Using SQL Server 2000 XA Driver

Question

first off, I am a newbie
I installed Workshop 8.1, and setup a Domain to use by creating a Weblogic Domain
and then extending it with a Workshop extension.
I want to use it to connect to a SQL Server 2000 backend (I am imitating the Java
Control tutorials without using the Tutorial part to see what problems I encounter).
I want to used the 4xa driver, but none of them work, although if I try to use
the non-xa driver it is fine.
I remember reading the Workshop can only have one non-xa driver, and that it also
must use the cgDatasource via pointbase.
I would be very happy to use the s2k 4xa driver, but when I try it with an XA
in weblogic I always get "no suitable driver found", regardless of whether it
is weblogics, data-directs, j-net-directs, etc. This happens even if it is the
only pool, so I know it is not connected to pointbase.
I even ran the osql command to set my sql server up for stored procedure support.
For now what I have done is switched the cgPool over to an xa driver, and have
the sql as a non-xa (which works fine).
Any ideas?
thanks!

Matt,
Then lesson learnt is a good. Always use the console to modify services on
an existing domain.

thanks for the suggestion!
What I ended up doing was playing around and I determined what I think Iwas doing
that was causing the problem. I was using the Weblogic ConfigurationWizard to
change the JDBC pools and test them. When they did not work there Icancelled
it out.
I think what this did was change the pointbase location in thepointbase.ini in
my server to go to the %bea_home%\common\eval\pointbase. Since theworkshop db
was located in my server dir, and not that one, it was throwing an error.
I got around it by copying back the old config.xml, making some changesthere
and also to the pointbase.ini, and also launching the pointbase manuallyfrom
my server dir when configuring it.
So I have learned my lesson, use the console, not the configurationwizard, after
initial setup. If I had the time I would try to recreate it so I could letBEA
know, but I am just happy that it is working...
thanks again for your help!

Matt,
We did have some pointbase issues in v1, one workaround is to create
a
backup of the pointbase files, after an install, and then unzip them,
if a
crash occurs.
Hope this helps.
Thanks

thanks, I guess I assumed that because the type 4 driver worked, thetype
4xa should,
and have the files already included via the weblogic.jar. oops.
I added the wlsqlserver.jar, wlutil.jar, and wl.base.jar to my
classpath.
Now
it appears to work... yeah!
Unfortunately I have encountered a problem that has happened to meat
least three
times. The "workshop" db in pointbase is gone. The only solution Iknow of
at
this point is to uninstall and reinstall. I can not laundh the
piontbase
console
because it requires the db "workshop", or at least appears to - acatch-22.
I also can't simply reinstall BEA over the top because it will notlet me,
and
I am not sure what part to uninstall, reinstall to get that db back,short
of
uninstalling/reinstalling the whole thing. Since this has happenedto me
three
times (I am a master at breaking things - I have also wiped out theconfig.xml
through extending the domain a couple of times), I should probablystart
experimenting
since I suspect that I will unfortunately do this again.
Thanks for your help, it appears that the classpath inclusion of thosefiles might
have been exactly what was needed for the 4xa to work!

Hello Matt,
A driver being listed in the connection pool drop down, doesn't
necessarily
mean that the driver is on the classpath.
Can you try placing the driver jar in the server classpath ?
The requirement of one non xa driver is due to the fact that JMS
cannot
work
with an XA data source.
Hope this helps.
