Reclaim VMDK space from thin disk on ESXi 5.0/5.1/5.5

There are 2 methods but both need you system to power down.

1. Use VMware convertor, it is free, but need to rename your VM and GUID also changed. It is not a very good choice if you have all those VM backup software that recognize GUID instead of VM Name  (However, I have tested both, it give the best result for reclaiming space, especially some space in LVM will not be able to be reclaimed by method 2 )

2. Do it Manually in 2 steps
- zero out all empty space (Windows sdelete, Linux secure-delete)
        Linux: execute "sfill -llfzv /" after installing secure-delete  (you might want to zero out swap also)
        Windows: "sdelete -z" (downloaded from microsoft technet)
- hole punching using vmkfstools in ESXi
         SSH into ESXi host and run this command: vmkfstools -K <vmdkname>

**if space not able to reclaim, try storage vmotion to thick then thin to force it happens.

Install Oracle 12c on SLES 11SP3

/etc/fstab
none                 /dev                 tmpfs      remount,size=6G       0 0


zypper install binutils gcc43 gcc-c++ glibc glibc-devel ksh libaio libaio-devel libcap1 libstdc++33 libstdc++43 libstdc++46 libgcc46 make sysstat

Install software only during when running ./runInstaller, do not create database

When it prompt for running root.sh script

Open terminal  (using oracle owner account)

1. su root    (don't use "su -" )
2. Execute those script required
3. Back to finish the installer
4. run ./netca to create LISTENER
5. run ./dbca to create your DB

For init script

you can install orarun packet using YaST or zypper

you have to modify /etc/sysconfig/oracle to select what service you want to start

/etc/init.d/oracle
1. Add 11g and 12c version support for startdb part
        ORACLE_VERSION=`$ORACLE_HOME/bin/sqlplus -v | awk '{split($3, V, "."); print V[1]}'`
        if [ $ORACLE_VERSION = "11" ]; then

to

        ORACLE_VERSION=`$ORACLE_HOME/bin/sqlplus -v | awk '{split($3, V, "."); print V[1]}'`

        if [ $ORACLE_VERSION = "11" ] || [ $ORACLE_VERSION = "12" ]; then

2.Change
  if [ ! -z "$ORACLE_HOME" -a ! -d "$ORACLE_HOME" ]; then
to
  if [ ! -z "$ORACLE_HOME" -a -d "$ORACLE_HOME" ]; then

3.
  # Set Intelligent Agent Start/Stop
  AGENT_VERSION="unknown"

to

 ORACLE_VERSION=`$ORACLE_HOME/bin/sqlplus -v | awk '{split($3, V, "."); print V[1]}'`

  # Set Intelligent Agent Start/Stop
  AGENT_VERSION="unknown"

After Cisco UCS Manager Upgrade to 2.1.X , FC and SAN disconnected due to Zoning behavior changed

How dare Cisco totally changed FC Zoning behavior in from 2.0 to 2.1 without warning, migration wizard or default allowing policy!!!!

It is totally not possible to upgrade to 2.1 without putting the whole SAN offline!

Once UCS Manager reboot according to follow manual, it block all FC traffic from Blade to SAN Storage.
And Cisco didn't add any warning here telling FC Zoning behavior will be changed. It still telling in the manual could upgrade without affecting service.

Please study complete about this sample config before upgrading to UCS Firmware bundle 2.1
