一、Goldengate雙向復制配置
1.1.在進行如下配置之前，先在源數據庫source system（原來的目標數據庫）端
添加輔助的redolog配置：
SQL>alter database add supplemental log data;
SQL>alter system switch logfile;
SQL>alter database force logging;
1.2.在原Source和原Target分別用scott用戶創建一張emp_ogg表
SQL> create table emp_ogg as select * from emp where 1=0; //原source庫建立表但不插入數據
Table created.
單項復制時Source端是EINI_1進程，Target端是RINI_1進程,雙向復制時反之，以便完成兩表的初始化同步，配置如下：
原Source
GGSCI (gc2) 36> ADD REPLICAT RINI_1, SPECIALRUN
REPLICAT added.
GGSCI (gc2) 43> EDIT PARAMS RINI_1
-- GoldenGate Initial Load Delivery

DISCARDFILE ./dirrpt/RINIaa.dsc, PURGE
MAP scott.*, TARGET scott.*;
原Target
GGSCI (oraclelinux54.cuug.net) 10> ADD EXTRACT EINI_1, SOURCEISTABLE
EXTRACT added.
GGSCI (oraclelinux54.cuug.net) 11> INFO EXTRACT *, TASKS

Output to RINI_1:
From Table SCOTT.EMP_OGG:
# inserts: 14 //可以看出兩邊已經同步成功
# updates: 0
# deletes: 0
# discards: 0
1.3.在ogg環境下，添加日志跟蹤：
GGSCI (oraclelinux54.cuug.net) DBLOGIN USERID ogg, PASSWORD ogg
GGSCI (oraclelinux54.cuug.net) ADD TRANDATA scott.* //這里為了試驗方便，我們設置為scott下全部表均設為可同步狀態
2013-08-13 03:21:18 GGS WARNING 109 No unique key is defined for table EMP_OGG. All viable columns will be used to represent the key, but may not guarantee uniqueness. KEYCOLS may be used to define the key.
2013-08-13 03:21:18 GGS WARNING 301 Failed to add supplemental log group on table SCOTT.EMP_OGG due to ORA-01031: insufficient privileges, SQL ALTER TABLE "SCOTT"."EMP_OGG" ADD SUPPLEMENTAL LOG GROUP "GGS_EMP_OGG_74686" ("EMPNO","ENAME","JOB","MGR","HIREDATE","SAL","COMM","DEPTNO") ALWAYS /* GOLDENGATE_DDL_REPLICATION */.
解決辦法：
SQL>alter table emp_ogg add constraint emp_ogg_pk primary key(empno);
SQL> grant alter any table to ogg;
Grant succeeded.
1.4.配置extract
GGSCI (gc2) 71> EDIT PARAMS EORA_1 //編輯前先停止進程
EXTRACT EORA_1
SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
USERID ogg, PASSWORD ogg
EXTTRAIL ./dirdat/aa
TABLE scott.*;
DDL INCLUDE OBJNAME "scott.*"
TRANLOGOPTIONS EXCLUDEUSER ogg //雙向復制關鍵
GGSCI (oraclelinux54.cuug.net) 74> EDIT PARAMS EORA_1 //編輯前先停止進程
EXTRACT EORA_1
SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
USERID ogg, PASSWORD ogg
TRANLOGOPTIONS EXCLUDEUSER ogg
EXTTRAIL ./dirdat/aa
TABLE scott.*;
DDL INCLUDE OBJNAME "scott.*"
GGSCI (雙節點執行)> ADD EXTRACT EORA_1, TRANLOG, BEGIN NOW
注：
ADD EXTRACT EORA_1:添加EXTRACT進程，這就是一直運行，一段停止redo 里的日志就沒人去抓取了
TRANLOG, BEGIN NOW：現在開始同步日志，也可以用異步，那就要另外配置
EXTRACT added.
GGSCI (雙節點執行)> ADD EXTTRAIL ./dirdat/aa, EXTRACT EORA_1, MEGABYTES 5 //添加跟蹤文件給EORA_1用，大小為5M
EXTTRAIL added.
GGSCI (雙節點執行)> START EXTRACT EORA_1
1.5.配置pump進程
GGSCI (gc2) 72> EDIT PARAMS PORA_1 //編輯前先停止進程
EXTRACT PORA_1
SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
PASSTHRU
RMTHOST oraclelinux54.cuug.net, MGRPORT 7809
RMTTRAIL /u01/app/ogg/dirdat/pa
TABLE scott.*;
GGSCI (oraclelinux54.cuug.net) 75> EDIT PARAMS PORA_1 //編輯前先停止進程
EXTRACT PORA_1
SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
PASSTHRU
RMTHOST gc2, MGRPORT 7809
RMTTRAIL ./dirdat/pa
TABLE scott.*;
GGSCI (雙節點執行)> ADD EXTRACT PORA_1, EXTTRAILSOURCE ./dirdat/aa // 告訴PORA_1要傳送哪個路徑下的跟蹤信息
EXTRACT added.
GGSCI (雙節點執行)> ADD RMTTRAIL ./dirdat/pa, EXTRACT PORA_1, MEGABYTES 5 // 表示把捕獲到的信息傳送到遠程的哪個目錄的文件中
RMTTRAIL added.
GGSCI (雙節點執行)> START EXTRACT PORA_1
配置replicate
GGSCI (gc2) 74> EDIT PARAM RORA_1
REPLICAT RORA_1
SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
USERID ogg, PASSWORD ogg
HANDLECOLLISIONS
ASSUMETARGETDEFS
DISCARDFILE ./dirrpt/RORA_aa.DSC, PURGE
DDL INCLUDE ALL
DDLERROR DEFAULT IGNORE RETRYOP MAXRETRIES 3 RETRYDELAY 5
DDLERROR DEFAULT DISCARD
DDLERROR DEFAULT IGNORE RETRYOP
MAP scott.*, TARGET scott.*;
GGSCI (oraclelinux54.cuug.net) 87> EDIT PARAM RORA_1

GGSCI (雙節點執行) 87> ADD REPLICAT RORA_1, EXTTRAIL ./dirdat/pa //表示從哪里提取傳送過來的信息
GGSCI (雙節點執行) 87> START REPLICAT RORA_1
SQL> conn / as sysdba

Grant succeeded.
SQL> conn / as sysdba
Connected.
SQL> grant delete on scott.emp_ogg to ogg;
Grant succeeded.
SQL> grant update on scott.emp_ogg to ogg;
Grant succeeded.
二、配置checkpoint
GGSCI (oraclelinux54.cuug.net) EDIT PARAMS ./GLOBALS
CHECKPOINTTABLE ogg.ggschkpt
GGSCI (oraclelinux54.cuug.net) exit
GGSCI (oraclelinux54.cuug.net) DBLOGIN USERID ogg, PASSWORD ogg
Successfully logged into database.
GGSCI (oraclelinux54.cuug.net) ADD CHECKPOINTTABLE //如果單項復制已經做了，這里不用再添加
應該看到，兩節點的進程都為Running狀態
GGSCI (gc2) 73> info all
Program Status Group Lag Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EORA_1 00:00:00 00:00:02
EXTRACT RUNNING PORA_1 00:00:00 00:00:04
REPLICAT RUNNING RORA_1 00:00:00 00:00:01
GGSCI (oraclelinux54.cuug.net) 88> info all
Program Status Group Lag Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EORA_1 00:00:00 00:00:09
EXTRACT RUNNING PORA_1 00:00:00 00:00:02
REPLICAT RUNNING RORA_1 00:00:00 00:00:05
三、測試雙向傳送結果
3.1.source 到target
Source system
SQL> INSERT INTO emp_ogg VALUES(8000,'HL','CLERK',7902,'12-DEC-80',800,100,20);
1 row created.
SQL> commit;
Commit complete.
SQL> select * from emp_ogg;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------
8000 HL CLERK 7902 12-DEC-80 800 100 20
Target system
SQL> select * from emp_ogg;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- ---------- ---------- --------------------- ---------- ---------- ----------
8000 HL CLERK 7902 1980-12-12 : 00:00:00 800 100 20
3.2target 到 source
Target system
SQL> select * from tcustmer;
CUST NAME CITY ST
---- ------------------------------ -------------------- --
WILL BG SOFTWARE CO. SEATTLE WA
JANE ROCKY FLYER INC. DENVER CO
SQL> insert into tcustmer values ('HL','zai','cuug','en');
1 row created.
SQL> commit;
Commit complete.
Source system
SQL> select * from tcustmer;
CUST NAME CITY ST
---- ------------------------------ -------------------- --
WILL BG SOFTWARE CO. SEATTLE WA
JANE ROCKY FLYER INC. DENVER CO
helei zai cuug en
四、支持DDL復制配置
4.1在兩個節點執行執行DDL同步腳本命令：
先進入goldengate軟件安裝目錄，以SYSDBA身份登錄oracle執行以下腳本，執行腳本過程中，需要輸入的用戶全部是ogg，安裝模式為INITIALSETUP，如果數據字典或者某些內部的包有錯誤，則需要運行catalog.sql和catproc.sql腳本。
SQL>show parameter recyclebin;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
recyclebin string off 必須是off
這里執行第二個腳本@ddl_setup時會報一個recyclebin的錯誤，而且只能在Pfile中修改recyclebin=off后用pfile起庫，執行兩個清除腳本，再重新運行一下腳本
SQL>@marker_setup
SQL>@ddl_setup
SQL>@role_setup
SQL>grant GGS_GGSUSER_ROLE to ogg;
SQL>@ddl_enable
如果某項腳本執行錯誤，需要重新執行時，先要執行清除的腳本：ddl_remove.sql和marker_remove.sql
