I used Interbase about four years ago in a production environment. It used to be a commercial product distributed by Inprise(Borland at the time) before they open sourced it. It is a very good relational database product. It has most of the features you would expect from a commercial product. The only negative that I have against Interbase, is it's lack of clustering support. It has what they refer to as a shadow that should the machine go down, you can get a second server up and running right away. It has a JDBC driver called InterClient. I have had success with this driver except for one quirk. Everynight at midnight, the InterClient service would error and stop receiving requests. they might have fixed this problem with their latest version. I don't have any info on online back ups. My experience has been with the Windows NT environment. Interbase has been cross platform for many years though. Another thing to consider in the Linux environment, is a journaling file system such as ReiserFS. I am not sure what would happen to your database file if the power suddenly went out or the computer shut down unexpectedly while the database was writing to the file. -Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jim Archer Sent: Friday, October 27, 2000 11:26 AM To: Orion-Interest Cc: Jonas Larsson Subject: Anyone using Interbase in production? Does anyone here have any experience with Interbase in a production environment? We are trying to decide which database to deploy in production. Since we are a very low budget operation, we are looking at Open Source, but somehow missed this one. Our most important requirements are stability, transaction support, a solid JDBC driver (for use with an EJB server) and online backup capability. Any experiences people can offer would be appreciated, especially in a Linux environment. Thanks!

Hi there, I know that the question has been discussed here before, but I'm still a little confused about using MYSQL together with Orion. I've just downloaded mysql (version 3.23.22 beta) and the manual announces that mysql is now supporting transactions. If I understood it correctly, that would mean, that it should be possible to use mysql with entity beans. Am I right ?? What's confusing to me is the fact, that I only find news in mailing-list, that mysql is not supporting transactions. So I don't really now, if I can use mysql for entity beans. If not, which database would you suggest ?? It should work on NT and not be the most expensive one as I use it 'only' for writing my Master's Thesis.

load testing tools/procedures
hi, what are people out there using for load testing when they've finished a web-application? the (affordable) solutions I can think of is JMeter (java.apache.org) or simulating user sessions by coding tests with a package like HttpUnit. I'm particularly interested in testing applications which use sessions and need the simulation of real users (i.e. log in - view catalog - modify shopping basket - submit order - logout kind of stuff). any thoughts on this, anyone? regards, robert (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

Re: rumors
or, as has happened to my company, another entity purchases orion, essentially to shelve the code and remove a competitor. the product i and my team have worked very hard on for these past months is now effectively dead. it would be sad to see the same happen to orion, but when business people get involved, they do not care about technical elegance or excellence -- only money. --bradley mclain (formerly of usmoving.com) --- Karl Avedal [EMAIL PROTECTED] wrote: Hello Keith, Keith Kwiatek wrote: Probably not... but you know sooner or later someone is going to buy Orion... and the product price will NOT remain anywhere near $1500 OR be "free" to non-commercial projects !! Well, I wouldn't count on this happening... I like Orion, but for projects on a budget, I think it is safer and less costly to maybe go with http://www.ejboss.org/ or http://www.evidian.com/jonas/index.htm. These are dedicated "open source" ejb servers hh if only Orion would open source. Admittedly, I don't know how the above ejb servers compare to orion. I know they don't have servlets/jsp... but then there is the open source free resin... Just have to point out that Resin is not free for commercial use. And if Orion is a take-over target, Resin is probably more so. Since Resin isn't a full J2EE server but is used for JSP/Servlets it's more likely to fit into someone's product portfolio (many EJB servers lack a decent web container), rather than Orion that would be a competitor to any existing server offering they have.

Re: startup classes?
this has been asked a few times before (last time only a few days ago, see list archive). Basically you will need to handle this in a servlet which has load-on-startup configured. If you really need you services to start when the server is started, you will have to configure the same for the web-app the servlet lives in. As for failover, I guess you will have to take care of that yourself. -Original Message- From: Andrej Gabara [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Date: Samstag, 28.

How do you do this in Orion? Weblogic allows you to define some classes to run in its properties file. How does this affect load-balancing and fail-over? Say server1 that runs the services crashes. How to make server2 (or another server) pick up those services?

Help with Finder query
Hello, I need help with defining a finder query. Here's the set up: CMP DataWatchItem has a member String called name. Its primary key is GUID guid (a homegrown globally unique identifier, that is Serializable). DataWatchItem works fine -- it can be created, found, and used. CMP DataWatchLogItem, has a member DataWatchItem called source. Its primary key is also a GUID. It also works fine. I want to define a finder method on DataWatchLogItem, findByName (String searchName). The logic is simple -- return a collection of DataWatchLogItem such that source.name equals searchName. How do I express this in orion-ejb-jar.xml? I tried finder-method query="$source-getUsername() = $1" It deploys but gives a runtime error 10/28/00 4:48 PM Error in bean DataWatchLogItem: Database Error java.sql.SQLException: General error in statement [select DataWatchLogItem.guid, DataWatchLogItem.source, DataWatchLogItem.runOn, DataWatchLogItem.evaluatedValue, DataWatchLogItem.errorString from DataWatchLogItem where DataWatchLogItem.source-getUsername() = 'vdhanda'] When I use,finder-method query="$source.username = $1" On deployment, I get the error: Auto-deploying lib (No previous deployment found)... Error compiling file:/C:/dev/lib/: Unable to process query: source was not a property/field mapped field (invalid '.' use) at column 16 in query '?source.username = ?1' Is expressing such a query possible in Orion?

Filters Help
Has anyone successfully used a filter to modify the original request?
I saw that the tutorial covered wrapping the response object to modify it,
but there wasn't any mention of doing something similar to the request.
Ideally, I'd like to look at the size of a request, and if the size is too
large, generate a new request to throw an error to the browser.
I assumed I could get it from javax.servlet.ServletRequest's
getContentLength method, ie:
...
public void doFilter(final ServletRequest request,final ServletResponse
response)
throws java.io.IOException, javax.servlet.ServletException
{
length = request.getContentLength();
...
but length is always 0 when I println to the console.
Using jdk 1.3, orion 1.4.0.
Any hints? Anyone else doing anything similar?

JMS implementation, is it for real?
Is Orion's JMS implementation for real? While it supports the simplistic behavior as demonstrated by the chat and coffeemaker demo it doesn't appear to support much else. JMS parts I can't get working: o Transactions. Doesn't seem to matter what you call: commit, rollback, etc. Doesn't make a difference. o Persistence: Make the change in the jms.xml to define a queue's persistent-file, set the message delivery mode to persistent, watch it get ignored. Has anyone had much luck with this? Perhaps SwiftMQ is the answer here (even though I want to use the MessageDrivenBeans). -- Jason Rimmer [EMAIL PROTECTED]
