HP Systems Insight Manager 5.2 Installation and Configuration Guide for HP-UX

13 Configuration options
Several configurable parameters in HP SIM that are not available from the GUI. These parameters can only
be configured by editing a configuration file on the CMS.
NOTE: All HP SIM parameters have been set to predefined values that are appropriate for most situations.
These parameters should only be changed if you are experiencing issues with the default values.
There are two main default locations where HP-UX configuration files are stored. /etc/opt/mx/config
/opt/hpwebadmin/lib
These files follow the format of a Java properties file. Therefore, the keys in these files are case-sensitive. In
addition, the backslash (\) must be represented by a double-backslash (\\). For more information about the
Java property file format, refer to http://java.sun.com/.
This chapter provides information on the following configuration options:
• “CPU utilization during data collection”
• “GUI time-out policy”
• “HP SIM audit log configuration”
• “Lifetimes for entries on the Task Results Page”
CPU utilization during data collection
Overview
The data collection task runs many threads in parallel to overlap computing and database operations with
the wait for managed systems to respond. On slower systems, this could potentially saturate the CPU for
some time, depending on the processor speed of the CMS system and the number of systems being collected.
Therefore, HP SIM provides some strategies to lessen the CPU usage.
Implementation
To lessen the CPU usage during data collection on the CMS:
• Limit the number of systems that are being collected at one time. For example, create separate data
collection tasks for different groups of systems and schedule them to run at different times.
• Lower the DataCollectionThreadCount parameter in the globalsettings.props file. This
parameter defaults to 3. Lowering it to 2 or 1 reduces the CPU demand of data collection tasks, but it
increases the time required to complete the tasks.
GUI time-out policy
Overview
HP SIM provides two alternative time-out policies. The first time-out policy is for environments in which HP
SIM is used to monitor system status, which is called the monitor time-out policy, and it is similar to the policy
used by Insight Manager 7. The second time-out policy is more strict and will time-out inactive users. This is
called the active time-out policy and it is similar to the policy, used by Servicecontrol Manager.
Monitor time-out policy The monitor time-out policy keeps sessions alive, provided the user has a web
browser window open displaying the HP SIM GUI. Closing the browser or navigating to another web page
starts the timer for the time-out period. The default time-out period is 20 minutes. Users must use some other
means to protect an unattended session from illegal use, such as password-protected screen savers.
Active time-out policy The active time-out policy only keeps sessions alive if the user is actively using the
GUI, such as clicking on links and buttons. Display and refresh of the banner is not sufficient to keep the
session alive. The user is timed-out either by inactivity, closing the browser, or navigating to another site.
The default time-out period is 20 minutes.
