Kurts explanations remembered me of the way, many oracle documents are seperated into public and internal parts: In many documents, lines starting with a @ are shown only 'internal'. If my memory serves well, this goes back to the old TAR-handling forms- application. maybe you want to ask the support analyst if this can be the case in Doc:465968.1 too.
Take this information with the grain of salt that any recommendation on a public mailing list should be taken with.When I look on support.oracle.com, I see the name of the .sql scripts is missing for those steps.When I look at support.us.oracle.com (an internal Oracle site), I see for step 11, substep 4:sqlplus "/ as sysdba" @wdbigra.sql portal For step 11, substep 7, I see: cd $OH/rdbms/admin sqlplus "/ as sysdba" @utlrp As others already have surmised. I hope this helps. Kurt
