| 23:25.48 | sysc | Any major cons to running apps isolated? Tomcat process sharing JVM for each app/service? |
| 23:33.30 | jasonb | sysc: Your question is ambiguously worded and/or not explained in enough detail. Can you please re-word it more clearly & verbosely? |
| 23:34.41 | sysc | Currently I run all my apps/services under 1 tomcat instance. When I do deploys obviously it affects everything. If I were to isolate each one (use a seperate tomcat instance for each) I would have more reliable uptime but are the any major cons to a setup like that? |
| 23:34.52 | sysc | Obviously more resources (memory etc) |
| 23:35.24 | sysc | but anything else? |
| 23:39.23 | sysc | Still a crappy question? Sorry, I know what I am trying to do but my terminology sucks... Still new to Tomcat. |
| 23:39.34 | jasonb | It requires more RAM, more CPU (because threads of connectors can't be shared that way), it requres maintaining updates and configs of more than one Tomcat instance, it requires monitoring of more than one Tomcat instance, it requires people deploying/debugging/upgrading to know how to find out which Tomcat node has the webapp they want to work with, it means that one Tomcat and/or JVM might be configured differently than the ot |
| 23:39.35 | jasonb | nwanted or perplexing difference in behavior.. |
| 23:39.47 | jasonb | (no, your question is now clearly worded and unambiguous) |
| 23:40.43 | sysc | There is no other way to get what I am looking for though correct? |
| 23:40.49 | sysc | Besides switching to glassfish or something |
| 23:41.07 | jasonb | It leaves more opportunity for inconsistencies (in configuration or software versions) leading to security vulnerabilities. |
| 23:41.29 | jasonb | Well, no, sometimes you can really only expand by spinning up more JVMs. |
| 23:42.00 | sysc | I figured |
| 23:42.06 | jasonb | The good news is: if your business is growing and you're forced to spin up new JVMs, this is likely to be a symptom of very positive business growth, and that's a good thing. |
| 23:42.25 | jasonb | It just means that maintaining all that becomes harder and less simple.. but you wouldn't be the first in that boat. |
| 23:43.55 | sysc | Thanks for the information, that stinks but it's kind of what I thought. |
| 23:44.42 | jasonb | There are ways you can share more of it using Tomcat.. Are you aware of the CATALINA_HOME vs CATALINA_BASE split? |
| 23:45.48 | sysc | That's what I am talking about, Sharing the same JVM but isolating each app to a seperate tomcat instance. So that when I have to restart one it does not affect the others. |
| 23:46.00 | sysc | At least that's what I *think* I am talking about :) |
| 23:46.38 | jasonb | Right, and then there's a way to share the same Tomcat binary installation, just have different config files and potentially scripts/libraries for each running Tomcat instance (CATALINA_HOME vs CATALINA_BASE split). |
| 23:47.43 | sysc | Ah ok, any docs I can read up on that? What's the advantage/disadvantage seems like from a maintenance standpoint its probably pretty similar |
| 23:47.57 | sysc | still managing all kinds of ports ->> directory mappings |
| 23:49.11 | jasonb | Well, the advantage is that when you know you want to upgrade Tomcat itself (Tomcat's jars/binaries) that you upgrade it once, in one directory, for all running instance of Tomcat on a machine, instead of upgrading N number of Tomcat installations per machine. |
| 23:49.28 | sysc | Makes sense |
| 23:50.20 | sysc | Disadvantages? |
| 23:50.34 | sysc | Besides management overhead, still as resource intense as the full on split? |
| 23:51.21 | jasonb | There aren't really disadvantages.. it's very configurable. |
| 23:51.34 | sysc | hmm |
| 23:51.53 | sysc | So restarting one specific container/app how would that look? |
| 23:52.38 | jasonb | Restarting always depends on how you installed it in the first place, not really on how Tomcat itself was written (mainly since Tomcat doesn't not attempt to integrate tightly with any OS other than Windows). |
| 23:53.19 | sysc | ubuntu install, so currently service restart tomcat6 but, if I do a deploy for a specific application |
| 23:53.32 | sysc | and I need to restart it, but not take down all of the other services. |
| 23:55.38 | jasonb | Look into the tomcat-user package. |
| 23:58.50 | sysc | Ok now you have me confused, so the Catalina_Home vs Catalina_Base split won't do what I am looking for? |
| 23:59.44 | jasonb | It will. |
| 23:59.54 | jasonb | The tomcat-user deb package helps with that. |
