AIA FP 2.5 with O2C2 and DTR PIPs on Oracle Database Server 11.1.0.7 generat excessive database and CPU load.

Using an AWR report you determine that the top 5 offending SQL statements are the same statement executing in different operating system processes. The 5 processes continuously toggle between ACTIVE and INACTIVE.

The SQL statement is the following:

select * from ESB_group_status where destination_system_guid='345F1FC1250F11DE8F6A458EE886031C' and error=0 and lockConId='NONE' and (service_guid, group_id) in (select service_guid, group_id from esb_message_map where status=0) order by lockTime for update
