Subject: GDSF Configuration

I have a couple of questions about the GDSF config file.
 
1. The GDSF documentation states that "more than one DBMS can be
specified in a [GDSF] configuration file".
 
Does this imply that one client can request a GDSF create a GDS to query
one database (say Oracle) and another client can use the same GDSF to
create another GDS to query another database (say MySQL)?
 
2. I have three databases specified in my GDSF configuration file. It
appears when I run the client, OGSA-DAI attempts to use only the first
specified DBMS in the GDSF file and ignores the others.
 
For instance, in the included GDSF config file, I have configured
Oracle, MySQL and Xindice dbs. If my client performs an Oracle query
the results are returned ok. If I then use my client to issue a Mysql
query, OGSA-DAI tries to use the Oracle database. When I swap the
configuration around such that the Mysql database is configured first,
results are returned for the Mysql query, but the Oracle query fails as
it tries to use the MySQL db.
Is this expected behaviour?
 
Thanks
 
Brian
