Changing or displaying the status of WTO installation exit IEAVMXIT

Use the CONTROL M,UEXIT command to change or display the status of the WTO installation exit IEAVMXIT. This exit receives control when the system issues a WTO message unless your installation names another WTO installation exit routine for the message. To learn what messages are currently processed by IEAVMXIT, issue the DISPLAY MPF command.

The UEXIT parameter on the INIT statement in the CONSOLxx parmlib member controls whether IEAVMXIT is active at IPL. If the UEXIT parameter is not coded, IEAVMXIT will be activated, if it is installed. If IEAVMXIT is not installed, the system will IPL with UEXIT=N.

The syntax of the command is:

 
K M[,UEXIT={Y|N}]
    |,REF

The parameters are:

UEXIT=

The status of the general WTO installation exit IEAVMXIT is to be changed.

Y: The general user exit routine IEAVMXIT is to become active. If IEAVMXIT is already active and you want a new copy, deactivate IEAVMXIT, refresh the library lookaside (LLA), and then reactivate IEAVMXIT.
N: The general user exit routine IEAVMXIT is to become inactive.

REF

Displays the current values of all the operands on the K M command.

Example 1:

To activate the general WTO installation exit routine IEAVMXIT, enter:

K M,UEXIT=Y

Example 2:

To load a new copy of the general WTO installation-exit routine IEAVMXIT, first enter:

K M,UEXIT=N

to deactivate the current copy. Then enter:

MODIFY LLA,REFRESH

After you receive notification that the library lookaside (LLA) is refreshed, enter:

K M,UEXIT=Y

to activate the new copy.
