The best way to create connection to OrientDB

Question

I create a connection to the database is as follows:

ODatabaseDocumentTx db = new ODatabaseDocumentTx("remote:host1/test")
    .open("admin", "admin");

I have 2 nodes of DB. When I shutdown node, which was in constructor, then throws exception:

Database 'plocal:/root/orientdb/databases/test' is closed

Of course, I can catch this exception and create new connection to another server, but I think, this is wrong.

Is there way to create connection to full DB, not to single node of cluster?

Answer 1

If you run 2 servers in cluster the switch is supposed to be automatic and transparent. But start 2 nodes using dserver.sh/bat instead of server.sh/bat and assure two nodes see each other.
