Usage
The data collected in
the
section_actuals monitor element or per connection
using
WLM_SET_CONN_ENV is used when a section explain
is performed using the EXPLAIN_FROM_ACTIVITY stored procedure. This
data is used during EXPLAIN processing to populate the EXPLAIN_ACTUALS
explain table and represents the runtime statistics for the operators
in the access plan.
Note: - Section actuals are only available if they have been
enabled (set to BASE) using the section_actuals database
configuration parameter or if they have been enabled for a particular
application using the WLM_SET_CONN_ENV stored procedure. For more
information describing the stored procedure, see WLM_SET_CONN_ENV
- The section_actuals setting
specified by the WLM_SET_CONN_ENV procedure for an application takes
effect immediately.
