If you are using Transact-SQL to create the maintenance plan, use the following SQL statements:

USE gwlm

GO

ALTER INDEX ALL ON gwlm_config_wkld REBUILD

GO

Setting gWLM properties

gWLM provides two properties files that allow you to control various gWLM behaviors. One file is for the CMS daemon or service, and the other is for use on all the managed nodes. Read the files for information on the behaviors they control.

CMS properties

The CMS properties are in /etc/opt/gwlm/conf/gwlmcms.properties on HP-UX and in C:\Program Files\HP\Virtual Server Environment\conf\gwlmcms.properties

on Windows. (The given Windows path is the default; however, a different path might have been selected at installation.)

NOTE: Some values are read by gWLM only when a daemon or service is started; while other values are read when an SRD is deployed. Refer to the file for information on when individual properties are read.

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

The gwlmcms.properties file is shown below.

#You must restart gwlmcmsd for changes made to this file

#Set FileHandler log level for the following log files:

#/var/opt/gwlm/gwlmcmsd.log.0

#/var/opt/gwlm/gwlmcommand.log.0

#/var/opt/gwlm/gwlm.log.0

#/var/opt/vse/logs/gwlminitconfig.log.0

#Valid levels, from most severe to least, are:

#SEVERE

#WARNING

#INFO

#CONFIG

#FINE

#FINER

#FINEST

#When you set the level, you will see messages only from that level and

#the levels that are more severe. So, the SEVERE level produces the fewest

#messages, while the FINEST level includes messages from all seven levels.

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.
