SHUTDOWN

Shuts down a Vertica database.

Shuts down a Vertica database. By default, the shutdown fails if any users are connected. You can check the status of the shutdown operation in the vertica.log file.

Tip

Before calling SHUTDOWN, you can close all current user connections and prevent further connection attempts as follows:

Temporarily set configuration parameter MaxClientSessions to 0.
Call CLOSE_ALL_SESSIONS to close all non-dbamin connections.

This is a meta-function. You must call meta-functions in a top-level SELECT statement.
