Re: JK 1.2.28 - load balancer worker fails on startup with one worker down ?

If mod_jk had to do a DNS lookup each time it wants to send a packet to a backend Tomcat (or at least each time it wants to create a new connection to a backend Tomcat), that would be very inefficient. So, instead, mod_jk stores the IP address of each backend Tomcat, and during normal operation uses only that stored IP. But, as a convenience, in the configuration file, it allows you to specify the worker's host as a name if you wish; and if you do that, it does the lookup once at startup, to resolve that to an IP which it stores. But if it cannot at startup do this lookup and resolve the name to an IP, then it is stuck and cannot go further. Because if it did go further, then it would have to store this workers'host as an unresolved name, and then it would have to do a lookup during normal operation. CQFD.

Re: JK 1.2.28 - load balancer worker fails on startup with one worker down ?
Still continuing to guess.. This is about efficiency. If mod_jk had to do a DNS lookup each time it wants to send a packet to a backend Tomcat (or at least each time it wants to create a new connection to a backend Tomcat), that would be very inefficient. So, instead, mod_jk stores the IP address of each backend Tomcat, and during normal operation uses only that stored IP. But, as a convenience, in the configuration file, it allows you to specify the worker's host as a name if you wish; and if you do that, it does the lookup once at startup, to resolve that to an IP which it stores. But if it cannot at startup do this lookup and resolve the name to an IP, then it is stuck and cannot go further. Agreed - it cannot go further for this worker. I would expect an error to get logged and the load balanced worker to continue on to the next worker configured. Because if it did go further, then it would have to store this workers'host as an unresolved name, and then it would have to do a lookup during normal operation. CQFD. Now, I have really no idea if the code is really like that, but if not at least it seems logical, doesn't it ? ;-) Yes, it does seem logical, but flawed for a load balancer. If it was a normal worker, I would 100% agree it should quit. I will go ahead and configure all the Tomcat nodes by IP address in the mod_jk config file instead of the host name. The risk of having our whole production web application go down if one host is not available is not worth this convenient feature of mod_jk. :-)

The risk of having our whole production web application go down if one host is not available is not worth this convenient feature of mod_jk. :-) André is very close to our original reasoning: As he explained, it is only necessary, that the address is resolvable during startup. This is not related to whether the node does work or not. The latter is detected by the balancer dynamically. Why do we force the address to be resolvable during startup? This is because we think an address that has already formally no chance to work most likely presents a configuration error. I could phrase it like this: if you are using names as addresses (instead of IPs), then it is critical, that your DNS does work (and contain the data). In your case the missing data in DNS is close to a failed DNS and this will be a problem for almost all applications configured with names. Yes, there are too many error messages in this situation, but the first one said: worker mygpgby06 can't resolve tomcat address mygpgby06.mycompany.com So its not completely unlikely you can spot there's a name resolution problem. What remains for me is your suggestion, that the error is not a fatal one, since there are other balanced workers left. We could include such a check in the startup code, although I'm not really convinced, that your problem is a good reason for this.

Re: mod_jk ping_timeout revisit

Otherwise one single long running request will throw the whole worker out of the balancing for some time (due to the reply_timeout indicating a failed node). worker.template.socket_timeout=10 I'm not very much in favor of the socket_timeout, but well, if you think you need it.

Not sure, whether this is too specific for ApacheCon, but yes, if there is interest, I could give the talk. I'll submit a proposal and let the committee decide :) Concerning the proposal about a joined talk for httpd and mod_jk reverse proxy solutions: putting all this into one slot will be very dificult. Then we would need to keep it an overview thing and again people might not get the answers they are seeking (to many it depends without really explaining how you decide). So I prefer to do either a more specific talk (like one on mod_jk), or we would need two adjacent time slots. The latter gives maybe to much precious time ressources to this topic. How about a BOF session one evening where we can have more of a discussion? Hi guys. I realise that this is a discussion on the Tomcat list, and that the subject of ApacheCON presentations was brought up by Mark. Also, I'm probably not going to personally attend ApacheCON US (a bit far and expensive), so my suggestion is purely platonic. (*) This being said/written, there was a specific reason why I was suggesting this topic as both broad, and involving httpd as well as Tomcat experts, (and of course connector experts to sit in-between them). But it may depend on the kind of expected attendees of an ApacheCON US conference, of which I have no idea. The reason for the broadness is as follows : I believe that there are many more users/sysadmins/integrators of Apache httpd and Tomcat, than there are developers in each specific area. And, going from the users mailing lists of both Apache httpd and Tomcat, the first kind of question which the first category has, are broad questions of the kind : I would like to set up a configuration such that users call up URLs like so and so, and this results in requests being forwarded/balanced so an so to 3 backend Tomcat applications with URLs like so and so. What do I need to use for that ?. And what they are looking for, is some criteria and guidance as to what to choose among the different techniques available among the ones that exist within the broad Apache (ASF) palette (and maybe even outside of it), to get the job done. Not to say that there would not be a need for some session dedicated to drilling deeper into the pings and pong timeouts of mod_jk per se, but it's a different kind of issue, and different kind of presentation than what I had in mind. I attended ApacheCON in Amsterdam, and loved it. The sessions which I attended were extremely interesting and they were of the one-intensive-subject kind. One mildly frustrating aspect however, was that often there were several subjects I was interested in, but I could not go to all of them because the interesting sessions (for me) were often simultaneous. On the other hand, I was a bit surprised that there were basically no sessions (or very few) where several of these ASF tools were presented together in combination, as a means to an end. My proposal was something in that direction. I realise that considering the breadth of scope of the ASF projects nowadays, it is not possible to cover them all in one session, never mind finding the universally competent speakers. But the httpd+connector+Tomcat combination seems to be an almost ideal case, as it probably also represents 75% of the real-world configurations out there. Maybe a 2-hour session toward the beginning of the conference, to provide some general orientation, to be followed later on by sessions more dedicated to one aspect, when people see more clearly what they want or need. That wasn't really a 3-sentence summary, was it ?

what can Tomcat be doing that a profiler can't see?
In brief: I am load-testing an app running on Tomcat 6 NIO and am observing a big discrepancy between avg request latency as reported by JMeter (660ms) and the profiler (19ms). I would like to understand where is the delta being spent. In detail I have two windows boxes on the same subnet of a 1GB local network: box A is running our app on Tomcat 6 NIO; box B is running JMeter and YourKit GUI. JMeter is simulating 40 users, each repeatedly hitting the server with the same request (against port 8080), with 50ms think time. The response for each request is in plain text, about 10-20k worth. The request hits app-level cache 100% of the time, so JDBC connection aren't even being checked out of the cxn pool and no DB work is being done. After 20,000+ requests: -JMeter reports average latency of 661ms -The profiler reports a 19ms average and the same invocation count. YourKit is doing sampling. Given the huge discrepancy, I would like to determine where is 642ms (=661-19) being spent. Network latency should not be an issue.

Cookies and values with ':' in them
Hi,
The company I am working for is in the process of migrating from
Tomcat 5.x.x to Tomcat5.5.27. In doing so we noticed that the any
cookie value containing a colon will have the value trimmed up to
before that character. This is new. A work around is to add quotes
around the value, but we were hoping to avoid such changes:
To write:
Cookie cookie = new
Cookie(PROFILE_UPDATE_TS_X,2009-04-16T23:34:19Z);
cookie.setSecure(true);
cookie.setPath(/);
response.addCookie(cookie);
To read:
/**
* This is a convenience method for getting a cookie by name. If
the
* cookie is not present in the request, a null value will be
returned.
*/
protected Cookie getCookie ( String cookieName,
HttpServletRequest request ) {
Cookie[] cookies = request.getCookies();
for ( int i=0; icookies.length; i++ ) {
if ( cookies[i].getName().equals(cookieName) ) {
return cookies[i];
}
}
return null;
}
This is certainly a regression.

So, at this stage what we need to hear from you, the Tomcat user community, is what sort of topics would you like to see covered? Remember as well as regular sessions there can also be MeetUps, BOFs, symposiums, un-conference style activities, etc. Please feel free to pitch in with your suggestions on this thread and comment on suggestions made by other people. The more involved the community gets, the better the outcome is likely to be. Ideally, each idea for a session / BOF / symposium etc would include: - Title - Type of session - Short (sentence or two) abstract - Intended audience Although the call for papers has closed, there is some flexibility that would allow us to include sessions that weren't offered through the call for papers. So, if you would like to present on a Tomcat related topic then please feel free to offer to do that as well as letting us know what types of sessions you would like to attend.

There is also a relation between the ping_timeout and which connections do get checked during maintenance (the connection_ping_interval).

If I set connection_ping_interval to something like 10 (with a 1 ping_timeout), the cpong error shows up 1 minute after the tomcat request finished instead of 2. Go with connection_pool_minsize=0 and ignore very occasional info level messages. Will this affect my performance since it won't keep any connections in the pool and have to recreate one on every request? As long as the ping without pong isn't going to break anything (like you said, it's info, not error (just sounds like a not-good thing)), i'm fine with it. I send a request to tomcat via apache/mod_jk. Request's mount is mapped to worker, not loadbalancer. After successful request, Tomcat manager status shows the socket in stage 'R' and keeped alive socket count as 1. After 60 seconds, Tomcat manager status shows keeped alive socket count as 0, socket still in stage 'R' Above error happens 2 minutes after a request is finished, I'm assuming because the keep alive socket is not there anymore. You could have a look at netstat -an | grep 8009 on the Apache server (or whatever your AJP port is) and see, how the status of the connections changes, e.g. from ESTABLISHED to CLOSE_WAIT (remote side
Sharing an abandoned connection pool help
Hi everyone I have several web apps that are getting info from a database under the same username. I had it set up with a context in each app. However I have a limit on the number of connection I am allowed to have and I run into an issue with one app dominating the pool. For example, I have 10 connections (limited at the DB level) available to me and would like every app to have access to all 10. However if I put this in the context then the first app to use the pool will 'own' those connections and the other apps get nothing. Giving each app a set number of connection, like 2, 3, and 5, does not seem like a good solution. I tried putting the context in the conf/Catalina/myhost/ context.xml.default file and got much the same results. I would really love a solution that allows me to share the connection pool for each of the apps. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Need to share JVM for both tomcat and RMI server
Hi Jorge Thanks for your reply. I used Bootstrap.start() in my code to start tomcat. But i get the following exception in the spring frame work.
