1.开始配置OGG支持DDL复制(在source端操作)
1.1 赋予权限
SQL> conn /as sysdba
已连接。
SQL> grant execute on utl_file to ggs;
1.2 修改全局配置文件添加ggschema
GGSCI (WIN-GM5PVS1CILH) 18> edit param ./GLOBALS
GGSCI (WIN-GM5PVS1CILH) 19> view param ./GLOBALS
ggschema ggs
GGSCI (WIN-GM5PVS1CILH) 20>
1.3 运行相关sql脚本 及修改参数
C:\Users\Administrator>cd C:\ora11g\product\ogg_src
C:\ora11g\product\ogg_src>sqlplus /nolog
SQL> conn /as sysdba
已连接。
#第一个sql脚本

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 scri
pt 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.

Enter GoldenGate schema name:ggs
已写入 file role_setup_set.txt
PL/SQL 过程已成功完成。
Role setup script complete
Grant this role to each user assigned to the Extract, GGSCI, and Manager processes, by using the following SQL command:
GRANT GGS_GGSUSER_ROLE TO <loggedUser>
where <loggedUser> is the user assigned to the GoldenGate processes.
SQL> grant ggs_ggsuser_role to ggs;
授权成功。

2.source端修改extract进程的params文件，添加"ddl include all"参数，重启extract进程
2.1 查看添加后的参数
GGSCI (WIN-GM5PVS1CILH) 40> view param eora_t1
extract eora_t1
setenv (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
ddl include all
userid ggs@orcl_w,password ggs
exttrail dirdat/sp
table scott.*;
2.2 重启 EXTRACT 进程
GGSCI (WIN-GM5PVS1CILH) 41> stop extract eora_t1
Sending STOP request to EXTRACT EORA_T1 ...
Request processed.
GGSCI (WIN-GM5PVS1CILH) 42> start extract eora_t1

3. target端修改replicat进程的params文件，添加"ddl include all"和"ddlerror default ignore retryop maxretries 3 retrydelay 5" 参数，重启replicat进程
3.1 查看添加后的参数
GGSCI (Oracle02 as ggt@orcl) 11> edit param rora_t1
GGSCI (Oracle02 as ggt@orcl) 12> view param rora_t1
