Hello, boot the system in single user mode and change the "root" password and login to the system with new password.

Thanks, -Bala S

boot into single user mode with
>>> b -fl 0 "yourdisk" for example dka0
# mount -u / (make boot rw)
# mount /usr
# mount /var
# passwd
# init 3 or Control D (continues to run Level 3)
login with root and your new password

Hello, did you get a chance to reboot the system in multiuser mode after changing the "root" password? if not can you please reboot the system and see all the files are available or not.

Surapol,

you have installed a new OS from CD!
Therefore any application information is gone. If you have the DB-Data on other disks
it should be possible to rescue your system
if you have a valid backup like vdump of root,
usr & var Filesystems on tape, else you are lost.
