Safe slave shutdown when using temporary tables. Temporary tables are replicated except in the case where you stop the slave server (not just the slave threads) and you have replicated temporary tables that are open for use in updates that have not yet been executed on the slave. If you stop the slave server, the temporary tables needed by those updates are no longer available when the slave is restarted. To avoid this problem, do not shut down the slave while it has temporary tables open. Instead, use the following procedure:
STOP SLAVE SQL_THREADstatement.
If the value is not 0, restart the slave SQL thread with
START SLAVE SQL_THREADand repeat the procedure later.
When the value is 0, issue a mysqladmin shutdown command to stop the slave.
Temporary tables and replication options.
By default, all temporary tables are replicated; this happens
whether or not there are any matching
options in effect. However, the
options are honored for temporary tables.
A recommended practice when using replication is to designate a
prefix for exclusive use in naming temporary tables that you do
not want replicated, then employ a matching
option. For example, you might give all such tables names
norep (such as
norepyourtable, and so on), then use
to prevent the replication of these tables.
