Restricting database user permissions
The database administrator might require that you provide the specific permissions to access the Rule Execution Server or Decision Center database.
Connection to the database, as established in the data source credentials, and any subsequent requests to the database are handled through a database user. This database user is defined by the database administrator and has no relation to the standard Rule Execution Server or Decision Center roles.
The following table gives the list of permissions on operations in the Rule Execution Server database.
