SLONIK STORE PATH

Description

Configures how the replication daemon of one node connects to the database of another node. If the replication system is supposed to use a special backbone network segment, this is the place to user the special IP addresses or hostnames. An existing configuration can be overwritten.

The conninfo string must contain all information to connect to the database as the replication superuser. The names "server" or "client" have nothing to do with the particular role of a node within the cluster configuration. It should be simply viewed as "the server" has the message or data that "the client is supposed to get." For a simple 2 node setup, paths into both directions must be configured.

It does not do any harm to configure path information from every node to every other node (full cross product). The connections are not established unless they are required to actually transfer events or confirmations because of listen entries or data because of subscriptions.

This uses schemadocstorepath(p_pa_connretry integer, p_pa_conninfo integer, p_pa_client text, p_pa_server integer).

Example

STORE PATH ( SERVER = 1, CLIENT = 2, 
             CONNINFO = 'dbname=testdb host=server1 user=slony'
           );
    

Locking Behaviour

No application-visible locking should take place.
