My Dell desktop:
[root@erp RPMs]# cat /proc/cpuinfo model name : Intel(R) Pentium(R) 4 CPU 2.80GHz cpu MHz : 2793.022 cache size : 512 KB [root@erp RPMs]# cat /proc/meminfo MemTotal: 2073404 kB ...
kernel-smp-2.6.9-42.0.3.EL.i686.rpm and apply with:
$ rpm -ivh kernel-smp-2.6.9-42.0.3.EL.i686.rpm
The kernel should look like this:
root@erp RPMs]# uname -a Linux erp.itskills.com 2.6.9-42.0.3.ELsmp #1 SMP Thu Oct 5 15:04:03 CDT 2006 i686 i686 i386 GNU/Linux
Before beginning the installation, you must confirm that you have these utilities:
X Display Server (VNC)
To check if these are available, use
which; for example:
Make sure that the following kernel setting are in effect. Update
/etc/sysctl with the following parameters, and then run
kernel.semmsl = 256 kernel.semmns = 32000 kernel.semopm = 100 kernel.semmni = 142 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.msgmax = 8192 kernel.msgmnb = 65535 kernel.msgmni = 2878 fs.file-max = 65536 net.ipv4.ip_local_port_range = 102465000 net.core.rmem_default = 262144 net.core.rmem_max = 262144 net.core.wmem_default = 262144 net.core.wmem_max = 262144

/etc/security/limits.conf for “hard” and “soft” parameters.

I used the
oracle user as the owner of both APPS and database.
Downloading 12i Software
Download 12i (12.0.4) from edelivery.oracle.com.
Here are the disk details required.
- Space required for download 12i: 34.1GB
- Space required for the actual install (Fresh Database): 65GB
- Space required for the unzipped 12i Software: 40GB
This is what I did. I had two disks on the PC—40GB and 250GB, and I had a Lacie 500GB Firewire Drive. I used the 40GB for the dual setup (Windows and Linux), and mounted the 250GB as
/250G for the 12i software, using an ext2 filesystem. I mounted the Lacie Drive as
/500GB for the actual install.
Begin the installation
Once you have unzipped the 12i Software, make sure the following is set up . . .
oracle:dbais the owner of the directory where you are installing
oracle:dbaowns the software directory
. . . and then you can start the installation.
oracle:dba, start a vnc server:
$ vncserver :2
Logmin to vncviewer:
$ vncviewer :2
xclock/code> If you get a clock, you are good to start. Navigate to the staging area.
$ /250G/startCD/Disk1/rapidwiz $ ./rapidwiz
Congratulations, you now have your 12i instance. Tempted to log in? Why not!
You will require the password for SYSADMIN. Oracle never asked us for that, so I had to wait, and ask here and there. And then this worked:
sysadmin. Yes, that’s the password for SYSADMIN. And the password for apps is
apps. So log in and scroll through the new windows of your own 12i.
You may wonder why I used
oracle:dba for both apps and database. I did so because I intended to used to this machine for other set-ups too—10g, 11g, OID, etc., and so I wanted to keep it simple as the 12i is on Firewire. It will be mounted every time machine boots, so it’s easy to do this:
$ chown -R oracle:dba /500GB
Create a env file for 12i, and log in as
.12i.env and just add the following two lines:
./500GB/12i/db/tech_st/10.2.0/PROD_erp.env . /500GB/12i/tech_st/10.2.0/PROD_erp.env
Now invoke the env file and play around with the file systems.
