Expand existing disk on VM Oracle Linux

VMWare Client Setting

Change the Hard Disk by double click

Utilities > Expand

Change the Maximum disk size to desired size, and Expand

Oracle Linux Setting

Turn on your Oracle Linux, type fdisk /dev/sda
p to see current partion status
n for new partition
give 3 to use next partition number, currently is 2
we use the whole increased space so accept the default cylinder parameter
and w to write the partition table to disk and exit

The result message want us to do a reboot, so do it.

After reboot still logon as root
pvcreate /dev/sda3
to create a physical volume

vgextend VolGroup00 /dev/sda3
to add the physical volume to volume group

vgdisplay
to see current Volume Group

We have 20G free to add volume group
lvextend -L+20G /dev/VolGroup00/LogVol00

resize2fs /dev/VolGroup00/LogVol00

Congratulation! You’ve sucessfully increase new space and can be used in your Oracle Linux on VMWare

Oracle Enterprise Manager Cloud Control Installation Precheck(Oracle Linux)

OS Library

For example, if you run the command on a 32-bit system, you should see something similar to the following:

glibc-devel-2.3.4-2.43(i386)
glibc-headers-2.3.4-2.43(i386)
glibc-2.3.4-2.43(i686)
compat-glibc-headers-2.3.2-95.30(i386)
glibc-profile-2.3.4-2.43(i386)
glibc-utils-2.3.4-2.43(i386)
glibc-kernheaders-2.4-9.1.103.EL(i386)
glibc-common-2.3.4-2.43(i386)
compat-glibc-2.3.2-95.30(i386)

For example, if you run the command on a 64-bit system, you should see something similar to the following:

glibc-common-2.3.4-2.43(x86_64)
glibc-devel-2.3.4-2.43(x86_64)
glibc-profile-2.3.4-2.43(x86_64)
glibc-headers-2.3.4-2.43(x86_64)
glibc-utils-2.3.4-2.43(x86_64)
glibc-2.3.4-2.43(x86_64)

And sysstat-5.0.5

Kernel Parameter Requirements

For installing an OMS or a Management Agent on Unix operating systems (32-bit or 64-bit), set the kernel.shmmax parameter to a value 1 byte less than 4 GB or 4294967295.
Oracle recommends this value to avoid lack of memory issues for other applications and to enable a complete and successful core file generation under any and all circumstances.
To verify the value assigned to kernel.shmmax parameter, run the following command:
cat /proc/sys/kernel/shmmax
To set the value for kernel.shmmax parameter, run the following command:
sysctl -w kernel.shmmax=<new value>

unzip Issue

But I could not install it via runInstaller at all.

After some research there is a solution for this

EM Cloud Control 12c RunInstaller Command Fails Before Launching Installer GUI With java.lang.NullPointerException In oraInstall_xxx.err File [ID 1369904.1]
The "unzip" binary provided by Oracle is in fact not able to correctly unzip the provided zip files for the Cloud Control installation.
Another release of the unzip should be downloaded from here: https://updates.oracle.com/unzips/unzips.html
The following version is needed:
# LINUX Intel (32bit and 64bit - Large file support)
Once this utility has been downloaded, proceed as described below :
oracle@vmtestoraem12c:/u01/app/software/em12c/ [rdbms1120] gzip -d unzip60_lnx.Z
oracle@vmtestoraem12c:/u01/app/software/em12c/ [rdbms1120] chmod u+x unzip60_lnx
oracle@vmtestoraem12c:/u01/app/software/em12c/ [rdbms1120] ./unzip60_lnx em12_linux64_disk1of2

Thanks to Yann Neuhaus, he recorded the detail of this.

Other notice

unzip the em12_linux64_disk1of2.zip & em12_linux64_disk2of2.zip into the same folder
