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

• 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 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

    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

[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

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
