You should monitor the Physical Read and Physical Ctab rates on a regular basis. If the ratio of Physical/Logical Reads is too high, it indicates the Resident Page Pool could be too small for the workload and transaction mix. Similarly, if the ratio of Physical/Logical Ctabs is too high, it indicates the CTAB Pool could be too small for the workload and transaction mix. All other values on the display are informational only and, within the context of this display, do not represent tuning information.
You set the size of the Resident Page Pool with the RESIDENTPAGES Data Object Broker parameter and the size of the CTAB Pool with the CTABRESIDENT Data Object Broker parameter.
