CICS® does not provide identical support for resources and
functions across all of its platforms or releases. For example, a resource,
such as FEPI, that is supported in the CICS TS environment might not be supported
on other platforms. Similarly, the amount or type of data available for a
resource can vary among CICS platforms and releases. These variations in support pose a special challenge to CICSPlex® SM, which
offers a SSI of multiple and varied CICS systems.
Here are some examples that illustrate how CICSPlex SM handles
variations in support for resources and functions throughout a CICSplex that
includes CICS TS.systems.
You create a monitor definition for transient data queues, add it to a monitor group, and associate the monitor group with a monitor specification. The scope of the monitor specification is every CICS system in the CICSplex. As each CICS system starts, CICSPlex SM determines whether it can install the monitor definition in that system. If not, CICSPlex SM issues a message to inform you that the monitor definition could not be installed. Both the monitor function and transient data queue resources are supported under CICS TS, so CICSPlex SM installs the monitor definition in those environments and monitoring begins.
You create an evaluation definition and name MPROGRAM (monitored programs) as the resource
to be evaluated by CICSPlex SM’s RTA function. The evaluation definition is named in
an analysis definition, which is linked, via an analysis group, to an analysis specification. The scope
of the analysis specification is every CICS system in the CICSplex. The analysis definition is
installed in the CICS TS systems. If an analysis definition names multiple evaluation definitions, CICSPlex SM installs
those that are supported in the target environment.
In summary, if you request a function that isn’t available in a particular CICS environment, CICSPlex SM issues a warning message. You do not have to respond to the message and, more importantly, you do not have to take variations in support into account when creating CICSPlex SM object definitions: you should always consider CICSPlex SM object definitions to be reusable.
