PostgreSQL Database Requirements

PostgreSQL Database Requirements

Siga estas directrices cuando configure el repositorio en PostgreSQL:
  • Confirme que la cuenta de usuario de la base de datos tiene los privilegios CREATE TABLE y CREATE VIEW.
  • Asegúrese de que PostgreSQL tiene espacio en disco suficiente para dar cabida a los archivos de datos. Los archivos de datos se encuentran en la siguiente ubicación de forma predeterminada:
    <directorio de instalación de PostgreSQL>/data
  • En la base de datos, establezca los parámetros de configuración.
    En la siguiente tabla se enumeran los valores mínimos y recomendados de los parámetros de configuración que deben establecerse:
    Parámetro
    Valor mínimo
    Valor recomendado
    max_connections
    200
    4000
    shared_buffers
    2 GB
    16 GB
    max_locks_per_transaction
    1024
    4000
    max_wal_size
    1 GB
    8 GB
    checkpoint_timeout
    5 minutos
    30 minutos
  • 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
