You do need to have
Oracle Certified Associate, Oracle Linux 5 and 6 System Administrator or
Oracle Linux Administrator Certified Associate (retired)
as well of course!
but if necessary you can pass 1z0-100 after 1z1-105 and you will still be awarded OL6 OCP!

Is there a pre-built VM with just Oracle Linux?

I want to try out installing Oracle Database 11gR2 on a Virtualbox without going through installing Oracle Linux in a Windows Host so I'm looking for a pre-built VM with just Oracle Linux. Most of the VMs available in Pre-Built Developer VMs (for Oracle VM VirtualBox) http://www.oracle.com/technetwork/community/developer-vm/index.html already have Oracle Database installed. It seems that my only choice is to use Enterprise Java Development VM. I notice there is something called Oracle VM template but it does not seem to be for Virtualbox. Thanks for any help.

I would second Bjorn's suggestion to just go ahead and install Oracle Linux from scratch. As a DBA you need to be familiar with a lot of OS level admin stuff, so installing the OS from scratch and doing the minimal configuration needed to install Oracle is, in itself, an important part of your professional development. If you take a shortcut of using a pre-built vm you are just stunting your own growth.

Is Oracle still actively creating AMIs for Oracle Linux?

Hi All,
I was wondering if any of you knows if Oracle is still actively creating new Oracle Linux AMIs for Amazon EC2? I can see the most recent one is Oracle Linux 6.1 while we are already at 6.3.
Now that Oracle has announced they are in the IaaS and PaaS business as well, do they stop supplying Amazon AMIs?
Bart.

I would never deploy the first point release of a major release into production. In my experience, Oracle rolls out 2 "releases" of each major version. The SECOND release tends to be production-ready for shops with serious HA requirements. Usually, this Second release also contains sneak previews of the important features of the next major Version--but these should be considered version 1.0 features and not relied upon. The FIRST release of a major version will contain those important features in a strong form suitable for the vast majority of shops--but it will still have lots of bugs. If you have to bounce your instance even once a month to work around a bug, you aren't getting close to HA.
My advice--the most stable version will always be the terminal release of the last version--currently 9.2.0.6. Similarly, the last point release of R1 will be quite stable. Realistically, 98% of the customer base can live with occasional downtime and bug problems, and will enjoy the new features of the latest software. Even for them, I'd wait for the second point release or higher for production. QA and DEV are different stories--jump on the latest wave and write code using the newest features. But wait for the second point release before going into production. Typically it will be out in a few months and will fix the glaring bugs.

ORACLE OCA and OCP Certification.

Hi Guys,
I am currently working in TCS BPO from last 2 years and 8 months for Cargo Revenue Accounting.
Done my Accounting and finance graduation.
I am very bored with the current profile I have and want to change the job. (though the place is good)
I am good in Excel and want to make a good career in IT. I want to go for ORACLE OCP and OCA certification.
Since I don't have a IT backround, will it possible to make a good career in IT???????????????? (looking at my profile)
Also, would like to know if it is really advisable to opt for ORACLE OCP and OCA. (looking at my profile)

Being good in Excel probably won't help much in the Oracle database domain IMO . How did you come to the decision that you want to do an OCP (DBA?) ? If that's taken because someone said that DBA job is a very cool job , well, than you should give a serious reconsideration because choosing something just because someone else is saying is good probably won't be something that you would be able to pull for a long duration. Anyways, the best bet would be to attend a SQL course and see if you do understand it and using it, how well you interact with the database. My suggestion would be to do the SQL course and then opt for the Financial application courses from Oracle which probably would suit better for your profile than opting for OCP/OCA. The choice , of course remains with you. Have a read of the Concepts guide at http://tahiti.oracle.com as well.

Oracle Linux versioning

Hi Avi, i'm quiet confuse if the release and distributions:
uname -a on my server show me 2.6.32-200.13.1.el5uek, that mean that it's a Entreprise Linux 5 ?
what the diff betwenn OEL5, OEL6 EL5UEK, EL6UEK, i'm lost.
Oracle Linux kernel appear as UEK ?
I just go to edelivery and found theses download :
1) Oracle Linux Release 6 Update 4 for x86_64 (64 Bit)     V37084-01     3.5G
2) Oracle Linux Release 6 Update 4 Boot iso image for x86_64 (64 bit)     V37088-01     197M
3) Oracle Linux Release 6 Update 4 UEK Boot ISO image for x86_64 (64 bit)     V37090-01     196M
4) Oracle Linux Release 6 Update 4 source DVD 1     V37086-01     3.1G
5) Oracle Linux Release 6 Update 4 source DVD 2     V37087-01     1.9G
If I build a server with the 1) what will be the result of a uname -a ?
What the purpose of the number 2 and 3 ?
So many questions ....

Oracle Linux 6 u3 Installation via FTP

There is a need to install OS (Oracle Linux 6.3) via FTP. The installation process started fine, but after I'd finished with partitions layout and hit "next" on the window displaying "boot loader operating system list", error appeared.
the error: "Unable to read package metadata from repository. This maybe due to missing repodata directory. Cannot retrieve repository metadata(repomd.xml) for repository".
Ftp shared folder is OS iso file itself.

What you are trying to accomplish is creating a local mirror of the software distribution. If you can't download from a mirror and you have the install DVD, copy the complete content and structure to a locally hosted HTTP or FTP directory.
As already mentioned, you need to specify the path to the root of the installation from where you can browse the "repodata" and "server" directory.
You can see what the installation is looking for by opening the repodata directory and analyzing "repomod.xml". This will show you the relative path and filename including the primary.sqlite.bz2 file.
Make sure all your files and directories in the installation root have world read and execute privileges (chmod -R 755 /install dir) and make sure your ftp server is setup accordingly providing the right FTP_HOME and permissions. Also, what is your FTP server, does it support Unix filenames or translate them?
You can probably try another machine use FTP to connect to the installation source and see if you can navigate inside the directories and get the files.

No GUI after reboot for Oracle Linux 6 installation

I am trying to resolve an Oracle Linux 6.2 (64 bit) installation issue. I selected Oracle Linux server default setup and after the reboot, the X-Window or KDE GUI graphical
interface does not come up. Instead, I get a command line prompt. Any idea how to resolve this issue to get an Oracle Linux 6 installation with graphical interface?

Spacewalk quickstart for Oracle linux 6.1

I have spacewalk installed following the instructions at https://fedorahosted.org/spacewalk/wiki/HowToInstall. I am completely stuck regarding what to do next.
My question is, how do I register my new spacewalk server with oracle linux network in order to subscribe to channels and start downloading updates?
I am under the impression there is a command similar to rhn_register to get this spacewalk server registered with OLN. I am at a dead end here any insight would be appreciated.

user12289873 wrote:
I have a basic question, is Oracle Management Pack for Linux a stand alone application or like the name indicates a pack to another larger application ?The Linux Management Pack is part of Oracle Enterprise Manager 11g Grid Control. It requires a full install of Grid Control, which includes Oracle Database 11g Enterprise Edition, Oracle WebLogic Server and Enterprise Manager Grid Control itself. However, once you have this installed, it is better suited to managing and maintaining large groups of Oracle Linux servers than Spacewalk. Spacewalk has no internal capabilities to manage Oracle Linux boxes and requires continual tweaking in order to keep it working, in the same way you can't actually manage large groups of Red Hat Enterprise Linux servers with it (requires the actual Satellite Server product) without lots of tweaking.
For example, in order for Spacewalk to work, you have to keep using the rep_populate.sh script you're currently using to create local yum mirrors to import into Spacewalk. The Spacewalk server itself won't talk to ULN without code hacking, as far as I could tell. While Spacewalk can be made to work, it's not straightforward and there is no documentation online on how to get it to work with Oracle Linux. It's a lot of trial and error with manipulating the CentOS instructions.
BTW, we include all the licenses you need for the entire stack with your Oracle Linux basic or premier subscription, so you can install the entire stack! Furthermore, you can then start to explore managing the rest of your Oracle products from a central location. Enterprise Manager 11g Grid Control can handle management from the operating system (or virtualization layer if you start looking at Oracle VM) all the way up the stack through the database to application servers and beyond.

Recent (July 2012) article about Oracle Linux on slashdot

Already a couple of days old, but I had some fun reading and adding in a couple of replies.
http://linux.slashdot.org/story/12/07/27/0236219/cowboyneal-reviews-oracle-linux

My best guess was that there are a couple of reasons for Oracle Linux:
1) I can imagine that technical aspects resulted in the UEK kernel. The RHEL kernel, at least in RHEL 5 was pretty old, perhaps blocking the development of Oracle's own kernel drivers.
2) Red Hat officially said "Yes, we undercut Oracle with hidden Linux patches", whining that they would steal Red Hat customers. I guess that was a very good reason for Oracle to branch its own kernel.
http://www.channelregister.co.uk/2011/03/04/red_hat_twarts_oracle_and_novell_with_change_to_source_code_packaging
Like I mentioned before, Oracle was the reason why I actually got hooked up to Linux again, actually in order to install Oracle 11g to study for OCP. RHEL was one of the more visible choices, but you cannot register with e.g. gmail, to be able to download RHEL for evaluation.
I checked the timeline of OEL and Solaris. The first version of OEL according to wikipedia dates to May 2007. The acquisition of Sun by Oracle was completed beginning of 2010. So I guess Solaris had bad luck since OEL was already doing the job for the Intel market. In some way I think it is a pitty, because Solaris has a nice user interface and special features, but development on Oracle Linux has continued, e.g. BtrFS, Dtrace.
I think it might take some more time before vendor certification for Oracle Linux (UEK) reaches the same level like RHEL, but I'm sure that will happen. Personally I don't give much about vendor certification, but some do. After all, people use applications, not the OS, so Oracle by "nature" rules over Red Hat, which is just an OS.

Oracle Linux Patching/Updates Impact on Oracle Database

I have several questions regarding Oracle Linux patching and its impact on Oracle Database.
3 node Cluster
Operating System: Oracle Linux Release 5 update 2
Kernel: 2.6.18-92.1.22.0.1.el5 x86_64 GNU/Linux
Grid Infrastructure: Oracle Grid Infrastructure 11g Release 2 (11.2.0.2)
Database: Oracle Database 11g Release 2 Enterprise Edition (11.2.0.2) with RAC option
ASM with ASMLib is being used for Data and FRA.
*1)* Given your at Oracle Linux Release 5 update 2, will applying only Security Patches require any changes to ASMLib, Oracle Grid Infrastructure and/or Oracle Database (software binaries, configuration etc.)?
*2)* Given your at Oracle Linux Release 5 update 2, will applying Bug Fixes and Security Patches to Oracle Linux 5 update 2 require any changes to ASMLib, Oracle Grid Infrastructure and/or Oracle Database (software binaries, configuration etc.)?
*3)* Given your updating from Oracle Linux Release 5 update 2 to Oracle Linux Release 5 update 8, will this require any changes to ASMLib, Oracle Grid Infrastructure and/or Oracle Database (software binaries, configuration etc.)?
I would most whole heartedly appreciate if someone could answer the specific questions asked, inline if possible. Our System Administrator is preparing to perform some patching and as the DBA I'd like to be certain what changes I need to prepare for? I also have a single instance database setup with Oracle Restart. I don't know if this impacts the answers above.
Thanks in advance.

How do you plan to apply Oracle Linux security patches? As far as I'm aware the yum security plug-in does not work with the Oracle public yum repository and there is no really feasible way to automate and determine security related patches only, unless you setup Oracle Enterprise Manager Grid Control (11g) or Cloud (12c) and have a subscription to Oracle ULN.
If you upgrade your Oracle Linux to the latest available version using the public yum repository, all patches, including errata will be applied. You cannot apply patches and stay on a specific release version unless you have a subscription and appropriate yum repository access.
As far as I'm aware there are no changes required to your Oracle database or ASM setup and configuration when updating the OS, provided the version of the Oracle database is supported for the specific OS version (ASM features like ADVM/ACFS are kernel version depending). Upgrading from one major release to another, such as upgrading Oracle Linux 5 to Oracle Linux 6 is not supported and will require upgrading the Oracle Database to 11.2.0.3. You can check the Oracle database certification matrix to determine which Oracle database release version is required for which OS version http://docs.oracle.com/cd/E11882_01/relnotes.112/e23558/toc.htm
The relinking of Oracle Database binaries is a common practice when updating the OS. I do not think it is necessary under Linux. Oracle binaries are typically standalone applications, or use Oracle provided libraries, or in some cases use OS shared libraries, which does not require relinking of Oracle binaries. Upgrading the Oracle database software of course requires relinking.

Oracle Linux and Java 7u10

Hi all,
I installed Oracle Linux Server 6.3 selecting "software Development System" (java 1.6.0 comes with it).
but I need to use Java 1.7
So I downloaded jdk-7u10-linux-x64.rpm
when I try to install it, I get the following error.
Unpacking JAR files...
     rt.jar...
Error: Could not open input file: /usr/java/jre1.7.0_10/lib/rt.pack
     jsse.jar...
Error: Could not open input file: /usr/java/jre1.7.0_10/lib/jsse.pack
     charsets.jar...
Error: Could not open input file: /usr/java/jre1.7.0_10/lib/charsets.pack
     localedata.jar...
Error: Could not open input file: /usr/java/jre1.7.0_10/lib/ext/localedata.pack
I can't uninstall java 1.6 because other rpm uses it.
Can someone tell me what the "proper" way to install Oracle Linux and Java 1.7 should be?
OR is there a Oracle Linux Server 6.4 coming out soon with Java 1.7 as its default package set ;-)
thanks in advance,
c.w.

You can ignore the errors. The files named in the error lines do not exist in the rpm package, but are there as .jar files
The following works under Oracle Linux 6.3 x86_64 (and probably other versions).
1. Open the following URL in a web browser on your PC:
<pre>
http://www.oracle.com/technetwork/java/javase/downloads/index.html
</pre>
2. Click the JDK download button, accept the license agreement and download the JDE rpm package.
3. Copy the following file to your Oracle Linux server (SFTP):
<pre>
jdk-7u10-linux-x64.rpm
</pre>
4. Login as root and use the YUM utility to install the RPM package.
<pre>
# yum install ./jdk-7u10-linux-x64.rpm
</pre>
5. Register the new installed java version, then change your default Java:
<pre>
# alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_10/bin/java 2
# alternatives --config java
</pre>
Display your default Java version:
<pre>
# java -version
java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)

How do you recompile the kernel for oracle linux 6.3

Hello,
I have installed Oracle linux 6.3 default settings on x86_64 bit pc
I have some questions:
1. What public yum repositories contain the oracle linux 6.3 kernel source code ?
2. Is the oracle linux 6.3 kernel source code on OracleLinux-R6-U3-src-dvd1.iso or OracleLinux-R6-U3-src-dvd2.iso , can I use this to recompile a new kernel ?
3. Do you have the steps/commands needed to set options and compile a installable kernel[rpm] on oracle linux 6.3 x86_64.
4. What gui tools are available in the desktop to manage settings e.g sound/volume or to install additional gui utilities.
5. Is there some documentation help on using the oracle linux desktop ?. If so where is it located .
Thankyou
Glenn

3. Do you have the steps/commands needed to set options and compile a installable kernel[rpm] on oracle linux 6.3 x86_64.No, you'd need to decide that for yourself. The kernel source is complex and can be very tricky to recompile.
4. What gui tools are available in the desktop to manage settings e.g sound/volume or to install additional gui utilities.Wow, topic shift. GNOME Control Center manages settings and installing new utilities is done by Pirut.
5. Is there some documentation help on using the oracle linux desktop ?. If so where is it located .Oracle Linux isn't intended to be used as a desktop. All the documentation is here:

Remote Desktop cannot verify the identity of the computer because there is a time or date diffrence between your computer and remote computer

Hello.....
I'm not able to log into Windows Server 2008 r2 server thorugh Remote Desktop connection, receiving below error message.
This issue is with only three servers in the environment
"Remote Desktop cannot verify the identity of the computer because there is a time or date diffrence between your computer and remote computer......"
The date/time is correct on the server when i checked in the console session of the server
Can see below messages in event logs
Event ID 1014:
"Name resolution for the name XYZdomain.com timed out after none of the configured DNS servers responded."
Event ID 1053:
The processing of Group Policy failed. Windows could not resolve the user name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).
Any thoughts ....

Hi,
Have you tried to connect these three servers with IP address instead of computer name or DNS name?
Check Remote Desktop Connection settings: Option-->Advanced-->Connect from anywhere-->Settings-->Connection Settings-->Select “Do not user an RD Gateway server”
