Error description

• Rational Developer for System z - RDz - v9.1
  
  Enqueues are created for temporary files that are used by the
  RDz threadpools when filters are expanded.  These enqueues are
  not being cleaned up until the RDz server is recycled.
  
  These enqueues do not cause any problem.
  
  They have names such as:
  SYS1234.T1234567.RA000.RSED1859.R0100204

  ****************************************************************
  01.Exclusive enqueues on SYSDSN are created for temporary files
     that are used by the RDz thread pool processes when filters
     are expanded. These enqueues are not being cleaned up until
     the RDz server is recycled. RDz server calls DYNALLOC macro
     to allocate a temporary data set on a specific volume serial
     at first. Then it calls RDJFCB and OPEN TYPE=J to override
     the data set name with a special name for vtoc (44X'04'). As
     the default, the replaced name is witten back to the system
     JFCB but the previous temporary data set name is forgot
     without adjusting the enque status. Even if RDz server
     unallocates the file in JFCB, it is a vtoc name and the
     enque on a temporary data set remains.
  

Problem conclusion

• 01.RDz server is changed to set the bit JFCNWRIT in the
     JFCBTSDM field to 1, not to wirte back the replaced JFCB to
     the system JFCB. Though setting JFCNWRIT to replace a
     regular data set name is not recommended as documented, it
     should not cause errors for vtoc data set name.
