Last updated on APRIL 04, 2019

Applies to:

Oracle Spatial and Graph - Version 11.2.0.1 and later
Information in this document applies to any platform.

Symptoms

Using part of the NCTI ontology which has around 3070 assertions with “someValuesFrom”, trying to create an Entailment (Rules Index) takes 100% CPU and never ends; the process has to be killed.

The command used:

EXECUTE sem_apis.create_entailment('atest_RI', sem_models('NCIT_ANATOMY_MODULE'), sem_rulebases('OWLPRIME'),sem_apis.REACH_CLOSURE, 'SVFH','INC=T DOP=4 RAW8=T HASH_PART=32');
