Re: DB/400 Java and C++ Stored Procedures

Hi
I recommend you to read Java and WebSphere Performance on iSeries Servers
Redbook (SG24-6256-00).  Chapter 2 The Java Execution Environment on
iSeries has a really good explanation in what you want to now.  It is
available on ibm.com/redbooks.

        Subject:        DB/400 Java and C++ Stored Procedures


All,

Does anybody know how memory management works when you write a Java or C++
based stored procedure for DB/2 on the AS/400? Or a bit more specific,

1. Does DB/2 have one JVM in which all stored procedures are running?
2. Where would you measure if you wanted to monitor how much memory is
used
by the a Java stored procedures or how much CPU is used?
3. Where does the memory get allocated if you write a C++ stored
procedure?
4. If you have a C++ stored procedure that "leaks" memory where would it
leak? So if you do not de-allocate memory that you allocated with new
would
DB/2 force a release of some kind?

Thanks,
Etienne
