2.获取语法帮助信息
(1).必须要ggsci根目录进入ggsci终端,否则获取不到帮助信息
(2).帮助语法: help
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
[, MEGABYTES
[SEQNO
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.
The name of the Extract group to which the trail is bound. Only one
Extract process can write data to a trail.
MEGABYTES
The maximum size, in megabytes, of a file in the trail. The default is
100.
SEQNO
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

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端创建表空间,用户和测试表(只有source端有测试数据)
source节点:
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节点:
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端启动mgr进程(两个节点都需要做)
aource节点:
GGSCI (oracle11g) 3> edit params mgr --设置mgr的端口
-- port --这个是注释
PORT 7809 --指定的端口
GGSCI (oracle11g) 4> start mgr --启动mgr
Manager started.
GGSCI (oracle11g) 6> info mgr --查看mgr的状态
Manager is running (IP port oracle11g.7809).
GGSCI (oracle11g) 7>
6.配置glodengate需要同步的表(source节点)
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.初使化数据(将source的数据导入到target节点中)
source节点:
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

GGSCI (oracle11g) 12>
target节点:
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.启动
source节点:
GGSCI (oracle11g) 12> start extract einiaa
Sending START request to MANAGER ...
EXTRACT EINIAA starting
GGSCI (oracle11g) 13> view report einiaa
