Hello,

I'm trying to create a View form (pg. 138 of 5.1 'Developing AR System Applications: Basic') to a remote Oracle database.
From the command line, a sqlplus query to the database is successful. When using the syntax documented on this page of the guide ('OWNERNAME.TABLENAME@LINK'), an error message is being generated:

A failure during SQL operation to the database:
Failure during SQL operation to the database : ORA-12154: TNS:could not resolve service name ARERR 552

Thanks for your helps!
