Yes, you've got the right place for this article! Look down slowly!
Did the client ever encounter this error with the server?
ORA-12518 TNS: Listener fails to distribute client connections
is not the server on this machine does not write service name, direct connection also not connected, prompt this error?
ORA-12560:TNS: Protocol Adapter error
Did you search for a whole bunch of solutions on the Internet, what set oracle_sid ah, configuring monitoring Ah,
Oracle Service Restart Ah, there are a lot of statements, what Sqlplus/nolog connect/as sysdba and so on ...
There is also a strange phenomenon is that the Oracle service starts normally, no error, whether the service inside the start or command line start,
And there is no oracle.exe in the process.
But the server is not even connected to the machine, is it?
Not at the end of the deal, is it?
That's right! I didn't solve it too! I look for ah, spent the whole morning, finally found the reason!
Oraspawn.dll
This magical DLL was deleted by 360!
Back up the DLL in the Recycle Bin, restart the server, OK!
So it's settled .....
