Announcement

WLMTK Version A.01.10.xx supports HP-UX 11i v1 (B.11.11), HP-UX 11i v2 (B.11.23), and HP-UX 11i v3 (B.11.31). It enhances functionality provided by HP-UX Workload Manager (WLM) and simplifies using WLM with other products.

WLM provides goal-based workload management. This management enables automatic resource allocation and application performance management through the use of prioritized service-level objectives (SLOs). It provides this functionality by automating features of HP Process Resource Manager (PRM), HP-UX Virtual Partitions, nPartitions, and processor sets.

WLMTK consists of several toolkits:

ODBTK

WLM Oracle Database Toolkit provides an easy mechanism for feeding Oracle database metrics into HP-UX WLM.

ODBTK offers the ability to:

Keep response times for your transactions below a given level by setting response-time SLOs
Increase an instance’s available CPU resources when a particular user connects to the instance
Increase an instance’s available CPU resources when more than n users are connected
Increase an instance’s available CPU resources when a particular job is active
Give an instance n percent of the CPU resources for each process in the instance (This feature is available only with HP-UX WLM Version A.01.02 and later.)
Give an instance n percent of the CPU resources for each user connection to the instance (This feature is available only with HP-UX WLM Version A.01.02 and later.)

ApacheTK

WLM Apache Toolkit facilitates the management and prioritization of Apache-based workloads.

The ApacheTK white paper illustrates how to:

Separate Apache from Oracle database instances
Separate Apache from batch work
Isolate a resource-intensive CGI workload
Isolate a resource-intensive servlet workload
Separate all Apache Tomcat workloads from other Apache workloads
Separate two departments’ applications using two Apache instances
Separate module-based workloads with two Apache instances
Manage Apache allocation by performance goal

WebLogicTK

WLM BEA WebLogic Server Toolkit provides a data collector called wlmwlsdc that tracks metrics indicating how busy WebLogic Server instances are.

WebLogicTK offers the ability to:

Manually provide a single instance an increasing amount of CPU resources in the form of a dynamic PSET (processor set) for benchmarking
Separate an instance from other workloads, as well as from other instances, while automatically maintaining performance using a dynamic PSET based on:
- Group usage of CPU resources
- Server instance queue metrics

For more information, see wlmwlsdc(1M) and the white paper Using HP-UX Workload Manager with BEA WebLogic Server, which offers various use cases. This paper is available at the following location:

SAPTK

In conjunction with HP Serviceguard Extension for SAP® (SGeSAP), the WLM SAP Toolkit enables WLM to integrate with SAP applications. The WLM SAP Toolkit provides a tool (wlmsapmap) that identifies SAP processes based on user-defined criteria and can be used in conjunction with WLM’s process map feature to assign the processes to specific workload groups managed by WLM. For more information, see wlmsapmap(1M).

In conjunction with WLM process maps, SAPTK offers the ability to:

Collect processes for an entire SAP instance and isolate them in a specified workload group
Collect SAP processes and separate them into different workload groups based on process types

SAPTK also offers several example configuration files.

SASTK

The WLM SAS Toolkit will be deprecated in a future release. A new, improved version will be made available and will include a white paper and example configuration files. The WLM SAS Toolkit provides enhancements to DMTK (also being deprecated) specifically for SAS users.

SASTK offers:

A SAS macro for instrumenting jobs to provide “percent complete” data to WLM for improved duration management
Example scripts showing how to manage the duration of SAS jobs

DMTK

The DMTK Toolkit has been deprecated.

SNMPTK

WLM SNMP Toolkit provides a data collector called snmpdc that fetches values from an SNMP agent for use as metrics in your WLM configuration. For more information, see snmpdc(1M).

SNMPTK offers the ability to retrieve metrics from sources such as PRM data for use in your WLM configuration.

The new features of these toolkits are described in “New in this version”.
