Donna, I am not sure what you are trying to do here, but I hazard to say there is not one single member of this interest group that is interested in your product at $35,000 per cpu. Orion is $1500 per server, and most of us have already created our own enterprise portal services for Orion. Good luck on the Weblogic interest listbut you have struck out on the Orion interest list.

RE: jdbc performance Orion vs. WL
Egor,
Did you use the ejb-location (this is the best)? Also, did you use the
latest 9i jdbc drivers from Oracle? You need to repeat the test with
updating and inserting. Also, create several connections at once to use the
pooling feature.
Drop the stuff about Metadata...not very useful or very real world...and
known to be slow.
I would also drop the i/o, not necessary for this type of test.

Subject: jdbc performance Orion vs. WL
Hi all,
decided to find out who is the fastest when working with DB using jdbc. I
wrote a simple servlet that does the following:
1) acquires connection from the App. Server's JNDI tree and selects 7000
records from an Oracle table.
2) acquires connection using DriverManager (OracleDriver) and selects 7000
records from the same table.
The results are
1) WL ~4000 ms vs. Orion ~7000 ms
2) WL ~4000 ms vs. Orion ~6600 ms
I agree that WL outperforms Orion because it is using its own DB Driver. But
why even standard OracleDriver on Orion is working ~3 sec slower than on
Weblogic 6.1?
May be it is possible to tune Orion so that it could outperform WL when
using jdbc?

RE: security-constraint
Thank you very much. From: The elephantwalker [EMAIL PROTECTED] Reply-To: Orion-Interest [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Subject: RE: security-constraint Date: Tue, 23 Oct 2001 11:37:34 -0700 Carlos, You can change these bits in the orion-web.xml. Also, there should be no need to change the security constraints, since the web.xml uses roles, and orion-web.xml uses groups. Why the difference? Well Karl and Magnus were smart enough to recognize that web modules and ejb modules would be written once, and deployed under many different enterprise applications. But each of these modules would have their own role names for security-constraints. The hard bit is how to re-use these components without rewritting the web.xml. Groups saved the day. So the usermanager (or the jndi access to the roleManager) uses Groups to control access. Normally this is transparant to the developer, since most groups have the same name as the role's in your web.xml or ejb-jar.xml. But when you don't have the same names, you can use group/role mapping in your orion-web.xml file to tell orion which roles in the web.xml file map to which groups used by the usermanager. roleManager has some great methods for managing your groups, as do the usermanager's. Use these methods to mangle your groups and users.

But when I submit a form from a UTF-8 encoded jsp, the parameter data doesn't reconvert this data and store this in the DDBB wrong. I test this with the same JSP in other App Server (Silverstream) and the conversion is automatic. What's wrong, Orion or SilverStream?

Does anyone have any experience with this problem? The error message is unfortunately too nondescriptive, a stack trace might have helped a lot here. This has never worked for us with earlier Orion versions either, so it's not a 1.5.3 thing. Yours, Christian.

I would expect the old API to remain though. If the old method doesn't

I'm interested in what you're saying here? re: your benchmarking; another poster also gave thoughts to configure a connection pool, data-sources.xml, and set min connections to be a reasonable number. - To better stress the container vs just see DB performance or JDBC driver memory thrashing on the result set performance, why not have a test fixture that hit your servlet with 100 simultaneous requests.I think this is where WLS will be much heavier. WLS would also be at more of a disadvantage in EJB, especially Entity, performance. I believe this test is more of a JDBC / DB performance measure and the 7 sec is due to the 8i thin driver.Lets see if anyone gives perf comparisons between 9i thick vs thin?? Anybody have subjective comparison between 8i thick/thin VS 9i thick/thin drivers?? How about useful new features in the 9i thick/thin drivers? Thanks, curt

Running Orion as Win 2000 services ???
Hellu, Some time ago I got the advise to use JNT to run Orion as a service. I finally got to use it and have some problems with it. I got JNT to start Orion, but the applications aren't deployed, neither does any web application work. I used to following command to install Orion as a service: --- C:\jnt "/InstallAsService:Orion" "/SDC:\ProgramFiles\Orion"-jar orion.jar --- I did also put the path C:\Program Files\Orion in my enivorment PATH variable. I also added the server.xml config file, which also didn't work: --- C:\jnt "/InstallAsService:Orion" "/SDC:\ProgramFiles\Orion" -jar orion.jar -config "C:\Program Files\Orion\config\server.xml" --- (I tried some moresimilair possibilities) In the server.log and global-application.log there do appear entries that the server/default web site is started, but nothing works (from the command line it does). I think that it doesn't find the config files, like the server.xml such that orion isn't correctly initialized. What am I doing wrong ?? The problem I am also having is that I don't know how I can see what Orion does. That is, in Linux and from the Windows command line, I start Orion with "orion.jar log/out.log", but how do I do this with JNT ?? I tried something but it doesn't work. The only thing I succeeded is that JNT did put his output in the out.log !!! Please some help ? Eddie

1) acquires connection from the App. Server's JNDI tree and selects 7000

The results are

2) WL ~4000 ms vs. Orion ~6600 ms
I agree that WL outperforms Orion because it is using its own DB Driver.
But why even standard OracleDriver on Orion is working ~3 sec slower than on
Weblogic 6.1?
May be it is possible to tune Orion so that it could outperform WL when
using jdbc?

Eddie, You may gain some mileage from this article: http://kb.atlassian.com/content/orionsupport/articles/orserv.html Also, you can specify a log file for Orion by specifying parameters: java -jar orion.jar -out file -err file I would suspect that Orion is finding your server.xml file, or you wouldn't end up with anything in the log files at all.

I think that it doesn't find the config files, like the server.xml such that orion isn't correctly initialized. What am I doing wrong ?? The problem I am also having is that I don't know how I can see what Orion does. That is, in Linux and from the Windows command line, I start Orion with orion.jar log/out.log, but how do I do this with JNT ?? I tried something but it doesn't work. The only thing I succeeded is that JNT did put his output in the out.log !!! Please some help ? Eddie
RE: SQL monitoring
A previous poster announced this tool and it works -- snoops the JDBC wire as a proxy -- There is a free tool at http://www.provision6.com that intercepts and logs all database statements of any application that uses JDBC. This is particularly useful, for example, for monitoring the SQL generated by entity beans. There are no code changes required to your application, and setup is very easy. There are explicit instructions for installing under Orion. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Alberto Vilches Sent: Wednesday, October 24, 2001 10:18 AM To: Orion-Interest Subject: SQL monitoring Hello Orion-Interest, Anybody knows how to force Orion to show to console all the sql generated by the EJB? Thanks. -- Best regards, Alberto mailto:[EMAIL PROTECTED]
Newbie RMI questions...
Hi, What do I have to do in order to deploy a standard RMI application on Orion? I have looked through the orion documentation and have seen nothing to tell me how to do this. There is some kind of RMI app in the demo directory, but it seems to show only the very beginning stages of a client connecting to a Remote Object. In fact it really only get an InitialContext. It never actually gets a reference to a remote object. Where can I find information on what I have to set up inside the container (where the classes go, modifications to XML config files, etc)? Coundn't seem to find anything on orionsupport either. Thx, Ross.
Poolman under Orion not working
Hi all, Well, I have read some messages that indicate problems running Poolman under Tomcat 4. But here I am having problems running Poolman under Orion. I have a Struts application and I was using the connection pooling from Struts, but now I am changing it to Poolman. But the problem I am getting is that when executing the application, Orion throws the following error: [10/24/01-12:33 PM] GeneralDAO database = 2[10/24/01-12:33 PM] - Getting connection from pool...[10/24/01-12:33 PM] useCount= ConnectionPool: Creating instance...org.apache.xerces.parsers.SAXParserjava.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParserjava.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.xml.sax.helpers.ParserFactory.makeParser(ParserFactory.java:124) at com.codestudio.management.PoolManConfiguration.parseXML(PoolManConfiguration.java:112) at com.codestudio.management.PoolManConfiguration.loadConfiguration(PoolManConfiguration.java:75) at com.codestudio.management.PoolManBootstrap.init(PoolManBootstrap.java:61) at com.codestudio.util.SQLManager.assertLoaded(SQLManager.java:109) at com.codestudio.util.SQLManager.getPoolByJNDIName(SQLManager.java:129) at com.codestudio.sql.PoolMan.findDataSource(PoolMan.java:116) So it looks like it can't find the parser. Well, I just played with different locations and nothing works. - I put the xerces.jar in the WEB-INF\lib directory (where struts.jar and poolman.jar are) - I replaced the xerces.jar that comes with orion and nothing seems to work. Does anybody have any ideas? Thanks -emilio
-secure option
Guys, I am perplexed, what does the -secure option really do when using it as part of the command line to start up Orion ?? If I run my app without it the thing works when I apply it, it's bitching that it can't load certain files... Any hints ??? Thanks, Bruno R. Baloi Lead Software Architect PlateSpin Inc.
Re: Poolman under Orion not working
Make sure you're using the latest version of poolman, or even the CVS version. The JMX management it uses has very screwy (basically, non-functional outside of tomcat's broken classloader) classloading. Also try and run it in non-JMX mode. The latest version does not require xerces and works with JAXP as far as I know (I submitted a patch for that). On the other hand, if you're using Orion, why not use Orion's connection pooling and save yourself from all this pain?
