Well, I was afraid that you will ask me that. Monitoring is the best way to do it. There is a sys-owned table called "OBJECT_USAGE", which contains column OBJ#, which can be joined with OBJECT_ID from dba_objects and there is column "FLAGS". If bitwise and between FLAGS and 0xFFFF is non-zero, the object was used in the monitoring period. Here is the function that oracle uses to define that view: decode(bitand(i.flags, 65536), 0, 'NO', 'YES'), Of course, that is not officially sanctioned. Please, have mercy on me on 15/04.
