Distribute FLOSS for Windows, Linux, *BSD, and MacOS X with BitTorrent MyODBC is but one way to connect code to server. I am not running ASP.NET servers so I don't use the .NET Connector. There was another project or two (like the .Net Connector) that was written for VB. I found a copy of the source of one of them but all of the projects I have found seem to be abandoned (which means, you are responsible for your own support). The C++ API is packaged with the server) Since I don't have time to update these legacy connectors to keep up with the new server technology (Views, SPROCS, INFORMATION_SCHEMA, 4.1+ password hashing, etc) and I don't have enough time to debug it when I get it wrong (which everyone does), I decided to go with the tested and prepackaged MyODBC. Now, if anyone else has or knows of a product that will work from ASP (not ASP.Net) or VB (not VB.NET) and doesn't require the .NET runtime library to be installed I would love to hear from you. Please respond to the list so that everyone has a chance to get in on it, too. Thanks, Shawn Green Database Administrator Unimin Corporation - Spruce Pine PS. I am sure that if I tried really hard, I could call a compiled version of the C++ API from VB but I don't want to go through the motions of converting all of the APIs function calls into VB declare statements. I have thought about it, but decided against it. Once again, it's a matter of time and support. - S

database pooling problem
Hello, I am working with a traditional database pooling class basically putting connection objects into a Vector. When I run the code from a main, it appears solid. I have run 10s of thousands of back to back queries and all is good. Problem is when I connect it to a web-app, and reboot the webserver a couple of times, I get a message from the driver stating Too many connection and I am done. Upon thinking about this, I figured my traditional Vector of connections, is getting created over and over, each time someone bumps the web server with a new class, etc. So I start out with 10 connections, then another 10 and another 10 and eventually I guess the driver has no more connections to give? Anyway, this list is possibly the wrong, list, but I would hope there are some developers here that may lend a hand or link. So I am not happy with what I have created nor the way it works on the web server. Does anyone have any ideas how I should handle this? in a web-based environment. Thanks, Scott

Thanks, Scott No matter which list you submit to, you need to provide more details. Technically what you are asking is a little off-topic (more about making a pool work with a web server than just making the connection, right?) But if you bring the question to the list, someone _may_ be able to pitch in and help. Now exactly WHO can help (and to what degree they can help) completely depends on WHICH web server you use (there are dozens, you know...), HOW you initialize your pool (again many methods available), HOW you take and return connections from your pool (ditto), and which languages are in use in this entire process (again dozens of options). Just telling us that you use a web-server did not provide nearly enough information as there are literally thousands of combinations of ways to do what you described. Please tell whichever list you submit to: What OS you are using Which web server you are using What languages you are using And you will need to supply some code examples, too.

Re: database pooling problem
Apache 1.3 with php (not sure about tomcat) is a pre forked daemon. Any connection pooling numbers will be per child. Try setting your connection numbers per child (for most php apps this is 1) and let us know what happens. I'm guessing it will create as many connections as there are apache children. For more info see the fork() man page. -Eric On Mon, 7 Mar 2005 17:04:47 -0500, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Scott Purcell [EMAIL PROTECTED] wrote on 03/07/2005 04:59:27 PM: Thanks Sean, I am using standalone Apache/Tomcat 4.1.31 mysql \s -- mysql Ver 12.21 Distrib 4.0.15, for Win95/Win98 (i32) Connection id: 184 SSL:Not in use Server version: 4.0.15-max-debug Protocol version: 10 Connection: localhost via TCP/IP Client characterset:latin1 Server characterset:latin1 TCP port: 3306 -- mysql I am using Java to code with and I am using a driver called: org.gjt.mm.mysql.Driver My connection class is too large to submit to the list, or I would submit it.

For more info see the fork() man page. -Eric Actually the connection is on per worker process. Tomcat response to apache's children's requests, so it would be, at worst, one connnection per tomcat worker, which should be a smaller number than apache children/threads. There are methods for tomcat workers to also share a connection pool, but I've never used them. For my needs dropping and creating connections has been better (shared servers). I'd look at the tomcat connection pooling information on the apache site as a place to start rather than the web-sever. Hopefully you have configured tomcat to just handle the .jsp page not ALL PAGES.
