Hi ALl,
I have donwloaded and installed SQL developer 3.x.x 32 bit bundeled with JDK 1.6_11. But when I try to connect to oracle database HR84DMO using the credentials:
user name - sys
password - oracle12
role - sysdba
host name - localhost
port - 1521
sid = HR84DMO
Please note that everything is installed on my own laptop running with windows 7 64 bit. I am getting below error
Status : Failure -Test failed: The Network Adapter could not establish the connection
Please also note that, I have created two databases running at the same time and I am not sure if they are running with the same port 1521 because, when I started first database HR84DEV it certainly would have started with the port 1521 but I also started the database HR84DMO to which I am connecting to, at the same time.
Is there a port clash?
I can connect to database using the same credentials from command line and database is also running.
I am not really shure of this, just guessing that this might be the problem.
