oracle 11g goldengate与oracle 11g数据同步
1.下載,安裝goldengate軟件(兩個節都需要安裝)
glodengate下載地址：http://pan.baidu.com/s/1pLtVTJt 密碼：exob
[oracle@oracleogg ~]$ unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
[oracle@oracleogg ~]$ tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar -C /u01/glodengate/
[oracle@oracleogg ~]$ cd /u01/glodengate/

export ORACLE_SID=oracle11g

2.獲取語法幫助信息
(1).必須要ggsci根目錄進入ggsci終端,否則獲取不到幫助信息
(2).幫助語法: help <command> <object> ? 比如:help add rmttrail
GGSCI (oracleogg) 3> help add rmttrail
ADD RMTTRAIL?
Use ADD RMTTRAIL to create a trail for online processing on a remote?
system and:?
* assign a maximum file size.?
* associate the trail with an Extract group.?
In the parameter file, specify a RMTHOST entry before any RMTTRAIL?
entries to identify the remote system and TCP/IP port for the Manager?
process.?
Syntax:?
?
ADD RMTTRAIL <trail name>, EXTRACT <group name> ?
[, MEGABYTES <n>]?
[SEQNO <n>]?
?
<trail name>?
The fully qualified path name of the trail. The actual trail name can?
contain only two characters. Oracle GoldenGate appends this name with a?
six-digit sequence number whenever a new file is created. For example,?
a trail named ./dirdat/tr would have files named?
./dirdat/tr000001, ./dirdat/tr000002, and so forth. ?
?
<group name>?
The name of the Extract group to which the trail is bound. Only one?
Extract process can write data to a trail.?
?
MEGABYTES <n>?
The maximum size, in megabytes, of a file in the trail. The default is?
100. ?
?
SEQNO <n>?
Specifies that the first file in the trail will start with the?
specified trail sequence number. Do not include any zero padding. For?
example, to start at sequence 3 of a trail named "tr," specify SEQNO 3.?
The actual file would be named /ggs/dirdat/tr000003. This option can be?
used during troubleshooting when Replicat needs to be repositioned to a?
certain trail sequence number. It eliminates the need to alter Replicat?
to read the required sequence number.?
?
Example:?
ADD RMTTRAIL c:\ggs\dirdat\aa, EXTRACT finance, MEGABYTES 200?

3.在source端修改支持supplemental log日志
[oracle@oracle11g ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.1.0 Production on Sun Nov 20 04:18:26 2016
Copyright (c) 1982, 2009, Oracle. ?All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> alter database add supplemental log data; ? ? ??
Database altered.
SQL> alter system switch logfile;
System altered.
SQL> select supplemental_log_data_min from v$database;
SUPPLEME
--------
YES
SQL>?
4.在source端和target端創建表空間,用戶和測試表(只有source端有測試數據)
source節點:
SQL> create tablespace wuhan datafile '/u01/oracle/oradata/orac11g/wuhan.dbf' size 100m;
Tablespace created.
SQL> create user gguser identified by system default tablespace wuhan quota unlimited on wuhan;
User created.
SQL> grant dba,resource,connect to gguser;
Grant succeeded.
SQL> conn gguser/system
Connected.
SQL> create table t (a number,b char(10));
Table created.
SQL> insert into t values(1,'a');
1 row created.
SQL> insert into t values(2,'b');
1 row created.
SQL> insert into t values(3,'c');
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t;
? ?A ? ?B
---------- ----------
? ?1 ? ?a
? ?2 ? ?b
? ?3 ? ?c
SQL>?
target節點:
SQL> create tablespace wuhan datafile '/u01/app/oracle/oradata/oracleogg/wuhan.dbf' size 100m;
Tablespace created.
SQL> create user gguser identified by system default tablespace wuhan quota unlimited on wuhan;
User created.
SQL> grant dba,resource,connect to gguser;
Grant succeeded.
SQL> conn gguser/system
Connected.
SQL> create table t (a number,b char(10));
Table created.
SQL>?
5.source端和target端啟動mgr進程(兩個節點都需要做)
aource節點:
GGSCI (oracle11g) 3> edit params mgr ? ? ? ?--設置mgr的端口
-- port ? ? ? ? ? ? ? ? ?--這個是注釋
PORT 7809 ? ? ? ?--指定的端口
GGSCI (oracle11g) 4> start mgr ? ? ?--啟動mgr
Manager started.
GGSCI (oracle11g) 6> info mgr ? ? ?--查看mgr的狀態
Manager is running (IP port oracle11g.7809).
GGSCI (oracle11g) 7>?
6.配置glodengate需要同步的表(source節點)
GGSCI (oracle11g) 7> dblogin userid gguser, password system
Successfully logged into database.
GGSCI (oracle11g) 8> add trandata gguser.t ? ? ? ? ? ?--也可以使用通配符(add trandata gguser.*)
2016-11-20 05:32:50 ?WARNING OGG-00869 ?No unique key is defined for table 'T'. All viable columns will be used to represent the key, but may not guarantee uniqueness. ?KEYCOLS may be used to define the key.
Logging of supplemental redo data enabled for table GGUSER.T.
GGSCI (oracle11g) 9> info trandata gguser.*
Logging of supplemental redo log data is enabled for table GGUSER.T.
Columns supplementally logged for table GGUSER.T: A, B.
GGSCI (oracle11g) 10>?
7.初使化數據(將source的數據導入到target節點中)
source節點:
GGSCI (oracle11g) 10> add extract einiaa, sourceistable
EXTRACT added.
GGSCI (oracle11g) 11> edit params einiaa
EXTRACT EINIAA
USERID GGUSER, PASSWORD "system"
RMTHOST 192.168.3.90, MGRPORT 7809
RMTTASK REPLICAT, GROUP RINIAA
TABLE gguser.t;
GGSCI (oracle11g) 12>
target節點:
GGSCI (oracleogg) 10> add replicat riniaa, specialrun
REPLICAT added.
GGSCI (oracleogg) 11> edit params riniaa
REPLICAT RINIAA
ASSUMETARGETDEFS
USERID gguser, PASSWORD "system"
DISCARDFILE ./dirrpt/RINIAA.dsc, PURGE
MAP gguser.*, TARGET gguser.*;
GGSCI (oracleogg) 12>
8.啟動
source節點:
GGSCI (oracle11g) 12> start extract einiaa
Sending START request to MANAGER ...
EXTRACT EINIAA starting
GGSCI (oracle11g) 13> view report einiaa
2016-11-20 05:56:55 ?INFO ? ?OGG-01017 ?Wildcard resolution set to IMMEDIATE because SOURCEISTABLE is used.
