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
The new features of these toolkits are described in the next section. What’s in this version WLMTK Version A.01.08 provides the toolkits ApacheTK, DMTK, ODBTK, PPUTK, SASTK, SNMPTK, and WebLogicTK. The new functionality of the individual toolkits is described below. • Terminology change: The Instant Capacity on Demand (iCOD) product is now known as Instant Capacity, or iCAP.

Wo karund If the ERROR message and the DEBUG message disagree, ignore the DEBUG message. ApacheTK: Elapsed time reported may not be for a successful page fetch Issue If you use the ApacheTK tool time_url_fetch with a URL that Apache cannot serve (such as http://mytestmachine/misspelllllled_url.htm) the ab tool and time_url_fetch report the elapsed time for Apache to serve up a “Not found” msg. Neither tool considers this an error, although an individual trying to access this URL might.

} 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 “12.1.4 wlmwlsdc POSIX environment variable scripts”. The paper is available from the web site http://www.hp.com/go/wlm in the “information library” and is installed on your system at /opt/wlm/toolkits/weblogic/doc/weblogic_wlm_howto.html.
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 virtual partition, nPartition, and PSET management Do not use the PPUTK command utilitydc when using WLM’s virtual partition or nPartition 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.
