When Validating a Topology in an ArcSDE geodatabase, the following error can occur:
"Validate Topology failed.
A failure was detected inside the topology engine overlay processor. [error is: -214747259]
Spatial index does not exist"
One of the feature classes that participates in the Topology has a Spatial Index (Grid size) of -1.
This can result from:
- Deleting the index from within ArcCatalog or with the SDE commands;
- Copying a feature class with an invalid grid size (in releases prior to 9.2);
- Copying a feature class from an SDE geodatabase stored within an RDBMS that does not support Grids (in releases prior to 9.2).
The Spatial Index for the feature class must be rebuilt.
