| 08:48.27 | Freeaqingme | Hi. Tomcat scans my webapps directory, and set up all war files it comes across. Is there any way to disable that? I'd like to define the ones I want to load explicitely using a context element so I can determine the paths they listen on myself |
| 08:51.59 | Canna | Freeaqingme: I have create a fold like $CATALINA_BASE/application and $CATALINA_BASE/conf/Catalina/localhost/name_of_the_webapps.xml with : <?xml version="1.0" encoding="UTF-8"?><Context docBase="${catalina.base}/applications/name_of_the_webapps/name_of_the_webapps.war" path="/PATH" reloadable="true"> |
| 08:52.41 | Canna | and bellow all the JDBC / JMS ressources |
| 08:53.58 | Canna | </Context> |
| 08:54.14 | Freeaqingme | and your host element? |
| 08:56.03 | Canna | Did you use the (HTTP) tomcat port to contact your webapps? |
| 08:56.20 | Freeaqingme | I'm using mod_jk via the ajp protocol |
| 08:56.37 | Canna | Ok, so what do you want to know about the Host element? |
| 08:57.09 | Freeaqingme | well, that is the element that's currently responsible for mapping my warfile to /warfile, rather than / |
| 08:57.28 | Freeaqingme | and so I added a context element for / , but still want to disable /warfile |
| 08:57.41 | Freeaqingme | (my app complains that it's got two running instances) |
| 08:57.55 | Freeaqingme | 2 instances of the app that is. they share the PID |
| 08:58.55 | Canna | Ok, i understand but i don't have the answer ;/ sorry maybe an other guys over here :) |
| 09:01.58 | Freeaqingme | hmz, someone suggests placing the war outside of the webapps dir |
| 09:02.03 | Freeaqingme | that's fugly though |
| 09:03.11 | Canna | This is what i do ^^ |
| 09:03.22 | Canna | with my folder /applications |
| 09:04.21 | Freeaqingme | heh |
| 09:04.33 | Freeaqingme | i'm changing webapps to webapps.auto, and put my wars in webapps |
| 09:04.35 | Freeaqingme | see what that does |
| 09:08.27 | Freeaqingme | Canna, awesome, that works |

| 17:19.06 | nbf | yeah but putting it in the war isn't ideal and neither is a global configuration |
| 17:19.14 | nbf | I'm currently using the war approach but I don't like it |
| 17:20.04 | nbf | the context is kind of like how the webapp is setup in the local environment |
| 17:20.30 | nbf | so you should be able to provide one for a given webapp, this is kind of a bug or design flaw in tomcat |
| 17:21.51 | topriddy | ...quick one, how many users can tomcat handle on an average? |
| 17:24.09 | whartung | all of them topriddy |
| 17:25.50 | whartung | nbf: JNDI is a global name space within the container. That's why there's the mapping components in the WARs to map the global JNDI name to the local name. The configuration of a resource is the context is a "feature" of Tomcat |
| 17:26.22 | topriddy | whartung: lol |
| 17:26.28 | topriddy | whartung: where should i check? |
| 17:26.46 | whartung | and the context represents the entire application, so it's no surprise that parts of it are not left behind when the application is redeployed |
| 17:26.54 | whartung | what's your use case topriddy |
| 17:27.07 | whartung | how many users to you want to support? |
| 17:27.38 | whartung | and what does that even mean in a generic case? |
| 17:28.00 | whartung | at best you could search for tomcat benchmarks against other containers to see what kind of stresses they put them under |
| 17:28.37 | whartung | last I checked, I can't say that tomcat is the fastest, but of the top tier containers, the differences for simple services are not dramatic, they're all at most 10% off of each other. |
| 17:29.06 | topriddy | whartung: some develope here telling me tomcat can only handle 200 users, and its a thread per request per user |
| 17:29.34 | whartung | tomcat comes configured for 200 users by default, 200 threads. but you can change that. |
| 17:29.40 | topriddy | i want to know where i can read about what is configured, the default say i have 2gb memory |
| 17:30.15 | topriddy | whartung: what file? and why one thread per user? say i have a massive school online app - 500users every point in time |
| 17:30.33 | topriddy | or a chat server powered by tomcat , randomly say WhatsApp? |
| 17:30.46 | topriddy | whartung: what file/ |
| 17:30.48 | topriddy | ? |
| 17:31.31 | whartung | sorry, it defaults to 150 threads |

| 17:31.49 | whartung | actually it may default to 200 |
| 17:32.01 | whartung | but the COMMENTED OUT configuration in server.xml is 150 |

| 20:48.13 | whartung | yea I saw that earlier, but can't really speak to it. I thnk we had similar problems with mod_proxy and Glassfish, and we went back to mod_jk |
| 20:49.30 | geoffl | the only thing i could think of was that the static content requests were creating an ajp thread and mod proxy wasnt releasing them properly so it was running out of threads |
| 20:50.06 | whartung | you could see that perhaps with a thread dump of tomcat |
| 20:53.14 | geoffl | is there even a solution if that is the case? |
| 20:56.33 | whartung | I don't know. We never really tracked down why mod_proxy was giving us the 503s, but mod_jk apparently doesn't so, so far so good. |

| 21:47.23 | geoffl | @medthomas, is that done in the tomcat connector setting for the ajp connector? |

| 21:48.24 | geoffl | im currently using mod_proxy |
| 22:09.35 | medthomas | geoffl: Look at the httpd docs. disbalereuse is a mod_proxy settings |
| 22:10.02 | geoffl | ok, i will dig into them. thanks |
| 22:12.03 | medthomas | does the same thing as the mod_jk one |
| 22:12.33 | medthomas | will fix the issue if httpd supports more concurrent requests that Tomcat has threads on the AJP connector |
| 22:14.05 | whartung | is where a lot of 503s come from medthomas ? |
| 22:14.10 | whartung | *is that |
| 22:20.52 | medthomas | whartung: Often. AJP uses persistent connections by default - one for each httpd thread. If httpd has more threads than Tomcat, Tomcat eventually reaches the point where all its threads are used and can't service the next httpd thread wanting to establish a connection |
| 22:21.27 | medthomas | depending on usage pattern, you disable reuse or increase threads on Tomcat |
| 22:21.45 | whartung | ah good to know, so it's important to ensure that apache doesn't have more children than tomcat can handle (I mean, that's "sorta" duh, but not intuitive without understanding what 503 is doing) |
