Package Components

The main components of the wgn_stats package are:

wgn_stats

This is the main pl/sql package as shipped by CA.

wgn_stats_cust

This is a pl/sql package that permits customizations to be made to wgn_stats.

wgn_stats_param

This is an abstract data type that is used to define how customized statistics are applied to an object.

The following components are installed in the database:

The wgn_stats package provides comprehensive configuration options, which reduce the need for package customizations. However, provision has still been made for customization if required.

Customization is handled via the wgn_stats_cust package, for which only a package specification is installed, defining the interfaces that are available for customization purposes. It is the responsibility of the DBA or CA professional services to define and implement the corresponding wgn_stats_cust package body, if customizations are required.

The user defined types wgn_stats_param and wgn_stats_param_tab are only of interest when implementing customizations.
