Links/Ports in DECNet Phase IV (insufficient resources)

[Kirsten Knüttel]

On my OpenVMS Alpha (VMS 7.3-1) appears DNA Error= Insufficient resources (DECNet 7.3-1 Eco 2). And we have Problems to connect via Decnet on this machine
(e. g.
dir nero::*
%DIRECT-E-OPENIN, error opening NERO::*.*;* as input
-RMS-E-FND, ACP file or directory lookup failed
-SYSTEM-F-LINKABORT, network partner aborted logical link)
So I think there are not enough ports or links for these connections. What must I do, how can I increase the number of the links or ports?

I hope somebody can help me.

Regards,

Kirsten

Kirsten, you may check with:

$ MCR NCP
NCP> SHOW EXE CHAR ! look for line maximum links
NCP> SHOW KNOW LINK ! shows active links
NCP> SET EXE MAX LINK nn ! sets max. volatile
NCP> DEF EXE MAX LINK nn ! sets max. permanent

Hi,

sorry, it was too much in my brain.... it was decnet phase V.....

MCR NCL
SHOW NSP ALL CHAR
SHOW OSI TRANSPORT ALL CHAR
will show some things that can be changed by
@ SYS$STARTUP:NET$CONFIGURE ADVANCED

Kirsten,

NCL> SHOW NSP ALL
NCL> SHOW OSI TRANSPORT ALL

will also show

Currently Active Connections = ...

In which context does this error message get returned ?

There may also be a shortage of other OpenVMS-related resources.

MCR NCL
SHOW NSP ALL CHAR
SHOW OSI TRANSPORT ALL CHAR
will show some things that can be changed by
@ SYS$STARTUP:NET$CONFIGURE ADVANCED

start with max connections.

Kirsten,

if you look at the documentation (DECnet-Plus NCL Reference Manual Chapter 20.4.4 Event Message):

http://h71000.www7.hp.com/DOC/73final/6500/6500pro_024.html

you could see, that Maximum Connections already active would be reported with a different error code (0x43).

Hi Volker,

I've looked in "DECNet Plus Problem Solving". Chapter 6.8 "Correcting Insufficient Resource Problems"

With
show nsp all
I've seen 200 maximum transport connections and with
show osi transport all status
I've seen 197 active connections
so I think I'm on the right way. Or am I not?

Regards,

Kirsten

Kirsten,

so you might be running out of OSI TRANSPORT connections...

MC NCL SHOW OSI TRANSPORT ALL will show both Current Connections and Maximum Transport Connections.

You could increase this parameter dynamically:

NCL>set osi trans maximum transport connections 201

Kirsten,

if you need to increase the OSI transport maximum transport connections, you may also need to increase OSI transport maximum remote NSAPS.

You would want to check, whether all those OSI transport connections (i.e. links) are really required for your applications:

NCL> SHOW SESS CONTROL PORT * ALL

It might be easier to use the NET$MGMT DECnet-Plus Motif network management tool when looking at 'links' etc

$ SET DISPL/CREATE/NODE=your-node/TRANSPORT=your-transport
$ MCR NET$MGMT
