add one more innodb_data file when I do have an autoextending one?
I have an production MySQL-Max -3.23.54a server running innodb databases. I've migrated the server and data from an older Linux installation (with max filesize 2GByte). The new server is running Linux 2.4 and can deal with larger files. I have three in innodb_data files and the last one is autoextending and it's soon full. My innodb_data_file_path looks like this (wordwrapped in order to make it readable). innodb_data_file_path = disk1/innodb/ibdata/ibdata1:2000M; disk1/innodb/ibdata/ibdata2:2000M; disk1/innodb/ibdata/ibdata3:100M:autoextend:max:2000M Can I remove the autoextend option on the last data_file, and add a new one wich is autoextending? Will mysql make the ibdata3 file like the other files automatically? Does it work or will I lose data? I want to do this with as little downtime as possible. I've tried to add a ibdata4 file thats autoextending but MySQL only supports one autoextending file. /Lars sql,query - 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?

RE: mysql fills the disk with temporary files?
Mysql is installed properly with user mysql and group mysql. What happens if I limit the maximum filesize for the mysql user? When it reches that size it will send what kind of errors to the user doing the query? Another problem is that I have quite big innodb data-files, owned by mysql, the limit would also stop the auto-increase files from growing I guess? That's the primary reason. Another reason is the normal MyISAM datafiles, some of them are quite big also. Thats a few reasons that makes me want to solve this on the mysql-server level instead of at the OS level. - lars On Thu, 31 Oct 2002, Jan Steinman wrote: > >From: Lars Andersson <[EMAIL PROTECTED]> > > > >Thanks for your advices, but I don't want to solve this problem on the > >OS/shell level. > > Assuming MySQL is installed properly, with its own user and group, I don't see why >you should not want to solve the problem this way. > > - 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?

Re: mysql fills the disk with temporary files?
Is there any way to put a limit on the size of temporary tables? Or is it possible for my users to put the server down just by creating some kind of big cartesian product as a result of a big join? The server is used in an production environment and it would be a great releaf if there is some way I can stop the users from filling up the disks. -- lars On Thu, 31 Oct 2002, gerald_clark wrote: > You may have a malformed join that is giving you a very large result set. > These would be the temporary tables. > > Lars Andersson wrote: > > >Hi, > > > >I manage a mysql server with a few hundred users.

RE: mysql fills the disk with temporary files?
Thanks,
Unfortunatley I think things will break if I remove the temporary files
while they still are in use =)
I want a solution that keeps the files limited in size. There must be
some settings that controll this kind of stuff.

Re: innodb and freespace?
I have now ReadTheFineManual ;-) and learned that I can use autoextend and create a new innodb-data file by changing my.cnf and restart mysql. I've also done just that with success, now I have an autoextend database file and two static ones. Is there any simple way to monitor the free space of my databases? I can allways monitor the size of my autoextend database, if it grows to big I need to create more files. There must be some way to monitor this with mysql commands, I haven't find any. If I do a show table status now it does only show the free size in my current file, not the size it would have if it had grown to it maximum size. /Lars On Fri, 18 Oct 2002, Lars Andersson wrote: > I have a question about innodb, some of my users get an error code 1114 > saying that a table on an innodb database is full. > > When I do a show table status i get the following size comments (all > tables display one or another of these two). > Comment: InnoDB free: 5849088 kB; InnoDB free: 3072 kB > Comment: InnoDB free: 3072 kB > > How come it says InnoDB free: 3072 kB when I seem to have 5849088 kB > free?

load problems on mysql 3.23.52 with and without Max
I'm managing two database servers, one 3.23.52 and one 3.23.52-Max (using innodb tables on that one). They are both running along fine until they suddently start to accumulate a lot of treads (a lot ~= 200-300), the state of these threads is mostly "closing" and "opening" tables. This drives up the load to amazing numbers and I'm forced to shut the mysql-server down. Since I'm running these servers in a shared environment I got a lot of users using these servers, and so far I haven't got any grip on whats causing these problems. I got these problems on both servers (one with max and one without), both servers got diffrent users. I've ruled out hardware problems since I get exactly the same behaviour on two independent servers. It would be great if sombody knows the answer to my questions bellow: - is there any know problems with mysql on linux? or with 3.23.52 that should cause this behaviour - what should I do to find the error, my logs shows nothing pecuilar. I'm currently dumping a processlist each five seconds to a file. regards /Lars - 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?

changing mysqld variables?
I´ve got a problem. If I try to change max_connections in /etc/my.cnf the server refuses to start? Isnt I supposed to put startup variables to MySQL in this file? A file looking like this works [mysqld] #max_connections=200 log log-bin log-slow-queries server-id=1 but as soon as I remove the comment on max_connections it wont start. Not even if I set it to a lower value than the default 100. This is on a linux machine running the latest and greatest MySQL compiled from source. /Lars - 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?

load balancing, high-availability setup
I want your comments regarding a replication and high-availability setup. This is the setup: Load balancer +---+ | Foundry | | ServerIron | | | +---+ / \ / \ / \ / \ Server 1Server 2 ++ +-+ | Apache | | Apache | | Tomcat | | Tomcat | | + | | + | | mysql | | mysql | || | | | Master | | Slave | ++ +-+ I going to use Server I for all queries that changes the database, and server 1 and 2 should both be used for read-only queries. I want both load balancing and redundancy with this setup. The idea is to separate all queries into two kinds, the ones that change the database should go to "inserthost.mydomain" and the read ones to "localhost". This should balance all the reads between the servers and all the inserts should go into the master (server1). I will make a script that checks if mysqld on server1 is sane, else /etc/hosts should be modified in order to make inserthost.mydomain point to Server2, and a Server2 made into a new master. Is there a smarter solution for redundancy/load balancing with MySQL. I would love to have two MySQL servers that permitted inserts/deletes/updates but since there is no locking implemented yet this is sure to cause problems. The ServerIron takes care of the distribution of the load to the web pages, and also the high-availability questions if one of the tomcat/Apache daemons should die. If anyone has implemented a solution similar to the one I am about to launch I would love to hear your comments. /Lars - 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?
