PK78241: MSGDFS3213I AFTER /RST LINK COMMAND INDICATING REMOTE INITIATED LINK START FAILED WITH RC=04 BECAUSE INITIATOR NODE IS USERVAR.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MSC session initiation (/RST LINK) fails with error messages
  DFS3213 and DFS3672 because IMS cannot find an MSC NODE name
  that matches the PLU name passed by VTAM when the SCIP exit is
  driven. The PLU name passed is the USERVAR rather than the real
  name. VTAM APAR OA20677 changed the way VTAM handles USERVARs.
  If a USERVAR is defined in VTAM it will be passed when the SCIP
  exit is driven. Before the APAR the real PLU name (APPLID) was
  passed.
  The messages issued when the SCIP exit is driven:
  DFS3213I 9:29:12 REMOTE INITIATED LINK START FAILED, REASON
   CODE=04. PARTNER ID DW. INITIATOR IS NODE I66X.
  DFS3672I 9:29:12 SESSION ERROR. TYPE=SCP CODE=34 QUAL.=04
   MSG=3213.
  In this case, I66X is the USERVAR and cannot be found in a
  search of MSC NODE names which are usually APPLIDs so the link
  start attempt is rejected.

  After applying VTAM APAR OA20677 which changes the way VTAM
  handles USERVARS for LU6.1 sessions, MSC VTAM links and ISC
  static nodes fail when they are started. ISC ETO nodes may fail
  too if they don't recognize the PLU symbolic USERVAR name.
  This VTAM APAR changed the PLUNAME in the bind image pointed
  to by word 4 in the SCIP exit input parameter list to the
  USERVAR name instead of the primary's APPLID name. The IMS
  SCIP exit bind processing searched for the LUNAME using the
  primary's APPLID name. This causes the PLUNAME to not be
  recognized and the bind is rejected.
  
  IMS XRF was not being used but the USERVAR names were set using
  the VTAM command F IMSVTAM,USERVAR.

Problem conclusion

• AIDS: RIDS/DCS RIDS/CNTRL DCS CNTRL
   GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  The IMS SCIP exit in module DFSCNXA0 was changed to search
  for a matching control block (LLB for MSC link and VTCB for
  ISC node) using the symbolic USERVAR name first, then the
  PLU APPLID name second, and if either is found, the bind is
  accepted.
  
  Publication Changes:
  Messages and Codes Vol 1 manual ( GC18-9712-01 ) will be
  changed for message DFS3213I reason code 04 to add:
  
  04 - The Partner ID specified does not exist on this system or
  the logical link for NODENAME = nodename could not be found.
