Thomas, The LAST_CALL_ET column signifies (in seconds) the last time a session did *anything*. This value is a delta offset from sysdate. So, the following query would show you the last time the session did any work: select username,logon_time,last_call_et, to_char(sysdate-(last_call_et/(60*60*24)),'hh24:mi:ss') last_work_time from v$session where username is not null You can compare this value with the "drilldown" value returned by OEM for a session. You will see that this is the value that is returned. I figured this out one by by tracing the OEM sql to see how they did this. Good Luck!

I have IDLE_TIME set to 20 in the profile and resource_limit is true. This does not time out an idle terminal. What is the meaning of the values in V_$SESSION.LAST_CALL_ET? Oracle documentation is less than illuminating. All it says is "LAST_CALL_ET NUMBER The last call". This is from Oracle9i Database Reference,Release 2 (9.2),Part Number A96536-02. Any help, examples, or stories of "how we did it" would be greatly appreciated. -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
