Oracle VM 2.1.5 released.

A few days ago we released Oracle VM 2.1.5 which is available for download at http://edelivery.oracle.com/linux.

This release contains the following :

- bugfixes on both Oracle VM Manager and Oracle VM Server side
- the new webservices interface which I wrote a blog entry about, a few weeks ago
- external data-collector cronjob/thread moved into the Oracle VM Manager instance
- minor cosmetic improvements on the Oracle VM Manager side

This is a full CD release. So it is possible to do an install from scratch starting with 2.1.5, both the management and server side.

Prior releases 2.1.3 and 2.1.4 were only available updates through our online network (ULN).

The command line interface, which I mentioned that other entry, will be available shortly on ULN's Oracle VM channel, this cli will require Oracle VM 2.1.5+ and is just a python program/shell that will be able to run on a standard OEL environment.

For the last several months we have been working on a web services api (wsdl) and a command line interface (cli) for Oracle VM Manager. The cli uses the web services interface and is written in python so it can run on any platform where python is installed. The API exposes all the interfaces that the Oracle VM Manager UI components call, such as : manage server pools, servers, virtual machines, templates,...

It is now very easy to manage your Oracle VM server pools and virtual machines from a shell prompt. I was playing with this yesterday and figured I would take this opportunity to post an example.

In this example below, I had installed Oracle VM Manager (but not yet logged into it) and installed the cli scripts on one system and then I had installed Oracle VM server on another machine. On the Oracle VM server I had actually locally downloaded (manually) an Oracle VM template and created my own virtual machine without using the manager at all. So I actually create a new serverpool in Oracle VM Manager using the cli shell. I register my existing virtual machine and at the end show the list of commands we expose through the cli and through the webservices API. I think this is going to be very useful for many Oracle VM users.

It has been a while since I last wrote something about OCFS2. For those that don’t know what this is, OCFS2 is a feature-rich standard Linux cluster filesystem. Linus took OCFS2 into mainline in the 2.6.16 time frame and it is being actively maintained. The majority of the work has always been done at Oracle however folks from Novell have provided many contributions, as well as individuals like Christopher Hellwig.

OCFS2 is a really nice filesystem that is used by many people out there, if we track the ocfs2-users and ocfs2-devel mail lists it is clear that many people out there make use of it for their own applications.

We provide OCFS2 RPMs for Oracle Enterprise Linux(OEL) and Red Hat Enterprise Linux(RHEL) on oracle.com and we make the RPMs available integrated on ULN for the Oracle Unbreakable Linux support customers. Even though the code is in the 2.6.18 kernel that is used in RHEL5, they decided to not compile the modules so we compile them out of the kernel. (we do not modify the kernel config and build them in because that would be considered a change)

For people that want to use OCFS2 or play with it, it’s included in OEL as an extra (not modifications of existing RHEL code). You can get the RPMS for RHEL from the Oracle Technology Network (OTN). It is all free for use and download. If you need support you can purchase an Unbreakable Linux support subscription and that includes support for the filesystem.

You can find tons of information on our oss.oracle.com website http://oss.oracle.com/projects/ocfs2/. Some of the new features that are in the mainline Linux release of the filesystem are listed below. The most notable one is REFLINK which I will cover in more detail. All OCFS2 development is public and every change is immediately published on oss in our git repositories.

- extended attributes. in fact the value of each extended attribute can be as large as a regular file. Which is larger than even ext3 can do.

- Posix ACL support

- support for userspace cluster stacks. If needed it is possible to use OCFS2 with cman and pacemaker

- jbd2 support. This gives us 64-bit blocknumbers and we can theoretically support 4PB filesystems. with jbd1 the limit is/was 16TB per filesystem

- quota support

- metadata checksums and ecc. all metadatablocks in OCFS2 now have a checksum field. If the checksum fails, there is an ECC field that can recover a single bit error. If it is unrecoverable then OCFS2 will make this single inode unreadable but it does not or will not affect the rest of the filesystem. In most filesystems this would take the entire filesystem into read-only mode.

- improved inode allocation. This will help with filesystems which a huge huge number of files.

- indexed directories. This will improve performance of lookups of a single name.

- reflink which creates a target inode that shares the data extents of the source inode in a copy-on-write fashion.

Now, about reflink. The reason we implemented reflink is for Oracle VM. As you know, a virtual machine/guest owns one or more virtual disks. These virtual disks are represented as files on a filesystem hosted by the hypervisor. In the case of Oracle VM, if you have SAN or iSCSI storage, we put an OCFS2 filesystem on top of this, managed by the management domain (dom0). The virtual disks live on top of this OCFS2 volume.

These virtual disks can become very large, they usually are many GB’s in size. So when a user wants to create a clone of a virtual machine or create a virtual machine based on an existing template, we copy the content of the original virtual disks to a new set of virtual disks. By default this duplicates the amount of storage used.

ie. you have VM1 with a 40gb virtual disk (vm1/system.img) and you want to copy that to create VM2 based on the same virtual disk image (vm2/system.img).

The reflink feature in OCFS2 which was published to fs-devel and ocfs2-devel a while back, supports this operation through effectively creating hard links but with copy-on-write (or basically a point-in-time data hard link).

Today, we copy the file vm1/system.img to vm2/system.img. Tomorrow, we do reflink vm1/system.img vm2/system.img. At initial create time no additional space is used, no actual copying is done, it just creates a totally new inode/file and shares the data extents. As soon as a write is done to one or the other side, 1mb chunks are copied over where the writes occur.

This allows us to create instant copies of files (or in the case of Oracle VM, virtual disk images).

Some of the advantages of reflink are :

- Each “hard link” or point-in-time copy, is a regular file for the OS, for an application etc, so there are no changes needed to applications or backup software. This is totally transparent, there is no container around these files etc. Unlike vmdk and vhd where the snapshots live inside the containers.

- It is fully cluster safe so this works in an OCFS2 filesystem cluster so the link and the COW works on any node even if the file is used and opened on another node. This allows us in the Oracle VM case to create snapshots and run these new VMs on a different node than the original VM is running.

- This is a generic feature just like symlink. It is available to any user or application.

- It is open source (part of OCFS2 code) free to use for anyone.

Below is an example of reflink. It shows the diskspace usage, it shows the time it takes to complete the commands and also a simple modification done with dd to one file and show how that affects both files.

Enterprise-Quality Support, More Value

Oracle Unbreakable Linux launched two years ago as a support program for existing Red Hat Enterprise Linux (RHEL) implementations or for new Oracle Enterprise Linux implementations. Oracle Unbreakable Linux program is about enterprise-class support that customers can't get (or is not available) from Red Hat. It has never been about creating a knock-off or forked Linux distribution. There is no migration, or switch, needed for existing RHEL users to move to Oracle Unbreakable Linux support.

With more than 30+ years of experience supporting the largest business- critical data centers around the world, Oracle brings the highest support quality, more value, and proven business practices to Linux support, including the following items Red Hat can't:
· 7500+ professionals providing 24x7, global support in over 145 countries
· Lifetime support policy
. 7+ years of general product support with the ability to extend to unlimited number of years
· Premier backporting
. Request backport of specific features eliminating pressure to upgrade with every update release

Customers Are Benefiting

Oracle is the trusted advisor to many CIOs looking for more value for their entire application stack; including support for Linux.

· 79% of databases that run on Linux, run Oracle
· Over 30% of Oracle Applications are deployed on the Linux platform
· Over 50% of recent Oracle Fusion Middleware deployments are on the Linux platform

Oracle's Linux business includes thousands of customers using Oracle on Linux and Oracle Unbreakable Linux support for their Linux deployments.

Due to dissatisfaction with Red Hat's quality of support as well as a desire to get more value, many users have switched from Red Hat Support to Oracle Unbreakable Linux Support.

Read why Interactive One switched from Red Hat to Oracle Unbreakable Linux Support.

Oracle's Linux Commitment

Oracle offers a complete and comprehensive software stack and single point of support for Linux and also offers the risk mitigation and value that users demand, especially in today's tough economic times. Oracle has a solid Linux business and a long-term commitment to continue to enhance Linux as a choice for business-critical deployments.

Earlier today I was doing my usual daily tech industry news review and ran into a story that talked about how VMware announced a new product to configure their management software stack for high availability, which according to the article is called vCenter Server Heartbeat.

You can find the article here:
http://searchservervirtualization.techtarget.com/news/article/0,289142,sid94_gci1347468,00.html

Previously one had to take a set of servers, install Microsoft Windows, install Microsoft Cluster Services (so you need at least an Enterprise edition Windows server version), then install the VMware management components and a database on top. Then you had to set up all those components from the various vendors to get it to offer server, application or OS failure protection. Then configure MSCS and register the various components. With this new announcement, it seems that it will now be possible to do this without the need for Microsoft Cluster Services.

All this comes, again according to the article, at an extra cost: "Pricing was listed at $9,995 per existing vCenter instance – including the database -- or $12,995 when bundled with a vCenter license." So one has to purchase a license for VMware vCenter, Microsoft Windows Server, vCenter Server Heartbeat, times 2, and support for these products. I believe this will really add up.

Now let's looks at Oracle VM.
Oracle VM, has Oracle VM Manager which is our own management server to manage pools of Oracle VM Servers with their virtual machines. Oracle VM Manager runs on Linux (Enterprise Linux) and uses an Oracle database (by default we even use/can use the free version Oracle XE) for its backend database server and OC4J for the J2EE application container.

Oracle VM Manager can easily be set up in an HA environment where it is possible to protect it against hardware failures or (unlikely) crashes of the application, including the database or the operating system, through the use of Oracle Clusterware. The white paper at the link below describes how to use Oracle Clusterware to protect Oracle VM Manager in a 2 server setup on Enterprise Linux:
http://www.oracle.com/technologies/virtualization/docs/ovm-clusterware-whitepaper.pdf

Basically Oracle offers all the software components required to set up – an HA Management server environment, with no need for third party products and multiple vendor licenses. Additionally, if you have a Linux OS support subscription from Oracle (which starts at $499 for a one year Basic Limited support subscription, per server), the Oracle Clusterware usage is included at no extra cost. This means that for two servers, Oracle VM Manager, Oracle Enterprise Linux and Oracle Clusterware, the whole thing comes at just about $1,000 with 24/7 support for a year. For detailed pricing, visit: http://store.oracle.com/linux. And on top of that Oracle Clusterware has been around for many years and is the software used by Oracle Real Application Clusters.

Everything is provided and supported by Oracle. That's a pretty good deal. And we're not yet talking about the server side (Oracle VM server or VMWare ESX server).

I would like to remind everyone that you are allowed to download and use Oracle Enterprise Linux or Oracle VM for free. It is not required to purchase a support subscription first. Also, you can in fact run this in production, without a support subscription. You can redistribute this to others inside your own company or to anyone else outside, without a special contract, without a redistribution agreement, without a support subscription.

And best of all, this is not an alpha version of some future possible release with no supported products on top, this is the exact same code you can use on test, development, pay, no pay, supported, non supported production systems.

Why does this matter ?

Well, certain Linux Distribution / Support vendors don't let you freely download their product unless it's pre-alpha stage, have been known to claim that customers can't freely use this product without paying support (despite the GPL), and have even insisted through their sales team that a customer must power off servers when the server's support subscription expired. Now that doesn't make much sense and I wonder how this all works with a product that is released under the GPL. But this sort of FUD is not good. Especially not when it comes from a self proclaimed open source leader.

*OracleVM 2.1.2 released !*

I am very excited to announce the new 2.1.2 release of Oracle VM. This is now available from the usual location : http://edelivery.oracle.com/oraclevm

A bunch of new features are included in this release :

* Guest VM HA : auto-restart a failed VM or, if a server fails, auto-restart all failed VMs that were running on that server (and that had the HA option enabled). A quick and easy way to increase application up-time without having to change anything inside your guest VM. Earlier this week(Monday), this was demoed during a keynote at Oracle World by Chuck Rozwat.

* P2V : the server CD allows you to boot in p2v mode which copies over the disk images from a physical server to an Oracle VM server in a server pool and creates a virtual machine for you.

* VMWare V2V: we now automatically convert VMware images into Oracle VM format instead of the manual steps that were previously required.

* Secure Live Migration:  Notice I said "secure".  That's because we are now the first major virtualization solution to SSL encrypt migration traffic natively and by default so you are not exposing sensitive information like account numbers and passwords in the clear.

* Other features such as rate limiting of virtual network interfaces, Disk IO priorities for guest virtual disks etc.

* And, RAC has now been certified with Oracle VM, adding to the list of Oracle products we've cerftified with.

And just like with the previous release, its free to download (both Manager and Server), free to use, no license keys, no alpha/be-our-tester version, all features included, no cpu limitations. Just pay for support, if you need it. You don't get that from anyone else.

Last year at Oracle World, Oracle launched a new exciting product called Oracle VM. It is our own x86/x86-64 virtualization product solution which adds a real hypervisor underneath our full product stack. For those that forgot - go to http://www.oracle.com/virtualization for more information.

This gives us a very nice top to bottom product layer :
application (our various applications offerings) -> middle tier (our various middleware suite offerings) -> database tier (our various database products) -> OS (Oracle Enterprise Linux) -> Virtualization (Oracle VM).

All fully certified and supported by Oracle, top to bottom.

All fully managed by Oracle Enterprise Manager and Oracle VM Manager.

So what would be the logical next step ? Well - make pre-installed and pre-configured virtual machines of these components and deployment becomes a "download -> start virtual machine" process.

In the virtualization world most people talk about virtual appliances however we decided to call it virtual machine templates. The reason for this is that we are looking at more complex and more feature rich product components. In many cases people want to make changes to the installations. We have to be able to do upgrades and apply security patchsets and so on. So we decided not to create blackboxes but create virtual machine images which have been pre-configured with recommended patches, recommended OS settings, then the Oracle product on top with the recommended patchset level and also other changes and fixes applied.

The first few templates are now already available for download. There are 2 siebel software templates, one for the middle tier and one for the database and there are the recently released Oracle Enterprise Manager templates, also one middle tier and one database tier.

The downloads might be pretty hefty but once downloaded you can just import these into Oracle VM and start a virtual machine. All you have to do is provide a password or 2 and an ip address and hostname. You then end up with a fully configured Siebel product stack or Enterprise Manager product stack .In the EM one, we even added a virtual disk which contains full yum repositories for Oracle Enterprise Linux so you can do patch management and provisioning out of the box for the OS as well.

The license on these templates contains free download and free trial use with the option to purchase a product license and use in a production environment (for the traditional Oracle products). Oracle VM and Oracle Enterprise Linux are free download and free use.

We will continue to add more templates on a regular basis and enhance existing ones but this is a very exciting project which will help our partners and our customers get started on using Oracle products out of the box. Hope you like it. And.. more to come

Yesterday morning I was at the Intel Developer Forum (IDF) in San Francisco. Intel announced this new community effort called lesswatts. (http://lesswatts.org) (I suggested fewerwatts but the folks involved said less sounded better...ok then

Either way - the idea behind the project is to help Linux make better use of the new power features that are in the various new chips and also provide users with the tools and information needed to set up the OS and applications in order to make more efficient use of resources. This will then result into power savings. Lower power bills, better for the planet and so forth.

Renee James, general manager of Intel's software group made the announcement in her keynote and I joined her on stage for a few minutes to explain how Oracle and Intel are working together to get this into the hands of our customers. This project is important to Oracle as a consumer of Linux and because of the Unbreakable Linux support program we provide to our customers.

This really means a few things

Oracle plans to:

- Extend the validated configurations program we have (http://www.oracle.com/features/hp/linux-validated-0606.html) and add hints and tips to set up a system with power savings in mind. This will be based on internal (Oracle) testing.

- Help with making Linux be able to use the hardware features better (kernel and userspace code changes). At the same time, Intel will spend a lot of effort on power management in Linux.

One complaint we sometimes hear, is that even though Linux has a lot of new functionality and rapidly picks up new technologies, the distributions lag. Mainline Linux testing is still not on par and backporting untested features can be difficult. We have a lot of work to do here but there also is a lot of opportunity to work together and make this happen.

Bottom line :using less/fewer watts is good for all.

Yesterday, a few folks sent me this link : http://www.linux-mag.com/id/4120/. I read it with interest as there are a few things, ignoring the tone of the article, which I thought were interesting. 

I don't know how to make this clearer, so I'll reiterate what we've said from the start...Oracle Enterprise Linux is fully source and binary compatible with RHEL, so the same "experience" exists when you install either product. For good or bad. If we made it different, so that Oracle's installation was different, there would have been a complaint that we are not compatible. hmm no win ? But remember, our focus is on enterprise-quality support and that means we strive to provide customers with the best possible user experience. Oracle Enterprise Linux is compatible with RHEL and what we do is provide a great support service on top of either/both. We didn't launch a Linux distribution business, we started a Linux support program. I think we have made that very clear many a times. 

Next is the claim that it takes many hours to get things working... that made me wonder... So I decided to take an old laptop, a 2gz p4 with 1gb ram, install everything from scratch(OS + Oracle database 10gR2) and time it. To the minute (or second) give or take a few seconds, but given the comment of "many hours" those few seconds surely won't matter. 

So I started at 1:50pm, booted up my laptop and with the EL4U5 for x86 DVD. At 2:01pm, I had the entire distribution installed and the system did the reboot. This was the default installation, no customizations.  

The box reboots. I configure a regular user, oracle. It starts up Xwindows, I run rhn_register as the root user and configure my box to connect to ULN. This took me 3 whole minutes ! Time flies... 

then I run :

so now we are at 2:05pm.  

I grab the oracle 10.2.0.1 CD and put it into the laptop and start runInstaller.

This is a standard out of the box install with the starter database created. 

2:15pm. software installed, products relinked and creation of the clone/seed database started. Remember, this is a laptop with one of those 5400rpm disks.  

2:26pm. database created, configuration assistants ran, I type as fast as I can to run the root.sh scripts and about a minute later. done. 

2:27pm, after 37 minutes, on the slowest machine I could find near me, I installed the OS from scratch (EL4U4), I installed Oracle RDBMS 10.2.0.1 with the default started database from scratch. And now have everything up and running and configured. Including a registered system with ULN.  

So for the default Linux install, get the oracle-validated rpm which we have talked about plenty and clearly tell people this is the sort of add-on stuff we can provide to make it easy to install Oracle products without having to modify the distribution. 

Maybe I cheated a few seconds left or right while reading the clock, so say 38 minutes. Still far less than an hour, and certainly not many many hours and certainly no installation problems, at all. No errors, no finding packages from CDs to get something going. Just hit the next button and enter a password here or there. 

Did I miss something ? It didn't feel like rocket science to me, even though, admittedly, it wasn't my very first Linux or Oracle installation. Someone want to try and beat me on installation time ? I can try it on a current desktop, I bet I can bring it down to about 20 minutes. Yes, it really is that easy and on top of that, if I had a problem, I could call support and I am sure they'd have been very helpful :)
