This was presented at Oracle's 11g R2 Live seminars in June. It allowed customers and partners to view the benefits of implementing or upgrading to Oracle's latest version of it's database and Advanced Technology products such as Real Application Clusters, Real Application Testing and Enteprise Manager.
15. Database User Name :- system
Database password :- oracle
Client Oracle Home :- /u01/app/oracle/product/11.2.0/db
Client Replay Directory :- /home/oracle/rat_replay
38. 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
39. 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 nodes
– Min- minimum number of servers (default 0)
– Max – maximum number of servers (default 0 or -1)
– Importance – 0 (least important) to 1000

41. Cluster Managed Services with Server
Pools
• One to one mapping
– (ie. a service can only run in one server pool )
• Services are
– uniform (run on all instances in the pool)
– singleton (runs on only one instance in the pool)

60. Upgrade is easier!
• The upgrade to Oracle Database 11g is much easier
than any upgrades to earlier Oracle releases
• Size of Upgrade guides:
– 8.1.7 - 512 pages
– 9.0.1 - 484 pages – 111 steps for an RDBMS with 9 components
– 9.2.0 - 344 pages
– 10.1.0 - 170 pages - only 6 stepsl!!!
– 10.2.0 - 140 pages
– 11.1.0 - 186 pages - now detailed explanations and
information about new options included
61. Upgrade Length
• How long will the upgrade take
to 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
– 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
62. Documentation
• Documents to study before you start?
– Note 785351.1 – Oracle 11G R2 Upgrade Companion
– Note:837570.1 - Complete Checklist for Manual Upgrades to
11gR2
– Note: 421191.1 - Complete checklist for manual upgrades from
X to Y

64. 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!!
• 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!!!
