STORE NODE - Initialize Slony-I node
STORE NODE (options);
Initialize a new node and add it to the configuration of an existing
The initialization process consists of creating the cluster namespace
in the new node (the database itself must already exist), loading all
the base tables, functions, procedures and initializing the node. The
existing configuration of the rest of the cluster is copied from the
ID = ival
The unique, immutable numeric ID number of the new node.
Note that the ID is immutable because it is used as the basis
for inter-node event communications.
COMMENT = 'description'
A descriptive text added to the node entry in the table
“sl_node” [not available as a man page]
SPOOLNODE = boolean
Specifies that the new node is a virtual spool node for file
archiving of replication log. If true, slonik will not attempt
to initialize a database with the replication schema.
Never use the SPOOLNODE value - no released version of Slony-I
has ever behaved in the fashion described in the preceding
fashion. Log shipping, as it finally emerged in 1.2.11, does not
require initializing ‘spool nodes’.
EVENT NODE = ival
The ID of the node used to create the configuration event that
tells all existing nodes about the new node. It must be the ID
of a pre-existing node in the cluster, not the ID of the new
This uses “schemadocinitializelocalnode(p_comment integer,
p_local_node_id text)” [not available as a man page] and
“schemadocenablenode(p_no_id integer)” [not available as a man page].
STORE NODE ( ID = 2, COMMENT = 'Node 2', EVENT NODE = 1 );
This command creates a new namespace and configures tables therein; no
public objects should be locked during the duration of this.
SLONIK EVENT CONFIRMATION BEHAVIOUR
Slonik waits for the command submitted to the previous event node to be
confirmed on the specified event node before submitting this command.
This command was introduced in Slony-I 1.0. The SPOOLNODE parameter was
introduced in version 1.1, but was vestigial in that version. The
described functionality for SPOOLNODE arrived in version 1.2, but
SPOOLNODE was not used for this purpose. In later versions, hopefully
SPOOLNODE will be unavailable.
In version 2.0, the default value for EVENT NODE was removed, so a node
must be specified.
