When have a two node RAC setup as a primary DB and two node RAC setup as standby database. We have enable data Guard broker configuration for this environment.

PROBLEM CAUSE

When we change the sys password in the primary database using the alter system command, it updates the password file in the ORACLE_HOME of the primary database, it doesn’t update password file in the standby database.

SOLUTION è Changing SYS Password in the Data Guard environment

While changing the sys password in the Primary database. You have manually copy the password file to the standby database. If it is RAC environment, then make sure that you place the file in both the ORACLE_HOME.

In Oracle 11g, Oracle has come up with case-sensitive option. It means passwords are case-sensitive. It is dynamic parameter and it change modified easily. this function available from oracle 11gR1 onwards.
