Re: Orion crashed under load test
I received the following question: - Original Message - From: "Tony Cleverley" <[EMAIL PROTECTED]> > What tools were you using to load test Orion and are > they in the public domain? Well, we used our own showcase application (which we actually have put into the public domain (cf. http://www.livis.de/projects/livingtalks). However, the Orion version of it (version 1.1a rather than v1.1) is not on this server. If there is interest for it, I may release it, maybe also as a showcase application for orion-support. It is a conference management system with EJB and CMP running on real conference data (http://www.netobjectdays.org). We simulated traffic with a couple of scripts containing lynx commands with multiple processes and running on multiple boxes. As a side note: v1.1 (Sun's RI with Cloudscape) needs 210 minutes for the import of data in a single transaction while v1.1a (Orion with Firebird) needs 0.75 minutes... Must be a bug in Cloudscape ?!

Title: RE: Orion crashed under load test Hi, Thanks for your help, I changed my JDK to sun's JDK 1.3 and orion did not crashed, actually it worked just great !

Re: Orion crashed under load test
IMHO you should dump the IBM jdk and get the latest sun 1.3.1 beta. IBM crashes frequently with orion here. Sun 1.3.1 beta has not crashed a single time since we started testing it for development 2 weeks ago. btw. we use sun1.3.01 in production and have not had major problems except for some crashes during application redeployment.

Re: Orion crashed under load test
Orion crashed under load testHi Eyal, we've put Orion 1.4.7 here under a 1-cpu stress test (80 concurrent requests of type JSP(1)->EJB(1)->EJB(n)->DB(n)) and it was ok. Win2k and JDK1.3. It reached a throughput of 200 transactions per second (466 MHz Celeron with Firebird/Interbase). Latency then went up to about 4 seconds per transaction. It is reported that JBuilder debugging is unstable with IBM JDK under Linux but not Sun's JDK. Therefore, I speculate that you crosscheck with Sun's JDK. Bye, Falk - Original Message - From: Eyal Litman (Kamoon IL) I load tested orion under linux red hat 7 and IBM 1.3 JDK. Orion crashed after few minutes of "easy" load. Does anybody had some similar problems ? Could IBM 1.3 JDK could be the cause ? Thanks in advance, Eyal Litman Server Side Team, Kamoon Ltd.
