Tomcat and database connection
Greetings I would like to understand correctly how Tomcat database pool works. As I understand, when the application starts, a pool connection is created with *initialSize* connections (0 by default). Later on, new connections are created on demand of the application, untill it reaches the *maxActive* connections. If *maxActive* has been reached and the application requests for a new connection, the pool will wait *maxWait* milliseconds for a free connection. If any connection has been released, it will be kept as idle as long as *maxIdle* is not reached. No more connections will be created if there are *minIdle* or more connections in the pool in idle state. ¿Am I right? But I still have some questions: ¿How to see the pool connection state in real time? (idle connections, active connections, etc). We are using Introscope for monitoring an application, and we can see some stalled connections... but the maxActive parameter is far bigger (100) than the actived connections shown by Introscope (24). This is happening with Tomcat 5.5 on CentOs using Java 1.6. Thank you very much -- Un saludo, Tomás Tormo Franco Area de sistemas INDENOVA S.L.

Re: Tomcat and database connection
http://commons.apache.org/dbcp/configuration.html Thanks, I was already checking that. I don't know anything about Introscope. It just an monitoring tool application If maxActive is larger than the number of active connections, then there's nothing wrong there, is there? I'm not sure what you're trying to explain by that. Yes maxActive is larger than the active connections. Both queries (the one running and the one stalled) are trying to access the same register in BBDD (is the case when two different users are doing the same), but the query is just a simple SELECt, that's why I think is surprising that the second one is getting stalled... If you can see some stalled connections, take a thread dump to see what they're doing/waiting on. Could I use jvisualvm for that? I knew I could see threads state there, but I didn't know I could see why they are waiting... Sorry for my ignorance, I'm just starting in this field... :S On 13/05/10 11:05, Pid wrote: On 13/05/2010 09:35, Tomás Tormo wrote: Greetings I would like to understand correctly how Tomcat database pool works.

How to increase tomcat memory
Hi here it comes my question again... :D How to increase tomcat memory? I'm getting GC overhead limit exceeded.

How to increase memory form Tomcat 5.5
Hi I'm getting the OutOfMemory exception sometimes with some applications in tomcat 5.5 on Ubuntu. I've been searching on the internet how to give more memory to Tomcat, but the only way i found is to add the line set JAVA_OPTS=-server -Xms256m -Xmx512m (cause in this case i need that amount of memory) in the beginning of catalina.sh, but it doesn't work: when i check the Server Status in the Web Administration page of Tomcat, i always get the same value: 113 mb.

How to initialize variables when tomcat load a webservice?
Hi I'm developing a webservice wich has to initialize some variables when it is loaded by tomcat (just because otherwise it is too slow). Can this be done?

How to change the CLASSPATH in tomcat 5.028 for a concrete webservice
Hello I would like to change the classpath for a concrete webservice in Tomcat 5.028 because the webservice has to use a concrete folder in order to work. This folder should be in the CLASSPATH in order to make the webservice work properly and because the webservice can't find it, it doesn't work. I've tried a lot of ways to solve it: I tried to launch tomcat with the classpath modified from the shell itself(making it point to the folder), tried to export the classpath from startup.sh script, tried to export the classpath from catalina.sh script, tried to modify the CATALINA_OPTS variable, tried to put the folder in both lib and classes folders of the webservice folder... but nothing worked. could you please help me?

Re: *SPAM* Re: How to change the CLASSPATH in tomcat 5.028 for a concrete webservice
Hi David I'm using tomcat 5.028 in Ubuntu 6.10 . I've written a java applicattion wich uses a wrapper to communicate with an applicattion written in C, wich is the core of my applicattion. Both the wrapper and the core are third party applicattions, and because of that i don't have the source code, I just have the API. The third party sent me an example application wich uses the core. And, as I could see in the script wich lauches the application, this folder should be added to the classpath in order to be able to be located by the wrapper applicattion. The documentation of the wrapper just says that this folder has to exist with an specific name. My problem is that my applicattion works fine launched from shell (it founds the folder and uses the core perfectly) but it doesn't work as a webservice. It is not able to find the resource folder (let's call it cfg). As I can see in the catalina log, the application tries to load the resources (via ClassLoader I guess) and then launches an exception saying that is not able to find it. The client gets a HTTPErrorCode0. I think I've tried everything to make it find the folder, but I wasn't successful. do you have any idea? thank you very much David Smith escribió: I wold STRONLY recommend you DO NOT touch the CLASSPATH env variable.

Re: Noob needs help with a webservice wich uses resources located in a folder
Hello First of all thank you for your answer. The owner of tomcat it's my user, but the problem is that my system doesn't have the group (or user) tomcat. I tried to launch tomcat as root (just as a test) moving the folder to the same place as the .class is, and later the same moving the folder to webapps/service/WEB-INF/lib folder... but nothing worked... any other idea? I'll keep on trying. Thank you!! PTS escribió: If my quick read of your problem is correct, (only works when run from command line) then I would venture to say that you may have a rights issue. Who owns the app? By default Tomcat starts from the scripts as owner tomcat where as from the command line it is running as you (root or some admin level). Try chown and chgrp the app to tomcat and see if that helps. No even moving it into the folder does not give Tomcat the rights to access it. You could also change the access rights but I would be careful there as letting anyone execute code is not a good thing, but chgrp to tomcat and group executable would work. Just make sure you understand what the implications of the changes you make are, even on ownership and group membership.
