Resetting the root password on a Solaris server

I had to use the following step to reset a the root password on a Solaris system the other day. You will need physical access to the system to use these steps.

  1. Press Stop-A on the console or Ctrl-] and send brk from a remote console connection to access the Open Boot PROM (OBP).
    NOTE : If you are using TeraTerm-Pro, you send a break from the menu.
  2. Insert a bootable Solaris CD/DVD and boot into single-user mode with boot cdrom -s
    If a JumpStart boot server is located on the system’s subnet, and the system was properly configured for JumpStart, you may instead boot over the network into single-user mode with boot net -s
  3. Make a mount point within the /tmp file system by typing mkdir /tmp/mnt
  4. Mount the root partition of your boot disk in /tmp/mnt
    e.g. #> mount /dev/dsk/c0t0d0s0 /tmp/mnt

    NOTE : To check the device name use the format command.

  5. Edit /etc/shadow with TERM=vt100 vi /tmp/mnt/etc/shadow
  6. Remove the encrypted part of the root password (the second field; fields are separated by colons), save, and exit.
  7. Unmount the file system with umount /tmp/mnt
  8. Reboot the system and assign a new password at a shell prompt with the passwd command.

If you are unable to run vi above, you can edit /etc/shadow using the ed editor.

# ed /tmp/mnt/etc/shadow
s/:………….:/::/ (Note: there are 13 dots in the second field)

Resetting the OMS password

We’ve had an Oracle Manage Server (OMS) running here at work for some time now. I think it was setup by a DBA who worked here years ago. The previous DBA didn’t use it so when I came to the job he told me to just login locally to OEM and not worry about using it.

I had some spare time the other day and thought I would have a look into what it could do. One of the first problems I ran into though was that I had to reset my password. Of course I didn’t have the admin password, and the last DBA doesn’t work here any more. So I had to find out how to reset the sysman password.
