4.2 Database nodes configuration

This section describes the OS preconfiguration that is applied on the database nodes to

facilitate faster deployment of Oracle Database 12c at the customer site. The configuration

is done based on the best practices of Dell and Oracle.

Database nodes are preconfigured and optimized in the following areas:

 Hardware configuration

 Oracle Database 12c preinstallation setup

 Shared storage volume partitions

 Disk permissions setup using UDEV rules

 Device-Mapper multipath

 Oracle network configuration

To view the list of Dell PowerEdge servers that are supported as the database nodes in the

DISOD solution rack, see the

2.1 Database servers

section.

4.2.1 Hardware configuration

Before any software application is installed, it was ensured that the hardware configuration

is adequate and optimized for Oracle Database environment. This includes setting the

recommended BIOS settings for Oracle Databases, appropriate updated firmware, setting

the recommended RAID configuration, and creating the required partitions for the OS and

for the Oracle Database software. These configuration details are further provided below:

 System Profile and memory configuration is set to ‘Performance Optimized’ in the

BIOS settings

 Installed firmware versions on all the hardware either matches or is newer than

what was tested with

 Each database node has two 1.2 TB HDDs in RAID 1 with a global hot-spare

(1×1.2TB) configured.

 Local HDD logical volume partition configuration:

o 60 GB ‘/’ (root partition for OS)

o 17 GB swap (minimum 16 GB + 1 KB required by Oracle Database)

o Rest allocated to /u01 to be used for Oracle Database software installation

4.2.2 Oracle Database 12c pre-installation setup

The database nodes come preinstalled with OL 6.6 running UEK release 3. To make

integration of Dell hardware and Oracle Database software seamless, the preinstall RPM

for Oracle Database 12c has been customized to eliminate many of the manual tasks

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 module options as recommended by Oracle

 Create special users with specific groups and permissions required for the

management of Oracle Database 12c.
