OW05287: THE V NET,XXX,UPDATE=ALL WAS ISSUED TO CHANGE THE IDNUM BUT THE UPDATE WAS NOT PERFORMED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• V NET,xxx,UPDATE=ALL was issued to change the IDNUM on a
  switched major node. The command executed ok but the update
  was not done. This resulted in ABEND0C4 in ISTACCQ3 at
  offset X'27A2' level UY91902. During recreation the
  UPDATE=ALL continued to fail but the subsequent abend was
  not seen.

  An attempt was made to change IDNUM using the enhanced
  dynamic reconfiguration introduced in V4R1 by changing the
  value of IDNUM on a PU in a switched major node and issuing
  the V NET,ACT,ID=swmajnode,UPDATE=ALL command. There were no
  error messages issued. However, when a dial-in connection
  was attempted using the OLD station ID (IDBLK/IDNUM), ABEND0C4
  in ISTACCQ3 at X'27A2' occurred.
  
  ISTSDCDR, in doing the dynamic change, put the new station ID
  in the PU's RDTE, but it was not SRTADDed and the original
  station ID, which was SRTADDed when the major node was
  originally activated, was not SRTDELed. The switched major node
  was then inactivated, freeing the RDTE storage. When a REQUEST
  CONTACT (REQCONT) came in with the original station ID, a
  SRTFIND was done for that station ID and it was found since it
  never got deleted. The entry that was found still pointed to
  the RDTE that had since been freed. That storage no longer
  belonged to VTAM so an ABEND0C4 occurred.
  
  An additional symptom is that an attempt to establish a dial-in
  connection using the new station ID fails with MSGIST690I and
  MSGIST081I:
    IST690I CONNECTION REQUEST DENIED - INVALID STATION ID
    IST081I LINE NAME = xxxxx LINE GROUP = yyyyy MAJNOD = zzzzz
  because the new station ID was never SRTADDed.
  

Problem conclusion

• ISTSDCDR has been changed to SRTDEL the old station ID and
  SRTADD the new station ID when IDBLK or IDNUM are changed
  with enhanced dynamic reconfiguration. If the new station
  ID is the same as one already in the network, the V NET,ACT,
  ID=swmajnode,UPDATE=ALL command will fail with MSGIST886I
  and MSGIST523I:
    IST886I VARY ACT swmajnode CHANGE puname FAILED
    IST523I REASON = DUPLICATE STATION ID
  
  VTAM V4R2 Messages and Codes (SC31-6493-0) will be changed on
  page 5-231 under message IST886I for the VARY ACT command to
  add the following new reason value for message IST523I:
    DUPLICATE STATION ID
      An attempt was made to perform a DR CHANGE of IDBLK or
      IDNUM for a switched PU, but the resulting Station ID was
      not unique in the network.
