Integrating with SAS software
WLM provides integration with SAS software through the WLM Toolkit
for Base SAS Software (SASTK). This toolkit, which is part of the freely
available WLM Toolkits, or WLMTK, product relies upon the WLM
Duration Management Toolkit, DMTK.
NOTE The HP-UX WLM Duration Management toolkit (DMTK), including its
wlmdurdc command, and the HP-UX WLM Toolkit for Base SAS
Software (SASTK), will be deprecated in a future release. However, a
new and improved SASTK will be made available and will include a
white paper and example configuration files. Support for the DMTK
wlmdurdc command will be removed in a future release. In the
meantime, for wlmdurdc documentation, see the wlmdurdc(1M). HP
recommends using usage-based controllers instead of DMTK.
WLM and DMTK help control CPU resources by granting a critical job
only the amount of CPU resources needed to complete within a certain
timeframe. Because the business-critical job is being duration managed,
the extra compute resource on the server can be made available to other
users or jobs without affecting the managed business-critical job. This
translates to more efficient use of existing compute resources. This
feature, known as duration management, is useful in Base SAS
environments and many other environments.
Furthermore, even without DMTK, WLM can grant computing resources
upon demand by providing an “express lane” to ensure that your most
important jobs are given top priority. Express lanes can be particularly
beneficial in a Base SAS environment where any user has the ability to
launch a job that can, regardless of its business priority, significantly
affect the performance of other jobs.
Why use SASTK?
Combining SASTK with DMTK, you can control your SAS jobs using:
• Job duration providing jobs just the right amount of CPU
resources—not too much or too little—to finish within user-specified
time ranges
