Configure Native Connectivity on Service Machines

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.

• •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.

Step 5. Install Database Client SoftwareInstall Database Client Software

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 2014 Native Client

You must install the Microsoft SQL Server 2014 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=42295.

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.

PostgreSQL client (psql)

Install and run the PostgreSQL interactive terminal program called psql, which allows you to interactively enter, edit, and run SQL commands.

psql is a terminal-based front-end to PostgreSQL. You can type in queries interactively, issue the queries to PostgreSQL, and check the query results. Or, the input can be from a file or from command line arguments.

You can install psql client application for PostgreSQL to work only on Linux or Windows.

Install and run the required software dependency packages to build PostgreSQL, such as GCC compiler package, readline and readline-devel packages, and zlib-devel compression library package. After you install the packages from the GNU Readline library, psql remembers each command you type, and you can use arrow keys to recall and edit previous commands.

You can also run the required library files with the yum install commands.

PostgreSQL on Windows

On Windows, download the psql client from the following link:

https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

You must verify that PostgreSQL libraries are present in the following directories on Windows:

• ▪ Installation directory: C:\Program Files\PostgreSQL\10
• ▪ Command line tools installation directory: C:\Program Files\PostgreSQL\10
• ▪ pgAdmin4 installation directory: C:\Program Files\PostgreSQL\10\pgAdmin 4

PostgreSQL on Linux

On Linux, you also need to install the required postgreSQL libraries, postgresql10-10.10-1PGDG.rhel7.x86_64 and postgresql10-libs-10.10-1PGDG.rhel7.x86_64

For more information about psql, see the psql client documentation in the following link: https://www.postgresql.org/docs/10/app-psql.html
