I like that I can just apply my filter to any application without changing
anything in the application itself.

As far as I know, you can't access datasource connections 'remotely'.

A better solution is to figure out why you have so many objects. GC cycles
increase linearly with the the more memory you allocate. If you allocate
2GB of memory, then it's normal to hav 10-20 second GC cycles. If you're
getting values that are that high (with hotspot) then you need to profile
you
Gerald,
Thank you for your explanation.
But my question was a little bit different. I was wondering why to take care
of removing SBs when there is remote garbage collector which is responsible
for it. But maybe you want to make some special cleanning up or you are
facing another type of problems I
I've had similar symptoms with ATG Dynamo. It usually occurs when the VM
decides to garbage collect. The way we get around this is to have
multiple Dynamo instances each with it's own dedicated VM and CPU. This
makes the user experience more acceptable across all sessions on the
system since th
And from totally out in left field, how about conflicting database
transaction/table locks. I doubt it, because those tend to be indefinite,
but it's a thought anyway! I suspect that the running-out-of-
connections idea is more likely to be correct, though...

I've a problem accessing a pooled datasource from OUTSIDE the web
application. I can access and use the regular datasource, but when I try to
get a connection from the pooled datasource I get null pointer exceptions
from orion's pooled driver. The scenario is this: I have defined a

What is the maximum number of connections that you have configured your
database pool to? Could you be running out of connections? Are you
properly releasing the connections back to the pool, and closing results set
which might not be needed? During the time that the site is "frozen" (as

Q: Could it be a garbage collection related problem? If it's happening at
odd times when heap usage is up, it might be gc collecting old jdbc objects?

I've been working on getting Orion running in a production environment for a
little while now and just when I thought everything was working fine I go to
push to production and something load/volume related is creating massive
slowdowns.
Basically every 250 database accesses or so there is a long

Here is some code that merely gets the connection in a JSP, using the
DataSource.

I totally agree that there would still be an IO operation. I am not sure of
any easy way around this. You could I suppose have a class run (just a
normal class) that checks the file date at some interval. Then if it changes
fire an event that the session beans listen for. when they receive the eve
Try following code in your .jsp file:
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/Oracle");
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM dual");
while( rs.next() ){
Your going to have to use CORBA from what I understand.

I haven't tried solving this problem myself, so am really just guessing.
I wonder if the thing to do is stash your serialized class in JNDI, and
then do a lookup and grab it when your session bean is instantiated?
I'm assuming you need acess to the information in an EJB as opposed to
a servlet; i
Hi,
I am using the latest version of Ant from CVS
(1.4alpha) and I generate a war file using the task. However, this
war file fails to be unpacked by Orion with the following message (that happens
after about 30 seconds) :

It seems the granularity of re-use you describe is at the application or
web-application level. Obviously, such objects must exist internally to
Orion. There may be reasons why they are not public, but I certainly would

Al,
Steps 1 and 2 are already done. But using the serialization class, although
faster than reparsing, is still an io operation.
What I would like is to have the objects member variables of an application
bean, so they would always be available, and in memory. Maybe that is the
trick. Most of th
