HP-UX WLM Toolkits (WLMTK) Release Notes 1 HP-UX WLM Toolkits (WLMTK) Release Notes This release notice contains the following information about HP-UX Workload Manager Toolkits Version A.01.
HP-UX WLM Toolkits (WLMTK) Release Notes Announcement Announcement WLMTK Version A.01.06 supports HP-UX 11.0, HP-UX 11i V1.0 (B.11.11), and HP-UX 11i V2.0 (B.11.23). 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).
HP-UX WLM Toolkits (WLMTK) Release Notes Announcement ODBTK WLM Oracle Database Toolkit provides an easy mechanism for feeding Oracle database metrics into HP-UX WLM ODBTK offers the ability to: PPUTK • Keep response times for your transactions below a given level by setting response-time SLOs • Increase an instance’s available CPU when a particular user connects to the instance • Increase an instance’s available CPU when more than n users are connected • Increase an instance’s available CPU when
HP-UX WLM Toolkits (WLMTK) Release Notes Announcement SASTK WLM SAS Toolkit provides enhancements to DMTK specifically for SAS users SASTK offers: SNMPTK • 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 WLM SNMP Toolkit provides a data collector called snmpdc that fetches values from an SNMP agent for use as metrics in your WLM configuration.
HP-UX WLM Toolkits (WLMTK) Release Notes What’s in this version What’s in this version WLMTK Version A.01.06 provides the toolkits ApacheTK, DMTK, ODBTK, PPUTK, SASTK, SNMPTK, and WebLogicTK. The new functionality of the individual toolkits is described below. • PPUTK’s utilitydc has been modified as indicated below: — -f This option was previously for specifying the number of consecutive WLM intervals over which an EMS resource must be the same value before utilitydc activated a processor.
HP-UX WLM Toolkits (WLMTK) Release Notes Known problems and workarounds Known problems and workarounds This section discusses problems and workarounds. ODBTK: No control of instance on start-up Issue Assume a database instance is managed by HP-UX WLM. If WLM starts before that instance, it sets the CPU allocation for the instance’s workload group based on the mincpu and maxcpu values in the WLM configuration file.
HP-UX WLM Toolkits (WLMTK) Release Notes Known problems and workarounds ODBTK: Debug clean_exit code is not useful Issue If wlmoradc detects a command-line error and debugging is enabled, the code reported by clean_exit may not be useful.
HP-UX WLM Toolkits (WLMTK) Release Notes Known problems and workarounds ApacheTK: Errors with the pig.pl workload in the white paper Issue In the “Using HP-UX Workload Manager with Apache” white paper, in section 13.4.0.7, the step using pig.pl to generate load, namely: Then visit (several times, if necessary) http://mymachine:8090/cgi-bin/pig.pl while watching the output of wlminfo group. may produce error messages and not generate the desired load.
HP-UX WLM Toolkits (WLMTK) Release Notes Known problems and workarounds PPUTK: Capping issue may affect PPUTK Issue WLM maintains CPU allocations for workloads by capping their CPU access. Unfortunately, an algorithm in the CPU scheduler that WLM uses does not always preserve capping when one or more CPUs are deactivated on a Pay Per Use system or an iCOD system. Workaround Configure WLM as desired and then determine whether the capping issue is present on your system.
HP-UX WLM Toolkits (WLMTK) Release Notes Known problems and workarounds PPUTK: utilitydc does not honor passive mode Issue utilitydc continues to activate/deactivate CPUs even when WLM is started in passive mode (wlmd -p). Workaround The workaround is to use the none argument to the utilitydc -i option in the coll_argv statement that calls utilitydc in your WLM configuration. The none argument prevents utilitydc from changing the active CPU count.
HP-UX WLM Toolkits (WLMTK) Release Notes Known problems and workarounds Workaround Provide a setting for both JAVA_HOME and WL_HOME when using WLS 8.1. There are two ways for settings these variables, as explained below. • Use a custom shell file You can provide custom environment variables in a new file specified when you invoke wlmwlsdc: % /opt/wlm/toolkits/weblogic/bin/wlmwlsdc \ /home/wladmin/wlm/myinstA.props \ my_custom_env_settings.sh The file my_custom_env_settings.

HP-UX WLM Toolkits (WLMTK) Release Notes Software availability in native languages PPUTK fix: utilitydc may activate CPUs when not useful In previous releases, utilitydc could activate a CPU to help meet a failing SLO that has already received its maximum CPU allocation. The failing SLO would not be able to take advantage of the additional CPU resources. Release A.01.06 fixes this issue. Software availability in native languages The man pages and user’s guide are available only in English.
