Create /u01/staging directory, transfer oracleasmlib-2.0.4-1.el5.i386.rpm file there using FTP (or any other method), and install the package.
[root@localhost ~]# mkdir /u01/staging
[root@localhost ~]# chown grid:oinstall /u01/staging <FTP TRANSFER>
[root@localhost ~]# cd /u01/staging
[root@localhost staging]# ls ora*

[root@localhost staging]# rpm -Uvh oracleasmlib-2.0.4-1.el5.i386.rpm
Why install VMware tools?
• Improved video performance
• Mouse synchronization with host OS
• Improved mouse performance
• Copy and paste between host OS and guest OS
• Not required to be installed
Create users and groups.

Activate the change at runtime by execuing: /sbin/start_udev
Increase user limits for users grid and oracle.
/etc/profile (and/or /etc/bashrc)
if [ \$USER = "oracle" ] || [ \$USER = "grid" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384

"Hack" nslookup to avoid installation errors.
1. Rename the original nslookup file to nslookup.orig:
mv /usr/bin/nslookup /usr/bin/nslookup.orig
2. Create the new nslookup file with the contents below:
#!/bin/bash
# Replace 10.66.0.114 with your primary DNS
# Replace 10.66.0.230 with your SCAN IP address
HOSTNAME=${1}
if [[ $HOSTNAME = "acme" ]]; then
echo "Server: 10.66.0.114"
echo "Address: 10.66.0.114#53"
echo "Non-authoritative answer:"
echo "Name: acme"
echo "Address: 10.66.0.230"
else
/usr/bin/nslookup.orig $HOSTNAME
fi
3. Change the privileges on the newly created file: chmod 755 /usr/bin/nslookup
Deactivate the NTP service.
/sbin/service ntpd stop
chkconfig ntpd off
mv /etc/ntp.conf /etc/ntp.conf.original
rm /var/run/ntpd.pid
chkconfig --list ntpd
Create new virtual machine jerry as a copy of virtual machine tom.
• Shutdown virtual machine tom.
• Create Windows directory C:\Virtual Machines\jerry
• Copy all contents of C:\Virtual Machines\tom to C:\Virtual Machines\jerry
• Rename all files with names that contain string “tom” to replace it with “jerry”.
• Edit file C:\Virtual Machines\jerry\jerry.vmx and replace all occurrences of string “tom” with string “jerry”.
• Go to the VMware Server Home Page.
• Click on “Add Virtual Machine to Inventory” in the “Commands” section.
• Select "standard" -> "jerry" -> "jerry.vmx" and click "OK".
• Select “I _copied it” on the warning pane and click “OK”
Edit “eth0”. On the “Ceneral” tab enter the “Address” and “Subnet mask” to match the entries in /etc/hosts.
On the DNS tab, specify “Hostname”, “DNS search path”, “Primary DNS”, “Secondary DNS”, and "DNS search path"
fields. The last 3 are optional.
Save network configuration and exit Network Configuration window. Restart the network.
1. <Ctl-S>; <Ctl-Q>
2. service network restart
Start tom, login as root, and run "oracleasm configure -i" command to configure the Oracle ASM library driver.
Restart "jerry" and repeat the first 2 steps Then run “oracleasm scandisks” to
recognize the new volumes.
Modify .bashrc for user grid on "tom".
