/*/ora/*/*/*.[Dd][Bb][Ff]
/*/ora/*/*/*.[Aa][Rr][Cc]
/*/ora/*/*/*.[Rr][Dd][Oo]

Take *.[Aa][Rr][Cc] for example. it will exclude all the file suffix with .arc or .Arc ….

NB:

1. Include lists can only include files and directories that are listed in the exclude lists so that they are not excluded.
2. There’s also a thread about include_list & exclude_list here http://www.symantec.com/connect/forums/how-create-unix-exclude-list
