QUESTION POSED ON: 25 July 2005
I would like to know if there are any APIs available in Oracle Enterprise Manager to find out details of a process. For example, if I know that my SAP program is running slow on my Oracle database, I would like to pass the process ID or program name to an API to get detailed information such as whether it is waiting on a locked resource or doing a full table scan, etc.

EXPERT RESPONSE
You don't need an API to Enterprise Manager to get this information; just query the dynamic performance view V$SESSION (the source of the data displayed by Enterprise Manager). It contains the client machine name, OS username and program being executed; once you have identified the Oracle session corresponding to the operation of interest, you can find out what it's waiting on ( V$SESSION_WAIT in versions previous to 10g, V$SESSION in 10g), what SQL it's executing (in V$SQLTEXT) and so on.
