APAR status

• Closed as program error.

Error description

• USER AFFECTED: The issue happens on unix systems only
  PROBLEM SUMMARY: In some cases when a distributed system such as
  Linux or AIX where the agent is installed is rebooted, the agent
  daemon starts before the network services.
  In these cases, the agent daemon starts successfully, but the
  message server that accepts incoming requests fails to
  initialize and consequently the agent is unable to receive
  messages.
  

Local fix

• Restart the agent after network services have started.
  

Problem summary

• PROBLEM DESCRIPTION: TWS agent creates a communication server
  that is used to communicate with the MDM or zController.
  The initialization of this communication server requires that
  network services are up and running, otherwise some system calls
  returning network configuration details could fail.
  If an error occurs during this initialization phase, the agent
  stays up and running but cannot receive messages.
  The fix will try to re-initialize the message server in case an
  error occurs.
  RECOMMENDATION: Make sure that the network system services are
  configured to start before the start of the TWS agent service.
  

Problem conclusion

• The apar will be fixed in TWS 9.1fp3, TWS 9.2fp4, TWS 9.3fp4,
  TWS 9.4fp5
  

Temporary fix

• See local fix
