About installing the CDC Replication Engine for Db2 for i on the Source Server

The Source Server represents a System i machine where your remote journal objects and receivers reside. In addition to installing on the Data Origin Server, you must install CDC Replication as a source product on this system when setting up replication from a remote journal.

CDC Replication will run source replication jobs (SCRAPE, MIRROR and REFRESH). After installing CDC Replication on the Data Origin Server, you must install CDC Replication in the same product library on the Source Server.

It is important to note that although your source files reside on the Data Origin Server, Management Console connects to the Source Server and uses this as the source datastore within a subscription. Using system parameters, you must configure your installation of CDC Replication on the Source Server to retrieve data from actual source files which reside on the Data Origin Server. This is referred to as the CDC Replication Source Server to indicate that CDC Replication must be installed.

If the target files also reside on the same server (for example, the Source Server), then you will have to install another instance of CDC Replication on the same machine. In this scenario, you will have to install two instances of CDC Replication to run both source (SCRAPE, MIRROR and REFRESH) and target (APPLY) replication jobs.
