Goal
This script allows the user to take the 'Memory Utilization of Subpool X' section from an ORA-04031 trace file and store
into the database so that simple queries can be run against e.g. to see the highest memory allocations, to determine the
total number of bytes in the subpool etc.
The methodology is based on creating a simple table under the SCOTT account (any appropriate schema can be used),
that is then populated via SQLLDR.
Knowing the largest memory allocations in a subpool or knowing the number of bytes within each subpool (where >1 is in use)
can prove useful for analyzing to known/potential issues but detailed analysis is not possible from the script itself.
