I have googled this error: "ORA-12541: TNS:no listener" ---- and found many suggested solutions in forums but nothing has fixed my issue.
I've installed Oracle10g in the past and didn't have problems. Not sure why it's an issue now. I had to upgrade to receive dmps from oracle11.
I've tried 6 different Oracle installs and it's possible that installations are colliding.
I'm referencing my latest Oracle Installation:
Oracle Version: 11g Release 2 (11.2) for Microsoft Windows (32-Bit)
TOAD seems to be unable to cannot connect to 64bit database so I've used 32bit.
The goal: install Oracle 11.2.0 and connect TOAD 18.104.22.168 to my local oracle database.
I have included 3 screenshots:
3) ToadHome Editor - I am using my latest install named HOME2 but it's in the folder 11.2.0\dbhome_5
When I run the CMD: c:\app\kkearney\product\11
it says listener has already been started.
Environment Variables PATH: C:\app\kkearney\product\11
In TOAD I'm trying to login as User: SYSTEM
I have tried many derivatives of this but nothing has worked. Thanks for help in advance!
