Need alternate means of shutting down Communication Channels

Hello,

We have a hung Java stack on a test system and cannot bring up the

Communication Channels screen to stop our Communication Channels. We

need a way to accomplish this. We can access some screens, such as

message monitoring, the management console, etc... but not Communication

Channels. We have noticed, that if we follow the SAP recommended

shutdown procedures and stop the Comm Channels first, then the system

restarts much quicker and there is less chance of data corruption.

Please advise.

Mike
