Problem summary

  • APAR NUMBER:  PJ41039
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  CONTINUOUS DATA COLLECTION (CDC)
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    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.
