Can anyone please help us with this huge problem were having?

Using VDF 9.1 (and other versions, i.e. 5 etc) we are having SEVERE SLOW
performance with our applications as a pose to when we were using Netware 5
etc. Is this a known problem or merely an easy server option not selected?

We have to DISABLE FILE CACHING & ENABLE FILE COMMIT on the Novell 4.9 SP2
Client to avoid data *corruption*.



Any help would be MOST welcome!

I am running very will with Novell Client 4.90 SP2 on netware 6.0 and at
one time we were running VDF9 and VDF10 (and DF 3.2).... we have since
upgraded all VDF users to 10.1. All seems well.

Hi Lee,
The #1 Reason for slow performance is the virus protection system (you
probably have Norton).

The solution for slow processing is to go into norton and tell it to exclude
checking *.dat, *.hdr, *.k* and *.vld.

VDF and Netware should scream.

PS: I have been watching this NG for a long time and the number 2 reason
for slowdowns is a failure to upgrade netware for the latest patches.

The Data Corruption issue is another one I think I can help with.

Simply insert this code into your program once:
set_attribute DF_HIGH_DATA_INTEGRITY to DFTrue

This will probably solve the data and index corruption alone. It is also
known to slightly slow down processing so I recommend you take this as a
second step. Here, you give up 10% on the speed and gain control over data
corruption.
Regards,
Peter Donovan
PS: Are you running with TTS enabled? This would further guard your
transactions so that if a power failure happened but you had a UPS on the
server, it would rollback all incomplete transactions for you without
corruption. You would set your data tables to server_atomic here and get
quasi client-server ability.

Thanks Guys for the comments!
We've tried all of those and still having issues, however actuall
applications seem ok, BUT when we run a Crystal Report accessing a dat file
things are so slow...I mean really bad, any ideas???

Thanks
Lee

Lee,

Just excluding the *.dat, *.hdr does not completely do the trick. At each workstation using
Norton/Symantec in the Configure/File system Auto-Protect, uncheck the Drive Type: Network so that
network drives are not checked. The servers should be protected with the server version of Symantec
A/V.

Lee,

Elsewhere in the newsgroups you report you are using Crystal 7. This version
uses the CK 1.0 which cannot do a jump into index which makes selections
slow. But there is IMHO no relationship between this and VDF9.1 / Netware
6.5. It is just slow on any environment.

Crystal 7 was superceded by 8,9,10 and now 11. The DataFlex Connectivity Kit
for Crystal Reports is not yet available for Crystal 11 so you need to buy a
Crystal 10 version with new CK.
