RE: Typical setting for Host name=???? /
From: Mark Thomas [mailto:ma...@apache.org] Sent: Friday, March 11, 2011 10:14 AM To: Tomcat Users List Subject: Re: Typical setting for Host name= / You can call it DefaultHost if you like. The only requirement is that the defaultHost specified in the Engine must be the name of a Host element contained by that Engine. snip Tomcat matches the Host header in the HTTP request to the host name. Any that don't match get sent to the default host. Ah, that makes things crystal clear. I was confused by trying to read the docs for the name attribute of the Host element too literally: Network name of this virtual host, as registered in your Domain Name Service server. Regardless of the case used to specify the hostname, Tomcat will convert it to lower case internally. One of the Hosts nested within an Engine MUST have a name that matches the defaultHost setting for that Engine. See Host Name Aliases for information on how to assign more than one network name to the same virtual host. And the introduction for the element as well: The Host element represents a virtual host, which is an association of a network name for a server (such as www.mycompany.com with the particular server on which Catalina is running. In order to be effective, this name must be registered in the Domain Name Service (DNS) server that manages the Internet domain you belong to - contact your Network Administrator for more information. Clearly what is there is correct, since it takes some extra effort to embed a Host header into the HTTP request if you don't have a DNS entry (messing with /etc/hosts would be one way). But that last bit of info for how Tomcat actually makes use of the header would be handy in the docs (I know - patches welcome :)) Is there any measurable performance optimization of using the name of the host that is expected to be in the request?

Re: Tomcat 7 Per Instance Memory Footprint in Hello World App.
Thomas, excellent, informative. So, given that a running 32-bit JVM on Linux will require at least 1GB RAM, total memory usage will not be JVM footprint * num instances, but rather, JVM footprint + num instances? The use case is transferring 20 client sites from LAMP stack to JVM + Tomcat 7 + MySQL + a Groovy.lang web framework I developed. Ideally I would separate client sites into tomcat instances, so as to isolate them from each other (i.e. redeploy/restart without affecting other instances), but that hinges entirely on the memory footprint. I have 16GB RAM available but was only planning on allocating 4-6GB RAM for this project. Only a couple of the sites in question do significant load (read: have been running on LAMP stack with 2GB RAM for several years without issue) -- --Noah Noah Cutler Web/Mobile Applications New Mind Development ad...@newminddevelopment.com http:://newminddevelopment.com On Tue, 2011-03-15 at 07:43 +0100, Thomas Freitag wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Noah, On 03/15/2011 06:25 AM, Noah Cutler wrote: can find nothing on the net re: this apparently basic question.

Actually, the 1GB are virtual memory usage, not everything is allocated in the physical memory. I'd say it is roughly: num instances * (JVM not shareable + JVM heapperm) + JVM shareable. JVM not shareable could be around 200-300MB. What heap sizes do you expect? The figures I gave for Tomcat were taken directly after startup. Because Tomcat starts additional threads for the connector thread pools these could increase (maybe 50MB instead of 5MB), and request processing needs some memory.

Ideally I would separate client sites into tomcat instances, so as to isolate them from each other (i.e. redeploy/restart without affecting other instances), but that hinges entirely on the memory footprint. You have to include the memory footprint of your applications into the calculation. If you configure small heap sizes the risk of getting OutOfMemoryErrors increases.

I have 16GB RAM available but was only planning on allocating 4-6GB RAM for this project. Only a couple of the sites in question do significant load (read: have been running on LAMP stack with 2GB RAM for several years without issue) I'd try a mixed approach: Run some tomcat instances with more than one application. Some restarts can be avoided by using hot deployments. The MemoryLeakPreventionListener [1] helps to check if your applications trigger some known memory leaks. That may fit your needs. I'm afraid it is very hard (or impossible) to start with an optimal configuration.

As David said, this does work with the thin driver, but I need the
service/load balancing functionality from OCI. Any more suggestions
are welcome!
You didn't say what connection pool you are using, but if you setup DBCP,
you could use the connectionInitSqls property to execute some proprietary
set_context call in Oracle e.g.
dbms_session.set_context('vpd_new','loc_code', pLocCode)
This might allow you to set a flag on a per connection pool basis for all

Assuming you have some locality of reference (adjacent instructions tend to be executed together, adjacent data items tend to be used together) then transferring 128 bits from main memory to cache is somewhat more likely to get you more useful bits of data in 4x32 bit items than in 2x64 bit items. - Peter
Experiences on ISAPI redirecct fails with Dotnet 4 - can anyone confirm
Hi, we have received a customer report, that the ISAPI redirect filter failed on an Windows 2003, IIS6.0 x64 when dotnet 4.0 is installed on the same site. The redirector was not able to catch the request prior to dotnet 4 and no pages were served (Server returned status 404) Switching the ASP framework version to 2.0 in the settings of IIS for the site solved the issue for the customer. Has anyone else seen this behavior? We cannot access the server so I cannot send more details on hardware or other modules. Additionally the .net4 will try to receive some descriptor.aspx from the application. This failed with an 404 as soon as the redirector worked because Tomcat does not know about this file.

This information is evidently available via JVMDI, so the JVM must be loading it somehow. Maybe poking around in OpenJDK would yield some fruitful results.

Re: Tomcat 7 Per Instance Memory Footprint in Hello World App.
Thomas, perfect, hours of searching Stackoverflow et al resolved in a single mailing list thread ;--) I will play around with various configs (per instance and multi-host per instance) in my local devel to get an idea of no-load resource usage; then, as you say, give some % more to avoid OOMEs in production. Obviously per instance is a memory hungry solution, albeit highly convenient. Placing all sites in a single instance is a possibility as well (and the most resource friendly), but I would need to implement some form of load balancing for the mid-business-day client A emergency restart (since all sites would be affected by the restart). Of course, I should have load balancing for the per instance solution as well to ensure application uptime even on restart. Hope the next version of Java addresses some of the issues with memory leaks beyond what Tomcat 7 is already doing. As a n00b to java land, this one issue invokes the most doubt, clearly java roots are not in the web per request model (i.e. request completes and everything, but session data flushed). Thanks for clarifying matters, Thomas, really helps to have an idea of what you are getting into prior to working on an implementation. -- --Noah Noah Cutler Web/Mobile Applications New Mind Development ad...@newminddevelopment.com http:://newminddevelopment.com On Tue, 2011-03-15 at 10:09 +0100, Thomas Freitag wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Noah, On 14.03.11 um 21:27, Noah Cutler wrote: So, given that a running 32-bit JVM on Linux will require at least 1GB RAM, total memory usage will not be JVM footprint * num instances, but rather, JVM footprint + num instances? Actually, the 1GB are virtual memory usage, not everything is allocated in the physical memory. I'd say it is roughly: num instances * (JVM not shareable + JVM heapperm) + JVM shareable. JVM not shareable could be around 200-300MB. What heap sizes do you expect? The figures I gave for Tomcat were taken directly after startup. Because Tomcat starts additional threads for the connector thread pools these could increase (maybe 50MB instead of 5MB), and request processing needs some memory. The use case is transferring 20 client sites from LAMP stack to JVM + Tomcat 7 + MySQL + a Groovy.lang web framework I developed. Ideally I would separate client sites into tomcat instances, so as to isolate them from each other (i.e. redeploy/restart without affecting other instances), but that hinges entirely on the memory footprint. You have to include the memory footprint of your applications into the calculation. If you configure small heap sizes the risk of getting OutOfMemoryErrors increases. If you deploy more than one application in your tomcat instances, average usage of heap memory, threads and database connections could be better. I have 16GB RAM available but was only planning on allocating 4-6GB RAM for this project. Only a couple of the sites in question do significant load (read: have been running on LAMP stack with 2GB RAM for several years without issue) I'd try a mixed approach: Run some tomcat instances with more than one application. Some restarts can be avoided by using hot deployments. The MemoryLeakPreventionListener [1] helps to check if your applications trigger some known memory leaks. That may fit your needs. I'm afraid it is very hard (or impossible) to start with an optimal configuration. You will have to make an educated guess (usually configure more ressources than necessary), monitor the resource usage, and adapt the configuration to your needs.

Obviously, your -Xmx settings have a lot to do with how much memory will be used, as well as the number of threads that are managed by the JVM, etc. The use case is transferring 20 client sites from LAMP stack to JVM + Tomcat 7 + MySQL + a Groovy.lang web framework I developed. Ideally I would separate client sites into tomcat instances, so as to isolate them from each other (i.e. redeploy/restart without affecting other instances), but that hinges entirely on the memory footprint. Ideally, you should be able to deploy/redeploy individual webapps without interfering with each other. If you have specific concerns, let us know and we might be able to comment. Running under a SecurityManager can certainly help protect webapps from each other -- things like prohibiting System.exit, etc. I have 16GB RAM available but was only planning on allocating 4-6GB RAM for this project. Only a couple of the sites in question do significant load (read: have been running on LAMP stack with 2GB RAM for several years without issue) We run each of our webapps in a separate JVM/Tomcat process to isolate them from resource conflicts -- we don't want one app to OOME and bring down the others, for instance. If you have some webapps that are particularly memory heavy or you are worried about, you can separate them and run the others together. Certainly running everything together in a single VM will be more memory efficient but they might interfere in various ways. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1/yWQACgkQ9CaO5/Lv0PBI0gCgq+wYJic2sWUoQsmM8aB9qHap QL8AoLwI0cphsgZDRR+T5cr6pcpGxDfz =L/Ot -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Hard time finding a but on Tomcat 7 (doesn't happen on 6.)
I'm trying to add mail.jar (Java Mail) to my app's lib (the problem also happens with tomcat's lib). It is quite simple. If I do it, I start getting Exception in thread http-bio-8080 error and it keeps printing it like in a loop. The problem starts as soon as I make a request to a servlet or to a jsf page. Everything goes fine on latest Tomcat 6 but it gives me this error on versions 7.0.8 and 7.0.11 (only tried on those). My environment is Windows 7 64-bit, JDK 7 64-bit 1.7.0-ea-b125. Just to be clear: I don't have to try sending an e-mail. Just adding the jar and making a request Unleashes the messages. These are the messages: Exception in thread http-bio-8080-exec-8 Exception in thread http-bio-8080-exec-9 ... And the numbers (exec-8, exec-9) keep growing, sometimes it skips one or two and after a few minutes I can get 4 or 5 of them even though I have made only one request. I am not getting stack traces anywhere. Maybe you can help me finding the cause of it. I'm kinda lost. Google is not helping me on this. Regards, Peter P.

Re: Tomcat 7 Per Instance Memory Footprint in Hello World App.
Chris, thanks for the excellent feedback; thus far this list exceeds Stackoverflow by orders of magnitude ;--) Re: ease of implementation, yes, a single instance with multiple virtual hosts is the way to go (similar setup to apache virtual hosts). However, some of the LAMP stack apps will have legacy/archived functionality that I have zero interest/time in porting over to JVM/Groovy framework. So, the plan is to mod_rewrite archived requests to php, along with static files (css,jss,html,etc.), and use Tomcat to serve up non-legacy dynamic content, connecting via AJP or mod_proxy. Amazed that you have been able to tweak JVM memory usage down to as little as 128mb, incredible. The OOME issue is a real one given my lack of experience in Java -- have @5 months Groovy under my belt and am enjoying it far too much to return to php -- so important client sites will have their own dedicated Tomcat instance; the rest, I'll virtual host in a single instance. Am interested in Tomcat 7's new DBCP model as well. Coupled with Groovy per request singleton (unlike per instance/application lifetime), I should be able create a db connection handle on request start and thereafter have all queries in the request run against this cached connection (could also do a true singleton, the most efficient, but as I understand, singletons are specific to the entire instance, and therefore will not work for a virtual hosts setup). Lots to learn clearly, but am loving the potential here, sky is the limit performance-wise... -- --Noah Noah Cutler Web/Mobile Applications New Mind Development ad...@newminddevelopment.com http:://newminddevelopment.com On Tue, 2011-03-15 at 16:26 -0400, Christopher Schultz wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Noah, On 3/15/2011 2:05 PM, Noah Cutler wrote: Obviously per instance is a memory hungry solution, albeit highly convenient.

Re: [OT] Migrated from 6.0.29 to 7.0.10, Now I get INFO: TLD skipped. URI: http://struts.apache.org/tags-bean is already defined
I don't know yet which project are you talking about, but why haven't you decided to migrate to JSF 2.0 or Spring MVC, instead of staying with Struts? My needs are mostly to create apps faster, specially in the GUI. The forms, the validation, the old basic HTML... I spend too much time doing that, and I remember how fast was using a RAD as Powerbuilder. It must be a better way to program than Using the 2004 Struts version. So what I'm most interested in, is the presentation. I did my research on JSF and I think it is the substitution of Struts, I mean if you have to create start a new project from scratch, there is no point in choosing Struts if JSF already exists. I was just about to migrate, but then Spring appeared and I postponed the issue, not deciding which way to follow (JSF or Spring MVC). I would also get a lot of benefits from the other Spring modules, such as the transactions, the DBMS access, etc. I know I'm spending time reinventing the weel, creating my own objects while Spring has a lot of functionality ready to use. I would like to know what Mark Thomas thinks about this, being a person involved with Spring Source.

We are still using Struts 1.3... making the upgrade to 2.x is ... non-trivial. I Still haven't decided between JSF and Spring.

But certainly I'm obsolete using 2004's Struts. I'm sure you will get a lot of opinions on all that. :) Struts 1.3 is still fine if it's meeting your needs.

Re: Hard time finding a but on Tomcat 7 (doesn't happen on 6.)
I told you, the latest one. So it's 1.44. The exact message is: Exception in thread http-bio-8080-exec-8 but the number at the end (8) varies and the number of messages like those varies also. Each new message comes with a higher ending number. So far I was unable to find out any correspondence between the number of the messages and anything else. The ending number seems to be related to the time between the last message and the new one. If it comes right away, the ending number is the next one. If the new message takes longer to show up it may skip 1 or 2 units. At first I thought it was related to java mail because I first had this problem when I added that jar and it seems I got rid of the problem when I removed the jar. Now, doing more extensive testing it seems the problem happens everytime I submit a request before I get the response from the last one which is odd because it works just fine with tomcat 6. So far I was only able to do it with with my application so I have created an empty web application and so far I have tested that with servlets, jsps and jsfs. Now I'm moving to test some frameworks until I can find out what exactly causes the issue with tomcat 7 and works properly on tomcat 6. Then we can figure out if it is a problem with the framework or tomcat. As soon as I have it isolated I will host the source somewhere so you can download. I advise you to not spend time on that since it seems that I am the only one having the issue. Thank you all for the willingness to help. Regards, Peter P.

Oh, yeah, I forgot to mention the logs. They don't show any sign of error. It's getting quite late here and I have to wake up early tomorrow so I will just give it a break and keep testing tomorrow.

Re: Hard time finding a but on Tomcat 7 (doesn't happen on 6.)
I'm still up. lol I'm using spring security, weld, primefaces and JPA (hibernate as provider). So far I have already tested regular JSPs, servlets, JSF (pure and getting values from managed bean), primefaces, weld, spring security and JPA one by one, isolated. I didn't get even 2 of these set up at the same time (not even the jars on lib). I followed the exact same configuration I did on my application. So far I was not able to reproduce the error. Tomorrow I may try combining them and/or try using VisualVM to analyze the error. Peter P.

Re: --Jvm option trouble with Windows service
To be absolutely sure I uninstalled both JRE and JDK, manually removing anything left behind, and reinstalled. This time the JRE did not have a server JVM indeed, so maybe another program had copied it. However the JDK has one and if I use it for the Tomcat server and later try to start it (with debugging enabled) I get this: [2011-03-16 06:12:23] [info] Commons Daemon procrun (1.0.5.0 32-bit) started [2011-03-16 06:12:23] [info] Service Tomcat7 name Apache Tomcat 7 [2011-03-16 06:12:23] [info] Service 'Tomcat7' installed [2011-03-16 06:12:23] [info] Commons Daemon procrun finished [2011-03-16 06:12:39] [debug] ( prunsrv.c:1494) Commons Daemon procrun log initialized [2011-03-16 06:12:39] [info] ( :0 ) Commons Daemon procrun (1.0.5.0 32-bit) started [2011-03-16 06:12:39] [info] ( :0 ) Debugging 'Tomcat7' Service...

I don't know if this is an hyperic issue or not, but i wonder if there is an option to fix it via tomcat/java configuration. the reason that i don't know if this is an hyperic or a tomcat/java configuration issue is because that when we use hyperic on other standard java daemon it doesn't have the same connection leak issue. That looks like an Hyperic issue to me. the issue is the following: hyperic, overtime, opens hundreds of jmx connection and never closes them.. after few hours our tomcat server is using 100% cpu without doing anything. once i stop hyperic agent, tomcat will go back to 0-1% cpu.. here is what we are seeing virtual vm: http://forums.hyperic.com/jiveforums/servlet/JiveServlet/download/1-11619-37096-2616/Capture.PNG is there any thing that we can do to fix this via java configuration?
