Oracle Applications 11i Multi-Node Installation on Linux   

This article describe the installation of Oracle Applications 11i (11.5.10.2) on RedHat Linux 4 (CentOS 4.4)  

 

 

    Hardware requirement

 

    For this installation type is good to have 2 personal computers 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 )

    Also a switch and 2 network cable are necessary in order to connect the 2 computers. 

 

 

    Software download

 

Software Link
Oracle Applications http://edelivery.oracle.com/
CentOS 4 (a Red Hat 4 Linux version) http://isoredirect.centos.org/centos/4/isos/i386/
Compatibility files for running Oracle on RHEL 4:

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

    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 multi-tier installation we have to:

 

    1)  connect the 2 computers (PC1 will be the database server, and PC2 will be the server which will have the middle-tier installed on):

   

         on PC1 ( the database server):

         -  edit /etc/hosts and add the following lines:

            192.168.1.201   APPS_svr.localdomain      APPS_svr
            192.168.1.202   DB_svr.localdomain          DB_svr

         -  set the network card with 192.168.1.202 IP address and Mask: 255.255.255.0

        

         on PC2 ( the applications/ middle-tier server):

         -  edit /etc/hosts and add the following lines:

            192.168.1.201   APPS_svr.localdomain      APPS_svr
            192.168.1.202   DB_svr.localdomain          DB_svr

         -  set the network card with 192.168.1.201 IP address and Mask: 255.255.255.0

      2)  test the connection between the 2 computers (on each computer):

 

[root@localhost ~]# ping -c 2 DB_svr
PING DB_svr.localdomain (192.168.1.202) 56(84) bytes of data.
64 bytes from DB_svr.localdomain (192.168.1.202): icmp_seq=0 ttl=64 time=0.109 ms
64 bytes from DB_svr.localdomain (192.168.1.202): icmp_seq=1 ttl=64 time=0.113 ms

--- DB_svr.localdomain ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1000ms
rtt min/avg/max/mdev = 0.109/0.111/0.113/0.002 ms, pipe 2


[root@localhost ~]# ping -c 2 APPS_svr
PING APPS_svr.localdomain (192.168.1.201) 56(84) bytes of data.
64 bytes from APPS_svr.localdomain (192.168.1.201): icmp_seq=0 ttl=64 time=0.038 ms
64 bytes from APPS_svr.localdomain (192.168.1.201): icmp_seq=1 ttl=64 time=0.031 ms

rtt min/avg/max/mdev = 0.031/0.034/0.038/0.006 ms, pipe 2

    3) create the oracle user on the database server and the applmgr user on the applications/ middle-tier server. The oracle user must be a member of the dba group as well 

 

    4) create /APPS_DB directory (owned by oracle:dba) on the database server and /APPS_MI directory (owned by applmgr:oinstall) on the applications server

 

    5) install (on both computers) the 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 multi-node installation is done with the root 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
