Configuring Native Connectivity

You can configure native connectivity to a PostgreSQL database to increase performance.

The following steps provide a guideline for configuring native connectivity through PostgreSQL. For specific instructions, see the database documentation.

To configure connectivity for the PowerCenter Integration Service and PowerCenter Repository Service process, log in to the machine as a user who can start the server process.

To configure a PostgreSQL database for the PowerCenter repository, set values for the PostgreSQL database host, port, and service name for the pg_service.conf file in the following format:

[PCRS_DB_SERVICE_NAME]
host=Database host IP
port=Database port
dbname=PowerCenter repository database service name

Ensure that the entries for the [PCRS_DB_SERVICE_NAME] match the configuration for the PowerCenter Repository Service. In the pg_service.conf file, you can securely connect to PostgreSQL for the PowerCenter repository. To set the secure connect, set the security property and the required database properties in the pg_service.conf file in the following format:

sslmode=require

Set the PGSERVICEFILE, PGHOME, and PATH environment variables.

PGSERVICEFILE
. Set the variable to the pg_service.conf file that contains the connection parameters for PostgreSQL database connection. For example, set the variable as follows:

Using a Bourne shell:

$ export PGSERVICEFILE; PGSERVICEFILE=<pg_service.conf file 
directory>/pg_service.conf

Using a C shell:

$ setenv PGSERVICEFILE <pg_service.conf file 
directory>/pg_service.conf

PGHOME
. Set the variable to the PostgreSQL installation path where you have installed the PostgreSQL client. For example, set the variable as follows:

Using a Bourne shell:

$ export PGHOME; PGHOME=/usr/pgsql-10

Using a C shell:

$ setenv PGHOME /usr/pgsql-10

PATH
. To run the PostgreSQL command line programs, set the variable to include the PostgreSQL client directory, psql. For example, set the variable as follows:

Using a Bourne shell:

$ export PATH; PATH=${PATH}:${PGHOME}

Using a C shell:

$ setenv PATH ${PGHOME}:${PATH}

Set the shared library environment variable.

The PostgreSQL client software contains a number of shared library components that the PowerCenter Integration Service and PowerCenter Repository Service processes load dynamically. To locate the shared libraries during run time, set the shared library environment variable.

The shared library path must also include the Informatica installation directory

(server_dir)

Set the shared library environment variable to LD_LIBRARY_PATH.

For example, use the following syntax:

Using a Bourne shell:

$ export LD_LIBRARY_PATH; LD_LIBRARY_PATH $PGHOME/lib
$ LD_LIBRARY_PATH <InstallationDirectory>/server/bin:${LD_LIBRARY_PATH}

Using a C shell:

$ setenv LD_LIBRARY_PATH $PGHOME/lib
$ setenv LD_LIBRARY_PATH <InstallationDirectory>/server/bin:${LD_LIBRARY_PATH}

Verify that you can connect to the PostgreSQL database.

To connect to the PostgreSQL database, launch the psql utility and enter the connectivity information.
