Summary: I'd like to run init SQL after JDBC Connection creation
in DBCP
Product: Tomcat 5
Version: 5.5.9
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Unknown
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: jmelichna@gitus.cz
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 ini 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
set 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 had to refactor, change and compile
full DBCP and now i'm afraid of some library conflicts (full DBCP, full Pool
and full Collections refactored into tomcat packages), but performance is OK
and 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
Jiri Melichna
