OA01622: IEF211I DATA SET RESERVATION UNSUCCESSFUL

APAR status

• Closed as fixed if next.

Error description

• Job that uses GDG data set fails with msgIEF211I DATA SET
  RESERVATION UNSUCCESSFUL.
  
  For example:
    While JOB1 was running,
     //stepname EXEC PGM=pgmname
     //ddname   DD DSN='DSN.STL(0)',DISP=OLD
        (notice that the above DSN is in quotes)
  
    JOB2 got IEF211I.
     //stepname EXEC PGM=COD0220
     //ddname   DD  DSN=DSN.STL(0),DISP=SHR
        (notice that the above DSN is NOT in quotes)
  ==> IEF211I JOB2 stepname ddname - DATA SET RESERVATION
                                     UNSUCCESSFUL.
      IEF272I JOB2 stepname - STEP WAS NOT EXECUTED.
  
  JOB1 issues ENQs for:
            DSN.STL(0)       - because the DSN is in quotes
  and also for (e.g.)
            DSN.STL.G0001V00
  
  JOB2 issues ENQs for:
            DSN.STL
  and also for (e.g.)
            DSN.STL.G0001V00
  
  Both JOB1 and JOB2 will attempt to use (e.g.) DSN.STL.G0001V00,
  but JOB1 should REALLY attempt to use DSN.STL(0) -- which most
  likely does not exist.
  
       If a relative generation name is enclosed in apostrophes
              e.g.  'gdgname(0)'
  an ENQ is properly issued on that exact dataset name at job
  initiation time.  But then at step allocation time the DSN is
  treated as if it were NOT in apostrophes, the relative GDG name
  is expanded to an absolute GDG name, and an ENQ is issued for
  that fully-qualified G0000V00 name.
       A relative GDG name in quotes should NOT be treated as a
  generation dataset (GDS) and an ENQ for the fully-qualified
  G0000V00 should NOT be issued.
  
  Additional Keywords:
       apostrophe quote enqueue
