    ****************************************************************
    The problem may be summarized as follows:
    
    1. A Telnet server was configured with takeover specified,
       for example:
    
       TKOGENLU 5
    
    2. A client connection was successfully started with the Telnet
       server.  A second client connection was then attempted,
       and generic takeover was attempted.  After 5 seconds, the
       takeover attempt failed and a different LU was assigned
       to the new connection:
    
       EZZ6035I TN3270 DEBUG CONN   DETAIL 901
         IP..PORT: x.xx.xxx.xx..1745
         CONN: 00000135  LU: TCPM1151 MOD: EZBTDALU
         RCODE: 1009-00  Takeover has failed.
         PARM1: 00000000 PARM2: 00000000 PARM3: TKOGENLU
       EZZ6034I TN3270 CONN 00000135 LU TCPM1152 NEGOTIATED TN3270E
         IP..PORT: x.xx.xxx.xx..1745
    
    3. An object display command was issued:
    
       D TCPIP,TN3270,OBJ,TYPE=LUGRP
    
       Output from the display contained an incorrect connection
       count for the associated LU group.

Problem conclusion

  • Modules EZBTDALU and EZBTPGLU have been amended to
    to correctly reset CVB based CLID pointers for
    Telnet takeover.
    
    Module EZBTPTKO has been included for maintenance
    purposes only.
