Hey, Tanel, thanks for feedback.    I'd think there'd be something like that.

I had another client saying a query took 5 ½ minutes.  On the server it 
consistently ran in 20 seconds.  I told him we could eliminate all the database 
time and it would still take more than 5 minutes.  He said he could tweak the 
app server and never came back with that issue.

 

Also, I got another reply, from Nick Goodman, suggesting they look at p6spy.  
The web page there suggested it could identify DB bottlenecks.

Hi,

 

At least OCI allows LOB buffering (search for LOB buffering subsystem) and also 
LOB update bundling, so you can create several LOBs in your application and 
flush these to database later on. Actual network transfer and inserts are done 
only during flush operation.

 

JDBC might have something similar...

 

Tanel.

        Hi, everyone!

         

                    Have a client who's having an intermittent problem while 
inserting file_blobs into the database.

        The insert appears to be taking no time at all, but they're complaining 
about 7 second (or more) response time to app server.

         

        Asked them to put in JDBC trace but they say they're too busy to 
restart app.

         

                    I was wondering what kind of tuning could be done in JBDC?

         

         

                    Thanks

                    Larry Wolfson
