APAR status

  • Closed as program error.

Error description

  • When attempting to reestablish a dependent LU session, a race
    condition occurs when both session partners attempts to initiate
    a session request. This results in the BIND being rejected with
    sense 0835004B due to the presence of unexpected URC data.
    

Local fix

  • Contact US Level/2 support for efix.
    

Problem summary

  • The problem is triggered by a race from both ends of the session
    attempting to initiate a session at the same time.  VTAM is
    attempting an Initiate Other and CSAIX is attempting an initiate
    request via an INITSELF.  Depending on which Bind arrives
    first, the session may be rejected due to no URC data in the
    BIND request.
    

Problem conclusion

  • Code has been changed to modify the format of the INITSELF
    request to avoid this race condition.
