OA53728: ABEND C0D DURING DELETE OF A VSAM LSR POOL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a VSAM LSR Pool is deleted, VSAM will free various control
  blocks and if they are page fixed it will issue a PGSER RELEASE
  
  In the reported case a data set that was open in LSR mode was
  being closed and the PGSER RELEASE was issued with a very large
  range - (X'00000000' to X'7C03FFFF'). This resulted in the abend
  COD and a spin loop.
  
  Other symptoms are 0C4 abends in csect IDA0192Y in load module
  IDA0192A when attempting to free storage. And ABEND073 RC24
  after a SETLOCK OBTAIN for RSMC in IAXPP when doing a PGSER
  RELEASE.
  
  Additional symptoms:
  CICS jobs fail with ABEND 071- excessive spin loops
  reported by message:
  DFHKE0997 DFHKESTX DRIVEN FOR CLEANUP ON AN ESSENTIAL TCB WITH
            COMPLETION CODE 00071000. UNABLE TO RECOVER.
  DFHKE0201 ABOUT TO TAKE SDUMP. DUMPCODE: KERNDUMP,
            DUMPID: 0/0000. (MODULE DFHKESTX).
  CICS is closing a file at the time of this error.
  USER'S AFFECTED: This problem affects any users of LSR pools
  that specify hiperspace buffers.  This includes users of SMB
  (System managed buffering) who specify hiperspace weighted,
  SMBHWT.

Local fix

• Remove the PTFs for OA50752 if possible. These are UA92659
  UA92660
  
  Or
  
  Remove Hiperspace Buffers from those applications that use
  VSAM LSR with Hiperspace buffers.(Sometimes you will see
  HBUFNI=  or HBUFND=  in the AMP keyword or the SUBSYS
  keyword on the DD card for the cluster in the job. Remove
  HBUFNI and HBUFND, hiperspace buffers). Other users of
  hiperspace buffers include IMS and CICS and VSAM System Managed
  Buffering (SMB).
  
  Or
  
  Install ++apar or PTFs for OA53728 when available
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of VSAM LSR pools with hiperspace  *
  *                 buffers who have PTFs for OA50752 applied    *
  *                 (UA92659 and UA92660).                       *
  ****************************************************************
  * PROBLEM DESCRIPTION: Various abends can occur during BLDVRP  *
  *                      or DLVRP if using hiperspace buffers.   *
  ****************************************************************
  * RECOMMENDATION: Apply PTFs.                                  *
  ****************************************************************
  The building of hiperspace buffers in an LSR (Local Shared
  Resources) buffer pool can corrupt the resource table and cause
  abends either during clean up of a build or during deletion of
  the pool.
  

Problem conclusion

• Logic for hiperspace buffers has been corrected to add to the
  resource table correctly.
