REM Queries for Design Capacity Analysis
REM session_activity QUERY accidentally overwritten, get from old backup
----------------------------------------------------------------------------------------------------
REM Script capacity_analysis.sql
REM Created 09/27/2015
REM Last Modified 10/23/2015
REM Author Michele Coopersmith, Kellogg Company
REM Purpose Provide capacity info for Oracle databases prior to migration or upgrade.
REM Everything you wanted to know about your Oracle databases but were afraid
REM to ask.
REM Description Provide general configuration information for an Oracle database,
REM including sizing, tablespace names, types of objects, SGA size,
REM RMAN backup history, log mode, character set, etc.
REM Caution Some of the queries may not work in lower versions; these errors
REM can be ignored.
REM Mods check for compression - added 10/23/2015
REM check for TDE (encryption) - added 10/23/2015
REM Modes to be Added check for db scheduler jobs
