installation
4.3.2 Oracle Database 12c Pre-Installation Setup
The database nodes come pre-installed with OL 6.5 running UEK3 (3.8.13-44). To make
integration of Dell hardware and Oracle Database software seamless, the Oracle Database
12c’s preinstall utility has been customized to eliminate many of the manual steps
necessary to correctly setup the environment. This utility modifies many settings, including
but not limited to:
 Modify kernel parameters and boot settings per Oracle’s recommendations
 Add Oracle recommended module options
 Create special users with specific groups and permissions for Oracle Database
12c’s management
To supplement the Oracle Database 12c’s preinstall utility, an additional customized
deployment utility is used. This utility builds on top of the preinstall utility, and takes
additional steps to ensure that the environment is setup properly. Some of the steps
include:
 Disable SELinux (optional)
 Create additional users/groups/permissions for Oracle’s Grid Infrastructure
 Create base directories and permissions for the Grid/Database installation
 Install the necessary RPMs needed for Oracle Database 12c
4.3.3 Shared Storage Volume Partitions
With DAAD not being a traditional spinning disk based storage, but being an extremely fast
all-flash based storage array, there are no performance implications on putting all Oracle
database functions across only two ASM disk groups – one for OCR and Voting Disks
(VDs), and the other for data files, Flash Recovery Area (FRA), REDO log files, etc. As a
result, the eight storage volumes that are pre-configured and assigned to the database
nodes are pre-partitioned at the OS level and presented as raw disks these various Oracle
database functions.
Each of the eight 1.5 TB DAAD volume gets two partitions - one 15 GB and the other
spanning rest of the disk i.e. 1485 GB. Thus, DISOBA solution provides and is configured
with the following shared storage at the database node level:
1. Eight 15 GB partitions or disks, for a total of 120 GB, three of which are used for
OCR and Voting Disks, and the rest of which are free to use for additional storage.
