Can not login to the sql plus using oracle 10g developer suite sql plus gui
857264Jun 18 2011 — edited Jun 19 2011I am just a starter to Oracle developer suite.Actually I would like to self-study oracle form and report for job interview.
But I have a problem from the start.I just use the Oracle 10g XE for database.For table creation,it is ok I just use oracle database home page and it is very easy to use.
So I have oracle developer suite 10g and oracle 10g xe already installed in my computer.And the hr account has already been unlocked and is ready to use.So I can use sys,system and hr account to access to the xe database.But I have a problem when accessing sql plus to login.There has username,password and host string.I surf and find in the internet and recognise something that there is no need to fill in the host string unless you need to access to a specific database.That means it is with user name and password but I just use every account but still can't login.It constantly shows "ora-12560:TNs:protocol adapter error".I need urgent help!I think somebody can help me out.thank you very much.
