SYS$REM_XXX logicals

[Ronny_7]

I have a customer with ES40 running on OpenVMS V7.2-2 with DECNET-OSI.

When she telnet into the system, she can see these logicals,
SYS$REM_ID
SYS$REM_NODE
SYS$REM_NODE_FULLNAME

But when she set host into the systems, these logicals are not there.

Any advise?

Ronny

Hello Ronny,

sys$rem_XXX logicals will not get defined
if you login to a node running OSI with a local namespace, if the node you are coming from is not in the local namespace. (i.e.,
there is no way to backtranslate the address to a name).

As a workaround, you can define the node in
the local namespace.

The above is true assuming you have enough JTQUOTA to hold all logical names.

Hi Guy Peleg,

Forgive me for my limit knowledge.
What do you mean by local namespace?

How do you define the node in the local namespace?

Where can I find the information regarding the JTQUOTA?

Ronny,

JTQUOTA limits the amount of logical names a
user can have. JTQUOTA can be found in
the UAF record of a user.

$MC AUTHORIZE SHOW username

Usually a value of 8192 should be enough.

As for namespace, you need to register the node
in the local database. Use the DECNET_REGISTER
utility to add the node information

$ MC DECNET_REGISTER

Option number one will show information about
registered nodes and option number two will let
you to register a node.

I hope this helps, if you need more guiding
I suggest you log a service call with your
local support center, it should be a short
call :-)

Hi Guy Peleg,

Thank you for your detailed reply.

Hi Guy,

I have ran MC DECNET_REGISTER and the problem node is already registered.

This is a two nodes cluster and this problem only happens on one node.

My customer is using SET HOST 0 command.

check where DECnet is trying to back translate the name by using the command
mcr ncl show SESSION CONTROL BACK SEARCH PATH

Is the node connecting via DECnet or DECnet over IP?

What is the result of SHOW USER/FULL for the username - this will indcate what VMS sees as the source of the login.

Hi Ian,

Thank you for the advise.
The customer has logged a call with the support centre.

The support centre will take over from there.

In case this is a problem with backtranslation
(e.g. you get a message similar to "failiure to
backtranslate address" during login), you might want to check if the users were granted the
net$examine rights identifer.

Hi Martin,

Thank you for the advise, I will take note of that.
