System Request

To prevent specific users from seeing the System Request menu, specify: GRTOBJAUT OBJ(QSYS/QGMNSYSR)OBJTYPE(*PNLGRP)  

USER(USERA)AUT(*EXCLUDE)

A user can use the system request function to suspend the current job and display the System Request Menu. The System Request Menu allows the user to send and display messages, transfer to a second job, or end the current job. This might represent a security exposure because the public authority to the System Request Menu is *USE when a system is shipped.

To call up the System Request menu:

1.Press the Sys Req key to show key an input line at the bottom of the display.

2.Press Enter to show the System Request Menu.

Each time the System Request key is pressed, the system automatically changes the current user profile of the job to the initial user profile of the job. This is done so that the user does not have any additional authority on the System Request menu or in the Presystem Request Program exit program. After the System Request function is completed, the current user profile of the job is returned to the value that it was before the System Request key was pressed.
