Active reports are a new type of HTML reports showing more information than the vanilla HTML reports. Also, look and feel is really improved since the content of these reports is displayed using the same interactive UI as the one in Oracle Entreprise Manager. For more information on SQL Monitor active reports, see http://www.oracle.com/technology/products/manageability/database/sqlmonitor.html. You will find few examples there like the example below reporting on the execution of a parallel index create: http://www.oracle.com/technology/products/manageability/database/active_reports/samples/faq_create_index.html Active reports can be directly generated from SQL*Plus command line, like the regular HTML report.

Executing the report_sql_monitor function with session_id=>sys_context('userenv','sid') will return data for the most recently monitored statement by any session with the SID 102, but it won't be my current session because it hasn't executed a long running statement. It would be nice if we could add another where clause that said session_serial=>sys_context('userenv','serial#'), but unfortunately that option doesn't seem to exist. I was hoping you might know of an undocumented option. This would be handy in a number of places by the way. For example, when connected as sysdba, the audsid is not unique and so there is no way with sys_context (that I am aware of) to determine which session is actually mine if there are more than one sysdba connections. Anyway, I worked around the issue with the report_sql_monitor function by doing a subquery something like this - session_serial=>(select serial# from v$session where audsid=sys_context('userenv','sessionid')) I hope this makes sense (and the formatting isn't too bad). Hi Greg,

Thanks for the quick response. On busy systems, SID’s are frequently reused so it is necessary to specify the serial# as well to ensure that we’re looking at the correct session. Here’s an example (I hope the formatting is OK – if not have a look at a posting I just did on the subject at kerryosborne.oracle-guy.com)

So you can see that there have been many sessions with SID 102 over the last several days that executed long running statements. Executing the report_sql_monitor function with session_id=>sys_context(‘userenv’,’sid’) will return data for the most recently monitored statement by any session with the SID 102, but it won’t be my current session because it hasn’t executed a long running statement.

It would be nice if we could add another where clause that said session_serial=>sys_context(‘userenv’,’serial#’), but unfortunately that option doesn’t seem to exist. I was hoping you might know of an undocumented option. This would be handy in a number of places by the way. For example, when connected as sysdba, the audsid is not unique and so there is no way with sys_context (that I am aware of) to determine which session is actually mine if there are more than one sysdba connections. Anyway, I worked around the issue with the report_sql_monitor function by doing a subquery something like this -

session_serial=>(select serial# from v$session where audsid=sys_context(‘userenv’,’sessionid’))

I hope this makes sense (and the formatting isn’t too bad).
