Workaround

Use the --forceoption with gwlm deploy or gwlm undeploy to synchronize the agent and the CMS.

For example, run the following command to force both the agent and the CMS to consider the SRD as deployed, substituting the name of your SRD for SRD

# gwlm deploy --srd=SRD--force

For more information about the gwlm command, see gwlm(1M). The agents should be restarted to clear their configuration. The following steps should be performed on all agents:

#gwlmagent --stop

#rm /etc/opt/gwlm/deployed.config

#rm /var/opt/gwlm/RPmap (If it exists.)

#gwlmagent

Missing historical data (gWLM CMS daemon/service restarted)

You might have blank sections of a historic report for a workload, or you might see the following error message when displaying historic data for a workload:

There is no gWLM historical data for the workload MyWorkload.wkld. The workload has never been managed by gWLM, or the historical data has been removed.

Because of caching gWLM historic data in System Insight Manager, if the gWLM CMS daemon/service is restarted after initially viewing historic data, the interface incorrectly reports that there is no data available to view or fails to load portions of the data.

Workaround

Perform the following steps:.

1.Log out of System Insight Manager

2.Log in to System Insight Manager (again)

3.Generate the historic report (again)

Missing workload application criteria after gWLM and HPSIM service restart

If workloads are defined with application criteria, the criteria definition goes missing after gWLM and HPSIM restart.

Workaround

To restore the workload's application criteria definition:

1.Click Workload under Workloads tab.

2.Select by application option.

3.Select the application that is defined with the workload.

4.Click Add to definition.

5.Click OK.

After you click OK, the following error occurs:

The workload named <workload_name> already exists in the Application Discovery server.

6.Click Cancel and ignore the error message.

Negative current size for NONVM

If the CPUs on a VM Host are oversubscribed when you deploy an SRD on that host, gWLM shows current size for NONVM as a negative value.

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.
