    Hi all folks,
     last tuesday 13th we migrate from DSM to DMC, as IBM is now suggesting.
     After that we've had a lot of CPU problems. Without change any parameter in our configs, we've gone from a daily and poor 10% of CPU consumption, to a 100% CPU (99% db2 responsability) and our customers asking where is the problem.

     This is a picture of one of our DBs before and after the migration :

    This is a picture another DB, when the batch processes come, the CPU increase until 100%, with 99% CPU from DB2 :

    And last, this is the same DB,  with DMC been active only to days this week, do you imagine which days were?:

    I was wondering if there Is a  bug responsilbe of this  behaviour?

    Hi Matias,

    It is good if you can open a case and we can gather more data to investigate the high CPU utilization after migration to DMC.  Please let us know the case number.

    I would like to know if you check the monitoring profile for this Db2 is similar to the monitor profile settings in DSM?
