Oracle Applications Release 12 Installation on Cent OS 5 (32/64-bit)

I have successfully installed oracle applications 12.1.1 after a few trial runs in 64bit Cent OS 5. I had the instructions for RHEL 5 or 32-bit Cent OS 5. Once I started on 64-bit, as usual, my run did not make it. Finally, metalink help was very handy as the version 12.1.1 is new (as of writing this post). Please note that there is a difference between 32-bit & 64-bit version and the bug fix details are given. Here are the steps for you to follow.

Fully qualified name and /etc/hosts setup is important pre-step!

Operating Systems Requirements

Kernel Requirements

Since Cent OS is made on RHEL, we can install oracle applications over Cent OS 5.0.
Cent OS 5 –> 2.6.18-92.1.22.el5
To determine version, enter: $ uname – r

Create a staging area for the Oracle Applications:

This is from the meta link, I do not know the nuance of it. My system has better setting with 4 GB RAM. Hence, I left it as it is. Add the following lines to the /etc/sysctl.conf file:

JDK 5.0 Requirements

JDK is bundled with Oracle Applications.

Software Requirements

• ar
• gcc
• g++
• ld
• ksh
• make
• X Display Server

Eg : which ar, which gcc, xclock

Kernel Settings

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

Parameter Value

kernel.semmsl 256

kernel.semmns 32000

kernel.semopm 100

kernel.semmni 142

kernel.shmall 2097152

kernel.shmmax Half the size of the physical memory (in bytes), and at least 2147483648

kernel.shmmni 4096

kernel.msgmax 8192

kernel.msgmnb 65535

kernel.msgmni 2878

fs.file-max 65536

net.ipv4.ip_local_port_range 1024 65000

net.core.rmem_default 262144

net.core.rmem_max 262144

net.core.wmem_default 262144

net.core.wmem_max 262144

Domain Name System (DNS) Resolver Parameters

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. If this happens, 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

Verifying Host Names

Use the following to verify host name settings:

Verify that the /etc/hosts file is formatted as follows:

1. 127.0.0.1 localhost.localdomain localhost
   
   <ip_address> <node_name>.<domain_name> <node_name>

2. Verify that the /etc/sysconfig/network file is formatted as follows:

   HOSTNAME=<node_name>.<domain_name>

3. If the /etc/sysconfig/networking/profiles/default/network file exists, remove it.
4. If you changed any files in the previous steps, restart the system.

Modifying the Number of Open File Descriptors

Open the /etc/security/limits.conf file and change the existing values for “hard” and “soft” parameters as follows. Restart the system after making changes.

Note: If the current value for any parameter is higher than the value listed in this document, then do not change the value of that parameter.

  * hard nofile 65535
  * soft nofile 4096
  * hard nproc 16384
  * soft nproc 2047

Net Service Listeners in Multi-user Installations

Net Service Listeners use the /var/tmp.oracle directory to store temporary files. To give all users in a multi-user installation write privileges, update /var/tmp/.oracle with 777 permissions:

$ chmod 777 /var/tmp/.oracle

Create Users and Groups

groupadd dba

useradd -g dba oracle    ( db tier )

useradd -g dba applmgr ( apps tier )

Creating the Stage Area Directory

Follow these steps to set up a stage area installation:
Log in as the operating system user with sufficient privileges to mount, unmount, and eject the DVD. This user must also have write privileges to the stage area that you set up.
Insert the Start Here disk in the DVD-ROM drive.
Mount the DVD (conditional).
If your system runs on a UNIX platform, and if you do not use AutoMount, you must mount the Start Here disk now.
Verify software version (perl).
You must have perl 5.0053 or higher installed, and it must be in your PATH. Use the following commands to identify the perl version and its location. The command is the same for both UNIX and Windows platforms:
perl -v

On UNIX, set the environment variable DISPLAY to an active and authorized display.

Run the adautostg.pl script.
UNIX:
$ cd
$ perl /mnt/cdrom/Disk1/rapidwiz/adautostg.pl

Starting Rapid Install
Once the stage directory is created, start Rapid Install as described in the following section.
UNIX:
Example
$ cd /u01/Stage12/startCD/Disk1/rapidwiz
$ ./rapidwiz

Proceed with the wizard

Proceed with the wizard

Select Accept if you want to install Oracle Configuration Manager ( Not Mandatory )

if OCM Selected , then you will have to fill up CSI, Metalink Account

For Single Node fresh Installation, Select Create a new configuration,

If Multi Node Installation, and if this was the second node then you have to load

the configuration file created from the first node ( usually found in /tmp )

Select Port Pool

Fill Database Node Configurations

Select the Licensing

Select Additional Licensing if reqd.

Select Country Specific Functionalities

Select Internationalization Settings

Select Primary Application Node Settings

The services provide the following functionality, which differs significantly from
Release 11i and also uses new terminology:

This Service Group: Supports:
Root Services Oracle Process Manager (OPMN)

Web Entry Point Services HTTP Server

Web Application Services OACORE OC4J
Forms OC4J
OAFM OC4J

Batch Processing Services Applications TNS Listener
Concurrent Managers
Fulfillment Server

Other Services Oracle Forms Services
Oracle MWA Service

Applications nodes should have services enabled as follows:
. For Web and Forms services: Root Services, Web Entry Point Services, Web Application Services, and Other Services
. For Concurrent Processing services: Batch Processing Services
As an example, consider a two-node installation where you wish to deploy the Applications database and Concurrent Processing services on Server A, and Web
and Forms services on Server B.
. On Server A, you would select Batch Processing Services.
. On Server B, you would select Root Services, Web Entry Point Services, Web Application Services, and Other Services.

In terms of ORACLE_HOME creation, the result will be that:
Server A has an ORACLE_HOME for the 10g R2 Applications database, plus an ORACLE_HOME for Application Server 10.1.2, and an ORACLE_HOME for Application Server 10.1.3.

Server B has an ORACLE_HOME for Application Server 10.1.2, and an ORACLE_HOME for Application Server 10.1.3.

If your installation if multi-node then you can specify the other server configuration here.
