Problem: Cannot zoom, pan or perform spatial queries on Oracle 8i Spatial feature classes loaded with ArcGIS

Description

Unable to zoom, pan, or perform spatial queries on Oracle 8i Spatial feature classes with measures or Z values, such as those having more than two dimensions, loaded with ArcGIS.

Cause

When ArcGIS loads a shapefile into a feature class on an ArcSDE for Oracle 8i server, it creates an R-tree Oracle Spatial index. The number of indexes dimensioned defaults to the number of dimensions in the shapefile, including Z and M.

R-tree spatial indexes do not work well when more than the X and Y dimensions are spatially indexed.

Solution or Workaround

Include the following DBTUNE parameter in the configuration keyword that loads the shapefile into the feature class.

SDO_INDEX_SHAPE "sdo_indx_dims=2"

SDO_INDEX_SHAPE can also contain other parameters used to create the spatial index. These parameters can be combined in the quoted list of parameter=value pairs. Please see the "ArcSDE Configuration and Tuning Guide for Oracle" for more information on using DBTUNE parameters to control feature class creation.
