PK80099: DFR ABENDSB78-5C UNDER Z/OS V1R8 OR LATER WITH VSM ALLOWUSERKEYCSA(NO)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a z/OS V1R8 VSM ALLOWUSERKEYCSA parameter is set, or
  defaulted in z/OS V1R9 or later, into 'NO', DFR in IMS V8, V9
  or V10 ends with an abend code SB78 RC=5C ( ABENDB78 ).
  The VSM ALLOWUSERKEYCSA (NO|YES) parameter in a DIAGxx parmlib
  member is added by z/OS V1R8.
  The default value of the VSM ALLOWUSERKEYCSA (NO|YES) parameter
  is changed into 'NO' from 'YES' by z/OS V1R9.
  'NO' prevents user key (8-F) CSA from being allocated by
  failing any attempt to obtain user key (8-F) from a CSA subpool
  (through GETMAIN or STORAGE | OBTAIN) with a B04-5C, B0A-5C, or
  B78-5C abend.
  DFR obtains the data areas in ECSA (SP=228/231) through GETMAIN
  macro with user key (8).

  If a z/OS V1R8 VSM ALLOWUSERKEYCSA parameter is set, or
  defaulted in z/OS V1R9 or later, into 'NO', DFR in IMS V8, V9
  or V10 ends with an abend code SB78 RC=5C (ABENDB78).
  The VSM ALLOWUSERKEYCSA (NO|YES) parameter in a DIAGxx parmlib
  member is added by z/OS V1R8.
  The default value of the VSM ALLOWUSERKEYCSA (NO|YES) parameter
  is changed into 'NO' from 'YES' by z/OS V1R9.
  'NO' prevents user key (8-F) CSA from being allocated by
  failing any attempt to obtain user key (8-F) from a CSA subpool
  (through GETMAIN or STORAGE | OBTAIN) with a B04-5C, B0A-5C, or
  B78-5C abend.
  DFR obtains the data areas in ECSA (SP=228/231) through GETMAIN
  macro with user key (8).
  Thus, DFR is changed so that the data areas obtained to ECSA
  (SP=228/231) are obtained to high private storage (SP=0).
  

Problem conclusion

• The following modules and macros have been modified.
  *
  * for IMS V8 or V9 (x = 8 or 9)
  DFRRSCx   - The RSCDP228 and RSCDP231 fields in "SYSTEM SECTION"
              were changed into a reserved field.
  DFRRSCDx  - This module was modified to be re-assembled to
              reflect the changes.
  DFRCTLx0 +- These modules were changed so that the data areas
  DFRIDMBx |  obtained to ECSA (SP=228 or 231) are obtained to
  DFRINTFx |  the high private storage (SP=0).
  DFRLFBFx |
  DFRNWPDx +
  DFRLPOLx  - This module was changed so that any operations are
              not processed when the RSCDPSPN is not "0."
  DFRLEQEx +- These modules were changed so that the value set to
  DFRLFCKx |  the RSCDPSPN before calling DFRLPOLx is changed into
  DFRL592x +  "0" from the RSCDP228 or RSCDP231.
  *
  * for IMS V10
  DFRRSCA   - The RSCDP228 and RSCDP231 fields in "SYSTEM SECTION"
              were changed into a reserved field.
  DFRRSCDA  - This module was modified to be re-assembled to
              reflect the changes.
  DFRCTLA0 +- These modules were changed so that the data areas
  DFRIDMBA |  obtained to ECSA (SP=228 or 231) are obtained to
  DFRINTFA |  the high private storage (SP=0).
  DFRLDBDA |
  DFRLFBFA |
  DFRNWPDA +
  DFRLPOLA  - This module was changed so that any operations are
              not processed when the RSCDPSPN is not "0."
  DFRLEQEA +- These modules were changed so that the value set to
  DFRLFCKA |  the RSCDPSPN before calling DFRLPOLA is changed into
  DFRL592A +  "0" from the RSCDP228 or RSCDP231.
  *
  DFRICTLA  - This module was changed to revise a prologue and
              comments.
