This field is always present for each registered member, and represents the desirability of the system owning the member, relative to the other systems in the sysplex or subplex (system weight), or a measure of how well the individual application is meeting its WLM policies (server-specific weight). Like the Communications Server weight and net weight, a higher value means it is more desirable. WLM weights can be in the range 0 – 64. The WLM weight is used as a key component of the net weight. The WLM weight is the composite weight, and is the sum of the modified CP, zAAP, and zIIP weights displayed on the next line. Line 10 in Figure 1 is one of many lines that contain the WLM WEIGHT field, and Lines 10a and 10b are some of the many lines that contain the modified CP, zAAP, and zIIP weights described in Table 1.
| Processor | DISTMETHOD BASEWLM | DISTMETHOD SERVERWLM |
|---|---|---|
| CP | The first value is the WLM system general CP
weight recommendation. It is based on the amount of displaceable general
CPU capacity on this system, as compared to the other target systems. The second value is the first value modified by the expected general CP usage proportion configured on the PORTLIST and WLM statement for this application. |
The first value is the WLM server-specific general
CP recommendation. This is the amount of displaceable general CPU
capacity, based on the application workload's importance (as defined
by the WLM policy) as compared to the other target systems. The second value is the first value modified by the proportion of general CP capacity that is currently being consumed by the application's workload, as compared to the other processors (zAAP and zIIP). |
| zAAP | The first value is the WLM system zAAP weight
recommendation. It is based on the amount of displaceable zAAP capacity
on this system, as compared to the other target systems. The second value is the first value modified by the expected zAAP usage proportion configured on the PORTLIST and WLM statement for this application. |
The first value is the WLM server-specific zAAP
recommendation. This is the amount of displaceable zAAP capacity,
based on the importance (as defined by the WLM policy) of the application's
workload, as compared to the other target systems. The second value is the first value modified by the proportion of zAAP capacity that is currently being consumed by the application's workload, as compared to the other processors (general CPU and zIIP). |
| zIIP | The first value is the WLM system zIIP weight
recommendation. It is based on the amount of displaceable zIIP capacity
on this system, as compared to the other target systems. The second value is the first value modified by the expected zIIP usage proportion configured on the PORTLIST and WLM statement for this application. |
The first value is the WLM server-specific zIIP
recommendation. This is the amount of displaceable zIIP capacity,
based on the importance (as defined by the WLM policy) of the application's
workload, as compared to the other target systems. The second value is the first value modified by the proportion of zIIP capacity that is currently being consumed by the application's workload, as compared to the other processors (general CPU and zAAP). |
Restriction: This information is available to be displayed only
if no systems in the sysplex are prior to z/OS® V1R9. If any systems in the sysplex are
not at this release level, only CP weights are considered when determining
a composite weight recommendation.
