Hi,
I am trying to connect to our running Oracle database. After not being able to establish a connection with OCCI I wanted to try to use SQL Developer which results in the following error message:
Status: Nicht erfolgreich -Test nicht erfolgreich: I/O-Fehler: The Network Adapter could not establish the connection
OK, after reading some other threads:
Connectivity issue in SQL developer.
I have turned off:
- all firewalls,
- checked if the listener is running,
- double checked the connection details.
While this issue seems to occur on my VM whereas I am able to connect to the same database with the same version of SQL Developer and JDK on my host machine. I have also double checked the connection details by myself and by a colleague.
Any hints are highly appreciated.
Best,
Paul
