> Hi!
> I'm porting some j2ee web based applications from BEA Web Logic to Tomcat
> 5.5.
> In BEA Web Lobic connection pool it is possible to specify init SQL qurery
> that server runs after connection is created (before first use). It's very
> good for example of national settings in Oracle. For correct czech sorting i
> have to run "setting query":
> ALTER SESSION SET NLS_SORT = XCZECH
> First time i tryed to write interceptor into my application. This interceptor
> runs ALTER SESSION SET NLS_SORT = XCZECH before evey sorted query (SELECT ...
> ORDER BY...), but i had some performance problems. So i starded to work with
> DBCP. I was very wandered about DBCP packages in Tomcat 5.5 and i did not
> find
> sources of naming-factory-dbcp.jar. So i refactored, enhanced and compiled
> full DBCP (with pool and collections). Now i'm a little afraid of some
> library
> conflicts (full DBCP, full Pool and full Collections refactored into tomcat
> packages), but performance is OK and basic tests of my application seems good.
> I added property connectionInitSql for int SQL into BasicDataSource. I had to
> mofify BasicDataSourceFactory for correct setting of this property. Property
> is used in method createConnection() of DriverConnectionFactory to init
> Connection.
> It would be very nice if you will add this init feature into Tomcat DBCP.
> Best regards
