Execute SEM_APIS.CREATE_RULEBASE('ecc_md_rb')
--Insert to mdsys.semr_ecc_md_rb Values(.............)
BEGIN
SEM_APIS.CREATE_RULES_INDEX(
'ecc_rule_indx',
SEM_Models('FOUNDATION'),
SEM_Rulebases('RDFS','ecc_dm_rb'));
END;
Create rule index statement is running more than 8hrs and i tried with the sem_apis.create_entailment its also giving the same Temp table space error.
Please find the below error details
BEGIN sem_apis.create_entailment('ecc_rule_inx', sem_models('FOUNDATION'), sem_rulebases('OWLPRIME','ecc_dm_rb'),SEM_APIS.REACH_CLOSURE,'RDFS2-, RDFS3-, RDFS4a-, RDFS4b-, RDFS5-, RDFS6-, RDFS7-, RDFS8-, RDFS9-, RDFS10-, RDFS11-, RDFS12-, RDFS13-','USER_RULES=T'); END;

Hi,
Please use the create_entailment API.
As far as temp tablespace goes, please create a bigfile temp tablespace. You can follow Slide #36 of the
following document.
