As an aside, Oracle doesn't appear to support 10g's original release (10.0) anymore - and 10.1 extended support ended this past January. You can see this in the pdf file located at the bottom of http://www.oracle.com/us/support/lifetime-support/index.html - the link "Lifetime Support Policy: Oracle Technology Products". So it appears they don't even support 10.0 and probably haven't for a while. 10.0 isn't even on their support matrix chart; only 10.1 and 10.2 (in the 10g family) is listed.
This is relevent because, as per:
http://docs.oracle.com/cd/E11882_01/java.112/e16548/oralob.htm#CHDGEIHF
it says:
"The SetBigStringTryClob connection property of Oracle Database 10g Release 1 (10.1) is no longer used or needed"
so this means all their supported 10g releases don't need it.
