1.1Configure Oracle Database for
Goldengate
1.1.1Create Goldengate user
Create user ogg for both source system and
target system, and grant appropriate privileges.
为源库和目标库创建ogg用户并赋予相应权限。
1.1.1.1For Source System(PROD):
创建表空间；创建用户、赋予权限
[oracle@rhel101 ~]$ sqlplus / as sysdba
SYS@PROD>create tablespace tbs_gguser datafile
'/u01/app/oracle/oradata/PROD/gguser.dbf' size 50m
autoextend on;
SYS@PROD>create user ogg identified by ogg default
tablespace tbs_gguser
2 temporary tablespace TEMP quota unlimited on
tbs_gguser;
SYS@PROD>grant connect,resource to ogg;
SYS@PROD>grant alter session to ogg;
SYS@PROD>grant select any table,select any dictionary,alter any table to ogg;
SYS@PROD>grant
flashback any table to ogg;
SYS@PROD>grant
execute on dbms_flashback to ogg;
Create test table for Source System:
为源库创建测试表、插入数据、创建主键约束
SYS@PROD>conn scott/tiger
SCOTT@PROD>create table ggtab as select * from emp;
SCOTT@PROD>alter table ggtab add constraint
pk_ggtab_empno primary key(empno);
SCOTT@PROD>select * from ggtab;
1.1.1.2 For Target System(EMREP):
创建表空间；创建用户、赋予权限
[oracle@rhel102 ~]$ sqlplus / as sysdba
SYS@EMREP>create tablespace tbs_gguser datafile
2 '/u01/app/oracle/oradata/EMREP/gguser.dbf'
size 50m autoextend on;
SYS@EMREP>create user ogg identified by ogg default
tablespace tbs_gguser
2 temporary tablespace TEMP quota unlimited on
tbs_gguser;
SYS@EMREP>grant connect,resource to ogg;
SYS@EMREP>grant alter session to ogg;
SYS@EMREP>grant select any dictionary, select any table
to ogg;
SYS@EMREP>grant
update any table,delete any table,insert any table to ogg;
Create empty test table
SYS@EMREP>conn scott/tiger
SCOTT@EMREP>create table ggtab as select * from emp where
1=2;
SCOTT@EMREP>alter table ggtab add constraint pk_ggtab_empno
primary key(empno);
1.1.2Enable supplemental log mode in source system
Check that supplemental log mode is enabled
by following query:
SYS@PROD>select supplemental_log_data_min from
v$database;
SUPPLEME
--------
NO
If not, enable it:
SYS@PROD>alter database add supplemental log data;
SYS@PROD>alter system switch logfile;
SYS@PROD>select supplemental_log_data_min from
v$database;
1.1.3Enable archive log mode in source system
Enable archive log mode:
[oracle@rhel101 ~]$ mkdir /u01/app/oracle/arch
[oracle@rhel101 ~]$ls -ld /u01/app/oracle/arch
SYS@PROD>alter system set
log_archive_dest_1='location=/u01/app/oracle/arch';
SYS@PROD>shutdown immediate;
SYS@PROD>startup mount;
SYS@PROD>alter database archivelog;
SYS@PROD>alter database open;
SYS@PROD>alter system archive log current;
SYS@PROD>archive log list;
1.1.4Enable force logging mode in source system
Enable force logging mode: in case of "no
logging" operations
SYS@PROD>alter database
force logging;
SYS@PROD>select force_logging
from v$database;
1.1.5Enable transaction data change capture for test table in Source
system
GGSCI (rhel101.oracle.com) 11> dblogin userid
ogg,password ogg
Successfully logged into database.
GGSCI (rhel101.oracle.com) 12> add trandata scott.ggtab
Logging of supplemental redo data enabled
for table SCOTT.GGTAB.
GGSCI (rhel101.oracle.com) 13> info trandata
scott.ggtab
Logging of supplemental redo log data is
enabled for table SCOTT.GGTAB.
Columns supplementally logged for table
SCOTT.GGTAB: EMPNO.
1.2Configure Goldengate Manager
Process
1.2.1Configure MGR in source system
Create the Manager parameter file.
[oracle@rhel101 11.2.1]$ ggsci
GGSCI (rhel101.oracle.com) 1> edit params mgr
Use the editor to assign a port.此端口号对应 对端的pump配置端口号

is running (IP port rhel101.oracle.com.7809).
1.2.2Configure MGR in target system
Create the Manager parameter file.
GGSCI (rhel102.oracle.com) 5> edit params mgr
PORT 7809
PURGEOLDEXTRACTS /u01/app/oracle/ggs/11.2.1/dirdat,
