Default Slow Open operation (only inside IIS) of database files on a remote Netware Server - 07-13-2006 , 07:51 AM






Hello,

I have the following scenario:

Machine 1: Windows 2003 Server with IIS in a workgroup (No Active
Directory), Web application in ASP, Pervasive SQL Workgroup 8.7, Novell
Netware Client 4.9

Machine 2: Novell Netware 5.0, Pervasive SQL 8.1 Server and Several
database files

The 2003 Server runs a web application in IIS that uses a ActiveX COM
object through ASP, the ActiveX calls btrieve functions and returns
data to the ASP, the data is in the remote Novell Netware with
Pervasive SQL 8.1 server, the files are opened through a UNC path
because inside IIS the mapped drives don't work, and the IIS is using a
normal user instead of the IUSR_MACHINENAME, the user is also created
in Novell with all access to the directory of the database files.

The problem is that a btrieve open operation takes more than 14 seconds
to complete, that problem doesn't occur outside IIS using for example
the wbexec32.exe to open the same database files.

Any thoughts on that is the problem?

Best Regards,

Mike

A few things to try:
1) Try upgrading the engine and client. PSQLv8.1 is pretty old -- I'd
take it all the way to PSQLV8.7.
2) The NetWare Client 4.9 can be flaky -- try scaling it back to 4.8x
and see if that helps.
3) Can you get a network trace of the problem? It could be something
simple like DNS resolution taking a long time...

Hello,

Odly enough i have solved this by making a login through asp to the
Novell Netware with the ActiveX NDAP Controls, and the open times
dropped to milliseconds, is this what i have should done?

I am asking this because i installed a similar scenario and the open
times are fast and i didn't had to make a login in asp to Novell.

I'm puzzled...

Best Regards,

Mike
