Objective:

In the previous article Oracle SOA suite, webcentre Portal,  Webcentre Content, Identity Management schemas and Installation we learned about the schemas in Fusion Middleware. In this article we will learn about the configuration required for the installation of Fusion Middleware.

Fusion Middleware Installation

Supported configuration overview:-

Before we start with Installation we need to check whether the products are certified and supports the operating system where we will install Middleware stack.

• Check and verify system requirements.

• support.oracle.com -->certifications

• Excel sheet with all the certifications.

Obtained certified version of FMW from below website:

http://www.oracle.com/technetwork/middleware/fusion-middleware/downloads/index.html

Memory Requirements of operating system:-

Hardware and System Requirements:

RPMS(Red Hat Process Package Managers)

when we install some softwares on linux, there are some binaries that help the software to get installed on linux machine. Like in Windows we have DLL likewise in linux we have RPMS. we need the RPMS for database also.

Below is the list of RPMS.

Setting Open File Limit:-

• on all the Linux system, the minimum Open FIle limit should be set to 4096. Below are the commands to change open file limits:

1. Log In as Root user

2. Locate and open the following OS configuration file:

/etc/security/limits.conf

3.   Look for and modify below in limits.conf:

*soft nofile 4096

*hard nofile 65536

*soft nproc 2047

*hard nproc 16384

4.   save the changes and close the limit.conf file.

5.   If you are using Linux 6 o0r Red Hat Linux 6, locate the following operating system configuration

           file.

           /etc/secutiy/limits.d/90-nproc.conf

6.   Make sure the same values are added to the 90-nproc.conf.file; otherwise, the values in the

           90-nproc.conf.file can override the values in the limits.conf file.                       

7.   Reboot the Machine.

special startup requirements for linux 32-64 bit operating system for Oracle Universal Intaller.

1. change the value for SHMMAX to 4294967295 by including the following line in/etc/sysctl.conf:

kernel.shmmax=4294967295

2.   Activate the new SHMMAX setting by running the command:

/sbin/sysctl -p

3.   Start the Universal Installer and install the software.
