Hi List, we need to troubleshoot a problem around excessive dynamic sampling and library cache locks at my client. Probably we are facing a bug 14542720. For the moment I'm looking for a way of how to match the sql_id's that have used dynamic sampling during parse to the sql_ids of the dynamic sampling itself (those queries with the SELECT /* OPT_DYN_SAMP */ ...) any idea? TIA Mathias
