I'm trying to run the demo for warehouse builder that appears at oracle, but I´m getting this error when I run the source loadall.tcl:
OMB01118 error java.sql.sqlexception: The network adapter could not establish the connection.
I've been reviewing some of the answers you have given before, but it didn't work (the telnet to localhost 1521 doesn't work, etc.).
Thanks for your help!!
