OA50436: ABEND 0C4 PIC 11 IN IDA019RP AFTER GOING THROUGH DYNAMIC BUFFER ADDITION FOR A DATA SET OPENED IN LSR MODE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An abend 0C4 Pic 11 can occur after adding buffers to a data set
  opened in LSR Mode. z/OS 2.2 will attempt to add buffers to an
  LSR Pool if there are insufficient buffers. During this process
  after adding buffers VSAM will attempt to update the RPL
  feedback code to indicate to the caller that buffers were
  added.
  In the reported case VSAM had added buffers and was attempting
  to update the RPL feedback to indicate this. However the
  register used to point to the RPL had previously been used to
  point to storage to be freemained, so when VSAM attempted to
  update the RPL feedback code an abend 0C4 pic 11 occurred.
  

Local fix

• Specify sufficient LSR buffers so that Dynamic Buffer Addition
  is not attempted.

  ****************************************************************
  WHEN INSUFFICIENT BUFFERS EXIST IN A LSR POOL TO SATISFY A
  REQUEST DYNAMIC BUFFER ADDITION ADDS MORE BUFFERS TO THE POOL. A
  RPLERRCD IS SET TO INFORM THE CALLER DYNAMIC BUFFER ADDITION HAS
  OCCURRED.  AN ABEND0C4 OR ONE WORD OVERLAY MAY OCCUR WHEN
  SETTING RPLERRCD AS THE POINTER TO THE RPL IS NOT PROPERLY SET.
  

Problem conclusion

• MODULE IDA019RP IS CHANGED TO CORRECTLY POINT TO THE RPL WHEN
  SETTING RPLERRCD.
