PL79393: DELETED PHASE/NODE WHILE HRETRY STILL EXECUTES ALTHOUGH IT IS NOT DISPLAYABLE BY IOF

APAR status

• Closed as suggestion for future release.

Error description

• 1) A ONE PHASE ONE FUNCTION PLAN IS SUBMITTED TO A NODE THAT
  IS IN THE DRD BUT THE VTAM LU IN THE DRD IS INCORRECT AND
      HAS NOT BEEN ACTIVATED BY VTAM. THE NODE IS DEFINED TO NDM
      AS AN INTERMEDIATE NODE.
   2) MSGNDM0086E LOGICAL UNIT IS NOT AVAILABLE.
   3) NODE IS HELD HRETRY FOR RETINT.
   4) WHILE NODE IS HELD, THE CUSTOMER DELETED THE PHASE/NODE.
      HE CHECKED THE NODE DEFINITION IN THE DRD AND SAW THE ERROR
      (THIS WAS VIA IOF).
   5) THE PHASE/NODE DISAPPEARED FROM IOF.
   6) WHEN RETINT EXPIRED, THE PHASE ATTEMPTED TO EXECUTE AS SEEN
      BY MESSAGES. IT WAS THEN HRETRY AGAIN.
   7) THIS HAPPENED REPETITIVELY UNTIL NUMBER OF RETRY'S EXPIRED.
   ***************************************************************
   ALTHOUGH THE PHASE NO LONGER DISPLAYED AFTER THE DELETE AND
   APPEARED TO BE DELETED, THERE WAS STILL AN ATTEMPT TO EXECUTE
   THE PLAN. THERE WAS NO ATTEMPT TO BROWSE THE PLAN BY GIX, SO
   I DON'T KNOW WHAT THAT WOULD HAVE SHOWN.

Comments

• APAR PL79393 HAS BEEN CLOSED AS SUG SINCE THE TCP IS WORKING
  AS DESIGNED.
  THE TROUBLE IS CAUSED BY AN ERRONEOUS NODE DEFINITION IN DRD
  LEADING THE SCHEDULED PHASE/NODE TO BE IN HRETR STATUS.
  EVEN THOUGH IT HAS BEEN CORRECTLY DELETED FROM TCF (IT IS NO
  MORE SHOWED ON IOF), THE RETRIES ARE STILL TAKING PLACE.
  THIS HAPPENS BECAUSE, AS SOON AS THE SESSION IS ACTIVATED FOR
  THAT ERRONEOUS LU (1ST TIME), THE TCP ISSUES FROM VTAM THE SAME
  RC SUCH AS THE LU IS INACTIVE CAUSING THE RETRY MECHANISM FOR
  OUR PHASE/NODE TO BE SCHEDULED.
  THE TCP IS NOT ABLE TO DISTINGUISH A NODE DEFINITION ERROR
  FROM A TEMPORARY ONE (SUCH AS THE LU INACTIVE) BECAUSE VTAM
  NOTIFIES THE SAME RC IN BOTH CASES.
  SO, ALL THE CONNECTION RETRIES ARE INEVITABLE.
