Name

DROP NODE — Remove the node from participating in the replication

Synopsis

DROP NODE (options);

Description

Drop a node. This command removes the specified node entirely from the replication systems configuration. If the replication daemon is still running on that node (and processing events), it will attempt to uninstall the replication system and terminate itself.

ID = ival

Node ID of the node to remove.

EVENT NODE = ival

Node ID of the node to generate the event.

This uses schemadocdropnode( integer ).

When you invoke DROP NODE, one of the steps is to run UNINSTALL NODE.

Warning

If you are using connections that cache query plans (this is particularly common for Java application frameworks with connection pools), the connections may cache query plans that include the pre-DROP NODE state of things, and you will get error messages indicating missing OIDs.

After dropping a node, you may also need to recycle connections in your application.

Example

     DROP NODE ( ID = 2 );
    

Locking Behaviour

When dropping triggers off of application tables, this will require exclusive access to each replicated table on the node being discarded.
