CICSPlex SM-requested dumps

A CICSPlex® SM-requested dump may be one of the following:

Abends in the CAS

An SDUMP is scheduled for all abends in the CAS or any address space connected to it, except when:

In addition to the failing address space, the master address space is always dumped so as to provide the MTRACE. If the abend occurred while in cross-memory mode, all the address spaces involved are also dumped. Because the CAS is often required to correctly diagnose a problem, it is always dumped, regardless of its involvement in the failure.

The CAS also provides DAE suppression support. Only one dump is taken for a specific set of symptoms. If it is a recordable failure, LOGREC entries are always written, but only one SDUMP is created. Symptom records are created and passed to SDUMP to prevent duplicate SDUMPs.

CMAS initialization failures

If an abend occurs during CMAS initialization, the CMAS terminates. CICSPlex SM takes an SDUMP with a dump code of EYUXL001 and writes a failure summary to the job log and console.

MAS initialization failures

If an abend occurs during MAS initialization, the MAS agent code terminates; the CICS® system continues to initialize, but it is not known to CICSPlex SM. CICSPlex SM takes a transaction dump with a dump code of EYUK and writes a failure summary to the job log and console.

ESSS program call (PC) routine failures

If an abend occurs while a CICSPlex SM PC routine is executing, the functional recovery routine (FRR) takes an SDUMP with a title whose format is as follows:

CICSPlex SM (rrrr) Abend,(PC Set Name),(PC Routine Name),
(Job Name),(SID),(date),(time)

where:

rrrr
Is the release of CICSPlex SM
PC Set Name
Is the descriptive name of the set of PC routines that encountered the error. It can be one of:
PC Routine Name
Is the name of the PC routine within the set
Job Name
Is the MVS™ Jobname
SID
Is the MVS System ID
date
Is the date in the form MM/YY/DD
time
Is the time in the form HH:MM:SS

For each PC Set Name, the PC Routine Names are as follows:

Communication Services
Dataspace Management
Environment Services
Lock Management
MAS Assist Services

After it takes the SDUMP, the PC routine returns to its caller with a return code indicating that an abend occurred during processing.
