Hello. This topic is specifically about the following two settings found in the mod_jk workers.properties files: - local_worker - local_worker_only
The official docu is at: http://jakarta.apache.org/tomcat/connectors-doc/jk2/jk/workershowto.html I found the explanation a little unclear and found a more succinct version here: http://sourceforge.net/mailarchive/message.php?msg_id=6782552 anonymous wrote : local_worker=1 indicates that it"s running on the same box as apache. | local_worker=0 indicates it"s running elsewhere. | | local_worker_only=1 says only send new requests (e.g. no jsessionid | cookie/url) to workers with local_worker=1. | local_worker_only=0 says new requests to any server. | | How it helps is that when you need to do maintenance on ww2, set | local_worker_only=1 on ww1 and do a graceful restart on apache. New | requests to ww1 will all go to the ww1 Tomcat instance. If a requests | comes to apache on ww1 with a ww2 jsessionid, it will still route the | request to the correct Tomcat instance. Eventually the sessions on ww2 | all die off and you can cleanly bring down the instance without killing | off your users. You obviously need some other mechanism to stop HTTP | requests from being directed to apache on ww2. I'm not sure what nodes/servers are involved here. Questions: 1) Are ww1 and ww2 only tomcat instances or apache+tomcat instances? 2) Is it assumed that there is a third apache instance infront of them or a loadbalancer? 3) Is the quoted explanation even still correct? 4) Would a quick explanation of the servers/nodes (apache/tomcat) involved and an example along the lines of the quoted one be possible?
