Hi,

 

At least OCI allows LOB buffering (search for LOB buffer= ing 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 a= nd inserts are done only during flush operation.

 

JDBC might have something similar...<= /o:p>

Hi, everyone!=

 

      &n= bsp;     Have a client who’s having an intermittent problem while inserting file_blobs into the database.

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

 

Asked them to put in JDBC trace but th= ey say they’re too busy to restart app.

 

      &n= bsp;     I was wondering what kind of tuning could be done in JBDC?

 

 

      &n= bsp;     Thanks

      &n= bsp;     Larry Wolfson
