This information will further helps us in doing better PI Outage Activity.

I request you to go through the below information.

Step 1:

Before outage :

1. Stop all the sender channels

2. Analyze in sxmb_moni, sm58, smq1, smq2 and make sure all the messages are processed successfully.

3. Analyze in sxmb_moni_bpe the status of all bpm and make sure all are in status completed. (In case of, BPM)

4. Stop all the receiver channels.

      This is a nice concept but do you really think it is beneficial to manually restart manually when there are thousands of Communication Channels?

      Has anyone found a way to restart the channels programmatically?

      Hi Deidre,

      Thanks. There is no method to restart the communication channels programmatically. However, you can select thousand of channels with the help of select all option in Adapter Engine to select and deselect the PI communication channnels. You can go ahead and uncheck the PI communication channels whichever you dont have to restart (uncheck the list boxes) and remaining PI communication channels that you are already selected can be started manually if it is thousand also.

      Yes, we can pro grammatically perform the start and stop of channels by posting a http query to the communication channel server.
