I am trying to index image signatures (Using version 9.2 ), but I get the following error report:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-01658: unable to create INITIAL extent for segment in tablespace ORDIMAGE_IDX_EXTBS_2

Here is the code i am using when i get the error(s).
stmt.execute("CREATE TABLESPACE ordimage_idx_extbs_1 DATAFILE 'G:\\Dipl_testdaten\\Bild\\ordimage_idx_extbs_1.db f' SIZE 1M REUSE");

stmt.execute("CREATE TABLESPACE ordimage_idx_extbs_2 DATAFILE 'G:\\Dipl_testdaten\\Bild\\ordimage_idx_extbs_2.db f' SIZE 1M REUSE");

CREATE TABLE bildtable_extern_signature(bild_id int PRIMARY KEY not null, bild_signature ORDSYS.ORDImageSignature);

Images are stored in another table.

CREATE INDEX extidx ON bildtable_extern_signature(bild_signature) INDEXTYPE IS ORDSYS.ORDIMAGEINDEX PARAMETERS('ORDIMAGE_FILTER_TABLESPACE = ordimage_idx_extbs_1, ORDIMAGE_INDEX_TABLESPACE = ordimage_idx_extbs_2');

Any ideas to what migth be the problem?
I would really appreciate any help here!

thank you very much and greeting from germany!
