Upgrade a SOA Agent to a 12.52 WSS Agent

This section contains the following topics:

How to Upgrade a SOA Agent

Upgrading a SOA Agent to a 12.52 WSS Agent involves several separate procedures. To upgrade your agent, Follow these steps::

Verify that you are in the proper step of the upgrade process for an agent upgrade. You upgrade agents to 12.52 from r12.1 SP3 at stage two of the CA SiteMinder® Web Services Security upgrade process, as shown in the following illustration:
Create backup copies of any customized agent-related files on your web server. Examples of files you could have customized after installing or configuring your agent include the following files:
- LocalConfig.conf
- WebAgent.conf
If you are upgrading an agent on a UNIX/Linux operating environment, clear the LD_PRELOAD variable.
Gather information for the following CA SiteMinder® programs.
- Agent installation wizard.
- Agent configuration wizard.
Run the installation wizard to upgrade your agent on Windows or UNIX.
If you are upgrading an agent on a UNIX/Linux operating environment, source the agent environment script on the upgraded agent).
Run the configuration wizard to configure the upgraded agent on Windows or UNIX.

Verify That the LD_PRELOAD Variable Does Not Conflict with Existing Agent

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

LD_PRELOAD=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 SiteMinder WSS 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:

Copy the SiteMinder WSS Agent installation executable file to a temporary directory on your web server.
Do one of the following steps:
- For wizard-based installations, right-click ca-sm-wss-<SVMVER>-cr-win32.exe, and then select Run as Administrator.
  
  cr
  
  Specifies the cumulative release number. The base 12.52 release does not include a cumulative release number.
- For console-based installations, open a command line window and run the executable as shown in the following example:
```
ca-sm-wss-<SVMVER>-cr-win32.exe -i console
```
Important! If you are running this wizard on Windows Server 2008, run the executable file with Administrator permissions, even if you are logged into the system as an Administrator. For more information, see the CA SiteMinder® Web Services Security Release Notes.
Use the information that you gathered previously to complete the installation.

Note: The software upgrade occurs in the installed location of the existing SOA Agent.

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

The installation program for the SiteMinder WSS 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.

Follow these steps:

Copy the SiteMinder WSS Agent installation executable file to a temporary directory on your web server.
Log in as a root user.
Do one of the following steps:
- For wizard-based installations, run ca-sm-wss-<SVMVER>-cr-unix_version.bin
  
  cr
  
  Specifies the cumulative release number. The base 12.52 release does not include a cumulative release number.
  
  unix_version
  
  Specifies the UNIX version: sol or linux...
- For console-based installations, open a command-line window and run the executable as shown in the following example:
```
ca-sm-wss-<SVMVER>-cr-unix_version.bin -i console
```
Use the information from your agent Installation worksheet to complete the installation program.

Note: The software upgrade occurs in the installed location of the existing SOA Agent.

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:

Operating System	Name of Library Path Variable
AIX	LIBPATH
Linux	LD_LIBRARY_PATH
Solaris	LD_LIBRARY_PATH

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

Run the Configuration Wizard on Your Upgraded SiteMinder WSS 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:

Open the following directory on your web server:
```
WSS_Home\install_config_info
```
WSS_Home

Specifies the path to where CA SiteMinder® Web Services Security is installed.

Default: C:\Program Files\CA\Web Services Security
Use one of the following configuration methods:
- For a GUI-based configuration, right-click ca-pep-config.exe, and then select Run as Administrator:
- For a console-based configuration, enter the following command from a Command Prompt window with Administrator privileges open to WSS_Home\install_config_info:
```
ca-pep-config.exe -i console
```
  Important! If you are running this wizard on Windows Server 2008, run the executable file with administrator permissions. Use these permissions even if you are logged in to the system as an administrator. For more information, see the release notes for your CA SiteMinder® component.
Use the information you gathered earlier to complete the wizard.
The agent runtime instance is created for your web servers.

Run the Configuration Wizard on Your Upgraded SiteMinder WSS 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.

Follow these steps:

Open a Console Window with root privileges on your web server:
Navigate to the following location:
```
WSS_Home/install_config_info
```
WSS_Home

Specifies the path to where CA SiteMinder® Web Services Security is installed.
Enter one of the following commands:
GUI Mode: ./ca-pep-config.bin

Console Mode: ./ca-pep-config.bin -i console

The Configuration Wizard starts.
Use one of the following configuration methods:
- For a GUI-based configuration, run ca-pep-config.bin.
- For a console-based configuration, open a Command prompt window with root privileges and enter the following command:
```
ca-pep-config.exe -i console
```
Use the information you gathered earlier to complete the wizard.
The agent runtime instance is created for your web servers.
