The segmented monitoring option is set to off by default. You can enable it with or without CNTL menu support, and with or without password protection.

Segmented monitoring should be used sparingly for special debugging needs, such as when only certain pieces of code should be monitored because of excessive overhead or to bypass automatic breakpoints that are generated when debugging an application program.

Important! Improper use of segmented monitoring options could damage your CICS system because CA InterTest for CICS places invalid machine instructions in application programs at the segmented monitoring locations specified by the user. Additional details are provided in the user guide.

The most common way to set a segmented monitoring breakpoint is through the LIST facility.

To set a location for a MON option in your source listing, enter a plus sign, +, to the left of the statement in your listing where you want monitoring to begin, and press Enter.

Likewise, to set a location for a NOM option, enter a minus sign, -, to the left of the statement in your listing where you want monitoring to stop, and press Enter. If a password is required, enter the password at the prompt.


Segmented monitoring is recommended for debugging Hogan applications.


To check the status of the segmented monitoring option on your system enter the VRPT transaction from a clear screen in CICS and press ENTER Next select 2 Global Options - Display Installation Options.

The current IN25OPTS values are displayed alphabetically. Look for the option MONOM.

The following are MONOM values:

     MENU - Segmented monitoring is enabled for all methods: Source Listing, CNTL menus, and CNTL commands.
 - Segmented monitoring is enabled for Source Listing and CNTL command methods only.
 - Segmented monitoring is disabled.

The MONOMSEC keyword option tells you if a password is required.

If MONOMSEC=YES, you need the password to set MON or NOM using any method.

Changing the IN25OPTS configuration parameters is outlined in the Installation guide.

Once you change the desired option you will need to assemble and relink the IN25OPTS load module.

CA InterTest for CICS has to be stopped and restarted for any new options to take effect. The installation guide outlines these steps.
