Ready for installation of EBS R12.1.1

After the Guest Additions were enabled and the shared disk mounted succesfully I repeated the work I had done a couple of months ago:

First REBOOT (Log Out / Login as ROOT)
Now you can also copy and paste from Windows 7 to Linux

==== Required packages
Installed the remaining installed packages downloaded from
- openmotif21-2.1.30-11.EL5.i386.rpm
- xorg-x11-libs-compat-6.8.2-1.EL.33.0.1.i386.rpm

==== Kernel Settings
Added the following lines to /etc/sysctl.conf:
# lines added to /etc/sysctl.conf for installation of EBS R12
kernel.sem = 256 32000 100 142
kernel.shmmni = 4096
kernel.msgmni = 2878
kernel.shmmax = 2147483648
fs.file-max = 131072
net.ipv4.ip_local_port_range = 10000 65000
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144

- kernel.shmmax is already in /etc/sysctl.conf but with a value way to high. I commented that line out and added a new entry as you can see above. The new value
is the minimum value value for this parameter, but already more than physical memory assigned to VirtualBox.
- kernel.shmall = 4294967296 (not edited; 2097152 in [ID 761566.1])
- kernel.msgmax = 65535 (not edited; 8192 in [ID 761566.1])
- kernel.msgmnb = 65535 (not edited; same as in [ID 761566.1])

==== Domain Name System (DNS) Resolver Parameters
Added the following lines to /etc/resolv.conf
options attempts:5
options timeout:15

==== Verifying Host Names
/etc/hosts file is Ok
/etc/sysconfig/network file is Ok
No file /etc/sysconfig/networking/profiles/default/network (is Ok)

==== Modifying the Number of Open File Descriptors
Added the following lines to /etc/security/limits.conf
# Added for installation of EBS R12
* hard nofile 65535
* soft nofile 4096
* hard nproc 16384
* soft nproc 2047

System > Logout ROOT
Login as ROOT again

=== OS Library Patch for Oracle HTTP Server
Tried to do it, but this patch is at My Oracle Support only available for Linux x86.
Moreover it s replacing the file /usr/lib/ which doesn't exist at my system

=== Link to Motif library in Oracle Application Server 10.1.2 (on Oracle Linux 5 and RHEL 5 only)
unlink /usr/lib/
ln -s /usr/X11R6/lib/ /usr/lib/

=== OPMN port conflict
check use of port 6000: netstat -a | grep 6000
Not used -> no potential conflict = OK

=== Ready for installation of EBS R12.1.1
I made a snapshot in VirtualBox of this moment! You should do it too.

Last weekend I spent a lot of time on recreating a virtual disk. Last week I was already almost at this point, but than I entered the command 'shutdown -r now' and I lost everything! I wanted to start all over again (yes again) and tried to create a new virtual machine with a new virtual disk. But creating a new virtual disk would take me 16 hours and at a next try more than a whole day. Finally I created a dynamic virtual disk instead of a static disk of 300 Gb. See where this ends up.
