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.
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
- 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 UNIX
Configure database client environment variables on the machines that run the Data Integration Service, PowerCenter Integration Service, and PowerCenter Repository Service processes.
The database client path variable name and requirements depend on the UNIX platform and the database.
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 in UNIX:
Database | Environment Variable Name | Database Utility | Value |
|---|
Oracle | ORACLE_HOME PATH | sqlplus | Set to: <DatabasePath> Add: <DatabasePath>/bin |
IBM DB2 | DB2DIR DB2INSTANCE PATH | db2connect | Set to: <DatabasePath> Set to: <DB2InstanceName> Add: <DatabasePath>/bin |
Sybase ASE | SYBASE15 SYBASE_ASE SYBASE_OCS PATH | isql | Set to: <DatabasePath>/sybase<version> Set to: ${SYBASE15}/ASE-<version> Set to: ${SYBASE15}/OCS-<version> Add: ${SYBASE_ASE}/bin:${SYBASE_OCS}/bin:$PATH |
