To ensure compatibility between the application service and the database, install the client software associated with relational source systems and the repository databases.

The following table describes where to install the client software and configure connectivity:

CDI-PC Integration Service Configuration	Where to configure
On a single node or on primary and back-up nodes	All machines that run the CDI-PC Integration Service
