When attempting to start the WA Agent service, it appears to start but immediately stops. There are no messages in the nohup.stdout or nohup.stderr file indicating a reason for the startup failure.
CA WA Agent 11.3 SPX/11.4
UNIX/Linux Only
The reason for startup failure was shown in the <AGENT_DIR>/log/runner_os_component.log. The error in this log showed a permission issue with one of the .odb files in the database directory...

Mon Jan 14 11:56:09 2019: Checking database access for database/transmitter_queue_spool_asp_sch.odb failed: No such device or address .Please check permissions
Mon Jan 14 11:56:09 2019: Database check failed

When the agent starts up, it reads the .odb files in the database directory. If it is unable to do so, it will fail to start.
Check the permissions on the .odb files in the database directory and make sure they are all readable. The file owner of these files should be root with a default 755 permission. Also, ensure none have the sticky bit as that is known to cause a problem when the agent starts.
