1.1. Using Ambari with Oracle

To set up Oracle for use with Ambari:

On the Ambari Server host, install the appropriate JDBC.jar file.
1. Download the Oracle JDBC (OJDBC) driver from http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html.
2. For Oracle Database 11g: select Oracle Database 11g Release 2 drivers > ojdbc6.jar.
3. For Oracle Database 12c: select Oracle Database 12c Release 1 drivers > ojdbc7.jar.
4. Copy the .jar file to the Java share directory. For example:
  cp ojdbc7.jar /usr/share/java/
5. Make sure the .jar file has the appropriate permissions. For example:
  chmod 644 /usr/share/java/ojdbc7.jar
Create a user for Ambari and grant that user appropriate permissions.
For example, using the Oracle database admin utility, run the following commands:
# sqlplus sys/root as sysdba
CREATE USER <AMBARIUSER> IDENTIFIED BY <AMBARIPASSWORD> default tablespace “USERS” temporary tablespace “TEMP”;
GRANT unlimited tablespace to <AMBARIUSER>;
GRANT create session to <AMBARIUSER>;
GRANT create TABLE to <AMBARIUSER>;
GRANT create SEQUENCE to <AMBARIUSER>;
QUIT;
Where <AMBARIUSER> is the Ambari user name and <AMBARIPASSWORD> is the Ambari user password.
Load the Ambari Server database schema.
1. You must pre-load the Ambari database schema into your Oracle database using the schema script.
  sqlplus <AMBARIUSER>/<AMBARIPASSWORD> < Ambari-DDL-Oracle-CREATE.sql
2. Find the Ambari-DDL-Oracle-CREATE.sql file in the /var/lib/ambari-server/resources/ directory of the Ambari Server host after you have installed Ambari Server.
When setting up the Ambari Server, select Advanced Database Configuration > Option [2] Oracle and respond to the prompts using the username/password credentials you created in step 2.
