Goal
This script is intended to provide trend analysis information in the form of reports which would be used by the DBA to identify any sessions that over time use significantly more UGA and/or PGA memory than their peers by generating a snapshot report of the current values of UGA and PGA memory usage per RDBMS session as well as the maximum values of UGA and PGA memory usage since the time when each of the current RDBMS sessions started. For re-occurring ORA-04030 errors or ORA-04036 errors this script can also be a useful diagnostic tool to find out what RDBMS sessions (if any) use significantly more PGA than their peer RDBMS sessions.
