Name

sys_lockdown — Set virtuoso in lockdown state and back.

Synopsis

sys_lockdown ( in lock_action integer ,
in listeners_mode integer );

Description

You must have DBA privileges to run that function.

Calling this with lock_mode = 1 causes the server not to accept any new client connections, except ones coming from localhost (127.0.0.1). This will also shut down any other listeners and terminate any possibly pending processing, rolling back all open transactions and disconnecting all clients, except ones from localhost. Calling thi with lock_mode 0 reverses the effect.

Parameters

lock_action

(0|1) - 0 = unlock the server; 1 = lock the server

listeners

(0|1 default 0) - 0 = don't serve the listener sockets; 1 = close the listener sockets

Return Types

Lock mode (lock_action = 1) if already in that mode returns 0 otherwise returns 1

Unlock mode (lock_action = 0) if already in that mode returns 0 otherwise returns 2
