Change to the Oracle GMS Daemon

In Sun Cluster 2.2, Oracle's Group Membership Services (GMS) daemon is no longer started as part of the Sun Cluster framework with scogms(1M). This means that for Oracle Parallel Server databases, the GMS daemon must be started manually using the binary ogmsctl that is provided by the Oracle Parallel Server Option installation on a cluster node. The ogmsctl daemon must be up and running even when the instance on the node is started in exclusive mode. Therefore, this daemon should be running when the database is created.

The GMS binaries ogms and ogmsctl are located in the /bin directory under $ORACLE_HOME. The default home directory for the GMS daemon is /tmp/.ogms. This directory contains trace files and the gms0000.dat file.

The GMS daemon must be started from the oracle user login. The following commands start the GMS daemon.

# su - oracle
$ ogmsctl start

For the daemon to start successfully, the node upon which it is run must be a cluster member.

The following command stops the GMS daemon.

$ ogmsctl stop

The ogmsctl command has the following options.
