Oracle Real Application Clusters (RAC) is an option for the Oracle Database for clustering and high availability in Oracle database environments. In Oracle RAC environment, some of the commands used in
oracle.sql is considered inefficient (refer to Setting up with Oracle ). Therefore, the product has a separate SQL script
oracle_rac.sql for Oracle RAC. The Oracle RAC-friendly script is located in
dbscripts folder together with other
To test products on a Oracle RAC, please, rename
oracle.sql before running
1. Set environment variables
ORACLE_HOME, PATH, ORACLE_SID with the corresponding values
/oracle/app/oracle/product/11.2.0/dbhome_1, $PATH:$ORACLE_HOME/bin, orcl1.
2. Connect to Oracle using SQL*Plus as sysdba.
3. Create a database user and grant privileges to the user as shown below:
4. Exit from the SQL*Plus session by typing the "quit" command.
Setup Configuration File
1. Edit the default database configuration defined in the
master-datasources.xml file located at
$CARBON_HOME/repository/conf/datasources directory as follows. Both the database configurations in
user-mgt.xml refer this data source.
Replace these settings with your own custom values.
The database configuration options
- url - The URL of the database.
- username - The name of the database user.
- password - The password of the database user.
- driverClassName - The class name of the database driver.
- maxActive - The maximum number of active connections that can be allocated from this pool at the same time or negative for no limit.
- maxWait - The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception or <= 0 to wait indefinitely.
- minIdle - The minimum number of active connections that can remain idle in the pool without extra ones being created or 0 to create none.
Copy JDBC Driver
Copy the Oracle JDBC libraries to
<PRODUCT_HOME>/repository/components/lib . For example,
- $ORACLE_HOME/jdbc/lib/ojdbc14.jar .
Note: Remove old database driver from
<PRODUCT_HOME>/repository/components/dropins ,when you upgrade the database driver.
Create Database Tables
Database tables can be created either manually by running scripts or automatically by using start-up parameters.
Database tables can be created manually by logging in to the created database and running the following scripts in SQL*Plus:
Start the product.
Using Start-up Parameters
- For Windows users:
To create the database tables when starting the product for the first time.
- For Linux Users
