Hi,
I have small design question. I need an cron service in J2EE environment.
I've seen the scheduling service from JBoss, but I have to do some jobs
like cron job each day at the same time. What will be the best solution
with JBoss?
Regards,
Rafal
What is a good estimation model for determining the
prepared statement cache size ?
About how much memory (or other overhead
considerations) would anyone estimate a cached
prepared statement will consume ?
Thanks.

Hi,
What is the correct pool size for a database of more
than 3 entries ?
I will access about 6000 of the EJBs every 10 seconds,
read/write, commit-option set to A (exclusive table
access)
thanks for the info,
ionel

Do You
Are your ejbs expensive to construct?
The pool isn't very significant if they are not.
Under option A instances are not returned to the pool
until they are removed from cache.
Only the home invocations will perform any significant
pooling. So how many of those run concurrently at peak?
Regards,
No, at the moment OL is condfigured per entity.

No, it does not depend on the container configuration anymore (AFAIR
since 3.2.2). You could configure OL with pessimistic locking. It does
not make sense unless in a cluster.

Yeah, I already did a look at it.

EJBs are made of about 10 fields, mostly double and
Date (say 3 dates, 7 doubles)
8 finders (home calls) are called concurrently every
10 seconds to retrieve a collection of EJBs which are
then updated (4 fields out of the 10)
By now, one finder should return a collection of 3800

This is an approach I also tried and it looks very promissing.

By expensive to construct, I meant it allocates resources
not the new MyBean() operation. ;-)

This is the same feeling I have about Lomboz.
But it has a lot of good

If this still takes too long, look at breaking up the components in
the .ear. Either into smaller .ears, or into individual components

to re-deploy the components that have changed.

So, will this put JBoss on knees or is it ok ?
What could be the best pool size and cache size ? (if
it has any impact over performances)

There is a limit on open statements I believe in the DB. So that number
/ num connections you need.

Pooling is insignifcant. I'd worry about optimizing
the query/cmp loadng that does 6000 rows.
