This error with the words:
"[INS-20810] Target or command to 'Oracle Net Configuration Assistant' not valid" is shown at the end of installation when the net configuration has to be installed properly.
And then suddenly some error messages with the words "An error occurred during runtime", pop up.
Then if I ignore the error messages and click skip, the installation gets completed leaving the essential net configuration and other database set ups uninstalled. Then when I get into sqlplus and enter the correct username and password too, it shows me an error with the message "ORA-12560: TNS:protocol adapter error".

I have recently moved from TCP to TCPS Connection. I can confirm that all my connection parameters are right and properly set. tnsnames.ora and sqlnet.ora is under oracle_home/network/admin folder.
I am trying to connect and getting below error message:
An error was encountered performing the requested operation:
Internal Error: Fetch error message failed!
Vendor code 17001
Looking for suggestions to fix issue.
Make sure that the Oracle Client "bin" directory (e.g. $ORACLE_HOME/bin) is in your PATH environment variable.
I am trying to find out with SQLEXPRESS is installed on a server by running the following
sqlcmd -S LT1183 -U uname -P pass123 -Q "SELECT ##servername"
If it is installed it gives out the server name but if its not, it throws the below error.
Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : Login timeout expired.
Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : TCP Provider: Error code 0x2AF9.
Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.
I am looking for a way to suppress this error and instead show a custom error message. Is that possible?
Thanks in advance.
This may not be possible with sqlcmd, since the error stems from connecting the the server, which upon error immediately terminates the sqlcmd.
if you can use powershell, you may find some luck using invoke-sqlcmd.
Powershell Try Catch invoke-sqlcmd
I have installed Oracle 11g on my Windows 10 machine. I followed all preinstallation requirements.
When trying to log in to the Enterprise manager via this link:
https://localhost:1158/em
I get the error:
Internal Error has occurred. Check the log file for details.
I have found log files and it looks like this is the relevant entry:

I have tried to set the unique name in environment variables, I thought maybe Java was the problem so I updated my JDK to 8. I am still getting the same error, and my SQL Plus will not open, as soon as I put in the correct credentials it closes. Also I have configured a Listener and tested, test was successful.
I managed to fix the issue, turns out it was a time zone issue. The DB time zone and computer time zone were different. Thus the DB Console would not start and was giving the error "EM daemon is not running".
I fixed it by following instructions here.
Also note before I did that I completely uninstalled Oracle and reinstalled it. There were some issues on that install that were causing SQL not to run. But the above is what fixed the Internal Error I was getting.
Make sure the SYSMAN database user is not locked.
select username, account_status from dba_users where username = 'SYSMAN';
If the account status is not OPEN then
alter user SYSMAN account unlock;
Try restarting dbconsole
$ emctl stop dbconsole
$ emctl start dbconsole
For the last month I have installed and used Oracle 11 XE, but this morning I restarted my computer and installed new updates from Windows. Now I cannot get the database to work. I know this caused it because I was using SQL Developer right up until I restarted. I get this error when attempting to run in SQL Developer
An error was encountered performing the requested operation:
IO Error: The Network Adapter could not establish the connection
Vendor code 17002
I went to Service and made sure my OracleServiceXE was running, which it was. I tried starting "OracleXETNSListener" and got this message:
The OracleXETNSListener service on Local Computer started and then stopped.
Some services stop automatically if they are not in use by other services and programs.
I then went to CMD and typed "lsnrctl status" and got:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=<host name>)(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener

TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
64-bit Windows Error: 2: No such file or directory
Now at this point, almost everything I googled told me to start the listener and if that doesn't work run as admin. I did both of those things, but it didn't work.
running normally in cmd:
Starting tnslsnr: please wait...
Unable to OpenSCManager: err=5
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
running as admin:
Starting tnslsnr: please wait...
(note: it stalls for 2 minutes)
TNS-12560: TNS:protocol adapter error
To complicate matters, my computer told me "We couldn't finish installing updates" and that makes me hesitant to uninstall the updates.
I constantly get the following error when opening the test explorer in VS2013:
Failed to initialize data storage for staging test results as it threw the following exception:
'A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Error occurred during LocalDB instance startup: SQL Server process failed to start.
In the EventViewer I see the following entry:
Source: SQLLocalDB 12.0
Message: Windows API call WaitForMultipleObjects returned error code: 575. Windows system error message is: {Application Error}
The application was unable to start correctly (0x%lx). Click OK to close the application.
Reported at line: 3728.
Does anybody have the same problem and know how to get rid of this error?
Best regards
Yannik
Finally, I found a solution that worked in my case.
Delete the instance folder of local db called "v11.0" (C:\Users\theUser\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\v11.0)
Start cmd window and execute the following command: sqllocaldb create "v11.0"
After this, the problems within the test explorer were solved.
Yannik had the solution....local DB (v17) is now called MSSQLLocalDB.
Delete "MSSQLLocalDB"
(C:\Users\theUser\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\MSSQLLocalDB)
Create a new one.
sqllocaldb create "MSSQLLocalDB"
