OA51110: LMMDEL FAILS TO DELETE MEMBER GENERATIONS, WHEN THE DATA ID IS DEFINED BY LMINIT USING DDNAME.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If you use the LMINIT service to allocate a PDSE V2 data set
  configured for member generations, then use the LMMDEL service
  to delete a member, the member does not actually get deleted.
  If you use edit to create a new member with the same name, the
  previous member is stored as generation -1.
  
  The same problem occurs with the LMMREN service. If you attempt
  to rename a member using the LMMREN service, the original still
  exists.  If you then try to create a new member with the same
  name, the original member is stored as generation -1.

  If the LMINIT is done using the DDNAME parameter, the PDSE
  version and number of generations values are not initialized
  when ISPCST is called.
  

Problem conclusion

• ISPCST is modified to call CST_DELETE_GEN when uninitialized
  values are found for the PDSE version and the number of
  generations.  CST_DELETE_GEN already contains logic to set the
  PDSE version and number of generations values and proceed
  accordingly.
