slonik set move sequence(7)
NAME
SET MOVE SEQUENCE - Move a sequence from one Slony-I replication set to
another
SYNOPSIS
SET MOVE SEQUENCE (options);
DESCRIPTION
- Change the set a sequence belongs to. The current set and the new set
must originate on the same node and subscribed by the same nodes.
- Caution
- Due to the way subscribing to new sets works make absolutely sure that the subscription of all nodes to the sets is completely processed before moving sequences. Moving a sequence too early to a new set causes the subscriber to try and add the sequence already during the subscription process, which fails with a duplicate key error and breaks replication.
- ORIGIN = ival
- Origin node for the set. A future version of slonik might figure out this information by itself.
- ID = ival
- Unique ID of the sequence.
- NEW SET = ival
- Unique ID of the set to which the sequence should be moved.
- This uses "schemadocsetmovesequence( integer, integer )" [not available as a man page].
EXAMPLE
- SET MOVE SEQUENCE (
- ORIGIN = 1,
ID = 20,
NEW SET = 3 - );
LOCKING BEHAVIOUR
No application-visible locking should take place.
VERSION INFORMATION
- This command was introduced in Slony-I 1.0.5
