IBM Session Manager Implementation

80 IBM Session Manager Implementation

named ISZE21GA and is supplied in the SISZEXIT dataset. Specific details

outlining the necessary steps to use the ISZE21GA exit are given in Chapter 22,

“Parallel Sysplex® Support,” of the Session Manager for z/OS Facilities manual

SC34-6287-04.

3.9 E22 - Signon completion

This exit point is invoked when the user has finally been identified and the

signon, or reconnection, has been accepted. The autoselect session detail

number may be modified by the exit. The E22 exit might also be used to record

the fact that the signon has been accepted. A message may be sent to the log

and to the terminal. For Session Manager 1.1.05 and later, this exit point is used

to provide the dynamic menus facility. If the E22 exit point is used in conjunction

with the signoff exit point (E29), a table or file may be maintained recording the

signon and signoff times of each user. This may then be used for accounting

purposes.

3.10 E25 - Input 3270 datastream exit

The new function APAR PQ89033 added support for the E25 input exit. It is

invoked upon receipt of a terminal input 3270 datastream, prior to Session

Manager escape sequence detection and processing. Chapter 16 of the Session

Manager for z/OS Facilities Reference, SC34-6287, should be reviewed prior to

using this exit, as it can result in increased CPU or other performance problems.

3.11 E29 - Logoff or disconnect from Session Manager

This exit point is invoked when the DISCONNECT or LOGOFF command is used

to disconnect from Session Manager. It is also invoked when a user is

disconnected or logged off from Session Manager due to expiry of the idle time

interval, and also when Session Manager encounters an irrecoverable terminal

error. As with the Signon exit point, a message may be sent to the log. The

signoff event may be recorded in a table or file, and if the signon time has also

been recorded, the interval may be used for accounting purposes.

3.12 E31 - Slave session pre-initiation

This exit point is called immediately prior to the initiation of an application

session; that is, when a user selects an application from a Menu panel. The main
