Events in pool-specific TD queue records
Pool-specific TD queue records report a number of events relating to problems with connections and pool definitions.
- SESSIONLOST
- An active connection has failed. A probable reason is that the
back-end system has failed. However, this error is also generated
when an operator cancels an active connection. Recommended actions: The following operator actions are recommended:
- Investigate the condition of the connection from a z/OS® Communications Server viewpoint. The z/OS Communications Server sense code that describes the problem is in EVENTDATA. For more information about the sense codes, see z/OS Communications Server: SNA Messages and z/OS Communications Server: IP and SNA Codes.
- Check whether the back-end system is still running.
- Check that the back-end system has not
closed
the FEPI simulated terminal.
- SESSIONFAIL
- A connection has failed to start. Probable reasons are a setup
inconsistency or a failure of the back-end system. FEPI automatically
retries the acquire request several times at intervals; the count
in EVENTDATA shows whether there will be any more retries. However,
this failure is also generated when an operator cancels the connection.
Recommended action: After FEPI stops retrying the acquire request, the following operator actions are recommended:
- Investigate the condition of the connection from a z/OS Communications Server viewpoint. The z/OS Communications Server sense code that describes the problem is in EVENTDATA. For more information about the sense codes, see z/OS Communications Server: SNA Messages and z/OS Communications Server: IP and SNA Codes.
- Check whether the back-end system is still running.
- Check that the back-end system has not
closed
the FEPI simulated terminal. - Check that the terminal type definition in the back-end system matches the FEPI device type.
- ADDFAIL
- An attempt to add a target or node to a pool has failed. A probable
reason is that there was an attempt to add a resource that is already
in the pool. This situation indicates a possible logic error.
Recommended action: Report or investigate the possible application logic error.
- DELETEFAIL
- An attempt to delete a target or node from a pool has failed.
A probable reason is that there was an attempt to delete a resource
that is not in the pool. This situation indicates a possible logic
error.
Recommended action: Report or investigate the possible application logic error.
