Comment:

I came across a DEC 3000 recently. It was running OpenVMS. It has an odd host name (WPCQ), i think. I asked a friend who knows VMS to change it for me. I gave him telnet access. He was trying to change it to 'below'. However, he somehow messed up and now it won't boot. Actually, it will, but it gives me a 'User Authorization Error' when I try to log on. Can anybody help me? What are the steps to change a hostname?

Well,.....
It's easy to change just the nodename, but
a lot of applications needs to be
reconfigured, like DECnet, TCPIP,........
OK,.......to get you going.....
>>> boot -flag 0,1 'device'
SYSBOOT> SHOW SCSNODE
SYSBOOT> SET SCSNODE "new_name"
SYSBOOT> SET /STARTUP OPA0:
SYSBOOT> CONTINUE
this will finally get you a "$"
$ SPAWN
$ SET DEF [VMS$COMMON.SYS$STARTUP]
$ @VMS$INITIAL-050_VMS
$ SET DEF SYS$SYSTEM
$ MC AUTHORIZE
UAF> now change your account
UAF> EXIT
$ MCR SYSGEN
SYSGEN> SET /STARTUP SYS$SYSTEM:STARTUP.COM
SYSGEN> WRITE CURRENT
SYSGEN> EXIT
Now it's time for a reboot....
If the node ends up with SYSBOOT>
just type in CONTINUE.
Hopefully you now has a node with a correct
name and that you can login.
You need to change the nodename in the file
SYS$SYSTEM:MODPARAMS.DAT, otherwise you get
the old name back next time you run AUTOGEN.

Oops. I just found out that the Batch queue sitll thinks that the node name is WKRQ. What can I do to fix this?

Do you mean the queue has on=WKRQ ?
Do a
STOP/QUE/RESET 'queue'
START/QUE/ON='newname::' 'queue'
or a
STOP/QUE/RESET 'queue'
DELETE/QUE 'queue'
INIT/QUE/BATCH 'queue'
