#######创建DDL同步需要的角色

SQL> @role_setup
   
GGS Role setup script
   
This script will drop and recreate the role GGS_GGSUSER_ROLE
   
To use a different role name, quit this script and then edit the params.sql script to change the gg_role parameter to the preferred name. (Do not run the script.)
   
    
   
You will be prompted for the name of a schema for the GoldenGate database objects.
   
NOTE: The schema must be created prior to running this script.
   
NOTE: Stop all DDL replication before starting this installation.
   
Enter GoldenGate schema name:ogg
