IV40890: SENSE 0805000B RECEIVED WHEN LOGGING IN TO 3270 APPLICATION
A fix is available
Closed as program error.
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￘ Stop/restart the PU.
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.
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.
