How to Enable/Populate "Interval Activity" (Option F.1) in Data Virtualization Server ISPF panel with activity data
The Interval Summary application allows you to view current and cumulative summarized interval trace information and access the information by means of Data Virtualization Server ISPF panels.
There are 3 parameters related to this feature as follows:
This parameter Enables/Disables the gathering of information
PARM ENABLEINTERVAL
MESSAGE ENABLE INTERVAL PROCESSING
EXPLAIN The ENABLEINTERVAL product parameter controls if interval
processing should be done or not. If this product parameter
is set to YES, then interval and interval summary records
will be created. These records can be displayed, written to
SMF and logged using tables.
This parameter controls the number of interval summary records to keep in memory
PARM LOGMEMORYINTERVALS
MESSAGE IN MEMORY SUMMARY INTERVAL COUNT
EXPLAIN The LOGMEMORYINTERVALS parameter controls the number of
interval summary records to keep in memory at one time.
if this parameter is set to zero, then no interval
summary records will be retained in memory. Setting this
parameter to zero will not prevent interval recording
from being performed. The interval summary records
kept in memory can be interactively displayed.
This parameter controls how often interval summary records are created
PARM RECORDINGINTERVAL
MESSAGE INTERVAL RECORDING PERIOD
EXPLAIN The RECORDINGINTERVAL controls how often interval summary
and per-client SMF and/or SQL records are created. These
records show what resources where used during the current
recording interval.
The interval value is specified in seconds and should
be a factor of one hour. In other words the value should
divide evenly into 3600.
