PK22246: ABEND S0C4 DURING PROGRAM ALAGEN1 DUE TO EXCESSIVE LOG DATA TRACKED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When massive amounts of log data are tracked and stored
  internally (approx. 15 million UNDO/REDO log records), a storage
  overlay is possible causing the ABEND S0C4 either in csect
  ALAGEN1 or ALASUBG (both during general report processing). This
  APAR addresses both an increase in the size of this failing
  storage area and an appropriate error message (rather than an
  ABEND S0C4) in cases where the size is still exceeded.
  
  OTHER KEYWORDS: ABEND0C4 0C4 S0C4
  

Local fix

• As the fix will not allow more processing, alternative solutions
  are:
  * run for shorter time period and
  * provide more filtering.
