For information about these features, see InnoDB Plugin 1.0 for MySQL 5.1 User's Guide.

To install innodb plugin on 5.1

1. Check what current state is

mysql> show plugins;

1. Download the correct version.  There are two versions – a tar file and a package.  The package version installs as part of the Solaris OS , but then means we can have no further mysql installs.  So we tend to download the tar version e.g. mysql-advanced-gpl-5.1.47-solaris10-x86_64.tar

1. Put the download into the bin directory eg /ebilldb-master/mysql-bin

1. change permissions i.e.

chown -R mysql:mysql mysql-advanced-gpl-5.1.47-solaris10-x86_64

1. create a softlink to the untarred directory called mysql 

ln -s mysql-advanced-gpl-5.1.47-solaris10-x86_64 mysql

ERROR:

091104 11:12:49 [ERROR] Failed to open the relay log '/var/run/mysqld/mysqld-relay-bin.9339843' (relay_log_pos 233)

Due to the way in which the master and slaves where stopped  the relay logs got out of sync, hence replication would not restart.

Found the solution was to

a) make a note of Master_Log_File and Exec_Master_Log_Pos
