PK72688: AFTER AN IMS SHUTDOWN /CHE PURGE, IQCSELCT FAILS WITH CC=08 AND MSGIEC130I WHEN USING CHKPT LAST TO REQUEUE MESSAGES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Upon IMS shutdown with a /CHE PURGE and an IMS cold start,
  running IQCSELCT to requeue messages fails when using the CHKPT
  LAST command format.  With a prior IMS /CHE DUMPQ all works as
  expected. In the failing case, QCF is not finding the start
  checkpoint and as a result is getting CC=08 and informational
  message IEC130I is also received:
  IEC130I LOGIN    DD STATEMENT MISSING
  
  Comment (added 9-14-10):
  As a result of this APAR, QCF code was added to check for
  consecutive log records.  This includes:
   - each next log record to have LSN greater than the previous.
   - each next log record to have a timestamp greater than
     the previous.
  If the log records are not consecutive, read log stops and
  select ends with RC=08 along with the following error message
  being received:  IQC3025E Base CheckPoint not found
  
  APAR PM22530 was created to provide a new error message in
  such rare case of this encounter.
