Segmented Monitoring to Handle Special Situations

egmented monitoring is supported by CA InterTest releases 5.1 and higher, running on z/OS systems.

Users of the following might require segmented monitoring:

• HOGAN Systems
• DCI Interface of the MSA Corporation
• LE/370 condition handlers
• Some composite programs

CA InterTest for CICS normally controls whole application programs. Segmented monitoring provides a way for CA InterTest for CICS to control only small portions (code segments) of application programs.

Use segmented monitoring sparingly for special debugging needs, such as when only certain pieces of code should be monitored because of excessive overhead or because they get control directly from programs (or interfaces) that must not be monitored by CA InterTest for CICS. The following figure shows why segmented monitoring is used.

Segmented monitoring ON and OFF options are used here:

• for a segment of code that needs testing or monitoring.
• and may not receive control in the normal way.

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. Review Notes and Warnings before using segmented monitoring.
