Hi, I'm facing a strange behaviour on my tomcat webserver with a servlet. I'm using Oracle 10g as the database and try to access it with my servlet. The doPost-method throws the following exception while trying to establish the connection to the RDBMS:
"SQLException: Connecting not possible: Listener refused the connection with the following error: ORA-12519, TNS:no appropriate service handler found The Connection descriptor used by the client was: localhost:1521 BTEN"
After starting my servlet, the connection to the database for other applications blocks with the same error message for a few minutes. After these few minutes connecting to the database is possible again!!! Restarting the database and the listener also helps...
