John,

  I'm not sure as I've never done that - I've only relocated the datafiles, so all I've ever done is adjust the path to them. Something for me to try, I guess! To open a database with resetlogs:

   alter database open resetlogs:

That'll do it - I'll try that renaming of a datafile soon. (My instinct says you can't - that information is located in the data dictionary and I don't think renaming the datafile in a controlfile creation will update that - could be wrong!) How 'bout it gurus, what do you think!!
