Goal

DESCRIPTION:
This is an "enhancement request" to start SBS server in the backup group of a Automatic synchronized hot
cluster failover setup.

Customer's problem statement -

A backup group running on a non-primary member of a cluster is disconnected from the message bus by not starting the
link drivers, and is also prevented from accessing cluster common queue files (SAF, DQF, PCJ) by not starting the MRS
server. Client library servers and journal servers are likewise not started. Nevertheless, the messaging services of
the local group, provided by the COM server itself, and the SBS server are required in order for the failover group
and its applications to startup and be ready for the hot-failover which takes place as the previous primary group
fails, and the cluster lock is obtained by the failover group.

However, the Selective Broadcasting Server is inhibited from starting. This means that applications which normally are
able to register with availablity services on non-cluster hot-failover backup groups are no longer able to do so
because they are in a cluster.
