Using Ambari with Oracle

This page outlines the step-by-step instructions to install Apache Ambari with Oracle 19c as the backend database.

Prerequisites

Before you setup:

Ensure you have access to the Oracle 19c database (CDB + PDB setup).
Install Oracle JDBC drivers (ojdbc11.jar).
Create required users and grant permissions for Ambari.
Confirm Ambari is installed and Java is configured on the cluster.

Download and Install Oracle JDBC Driver

Perform the following steps on the Ambari Server host.

Download JDBC Driver.
1. Navigate to the Oracle JDBC Driver Download Page to download the JDBC Driver.
2. Download the JDBC driver compatible with Oracle Database 19c:
  - Select Oracle Database 23ai (23.8.0.25.04) JDBC Driver.
  - Download ojdbc11.jar
Copy the driver to Java shared directory.

Bash
    
 
cp ojdbc11.jar /usr/share/java/ chmod 644 /usr/share/java/ojdbc11.jar
Copy

Create Ambari Database and User in Oracle

Perform the following steps on the Oracle host using sqlplus.

Connect to SYSBDA.

Bash
    
 
sqlplus / as sysdba
Copy

Switch to the Pluggable Database (PDB).

Bash

Configure JDBC Driver with Ambari

Run the following command on the Ambari Server host.

Bash

Copy

Ambari Server Schema Load

Navigate to Oracle sqlplus and run the queries of /var/lib/ambari-server/resources/Ambari-DDL-Oracle-CREATE.sql.

Bash
    
 
SQL> conn ambari/bigdata@ORCLPDB1Connected.SQL> SELECT table_name, owner FROM all_tablesORDER BY   owner, table_name;
Copy

Verify all the tables.

For new installations, run the following script.

Bash
    
 
/var/lib/ambari-server/resources/Ambari-DDL-Oracle-CREATE.sql
Copy

This script should be executed within the SQL*Plus (sqlplus) shell.

Bash
    
 
SQL> @/var/lib/ambari-server/resources/Ambari-DDL-Oracle-CREATE.sqlTable created.Table created...1 row created.1 row created.....Index created.Index created.
Copy

Run the following command on the Ambari Server host.

Bash
    
 
ambari-server setup --jdbc-db=oracle --jdbc-driver=/usr/share/java/ojdbc11.jar
Copy

Start Ambari server

Run the following script.

Bash
    
 
[root@odpnew-1-test ~]# ambari-server startUsing python  /usr/bin/pythonStarting ambari-serverAmbari Server running with administrator privileges.Organizing resource files at /var/lib/ambari-server/resources...Ambari database consistency check started...Server PID at: /var/run/ambari-server/ambari-server.pidServer out at: /var/log/ambari-server/ambari-server.outServer log at: /var/log/ambari-server/ambari-server.logWaiting for server start.........................................Server started listening on 8080DB configs consistency check: no errors and warnings were found.Ambari Server 'start' completed successfully.
Copy

Verify Ambari logs (ambari-server.{log,out}) for errors and ensure users can access the Ambari Web UI.
Register hosts and provide repo details to set up the cluster.
