Dear DBAs, I could not see the actual statistics in a "SET AUTOTRACE ON" session though I have the following set on my server: SQL> show parameter stat NAME TYPE VALUE ------------------------------------ ------- ------------------------------ timed_os_statistics integer 0 timed_statistics boolean TRUE And, I tried enforcing the same Alter session set timed_statistics=3Dtrue; select * from xyz; .. .... Statistics ---------------------------------------------------------- 0 recursive calls 0 db block gets 0 consistent gets 0 physical reads 0 redo size 0 bytes sent via SQL*Net to client 0 bytes received via SQL*Net from client 0 SQL*Net roundtrips to/from client 0 sorts (memory) 0 sorts (disk) 570309 rows processed Am I missing something? Environment: HP-UX B.11.11 Oracle 8.1.7.4 Thanks, Arul. -- //www.freelists.org/webpage/oracle-l
