In order to use Non Default Databases you will first need to setup the Database and ambari provides various "*.sql" files which has the DDL to create/setup the DB and create various tables in it.

These SQL files can be found inside the "/var/lib/ambari-server/resources" directory on ambari server.

More detailed instructions can be found here:

MySQL: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.5/bk_ambari-administration/content/using_amba...

Oracle: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.5/bk_ambari-administration/content/using_amba...

Once the Database is setup and we execute the DDL on the DB side then while runnign the "ambari-server setup" command at some point it will ask for "Advanced Database Configuration" there we can enter the remote Database Hostname & Port . The setup wizard itself will ask for the DB username & password Schema name etc.

Suppose you want to setup a Remotely running Oracle Server ()assuming it is running on remote host "oracledb.example.com" on port 1521) for your Ambari Server.

Then you will need to do this:

Step1). Refer to the Ambari Doc to know how run the DDL on the Remote Database.

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.5/bk_ambari-administration/content/using_amba...

Step2). On the ambari Server Host run the ambari setup as following:

Basically when Ambari Setup wizard asks for "Enter advanced database configuration [y/n] (n)?" Then enter 'y' and proceed

Example:

# ambari-server setup
Using python  /usr/bin/python
Setup ambari-server
Checking SELinux...
SELinux status is 'enabled'
SELinux mode is 'permissive'
WARNING: SELinux is set to 'permissive' mode and temporarily disabled.
OK to continue [y/n] (y)? y
Customize user account for ambari-server daemon [y/n] (n)? n
Adjusting ambari-server permissions and ownership...
Checking firewall status...

Do you want to change Oracle JDK [y/n] (n)? n

WARNING: Before starting Ambari Server, you must run the following DDL against the database to create the schema: /var/lib/ambari-server/resources/Ambari-DDL-Oracle-CREATE.sql'
Proceed with configuring remote database connection properties [y/n] (y)? y
