Advanced Demo Session › Option 02: Limit CICS Storage and Requests › Remove the MXR Option

Remove the MXR Option

Now you can remove the MXR option so that ASMDEMO continues executing. If this were your own program, you would want to examine the instructions that are generating excessive CICS requests.

1. Type status in the Command field and press Enter (or press PF12).

   CA InterTest for CICS displays the Monitoring Status display.

2. To remove an option, tab to the Option, enter an r, and press Enter.

   Note: Only remove the MXR option; do not remove or modify the MXS option.

3. Tab to the MXR entry.
4. Type R.
5. Press Enter.

   CA InterTest for CICS removes the MXR option.

6. Press PF3 to return to the Source Listing Breakpoint screen.

   Notice that the explanation of the abend does not redisplay so that more of your source listing can be displayed.

Limit Storage Acquisition

1. Press PF5 to resume program execution.

   The next screen you see is an automatic breakpoint display. CA InterTest for CICS halted ASMDEMO at an automatic breakpoint because the maximum main storage limit of 50,000 was exceeded.

   Note: In most cases, the instruction that triggered the automatic breakpoint is within a loop containing a GETMAIN request.
