The document provides a detailed guide for setting up Oracle 12c Golden Gate on Oracle Linux virtual machines, including the creation and configuration of two virtual machines in VirtualBox. It outlines the prerequisites such as disabling firewalls, updating host files, installing necessary packages, and step-by-step installation instructions for Oracle 12c database and Golden Gate software on both virtual machines. Additionally, it describes setting environment variables, enabling supplemental logging for replication, and configuring the manager process to manage Golden Gate operations.

1. INSTALL ORACLE
12C GOLDEN GATE
ON ORACLE LINUX

2. Virtual Machine Setup
To proceed with golden gate lab practice, create two virtual
machines in VirtualBox as per below configurations:
Partitions created while installing OEL 6.5
Note: To learn how to install OEL 6.5, complete the free video course –

3. https://oraclegenesis.com/p/foundation-for-dba
Once your machines are ready, complete below pre-requisites on
both. Disable firewall on both machines:

5. Update /etc/hosts file on both server, update your IP address for
both machines at the end of the file. Do not delete the first two
lines in the file
Perform update for all yum repository on both server.
This command will take 20-30 min.

6. Install Oracle 12c pre-install package which will
complete all the pre-requisites for us on both servers
Change the password for Oracle user on both server

7. Create necessary directories for Oracle 12c software
installation on both servers

8. Install Oracle 12c
Database
Now we are going to install Oracle 12c R1 database
software on both the virtual machines.
Oracle Database Software: 12.1.0.2

9. Copy the 12c installation zip files on both the servers under
/u02.GGPROD:
GGDEV:

10. Install 12c on GGPROD and create proddb database: Use
below options to install Oracle 12c on GGPROD server:
Installation option: Install database software only
Single instance database installation
Enterprise Edition
Oracle Base: /u01/app/oracle
Software Location: /u01/app/oracle/product/12.1.0/dbhome_1
Inventory Directory: /u01/app/oraInventory
oraInventory Group Name: oinstall
Operating system groups: dba (set all to dba)
Proceed to install the database software

11. Set the environment variables, Start DBCA and create proddb
database with below options:
1. Database Option: Create Database
2. Creation Mode: Advanced Mode
3. Database Template: General Purpose
4. Database SID: proddb (Container Database – uncheck / disabled)
5. Management Options: All options unchecked

12. 6. Database Credentials: Provide sys user password
7. Listener Configuration: Uncheck (we will configure listener manually)
8. Storage Locations:
a. User common locations for all database files
b. Enable FRA with 20 GB size c. Enable archiving
9. Database Options: Check Sample Schemas

13. Install 12c on GGDEV and create devdb
database: User below option to install
Oracle 12c on GGDEV server:
1. Installation option: Install database software only
2. Single instance database installation
3. Enterprise Edition
4. Oracle Base: /u01/app/oracle
5. Software Location: /u01/app/oracle/product/12.1.0/dbhome_1

14. 6. Inventory Directory: /u01/app/oraInventory
7. OraInventory Group Name: oinstall
8. Operating system groups: dba (set all to dba)
9. Proceed to install the database software
Set the environment variables, Start DBCA and create devdb
database with below options:

15. Install Oracle 12c
Golden Gate
Our next step is to install Oracle 12c Golden Gate software on both the
virtual machines.
Oracle Golden Gate Software: 12.2.0.1
Copy the golden gate installation zip files on both the servers under /u02.

16. Install Golden Gate on GGPROD
Unzip the golden gate zip file
Start installing Golden Gate on GGPROD server

18. Do not start the manager process as we will start it later:

22. Add GG_HOME variable to .bash_profile
export GG_HOME=/u01/app/oracle/product/gg

23. Execute the bash profile OR logout and login again as oracle user
Create Golden Gate sub directories: Connect to ggsci utility and
create golden gate sub directories

24. Output:

25. Install Golden Gate on GGDEV
Unzip the golden gate zip file
Start installing Golden Gate on GGPROD server

27. Do not start the manager process as we will start it later:

31. Add GG_HOME variable to .bash_profile
export GG_HOME=/u01/app/oracle/product/gg

32. Execute the bash profile OR logout and login again as oracle user
Create Golden Gate sub directories: Connect to ggsci utility
and create golden gate sub directories

33. Output:

34. Prepare Golden Gate for Replication
Enable supplemental logging: The amount of data written to redo logs
by default is not enough for replication. By enabling supplemental
logging, database will write more details about transactions in redo
log files.

35. Enable Golden Gate Replication Parameter: From 12.1.0.2 onwards,
there is a new parameter which we need to enable in order to setup
replication.
Create GoldenGate Database User: We need to create a dedicated
golden gate user on both source and target databases. The golden
gate user on source reads the transactions and the golden gate user
on target applies the transactions.

36. We will create new user with dedicated tablespace in
both databases.

37. Grant admin privileges to ogg user:
Create sbdirs
Configure and start manager process: While installing golden
gate, we did not start the manager process. Let us configure the
manager and start it on the source and target.

38. Add the below port number to the file

39. start the manager process
To view the status of mgr process

40. Repeat same steps to configure manager process on devdb and start
it
