NAME

       STORE LISTEN - Configure Slony-I node to indicate where to listen for events

SYNOPSIS

       STORE LISTEN (options);

DESCRIPTION

       A  ‘listen’  entry  causes  a  node  (receiver) to query an event provider for events that
       originate from a specific node, as well as confirmations  from  every  existing  node.  It
       requires  a  ‘path’  to exist so that the receiver (as client) can connect to the provider
       (as server).

       Every node in the system must listen for events from every other node in the system. As  a
       general rule of thumb, a subscriber (see SLONIK SUBSCRIBE SET(7)) should listen for events
       of the set's origin on the same provider, where it receives the data from.  In  turn,  the
       origin of the data set should listen for events from the origin in the opposite direction.
       A node can listen for events from one and the same origin on different  providers  at  the
       same  time. However, to process SYNC events from that origin, all data providers must have
       the same or higher sync status,  so  this  will  not  result  in  any  faster  replication
       behaviour.

       ORIGIN = ival
              Node ID of the event origin the receiver is listening for.

       PROVIDER = ival
              Node  ID of the node from which the receiver gets events that come from the origin.
              If not specified, default is the origin.

       RECEIVER = ival
              The ID of the node receiving the events.

       This uses “schemadocstorelisten(p_receiver integer, p_provider integer, p_origin integer)”
       [not available as a man page].

       For more details, see “Slony-I Listen Paths” [not available as a man page].

EXAMPLE

            STORE LISTEN ( ORIGIN = 1, RECEIVER = 2, PROVIDER = 3 );

LOCKING BEHAVIOUR

       No application-visible locking should take place.

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.

VERSION INFORMATION

       This command was introduced in Slony-I 1.0. As of version 1.1, you should no  longer  need
       to use this command, as listen paths are generated automatically.
