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.
