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

How to change UI Language on Ubuntu 11.10

After using the fancy login and Unity, I found one problem for different language user.
How do I change the UI to different language?
There is no Language option for me to choose.

Here comes the solution
In the System Settings

User Accounts

Language

And pick the Language you're going to use.
And login again.
Now you're using your language UI. Enjoy...

By the way, if you got better idea of how to change this in an easier way, please kindly let me know.
Thanks.

Ubuntu 11.10 Released

Upgraded my 11.04 to 11.10.
The new login screen is cool.

And the Unity feature now is supported even on my virtual machine.

Anyone who likes Ubuntu should try this then.

Find oracle program version

Sometimes you'll need to find out which version of your Oracle program is.
Maybe for patching purpose or bug issue.
Try this

strings | grep Header
adident Header

I personally like adident, much easier. =P
