# SLONIK ADMIN CONNINFO

## Name

ADMIN CONNINFO -- preamble - identifying PostgreSQL database

## Synopsis

`NODE ival ADMIN CONNINFO = 'DSN';` [`ival;`] [`'conninfo'`]

## Description

Describes how the slonik utility can reach a node's database in the cluster from where it is run (likely the DBA's workstation). The conninfo string is the string agrument given to the `PQconnectdb()` libpq function.

The slonik utility will not try to connect to a given database unless some subsequent command requires the connection.

> Note: As mentioned in the original documents, Slony-I is designed as an enterprise replication system for data centers. It has been assumed throughout the entire development that the database servers and administrative workstations involved in replication and/or setup and configuration activities can use simple authentication schemes like "trust". Alternatively, libpq can read passwords from `.pgpass` .

> Note: If you need to change the DSN information for a node, as would happen if the IP address for a host were to change, you must submit the new information using the SLONIK STORE PATH command, and that configuration will be propagated. Existing slon processes may need to be restarted in order to become aware of the configuration change.

## Example

         NODE 1 ADMIN CONNINFO = 'dbname=testdb host=server1 user=slony';

## Version Information

This command was introduced in Slony-I 1.0
