Hi, I have installed Percona-Server-shared-compat-5.1.43-3.x86\_64.rpm Percona-XtraDB-1.0.6-10-5.1.45-10.rhel5.x86\_64.rpm Percona-XtraDB-51-5.1.45-10.rhel5.src.rpm Percona-XtraDB-client-51-5.1.45-10.rhel5.x86\_64.rpm Percona-XtraDB-devel-51-5.1.45-10.rhel5.x86\_64.rpm Percona-XtraDB-server-51-5.1.45-10.rhel5.x86\_64.rpm Percona-XtraDB-shared-51-5.1.45-10.rhel5.x86\_64.rpm Percona-XtraDB-test-51-5.1.45-10.rhel5.x86\_64.rpm on my CentOS 5.5 64bit server. Do I need to make any changes in /etc/my.cnf to avail the benefits of XtraDB Plugin? For instance, the FAQ mentions that the install process is the same as that for innodb plugin. So by referring to the innodb plugin installation manual, I need to enter the following in my.cnf ignore\_builtin\_innodbplugin-load=innodb=ha\_innodb\_plugin.so;innodb\_trx=ha\_innodb\_plugin.so;innodb\_locks=ha\_innodb\_plugin.so;innodb\_lock\_waits=ha\_innodb\_plugin.so;innodb\_cmp=ha\_innodb\_plugin.so;innodb\_cmp\_reset=ha\_innodb\_plugin.so;innodb\_cmpmem=ha\_innodb\_plugin.so;innodb\_cmpmem\_reset=ha\_innodb\_plugin.soinnodb\_file\_per\_table=1innodb\_file\_format=barracudainnodb\_strict\_mode=1default\_storage\_engine=MyISAM Am I right ?

Did you get any further on this? I have the same doubt whether or not XtraDB is installed. Any help would be deeply appreciated ---

What does your `SHOW ENGINES; SHOW VARIABLES LIKE 'innodb_%';` look like?
