The next screen will display the instances on the Master Server. Click the column next to “DBA User Account”.
The below popup will appear for the user to input the Password for the Oracle User “System”
If all the Oracle instances have the same password for the user “System”, the user can enter the password once and click on the “Apply to All” option. If the Oracle instances have different password for the user “System”, the user will have to input the password for each instances independently
After the user inputs the system password for the Oracle instances and clicks “OK”, RHA will auto discover the database files for each instance. The user can verify the same and click next.
The following screen will be Scenario Properties followed by “Host” and “Switchover” Properties.
