OW30833: CROSS NETWORK RNAA FAILS WITH 089D0006.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Cross network RNAA fails with sense 089D0006.  VTAM requesta a
  RNAA from a gateway NCP.  The NCP returns a positive response
  to the RNAA.  VTAM then tries to SRTA the network addresses
  which fails because the network address is already in use in
  VTAM.

  * USERS AFFECTED: All VTAMs that are GW SSCPs.                 *

  * PROBLEM DESCRIPTION:   Cross network session fails with      *
  *                      089D0006 or 089D0001 after an RNAA      *
  *                      returns a network address that is       *
  *                      already in use by VTAM.                 *

  * RECOMMENDATION:                                              *
  ****************************************************************
    During cross network LU to LU session setup, a gateway SSCP
  sent an RNAA to the GateWay NCP.  The GW NCP returned a network
  address that was already in use by VTAM.  Because this could be
  a timing problem, VTAM is designed to send a NOTIFY, followed by
  another RNAA.  If the second RNAA returns a network address
  which is also in use, VTAM sets sense 089D0006 and tries to find
  a different path to the other SSCP.
    This could result in the session failing with sense 089D0006
  or 089D0001 for the other SSCP.
  

Problem conclusion

• ISTSSCKA has been enhanced to issue a new message group
  starting with IST1693I when the 089D0006 is set for the second
  RNAA.  This message group is intended to document what resource
  is trying to use the duplicate network address and what
  resource is already using it.  This information can be used
  to determine why VTAM and NCP are out of sync on their
  network address assignment.
    MSG1650, ISTINCNO, ISTCFCML, ISTCFCMM, and ISTVTMEU were
  modified to define the new MSGIST1693I.  ISTMSFLD and ISTMSFLI
  were modified to suppress the message group if the data in the
  IST1421I message is the same.
  
    The following update will be made to the VTAM Messages manual,
  GC31-8368-00 page 5-558 in V4R4:
  
  IST1693I  NETWORK ADDRESS RECEIVED FOR resourcename IN USE
  
  EXPLANATION:  This message is the first in a group of messages.
  A complete description of the message group follows.
  
     IST1693I NETWORK ADDRESS RECEIVED FOR resourcename IN USE
     IST1421I nodetype dupresource HAS DUPLICATE ADDRESS
     IST314I END
  
  IST1693I
  
      This message is issued during cross network LU-to-LU
      session setup when the network address for the specified
      resourcename could not be defined.  VTAM detected another
      resource was using the network address return by the
      gateway NCP for resourcename. The form of resourcename
      is netid.name.
  IST1421I
      nodetype is the node type of dupresource.  See Chapter 11,
      'Node and ID Types in VTAM Messages' on page 11-1 for a
      description of nodetype.
      dupresource is the name of the resource that is currently
      defined to the address in question.  The form of dupresource
      is netid.name.
  SYSTEM ACTION:  Processing continues.
  OPERATOR RESPONSE:  Issue the DISPLAY ID=dupresource,E command
  to display information about the duplicate resource.  Save the
  system log for problem determination.
  PROGRAMMER RESPONSE:  Check your network address assignments.
  See the section on non-VTAM problems, in the VTAM Diagnosis for
  additional problem determination actions.).
