WLM Status tab

You can use the WLM Status tab in the Workload Management task in IBM® z/OS® Management Facility (z/OSMF) to view details about the active service policy and the installed service definition. You can also view details about each system in the sysplex such as the service policy that is in effect and the z/OS Workload Manager (WLM) status.

The information that is displayed in the WLM Status tab is retrieved from the WLM component running on the z/OSMF host system. The information is displayed in the following sections:

If you enabled Automatic refresh, the information refreshes automatically every 30 seconds. Otherwise, click the Refresh button to obtain the latest information.

Active Service Policy

This section provides information about the service policy that is active in the sysplex. Table 1 lists and describes the fields that are displayed in this section.

The link View performance of active policy enables you to view the performance of the active service policy. If the link is not displayed a provider of appropriate performance data is not available.

If your installation is using only z/OSMF to manage WLM service definitions, the service policy information should be the same as the policy information that is stored in the WLM couple data set. The only exception is when a service policy is currently being activated. In this case, this section displays details about the previous active service policy. After the current activation completes, the information is updated.

If your installation is also using the WLM Administrative Application to manage service definitions, inconsistencies could also occur for the following reasons:
  • The service policy was activated from a system other than the z/OSMF host system and the host system has not activated the policy yet.
  • The service policy that was activated has a functionality level that is higher than the functionality level of WLM on the host system; therefore, the host system cannot activate the service policy.
To minimize the possibility of inconsistencies, it is recommended that your installation use only one tool to manage your WLM service definitions.
Table 1. Fields in the Active Service Policy section
Field Description
Name Name of the active service policy.
Description Description of the active service policy.
Activated Date and time the service policy was activated.
Activated by User ID of the person who activated the service policy and the name of the system from which it was activated.
Related service definition Name of the service definition that contains the active service policy.
Functionality level Functionality level of the active service policy.
Installed Date and time the service definition was installed.
Installed by User ID of the person who installed the service definition and the name of the system from which it was installed.

Systems

The Systems table lists the status of all of the systems in the sysplex. For a description of the columns in the Systems table, see Table 2. For a description of the actions listed in the Actions menu, see Table 3.

If you removed a system from the sysplex, it might still be listed because WLM retains knowledge of the system for a certain amount of time in case your installation decides to reactivate the system. If the system is not activated within several days, the system is automatically removed from the list of systems.

The link View performance of systems enables you to view the performance of the systems in the sysplex. If the link is not displayed a provider of appropriate performance data is not available.

Table 2. Columns in the Systems table
Column Description
Name Name of the system.
Used Service Policy Name of the service policy that WLM is using to manage the workload on the system.
Activated Date and time the service policy was activated.
WLM Status Status of WLM on the system. WLM can have one of the following status:
  • Initializing. There is no workload management function available because WLM is initializing.
  • Active. The system is processing towards the active service policy.
  • Active, Not Running with Active Policy. WLM is active, but the active service policy is not available for one of the following reasons:
    • There is no WLM couple data set.
    • The system is not connected to the WLM couple data set.
    • The system is connected to the WLM couple data set but a service policy has not been activated.
    • A service policy is currently activating, but the system has not activated it yet.
    • The active service policy failed to activate on the system.
    • The service definition has over 100 service classes defined.
  • Quiesce In Progress. WLM is in the process of an orderly shutdown.
  • Cleanup Initiated by System system-name. WLM is inactive. Termination was not orderly and another system running WLM is performing recovery actions on behalf of this system, where system-name is the name of the system performing the recovery.
  • WLM Inactive, Cleanup Complete. WLM is inactive. It either terminated through an orderly shutdown or cross-system recovery actions have been completed.
  • System Inactive, Cleanup Pending. The system is not currently part of the sysplex. Cross-system recovery is scheduled to be performed on the system.
  • System Inactive, Cleanup Complete. The system is not currently part of the sysplex. However, before the system became inactive, cross-system recovery actions were completed.
  • Unknown. A system running WLM has detected that another system running WLM contains unreliable information. When this happens the system with the unreliable information is isolated and its WLM state is set to unknown. Error processing is started to determine the true WLM state for the system.
  • Not Available. The system might be in the process of coming up.
GPMP Status Status of the guest platform management provider (GPMP), which provides policy information to WLM so that WLM understands the platform wide performance goals of the workloads in which z/OS is participating.
Note: Beginning with z/OS V2R3, the GPMP is no longer available. If activation is enabled (YES is selected), WLM starts the GPMP only on systems that are z/OS V2R2 and below.

The guest platform management provider can have one of the following status:

  • Unknown. The status of the GPMP could not be retrieved.
  • Inactive. The GPMP was not started.
  • Unavailable. A platform performance management function is not available.
  • Started. The GPMP has been started, but has not connected to WLM.
  • Active. The GPMP is active and is connected to WLM, but has not established a connection to the IBM z Unified Resource Manager.
  • Failed. WLM attempted to start the GPMP; however, the agent did not connect to the IBM z Unified Resource Manager within the timeframe allotted. This state also occurs when WLM is unable to stop the GPMP.
  • Severe Failed. WLM attempted to start the GPMP. The request failed twice within 10 minutes, or the GPMP connection unexpectedly terminated twice within 10 minutes.
  • Connected. The GPMP is active and is connected to WLM and the IBM z Unified Resource Manager.
  • Stopped. The GPMP was manually stopped using either the MODIFY WLM,GPMP,STOP command or the MODIFY WLM,AM=DISABLE command. If the Application Response Measurement (ARM) component of WLM is disabled, you must enable it before you can restart GPMP. To enable ARM, issue the MODIFY WLM,AM=ENABLE command. Then, to restart GPMP, issue the MODIFY WLM,GPMP,START command.
  • Disabled. The ARM component of WLM is disabled.
  • Early IPL. Unix System Services or TCP/IP is not running.
  • Shutdownx. GPMP termination is currently in progress, where x is a number.
WLM Version Level Version of WLM that is running on the system. The WLM version level is displayed only for the z/OSMF host system.
CDS Format Level Format of the WLM couple data set (CDS) created via the XCF IXCL1DSU utility. If the WLM couple data set format level can be determined, then one of the following valid formats is shown:
  • FORMAT 1. Original format, as built in MVS/SP™ Release 5.1. This is the format level for MVS/SP Release 5.1 and 5.2.
  • FORMAT 2. Format updated in OS/390® Release 3, with the addition of application environments. This is the format level for OS/390 Release 3 only.
  • FORMAT 3. Format updated in OS/390 Release 4, with the addition of scheduling environments. This is the format level for OS/390 Release 4 and later.

The couple data set format level is displayed only for the z/OSMF host system.
Connected CF Structures Names of the coupling facility (CF) structures to which the z/OSMF host system is connected. Only the names of the coupling facility structures that are defined for multisystem enclaves and for logical partition (LPAR) clustering are shown, if applicable.
