Owners Manual

Dell Integrated Systems for Oracle Business Analytics (DISOBA) – Owner’s Guide 1.0
 Create special oracle user with specific groups and permissions for Oracle BI
To supplement the Oracle BI 11g 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 BI Infrastructure
 Create base directories and permissions for the BI installation
 Install the necessary RPMs needed for Oracle BI 11g
4.2.3 Oracle Network Configuration
In order to minimize the needed steps taken by the customer to setup the Oracle BI
environment, DISOBA also ships with some of the network pre-configured on the OBIEE
server. The network is configured using Dell and Oracle’s best practices in mind. To keep
every possible component redundant for high availability, the public networks are each
configured in a redundant mode. To further increase redundancy, each of the 10Gb
Mellanox Ethernet cards have one link from each of the public networks to the Public
switches to reduce yet another single point of failure. By spreading both networks over
two cards, we are able to eliminate the possibility of a downed card resulting in lost
communication.
NOTE: The public network interface is not pre-assigned with an IP address and requires to
be assigned at the customer’s site.
4.3 Database Nodes (R920) Configuration
This section describes the OS pre-configuration that is applied on the database nodes to
ease the Oracle Database deployment at the customer site. The configuration is done
based on Dell and Oracle’s best practices.
Database nodes are pre-configured and optimized in the following areas:
4. Hardware configuration
5. Oracle Database 12c pre-installation setup
6. Shared storage volume partitions
7. Disk permissions setup using UDEV rules
8. Device-Mapper multipath
9. ION tuner
10. Oracle network configuration
4.3.1 Hardware Configuration
Before any software is installed, we have taken steps to ensure that the hardware
configuration is adequate to support the Oracle environment. This includes making sure
we have optimized the BIOS settings, updated appropriate firmware, used the proper RAID
configuration, and created properly sized/named partitions. Some details are as follows:
