Why is TOAD able to start a debugging session and SQLDeveloper always comes up with:
ORA-30683: failure establishing connection to debugger
ORA-12541: TNS:no listener
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
Same client, same OCI driver, same host, same database, same login, same procedure.
I don't get it.
I have been told that SQLDeveloper requires a "backward connection" from the database to the client, which is prevented by some firewall settings in the company.....
Ok, but why does TOAD not require this, where is the difference?
Is there anything I can do to convince SQLDeveloper to do it just the same way (without having to convince a lot of people putting holes in firewalls)?
