Yes. It is.
The question asked during installation will only put the value in the default
mcc_login files, and use this option during installation.
You can switch back to MIR simply by redefining MCC_DNS_SELECTION *and*
killing/restarting all MCC processes (I suppose you are on ULTRIX).

LOCAL_NS is a dummy value used as namespace name when using MIR selection.

By switching back to MIR for DNS selection.

Yes, you can. You just need to be aware that you will have 2 different
configurations, that cannot run at the same time, and be very careful with
some potential problem with names stored elsewhere than in the namespace :
If you create an alarm rule containing a reference to an object called
DNS_NAMESPACE:.something, the rule will not work in a MIR namespace since
the object something will be called LOCAL_NS:.something.
Hope this helps.

I am doing it in VMS, there is no shutdown procedure for DECmcc. What
are the MCC process that I need to kill in VMS? I don't think there are any
expect the MCC_EVC and MCC_EVL.
>>LOCAL_NS is a dummy value used as namespace name when using MIR selection.
So that mean there isn't actual a namespace name "LOCAL_NS" when using MIR
and no DNS was used.
>>>How can I change
>>>the existing namespace name to LOCAL_NS?
>>By switching back to MIR for DNS selection.
What I means is if the existing namespace name is HKCORP, is there any utility
or how can I change/swap to another namespace name, if I have more than one?
Also let me confirm that if I want to use MIR, all I need to is redefine the
MCC_DNS_SELECTION logical, there is no need to change the namespace name to
HKCORP. Am I right?
OK. If I use MIR, can I use the utility MCC_DNS_SETUP.COM option 2 to generate
a register node4 command procedure? I tried that, it seems that it require
a DNS server.

act on DNS and you arn't using it.
Do a SHOW SYSTEM and look for process names that contain MCC_ and stop
them. The bottom line is you need to release all shared access to the
MCC_MAIN stuff at least.
When not using DNS (Distributed Name Services), DECmcc inserts the text
"LOCAL_NS:" when ever it would normally put the namespace name so that
procedures that might parse output can be consistant and not need to
know what sorta name services you chose.
I left a reply in another note yesterday that explained more about
about changing namespaces.
