#TiCAP when the available balance goes below this threshold. The

#TiCAP, it must be available on the complex and enabled at the policy

#level or the SRD level.

com.hp.gwlm.node.ticap.minimumBalance = 30

Communications ports

gWLM uses the following ports for communications:

Managed nodes: 9617

CMS: 9618

If you need to change these ports, add the following lines:

com.hp.gwlm.cms.port = portX

com.hp.gwlm.node.port = portY

to both properties files:

•gwlmcms.properties

On HP-UX, this file is in /etc/opt/gwlm/conf/. On Windows, it is in C:\

Program Files\HP\Virtual Server Environment\conf\. (The given Windows path is the default; however, a different path might have been selected at installation.)

•/etc/opt/gwlm/conf/gwlmagent.properties

The portX and portY values cannot be the same value.

The com.hp.gwlm.cms.port property must have the same portX value in all the properties files—across all managed nodes and on the CMS. Similarly, the com.hp.gwlm.node.port property must have the same portY value in all the properties files—across all managed nodes and on the CMS.

You must restart gwlmcmsd and gwlmagent for the changes to take effect. If you are using gWLM through System Insight Manager, you must also restart System Insight Manager. (On HP-UX, restart Ststem Insight Manager daemons using /opt/mx/bin/mxstop and mxstart. On Windows, restart the HP Systems Insight Manager service.)

NOTE: Restarting gwlmcmsd temporarily disables HP Matrix OE visualization and HP Capacity Advisor.

Controlling gWLM’s startup behavior

The gWLM CMS daemon or service (gwlmcmsd) is set to start at boot by vseinitconfig. Generally, you should not change this setting as it disables all HP Matrix Operating Environment from starting at boot.

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.
