The OSS Message-Queue Server
The backup server process preserves message-queue data as well as the queues
themselves if the primary server process fails. You can control the processor in which
the backup server process runs.
You can start and stop the OSS message-queue server using the OSS Monitor SCF
commands START SERVER and STOP SERVER (see START SERVER Command
on page 12-66 and STOP SERVER Command on page 12-82 for detailed information
about these commands).
If the OSS message-queue server fails completely, you can restart it. Server failure can
be detected from the Event Management Service (EMS) messages issued to your
system logs.
