A WORD ABOUT THE CLOUD
-
Copyright 2016 Accenture All rights reserved. | 5
CLOUD IS ASSUMED:ITS NOT A QUESTION OF IF, BUT WHEN
Challenges exist for enterprises
Every enterprise starting point is different
Questions to ask What business problem are you trying to solve
with a
cloud implementation? How many people does this problem affect
in your
organization? How are you currently solving this problem? Has a
budget been established to solve this problem with
cloud? How are you going to divorce your cloud partner if
you
are not happy?

How it really is
Optimistic view: It is broken only on one side!
What you want to avoid
How your boss expects you to fix it

WHY A DB HEALTH CHECK?
Proactively looking for problems before they manifest
Looking for opportunities for improvement
To use as baseline before an upgrade or migration
Before moving to a new platform
If having performance, stability or scalability issues
Checking for cloud readiness

GATHERING STATISTICS For most of the objects, gathering stats
once a week is enough
If there are volatile objects, gather stats only for those
objects
Supported ways: using Gather Schema Statistics concurrent
program or FND_STATS Dont use DBMS_STATS directly for EBS objects
(because FND_HISTOGRAM_COLS)
Consider using GATHER_AUTO option Modification threshold
defaults to 10%, but can be changed Stats will be gather on objects
that have %DML > 10% of (total number of rows)
Consider using Auto Sample Size In DB 11g and 12c, Auto Sample
Size is the default Uses new hash algorithm that Oracle says that
is almost as good as 100% sample size
Remember of Data Dictionary and Fixed Objects stats
