We are running z/OS V1R6 with Host-on-Demand V7 running within the HTTP
Server. We have noticed that the HTTP Server will just stop dispatching
tasks. After a while it will return to normal and go for many hours before
doing it again (already recycled it a few times). Needless to say the HOD
users think the system is down, blow themselves off their session and try
to get back on with CICS not knowing they left. T'is ugly.
Has anyone experienced this?? We have been working with IBM Level 3 for a
few days now trying to figure this out.
Thanks Jim Marshall
We have seen issues with the HTTP server this a couple of times. One
time we found that we were seeing sudden spikes in CPU by other tasks
the HTTP server was low priority. We had originally had it for testing
only and when we started using it for production, nobody change the
performance class.
The other issue we have run into is configuring the HTTP server to do
reverse lookups to reslove IP addresses to host names. HTTP server get
tied up waiting for responses that may never come.
However I am a bit confused. Once the user has the 3270 session up and
running they should never need to have any contact with the HTTP server.
They are straight Tn3270 client talking to the TN3270 server. At
least that is how it is in our setup. Heck we can bounce the HTTP
server and users with active HOD sessions never even know.
