RE: Record locking via JDBC

One thing you can do is to lock the record via SQL "select ... for update"

Subject:        Record locking via JDBC

I have a java program that reads and XML document and updates 
4 tables on our iseries via the ToolBox JDBC driver. 

I am having a problem with the program beginning the update 
process, then encountering a record lock after it has already 
updated some fields (it does each field as a separate update 
statement). I would like to be able to lock the record 
that I will be updating in each of the 4 files before 
I update any of them. I do not want to put all of the updates 
in a single transaction as I don't want to roll back the changes 
if there is a failure of one of the updates (which is why the 
program does each field separately).

Is there a way to do this? A "read the manual" response would 
be welcomed especially if you could point out a good starting 
point.

TIA,
