Do you have biDir or uniDir CMR ? Using findAll query on lot of table rows is
not the bets way how to retrive huge data from DB.

Do you check sql statement generated by finder method ? (turn on debug/trace on
plugins.cmp classes) ?
Are you able to catch query plan on your DB ?

1 - 10 clients is OK.
If your SQL queries would not be slow your clients achieve the time response.

How many concurent clients should be serve by the JBoss in 33ms (300 req/sec) ?
What about RAM in JBoss server ?
Did you make some tests of SQL statements that you run inside the WS. Does this
sql statemnts achieving the expected time response ?
We are able to do 500Tx(not easy Tx) per sec in
1.5 Sun JDK is very good in both systems (Linux and Windows)

And what about to use resource reference
| * @ejb.resource-ref
| * res-ref-name = "jdbc/MyDataSource"
| * res-type = "javax.sql.DataSource"
| * res-auth = "Container"
| * res-sharing-scope = "Shareable"
| * @jboss.resource-ref
| *res-ref-name="jdbc/MyDataSource"
Using MBean is the good point but you can write your own CORB-to-EJB proxy
servants and run this servants in separate CORBA server. It is very easy to
write proxy generator which does all the work for you. This solution has one
big advantage:
You can use this scenerio for any J2EE App server. W
Why do you need to spread CMP (CMR) in more than one ejb.jar file ?
Ww have more than 100 CMP/CMR beans in one jar and we did not see any problem.
CMP is always the lowist tier in the project and should be compact for all
applications based on this structure.

This is not problem of JBoss. !!! JBoss is fast as WebLogic or WebSphere.
It should be problem with resolving service. Do you use ip or host name to
connect to your server ?
Dou you use rmi invoker or http invoker ?
Did you trace the request rout (ethereal etc.) ?
Your operation should be

Hi krishnan,
can you specify your test appliaction more ? I think that your test app is
based on CMP because you are CMP Borland expert or i'm wrong ?
I did a few test with BES and JBoss and you are right taht the BES is faster
but in my test it was only 10 or 15 %.

Hi All,
i post this message just as a congratulation to JBoss group for great job in
CMP implementation. I test the same big App (more than 100 EB CMP and CMR, more
than 50 SSB and SFB) with JBoss (3.2.3) and EAS 4.2.2. JBoss was more than
100% faster then Sybase App server.

Hi all,
i have a very simple question:
Is it posible to turn off select statement (findBy PK) in create method of main CMP
bean? This is done only for 1:1 CMR fields. This behavior cause bad performance in our
appliaction where we have to insert dozen of beans.
bean A, B (1:1)

setParameter method a litle bit: I added one more case

Hi Martin,
the best way to keep your data save in the DB is to encryt or decrypt data using DB
engine tools. Sybase SQL Anywhere do this for example.
