JK2 runtime reconfiguration doesn't work on win2k3 IIS6

           Summary: JK2 runtime reconfiguration doesn't work on win2k3 IIS6
           Product: Tomcat 5
           Version: 5.0.27
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Native:JK
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: bjoern@syltonline.de


I set up a proof-of-concept on a Windows 2k3 Server std-ed (patched up-to-
date) with IIS6, JK 2.0.4 and Tomcat 5.0.27. IIS acts as the frontend-
webserver and does the authentication. It passes requests to the application-
contexts to the tomcats via JK2 / AJP13.

I was glad to hear that you lot work on runtime reconfiguration for JK2, so 
that draining a tomcat-node of the cluster is possible  without loosing a 
single request or session. I got it all working nicely, having a close eye on 
the docu and status page of JK.

Problem: When i reconfigure the workers2.properties , the status page of JK 
recognizes the change nicely (scoreboard info increases version and 
says "Updated config version to 1 Status information for child 0
"). But it doesn't update to the new values! And yes, I did increase the 
version number. I can't set a worker graceful=1 or alter the LB-Factor. But 
one thing works in runtime: When I add a worker, the JK takes it without a 
problem while running. But not when I delete one. As soon as i restart the 
Application-pool, all changes are taken nicely, but that's equivalent to 
restarting the Webserver.

My Registry-settings:
some are not nessesary, I know. ServerRoot is intended to be a random string, 
see BUG 30286.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Jakarta Isapi 
Redirector\2.0]
"extensionUri"="/jakarta/isapi_redirector2.dll"
"workersFile"="D:\\Java\\Jakarta-connector\\web_tom5test-jk2.0.4

"logLevel"="debug"
"uri_select"="parsed"
"log_file"="D:\\Java\\Jakarta-connector\\web_tom5test-jk2.0.4\\log.txt"

Please help on this one, because Draining of nodes is vital for a clustered 
high-availability environment.

thanks
