     The prompted schedmode isn't always available. It depends on the 
     COMMMethod you're using. If you're using shared memory then all the 
     client can do is go into polling mode. The client will tell you this 
     in the shcedule log file. I've only seen the prompted schedule work if 
     TCP/IP is used. Look in the schedule log file of the client. If the 
     server forces on prompted scheduling mode and the client can't comply 
     it will say so in the output.
     
     Prompted scheduling mode isn't available with a v3 client and a v2 
     server regardsless of the communication method.
     
     Another reason can be that the option is put in the wrong option file. 
     The schedmode option has to bo placed in the dsm.sys file and not the 
     dsm.opt file

I have a problem with  options in ADSM on AIX. There's an option that 
decides if the clients are to use
 polling or promted mode whith the ADSM scheduler (SCHEDMODE).
     
Default mode is polling, and if you set schedmode on the AIX client (in the 
dsm.sys file) to promted and has the same
mode on the server the scheduler function stops working on AIX. This 
function works just fine with Windows NT cilents though.
The problem I have on AIX clients is that when the server and the client 
both are set to schedmode promted - the client doesn't recieve a schedule 
from the ADSM server, and the adsm_sched.log tells that the ADSM server 
does not support polling.
According to the ADSM documentetation both of these options should be 
possible to apply on any of my platforms;
eg both NT AS/400 and AIX.
     
At the moment the only way to get the scheduler to work on the AIX clients 
is to let them have polling schedmode.
So I had to set the options on the server to any so that the NT clients 
could continue with promtede mode.
     
The question is : Has anyone seen this before and could give me a hint?? 
My qustomer's wish is that all clients should run in promted mode so
the server has full control over the ADSM clients
     
Thanks
