Query the Process ID and SQLTEXT area

Here's how to view the details of each session and the I/O stats per session, then use one of the SIDs to query any SQL held in the SQLAREA. The output is spooled to a file.

The ideas for this script are ages old, and bits come from several sources including myself. I have embellished various parts to make them more presentable. I don't think anyone can claim ownership of this sort of stuff anyway.
