where hostname represents the hostname of the CMS.

3.From the System Insight Manager menu bar, select: Tools→HP Matrix OE visualization...

and then click the Shared Resource Domain tab.

4.Select the shared resource domain containing the workload for which you want to change the policy.

5.Select the workload for which you want to change the policy.

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

7.From the Policy dropdown in the table row for the workload, select the new policy to associate, or apply, to the workload.

8.Click OK.

Adding a new compartment or GiCAP group member to an SRD

If you:

•Have added an npar, a vpar, a VSP, or a virtual machine to your system and want to add it to an SRD,

•Have added a Global Instant Capacity (GiCAP) group member and want to add it to an SRD, or

•Want to create psets or fss groups in a host already in an SRD

You can use the gWLM wizard to accomplish those tasks. To start the wizard, select from the System Insight Manager menu bar:

Tools→HP Matrix OE visualization...

and then click the Shared Resource Domain tab. From the HP Matrix OE visualization menu bar, select:

Create→Shared Resource Domain

Step 1 in the wizard allows you to add nPars, vPars, VSPs, and GiCAP group members. Step 3 allows you to create psets or fss groups, as well as manage existing virtual machines.

NOTE: When you are managing nodes in a GiCAP group, if all partitions of a GiCAP group are not added to an SRD, a warning message is logged. To view the warning message in the GUI, on the CMS click Optimize→Global Workload Manager (gWLM)→Events and select the check box for Warning Message Logged. You can select the required severity level.

Stop managing a workload

When you stop managing a workload:

•gWLM stops managing resources for the workload

•The workload’s definition is removed from the SRD, although it remains available for placing in another SRD

NOTE: When gWLM stops managing npar-based or vpar-based workloads, it leaves the nPars or vPars with the number of cores they had in the last allocation interval. For this reason, in Step 3 below, you associate fixed policies with the workloads based on these types of compartments. You must stop a virtual machine before you stop managing it with gWLM. When gWLM stops managing a virtual machine, it sets the entitlement of the running virtual machine to its minimum. For psets and fss groups, gWLM removes the pset or fss group and moves the processes from that compartment to the default compartment.

To stop managing workloads in an SRD:

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.
