Two Management Styles

for Oracle RAC

• Administrator Managed

– Specifically define where the database should run with a list

of servers

– Define where services should run within the database

• Policy Managed

– Define resource requirements of workload

– Enough instances are started to support workload

requirements

– Goal: To remove hard coding of a service to a specific

instance or node

Server Pool

• Logical division of the cluster into pools of servers

• Applications (including databases) run in one or more

server pools

• Managed by crsctl (applications), srvctl (Oracle)

• Defined by 3 attributes (min, max, importance) or a

defined list of nodesdefined list of nodes

– Min- minimum number of servers (default 0)

– Max – maximum number of servers (default 0 or -1)

– Importance – 0 (least important) to 1000

Cluster Managed Services with Server

Pools

• One to one mapping

– (ie. a service can only run in one server pool )

• Services are • Services are

– uniform (run on all instances in the pool)

– singleton (runs on only one instance in the pool)

information about new options included

Upgrade Length• How long will the upgrade taketo complete?– Independent of:

– Size of the database

– Used datatypes

– Dependent on:

– The number of objects needing upgrading and recompilation

– Thus: the number of installed options/components– Thus: the number of installed options/components

– The number of synonyms – they‘ll get recompiled

– Valid and non-stale data dictionary statistics

– At a very low rate:

– Number of datafiles

– Size of redo logs

Documentation• Documents to study before you start?

Guidelines

• Never ever change to many system components at once!

• Document all changes detailed and clearly into a change log!

• Always (!!!) use real word data for testing!

• Don't underestimate the test efforts. Reserve enough time and

resources for testing.

• ALWAYS collect as much performance data BEFORE the

upgrade will be started!!upgrade will be started!!

• Create a fallback strategy!

• PLEASE test your fallback strategy - does it really work??

• Please remember:

Upgrade never has been easier - but you still have to test!!!
