Installing the DDL objects:1、Run the @marker_setup.sql script. This script installs support for the Oracle GoldenGatemarker system, which is required for DDL support. You will be prompted for the nameof the Oracle GoldenGate schema.drop trigger ggs_ddl_trigger_before;grant create table,create view,create sequence to ogg;2、Run the @ddl_setup.sql script Script that installs the Oracle GoldenGate DDL extraction andreplication objects. (Oracle installations)3、Run the @role_setup.sql script. This script drops and creates the role needed for DDLsynchronization. It grants DML permissions on the Oracle GoldenGate DDL objects4、Grant the role to all Oracle GoldenGate Extract users. You may need to make multiplegrants if the processes have different user names.Run the @ddl_enable.sql script to enable the DDL trigger.5、To improve the performance of the DDL trigger, make the ddl_pin script part of the databasestartup. It must be invoked with the Oracle GoldenGate DDL user name, as in:@?/rdbms/admin/dbmspool.sqlSQL> @ddl_pin oggTo improve the performance of the DDL trigger This script pins the PL/SQL package that is used by the trigger into memory. If executingthis script from SQL*Plus, connect as SYSDBA from the Oracle GoldenGate home directory.This script relies on the Oracle dmbs_shared_pool system package, so install that packagebefore using ddl_pin.配置Target：
