When this occurs, the service handlers for the TNS Listener become "Blocked" and no new connections can be made. Once the TNS Listener receives an update from the PMON process associated with the database instance telling the TNS Listener the thresholds are below the configured limit, and the database is now accepting connections connectivity resumes. Solution There are error code 10061 different ways to check if a database instance reaches the maximum number of processes on Oracle 11gR2. One of the quickest SQL see below: select * from v$resource_limit where resource_name = 'processes'; If this is the case, to fix this Oracle error, increase the PROCESSES parameter value to allow the Oracle database Listener to spawn more server process as required in your environment. It might be further investigation required though. Update: 16-Dec-2011 Sometimes when listener throws a TNS error the number of actual processes can be below the limit. See below why this can happen. When the listener believes the current number of connections has reached maximum load, it may set the state of the service handler for an instance to "blocked" and begin refusing incoming client connections with either of the following errors: ora-12519 or ora-12516. Once the TNS Listener receives an update from the PMON process associated with the Database instance telling the TNS Listener the thresholds are below the configured limit, and the database is then accepting connections connectivity resumes. The listener counts the number of connections it has established to the in

You shouldn't expect anything like "Your user name is OK, but your password is one char too long" etc. Presuming you're sure of your username and password (this exact same code may have worked before in the same JVM), the issue is possibly that the DBMS is getting too many concurrent connection requests, and can sometimes fail some of these identical at
