  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  CONTINUOUS DATA COLLECTION (CDC)

  CDC Routed Entries per Sec is always zero with PJ32427 applied

  COMMENTS:
  The Cointinuous Data Collection (CDC) Routed Entries per Sec
  value reported in the Tivoli Monitor Agent for z/TPF I-Stream
  attribute group always displays zeros. The cause of the zeros
  is an incorrect MVC instruction in source file cdcist.asm
  causing data to be retreived from address 4.
  

Problem conclusion

• SOLUTION:
  The MVC is fixed to correctly collect routed entries from 0 off
  regsiter 4. The CDC value is now correct and the Tivoli display
  is no longer always zeros.
  
  An additional change is being made. On ZCDCO STOP message
  CDCO0067E - CONTINUOUS DATA COLLECTION UNABLE TO RELEASE
  STORAGE is being removed. Message CDCO0067E happens when
  tpf_rsysc() gives an error return. In this case tpf_rsysc()
  uses a unique token identifier. The only possible error is that
  the unique token identifier does not exist. This means that
  either the system heap was never obtained or another process
  previously released the system heap. If either case happens, it
  is not an error. The end result is that at the end of ZCDCO
  STOP the system heap used for CDC is no longer used.
  
  COREQS: NO
  None.
  
  MIGRATION CONSIDERATIONS: NO
  None.
