The following pre-requisites need to be done on your system before you run the RCU for creating schemas –

• You must create an Oracle Database Instance (11g Release 1 or 2).
  
• All the below required DB parameters need to be updated and these are only specific to RCU. Execute the below given SQL query using TOAD Editor/SQL Plus before you run the RCU installation.
  

 

alter system set open_cursors=500 scope=spfile

alter system set processes=500 scope=spfile

alter system set sessions=500 scope=spfile

 

 

 

 

This section elaborates the step-by-step procedure to create schemas in the database –

Step 1:

• Unzip the RCU installable file to a directory (Say, rcuHome).

Step 12:

• The Completion Summary Screen appears, indicating the successful creation of schemas for Oracle WebCenter 11g and Oracle UCM 11g.
  
• Click Close to exit.
  

   

1. JDK Installation
   

The JDK must be installed on your system before you install Oracle WebLogic Server. It is recommended that you use the Sun JDK if you are installing in a development environment. Typically, this environment provides a more relaxed security configuration and enables you to auto-deploy applications. In a development environment, boot.properties is used for user names and passwords and polling is used for application deployment.

If you are installing in a production environment, it is recommended that you use the Oracle JRockit JDK. Production environments are for applications running in their final form. Full security is enabled and applications may be clustered or use other advanced features. In this mode, user names and passwords are required and polling is not used for application deployment.

This section elaborates the step-by-step procedure to install Sun JDK –

Step 1:

• Navigate to the directory where you want to install the software. (Say, /usr/local/apps). In this installation, Sun JDK installable file is placed at the same location where you want to install the software.
  

   

• Change the permission of the file you downloaded to be executable. Open a terminal window and enter the following command:
  

 

chmod a+x jdk-6u26-linux-x64.bin

• Verify that you have permission to execute the file. Enter the following command:
  

   

  ls –l
  

   

Step 2:

• Run the JDK executable file. Enter the following command:
  

  
  ./jdk-6u26-linux-x64.bin
  

   

 

 

 

 

Step 3:

• You will be prompted to ‘Press Enter to continue’. Press ‘Enter’ to complete the installation. In this installation, Sun JDK is installed in the /usr/local/apps/jdk1.6.0_26 directory.
