Determine Work Volume

CA SYSVIEW provides several methods to determine how well the zIIP processors are being exploited or utilized.

Note: Only SRB-mode work executing in an Enclave is eligible to run on a zIIP processor. The important or keyword here is eligible. Although SRB-mode work could be executing on an Enclave, it still not always executes on a zIIP processor.

WLM determines the work to dispatch on a zIIP processor. If a zIIP processor is not available, the work is still dispatched on a general process (CP). This process is commonly known as zIIP on CP work.

Follow these steps:

To display the current CPU configuration and usage, issue the following command:
```
CPU
```
To plot the overall use of the zIIP processors, issue the following command:
```
PLOT MVS CPU% IIP
```
To display the WLM enclaves utilizing zIIP processors, issue the following command:
```
WMENCLAV
```
To display address spaces that are using a zIIP processor, issue the following command:
```
ACTSUM
```
