3. Ambari

On the Ambari Server machine, install the Oracle JDBC .jar file:
1. Download the Oracle JDBC (OJDBC) driver from http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html.
  Select Oracle Database 11g Release 2 - ojdbc6.jar
2. Copy the .jar file to the Java share directory
```
cp ojdbc6.jar /usr/share/java
```
3. Make sure the .jar file has the appropriate permissions - 644.

Create the Ambari user, password, and tablespace, and grant the account database permissions:

# sqlplus sys/root as sysdba
SQL> create user $AMBARIUSER identified by $AMBARIPASSWORD default 
                 tablespace "USERS" temporary tablespace "TEMP";
SQL> grant unlimited tablespace to $AMBARIUSERR;
SQL> grant create session to $AMBARIUSER;
SQL> grant create table to $AMBARIUSER;
SQL> quit;

Where $AMBARIUSER is the Ambari user name and $AMBARIPASSWORD is the Ambari user password.

Load the Ambari Server schema:
- To set up Ambari Server to load the schema automatically:
  1. Download the Oracle Instant Client (for Linux x-86 or x86-64), Basic and the Instant Client Package - SQL*Plus, version 11.2.0.3.0, on the Ambari Server host.
    For information on the Oracle Database Instant Client, see here. To download the x86 client, see here. To download the x86-64 client, see here.
  2. Extract the zip files on your Ambari Server
    mkdir /home/oracle cd /home/oracle unzip /tmp/instantclientsqlpluslinux.x6411.2.0.3.0.zip unzip /tmp/instantclientbasiclinux.x6411.2.0.3.0.zip
  3. Update your PATH and LD_LIBRARY_PATH variables. For example, in BASH:
    export PATH=/home/oracle/instantclient_11_2:${PATH} export LD_LIBRARY_PATH=/home/oracle/instantclient_11_2:${LD_LIBRARY_PATH}
- To load the schema manually, create the Ambari Server schema by running a script:
```
sqlplus $AMBARIUSER/$AMBARIPASSWORD < 
/var/lib/ambari-server/resources/Ambari-DDL-Oracle-CREATE.sql
                    
```
  The file Ambari-DDL-Oracle-CREATE.sql is found in the /var/lib/ambari-server/resources/ directory of the Ambari Server machine, once you have completed the Set Up the Bits step in the install process. .
