Multinode installation of Oracle E-Business Suite R12.1 on OEL 6.4

Knowledge Base > Oracle Applications > Multinode installation of Oracle E-Business Suite R12.1 on OEL 6.4

in Oracle Applications

This document provides step by step instructions to install Oracle E-business suite release 12.1 on multi nodes running Oracle enterprise linux 6.4 64-bit operating system on x86-64 hardware architecture.

Refer the following document for installating Oracle Enterprise Linux 6.4 64-bit  operating system, “Installation Of Oracle Enterprise Linux 6.4″

Introduction:

The following document describes multinode installation of Oracle E-Business Suite, with multiusers, meaning that the database, all product directories and AD core directories, and all servers are installed and database tier and application tiers are owned by different users, and some services of application reside on another node. This provides improved manageability, scalability, and performance.

Prerequisites:

  • Disk Space requirements: File System Space Requirements for Standard Installation are shown below,

                                    Node                                                             Space Required

Applications node file system                                                        35 GB

Database node file system (Fresh install)                                   55 GB

Database node file system (Vision Demo Database)                208 GB

Stage area(unzipped files)                                                             47 GB

  • Edit ‘/etc/hosts’ file and add the hostname in the below shown format

ebs_inst_multinode_01(a0)

 

 

  • Edit the /etc/sysctl.conf file and configure the kernel settings as shown below. After editing the file, use the “sysctl -p” command or restart the system to invoke the new settings.

kernel.shmall = 2097152

kernel.shmmax = 429496729

kernel.shmmni = 4096

kernel.sem = 256 32000 100 142

fs.file-max = 131072

net.ipv4.ip_local_port_range = 10000 65000

kernel.msgmni = 2878

kernel.msgmax = 8192

kernel.msgmnb = 65535

net.core.rmem_default = 262144

net.core.wmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_max = 262144

  • Edit the /etc/security/limits.conf file and change the existing values for “hard” and “soft” parameters as below. Restart the system after making changes for the new values to take effect.

* hard nofile 65535

* soft nofile 4096

* hard nproc 16384

* soft nproc 2047

  • Two Domain Name System (DNS) resolver parameters (timeout and attempts) are set by default to low values when the operating system is installed. These low values may cause attempted network connections to an Oracle database to fail. Add or update the following entries to these minimum settings in the /etc/resolv.conf file on each server node.

options attempts:5

options timeout:15

ebs_inst_multinode_01(a1)

  • Oracle has released an E-Business Suite Pre-Install RPM (available on ULN and public yum) that includes all required rpms for both the application and database tiers of an R12 installation. If you are not using the pre-install rpm, the following packages are not part of the OS distribution media and must be downloaded and installed separately and installed manually using yum utility on the application tier.

  • Create users and assign default groups as shown below. ‘oracle‘ user is the owner of database tier and ‘applmgr‘ is the owner of application tier and these users belong to ‘dba’ group. We follow these notations through out the installation process. Also create required directories and change permissions as shown below.

Creating staging area:

  • Download E-business suite from www.oracle.com and create staging area by unzipping each file in the following order.

$ unzip -d /u01/ebs <zip file name>
