Hi Guys, I am having a problem with v1.5.4 of Orion. In stack traces it displays the line number everywhere except for the EJB's! I know it used to work, any ideas on what to look for?
Transactions and OTS
Has anyone every successfully integrated orion with a 3rd party OTS, or have any idea on how to go about it?

Using a list-mapping with orion and using a vector to store the mapping works if you add elements to the vector using .add, however when using .addElement orion will not store the vector. Wierd or am I missing something? w
Orion not honouring transient attribute?
Is anyone having a similar problem? Orion not honouring the transient attribute in a session bean? IIRC the spec says that attributes with the transient modifier do not get serialized.

Re: Orion Performance Tuning
Enable the undocumented option: -Xconcurrentio You will find that with a large number of simultaneous connections you will gain a large performance increase. (The sun site claim up to 40%, but I have only found a 20-30% depending on the app). Read http://java.sun.com/docs/hotspot/VMOptions.html and http://java.sun.com/docs/hotspot/PerformanceFAQ.html and http://java.sun.com/docs/hotspot/gc/index.html for a good overview.

Sfeir wrote: Hello all, I've gone through and read most of the information posted from this list about improving the performance of Orion, and increasing the number of threads Orion uses to improve its overall performance under load. What I've been able to do so far, and it's helped a lot, is: 1- Added the -Xms and -Xmx switches to make sure Orion starts and uses more memory, they're set at 100MB and 300MB respectively, and Orion uses 175MB as soon as I start it up, and doesn't seem to grow past 177MB as the day goes one and it gets used. 2- I added the -server switch in front of the java command so we make sure we use the Server version of the HotSpot VM. (Boy does this thing pick up speed when using the -server switch!) Is there anything else that can be done, short of clustering, to further increase Orion's performance? My main objective is to make sure we don't get any more weird hangs and long wait times in Orion for no apparent reason. Perhaps increasing the number of threads Orion uses? I can't seem to find any definite answer on that. Our servlet seems to be fine, but sometimes when clicking through a test web site, one url request seemed to just sit there and hang, as if Orion was dead, but I could click and request a different URL and get immediate response. So I assumed it was threads in Orion which were not being managed properly. After making reading the posts to the list and making the the 2 changes above, the problem seemed to have gone away for the most part, except it still happens from time to time in Netscape, IE doesn't seem to have this problem. I can quit Netscape and go back in and the problem is gone for a while. There is no specific time frame for it to happen. It does happen consistently when I click, then stop for about 30-60 seconds, then click again or reload, and it just sits there and waits for the world to come to an end of something. Very bizarre. Any ideas you may have would be of great help. Thanks R Robert S.

I went back and retraced my steps to try to figure this out. I have
a jar inside my ear file that contains an application-client.xml, so
I wondered if that might be causing some kind of infinite loop in
Orion. Copying this jar into Orion's lib directory fixed the
problem. Don't quite know why, but then again, this whole experience
with Orion is turning into one big exercise in trial and error. :(

Re: How do you make JDBC and EJB in same Transaction?
Hi, I have the following in the same method inside a session bean 1 - Get a datasource using the EJB Datasource lookup This is the correct way to do it. Are your ejb's using the EJB Datasource lookup? Check in you orion-ejb.xml What is happening is that the JDBC call is not using the same transaction as the Entity bean and this is causing a deadlock. The Entity bean call is waiting on the JDBC statements to be commited. But these statements will not be commited until the entity bean finishes the delete. I do something similar. I have an session bean that 'Requires' a transaction, and my EJB's are set to 'Supports'. Within that transaction, I do an insert using jdbc, I stuff around with some entity beans, and then I stuff around with the jdbc connection some more. What's even cooler is in another method I process some credit cards, and if this fails we throw the appropriate exception. Effectively the whole transaction gets rolled back. I thought that since both session bean and entity bean are declared as REQUIRE for transaction in the ejb-jar.xml that they would automatically be inside the same transaction. That's correct, so it should work. Just double check that your EJB's and the JDBC are using the same datasource. Is this a bug or is there something that I am missing? Good luck :) Eduardo -- Adam Cassar Technical Development Manager ___ NetRegistry http://www.netregistry.au.com Tel: +61 2 9641 8609 | Fax: +61 2 9699 6088 PO Box 270 Broadway NSW 2007 Australia

Re: Wierd Servlet to EJB RMI problem
I thought the same as well. I was supprised however that when making an rmi call between two different machines, the standard .equals works, however when used within a servlet it doesn't. I (incorrectly)imagined that as the ejb container and the servlet are in the same process that the equals method would work for sure. However I found the opposite to be true. On Tue, Jan 16, 2001 at 10:55:30AM -0700, Nick Newman wrote: Hi, It may be because of the way that the .equals() method is written for your class. For example, the Object class itself says that two objects are equal only if they are the SAME object. After they are passed BY VALUE (i.e. through serialization) to a session bean they can no longer be the same object (even if they were initially) and so will always be "not equal". For your particular class it might make sense to write a more relevant .equals() method.

Value Objects and Entity References
'lo all, I am enquiring about peoples experiences with value/detail objects and entity references. Some of the entity beans that I have are persisting entity beans (ie their pk's - 1 to 1 relationships). If I have a detail object with the entity bean as a attribute, when returning the detail object to the client, I only get null. I take it this is because an entity bean is not serializable. Is the best solution to return a handle and get the detail object to look it up? How are other people on this list handling this?

In addition every test run was slower than the one before it - from my notes when run 3 times each run took twice as long as the one before. The same tests took the same time every run when using Hypersonic or Sybase. This was several months ago, so perhaps it's been fixed. We deleted postgres and moved on...

There are several solutions, but the easiest is to choose: 1 - You want Orion to listen to port 80 (the standard http port) and so you must launch it on a root prompt 2 - You don't mind if Orion does not listen to other port (say, for instance, 8080), but you want to launch it from an ordinary user account. In this case, you must edit the orion_path/config/default-web-site.xml and on the web-site ... tag, change the port from port="80" to port="8080". In theory either one of these solutions, will make the permission denied error go away Best Regards, Fábio Thanks. That explains the error. However, my problem was not that I could't start Orion. I have run it as root until now. I just thought that it might be good, for security reasons, to create a user with less priviliges than root, to run Orion. /Thanks, Mattias -- Adam Cassar Senior Web Developer ___ NetRegistry http://www.netregistry.au.com Tel: +61 2 9699 6099 | Fax: +61 2 9699 6088 PO Box 270 Broadway NSW 2007 Australia Earl Marwil SCIENTECH, Inc. 1690 International Way Idaho Falls, ID 83402 208.525.3717 -- Adam Cassar Senior Web Developer ___ NetRegistry http://www.netregistry.au.com Tel: +61 2 9699 6099 | Fax: +61 2 9699 6088 PO Box 270 Broadway NSW 2007 Australia
