I have a doubt on the Concurrency control in Oracle WAS 3.0 As the Webserver is using its Transaction model to provide transaction demarcation, transaction context of client will be stored in the database.
When a client has not commit its transaction, data refered will be locked.
If there is another client needs to process the same data, it has to wait
for the earlier client to release the lock. so the later client has to wait for the commit to take place or the time out session on the earlier client. Is that true ?

thanks in advance.
