About the perftune Script

Administrators typically run the Portal Server perftune script before performance tests or during system production.

The script does the following:

• Invokes the Access Manager amtune script and modifies the desktopconfig.properties file

• Tunes the Solaris^TM Operating System kernel and transmission control protocol (TCP) settings

• Prevents the script from tuning a system that lacks adequate memory

Configuration Changes

This section identifies configuration changes that the amtune script makes for the following Portal Server components:

• Web Server

• Application Server

• Directory Server

• Access Manager

• Portal Server Desktop
