Re: default table type = innodb is stable??
Is that stable if i started mysql server by defining default_table_type = INNODB at the my.cnf file? from which by default my.cnf is defining MYISAM table to be the defaulted. Richard Dale wrote: this is my error log file. InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes InnoDB: than specified in the .cnf file 0 268435456 bytes! Your problem here is that you must have started MySQL when you had a 5MB transaction log file specified, but you then put a new config file online with a different log file size (256MB), InnoDB complains and dies. You need to delete your old transaction log files (ib_logfile0) then start MySQL and all should be fine. Note: You should only delete your log files when you are absolutely sure MySQL has shut down OK. Best regards, Richard Dale.

Newbie: MySQL cluster configuration
hi, i want to configure a two-machines mysql clusters. i have compiled from source by enabling the clustering feature with no problem at all. i read the documentation on mysql. but, i am not understanding on how to make a simple mysql cluster. basically, i just want to have a kickstart. that's all. i have a config.ini file at my /usr/local/mysql/mysql-cluster, as such [NDBD DEFAULT] NoOfReplicas= 1 [MYSQLD DEFAULT] [NDB_MGMD DEFAULT] [TCP DEFAULT] [NDB_MGMD] HostName= node1.mysql [NDBD] HostName= myhost.example.com DataDir= /var/lib/mysql-cluster [MYSQLD] [MYSQLD] [MYSQLD] then, when i start ndb_mgm, i get this.

archive data
hi, i am using linux redhat 8 to power mysql. i installed mysql version 4.0.13 using rpm package. by default, the data file of mysql is alocated at /var/lib/mysql, but i have a limited of diskspace of /var dir (it is about 1G), so, it was easily full loaded with data. now, i want to archive the data into another dir. how can i switch the dir such that, i can have a spacious diskspace to store my data. now, i am facing a problem that i cant write into the db because of the no diskspace left. how can i archive my data, then, switch the storing location to another dir (previously it was /var/lib/mysql) which has bigger diskspace. then, restore the data. how can i do this? pls, advise. thanks Cheers, yenonn -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
