Preparation of the Servers
! Setup of the Servers include:
– Setting up network connections
! Public and private with switch
– Setting up shared storage for all servers
! Shared storage required
– Setting up the OS image – here OL 6.4
! Suggestion:
– Use cloning to deploy OS images fastervixencomet

Preparation of the Servers
! Recommendations:
– Use OL 6.4+ UEK
– Use the Oracle preinstall package
! Available for
– Oracle Database 11g Rel. 2
– Oracle Database 12c Rel. 1
– Additional steps to perform after using the
pre-install package for an Oracle RAC cluster:
! Add a “grid” user & “dba” group
! Align UIDs / GUIDs across servers
! Set SELinux to “permissive”, if possible
! Check large / huge pages settings
Kernel and Oracle preinstall package
[root@dasher ~]# uname –a
Linux dasher 2.6.39-400.17.1.el6uek.x86_64 #1 SMP Fri Feb 22

! Standard Cluster
! Typical Installation

! Oracle Flex Cluster:
– The new standard for flexible
resource management in the cluster
! Use it as demand requires it
! Inherits all Flex ASM HA capabilities
! Will support more use cases in future
– Efficient High Availability and
resource management across tiers
! Lightweight cluster stack on leaf nodes
– Benefit from virtualization and
physical deployments in one cluster

Install Oracle Grid Infrastructure 12c
For now, “Standard Cluster” is the default given the preselection
! Oracle Flex Cluster
– Can consist of only HUB-nodes
! If a Leaf-node has access to shared storage,
it can perform a role change to a HUB-node
– A Standard Cluster can be converted to a
Flex Cluster at any time after the installation
! Once a cluster is configured as a Flex Cluster
this configuration is irreversible without a re-
configuration of the cluster.
! Recommendation:
– An all-HUB-node Flex Cluster behaves the
same as a Standard Cluster using Flex ASM.
– Either can be used, but if in doubt, you can
choose standard Cluster and convert later.
Copyright © 2013, Oracle and/or its affiliates. All rights reserved.14
Install Oracle Grid Infrastructure 12c
Step 4: Do not accept the default – choose “Advanced Installation”
! Typical Installation
– Does not provide an option to use “Flex ASM”
– Does not provide an option to create the “Mgmt
DB / Grid Infrastructure Management Repository”
! Enhancement Requests for later
releases have been filed already
! Advanced Option
– Recommended for all configurations

“Advanced Installation” – SCAN & GNS requirement
! Recommendations:
– SCAN remains to be required for the cluster
– Choose cluster-specific unique SCAN names
– OUI will try to enforce it as much as possible
! http://www.oracle.com/technetwork/products/
clustering/overview/scan-129069.pdf
– Choose “Configure GNS” if:
! You want to use dynamic IP management
(DHCP assigned / IPv6 Stateless Address
Autoconfiguration) for client connectivity
– In this case, GNS requirements remain as
with previous version for standard cluster
Copyright © 2013, Oracle and/or its affiliates. All rights reserved.16
Install Oracle Grid Infrastructure 12c
“Advanced Installation” – Network Interface Usage
! Recommendations:
– Use “Redundant Interconnect Usage” feature
! Bonding can be used underneath if required
! MOS notes explain further configuration – e.g.:
– MOS note 1210883.1 - 11gR2 Grid
Infrastructure Redundant Interconnect
and ora.cluster_interconnect.haip
• It is recommended to align the
ASM network with the private
interconnect.
• Using different subnets for the
private interconnect is required.

“Advanced Installation” – Grid Infrastructure Management Repository
! Grid Infrastructure Management Repository (GIMR)
– A Single Instance Oracle Database 12c
– It will be installed on one of the nodes
! It is managed as a failover database
– It contains the Cluster Health Monitor (CHM) data
– It is stored in the first ASM disk group created
– As part of the configuration, Quality of Service
Management (QoS) required resources are
added to the cluster configuration (e.g. OC4J)
! Recommendation: configure the GIMR!
Copyright © 2013, Oracle and/or its affiliates. All rights reserved.18
Install Oracle Grid Infrastructure 12c
“Advanced Installation” – Storage Options
! For Standard Cluster Installations
three storage options are available:
1. Standard ASM
! ASM configuration as known
from previous releases
2. Oracle Flex ASM
! Recommended option available
with Oracle Grid Infrastructure 12c
– Flex Cluster requires Flex ASM
3. Shared File System
! Alternative

– Use Oracle Flex ASM for storage
! For better HA of database instances
! Reserve per-node spare memory

“Advanced Installation” – Create ASM Disk Group
! Recommendations:
– Create Infrastructure Disk Group (DG) first
! Use it to host OCR / Voting Disk
– Choose Redundancy accordingly
– Normal (+) redundancy is recommended
– Create Data and FRA disk groups
post installation and as required.
! Optional: Use it to host shared DB homes
by creating an ACFS file system on top of it
– http://www.oracle.com/technetwork/products/cloud-storage/
oop-patching-of-acfs-shared-oh-1885763.pdf
– ADVM volumes can be of lower
redundancy than the underlying DG

Create an Oracle RAC Database
A few tips and tricks…
This is the default…,
but not recommended
! Recommendations:
– Use a different disk group than the “database file
location”-disk group as the Fast Recovery Area.
– Automatic Storage Management (ASM)
recommendation remains unchanged
! Use it for any current production database
! New in Oracle Database 12c:
ACFS can be used to host database files
– Use ACFS for database files, if you want to
! manage “all data” on a file system
! use advanced functionality such as

Post-Install Steps
Check your environment regularly using CVU and RACcheck
#CVU is run regularly by default
[GRID]> srvctl status cvu
CVU is enabled and running on node comet
! CVU is run regularly as part of the GI stack
! Use RACcheck - RAC Configuration Audit Tool
– For details see MOS note 1268927.1
– New features in 2.2.2 include:
! Execution as the root user for sysadmin
profile e.g. ./raccheck -profile sysadmin
! RACcheck daemon feature to automate
execution of RACcheck non-interactively
at predefined interval
! Support for Solaris Sparc 11
! Upgrade best practices for 11.2.0.3, 11.2.0.4
and Oracle Database 12c
! Standard health check is now
included in post upgrade
