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. For more information about configuring connectivity, see Connecting to Databases.
The Data Integration Service uses native connectivity to connect to different databases:
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.

Install Database Client Software

You must install the database clients on the required machines based on the types of databases that the application services access.
To ensure compatibility between the application service and the database, use the appropriate database client libraries and install a client software that is compatible with the database version.
Install the following database client software based on the type of database that the application service accesses:
IBM DB2 Client Application Enabler (CAE)
Configure connectivity on the required machines by logging in to the machine as the user who starts Informatica services.
Microsoft SQL Server 2012 Native Client
You must install the Microsoft SQL Server 2012 Native Client for the existing mappings to work.
Download the client from the following Microsoft website: http://www.microsoft.com/en-in/download/details.aspx?id=29065.
Oracle client
Install compatible versions of the Oracle client and Oracle database server. You must also install the same version of the Oracle client on all machines that require it. To verify compatibility, contact Oracle.
Sybase Open Client (OCS)
Install an Open Client version that is compatible with the Sybase ASE database server. You must also install the same version of Open Client on the machines hosting the Sybase ASE database and Informatica. To verify compatibility, contact Sybase.

Configure Database Client Environment Variables on Linux

Configure database client environment variables on the machines that run the Data Integration Service processes.
After you configure the database environment variables, you can test the connection to the database from the database client.
The following table lists the database environment variables you need to set:
Database
