I am getting this message while attempting to dequeue. Delphi 7, DOA 4.7.0.1, Oracle 10.1.0.5

My queue is created as follows:

dbms_aqadm.create_queue_table(
queue_table => 'VEGA_HTTP_QUEUE',
storage_clause => 'TABLESPACE &QUEUE_TBS',
sort_list => 'PRIORITY,ENQ_TIME',
comment => 'Vega HTTP pages queue',
multiple_consumers => FALSE,
queue_payload_type => 'RAW');

dbms_aqadm.create_queue (
queue_name => 'VEGA_HTTP',
queue_table => 'VEGA_HTTP_QUEUE');

1) What triggers it? The queue uses a RAW payload type.
2) Why the exception is an Exception type and not an EOracleError type?

Found the problem: the queue name had the wrong owner. But the exception raised is totally misleading!

We'll fix the error message. It is indeed misleading. It is not an EOracleError exception, because it is not raised by Oracle but by the TOracleObject class.

Thank you.

What about a DOAError exception for those error raised by DOA classes but not Oracle? Would simplify bug hunting - I know it could break existing code.

We'll consider it. I don't think it can break existing code though, since a DOAError would also be an Exception.
