RE: password iin dba_users - Oracle 11

I understood that the old style password hash was there to support a database which has been migrated from 10g to 11g and converted to use the new case sensitive passwords. As an ex 10g user changes his password or has an alter user command run against him he changes from the old hash to the new hash (which also includes case sensitivity) which is the reason why there is room to accommodate both hash versions.

I think I need to spend a bit of time researching this one, although currently we have no 10g to 11g migration plans, just new 11g builds.


It didn't work on 11g, simply due to the fact that the password hash is no longer available in DBA_USERS.

It is however available in sys.user$ as Ian pointed out.

As referenced in Pete's blog, the old style password hash is still there, presumably for non-11g clients, though I haven't made any attempt to verify that.
