We started to use oracle AQ and spring-jms and it works fine. But when ~1000 messages goes though my queue BUS\_BILLING\_RECEIVE\_QT there is 110000 selects I wrote below: 

```
select /*+ INDEX(TAB AQ$_BUS_BILLING_RECEIVE_QT_I) */ tab.rowid, tab.msgid, tab.corrid, tab.priority, tab.delay, tab.expiration , tab.retry_count, tab.exception_qschema, tab.exception_queue, tab.chain_no, tab.local_order_no, tab.enq_time, tab.time_manager_info, tab.state, tab.enq_tid, tab.step_no, tab.sender_name, tab.sender_address, tab.sender_protocol, tab.dequeue_msgid, tab.user_prop, tab.user_data from "WORKLOAD_PROD"."BUS_BILLING_RECEIVE_QT" tab where q_name = :1 and (state = :2 ) order by q_name, state, enq_time, step_no, chain_no, local_order_no for update skip locked

```

It causes performance problem...
May be sombody knows which produces this select, and how I can reduce this enormous amount?
