Requirements: How to derive the OS process ID of its OWN Oracle session? Assumption is that we have access to V$PROCESS. In 10g, I solved it this way: From userenv('PID') this get mapped to the PID field of V$PROCESS. So I just derived the OS process ID (which is in the V$PROCESS.SPID field) by searching through V$Process for the corresponding USERENV('PID'). But in 9iR2, userenv('PID') is not a valid parameter. So what is the equivalent parameter to be passed to userenv()? Thank you very much. -- //www.freelists.org/webpage/oracle-l
