I have a database on sever TEST and when i connect to database via sqlplus from same machine i am able to connect and everything is fine. But when i am trying to connect through jdbc calls from a java program from a webserver i am not able to connect and then i found listener is down on server. I want to know that even if listener is down on and if i make connections from same machine on which database resides via sqlplus works or not. Does it use any bequeath process or something for this type of process. Please advise
