SLONIK CLONE PREPARE(7)                      Configuration and Action commands

NAME
       CLONE PREPARE - Prepare for cloning a node.

SYNOPSIS
       clone prepare  [  id ] [  provider ] [  comment ]

DESCRIPTION
       Prepares for cloning a specified subscriber node.

       This duplicates the ``provider'' node's configuration under a new node
       ID in preparation for the node to be copied via standard database
       tools.

       Note that in order that we be certain that this new node be consistent
       with all nodes, it is important to issue a SYNC event against every
       node aside from the provider and wait to start copying the provider
       database at least until all those SYNC events have been confirmed by
       the provider.  Otherwise, it is possible for the clone to miss some
       events.

EXAMPLE
            clone prepare (id = 33, provider = 22, comment='Clone 33');
            sync (id=11);
            sync (id=22);

SLONIK EVENT CONFIRMATION BEHAVIOUR
       Slonik will wait until the node being cloned (the provider) is caught
       up with all other nodes before submitting the clone prepare command

VERSION INFORMATION
       This command was introduced in Slony-I 2.0.
