OGG DDL 双向同步

1. 环境说明。
续单向DDL同步。 再把目标端的DDL也给开启来。

2. 确认源库处于归档模式。

SQL> archive log list;Database log mode              Archive ModeAutomatic archival             EnabledArchive destination            /home/oracle/archivelogOldest online log sequence     3Next log sequence to archive   5Current log sequence           5

3. 确认源库为FORCE_LOGGIN。

SQL> alter database force logging;Database altered.SQL> select force_logging from v$database;FOR---YES

4. 确认源库打开辅助日志。

SQL> select supplemental_log_data_min from v$database;SUPPLEME--------YES

5. 源库关闭回收站。

SQL> show parameter recyclebinNAME                                 TYPE        VALUE------------------------------------ ----------- ------------------------------recyclebin                           string      onSQL> alter system set recyclebin=off;System altered.SQL> show parameter recyclebinNAME                                 TYPE        VALUE------------------------------------ ----------- ------------------------------recyclebin                           string      OFF

6.  保证字符集一致。
7. UNDO设置

SQL> alter system set undo_retention=86400;System altered.

8. 安装DDL_OBJETS

9. MGR配置
源端：
增加一行内容：

PURGEOLDEXTRACTS /home/oracle/gg/trails/w2*, USECHECKPOINTS, MINKEEPFILES 10

目标端：
增加一行内容：

PURGEOLDEXTRACTS /home/oracle/gg/trails/w2*, USECHECKPOINTS, MINKEEPFILES 10

10. ./GLOBALS配置（目标端）

GGSCI (GOLDENGATE1) 2> edit params ./GLOBALSGGSCHEMA goldengateCHECKPOINTTABLE goldengate.chkpointGGSCI (GOLDENGATE1) 3> dblogin userid goldengate, password goldengateSuccessfully logged into database.GGSCI (GOLDENGATE1) 5> add checkpointtable goldengate.chkpointSuccessfully created checkpoint table goldengate.chkpoint.

11. 增加EXTRACT
 

add extract w2ext, tranlog, begin now

修改配置：

GGSCI (GOLDENGATE2) 4> edit params w2extEXTRACT w2extUSERID goldengate, PASSWORD goldengateTRANLOGOPTIONS EXCLUDEUSER goldengateIGNOREREPLICATESEXTTRAIL /home/oracle/gg/trails/w2DISCARDFILE w1extdsc,APPEND,MEGABYTES 5TRANLOGOPTIONS ALTARCHIVELOGDEST /home/oracle/archivelogTRANLOGOPTIONS ALTARCHIVEDLOGFORMAT %t_%s_%r.dbfDDL INCLUDE MAPPEDDDLOPTIONS ADDTRANDATAFETCHOPTIONS, USESNAPSHOT, NOUSELATESTVERSION, MISSINGROW REPORTSTATOPTIONS REPORTFETCHWARNLONGTRANS 1H, CHECKINTERVAL 5MTABLE hr.*;

 

添加该extract对应的trail文件，用来存储抽取的数据。单个文件大小设置为100MB

GGSCI (GOLDENGATE2) 5> add exttrail /home/oracle/gg/trails/w2,extract w2ext, megabytes 100EXTTRAIL added.

12. 修改原源库EXTRAIL参数，增加以下两行：

TRANLOGOPTIONS EXCLUDEUSER goldengateIGNOREREPLICATES

13. 增加PUMP

add extract w2extdp, exttrailsource /home/oracle/gg/trails/w2, begin now

修改配置：

GGSCI (GOLDENGATE2) 7> edit params w2extdpEXTRACT w2extdpUSERID goldengate, PASSWORD goldengateRMTHOST 192.168.102.156, MGRPORT 5898RMTTRAIL /home/oracle/gg/trails/w2DISCARDFILE w1extdpdsc,APPEND,MEGABYTES 5TABLE hr.*;

 

14. 添加远程TRAIL文件：

修改配置参数：

GGSCI (GOLDENGATE1) 12> edit params w2repREPLICAT w2repASSUMETARGETDEFSUSERID goldengate, PASSWORD goldengateDISCARDFILE w2repdsc,APPEND,MEGABYTES 5DDL INCLUDE MAPPEDDDLOPTIONS REPORTBATCHSQLDBOPTIONS DEFERREFCONSTDBOPTIONS LOBWRITESIZE 102400DDLERROR DEFAULT DISCARD RETRYOP MAXRETRIES 5 RETRYDELAY 20MAP hr.* , TARGET hr.* ;

16. 在源端增加传输表。

GGSCI (GOLDENGATE2) 12> dblogin userid goldengate, password goldengateSuccessfully logged into database.GGSCI (GOLDENGATE2) 13> add trandata hr.*Logging of supplemental redo data enabled for table HR.COUNTRIES.Logging of supplemental redo data enabled for table HR.DEPARTMENTS.Logging of supplemental redo data enabled for table HR.EMPLOYEES.Logging of supplemental redo data enabled for table HR.JOBS.Logging of supplemental redo data enabled for table HR.JOB_HISTORY.Logging of supplemental redo data enabled for table HR.LOCATIONS.Logging of supplemental redo data enabled for table HR.REGIONS.2012-09-21 02:55:40  WARNING OGG-00869  No unique key is defined for table 'T'.

17. 查源库SCN。

SQL> select current_scn from v$database;CURRENT_SCN-----------     525516

18. 启动GG各进程。
注意启动REP进程时：

GGSCI (GOLDENGATE1) 19> start w2rep, aftercsn 525516Sending START request to MANAGER ...REPLICAT W2REP startingGGSCI (GOLDENGATE1) 20> info allProgram     Status      Group       Lag at Chkpt  Time Since ChkptMANAGER     RUNNING                                           EXTRACT     RUNNING     W1EXT       00:00:00      00:00:08    EXTRACT     RUNNING     W1EXTDP     00:00:00      00:00:01    REPLICAT    RUNNING     W2REP       00:00:00      00:00:00   

19， 测试。
