hello,
when I try to query v$pwfile_user,I get the error ora-600
internal error
ora-00600-internal error code,arguments :[12333],[7],[5],[49],[],[]

I am also not being able to connect as internal/oracle.
its saying invalid username/password.
should I recreate the password file as pando said,I also made
remote_login_paaswordfile=shared
still it does not work.
bye
