The WLM Service Definitions report provides a simple, yet
comprehensive, listing of the WLM Service Definitions in
effect for the time interval selected. This listing provides
an easy-to-follow method of understanding the definitions and
the effect the definitions have on the workload performance.
This information is helpful when trying to understand system
performance behavior and in interpreting information from
other WLM Goal Mode Service reports.
REPORT OPTIONS
Standard data selection options are supported as well as
SYSID selection and external data selection. Additionally,
input data may be further filtered by Sysplex or SVC
(Service) Class. These options are discussed in Section
2.2.7. The reports may be ordered either by WLM Service
Class (default), by WLM Importance, or by WLM Workload, as
specified by a panel option.
REPORT PAGE HEADER FIELDS
The following fields are displayed at the beginning of each
page of the report.
Sysplex: The name of the SYSPLEX that the service
definitions manage.
Service The name of WLM Service Definition currently
Definition: being reported on, from the CA MICS data
element WLMSDFNM.
Description: The description of the WLM Service Definition
(Svc. Def.) named above, from the CA MICS data element
WLMSDFDE.
Updated: The timestamp of the most recent update to the
(Svc. Def.) service definition, from CA MICS data element
WLMSDFTS.
By: The logon ID of the user who most recently
updated the service definition, from CA MICS
data element WLMSDUSR.
Service The name of the WLM Service Policy in effect
Policy: for this reporting interval, from CA MICS data
element WLMPOLCY. A service policy may be
thought of as a temporary, time-dependent
method of overriding goals for one or more
service class periods. This might be done for
different operational shifts or holidays, for
example, when processing requirements might
vary.
Description: The description of the WLM Service Definition
(Svc. Policy) named above, from the CA MICS data element
WLMPOLDE.
Updated: The timestamp of the most recent update to the
(Svc. Policy) service definition, from CA MICS data element
WLMPOLTS.
Ending Date: The date from the CA MICS Ending Timestamp of
the input data.
Reporting The interval of the report, from the CA MICS
Interval: common data element DURATION.
REPORT COLUMN HEADER FIELDS
Service The WLM Service Class name, from CA MICS data
Class: element WLMCLASS.
Class The description of the WLM Service Class named
Description: above, from the CA MICS data element WLMCLSDE.
Pd: The WLM Service Class period value, from
CA MICS data element WLMCLSPD.
Imp: The WLM Importance value, from CA MICS data
element WLMGOLRI.
Service The time interval, after which work will
Duration: transition to a later WLM Service Class period,
from CA MICS data element WLMPDDUR.
Workload: The name of the WLM Workload that the service
class belongs to, from CA MICS data element
WLMWRKLD.
Goal Type: The type of goal that the WLM Service Class
period is managed to, from CA MICS data element
WLMGOLTP. WLM Goal Types are either System
Specified, Execution Velocity, Response Time or
Discretionary, and are set by the user
according to the type of workload processed.
%: A ratio of the actual goal-defined service and
the target service specified, expressed as a
percentage and from CA MICS data element
WLMGOLPC.
Goal (secs): For response-time goals, the target response
time, expressed typically in seconds and from
CA MICS data element WLMGOLRT.
Resource The name of the WLM resource group in use by
Group: the service class, from CA MICS data element
WLMGROUP. Resource groups are an optional
method of limiting access to the processor.
This could be used to prevent CPU-bound work
from dominating a given service class, or to
otherwise restrict work, perhaps under some
sort of contractual arrangement. This option,
if specified, is in effect for the entire
Sysplex, not on a particular LPAR.
Protection Specifies whether work in a given service class
CPU Stor: is considered either CPU or Storage Critical.
YES indicates a critical specification; a blank
indicates no such specification.
