodb_log_file_size =5M out of 4 GB available. Both run on hardware scsi raid. What does the shutdown times depend on, and how can I reduce it?

RE: MySQL runs on 16-cores server
What kind of query do you use? I think that MySQL is scalable in using best query on the multi-core ( or SMP ) server. It is same on InnoDB and MyISAM on over 4-cores.

Re: Shutdown time
Hi! I just blogged about this: http://www.mysqlperformanceblog.com/2009/04/15/how-to-decrease-innodb-shutdown-times/ Short version: mysql set global innodb_max_dirty_pages_pct = 0; and wait until Innodb_buffer_pool_pages_dirty is smaller. Then shut down.

Error msg: MySQL server has gone away
Hi folks -- New to MySQL. I'm developing C-language connector software and, while debugging, I often get the error message MySQL server has gone away if, say, I've stopped at a breakpoint and then issued a call that resembles: mysql_query(pmysql, insert into usrs(usr,email) values(\pete\, \p...@pwilson.net\); ); I can imagine this happening when the connector is running in real life. So: What is the correct and reasonable way for a running connector to deal with this error intelligently?
