Explanation

An ENQ macro was issued with a resource name of TCPIPSYS.task_name, requesting exclusive use. The ENQ invocation failed, with the xx portion of the completion code being the ENQ return code.

System action

The system ends the task.

Operator response

If the error was an unintentional attempt to start a TCPIP task that was already active, then no actions are required. Otherwise, tell the system programmer about the error.

System programmer response

If the error was not because of an unintentional attempt to start a duplicate TCPIP task, examine the task completion code. For information about interpreting the return code, see the z/OS MVS Programming: Assembler Services Reference ABE-HSP. Follow recommended problem resolution procedures indicated by the appropriate MVS™ diagnostics manual.

Note: The ENQ was issued with the RET=USE parameter.

If problem determination indicates that the MVS platform is in error, gather all available documentation, and report the error to the IBM® Software Support Center.
