Oracle Applications 11i Single-Node Installation on Linux   

This article describes the single-tier installation of Oracle Applications 11i (11.5.10.2) on RedHat Linux 4 (CentOS 4.4)  

• Hardware requirement

• Software download

• Linux installation

• Staging the Oracle Application

• Preparing the Linux environment for the installation

• Installing the Oracle Applications 11.5.10.2

    Hardware requirement

    For this installation type is good to have one personal computers/ laptop with this configuration:

•  Pentium 4 Processor 

• 1Gb RAM

• 200 Mb Hard Disk

• 1 network card (Linux compatible). ( D-Link DFE-530 TX network card could be used )

    Software download

    Linux installation

    I suggest a full Linux installation even if there are some components which are not necessary to spend less time and to have all we need for the Oracle Applications installation. I suggest also on the both computers to create 1Gb tmp directory and a 2Gb swap directory.   

    Staging the Oracle Application

    Oracle Applications are downloaded in a compressed format, so these files cannot be used directly for the installation. For this reason the files must be unzipped in the same directory to create the staging directory:

    For that we have to:

•  create a directory which can be read/ write by all users for the download ( for example /media/usbdisk/download );

•  create a directory which can be read/ write by all users for the staging ( for example /media/usbdisk/APPS0 ); 

•  unzip all the Oracle Application zip files in the staging directory ( /media/usbdisk/APPS0).  These directories must be created: oraAppDB, oraApps, oraDB, oraiAS, startCD. 
  

    If we have the Oracle DVDs / CDs with the Oracle Applications installation kit, we have to follow the next steps to set up a staging directory:

• insert the Start Here disk in the CD-ROM (DVD-ROM) drive

• $ cd /media/cdrecorder/Disk1/rapidwiz

• run the AutoStage script: $ perl adautostg.pl

• set up the stage area directory (If you chose  /media/usbdisk/APPS0 as the top-level directory, the staging directory will be  /media/usbdisk/APPS0/Stage11i)

• indicate the components to be staged

    Preparing the Linux environment for the installation

    In order to have a Linux environment ready for the Oracle Applications 11i single-tier installation we have to:

    1) create the oracle Linux user account. The oracle user must be a member of the dba group as well

    2) create /APPS directory (owned by oracle:dba) 

    3) install compatibility files for running Oracle on RHEL 4

        rpm -ihv compat-oracle-rhel4-1.0-5.i386.rpm
        rpm -ihv compat-libcwait-2.1-1.i386.rpm

    Installing the Oracle Applications 11.5.10.2

    The Oracle Applications 11i single-node installation is done with the oracle account. 

    1. Start the installation on the database tier:

      #  cd /media/usbdisk/APPS0/Stage11i or in my case /media/usbdisk/APPS0/11i_Unzipped/

      #  cd startCD/Disk1/rapidwiz

      #  ./rapidwiz

     Here are the windows which appears and the responses we have to choose:

Select "Next".

Check "Use express configuration" (The Oracle Applications settings will be done automatically).

Select "Next".

Select the base directory as shown on this screen.

Select "Next".

Enter the path for the configuration file as shown on this screen.

Select "Next".

Select "Next".

Select "Next".

Select "Yes".

Wait until the installation will complete.

 If the installation looks not to advance that could be verified by looking to the CPU utilization or/ and disk activity (io). vmstat utility is used for this.

Select "Next".

Press "Connect to Oracle Applications 11i" to test if the Oracle Applications are running.  Press "Finish".

Now the installation is done.

2. Make the libjavaplugin_oji.so available for Firefox browser (if used)

cd /usr/lib/firefox-1.5.0.3/plugins
ln -sf /APPS/viscomn/util/java/1.4/j2sdk1.4.2_04/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
