Using SQLPLUS 18c on windows 10pc, which has Oracle XE 18c
get invalid password response when try to connect to 19c EE on ODA
TNSPING reached the 19c database
Using same account and password from SQL developer on same PC,
I can connect to the 19c database on the server.
thanks
tried sqlplus uid/pwd#my19cdb
get invalid uid/pwd message
tried tnsping my19cdb works
tried connecting through SQLDEVELOPER and it works
The password in the .bat file I was using to initiate sqlplus had special characters and these were not quoted properly. When i change the password to have no special characters, it worked fine. So Jeff had the right answer.
I have Windows 8 and Oracle SQL Developer. When I tried to connect to a remote server, it give me v$session.osuser error and vendor code 17190.
Do anyone know what this means? I have tried to search for the vendor code 17190 but nothing related to Oracle.
Thanks
I've installed Oracle client in my machine, when I'm trying to connect to the oracle database server from Oracle SQL Developer am getting the following error:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
But am able to connect to the server using sql plus and TOAD as well from my machine. What is the issue if Toad connects to the server why cant my Oracle sql developer could not connect??
checked all the possible solutions like:
tns strings checking, telnet to the server and its port,
changing the oracle home in the sqldeveloper->tools->preferences->database->advanced tab.
None solved my issue. Is this the firewall issue?
If it is so how am able to connect using TOAD/sql plus ??
UPDATE: I'm connecting to the Oracle database server using the VPN.
Any help is much appreciated.
Thanks in advance.
I have oracle 9i already installed in my machine. I am trying to connect to the oracle but while connection i am getting "ora 12560 tns protocol adapter error" type of error. i have tried it with the default pass scott/tiger , system/manager..
When i tried to connect to the oracle using default credentials i am getting the above error.
is it the problem with the username and password ? if so how can i get the username and password which is already set ?
IME, ORA-12560 means the Oracle Universal Installer messed up your listener configuration.
Assuming you have an Oracle 9i Server installed on your computer, here's a list of things to check.
does "lsnrctl status" show your database instance?
does "tnsping my_service_name" work?
do tnsnames.ora and listener.ora contain entries for your database? Are the hostname / port etc. correct?
If the configuration is wrong, your best bet is to start netca, remove your existing listener configuration and re-configure it.
One question, though: Why do you want to run Oracle 9i? Do you have to support some kind of legacy application / database? (Oracle 11gR2 is so much nicer than 9i)
Start -> Run -> services.msc
Select the oracle service name and right click on it then select start.
I am a new user in Oracle. In Oracle SQL Developer, whenever I want to create a new connection and fill the "New Database Connection" form, it gives me this error: -
ORA-12560: TNS:protocol adapter error
Please Help.
To add more to my comment on the question...
Ensure your database is open (has been started up).
Start all oracle services for your database
Start the databases listener (lsnrctl start)
Startup your database instance (startup open <database_name>)
Also, ensure the database you are trying to connect to has an entry in the tnsnames.ora file your SQL Developer is using (depending upon your setup you may have a tnsnames.ora for both your oracle client and database software if they are on the same physical hardware like your PC or laptop).
I've faced that kinda problem also and I've tried stop all of oracle services and start it again. But unsuccessful. Eventually, I've needed to install Oracle again which can solve this problem.
