INIT CLUSTER - Initialize Slony-I cluster
INIT CLUSTER [ID = integer] [COMMENT = 'string']
Initialize the first node in a new Slony-I replication cluster. The
initialization process consists of creating the cluster namespace,
loading all the base tables, functions, procedures and initializing the
node, using “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].
ID The unique, numeric ID number of the node.
COMMENT = 'comment text'
A descriptive text added to the node entry in the table
“sl_node” [not available as a man page].
For this process to work, the SQL scripts of the Slony-I system must be
installed on the DBA workstation (the computer currently executing the
slonik utility), while on the system where the node database is running
the shared objects of the Slony-I system must be installed in the
PostgreSQL library directory. Also the procedural language PL/pgSQL is
assumed to already be installed in the target database.
INIT CLUSTER (
ID = 1,
COMMENT = 'Node 1'
This command functions very similarly to SLONIK STORE NODE(7),
the difference being that INIT CLUSTER does not need to draw
configuration from other existing nodes.
Be aware that some objects are created that contain the cluster
name as part of their name. (Notably, partial indexes on
sl_log_1 and sl_log_2.) As a result, really long cluster names
are a bad idea, as they can make object names ‘blow up’ past the
typical maximum name length of 63 characters.
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
