Error description

  • Error Description￘
    When logging in to a 3270 application over an LU type 2
    session, the login is rejected with sense code 0805000B
    indicating that the LU is already in session.
    
    Additional symptoms:
    When a takeover occurs the DLUS does not have session routing
    information to send an UNBIND when the DLUR ends the session.
    VTAM will send a DACTLU Normal but the DLUR does not send UNBIND
    to the PLU host to end the session.
    

Local fix

  • Local Fix￘
    Stop/restart the PU.
    

Problem summary

  • USERS AFFECTED: All users of DLUR PUs.
    
    PROBLEM DESCRIPTION:
    When logging in to a 3270 application over an LU type 2 session,
    the login is rejected with sense code 0805000B indicating that
    the LU is already in session.
    
    PROBLEM SUMMARY:
    If a tn3270 client user connected to an LU owned by a DLUR PU
    logs off from the SSCP screen after issuing a <SYSREQ> key, then
    it is possible for the mainframe to fail to terminate the
    session correctly. If DACTLU/ACTLU is issued, but the PLU does
    not send an UNBIND, the tn3270 client is disconnected and
    Communication Server marks the LU-LU session as terminated.
    Subsequent attempts to log on to the LU fail with text
    indicating sense code 0805000B because the mainframe application
    on the PLU still thinks the session is active.
    

Problem conclusion

  • Communication Server has been modified to send an UNBIND type
    0x09 (Hierarchical reset) to the PLU when a normal (as opposed
    to SON) DACTLU is received when the LU-LU session is active for
    a DLUR LU.
    
    The problem can be avoided without this fix by using the node
    PTF flag DLUR_UNBIND_ON_DACTLU.
    

Temporary fix

  •  Drivero.
