When performing database or operating system maintenance, datasources should be temporarily removed from the dataservice and the replicator should be disabled. Follow these rules for the best results. Detailed steps are provided below for different scenarios.
For maintenance operations on a master, the current master should be switched, the required maintenance steps performed, and then the master switched back.
Disable a datasource using the datasource shun command.
Put the replicator offline using trepctl offline.
If you are using the Multisite/Multimaster topology, put the extra
replicator offline using mm_trepctl offline. The
mm_trepctl alias will only work if you configured
Tungsten Replicator with the
--executable-prefix=mm (in [Tungsten Replicator 2.2 Manual]) option.
When making changes to a MySQL system the binary log should be disabled for your session. This will prevent corrective actions from replicating to other servers. Ignore this suggestion if you are making changes to a master that should be replicated.
SET SESSION SQL_LOG_BIN=0;
