Have you looked at ORA-600 [kti_freeing_non_freeable] And ORA-4031 On Shared Pool (Doc ID 1457819.1) ? -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of GG Sent: Monday, March 17, 2014 2:46 PM To: oracle-l@xxxxxxxxxxxxx Subject: ORA-4031 "shared pool","unknown object","sga heap(6,1)","KTI SGA freea" Hi, Anyone has an idea what is the 'KTI SGA freea' allocation all about ? We've experienced ora-4031 related to this on 11.2.0.3 with latest PSU applied . So far, no idea . KGLH0 allocations sizes as well as SQLA was not an issue this time :).
