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

KERNEL=="sde1", OWNER="grid", GROUP="oinstall", MODE="0640"

 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

Format shared storage drives sdb and sdc using fdisk command. 

Repeat for storage drives sdd and sde.

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”

Start newly created Virtual Machine "jerry". Login as root and open Network Configuration window.

Deactivate and delete entries for eth0.bak and eth1.bak.

Edit “eth0”. On the “Ceneral” tab enter the “Address” and “Subnet mask” to match the entries in /etc/hosts. 

 On the “Hardware Device” tab click on “Probe” button, then click “OK”.

 Repeat for “eth1”.

 Repeat for “eth1” (continue).

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.

Run “oracleasm init” to load ASMLib kernel module and create/mount ASMlib filesystem.

Run "oracleasm createdisk" command to create 4 disks, CRS, DATA1, DATA2, and FRS1.

Restart "jerry" and repeat the first 2 steps Then run “oracleasm scandisks” to  

recognize the new volumes.
