IKJEFLN2 is a TSO/E Post-Display Exit which allows TSO users to reconnect to their own TSO session, or cancel it. The exit also has the capability to automatically unlock a TSO session awaiting operator intervention, for example by replying CANCEL to an outstanding allocation recovery message.

Although this product was originally designed for users who connect to TSO/E via TCP/IP using the TN3270 protocol, it is equally useful to TSO/E users who connect directly to VTAM, using either SNA or non-SNA terminals.

The exit must be installed on the system on which both the TSO session and the TN3270 server are active, and the user must select the Reconnect option with an S on the TSO/E LOGON panel. When all of these conditions are met, the user receives the screen shown below instead of the otherwise expected IKJ56425I LOGON rejected, UserId user_id already logged on, IKJ606I TSOLOGON REJECTED. USERID user_id IN USE or IKJ56411I TSOLOGON RECONNECT REJECTED - USERID user_id IN USE messages.

 Enter C to cancel the existing TSO session or R to reconnect ===> _   

The user can reply C to cancel the session, R to reconnect or X to exit.

The IKJEFLN2 exit looks for an outstanding IEF238D allocation recovery message that may have caused the existing TSO session to lock up. If such a condition exists, IKJEFLN2 attempts to automatically unlock the session by replying CANCEL to the message.

The IKJEFLN2 exit supports all MVS systems at the OS/390 R4 level and above. To install the IKJEFLN2 exit, copy the load-module into an authorised system library and refresh LLA. To uninstall, simply delete the load-module and refresh LLA.
