RE: Javac or jikesw with JDK 1.5?
I recently build a server during which I went from the base JRUN install, to Updater 5, running under JRE 1.5. It took me almost a day to finally figure out I needed to remove jikesw, as per that workaround, even though Updater pack 5 is supposed to be 1.5 compatible. ~ Jon -Original Message- From: Chris Boyce [mailto:[EMAIL PROTECTED] Sent: Monday, July 11, 2005 3:01 PM To: JRun-Talk Subject: Javac or jikesw with JDK 1.5? There was a bug (ID 55419) that is showing as resolved for Updater 5. It stated as a workaround, to remove jikesw from the bin directory and use javac instead. Should we continue to use javac under Updater 5 (and beyond)? I noticed - after a JRun restart - that javac was running on our server (running JDK 1.5, JRun Updater 5) and was using quite a lot of CPU time.

RE: Is JRun still relevant?
The problem I see with the results is that there is nothing there which makes it stand out as a remarkable alternative to the free offering of Tomcat. My personal experience with JRUN has been that compared to tomcat, everything is a struggle.. Installation with Tomcat was a breeze, and with JRUN (Admittedly because we use it coupled with CFMX) we have 3 pages of handwritten notes from the macromedia support tech who was assigned to our case when the installers failed us.. and if we deviate even slightly from those instructions, we have to uninstall and start again.. Deploying a Hibernate/Spring MVC application under Tomcat, was as simple as copying the folder structure. Deploying under JRUN, required a custom compile of Proxool, due to a JRUN Quirk and plenty of trial and error to determine which Jar's go where.. When I move forward, given the choice, I'm not going to pay for JRUN, when I can get less hassle from Tomcat. I have yet to find anything that stands out enough about JRUN which would convince me that I would get value for money from JRUN. I think it will be interesting to see which way Adobe go with JRUN, and I think alot of people are wondering the same. ~ Jon -Original Message- From: Alex Hubner [mailto:[EMAIL PROTECTED] It's nice to take a look on this: http://www.webperformanceinc.com/library/ServletReport/ Jrun is a hell of a good J2EE server.

RE: JRun Migration From 3.1 to 4
I'm a big fan of the Eclipse IDE for java. It will also handle JSP pages nicely.. It's open source, so there's no cost involved, and it has some great refactoring tools..You can change a variable with Refactor, Rename and have it replace any references to it in the code.

Date? What Date?
I know this may be a little less JRUN related, however it's seemingly the only un-common denominator, between two different instances, which are behaving differently. Basically I have a CFM, running inside an application, on a JRUN 4 application server, hitting an Oracle database. The CFM has a cfquery in it, which has one parameter. The query is running, and returning a row, which the criteria of the query should be eliminating. I have run this query in numerous places, from numerous clients, and cannot replicate the behavior experienced on the cold-fusion server. To add an element to this, I have a local JRUN 4 server, same patch-level, which runs correctly, and does not return the additional row. The portion of the query i have narrowed it down to, is the line or somedate = '26-Jun-2004' (The record's date is Jan 1st 2001).. I've checked server settings, date formats, etc etc..and have come up blank..Both my local server, and the App server should be running the same versions of pretty much everything, yet the debug output, shows exactly the same query.. on exactly the same database, returning a recordcount=1 on my local server, and 2 on the application server.

Re[3]: JRUN Stability
I was finally able to get some load-testing today, and it looks like that ActiveHandlerThreads setting will probably do some good. I ran tests against two different DB's, one with a larger data-load, and one with a smaller load. The smaller data load, we never experienced any problems, and we never went above 7 active threads, with 22 concurrent users. With the larger data load, we experienced vast slow-down on the server, and the active threads were much higher. We brushed on 25 a couple of times, but it recovered enough to continue.. We then focused everyone on a specific area that had been causing problems before. Within seconds we managed to max it out, and cause the server to grind to a halt. java.lang.RuntimeException: Request timed out waiting for an available thread to run. You may want to consider increasing the number of active threads in the thread pool. at jrunx.scheduler.ThreadPool$Throttle.enter(ThreadPool.java:125) at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:448 ) at jrunx.scheduler.ThreadPool$UpstreamMetrics.invokeRunnable(ThreadPool.java:29 4) at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66) Started flashing over the console running JRUN, and the metrics were showing a 25/39 threadcount w/18 sessions.

RE: Re[2]: JRUN Stability
Thanks to all for their input on this topic, I am getting more resource directed to this in the next day or, so, and will be running through some of the troubleshooting tips given here. I understand that many of you are running successfully, with many concurrent users, the question now, I have for those people, is what kind of scope is your application? Are we simply talking glorified web-sites with a little processing behind them, or are we talking full hard-code business applications. Our application falls heavily on the latter, and before I base conclusions on other peoples abilities to produce results under this environment, I want to be sure that we're in the same ballpark. One error which a user did capture during a server-halt the other day, was : Too many concurrent requests, jcp.endpoint.main.max.threads exceeded. I found documents on how to resolve this on JRUN3.. but none of the files that are referenced in that document, exist on my JRUN4 implimenation.Does anyone know where I can find the new settings fro JRUN4.

We spent $500 for macromedia tech support in order to solve the issue. Please check your jrun.xml. There is a service called ProxyService. You need to increase the value of the attribute named activeHandlerThreads to a number based on how busy your app is. I remember the default value is 15. Also, You can turn on Metrics logging to decide how many threads you need. Sometimes you could get the same error mentioned while using jsp forward tag. But I believe that Updater 3 may solve forwarding issue on JRun 4. for your info, Kathy --- Jon Austin [EMAIL PROTECTED] wrote: Thanks to all for their input on this topic, I am getting more resource directed to this in the next day or, so, and will be running through some of the troubleshooting tips given here. I understand that many of you are running successfully, with many concurrent users, the question now, I have for those people, is what kind of scope is your application? Are we simply talking glorified web-sites with a little processing behind them, or are we talking full hard-code business applications. Our application falls heavily on the latter, and before I base conclusions on other peoples abilities to produce results under this environment, I want to be sure that we're in the same ballpark. One error which a user did capture during a server-halt the other day, was : Too many concurrent requests, jcp.endpoint.main.max.threads exceeded. I found documents on how to resolve this on JRUN3.. but none of the files that are referenced in that document, exist on my JRUN4 implimenation.Does anyone know where I can find the new settings fro JRUN4.

Re[2]: JRUN Stability
Hi Drew, thanks for the quick response. DF I would be willing to bet that your issue is not in the APPLICATION SERVER, DF but in the code. This is simply not normal behavior for ColdFusion/JRun or DF it would not be used as widely as it is. That's somewhat of a surprising comment, Macromedia's forums were littered with reports of just how unstable CFMX for J2EE on JRUN4 is. >From that forum I was given the impression that such behavior IS quote common. It's definately interesting, and gives some glimmer of hope, to hear another side. Scouring the various forums available last night, I actually got the impression that it Isn't that widely used, exactly for that reason, that it isn't very stable. There also appeared to be a distinct lack of willing, or ability (not sure which) to help on Macromedia's part. DF First: are you using ColdFusion? or just JRun? I'm running CFMX for J2EE. The reason for that decision, to my knowledge, was simply to allow for distributed processing across clustered servers. I am coming in on the tail end of this project, so I don't know the full reasons for the design decisions made.All I do know, is that right now, I have a problem with the JRUN service on the server spiking, crashing, and requiring me to manually reset it. DF Second: What is your Web Server? We're using IIS on a separate box, using the JRUN connector. DF Third: depending on whether you are using ColdFusion or JRun, you will want DF to use the appropriate debugging tools to see what is going on. If you are DF using both, I would debug first one, then the other. I'm looking into debugging JRUN, the CFMX code is at least stable enough to support 2/3 users... so It's leaning toward JRUN simply not being man enough for the job. Especially in the face of examples such as : http://www.macromedia.com/cfusion/webforums/forum/messageview.cfm?catid=69threadid=806965 http://www.macromedia.com/cfusion/webforums/forum/messageview.cfm?catid=69threadid=799421 And it's the JRUN connector which ultimately errors. DF Hope this helps.

RE: JRUN Stability
The server in questions is windows 2000, SP4. We're using the Server version (/jrun4)and we're connecting to an Oracle backend. We're on JRUN Updater 3, and we've been running this configuration without issue, for about 6 months now. The problem appears to be load-based.. We usually don't have over 5 people on the server, developers are running their own local servers, so the database is already used to the load.. I'll look into the stack trace, but I do have to co-ordinate several very busy people, in order to get the load on the server, so I'm not sure when I'll be able to do that yet. Thanks, ~ Jon -Original Message- From: Stephen Dupre [mailto:[EMAIL PROTECTED] Did you try to get a stack trace when this was happening? (technote 18339 on www.macromedia.com http://www.macromedia.com ) What platform are you running on? Are you using the server version (/jrun4) or the standalone (/cfusionmx). What backend are you connecting to? Have you applied any patches (hotfixes, new database drivers, etc). I'd not ready to finger your code until we look at knownissues that might cause CPU spikes (environment-related, patches, etc).

RE: JRUN Stability
Well it's nice to know that it does work for someone.. While I do believe you, unfortunately we run a similar setup, and it's not even reliable with 15 concurrent users. Hopefully I can get this resolved before the customer gets loose on it. Thanks, ~ Jon -Original Message- From: Ben Groeneveld [mailto:[EMAIL PROTECTED] We run JRun4 with CFMX on win2k in a cluster supporting 1000s of concurrent users and it's quite reliable, believe me.Thanks, BenG.
