Installing Agent for BEA WebLogic Server/Portal 9.2 in a Clustered Environment

If you are installing Agent for BEA WebLogic Server/Portal 9.2 in a clustered environment, you must perform many of the steps explained in this chapter. However, see Chapter 5, Installing and Configuring Policy Agent 2.2 for BEA WebLogic Server/Portal 9.2: Cluster. The installation and configuration of a clustered deployment is presented in that chapter combining specific tasks with generalized tasks. For the generalized tasks, you are directed to various locations in this guide to perform the more detailed steps required.

Installing Agent for BEA WebLogic Server/Portal 9.2 in a Stand-Alone Environment

Before describing any tasks, this chapter provides you with installation-related information specific to BEA WebLogic Server/Portal 9.2. The subsequent sections lead you through the pre—installation and installation steps and describe how to view the installation log files. First, perform the pre-installation (preparation) steps. Then, perform the installation itself. The installation process has two phases. The first phase of the installation includes launching the installation program, which requires a directory to already have been selected for the agent files. The second phase of the installation involves interacting with the installation program. During this phase, the program prompts you step by step to enter information. Accompanying the prompts, are explanations of the type of information you need to enter. After you complete the installation, you can look at the installation log files.

Follow the specific steps outlined in the following section before you install the agent to reduce the chance of complications occurring during and after the installation.

ProcedureTo Prepare to Install Agent for BEA WebLogic Server/Portal 9.2

Perform the following pre-installation tasks:

  1. Ensure that the Policy Agent 2.2 for BEA WebLogic Server/Portal 9.2 is supported on the desired platform as listed in Supported Platforms and Compatibility of Agent for BEA WebLogic Server/Portal 9.2.

  2. Install BEA WebLogic Server/Portal 9.2 if not already installed.

    For more information about BEA WebLogic Server/Portal 9.2, see the product documentation available at the following web site: http://www.bea.com/.

  3. Create a server or portal domain

    Using the configuration or domain wizard appropriate for your server version and operating system, create a new stand-alone server domain. Typically, the configuration wizard launch script or program is located in the respective directory as follows:

    UNIX—based systems (including Linux systems)

    DeployContainer-base/weblogic92/common/bin/config.sh

    Windows systems

    DeployContainer-base\weblogic92\common\bin\config.cmd

    where DeployContainer-base represents the directory in which BEA WebLogic Server/Portal 9.2 was installed.

  4. Shut down the BEA WebLogic Server/Portal 9.2 instance that will be protected by the agent.

  5. Create a valid agent profile in Access Manager Console if one has not already been created.

    For information on how to create an agent profile, see Creating a J2EE Agent Profile.

    To avoid a misconfiguration of the agent, ensure that you know the exact ID and password used to create the agent profile. You must enter the agent profile password correctly in the next step and you must enter the agent profile ID correctly when installing the agent.

  6. Create a text file and add the agent profile password to that file.

    Ensure that this file is located in a secure directory of your choice. You will refer to this file during the agent installation process.

    With the agent profile password in this file, stored in a secure location, you do not need to enter sensitive information in the command line. A valid password file can have only one line that contains the agent profile password.

    You must decide what to do with this password file after the installation process is complete. You might choose to remove the file or provide restricted permissions to it. However, certain deployment-related tasks, such as installing multiple instances, require a password file. If you do remove the password file, create a new one if a future situation requires it.

  7. Ensure that the ownership and group settings for the files in the Policy Agent base directory are correct.

    Note –

    The Policy Agent base directory is explained in more detail in J2EE Agent Directory Structure in Policy Agent 2.2 and Example 3–5. In summary, for this agent, Agent for BEA WebLogic Server/Portal 9.2, the Policy Agent base directory is named am_wl92_agent.

    Often, such installations are performed by a user with root permissions. In these cases, the potential problems discussed subsequently in this step would not apply.

    Therefore, if necessary, change the ownership of all the files in the Policy Agent base directory to the BEA WebLogic Server/Portal 9.2 installation user and change the group associated with these files to the same group associated with the BEA WebLogic Server/Portal 9.2 installation user.

    Caution – Caution –

    For the agent installation to be successful, the BEA WebLogic Server/Portal 9.2 installation user must have write permissions to the files in the Policy Agent base directory. Furthermore, to help prevent permission problems, the ownership of all the files in the Policy Agent base directory should be changed to the BEA WebLogic Server/Portal 9.2 installation user. Otherwise, permission-related issues might occur, which can be as serious as BEA WebLogic Server/Portal 9.2 not starting.

Launching the Installation Program of Agent for BEA WebLogic Server/Portal 9.2

Once you have performed all the pre-installation steps, you can launch the installation program as described in the following subsection.

ProcedureTo Launch the Installation Program of Agent for BEA WebLogic Server/Portal 9.2

To launch the installation program, perform the following steps:

  1. Change to the following directory:


    PolicyAgent-base/bin

    This directory contains the agentadmin program, which is used for installing a J2EE agent and for performing other tasks. For more information on the agentadmin program, see Role of the agentadmin Program in a J2EE Agent for Policy Agent 2.2.

  2. Ensure that you are the BEA WebLogic Server/Portal 9.2 installation user.

  3. Issue the following command:


    ./agentadmin --install

  4. (Conditional) If you receive license agreement information, accept or reject the agreement prompts. If you reject any portion of the agreement, the program will end.

    The license agreement is displayed only during the first run of the agentadmin program.

Using the Installation Program of Agent for BEA WebLogic Server/Portal 9.2

After you issue the agentadmin command and accept the license agreement (if necessary), the installation program appears, prompting you for information.

The steps in the installation program are displayed in this section in an example interaction. Your answers to prompts can differ slightly or greatly from this example depending upon your specific deployment. In the example, most of the defaults have been accepted. This example is provided for your reference and does not necessarily indicate the precise information you should enter.

The following bulleted list provides key points about the installation program.

About Installation Prompts in Agent for BEA WebLogic Server/Portal 9.2

The following list provides information about specific prompts in the installation. Often the prompt is self explanatory. However, at other times you might find the extra information presented here to be very helpful. This extra information is often not obvious. Study this section carefully before issuing the agentadmin --install command.

The Deployment URI for the Agent Application

The deployment URI for the agent application is required for the agent to perform necessary housekeeping tasks such as registering policy and session notifications, legacy browser support, and CDSSO support. Accept /agentapp as the default value for this interaction. Once the installation is completed, browse the directory PolicyAgent-base/etc. Use the agentapp.war file to deploy the agent application in the application container. Please note that the deployment URI for agent application during install time should match the deployment URI for the same application when deployed in the J2EE container.

The Encryption Key

This key is used to encrypt sensitive information such the passwords. The key should be at least 12 characters long. A key is generated randomly and provided as the default. You can accept the random key generated by the installer or create your own using the .agentadmin --getEncryptKey command.

For information about creating a new encryption key, see agentadmin --getEncryptKey.

The Agent Profile Name

An agent profile should have been created as a pre-installation step. The creation of the agent profile is mentioned in that section. For the pre-installation steps, see Preparing to Install Agent for BEA WebLogic Server/Portal 9.2. For the actual information on creating an agent profile, see Creating a J2EE Agent Profile.

In summary, the J2EE agent communicates with Access Manager with a specific ID and password created through an agent profile using Access Manager Console. For J2EE agents, the creation of an agent profile is mandatory. Access Manager uses the agent profile to authenticate an agent. This is part of the security infrastructure.

The J2EE Password File

The J2EE password file should have been created as a pre-installation step. For the pre-installation steps, see Preparing to Install Agent for BEA WebLogic Server/Portal 9.2.

When the installation program prompts you for the password for the agent, enter the fully qualified path to this password file.

After you have completed all the steps, a summary of your responses appears followed by options that allow you to navigate through those responses to accept or reject them.

When the summary appears, note the agent instance name, such as agent-001. You might be prompted for this name during the configuration process.

About the options, the default option is 1, Continue with Installation.

You can edit your responses as necessary, return to the options list, and choose option 1 to finally process your responses.

Example of Installation Program Interaction in Agent for BEA WebLogic Server/Portal 9.2

This section includes an example installation interaction of Policy Agent 2.2 installed on a BEA WebLogic Server 9.2 instance (not on a BEA WebLogic Portal 9.2 instance). For an example interaction of Policy Agent 2.2 installed on a BEA WebLogic Portal 9.2 instance, see Appendix D, Installation and Configuration Specific to BEA WebLogic Portal 9.2. That appendix leads you through both the installation and configuration of the agent on BEA WebLogic Portal 9.2. By no means does either installation example represent a real deployment scenario.

The section following this example, Implications of Specific Deployment Scenarios in Agent for BEA WebLogic Server/Portal 9.2, explains specific deployment scenarios, such as installing the agent on multiple deployment container instances on the same domain. If any of these deployment scenarios apply to your deployment, you might need to respond to prompts in a specified manner during the installation as explained in that section. Review the explanations in that section before proceeding with the installation. Those explanations are divided into subsections as follows:

Implications of Specific Deployment Scenarios in Agent for BEA WebLogic Server/Portal 9.2

The following subsections apply to both BEA WebLogic Server 9.2 and BEA WebLogic Portal 9.2.

The subsections that follow refer to specific deployment scenarios involving Policy Agent 2.2 for BEA WebLogic Server/Portal 9.2. These scenarios are likely to affect how you respond to prompts during the installation process. You might also need to perform additional configurations.

Installing a J2EE Agent on Multiple BEA WebLogic Server/Portal 9.2 Instances on the Same Domain

Once a J2EE agent is installed for a particular domain configuration directory, you can install the agent on more than one BEA WebLogic Server/Portal 9.2 instance associated with the same domain by running the agentadmin --install command. Once prompted to enter the appropriate server instance name, enter the domain configuration directory and unique instance name that will enable the agent to distinguish the first instance from consecutive instances.

Installing a J2EE Agent for a BEA WebLogic Server/Portal 9.2 Instance on a Different Server Domain

Caution – Caution –

Once a J2EE agent is installed for a specific domain, the J2EE agent binaries cannot be used on that same host for a different BEA WebLogic Server/Portal 9.2 domain. If you attempt to use previously installed J2EE agent binaries on the same host, but on a different domain, the installation fails.

J2EE agents associate a specific set of agent binaries with a particular domain for BEA WebLogic Server/Portal 9.2. If you want to install a J2EE agent on a different domain, unpack a new set of bits and copy them to a separate location before running the agentadmin --install command for the second domain.

Installing Agent for BEA WebLogic Server/Portal 9.2 on the Access Manager Host

Note –

The prompt illustrated in this section is presented by the installer of Agent for BEA WebLogic Server/Portal 9.2. However, at the time of the release of this agent, installing Access Manager on BEA WebLogic Server/Portal 9.2 is not supported. Until that support is in place, ensure the following apply:

Once this collocation scenario is supported, if Agent for BEA WebLogic Server/Portal 9.2 and Access Manager are installed on the same container, enter true for the following prompt:


Enter true if the Agent is being installed on the same instance of Application
Server on which Access Manager is deployed. Enter false if that is not the
case.
[ ? : Help, < : Back, ! : Exit ]
Are the Agent and Access Manager installed on the same instance of
Application Server ? [false]: true

Summary of a J2EE Agent Installation in Policy Agent 2.2

The summary illustrated in this section is more specific to BEA Weblogic 9.2 Server. However, the information is relatively generic and applies, more or less, to all J2EE agents in thePolicy Agent 2.2 software set, including BEA Weblogic 9.2 Portal. For an agent installation summary more specific to BEA Weblogic 9.2 Portal, see the summary included with the BEA WebLogic Portal 9.2 installation example in Installing Policy Agent 2.2 on BEA WebLogic Portal 9.2.

At the end of the installation process, the installation program prints the agent installation summary, which indicates the status of the installation along with the installed J2EE agent information. The information that the program displays can be very useful. For example, the program displays the agent instance name, which is needed when configuring a remote instance. The program also displays the location of specific files, which can be of great importance. In fact, you might want to view the installation log file once the installation is complete, before performing the post-installation steps as described in Chapter 4, Post-Installation Tasks of Policy Agent 2.2 for BEA WebLogic Server/Portal 9.2.

The location of directories displayed by the installer are specific. However, throughout this guide and specifically in the two summaries of the agent Installation, PolicyAgent-base is used to describe the directory where the distribution files are stored for a specific J2EE agent.

The following example serves as a quick description of the location of the J2EE agent base directory (PolicyAgent-base) of Policy Agent 2.2 for BEA WebLogic Server/Portal 9.2.

Example 3–5 Policy Agent Base Directory of Agent for BEA WebLogic Server/Portal 9.2

The following directory represents PolicyAgent-base of Agent for BEA WebLogic Server/Portal 9.2:


Agent-HomeDirectory/j2ee_agents/am_wl92_agent

where Agent-HomeDirectory is the directory you choose in which to unpack the J2EE agent binaries.

Information regarding the location of the J2EE agent base directory is explained in detail in Location of the J2EE Agent Base Directory in Policy Agent 2.2.

The following type of information is printed by the installer:


SUMMARY OF AGENT INSTALLATION
-----------------------------
Agent instance name: agent_001
Agent Configuration file location:
PolicyAgent-base/agent_001/config/AMAgent.properties
Agent Audit directory location:
PolicyAgent-base/agent_001/logs/audit
Agent Debug directory location:
PolicyAgent-base/agent_001/logs/debug

Install log file location:
PolicyAgent-base/logs/audit/install.log

Thank you for using Access Manager Policy Agent

Once the agent is installed, the directories shown in the preceding example are created in the agent_00x directory, which for this example is specifically agent_001. Those directories and files are briefly described in the following paragraphs.

PolicyAgent-base/agent_001/config/AMAgent.properties

Location of the J2EE agent AMAgent.properties configuration file for the agent instance. Every instance of a J2EE agent has a unique copy of this file. You can configure this file to meet your site's requirements. For more information, see the following sections:

PolicyAgent-base/agent_001/logs/audit

Location of the J2EE agent local audit trail.

PolicyAgent-base/agent_001/logs/debug

Location of all debug files required to debug an agent installation or configuration issue.

PolicyAgent-base/logs/audit/install.log

Location of the file that has the agent install file location. If the installation failed for any reason, you can look at this file to diagnose the issue.
