I am new using Oracle and I have just installed the 10g database and the 10g developer suite.

I am trying to run reports to teach myself. I run the reports wizard and I get a window
to connect to the database from the "Query builder ", I enter scott + tiger + orcle10g
I get this error:
"REP-0501: Unable to connect to the specified database
ORA-12154 (See ORA-12154.ora-code.com): TNS:could not resolve service name "

I can connect to the database using the PLSQL window as scott/tiger
what Ido I do to be able to connect using the Reports builder
is there a command that I can use to find out the name of the database

Any info anyone can provide?

TNX,

Nestor :-)
