Hi,
do you mean database lock in the DB so server complains that database is locked by another instance? If yes, you should list peer IP address in netxmsd.conf on cluster nodes. For example, if you have cluster nodes with addresses 10.0.0.1 and 10.0.0.2 (with whatever VIP moving between them), on node 10.0.0.1 you should add
PeerNode = 10.0.0.2
to netxmsd.conf and on node 10.0.0.2 add
PeerNode = 10.0.0.1
That way server will read the lock, check if server is running on peer node (by attempting to connect to agent and check running processes and by connecting to port 4701), and remove stalled lock if netxmsd is not running on peer node.
Best regards,
Victor
