Создать индекс с помощью url_datastore

Question

Я должен создать индекс с параметром URL_DATASTORE в oracle 11, но когда я пытаюсь создать этот индекс, oracle возвращает мне эту ошибку

create index IDX_IT on informazioni_testi(
indextype is ctxsys.context 
parameters ( 'Datastore CTXSYS.URL_DATASTORE' );

Error starting at line 1 in command:
create index IDX_IT on informazioni_testi(url) 
indextype is ctxsys.context 
parameters ( 'Datastore CTXSYS.FILE_DATASTORE' )
Error at Command Line:1 Column:13
Error report:
SQL Error: ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
