Hello,
I thought I would move the below thread over from deployment since this seems to be a much more active list, and also I am getting desparate here. I hope that's ok. I think the basic problem I'm having is Monitor thinks the instances it is starting are dying, even though they aren't. This causes them to only be accessible via direct connect (i.e. by specifying the port number in the URL) since wotaskd assigns them a negative instance ID as can be seen in my host config below. So the thing I need to figure out is, why does Monitor think my instances are dead when they are not. btw, I do have web services (i.e. apache) on and I'm running 10.4.x server. The rest of the thread is below...
I tried adding WODirectConnectEnabled false as an added application parameter on start (although I was never setting it to true in the first place, and I thought false was the default), and still the only way to connect to my application instances is by specifying the port number. Also, although Monitor actually does start my app and it is running, it reports the app as dying. I have tried giving my app a very long startup time (3 minutes) with the same results. And looking at the Host config via monitor shows that the instances that have been started using monitor are being given a negative host ID.
also, I can start my app from the command line using the same parameters Monitor says it uses and it starts fine, but even for that app I can only connect by specifying the port number in the URL.
I've pasted below my info copied from what Monitor is reporting as the startup options and the Host config.
Any help would be GREATLY appreciated because I really can't think of anything else to try other than trying to get it to run on Tomcat.
Thanks,
Jeff

This is a very simple question that I can't seem to find the answer to in the Deployment documentation. When I deploy an app with multiple instances, what URL am I supposed to use such that connections amont the instances are load-balanced? The only URL I can figure out how to use are the direct connect ones to a specific instances, but using one of those as my URL isn't going to allow load balancing, right?
Correct. First, turn off Direct Connect in deployment unless you have some (odd) reason for having it on. The URL should not have any instance number in it:
http://www.domain.com/cgi-bin/WebObjects/MyApp.woa
The woadaptor will talk to wotaskd and choose an appropriate instance based on how it is doing load balancing. I think you can also use -1 to tell it to do this:
http://www.domain.com/cgi-bin/WebObjects/MyApp.woa/-1
