Subject Re: Updates to OEJB 2.2 and TranQL 1.4
Date Mon, 20 Nov 2006 17:26:10 GMT

Basically it allows one to specify select-for-update to delegate  
locking to the db.  It does not explicitly allow one to set isolation  
level on each call though.

I'm modifying the Rar for db2  to allow the specification of a  
default isolation level so one is not tied to RS for DB2.
