To display an access plan graph by choosing from a list of explainable statements, follow these steps:
- In the Control Center, select the database you want and click on its
expansion icon to see the objects it contains. Click on the
Packages object (under the Application Objects
folder). Any existing Package objects are displayed in the pane on the
right side of the window (the contents pane).
- Click mouse button 2 on the package that you want in the contents pane and
select Show explainable statements from the pop-up menu. The
Explainable Statements window opens.
- To display other packages, select View->Filter, and change the
filtering criteria.
- Select one or more packages that have an explain snapshot (that
is, one whose entry in the Explain Snapshot column is "Yes"), then
select Selected->Show explainable statements (or use the pop-up
menu).
- The Explainable Statements window opens, listing all of the explainable
statements in the selected packages, and whether or not explain snapshots
exist for them.
- To display the access plan graph for a single explain snapshot, you can
double-click on a statement that has one (that is, one whose entry in the
Explain Snapshot column is "Yes").
- To display the access plan graph for one or more explain snapshots, select
statements that have explain snapshots, and then select Statement->Show
access plan (or use the pop-up menu).
