Requirements for the database user for Oracle GoldenGate processes are as follows:

• Create a database user that is dedicated to Oracle GoldenGate. It can be the same user for all the Oracle GoldenGate processes that must connect to a database.

• To preserve the security of your data, and to monitor Oracle GoldenGate processing accurately, do not permit other users, applications, or processes to log on as, or operate as, the Oracle GoldenGate database user.

• Keep a record of the database users credentials to set up database connection from Oracle GoldenGate. These credentials are required when setting up the USERIDALIAS for database login (DBLOGIN) from Oracle GoldenGate.

• The Oracle GoldenGate user requires read access to the INFORMATION_SCHEMA database.

• The Oracle GoldenGate user requires the following user privileges.
