Database User for Oracle GoldenGate Processes for MySQL

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 support DDL replication, the MySQL user must have privileges to install the database plug-ins. The required permissions for the plug-in is only required with MySQL 5.7. The INSERT privilege is required on the mysql.plugin system table.

  • 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. They must be specified in the Oracle GoldenGate parameter files with the USERID parameter.

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

  • The Oracle GoldenGate user requires the following user privileges.
