Re: AW: Update: Performance Scalability
Hi Tom, I would like to know exactly the diference between ejb-location and pooled-location. ...and other thing...but I thing that Orion team is the only one who can answer me... How does ORion manage the connection pools??? I mean that Orion only let you set the max-number of connections but I want to know how many connection does it create at the begining, the number of connection that it creates when the initial ones are busy, if these extra connections (out of initials) are destroyed after a certain time whithout using them, an so on This is very important because imagine that your application has a lot of clients and inmediatly you start the server you gonna have 200 hundred clients.. in this situation it cuold be great tha the server creates at least 250 connections at start. Now imagine that you have a hot peak of affluence and you run out of connection (250 all busy) you will need more but because the extension of your application, it would be a great idea to create extra connections but in groups of 25, and destroy or not destroy them in a timeout depends on your decision. All this with the security that they will not be over a certain number of connections that you set and could cause a fall in your database. Now imagine the opposite situaion, you have a small application whith perhaps only two clients connected to the DB at the same time, it would be a lose of resource if your server creates 100 connections at start, the best could be to create only 2. And if this connections are busy it would be awfull to create a extra group of 20 connections at the same time because probably youwill only need one or two extra connections. Here you can see how you can take advantage of connection pooling. I'm sure that Orion manages the connection pools eficently but If the problem was the connection pools and weblogic let you set all this values, Have you thought that perhaps your configuration in weblogic is not the best for your applicaction? Repect to the Orion team...It would be very interesting to know something more about how Orion manages connection pooling. THANKS ALL. - David Sierra Fern ndez E.T.S.I.

Re: SSL - 100% CPU
Hello, Yes, we have found a bug related to the 100 % CPU thing. It seems that when a bad certificate was used, IOException's get thrown in the ServerSocket accept() call immediately, which is not the usual behaviour of a ServerSocket. We are now taking care of that problem in a nicer way, and hopefully you should not get that behaviour in 1.1.9 which is available. If you do, please let us know.

Re: UserTransaction.
Hello Rui,
Currently we do not support getting a UserTransaction reference from an
application client (the specification does not say that clients should have
access to it). We will probably implement it in a future release, but it will
then be Orion specific and not portable to every J2EE server. Also, it's usually
not a good choice to do transaction demarcation on the client.
I would recommend doing the transaction demarcation from a session bean. If you
want to, you can see the session bean as a part of your client logically, just
that it's residing on the server, and you can probably put the kind of logic you
want client transaction demarcation for in the session bean (but since I don't
know exactly what you're using it for, I can't say for sure...)

In the EJBs of the Pet Store is coded a (or several) JNDI name(s) (don't know which in this moment). This name must mach to the given name of an "ejb-location" of orions data-source, not to the given name of "location". If accidently this _name_ in the pet store is "location", you should set ejb-location="jdbc/location". If by now the pet store used the "naked location", you should observe significant performance gains. And - what's more - only with the ejb-location transactions can be rolled back properly.

RE: AW: Update: Performance Scalability
That's a good question but I don't know the answer either. I use ejb-location in my code. I'm going to guess that 'pooled-location' can be used via jsp pages or other Java objects that are not participating in Ejb transactions but maybe someone can confirm that. Unfortunately, the one thing lacking with Orion is documentation. There is someone who is starting a documentation site at: http://www.orionsupport.com/ It still has a long way to go and I'm sure it will get there. I know there's a number of tools that come with Orion but I have never seen any docs on this. As for connections, I would like to see 'startup-connections' and 'soft-max' added to the connection pools. Obviously, 'startup-connections' would be the number at startup and 'soft-max' would be the number of connections always maintained in the pool. Then 'max-connections' would be the absolute maximum that the pool would never exceed.

The version I'm using is whatever was available from the web site about a week ago -- orion.jar dated 6-5-2000, v1.xx. Some observations: 1. XML not DOM Level 2 My beans have used XML from the beginning and I'm using xerces xalan. Orion uses parser.jar from Sun which is DOM Level 1 compliant and includes the org.w3.* and org.xml.* packages. This creates a problem when my beans try and utilize methods that are in DOM Level 2 such as Document.normalize() and Node.importNode(). My temporary solution was to remove those classes from the parser.jar file, they're then picked up by xerces.jar which resides in the classpath. IMHO this is a problem in Orion. As far an application is concerned, they should only be able to see the J2EE classes. Somehow the class loader scheme needs to insulate the application from the server classes. In this case XML is not part of the current J2EE spec and I'm hoping they won't add it. I haven't looked at an future specs on J2EE. Eric :-) 2. Performance significantly slower It's not rocket science, but I clocked the elapsed time it takes to complete a round trip from a test client. Using the same code, Orion was at least 2x slower than WL 5.1 and did not scale well when more clients were added. WL 5.1 Orion 1.x One client .4xx.8xx Multiple (3).6xx2.xx I could live with 2x slower but when adding more clients it simply gets worse, much worse.

Re: UserTransaction.
Hello Rui, Ok, since you want it, we'll implement it. It's put up as a feature request, so expect it in about a week. Rui Gil wrote: Hi Karl, Well, you're right, as far as I know the specification doesn't say that this should be implemented, but it doesn't say the opposite either... and this is a common feature around J2EE servers. So I really hope that the Orion team implement this one quickly... I don't understand why the implementation is not going to be portable, aren't we talking about standard interfaces here ? It will not be portable since it's outside the specification of the platform. You're looking somethign up from the environment that the specification isn't saying will be there. That's like relying on System properties that might be there on some platforms, but not on some. You are using a standard interface to access the systerm properties, but they will not always be there. This means that your application will not be "pure J2EE" and work on every J2EE server, but as long as you're ok with that, it's no problem, except for the usual problems of transaction demarcation from the client (network latency making the transactions long, and with many clients, you could get many long transactions going...) Moving your transaction demarcation across the network to the session beans on the server will usually help your application to perform better. Regards, Karl Avedal

Performance Scalability Concern
Actually, there is a simple method to turn it off. From Magnus Stenman: "Remove parser.jar and jaxp.jar from the Orion directory and then start Orion with a -Dxml.parser=xerces switch. This launches Orion using the xerces parser only. I hope it helps." I agree, they have stepped outside the spec on this one but maybe the spec should be changed. How does a container process the ejb-jar.xml file if it can't load a parser? Hopefully, they don't have to write another one just to conform. It's one of those gray areas I think. At least I don't have to 'hack' the jar files and Orion has provided a switch.

RE: Performance Scalability Concern
I understand but if you didn't have a J2EE container how would you resolve it? Once in the CLASSPATH all objects within the same JVM are effected by the order; therefore, the idea of self-contained components break down. They're all subject to the JVM including J2EE implementations. Do you really want to start dynamically loading your own specific classes via reflection? I don't. How many vendors do you know even truly have as close to a full J2EE implementation that Orion has? JBoss is going to rely on plug-ins so now your reliant on multiple vendors and release schedules. Weblogic ($$$) is very very close but they fall down in some areas as well, and IBM well.

When you have a large codebase then pieces of it and the applications may use different non-binary compatible versions and this breaks the component model of J2EE.

Thanks, that solved the class cast exception, but I am not getting anything for
the EntityContext's environment. I get an empty Hashtable back.
I guess a better question would be: To set the principal and credential in the
EntityContext's environment, does that have to go through a SessionBean, or can
any Java Object set it in the JNDI Context?

Subject: EntityContext Environment
I am trying to get the EntityContext's environment . Since Sun deprecated the
getEnvironment() method. I have to use the JNDI interface.
My code looks like this:
try {
InitialContext ic1 = new InitialContext();
InitialContext ic2 = (InitialContext)ic1.lookup("java:comp/env");
Hashtable env = ic2.getEnvironment();
Enumeration keys = env.keys();
while(keys.hasMoreElements()) {
Object key = keys.nextElement();
Object value = env.get(key);
System.err.println(key.toString() + " = " + value.toString());
}
} catch (Exception e) {
}
My problem is that I am getting an Exception
java.lang.ClassCastException: com.evermind.util.r

com.tsis.utils.net.JNDIEnvironment.showEnvironment(JNDIEvironment.java:32)
on the line:
InitialContext ic2 = (InitialContext)ic1.lookup("java:comp/env");
I looked in the orion.jar file and that file is there. Not sure what to make of
this. Does anybody have any idea what is going on??
Re: EntityContext Environment
Hello,
Change
InitialContext ic2 = (InitialContext)ic1.lookup("java:comp/env");
to
Context context = (Context) ic1.lookup("java:comp/env");
and you shouldn't get the error.
InitialContext is the starting context, not all contexts are InitialContexts, that's
why you get a ClassCastException.

Persisting session across restarts

So if I have a handle to an Entity EJB stored in the servlet session, kill the server (ctrl-c, admin shutdown, kill, etc.), run the server again (java -jar orion.jar), then I want those handles and the users' sessions to still work so the users' sessions are still logged in/authenticated.

Make changes without losing session?
Whenever I make a change to one of my servlet source files while a user is in the middle of a session, Orion appears to terminate the session and on subsequent page requests gives the user a ClassCastException (e.g. java.lang.ClassCastException: com.quicksweep.BrowseList at /directory.jsp._jspService(/directory.jsp.java:32) at com.evermind.server.http.EvermindHttpJspPage.service(JAX) ). I assume I must just be doing something stupid with my configuration. In an attempt to keep my configuration relatively simple, I'm just using the default web app setup. I added the following to "global-web-application.xml" : classpath path="c:\qs\sdev\src" / (this is where my servlets and beans are) classpath path="c:\qs\sdev\lib\mysql_comp.jar" / classpath path="c:\qs\sdev\lib\ewin-jdbc\ewin" / I also tried taking out the first classpath entry and putting all my source files in WEB-INF/classes/... Also, I was wondering what the expected behavior is of doing a RESTART or SHUTDOWN-then-startup. Should all the user sessions still be valid when the server comes back up? They aren't for me, currently, but I assume that's caused by the same problem as above. If someone can enlighten me, I'd really appreciate it. Thank you, Brien Voorhees
