Connection refused, only from remote systems
I am facing the following problem:
Connectin my Database from an EJB.
If the EJB and the Database are on the same system, everything works fine. If the Database is on a remote system, I get the following error:
java.sql.SQLException: I/O-Exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=135294976)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
I know that code 12505 seems to be a listener problem, but the listener is running fine, I can connect the database via SLQplus-Client from a remote system, I checked twice the SID and everything seems fine!
Someones got an idea, please?
