Shep, you're using DCOracle2 1.3 or higher, right?  DCOracle2 1.2 
release is busted with respect to LOB objects, which DCOracleStorage 
uses (all LOBS get marked as being temporary, and if they're actually 
REAL lobs, the temporary flag is never cleared, making all reads return 
0 length).

I think this is probably what is griefing you.
