I do have a PL/SQL function that gets executed called many times but with different parameter values each of these times. For most invocations of this function run in a couple of seconds however some invocations of the same function run (on the same dataset) for hours with very little disk activity but high CPU.
How can I monitor the actual DB activities during such times so I may better understand what the situation truly is.
You can monitor system parameters (CPU, disk IO, memory) with standard OS-specific tools (on Unix: top, ps iostat,vmstat)
I have seen some users on this list posting some complex log/outputs, this are the kind of outputs I would like to capture and view. Where are they?
they are mostly in log files or output from EXPLAIN ANALYZE command
