SQL Developer - can't connect, listener does not currently know of SID/service name
0
I know this is a common problem, I've tried everything I could find online and nothing solved my problem. I even uninstalled Oracle 11g XE and SQL Developer, deleted every file I could find and reinstalled, didn't help anything.
I can connect perfectly through the SQL*Plus command line and CMD.
I never had this problem but since today, when I try to connect with DQL Developer I keep getting this error:
AND
This is my tnsnames.ora file:

I was even so desperate to try that, but that didnt work. ... but ... I turned off my computer, went away for a bit and when I was back I tried again, for some reason it worked again... ! Weird because restarting didn't do anything before. Now it is fixed for some reason. Such a relief. Hope it stays this way now because it need to get some work done. :)

Typically when I don't see a service listed, I run an alter system register which flushes the servicenames to the listener vs waiting on the listner to poll and find them itself

Does

I was even so desperate to try that, but that didnt work. ... but ... I turned off my computer, went away for a bit and when I was back I tried again, for some reason it worked again... ! Weird because restarting didn't do anything before. Now it is fixed for some reason. Such a relief. Hope it stays this way now because it need to get some work done. :)

Restarting your laptop would mean your listener was restarted, which is what was probably required.
