NDPSM Loads Very VERY Slowly

We run NDPS on a NW6.5 server (dual 3GHz Xeon processors, 2GB RAM). The
server hosts 590 printers, all using the SNMP gateway. When we reboot
the server, it takes a very long time to load all the printers -- as
long as 45 minutes. Is this normal?

Thanks,

What gateway do you use? PH or NDPSGW?

Both gateways are loaded on the server. Is there a quick way to tell
which PAs are using one vs the other? I created 90% of the printers
myself and I always select "Novell Printer Gateway (SNMP)". Is that not
correct?

Re: NDPSM Loads Very VERY Slowly

Prior to the ndpsgw.nlm gateway the novell gateway consisted of two modules.
ndpds.nlm & ph.nlm If you were ever using the old novell gateway or were
using any 3rd party gateways the load time could be very slow.

1>.You can run a report that will show the gateway load string for each
gateway.

Start Novell Remote Manager ( NRM ) and go the NDSP Manager healthe
screen.
Select Advanced Button at the bottom of the page.
Select the generate report button and then select the 'Gateway Load String'
checkbox.
Run the report.
check to be sure that none of the printers are loading anything other than
the NDPSGW.NLM gateway.

2>.Type m ph* at the server console. If the reported results show that a
PH.NLM is loaded then you have an artifact left from the old gateway. One
or more of your printers is loading this module and this will cause
significantly slower load times. You can run a utility called PACVRT.EXE
available from the Novell download site and select both Novell gateways as
the source gateway and the Novell SNMP gateway as the target gateway. This
utility will fix issues 1>. & 2.>

3>.You can run a diagnostic on the NDSP Manager to see where the load times
are taking so long.
When the NDPS Manager is unloaded type:
'NDPSM' and hit ENTER. *** Do not select the PSM and continue loading the
Manager.***
Go back to the main server console and type 'NDPS Manager Debug Display
+Gateway +Time +File'. Then hit ENTER. ( This will load the internal
diagnostics for the Manager. )
Go back the NDPS Manager console screen and select the manager object and
continue loading the Manager. Let the Manager load. After the manager is
loaded go back to the main server console and type 'NDSP Manager Debug
Display OFF' ( You have to let the diagnostics close the file before you
will be able to access it.) The path to the diagnostic log file is
SYS:\SYSTEM\NDPSM.LOG

The free NDPSAddr, using the /PDS or /ALL
switch.

Sure enough, I found a couple dozen printers using the PH gateway. I
converted them but haven't restarted the NDPSM yet. <crossing fingers>

Thanks for the tips; these look like just what I need to whip this thing
into shape.

Assuming I get 'em all using the SNMP gateway, is it okay to put 600+
printers on one dedicated server?

Thanks,

Doug

YMMV I suppose:

http://support.novell.com/techcenter/search/search.do?cmd=displayKC&docType=kc&externalId=10060025html&sliceId=&dialogID=1774673

"Cases of over 1000 PAs on a single NDPS Manager have been known to exist on NetWare 5.1 on PIII-class hardware in clustered environments. Unless you are in a clustered environment where fail-over tolerance is high Novell recommends you should not place more than 200 to 300 PAs on one NDPS Manager. If you must place a larger number (400+) of PAs on a single NDPS Manager make sure your LAN card is intelligent (CPU off-loading)."

Yes. One guy in here reported having 1000+ PA's on a server.
Keep in mind though that despite he was using pure NDPSGW it still took 10
minutes to unload/load the manager.

Are you sure you want all printing in your organisation to be dependant on
one server ?
With these amount of printers I would seriously consider creating a 2 node
cluster.
Or divide the PA's over two servers, so that one server is down, people can
still print to the next office...
