Re: Witango-Talk: Witango 5 / SQL Server 7

[John McGowan]

Hold on...  Why wouldn't you be caching application files or include 
files?  I've never heard of anybody not doing that in a production 
environment.  Does this server get a decent amount of traffic.  If so, 
the problems could be that you *aren't* caching.  Race conditions caused 
by different Witango threads trying to do the file IO for every hit 
might be the problem.

This is all speculation as I do not know the exact nature of the 
problems I've had with caching on Witango 5.  I only know that they do 
exist, and have been acknowledged by Witango and that the entire part of 
the app server that deals with that has been redone in 5.5 so it 
shouldn't be a problem anymore.  I haven't upgraded yet though so I 
can't say for sure.

No - it's not. Did you see the problem get better by clearing the 
cache  more frequently? (I'm not caching files or included files, so 
I'm  mainly thinking of the variable caches)

We are running this exact same environment in a few locations and 
the  only problem we have with the Witango service hanging seem to

occasionally  hang when a @purgecache was not done and right now i'm 
chalking that  up another problem with caching system but on the 
"loading of the  cache" side of things.  The server hangs not 
directly related to a  @purgecache are few and far between, so not 
much effort has been put  into debugging them.

The code isn't doing any @purgecache calls is it?

Hey everyone-
Anyone out there using Witango 5 connecting to SQL Server 7? One of  
our clients' environment is Windows 2000/SQL Server 7/IIS/Witango 
5,  and we're still having odd issues with threads getting stuck  
seemingly on queries (different ones, not always the same) and then  
hanging the Witango service. Since it's lots of different files, 
even  ones that I've rebuilt in Witango 5, I'm wondering if it's an 
ODBC  issue. Anyone out there using this combination (ODBC Driver 
verison  3.70.x)? Windows and SQL Server both have the latest 
service packs  (issue was there before and after those updates to 
SP4 on both).

Thanks,
Jason
