Listener won't start anymore

3903641Mar 4 2019 — edited Mar 4 2019

I've had quite a bit of trouble connecting to a database connection. First I had to change the host name from "localhost" to "192.168.1.6" Right now I believe my listener isn't starting. I get the following error message when trying to connect to my once working database.

"An error was encountered performing the requested operation:

IO Error: The Network Adapter could not establish the connection

Vendor code 17002"

I run the command prompt as administrator and type lsnrctl start and get the follow error messages:

...

Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.6(PORT=1521)))

TNS-12545: Connect failed because target host or object does not exist

TNS-12560: TNS:protocol adapter error

TNS-00515: Connect failed because target host or object does not exist

64-bit Windows Error: 49: Unknown error

This may be a silly question but would restarting the internet have anything to do with it since my HOST is an IP address?


I can connect to SQL Plus however.

Thank you for your help.
