From Oracle GoldenGate 12c onwards, a new feature for security purpose has been introduced known as CREDENTIALSTORE. Using this feature, we can manage the USER ID’s and it’s corresponding passwords which are used by the Oracle GoldenGate processes to interact with the Local Databases for the use of Replication.
So the usernames and passwords will be secured. Upon using this feature the usernames and passwords used in the Oracle GoldenGate process groups or even when we login as an Admin user in the GGSCI, will not be displayed. An optional ALIAS name can be used instead of entering the username and password.
