1 HP-UX WLM Toolkits (WLMTK) Release Notes This release notice contains the following information about HP-UX Workload Manager Toolkits Version A.01.07.
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 a particular job is active • Give an instance n perc
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 /opt/wlm/toolkits/weblogic/doc/weblogic_wlm_howto.html. The new features of these toolkits are described in the next section. What’s in this version WLMTK Version A.01.07.01 provides the toolkits ApacheTK, DMTK, ODBTK, PPUTK, SASTK, SNMPTK, and WebLogicTK. The new functionality of the individual toolkits is described below.
ODBTK: Problematic SQL statements Issue wlmoradc provides minimal checking of the SQL it passes to SQL*Plus. If SQL*Plus finds problems with the SQL statements, messages are sent to syslog or stderr. In some cases, SQL*Plus cannot execute the statements, resulting in a warning and a reported execution time (walltime) of 0 seconds. Wo karund To avoid such events, always verify your SQL by hand before finalizing your WLM and wlmoradc configuration files.
[Sun Dec 14 18:02:40 2003] [error] 14688: ModPerl::Registry: Can’t locate Apache.pm in @INC nl nl These errors indicate that the Apache environment has issues with the example mod_perl workload pig.pl. Workaround Use a different mod_perl workload that you know works with your Apache environment. Alternatively, focus on the .cgi and .php example workloads used in the same section of the white paper.
Wo karund This message typically occurs when your system has no more processors available for activation. (The message is not an indication that utilitydc failed to operate normally.) WebLogicTK: javax/security/auth/callback/CallbackHandler error Issue Monitoring a WebLogic instance with wlmwlsdc can produce a javax/security/auth/callback/CallbackHandler error. In particular, running the wlmwlsdc data collector with a single argument: % /opt/wlm/toolkits/weblogic/bin/wlmwlsdc \ /home/wladmin/wlm/myinstA.
To invoke wlmwlsdc with the setEnv.sh file inside a WLM configuration file, your coll_argv statement would be as follows: coll_argv = { nl wlmrcvdc /opt/wlm/toolkits/weblogic/bin/wlmwlsdc nl /home/wladmin/wlm/myinstA.props /opt/bea/user_projects/domains/mydomain/setEnv.sh nl } For more information on the possible settings and security considerations for this shell file, see the white paper Using HP-UX Workload Manager with BEA WebLogic Server, section “12.1.
Table 1 Component toolkits and their installation requirements (continued) Component toolkit Supported with ApacheTK The Using HP-UX Workload Manager with Apache white paper was written using the following packages: • HP-UX Workload Manager (WLM) Version A.02.02 (B8843CA) However, you can use other versions (starting at WLM Version A.01.01) in most circumstances to accomplish the management outlined in the paper. • HP-UX Apache-based Web Server B.1.0.09.01 based on Apache version 2.0.
NOTE: HP-UX WLM Version A.01.02 is the first version to offer the cpushares keyword. With ODBTK, this keyword allows you to give an instance n percent of the CPU per some metric, such as “user connection”. Compatibility with WLM’s vPar, nPar, and PSET management Do not use the PPUTK command utilitydc when using WLM’s vPar or nPar management. Also, do not use it when you have PSET-based workload groups.
3. If you are going to use ODBTK (wlmoradc, smooth) or WebLogicTK (expsmooth), or ApacheTK (wlm_watch.cgi): The wlmoradc, smooth, wlm_watch.cgi, and expsmooth utilities all require /opt/perl/bin/perl. Starting with WLM A.02.02, WLM offers a cntl_smooth configuration file keyword. It is recommended that you use the cntl_smooth WLM keyword instead of the smooth tool and the expsmooth tool. For information on cntl_smooth, see the wlmconf(4) man page.
