Hi!
I have a MDB reading a constant stream of messages from a Queue. The MDB is
storing the messages through two CMP entity bean with a CMR. The data written to the database will be read but never updated. I would like to optimize the process from MDB to database.
When I look at the use of database connections, it seems that only one is in
use. I guess this has something to do with my use of transaction attributes.
I use the default transaction settings on Oracle which I believe is
READ_COMMITED. The CMP has "Required" transaction setting. The MDB uses
transaction-type="Container" and "Required".
Primary keys are issued by a session bean that requests blocks of keys from an
entity bean. This bean uses "RequiresNew" and row locking.
What would be the best settings to tweak?
Thanks in advance!
