1.Ensure in System Insight Manager, the gWLM CMS daemon or service (gwlmcmsd), and all the gWLM agents (gwlmagent) are still running, as explained in the section “Setting up gWLM (initial setup steps)” (page 21).

2.Connect to System Insight Manager by pointing your web browser to: http://hostname:280

where hostname represents the hostname of the CMS.

3.Associate fixed policies with all workloads that you want to unmanage that are based on nPars or vPars.

For information on setting the associated policy, refer to “Changing which policy is associated with a workload” (page 23).

4.Wait an allocation interval for gWLM to set CPU resource allocations based on the fixed policies.

5.Click the Shared Resource Domain tab.

6.Select the workload you want to stop managing in the workload table.

7.From the HP Matrix OE visualization menu bar, select: Policy→Remove Associated gWLM Policy...

8.Associate policies.

Evaluate and change, if needed, the remaining workloads and their associated policies to ensure they are appropriate, given that a workload has been removed.

9.Click OK.

Stop managing an SRD

To stop gWLM from managing an SRD and its workloads, returning resource allocation to HP-UX:

NOTE: In System Insight Manager, you must be logged in as root or have authorizations for “All Tools” or “Matrix OE All tools.”

1.Ensure in System Insight Manager, the gWLM CMS daemon or service (gwlmcmsd), and all the gWLM agents (gwlmagent) are still running, as explained in the section “Setting up gWLM (initial setup steps)” (page 21).

2.Connect to System Insight Manager by pointing your web browser to: http://hostname:280

where hostname represents the hostname of the CMS.

3.Associate fixed policies with all nPars or vPars that were in the SRD.

When gWLM stops managing an SRD, it leaves compartments based on nPars or vPars as they were in the last allocation interval. Associating fixed policies allows you to set the sizes exactly to what you want. (For virtual machines, gWLM sets the entitlements of the running virtual machines to their minimums. psets and fss groups are removed in this situation, with their processes going to the default pset or default fss group.)

For information on setting the associated policy, refer to “Changing which policy is associated with a workload” (page 23)

4.Click the Shared Resource Domain tab.

5.Select the SRD that you want to stop managing (undeploy).

6.From the HP Matrix OE visualization menu bar, select: Modify→Shared Resource Domain

7.Change to the Undeployed state.

8.Click OK.

UX 11i Workload Management (gWLM/WLM) Software specifications

HP-UX 11i Workload Management (gWLM/WLM) software is an integral component of HP's premier UNIX operating system, designed to enhance system performance and resource management across diverse workloads. This advanced tool allows system administrators to monitor, control, and allocate resources effectively to achieve optimal performance, reliability, and service levels in enterprise environments.

One of the main features of gWLM/WLM is its ability to classify workloads and manage them according to specific policies set by the administrator. By using service level objectives (SLOs), administrators can define the performance criteria for various applications and workloads. gWLM continuously tracks these workloads, ensuring that they adhere to the defined SLOs, thus maintaining a high level of application performance.

The software employs resource pools, which segment resources such as CPU, memory, and I/O bandwidth among different workloads based on predefined priorities. This capability ensures that critical applications receive the resources they require, even during peak usage periods, thereby preventing resource starvation that could lead to system slowdowns or crashes.

Another significant characteristic of gWLM/WLM is its real-time monitoring and reporting capabilities. The software provides detailed insights into resource utilization, workload performance, and system health. Administrators can access this information through a user-friendly interface, allowing for informed decision-making and proactive management.

Integration with HP Serviceguard adds another layer of functionality, enabling high availability for critical applications. gWLM can orchestrate workload migration to ensure that service levels are maintained, even in the event of hardware failures or resource contention.

The technology behind gWLM/WLM is built on advanced algorithms that leverage historical data and predictive modeling to optimize resource allocation dynamically. This means that as workloads change, the system can automatically adjust resource distribution to meet performance targets without the need for constant manual intervention.

gWLM also supports integration with various enterprise management tools, enabling administrators to implement comprehensive monitoring and management strategies across the IT infrastructure. The scalability of gWLM allows organizations of all sizes to benefit from its robust workload management features, ensuring that they can adapt to changing demands in their operational environments.

In summary, HP-UX 11i Workload Management software offers a sophisticated solution for optimizing resource utilization, managing workloads effectively, and maintaining high performance in complex enterprise environments. Its comprehensive features and technologies make it an essential tool for any organization seeking to enhance their IT operations.
