+=============================================================================+

If you further specify other exception criteria when you use AUTO, EPILOG displays the resource panel(s) for those other criteria, even if they do not reflect the most significant bottleneck.

The AUTO keyword is valid only when you request a DETAILed degradation display.

The default A-matrix (called DEFAULT) selects the associated resource panels. You can override this by using the AMATRIX keyword plus AUTO. In the example below, EPILOG uses the A-matrix called MYMAT instead of DEFAULT to make its decisions:

DISPLAY GRP(2) TODAY AUTO AMATRIX(MYMAT)

A-Matrix utilities

A-matrices are simply standard members of the RKANPAR partitioned dataset, so they can be added, deleted, or edited as normal PDS members. EPILOG also provides a set of commands to create, delete, list, and replace A-matrix tables.

Create an A-matrix (CREATEM command)

The CREATEM command (or CMAT) creates a new automatic analysis member. The first argument, which is required, is a 17 character A-matrix name. You can also enter any number of wait reasons, each followed by the resource panel names which are to be associated with it. The syntax of the CREATEM command is:

CMAT A-matrix-name wait-reason(resource-panels ...) ...

For example, the following command creates a new A-matrix called SHIFT1, which displays the RCPU, RDEV, and RSAP resource panels whenever using CPU in IMS is the most significant wait reason:

CMAT SHIFT1 IMS(RCPU RDEV RSAP)
