Red Hat Summit5.2. Using Referential Integrity with Replication
There are certain limitations when using the Referential Integrity Postoperation plug-in in a replication environment:
- Never enable it on a dedicated consumer server (a server that contains only read-only replicas).
- Never enable it on a server that contains a combination of read-write and read-only replicas.
- Enable it on a supplier server that contains only read-write replicas.
- Enable the plug-in for each supplier server in multi-supplier replication topology. The plug-in configuration must be the same on all supplier servers.
Note
Because the supplier server sends any changes made by the Referential Integrity Postoperation plug-in to consumer servers, it is unnecessary to run the Referential Integrity Postoperation plug-in on consumer and hub servers.
