PM89597: ADVANCED ACBGEN TURNS ON DXSECTAB EXISTS BIT OF PSB INCORRECTLY WHEN DFS0587I BUILD ERROR OCCURS FOR THE PRECEDING PSB

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When LIU Advanced ACBGEN run and all of the following conditions
  met, DXSECTAB EXISTS bit of the PSB which was built by condition
  (4) is turned on incorrectly.
  
   (1) IMS V12 with APAR PM42909 applied or IMS V13 is used.
   (2) LIU V2R1 with APAR PM61228 applied is used.
   (3) Advanced ACBGEN fails to build PSB with DB type PCB and
  DFS0587I is issued.
   (4) Just after the DFS0587I, Advanced ACBGEN succeeds to build
  PSB without DB type PCB.
  
  If the IMS Catalog population utility processes the PSB which
  was built by condition (4), it causes the ABENDS0C4 error by
  using the incorrect bit.

    PROBLEM DESCRIPTION: When LIU Advanced ACBGEN runs and all
                         of the following conditions met,
                         DXSECTAB EXISTS bit in a directory
                         entry of a PSB which was built by the
                         condition (3  will be turned on
                         incorrectly.
  
                          (1  IMS V12 with APAR PM42909 applied
                              or IMS V13 is used.
                          (2  Advanced ACBGEN fails to build a
                              PSB with any DB type PCBs and
                              DFS0587I is issued.
                          (3  Just after the DFS0587I, Advanced
                              ACBGEN succeeds to build a PSB
                              without DB type PCB.
  
                         If the IMS Catalog population utility
                         processes the PSB which was built by
                         condition (3 , it can cause the
                         ABENDS0C4 error by using the incorrect
                         bit.
  
    RECOMMENDATION: Apply the maintenance for this APAR.
  
  Advanced ACBGEN should clear an internal flag introduced by IMS
  V12 APAR PM42909 which indicates the PSB has DB type PCBs, but
  the flag is not cleared when a build error of the PSB with DB
  type PCBs occurs and DFS0587I is issued.
  
  After the error occurred, if the next PSB member to be processed
  doesn't have DB type PCBs, this wrong flag is used and a wrong
  directory entry is created for the PSB.
  
  If the IMS Catalog population utility processes the PSB with
  the wrong directory entry, it can cause the ABENDS0C4 error.
  
  Advanced ACBGEN is fixed to clear the internal flag correctly
  when a build error DFS0587I occurs. Then the directory entry
  for the PSB without DB type PCBs will be corrected.
