How can I determine, whether there are any statistics relating to fixed objects?
As of Oracle 10g, we recommend that you use fixed object statistics (refer to Note 838725). You can check whether these statistics have been created or not as follows: SELECT TABLE_NAME FROM DBA_TAB_STATISTICS WHERE LAST_ANALYZED IS NOT NULL AND OWNER = ‘SYS’ AND TABLE_NAME LIKE ‘X$%’; If the query returns X$ tables, then fixed object statistics exist.
