PCA DEVICE report SM2 reports

PCA DEVICE report

This report provides monitored data on the devices of a 3419/21 controller which have been allocated a cache.

Report output

The PCA DEVICE report is output only at the explicit request of the SM2 user with the help of the SELECT-PCA-CACHE statement (see page 174). This statement is used to output a PCA CONTROLLER report together with a PCA DEVICE report for the selected cache of a controller. The PCA DEVICE report supplies detailed information on the devices of a 3419/21 controller which have been allocated a cache.

The report can only be output if the SM2 administrator has activated the monitoring process using the statement START-MEASUREMENT-PROGRAM TYPE=*PCA.

Overflow screens may be requested for this report.

The monitored data output is sorted in accordance with the total number of access opera- tions.

It is possible to output data on up to 32 pairs of controllers and caches.
