Results of Running the Configuration Wizard After an Upgrade

When you run the Web Agent Configuration Wizard after upgrading the Web Agent, the following occurs:

• SiteMinder saves a copy of the current Web Agent configuration file (WebAgent.conf).
• SiteMinder moves the IgnoreExt and BadURLCharacters lines into the new WebAgent.conf file as commented lines, so that you can easily add your custom elements.

Note: SiteMinder does not save a copy of the Trusted Host configuration file (SmHost.conf).

Ensure LD_PRELOAD Variable Does Not Conflict with Existing Agent

If you are upgrading or reinstalling a Web Agent on a Linux system, from the shell, set the LD_PRELOAD variable so that it points to a different location from any existing Web Agent installation directory. For example, if an existing LD_PRELOAD entry is set to:

LD_PRELOAD=web_agent_home/bin/libbtunicode.so

Before you reinstall or upgrade, set the variable to:

export LD_PRELOAD=

This entry sets the variable to a blank value.
