(Doc ID 1956210.1)

Last updated on FEBRUARY 08, 2017

Applies to:

Oracle Spatial and Graph - Version 10.2.0.1 to 12.1.0.2 [Release 10.2 to 12.1]
Information in this document applies to any platform.

Symptoms

Queries on Spatial tables using operators like SDO_FILTER, SDO_RELATE or SDO_NN show performance issues due to Spatial index being ignored by the optimizer.

This happens despite the statistics being disassociated as described in <Note:1268383.1> Slow Performance when using SDO_RELATE/SDO_FILTER
