This is causing some of the sql's on the slave to be slower than master for the same select statement on both master and slave. RES is the amount of RAM used by the process, as controlled by the memory allocation (Linux kernel). It depends not only on the address space requested by the process, but also on those by other processes and on the paging / swapping policy (which AFAIK depends on the which process accesses memory how frequent). The MySQL process on the slave has a smaller RES if and only if there is reason for the Linux kernel to allocate less RAM, this typically means there are other processes requiring it more urgently. *If* the database load on the master is higher, or accesses more data, or there is less competition about the RAM, it is only natural that RES for the slave is less. Database performance strongly depends on caching: If the cache on the master already contains the needed pages, and on the slave it doesn't, it is normal that the first statement needing them has to wait for disk I/O and so is slower.

Re: Master-to-Master replication on same server
You should be able to do this fine. It would help if you specified what the error you were getting was. Atle On Tue, 22 Jul 2008, Jim Lyons wrote: I recently installed 2 instances of mysql on the same server, using port 3307 for the second server, the normal 3306 for the first server. I found that while logged onto that box I could communicate to the 3307 instances using the socket parameter. Using the port parameter (--port=3307) didn't work. I am now trying to set up master-to-master replication on that machine, where the 2 masters are the 2 instances running on that machine (sounds a little flaky, but it's for a dev box and it ought to work). It's not working and I'm wondering if it's because I can't specify the socket the 3306 master needs to connect to on the 3307 master. In the change master to command I can only specify the port. I did specify it as 3307 but the slave still can't connect.

Re: Log
Sorry, not specified what I wanted to get inside the trigger. I would pick who is running the operation.

Re: Log
I need to pass the user of my application pro bank. I want to log the user's application and value of new fields or fields updated. To then have audit of who did what. It is really necessary to create a trigger and a table of log for each table that want to monitor? What do you suggest me?

nested function does not work
Is there are a reason why this wouldn't work? select upper( monarch.group_decode(lower(hg.alias)) ) from nagios.nagios_hostgroups hg; ++ | upper( monarch.group_decode(lower(hg.alias)) ) | ++ | database servers | mysql select lower( monarch.group_decode(hg.alias) ) from mysql nagios.nagios_hostgroups hg; +-+ | lower( monarch.group_decode(hg.alias) ) | +-+ | Database servers | -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: WHERE .... IN
How about: WHERE ( field1 LIKE '123,%' OR field1 LIKE '*,123,%' OR field1 LIKE '%,123' OR field1 = '123' ) Note that this could that a long time on large tables. You'd be better off to normalize your tables ;) How can we normalize the tables? could you explain bit more?

If you can trust the software connecting to mysql, then you can do your logging in the application as a separate INSERT statement just before (or after) each query. If you can not trust it (perhaps it is running on a server you do not control) then you can't trust it to send the logging queries. Logging within a trigger is the safest way to ensure that every query is logged when it is made. Another alternative is to enable query logging and post-process that log to determine what queries were run, and by whom. -- Dan Nelson [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
