oracle Golden Gate configuration

--Source and target database

1) Check oracle database LOG_MODE is set to ARCHIVELOG.

[oracle@gg1 admin]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.2.0 Production on Wed Apr 22 07:34:36 2015

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> SELECT log_mode FROM v$database;

LOG_MODE
------------
ARCHIVELOG

SQL>

---The result should be ARCHIVELOG. If it is, then skip to the next step.
If the result is NOARCHIVELOG, then do the following:

SQL> SELECT log_mode FROM v$database;

LOG_MODE
------------
NOARCHIVELOG

SQL> shutdown immediate
SQL> startup mount

SQL>ALTER DATABASE ARCHIVELOG;

SQL> ALTER DATABASE OPEN;

SQL> SELECT log_mode FROM v$database;

LOG_MODE
------------
ARCHIVELOG

SQL>

SQL> SELECT force_logging, supplemental_log_data_min FROM v$database;

FOR SUPPLEME
--- --------
YES YES

----The results should both be YES. If it is, then skip to the next step.
If either result is NO, then do the following:

SQL> SELECT force_logging, supplemental_log_data_min FROM v$database;

FOR SUPPLEME
--- --------
NO NO

SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
Database altered.

SQL> ALTER DATABASE FORCE LOGGING;
Database altered.

SQL> ALTER SYSTEM SWITCH LOGFILE;
System altered.

SQL> SELECT force_logging, supplemental_log_data_min FROM v$database;

FOR SUPPLEME
--- --------
YES YES


SQL>CREATE USER ggate IDENTIFIED BY ggate;

SQL> GRANT dba TO ggate;

2) For DLL replication we need to run below sql scripts.

----Run all sql scripts by sys user

SQL> @/u01/app/oracle/product/gg/marker_setup.sql
SQL> @/u01/app/oracle/product/gg/ddl_setup.sql
SQL> @/u01/app/oracle/product/gg/role_setup.sql
SQL> grant GGS_GGSUSER_ROLE to ggate;
SQL> @/u01/app/oracle/product/gg/ddl_enable.sql

3) Create check point table on both source and target.

On source

[oracle@gg1 gg]$ vi GLOBALS

CheckpointTable oggadm1.oggchkpt

on target

[oracle@gg2 gg]$ vi GLOBALS

CheckpointTable oggadm1.oggchkpt


4) Create manager process on both source and target.

On source

[oracle@gg1 gg]$ ./ggsci

11) Check DLL replication.

- Source side

SQL> conn scott/tiger
Connected.

SQL> create table t1 (id number);

Table created.

--target side

SQL> conn scott/tiger
Connected.

SQL> select count(*) from t1;

  COUNT(*)
----------
         0

12) Data replication

---On source side..

SQL> insert into t1 values(12);

1 row created.

SQL> commit;

Commit complete.

SQL> select count(*) from t1;

  COUNT(*)
----------
         1

SQL>
