RE: Connection reset by peer: socket write error
Hi Dileep, Now I understood your problem clearly. This is quite normal. When the database goes down all the connection object in your pool become Invalid. Basically you need to create new connections in order to connect to the restarted db. When you use JRun pooling, JRun is handling this. So either you can use JRun pooling or change your algorithm accordingly. This is absolutely nothing to do with query. Regards Savant -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, April 01, 2002 11:11 PM To: JRun-Talk Subject: RE: Connection reset by peer: socket write error Thanks savant for writing. We are using Oracle 8.1.5 version. And I get the problem when I use my connectio pooling, but if I use JRun's connection pooling then it works fine. So the problem lies somewhere in my connection pooling. I have tried resetting the connection to null after closing but that also doesn't work. Let me describe a bit more about the situation in that this error occurs. We have a Oracle database that is down for 15 minutes everyday in the night for some backup process. When database is up we get "Connection reset by peer", until we restart the JRun server. But that doesn't happen using JRun's connection pool. Now do you still think that this is related to query not pool?

RE: Macromedia IDE's
Hi, First off, Dreamweaver/Ultardev/JRun can all exist on the same machine - they all have individual run-time components. As for what tool to 'learn' DHTML, well there isn't really one - Dreamweaver 4 will code the DHTML for you via its design interface and I suppose you could learn from reverse engineering the code - but obviously MM code is designed to be compatible across a widerange of platforms and can be difficult to decipher. Ultardev is basically Dreamweaver with Database development tools bolted on. If you are looking to code JSP and DHTML then yes Ultradev is your tool, if you are looking to simply create HTML/DHTML - get Dreamwaver. There is a Dreamweaver/Ultradev Studio package which you should go for. Best Neil Team Macromedia Spectra __ This list and all House of Fusion resources hosted by CFHosting.com.

Macromedia IDE's
I have a young man who will be comming to work part time with us and who has no programming background, but who would like to learn HTML, Flash and DHTML. Currently I am using JRUN Studio 3.01 with JRUN 3.1 as my IDE, which is OK for me and the more experienced developers to develop JSP's with. But I'm interested in obtaining a more powerful DHTML IDE, particularly one that would come with a JavaScript code generator for creating DHTML, that could be used by someone who has little programming experience. I've been reviewing the available IDE's on Allaire's site. Does anyone have any experience with Macromedia's Dreamweaver UltraDev 4? Would that IDE be suitable for someone learning only DHTML, or would just Dreamweaver 4 be sufficient. Also, can Dreamweaver UltraDev 4 co-exists on the same machine that JRUN Studio 3.01 is installed on? Thanks in advance for any advice/recommendations/experiences with Dreamweaver UltraDev 4 vs Dreamweaver 4. Celeste __ This list and all House of Fusion resources hosted by CFHosting.com.

Calculating ROI, especially with something like this, is not easy and often arbitrary. But basically you need to put together the cost of doing load testing (hours + software, if necessary). Then, put together the costs for a couple scenarios. One should be the cost of the applications server going down. Estimate the amount of time it would take you to rebuild your environment. Now, add in dollars for the amount of sales lost while your server is down. Add more for the confidence lost by customers who tried to visit your site during downtime (this can be large, imagine if 100 customers never return at $100/yr/customer). Give a cost scenario during a promotion. Again, explain that this is pretty much inevitable if you don't know at what point your application will break and where.

This is called politics. And the higher you move up as an IT professional, the more important the "how well you play the political game" becomes vs. "how often you are right and your boss is wrong". Perhaps someone else on this list has a better approach to convincing their management team for taking the time and the money to do things such as testing. I'm always interested in hearing other/better approaches. But for me, this is the way I have approached all "opposition" to any IT recommendation that may be viewed as "not necessary, too costly, etc.", testing included. As I mentioned before, people and companies both make mistakes, and hopefully learn from them. Sometimes you just have to let your upper management make what you know is a decision that will probably come back to haunt them, and then just move forward from that point on.

But my point wasn't "what do we do if the bosses don't listen" so much as "why aren't we pushing testing (especially load testing) more". I think there's a sense in many that it's not important, or it's too difficult, etc. While it's true that many sites may not get thousands (or tens of thousands) of hits in a day, it's reasonable for one getting just hundreds to get several at once, and there are clearly issues (like the one that touched off this thread) that may be triggered with just such a low level of load. If I seem to be on a bit of a bandwagon for load testing, even for "smaller shops", I am. And as has been pointed out, cost of tools isn't really the issue. I'm curious for the kinds of arguments against it that have either kept people from pursuing it or, even in the face of these assertions of the low costs and good benefits, why they would still say "nah, not going to bother". /charlie > -Original Message- > From: Haseltine, Celeste [mailto:[EMAIL PROTECTED]] > Sent: Friday, March 29, 2002 10:55 AM > To: JRun-Talk > Subject: RE: load testing (was RE: Difficult To Reproduce Session Issue) > > > Charlie, > > I just try to point out the business cases for testing.

I hope you can understand my point of view. > >>From what I know about the history of the previous Duplicate Session issue > it seems we did reproduce it, we then fixed it , issued a security bulletin > and then created a distinct patch available for download.

Re: Difficult To Reproduce Session Issue
Jeff, We will work with 2 customers from this thread. We have started contacting them already. You did not mention if you are experiencing this issue are if you are just concerned. Also keep in mind that it is very common to find issues like these eventually reveal no associations to past issues. No matter how it ends up I will post the findings to this list. >From what I know about the history of the previous Duplicate Session issue it seems we did reproduce it, we then fixed it , issued a security bulletin and then created a distinct patch available for download.

RE: Connection reset by peer: socket write error
Thanks savant for writing. We are using Oracle 8.1.5 version. And I get the problem when I use my connectio pooling, but if I use JRun's connection pooling then it works fine. So the problem lies somewhere in my connection pooling. I have tried resetting the connection to null after closing but that also doesn't work. Let me describe a bit more about the situation in that this error occurs. We have a Oracle database that is down for 15 minutes everyday in the night for some backup process. When database is up we get "Connection reset by peer", until we restart the JRun server. But that doesn't happen using JRun's connection pool. Now do you still think that this is related to query not pool?

Try to run the same SQL from SQLPLUS. If that also fails problem is not with JAVA .Problem is with Oracle. I have encountered this problem while I was running a complicated SQL having a few inner Queries and Distinct clauses. Funny thing was once I removed some Distinct clause the SQL worked. The problem is still a misery.We moved to Oracle 8.1.7 then everything went fine.

Re: Difficult To Reproduce Session Issue
I don't understand this attitude. We're talking about a very serious bug that Macromedia has known about for close to a year now. It got through their testing/release process twice. They had a similar "we will do whatever it takes to fix this problem" response in November, which resulted in a patch that didn't fix the problem. I wouldn't call this a "great" response. More like feeble. If you're using JRun for development, or for an intranet where session affinity isn't important, then I can understand. But if you continue to use it in other environments, you are merely ignoring the issue. charles arehart wrote: > Wow, great way to respond to the issue.
