Archive feature class' extent not being set when stored as ST_Geometry

Description

If the archive class is stored using ST_Geometry when enabling archiving on a feature dataset or feature class, the archive class' layer's extent is not being set.

Because the archive class' layer's extent is not defined, spatial queries are automatically converted to full table scans by the geodatabase. This impacts the performance and scalability of the ArcSDE server.

Cause

When archiving is enabled for a feature dataset or feature class, all features in the Default version are copied into the archive class. In ArcGIS 9.2, the archive class' layer's extent is not being calculated, when all the features are placed in the archive.

A layer's extent can be detected by using the sdelayer -o describe_long command. The layer's extent or envelope is reported. In the example below, the envelope for the SEWER layer's historic archive is <EMPTY>.

Note:
The name of the Archive layer is the layer name suffixed with _H. If archiving is enabled multiple times the name must be unique so that a number is added (_Hx where x is a number).

Code:
D:\>sdelayer -o describe_long -l sewer_h,shape -i sde:oracle10g
