Configuring Object Volume Analysis

The Object Volume Analysis function reveals the effect of an application on overall disk access. This can help you balance the load and determine where Db2 data sets should be placed to reduce system congestion.

Procedure

Set parameter KD2_PFxx_OA_ECM to Y, which enables the base event collection needed to collect Object volume related information.
You can configure the following additional configuration parameters for Object Analysis:
  • KD2_PF01_OA_WAIT
  • KD2_PF01_OA_START
  • KD2_PF01_OA_THREAD
  • KD2_PF01_OA_INTV
Note: Do not set KD2_PF01_OA_START to Y unless your system has sufficient CPU space. If not, use the real-time control options to activate Object Analysis collection as needed. For more information, see Evaluating the cost of Object Analysis.
