现在将Target升级到与源端一样的版本
备份Target ogg安装目录：
[root@linuxidc2 /]# cp -R ogg/ /database/
查看Source端抽取进程是否active：
GGSCI (linuxidc1) 6> send extract ext1 logend
Sending LOGEND request to EXTRACT EXT1 ...
YES.
GGSCI (linuxidc1) 7> send extract ext2 logend
Sending LOGEND request to EXTRACT EXT2 ...
YES.
发现没有抽取和传输数据，可以停止进程
查看Target端复制进行是否active：
GGSCI (linuxidc2) 2> send replicat rep1 status
Sending STATUS request to REPLICAT REP1 ...
Current status: At EOF

在target数据库中：
Installing the DDL objects:
1、Run the @marker_setup.sql script. This script installs support for the Oracle GoldenGate
marker system, which is required for DDL support. You will be prompted for the name
of 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 and
replication objects. (Oracle installations)
3、Run the @role_setup.sql script. This script drops and creates the role needed for DDL
synchronization. It grants DML permissions on the Oracle GoldenGate DDL objects
4、Grant the role to all Oracle GoldenGate Extract users. You may need to make multiple
grants 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 database
startup. It must be invoked with the Oracle GoldenGate DDL user name, as in:
@?/rdbms/admin/dbmspool.sql
SQL> @ddl_pin ogg
To improve the performance of the DDL trigger
This script pins the PL/SQL package that is used by the trigger into memory. If executing
this 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 package
before using ddl_pin.
