System availability monitoring

With system availability monitoring (SAM), you can be notified if a CICS® system is not active at any point during its expected hours of operation. You can also be notified if any of the following conditions should start or stop:

If the CICS system becomes unavailable, or if one of the above conditions occurs, a severity level is assigned and the appropriate CICSPlex SM messages are issued. These messages, which are prefixed with EYUPN, are described in the CICSPlex SM Messages and Codes book.

Default notification values

This section describes the default severity levels and actions associated with each condition for which system availability monitoring produces a notification.

Activating system availability monitoring

Depending on the level of system availability monitoring you want to activate, you can perform either or both of the following actions:

If any of the severity levels or actions shown in Default notification values is not appropriate for your use, you can change it for a specific CICS system using the CICSSYS or MAS view. If you want the new default to apply to multiple CICS systems, you can, instead, modify the analysis specification with which the CICS systems are associated.

As illustrated in the example shown in Figure 1, you can implement system availability monitoring by simply modifying the appropriate CICSPlex SM definition of a CICS system.

Figure 1. System availability monitoring
 The diagram shows an example of system availability monitoring.. Two MVS systems, System A and System B are shown. System A has a CMAS, EYUCMS1A and four MASs, EYUMAS1A (a TOR), EYUMAS2A (an AOR), EYUMAS3A (an AOR) and EYUMAS4A (a FOR). System B has a CMAS, EYUCMS1B and a MAS, EYUMAS1B (an AOR). Sysplex EYUPLX01 contains all the MASs from both systems. System Group EYUCSG01 contains all three AORs (across both systems) and the FOR.. EYUMAS1B is also contained in system group, EYUCSG05. EYUCMS1A is the maintenance point for CICSplex EYUPLX01. There is a connection between the two CMASs. The definitions in the data repository are described in the text following the picture.

In this example, the definition of the CICS system named EYUMAS1A shows that:

This example also illustrates how other predefined conditions might be handled:
