I'm not so sure.

The use of CLOBs (I had the impression that CLOBs were appropriate, rather than 
BLOBs) means that DB2 eases a lot of the management. By placing the text into 
multiple stream files, you are taking on a significant management task.

As long as there's _always_ only a single stream file, it's no big deal. But 
when the second one is stored...? Generate new file name? Generate thousands of 
file names as new ones get stored? Track the names in a separate SQL table so 
you know what file names are associated with which text strings? Purge obsolete 
files (and associated table entries)? Manage how many are stored in the 
directory? Multiple subdirectories? ...?

A single SQL table with a CLOB column could be significantly easier.
