Overview The process of User password change in the Data Guard environment is not the same as the normal process. Generally, the effect of password change is applied in both the data dictionary and password file. So, when we change the password on the Primary Server, the data dictionary is changed on all servers but the physical password file is not updated automatically. For this reason, we need to copy the password file from the Primary Server to all the Secondary Servers i.e. Standby Servers. If we change the password only on the Primary Server and not transferred or applied to the Standby Server, then the Primary Server stops transferring archive logs to the Standby and you will see the error in the alert log file. Let’s start to learn how to change the password in the data guard environment. I recommended applying this process for Oracle Database 12c Release 1 and Release 2 and for Oracle Database 19c and 21c please check this link . Lab Environment Primary Server Standby Server O

Overview According to Oracle, Oracle Database 12c is ‘the first database designed for the cloud’; the suffix ‘c’ stands for the cloud. There are many new features in this release such as multitenant architecture, pluggable database, in-memory, etc. The multitenant architecture is designed to simplify consolidation without requiring any changes to the applications. The rapid provisioning and portability capabilities are enhanced by the pluggable databases. Another new feature is in-memory makes it the first Oracle database to offer real-time analytics.
