Whether or Not to Use DataPump with Oracle GoldenGate

edited Mar 17, 2020 5:02AM in GoldenGate, Streams and Distributed Database (MOSC) 4 commentsAnswered

We are setting up GoldenGate to keep 3 of our Oracle databases in sync. Regarding configuration: 

We plan to have an instance of GoldenGate running on all 3 nodes. Each node will run an extract on (local) Transaction/Redo Logs to create local Trail files, then run Replicat (locally) to the other 2 databases.

         

These connections are using TCP/IP so there should not be any lost packets? If Replicat running over the network sends and fails, will GG reattempt until it does or just move on? (Resulting in out of sync?)

DataPump/ Checkpoint process seems to be industry standard for replication over the network remedying the above process.

Howdy, Stranger!
