On HP-UX, you can control whether the gWLM CMS daemon (gwlmcmsd) and its agent daemons on the managed nodes (gwlmagent) start at boot by:

•Manually setting variables in the /etc/rc.config.d/gwlmCtl file. (The /sbin/init.d/ gwlmcmsd and /sbin/init.d/gwlmagt scripts use these variables.)

•Using the --enable_start_on_boot and --disable_start_on_boot options to gwlmcmsd and gwlmagent.

On Windows, to control whether the gWLM CMS daemon (gwlmcmsd) starts at boot: Right-click the My Computer icon, click Manage, double-click Services & Applications, double-click Services, right-click HP Global Workload Manager Central Management Server, select Properties, and change the Startup type to the desired setting.

NOTE: HP recommends starting these daemons at boot only when used in a secure operating environment.

Setting GWLM_CMS_START to 0 (zero) prevents automatic use at boot of HP Matrix OE visualization and HP Capacity Advisor.

The gwlmCtl file is shown below:

Automatic restart of gWLM’s managed nodes in SRDs (high availability)

Whenever a managed node boots, the node’s gWLM agent attempts to automatically rejoin the node in its SRD, providing high availability. The only configuration steps you need to perform for this behavior to happen are:

1.Ensure the /etc/rc.config.d/gwlmCtl file on each managed node has

GWLM_AGENT_START set to 1. You can run the following command on each system where gwlmagent is running to make this change for you:

#/opt/gwlm/bin/gwlmagent --enable_start_on_boot

In the same file, you also need GWLM_CMS_START=1 on the system where gwlmcmsd is running. However, when you ran vseinitconfig during installation, this change was automatically made.

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.
