This section describes the default condition handling for child
enclaves created by EXEC CICS® LINK
or EXEC CICS XCTL.
Condition handling varies depending on the source of the condition,
and whether an EXEC CICS HANDLE
ABEND is active:
- If a Language Environment or
CEEBXITA-initiated (generated by setting the CEEAUE_ABND field of
CEEBXITA) abend occurs, the CICS thread
is terminated. This
occurs even if a CICS HANDLE
ABEND is active, because CICS HANDLE
ABEND does not gain control in the event of a Language Environment abend.
- If a software condition of severity 2 or greater occurs, Language Environment condition
handling takes place. If the condition remains unhandled, the problem
is not percolated to the parent enclave. The CICS thread is terminated with an abend. These
actions take place even if a CICS HANDLE
ABEND is active, because CICS HANDLE
ABEND does not gain control in the event of a Language Environment software
condition.
- If a user abend or program check occurs, the following actions
take place:
- If no EXEC CICS HANDLE
ABEND is active, and TRAP(ON) is set in the child enclave, Language Environment condition
handling takes place. If the abend or program check remains unhandled,
the problem is not propagated to the parent enclave. The CICS thread is terminated with an abend.
- An active EXEC CICS HANDLE
ABEND overrides the setting of TRAP. The action defined by the EXEC CICS HANDLE ABEND takes place.
