Using bidirectional replication with the File Channel endpoint

You can use bidirectional replication together with the File Channel endpoint. This is useful if you need to synchronize two endpoints that are either not able to communicate with each other (i.e. are not physically connected) or are located in the WAN. The process involves setting up six separate tasks: Two Full Load-only Unidirectional tasks and four Apply Changes-only Bidirectional tasks.

For information on setting up the File Channel endpoint, see Using the Qlik Replicate file channel.

To set up bidirectional replication with File Channel Endpoints:

1. Set up and run two Full Load only Unidirectional tasks.

   Example (FC = File Channel):

   Task 1: MySQL --> FC Target Task 2: FC Source --> Oracle

2. Wait for the Full Load-only tasks to finish.

3. Set up and run four Apply Changes-only Bidirectional tasks.

   Example (FC = File Channel):

   Task 1: MySQL Source --> FC Target Task 2: FC Source 1 --> Oracle Target

   Task 3: Oracle Source --> FC Target 2 Task 4: FC Source 2 --> MySQL Target
