9 Creating a Domain for an Enterprise Deployment

This chapter describes how to create a domain using the Configuration Wizard, Oracle WebLogic Server Administration Console and Oracle Enterprise Manager Fusion Middleware Control. The topology you are creating dictates the number of domains you need to create. Once the initial domain has been created, it can be extended with other products as described later on in this book.

Note:

Oracle strongly recommends that you read the release notes for any additional installation and deployment considerations prior to starting the setup process.

This chapter contains the following sections.

9.1 Overview of Creating a Domain

9.4 Running the Configuration Wizard to Create a Domain

Run the WebLogic Configuration Wizard on IDMHOST1. In later chapters you will extend these domains to include the components of your topology.

To create a domain:

  1. Ensure that the database where you installed the repository is running. For Oracle RAC databases, all instances should be running, so that the validation check later in the procedure is more reliable.

  2. Change directory to the location of the Configuration Wizard. This is within ORACLE_COMMON_HOME.

    cd ORACLE_COMMON_HOME/common/bin
    
  3. Start the Oracle Fusion Middleware Configuration Wizard:

    ./config.sh
    
  4. On the Welcome screen, select Create a New WebLogic Domain, and click Next.

  5. On the Select Domain Source screen, select the following products:

    • Oracle Entitlements Server for Admin Server [iam]

    • Oracle Enterprise Manager [oracle_common]

    • Oracle Platform Security Service [iam]

    • Oracle Directory Services Manager [oud] (if using Oracle Unified Directory)

    • Oracle JRF [oracle_common]

    Click Next.

  6. On the Specify Domain Name and Location screen, enter

    • Domain name: IDMDomain

    • Domain location: ORACLE_BASE/config/domains

    • Application location: ASERVER_HOME/applications

    Ensure that the domain directory matches the directory and shared storage mount point recommended in Section 4.3, "Shared Storage Recommendations for Enterprise Deployments."

    Click Next.

  7. On the Configure Administrator Username and Password screen, enter the username (default is weblogic) and password to be used for the domain's administrator. For example:

    • Name: weblogic

    • User Password: password for weblogic user

    • Confirm User Password: password for weblogic user

    • Description:This user is the default administrator.

    Click Next.

  8. On the Configure Server Start Mode and JDK screen, do the following:

    • For WebLogic Domain Startup Mode, select Production Mode.

    • For JDK Selection, select JRockit SDK

    Click Next.

    Note:

    The next step and all steps through Step 12, "On the Test Component Schema," are only relevant if the domain being created is IDMDomain or OIMDomain.

  9. On the Configure JDBC Component Schema screen, select the following:

    • OPSS Schema

    For the Oracle RAC configuration for component schemas, select Convert to GridLink.

    Click Next.

  10. The Gridlink RAC Component Schema screen appears. In this screen, enter values for the following fields, specifying the connect information for the Oracle RAC database that was seeded with RCU.

    • Driver: Select Oracle's driver (Thin) for GridLink Connections,Versions:10 and later.

    • Select Enable FAN.

    Do one of the following:

    • If SSL is not selected for ONS notifications to be encrypted, deselect SSL.

    • Select SSL and provide the appropriate wallet and wallet password.

    • Service Listener: Enter the SCAN address and port for the RAC database being used. You can identify this address by querying the parameter remote_listener in the database:

      SQL>show parameter remote_listener;
      NAME            TYPE   VALUE
      -------------------------------------------------------------
      remote_listener string DB-SCAN.mycompany.com:1521
      

      Note:

      • For Oracle Database 11g Release 1 (11.1), use the virtual IP and port of each database instance listener, for example: DBHOST1-vip.mycompany.com (port 1521) and DBHOST2-vip.mycompany.com (port 1521)

      • For Oracle Database 10g, use multi data sources to connect to an Oracle RAC database. For information about configuring multi data sources see Appendix B, "Using Multi Data Sources with Oracle RAC."

    • ONS Host: Enter the SCAN address for the Oracle RAC database and the ONS remote port, as reported by the database when you invoke the following command:

      srvctl config nodeapps -s
      ONS exists: Local port 6100, remote port 6200, EM port 2016
      

    Note:

    For Oracle Database 11g Release 1 (11.1), use the hostname and port of each database's ONS service, for example: DBHOST1.mycompany.com (port 6200) and DBHOST2.mycompany.com (port 6200)

    Enter the following RAC component schema information:

    Table 9-3 RAC Component Schema Information

    Schema Name Service Name User Name Password

    OPSS Schema

    oesedg.mycompany.com

    EDG_OPSS

    password


    If you prefer to use RAC Multi Data Sources, see Appendix B, "Using Multi Data Sources with Oracle RAC."

    Click Next.

  11. In the Test JDBC Data Sources screen, confirm that all connections are successful. The connections are tested automatically. The Status column displays the results. If all connections are not successful, click Previous to return to the previous screen and correct your entries.

    Click Next when all the connections are successful.

  12. On the Test Component Schema screen, the Wizard attempts to validate the data sources. If the data source validation succeeds, click Next. If it fails, click Previous, correct the problem, and try again.

  13. On the Select Optional Configuration screen, select the following:

    • Administration Server

    • Managed Servers, Clusters and Machines

    Click Next.

    Click Next.

  15. On the Configure Managed Servers screen, click Next.

  16. On the Configure Clusters screen, click Next.

  17. On the Configure Machines screen, click the Unix Machine tab and then click Add to add the following machine. The machine name does not need to be a valid host name or listen address, it is just a unique identifier of a node manager location:

    • Name: ADMINHOST

    • Node manager listen address: ADMINVHN.mycompany.com

  18. Click Next.

  19. On the Assign Servers to Machines screen, assign servers to machines as follows:

    • ADMINHOST: AdminServer

    Where ADMINHOST is the name value entered in Step 17, for example:

    ADMINVHN.mycompany.com

    Click Next.

  20. On the Configuration Summary screen, validate that your choices are correct, then click Create.

  21. On the Create Domain screen, click Done.

9.5 Post-Configuration and Verification Tasks

After configuring the domain with the configuration Wizard, follow these instructions for post-configuration and verification.

This section includes the following topics:

9.5.1 Creating boot.properties for the WebLogic Administration Servers

Create a boot.properties file for the Administration Server on the host IDMHOST1. If the file already exists, edit it. The boot.properties file enables the Administration Server to start without prompting you for the administrator username and password.

For each Administration Server:

  1. Create the following directory structure.

    mkdir -p ASERVER_HOME/servers/AdminServer/security
    
  2. In a text editor, create a file called boot.properties in the last directory created in the previous step, and enter the username and password in the file. For example:

    username=weblogic
    password=password for weblogic user
    
  3. Save the file and close the editor.

Note:

The username and password entries in the file are not encrypted until you start the Administration Server, as described in Section 9.5.4, "Updating the Node Manager Credentials." For security reasons, minimize the time the entries in the file are left unencrypted. After you edit the file, start the server as soon as possible so that the entries are encrypted.

9.5.2 Associate the Domain with the Existing OPSS Policy Store

Before starting your domain for the first time, you must associate the domain with the OPSS policy store in the database.

Before re-association, back up the following configuration files:

  • ASERVER_HOME/config/config.xml

  • ASERVER_HOME/config/fmwconfig/jps-config.xml

  • ASERVER_HOME/config/fmwconfig/system-jazn-data.xml

Back up the boot.properties file for the Administration Server in the following directory:

ASERVER_HOME/servers/AdminServer/security

To associate the first domain with the OPSS security store use the following command:

ORACLE_COMMON_HOME/common/bin/wlst.sh IAM_ORACLE_HOME/common/tools/configureSecurityStore.py -d ASERVER_HOME -c IAM -m create -p opss_schema_password

Validate that the above commands have been successful by issuing the command:

ORACLE_COMMON_HOME/common/bin/wlst.sh IAM_ORACLE_HOME/common/tools/configureSecurityStore.py -d ASERVER_HOME -m validate

9.5.3 Starting Node Manager on IDMHOST1 and IDMHOST2

Perform these steps to start Node Manager on IDMHOST1 and IDMHOST2:

  1. Run the startNodeManager.sh script located under the WL_HOME/server/bin directory.

  2. Run the setNMProps.sh script to set the StartScriptEnabled property to true:

    cd IAM_MW_HOME/oracle_common/common/bin
    ./setNMProps.sh
    

    Note:

    You must use the StartScriptEnabled property to avoid class loading failures and other problems.

  3. Stop the Node Manager by killing the Node Manager process.

  4. Start Node Manager by running the startNodeManager.sh script located under the IAM_MW_HOME/wlserver_10.3/server/bin directory.

9.5.4 Updating the Node Manager Credentials

You start the Administration Server by using WLST and connecting to Node Manager. The first start of the Administration Server with Node Manager, however, requires that you change the default username and password that the Configuration Wizard sets for Node Manager. Therefore you must use the start script for the Administration Server for the first start. Follow these steps to start the Administration Server using Node Manager. Setting the memory parameters is required only for the first start operation.

Setting Memory Parameters

To edit the setDomainEnv.sh file to change memory allocation setting:

  1. Open the setDomainEnv.sh file located in the following directory using a text editor:

    /u01/oracle/config/domains/IDMDomain/bin
    
  2. Change the following memory allocation:

    WLS_MEM_ARGS_64BIT="-Xms512m -Xmx512m
    

    To

    1024m and 3072m
    

    For example:

    WLS_MEM_ARGS_64BIT="-Xms1024m -Xmx3072m"
    
  3. Start the Administration Server using the start script in the domain directory.

    cd ASERVER_HOME/bin
    ./startWebLogic.sh
    

Updating Node Manager Credentials

Use the Administration Console to update the Node Manager credentials on the IDM domain.

To update Node Manager's credentials:

  1. Log into the administration console.

    1. In a browser, go to the listen address for the domain. For example:

      http://ADMINVHN.mycompany.com:7001/console where 7001 is WLS_ADMIN_PORT, as described in Section A.3, "Port Mapping."

    2. Log in as the administrator.

    3. Click Lock and Edit.

    4. Click domain_name.

    5. Select Security tab then General tab.

    6. Expand Advanced Options.

    7. Enter a new username for Node Manager or make a note of the existing one and update the Node Manager password.

    8. Click Save.

    9. Click Activate Changes.

  2. Stop the WebLogic Administration Server by issuing the command stopWebLogic.sh located under the ASERVER_HOME/bin directory.

  3. Start WLST and connect to the Node Manager with nmConnect and the credentials you just updated. Then start the WebLogic Administration Server using nmStart.

    cd ORACLE_COMMON_HOME/common/bin
    ./wlst.sh
    

    Once in the WLST shell, execute the following commands:

    nmConnect('Admin_User','Admin_Password', 'ADMINHOST1','Port',
      domain_name','ASERVER_HOME')
    nmStart('AdminServer')
    

    where Port is NMGR_PORT in Section A.3, "Port Mapping.", domain_name is the name of the domain and Admin_User and Admin_Password are the Node Manager username and password. For example:

    nmConnect('weblogic','password', 'IDMHOST1','5556',
      'IDMDomain','ASERVER_HOME')
    nmStart('AdminServer')
    

9.5.5 Enabling Exalogic Optimizations

Perform these steps to enable Exalogic optimizations:

  1. Log in to the Oracle WebLogic Server Administration Console.

  2. Select IDMDomain in the left navigation pane.

  3. Click Lock & Edit.

  4. On the Settings page, click the General tab.

  5. Select Enable Exalogic Optimizations, and click Save and Activate Changes.

  6. Restart the Administration server.

9.5.6 Enabling WebLogic Plug-in

In an enterprise deployment, Oracle WebLogic Server is fronted by a Web server. The Web server is, in turn, fronted by a load balancer, which performs SSL translation. In order for internal loopback URLs to be generated with the https prefix, Oracle WebLogic Server must be informed that it receives requests through a Proxy Web Server.

The plug-in can be set at either the domain, cluster, or Managed Server level. Because all requests to Oracle WebLogic Server are through the Web server plug-in, set it at the domain level.

To do this perform the following steps:

  1. Log in to the Oracle WebLogic Server Administration Console at http://ADMINVHN.mycompany.com/console.

  2. Click Lock and Edit.

  3. Click domain_name, for example: IDMDomain in the Domain Structure Menu.

  4. Click the Configuration tab.

  5. Click the Web Applications sub tab.

  6. Select WebLogic Plugin Enabled.

  7. Click Save and Activate the Changes.

9.5.7 Validating the WebLogic Administration Server

Perform these steps to ensure that the Administration Server is properly configured:

  1. In a browser, go to the Oracle WebLogic Server Administration Console at the URL:

    http://ADMINVHN.mycompany.com:7001/console, where 7001 is WLS_ADMIN_PORT, as described in Section A.3, "Port Mapping."

  2. Log in as the WebLogic administrator that you created in boot.properties file, for example: weblogic.

  3. Check that you can access Oracle Enterprise Manager Fusion Middleware Control at http://ADMINVHN.mycompany.com:7001/em.

  4. Log in to Oracle Enterprise Manager Fusion Middleware Control as the WebLogic administrator, for example: weblogic.

9.5.8 Disabling Host Name Verification for the Oracle WebLogic Administration Server

This step is required if you have not set up the appropriate certificates to authenticate the different nodes with the Administration Server. (See Chapter 13, "Setting Up Node Manager for an Enterprise Deployment.") If you have not configured the server certificates, you will receive errors when managing the different WebLogic Servers. To avoid these errors, disable host name verification while setting up and validating the topology, and enable it again once the EDG topology configuration is complete as described in Chapter 13, "Setting Up Node Manager for an Enterprise Deployment."

Perform these steps to disable host name verification:

  1. Go to the Oracle WebLogic Server Administration Console at: http://ADMINVHN.mycompany.com:7001/console

  2. Log in as the user weblogic, using the password you specified during the installation.

  3. Click Lock and Edit.

  4. Expand the Environment node in the Domain Structure window.

  5. Click Servers. The Summary of Servers page appears.

  6. Select AdminServer(admin) in the Name column of the table. The Settings page for AdminServer(admin) appears.

  7. Click the SSL tab.

  8. Click Advanced.

  9. Set Hostname Verification to None, if it is not already set.

  10. Click Save.

  11. Click Activate Changes.

9.5.9 Stopping and Starting the WebLogic Administration Server

Stop the Administration Server as described in Section 16.1, "Starting and Stopping Oracle Identity Management Components."

Note:

Admin_User and Admin_Password are only used to authenticate connections between Node Manager and clients. They are independent from the server administration ID and password and are stored in the ASERVER_HOME/config/nodemanager/nm_password.properties file.

9.6 Testing Manual Failover the WebLogic Administration Server

Test failover of the Administration Server to IDMHOST2 and then back to IDMHOST1, as described in Section 16.9, "Manually Failing Over the WebLogic Administration Server."

9.7 Backing Up the WebLogic Domain

Back up the Middleware home, the database and the WebLogic domain as described in Section 16.6, "Backing Up the Oracle IDM Enterprise Deployment."
