HP-UX Workload Manager Toolkits (WLMTK)

The Workload Manager Toolkits (WLMTK) product version A.01.05 enhances

functionality provided by WLM and simplifies the integration of various products with

WLM. These products include Apache, Oracle database instances, Pay Per Use, SAS,

SNMP, and WebLogic.

Summary of Change

• Utilities now use /opt/perl/bin/perl

The wlmoradc and smooth utilities, part of ODBTK, now use /opt/perl/bin/perl.

Similarly, the expsmooth utility, part of WebLogicTK, also uses

/opt/perl/bin/perl now. Formerly, all these utilities used

/usr/contrib/bin/perl.

• Installation now produces a warning if /opt/perl/bin/perl is not present on the

system

When installing WLM on a system where /opt/perl/bin/perl is not present:

— The following message appears in output and in the file

/var/adm/sw/swinstall.log:

* "hostname:/": 1 configure or unconfigure scripts had warnings.

— The following message appears in the file /var/adm/sw/swagent.log:

WARNING: Unable to locate /opt/perl/bin/perl. Install HP Perl 5.6.1

or later in order to use the provided Perl scripts.

• ApacheTK begins supporting Apache 2.x (For Apache 1.3.x support, use an earlier

ApacheTK release)

• 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) manpage.

• For optimal performance when managing Oracle instances, be sure your

wlm_interval (set in the WLM configuration) is at least 10 seconds.

• utilitydc has been modified as indicated below:

— It now supports the activation and deactivation of Temporary iCOD resources

based on your SLOs.

— It now allows you to specify a minimum number of processors to keep active on a

system. Even it utilitydc determines the system's SLOs can be met with fewer

processors, a certain number of processors can always be kept active. For more

information, see the -m option in the utilitydc (1M) manpage.
