Configure Native Connectivity on Service Machines

To establish native connectivity between an application service and a database, install the database client software for the database that you want to access.

Native drivers are packaged with the database server and client software. Configure connectivity on the machines that need to access the databases. To ensure compatibility between the application service and the database, install a client software that is compatible with the database version and use the appropriate database client libraries.

The following services use native connectivity to connect to different databases:

Data Integration Service: The Data Integration Service uses native database drivers to connect to the following databases:
Source and target databases. Reads data from source databases and writes data to target databases.
Data object cache database. Stores the data object cache.
Profiling source databases. Reads from relational source databases to run profiles against the sources.
Profiling warehouse. Writes the profiling results to the profiling warehouse.
Reference tables. Runs mappings to transfer data between the reference tables and the external data sources.; When the Data Integration Service runs on a single node or on primary and back-up nodes, install database client software and configure connectivity on the machines where the Data Integration Service runs.

When the Data Integration Service runs on a grid, install database client software and configure connectivity on each machine that represents a node with the compute role or a node with both the service and compute roles.
PowerCenter Repository Service: The PowerCenter Repository Service uses native database drivers to connect to the PowerCenter repository database.; Install database client software and configure connectivity on the machines where the PowerCenter Repository Service and the PowerCenter Repository Service processes run.

PowerCenter Integration Service: The PowerCenter Integration Service uses native database drivers to connect to the following databases:
Source and target databases. Reads from the source databases and writes to the target databases.
Metadata Manager source databases. Loads the relational data sources in Metadata Manager.; Install database client software associated with the relational data sources and the repository databases on the machines where the PowerCenter Integration Service runs.
