The VM Server Coding the Installation Exit

The Installation Exit gives a site the opportunity to alter the processing of key activities on the server machine. The Installation Exit program TSSINS is included as part of the server machine load deck during the server machine nucleus generation. Invoking the exit, once it has been installed, is controlled through the EXIT(ON|OFF) control option.

Control is passed to the Installation Exit at the following points:

• Directory post validation
• Message processing
• Minidisk post validation
• Password change
• Password phrase change
• Post-initiation
• Pre-initiation
• Resource access verification
• Resource post validation
• Security File change
• Session termination
• TSS command invocation
• Undefined user initiation
• Violation processing

In most cases, the exit program has the option of terminating the request, allowing the request to continue as is, altering the request, or bypassing security for the request.
