How to copy SMAT file during the process is running?

Sure.  Cycle the log file:

hcicmd -p -c “ save_cycle {in|out}”

Or, right click on the thread in the net monitor, select “Control”, “Full” and “Cycle Save”.  Select “In” if the thread is inbound and “Out” if the thread is outbound.

This will rename the current SMAT file with a .old extension and it will no longer be locked.

I am guessing you want to make sure no messages process while you are cycling.

One way would be to stop the inbound thread, wait for any queues to clear, then cycle. Don’t forget to restart the thread.

Another might be to place the inbound thread on hold (I have never tried this but no reason I can think of it would not work), wait for queues to clear,  then cycle. Don’t forget to release the inbound thread.

I do not know of any way to cause the cycling of the logs AND SMAT to occur absolutely at the same time.

Jae ,

This question is posted from time to time. We had the same problem in our AIX boxes but we didn’t want to cycle our interfaces continuously. We turned off the “save inbound/outbound messages” feature and created tclprocs to save the messages with their metadata (with the same format in the .msg and .idx files).

Now we can use hcismat or any other tool (grep, cat, more, etc.) to open the files (as read only) while receiving messages. So far we haven’t experienced any loss of data. I recommend this solution only if you need to see the content of those files on a regular basis.
