I installed Oracle11g on Windows XP. Initially it ran well; however, after I rebooted the machine I was no longer able to connect to the database. When I attempted to log in with sqlplus, the following error message appeared: "ORA-12560: TNS protocol adapter error"

What should I do?

Thanks very much,

Tim Mann

// *Cause: A generic protocol adapter error occurred.

I am sorry to see that both the search function on this forum & GOOGLE are broken for you.
Please be patient until repairs are completed.
