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.
