end if;
end loop;
end;

可以看到ddl操作成功。
------------------------------------
下面介绍下，如何删除ddl环境：
1、Log in to SQL*Plus as a user that has SYSDBA privileges。
2、Disconnect all sessions that ever issued DDL, including those of Oracle GoldenGate processes, SQL*Plus,
business applications, and any
other software that uses Oracle. Otherwise the database might generate an ORA-04021 error.
3、@ddl_disable.sql
4、@ddl_remove.sql
5、@marker_remove.sql
-----------------------------
最后介绍下ddl功能限制的几点：
1.需关闭回收站功能：
Oracle recycle bin
Because of a known issue in Oracle 10g, the Oracle recycle bin must be turned off to
support Oracle GoldenGate DDL replication. If the recycle bin is enabled, the Oracle
GoldenGate DDL trigger session receives implicit recycle bin DDL operations that cause
the trigger to fail.
When you install the Oracle GoldenGate DDL support objects, the script prompts you to
permit it to purge the recycle bin, and then it will do so automatically if permission is
granted. However, you still must disable the recycle bin manually.
To turn off the recycle bin:
● Oracle 10g Release 2 and later: Set the RECYCLEBIN initialization parameter to OFF.
● Oracle 10g Release 1: Set the _RECYCLEBIN initialization parameter to FALSE.
Consult the database documentation for the correct syntax.
2.DDL语句长度小于2MB
DDL statement length
Oracle GoldenGate measures the length of a DDL statement in bytes, not in characters.
The supported length is approximately 2 MB, allowing for some internal overhead that can
vary in size depending on the name of the affected object and its DDL type, among other
characteristics. If the DDL is longer than the supported size, Extract will issue a warning
and ignore the DDL operation.
3.系统配置：
1).源表结构和目标表结构必须一致
2).复制段必须使用ASSUMETARGETDEFS参数。如果使用 SOURCEDEFS参数(表结构不一致使用此参数)，则将导致复制端进程ABENDED。
