SAPDB not comptetive due to neglect of Win32 drivers

It is more fundamental than our personal stability problems with ODBC
driver. OLEDB has been the newer standard for Windows drivers for many
years and SAP never bothered. Now dotNet is over 18 months shipping and
still no interest in a driver.
It isn't just my personal interest, I fear that SAPDB / MaxDB seems to
continue to ignore a huge target - taking on Windows Server users. SAPDB
has equal kernel support for Windows and Unix platforms. SAPDB could be an
ideal product for people migrating from Oracle or SQL Server but still
wanting to stay on Windows Server for the OS (it is not uncommon to have a
company who is willing to switch DB's but not willing to switch OS until
It is for the same reason that I am hopeful SAPDB will have a FreeBSD port.
Most _clients_ are Windows... and SAPDB has done the most to neglect the
drivers on that platform. dotNet is the Microsoft modern architecture
(their Java clone).
I came up with the $5000 figure not because we profit form SAPDB. We do not
resell it. If we did, the forthcoming mySQL license changes would be more a
hot issue with me. $5000 is pretty much the _lease expensive_ option for a
commercial database that supports unlimited users in a web site (DB2, SQL
Anywhere Studio, Microsoft SQL Server 2000, Oracle even more $). And even
that, it is US$5000.00 per processor.
From my perspective, PostgreSQL is the major free competitor to SAPDB /
MaxDB. Alas, they have neglected the Win32 server platform (which they are
addressing a native port (not cygwin) in 7.4).
SAPDB is ahead of PostgreSQL in the native win32 port. But SAPDB is behind
PostgreSQL in FreeBSD/*BSD support + _way behind_ in driver support.
PostgreSQL: ODBC + OleDB + dotNet drivers
Firebird & Interbase: ODBC + OleDB + dotNet drivers
MySQL: ODBC + OleDB + dotNet drivers (multiple choices for dotNet drivers)
SAPDB: ODBC only
Thomas: You acknowledged on Tue 9/24/2002 the socket problems in the SAPDB
Win32 ODBC driver under high concurrency. You DID reproduce that problem.

I know that you have problems at your site with ODBC. However,
the problem does not seem to be easily reproducable since
you never send me some standalone code to reproduce it in
All what you reported (into the list and directly to me)
let me think that the reason for that
is the driver. And I can assure you that I investigated a
considerable amount of time to find the cause for that.
Until now the problem apparently remains, what I regret.
But without being able to reproduce problems, it's not so
easy to find solutions.
I can understand that you might be somewhat frustrated but
I hope you exaggerated a little bit.

It's good to see that some business is growing around
our DB :-)
