How to Prepare for a CA SiteMinder® Agent Upgrade

Upgrading a CA SiteMinder® agent involves several separate procedures. To prepare for an upgrade of your agent, follow these steps:

1. Use one of the following diagrams to verify that you are in the proper step of the CA SiteMinder® upgrade process for an agent upgrade:
   • Upgrade process from r6.x
   • Upgrade process from r12.0
2. Create backup copies of any customized CA SiteMinder® files on your web server. Examples of files you could have customized after installing or configuring your agent include the following examples:
   • LocalConfig.conf
   • WebAgent.conf
3. Gather information for the following CA SiteMinder® programs.
   • Agent installation wizard.
   • Agent configuration wizard.
4. If you are upgrading an agent on a UNIX/Linux operating environment, clear the LD_PRELOAD variable. Otherwise, continue with the next step.
5. Use one of the following procedures to upgrade your agent:
   • Run the installation wizard for Windows operating environments.
   • Run the installation wizard for UNIX/Linux operating environments.
6. If you are upgrading an agent on a UNIX/Linux operating environment, set the LD_LIBRARYPATH variable. Otherwise, continue with the next step.
7. Use one of the following procedures to configure the upgraded agent:
   • Configure your upgraded agent on Windows operating environments.
   • Configure your upgraded agent on UNIX/Linux operating environments.

Note: For more information about the CA SiteMinder® upgrade process, see the Upgrade Guide.

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.

Run the Installation Wizard to Upgrade your Agent on Windows

The installation program for the agent installs the agent on one computer at a time using the Windows operating environment. This installation program can be run in wizard or console modes. The wizard and console-based installation programs also create a .properties file for subsequent installations and configurations using the unattended or silent method with the same settings.

For example, suppose the Agents in your environment use the same web server version, installation directory, Agent Configuration Object and Policy Servers. Use the installation wizard or console-based installation program for your first installation. Afterwards, you could create your own script to run the installation program with the .properties file the wizard or console-based installation program created.

Follow these steps:

1. Copy the Web Agent installation executable file to a temporary directory on your web server.
2. Do one of the following steps:
   • For wizard-based installations, right-click the installation executable file, and then select Run as Administrator.
   • For console-based installations, open a command line window and run the executable as shown in the following example:

     executable_file_name.exe -i console
     

3. Use the information that you gathered previously to complete the installation.

Run the Installation Wizard to Upgrade your Agent on UNIX/Linux

The installation program for the CA SiteMinder® agent installs the agent on one computer at a time using the UNIX or Linux operating environments. This installation program can be run in wizard or console modes. The wizard and console-based installation program also creates a .properties file for subsequent installations and configurations using the unattended or silent method with the same settings.

For example, suppose the Agents in your environment use the same web server version, installation directory, Agent Configuration Object and Policy Servers. Use the installation wizard or console-based installation program for your first installation. Afterwards, you could create your own script to run the installation program with the .properties file the wizard or console-based installation program created.

Follow these steps:

1. Copy CA SiteMinder® agent installation executable file to a temporary directory on your web server.
2. Log in as a root user.
3. Do one of the following steps:
   • For wizard-based installations, run the installation executable file.
   • For console-based installations, open a command-line window and run the executable as shown in the following example:

     executable_file_name.exe -i console
     

4. Use the information from your agent Installation worksheet to complete the installation program.

Set the Library Path Variable Before Configuring your Upgraded Agent on UNIX/Linux

Set the library path variable on UNIX or Linux systems before running the agent configuration program.

The following table lists the library path variables for the various UNIX and Linux operating environments:

Set the value of the library path variable to the web_agent_home/bin directory.

web_agent_home

Indicates the directory where the CA SiteMinder® Agent is installed.

Default (UNIX/Linux installations): /opt/ca/webagent

Configure your Upgraded Agent on Windows

After gathering the information for your agent configuration, run the agent configuration program. This program creates an agent runtime instance for the web servers running on your computer.

This configuration program is wizard or console based, depending on the option you select. Running the configuration program in the wizard or console mode once creates a properties file. Use the properties file to run unattended configurations on other computers with same operating environment in the future.

Follow these steps:

1. Open the following directory on your web server:

   web_agent_home\install_config_info
   

   web_agent_home

   Indicates the directory where the CA SiteMinder® agent is installed on your web server.

   Default (Windows 32-bit installations only): C:\Program Files\CA\webagent

   Default (Windows 64-bit installations only): C:\Program Files\CA\webagent\win64

   Default (Windows 32-bit applications operating on 64-bit systems [Wow64]): C:\Program Files (x86)\webagent\win32

2. Use one of the following configuration methods:
   • For a GUI-based configuration, go to Step 3.
   • For a console-based configuration, go to Step 5.
3. Right-click the following executable, and then select Run as Administrator:

   ca-wa-config.exe
   

4. Go to Step 8.
5. Open a Command Prompt window with Administrator privileges.
6. Navigate to the executable file listed previously, and then run it with the following switch:

   -i console
   

7. Go to Step 8.
8. Follow the prompts shown in the configuration program. Provide the requested values from your agent configuration worksheet.

   The agent runtime instance is created for your web servers.

Configure your Upgraded Agent on UNIX/Linux

After gathering the information for your agent configuration, run the agent configuration program. This program creates an agent runtime instance for the web servers running on your computer.

This configuration program is wizard or console based, depending on the option you select. Running the configuration program in the wizard or console mode once creates a properties file. Use the properties file to run unattended configurations on other computers with same operating environment in the future.

Follow these steps:

1. Open the following directory on your web server:

   web_agent_home/install_config_info

   web_agent_home

   Indicates the directory where the CA SiteMinder® Agent is installed.
