You can even go for caching products like coherence tangasol which can
perform better in a clustered server environment. We have done a load
testing with CMP read only entity beans. It has a performance bottleneck
when number of user's increases. Going for static objects is also one
option.

Rgiri-

Depending on what framework you are using for persistence, I would look
@ what it supports. E.g. We use hibernate & have set up the level 2
cache appropriately for our read-only tables. Weblogic allows you to
configure CMP beans to be read-only and if set will cache them in the
app server tier. I'm sure other persistence frameworks have equivalent
solutions to this problem.

Hello,

I would like to know what will be a good way to implement the
following:

We have many read only tables in the database. I was thinking
rather than doing a select all from the table all the time, we would
like to keep the collection of objects in memory to reduce the database
traffic. The SQLs for this is pretty much SELECT * FROM TABLENAME. No
filtering is present. And this collection of objects is referenced too
many times.

Any related articles, pointer will help us.

Thanks,

Rgiri.
