We copied our production database over to our test instance by copying the data files. The users are now having trouble getting into the Oracle Application software on the test instance. It keeps telling them they have the wrong password. They have tried their production and test passwords and nothing works. Nobody can currently get in. Is there something we need to do to get the applications to work after copying the dbf files? We used rcp to do the copy on AIX.

Thanks for any help.
