PI67032: DFHSM0131 CICS IS UNDER STRESS (SHORT ON STORAGE BELOW 16MB)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CJSA transaction (running program DFHSJTHP) causes
  SOS in UDSA.
  The resource defintions show that program DFHSJTHP
  is defined with DAtalocation: Below.
  The DATALOCATION for DFHSJTHP was not explicitly specified
  because this is a program definition for a Java program.
  The storage actually used by the Java code will be
  31 or 64 bit. The JCICS GET CONTAINER call issues
  an EXEC CICS GET CONTAINER SET call.  This will return the
  SET area using the program's DATALOCATION and so that
  gives 24 bit storage. There is no way to request that
  the SET storage get released so it builds up until CICS
  goes SOS below the line.
  

Local fix

• Change the DAtalocation in program DFHSJTHP to ANY

  ****************************************************************
  Program DFHSJTHP is defined with DATALOCATION(BELOW). The
  Liberty application calls JCICS GET CONTAINER to get the
  container data. The JCICS GET CONTAINER call issues an EXEC
  CICS GET CONTAINER SET call which will return the SET area
  using program DFHSJTHP DATALOCATION. So 24 bit storage is
  allocated. When lots of containers are being accessed from
  application, lots of 24-bit storage will be allocated causing
  CICS SOS below the line.
  

Problem conclusion

• The definition of PROGRAM(DFHSJTHP) has been updated to specify
  DATALOCATION(ANY).
