Re: mod_jk load balancing problem
Hello, The problem I detected is that client has to send three requests for home page as it contains frames. How can I force mod_jk to send all requests to one server. I come to this result while I shutdown one server called tomcat3 and restart a tomcat on that machine (tomcat3) with no application. Frames showed error 404 that should be there as there were no page on that machine (tomcat3). I concluded that all request is not been treated by one server. Can someone help me out.

RE: mod_jk - load balancing
Hi Andrew, It will mark a worker as down and only send requests to working workers. There is a separate thread that checks the availability of all workers in an configurable time period which will mark the worker as available/functioning again when it becomes available, where after it will receive requests again. This is new functionality in the latest version of modjk(.27) I am not sure whether the request that determined the unavailability of the worker will be retried though, I don't think so. There has been a previous thread in the list that discussed retrying requests and the caching of request. I believe the conclusion was that it would be possible to implement but not necessarily simple.

Re: mod_jk load balancing and cluster node health
Nathan E. Pilling wrote: Is it possible to configure mod_jk to check node status by requesting a specific web application path to see if a cluster node is healthy (and should be included or excluded from the cluster)? I have a web application that runs across multiple tomcat instances and any request be processed by any tomcat node. If an instance of the web app on one of the tomcat servers is not configured properly, I want the connector to exclude it from the cluster. I have written a servlet that returns a status of 503 if something is wrong or 200 if everything is okay. There's not the full story build in yet, but you can combine the various pieces to get the same result: Write an external script, that refularly calls your servlet and add ;jsessionid=.MYNODENAME to the end of the URL (but before the query string). The load balancer will then send the request to it's member named MYNODENAME (stickyness). Now you set fail_on_status to 503 for all LB members. Then the load balancer should put the node into ERROR, whenever it sees a 503 coming back for any request. See http://tomcat.apache.org/connectors-doc/reference/workers.html for fail_on_status. Does that sound plausible?

Regards Adding to Mladen's answer: if you have only one app per Tomcat, you can use the activation attribute of an LB member (active, disabled, stopped) to tell the LB, if it should send requests to the member. Look at activation in http://tomcat.apache.org/connectors-doc/reference/workers.html Another possibility is to use the attribute fail_on_status with a value of 503, because an existing but stopped Tomcat context will answer requests with http 503. You could check, whether 503 or -503 suites you better. See the same docs page. Starting from 1.2.27 there will also be a possibility to express an activation state in the mapping table uriworkermap.properties, which would allow to disable or stop a forwarding per URL and per node. Unfortunately the nsapi plugin doesn't actually support the forwarding via uriworkermap.properties. It only allows setting the uri to worker map via NameTrans in obj.conf. Something we could improve, but at the moment there seems to be no huge interest in the nsapi plugin.

Hi Peter thanks for your reply. I configure only files that I mention on my previous e-mail. The instructions are written a bit confusing. They are mention some mod_jk.dll that needs to be used on Windows machines, but I haven't found any where I could download it. I'm trying to use this for the first time so I would appreciate if you or somebody else could send me some examples files which would make my environment work. I will use different ajp13 for each instance. As mention first I'd like to make work one instance. After it should be easy to make work all of them.
