I just upgraded our Netware server from sp3 to sp6 last night.  Didn't really detect an issues initially after the upgrade.  I installed the manadatory cifs and edirectory updates and the recommended tcp update.  I'm pinging the inside address of the server and occassionally notice some really high latency times...ranging from 1000-2500ms for about 10-15 seconds and then it goes back down to under 1ms.

The server is running as a file server, Groupwise, Intranet (php and mysql), and is running arcserve.  It's used by about 25 people inside the office and externally by about 25 people via ssl vpn.

Any idea what would cause the latency and how i can determine where it's coming from?

I'm doing some additional troubleshooting.  It appears that the times jump up when I'm doing a search in the intranet where the page is calling a lot of records in the database.  I had one query in particular that was resulting in over 10,000 records.  I modified this query to only show about 1000 records and haven't seen the large spikes as often.  Is anyone aware of any known performance issues with the mysql version that comes with netware 6.5 sp6

When you're doing your PING tests and see these spikes in latency, do you see anything corresponding in the health log?  Have you tried monitoring the server with NoRM to see if any of the stuff that watches "go red."

Here's a TID on TCP/IP troubleshooting with SET commands, that may (or may not) help: http://support.novell.com/docs/Tids/Solutions/10013542.html

Have you heard anything about issues with mysql post sp6??

No, but that doesn't mean anything ;)

A large query result set spikes PING latency, eh?  Is this result set actually going out on the wire or is it populating a web page that also resides on your server?

it's displaying on a page that resides on the server.  i've got a continuous ping going to the internal ip address of the web server. If i run the old query upon excecution the time immediately jumps up.  after modifying the query it stats at under 1 ms.  i plan on leaving this query like it is now, but am concerned that we might encounter this problem in the future since our db has a lot of data in it.

found this posting linking to a novell tid: http://www.webservertalk.com/message1751386.html

do you think this could be my issue?  this is referening sp5, so the instructions are not quite right for sp6.  i do notice that i have a 0.0.0.0 if i go to Ip Address Management - Show Configured IP Addresses in Remote manager

I'll research this error some more, just wanted to see if you thought i was heading in the right direction.

Shineon,

Does the 0.0.0.0 normally display in the ip address list?  do you see it on your server?

Also, on the ip management page with all the protocols, there are a lot of them set to 0.0.0.0, is that normal?

I'll give this a try tomorrow, just curious if it doesn't belong there, how'd it get there.  

As always, thanks for your help.
