Dear Readers,
In this article we will see Oracle to Oracle GoldenGate Unidirectional Replication.
Prerequisites for Replication:
1.Create two Vm/s on your machine
2.Install Oracle Software and Create databases.
3.Make sure two Vm’s are pining each other
Node Details :
GG1 (SOURCE)
192.168.0.51 gg1.orcl.com gg1
Database Name :PRIMARY
Instance Name : primary
GG2(TARGET)
192.168.0.61 gg2.orcl.com gg2
Database Name :PRIMARY
Instance Name : primary
(I have taken same names on both machines)
Download Goldengate Binaries
Download GoldenGate binaries from Oracle.com using below link
https://www.oracle.com/technetwork/middleware/goldengate/downloads/index.html
Make sure that you are using the correct OS version of binaries.
