I have just recently installed Oracle 9i. I am a very novice level user... When I installed it and opened Oracle SQL*Plus and entered the default user name and password (scott tiger) I was able to Log into Oracle. After the weekend (Restarted the system) and now I get this ORA-12560 TNS:protocol adapter error. How can I resolve this problem?Will I need to give some "Host String" or what? The most amazing thing is that 2 days back it was running and now suddenly it is not working... I hope someone will give me the method to come out of this problem.... Note that I am/will not be using any feature related to Internet or Network or anything else. I will use Oracle as a Storage device(Back End) with my VB6 application frontend....
OS: Windows XP SP1
Firewall : ZoneAlarm installed (If it helps)
