blob and query heap memory

When I try to insert a large blob (10 megs) into a db2 database using JDBC, I get an error about the query heap not having enough memory. When I increase the query heap size to more than 10 megs, the query executes fine.
Interestingly enough, the same blob inserts fine using a CPM.
If I guess a number too low, I could wind up with a large blob that crashes at runtime. Is there any way to stream the byte[] passed so that JDBC doesn't try to load the whole thing in memory at once?
