[Solved] IO Error The Network Adapter could not establish the connection
Problem:
An error was encountered performing the requested operation:IO Error: The Network Adapter coule not establish the connection Vendor code 17002.
Solution:
Ensure oracle or mysql server is running, if it is not running then start the server by the below command,
lsnrctl start (to start the sql in other system).
Now you can connect without any issues.
Hope this helps…..!! If you have any other solutions kindly post in the commands section.
The Network Adapter could not establish the connection. I still have the error for some reason after i went through your steps
the same error still show could not establish connection.
Please post the error and all the steps you tried to understand and help you better.
In my case, the listener is getting connected..
