PostgreSQL Database Requirements

PostgreSQL Database Requirements

Utilisez les instructions suivantes lors de la configuration du référentiel sous PostgreSQL :
  • Vérifiez que le compte utilisateur de la base de données dispose des privilèges CREATE TABLE et CREATE VIEW.
  • Assurez-vous que l'espace disque de PostgreSQL est suffisant pour les fichiers de données. Par défaut, ceux-ci se trouvent à l'emplacement suivant :
    <PostgreSQL installation directory>/data
  • Dans la base de données, définissez les paramètres de configuration.
    Le tableau suivant répertorie les valeurs minimale et recommandée des paramètres de configuration que vous devez définir :
    Paramètre
    Valeur minimale
    Valeur recommandée
    max_connections
    200
    4000
    shared_buffers
    2 Go
    16 Go
    max_locks_per_transaction
    1024
    4000
    max_wal_size
    1 Go
    8 Go
    checkpoint_timeout
    5 minutes
    30 minutes
  • To configure 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 Service database service name
    Ensure that the entries for the [PCRS_DB_SERVICE_NAME] entry matches the information for the PowerCenter Repository Service. To securely connect to PostgreSQL for the PowerCenter repository, set the security property along with the remaining required database properties in the pg_service.conf file in the following format:
    sslmode=require
  • Set the PGSERVICEFILE environment variable to the location of the pg_service.conf file. The pg_service.conf file contains the connection parameters for PostgreSQL database connection in the Informatica installation directory. 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
