Rapid fire Weblogic instances

Today we have made available the latest in our series of VM Templates for Oracle Solaris and our Oracle SPARC systems. This latest set of templates allows you to get an installed and configured Weblogic 12.1.3 instance up and running quickly and with minimal effort. You can download instances for OVM Server for SPARC and Oracle Solaris Zones here.

VM Templates bring a preconfigured, pre-installed, readly to go, deploy in minutes environment to use as is or as a base you can adapt for your production environments. This Weblogic template is simply the latest addition to the family, for example we have VM Template images for Oracle Solaris, you can see a full list here.

Oracle WebLogic Server 12c is for building and deploying enterprise Java EE applications with support for new features for lowering cost of operations, improving performance, enhancing scalability and supporting the Oracle Applications portfolio.

It's true - Docker coming to Oracle Solaris

Just a quick post, we announced a while ago that we will be bringing Docker to Oracle Solaris - you can read some background and find a link to the press release here.We'll hopefully be talking about developments at this year's Oracle Openworld so maybe I'll see you there.

Introducing Secure Live Migration

Secure Live Migration with Oracle Solaris Kernel Zones

Hopefully you have heard about the Oracle Solaris 11.3 Beta release but if not you can learn more here.

One of the key features of the Oracle Solaris 11.3 Beta release is the introduction of Secure Live Migration for Kernel Zones. This feature brings with it a couple of things of note.

First the obvious part - with live migration system administrators can limit the number and types of outages to applications and end users. This is particularly useful when there is a requirement to do system maintenance to the underlying OS or hardware. The Kernel Zones environments can be migrated off the source system before this maintenance. This is especially useful in today's datacenter where workloads (and owners of those workloads) running on systems can be many and varied. It is not always simple to organise a common outage window and can actually be quite frustrating.

Secondly the secure part. With secure live migration, not only is your data protected but man in the middle attacks are prevented. As with other security features in Oracle Solaris this is the default setting and automatically takes advantage of the available hardware crypto accelerators - meaning you get this protection at no additional performance cost. You may have to set up some security keys but our documentation walks you through this.

So, you are about to try live migrating a Kernel Zones, here are 10 things you might not know:

  1. We recommend that you use a 10GB link between the source and target systems
  2. Live migration with Kernel Zones is available on both SPARC and x86 systems
  3. On SPARC you will need to update your firmware to the appropriate system firmware level (see the docs for actual details)
  4. We recommend you perform live migration with a non-root user
  5. You will need running instances of these 3 services: live migration daemon, Remote Administration Daemon, and NTP server
  6. You can perform a dry run of a live migration with the -n option to zoneadm migrate
  7. Right now you cannot live migrate an LDom guest that has a running Kernel Zone inside it
  8. You might want to consider having a dedicated link for live migration or putting some bandwidth controls on
  9. Live migration tasks are performed by the zone itself so if you have CPU resource limits in place, make sure there is sufficient for the live migration task
  10. You don't have to have a config for a zone setup on the target system, you can configure a privileged to get this done automatically
That's it for now, good luck with the Oracle Solaris 11.3 beta and do let us know in the comments how you get on.

New features in Oracle Solaris Zones

 New Oracle Solaris Zones features

In case you missed it, and how could you, the Oracle Solaris 11.3 Beta was made available today. You can find the details here.

As always the Oracle Solaris Virtualization team has been very busy and there is a great list of things that they have delivered. Here are a few highlights:

  • Secure Live Migration: Kernel Zones can now be moved around the datacenter without causing an outage. End users can be unaffected and moved onto other systems whilst administrators perform key system maintenance. The secure part of the migration means that data is protected while man in the middle attacks are prevented.
  • Zones on Shared Storage (NFS): Now in addition to SAN and iSCSI you can put your zoneroot on NFS shared storage. Administrators can continue to benefit from snapshots, cloning and zone boot environments while choosing the appropriate storage for their environment (right now this is for Kernel Zones only)
  • Live Zone Reconfiguration: Originally introduced in Oracle Solaris 11.2, with the latest beta release the benefits of Live Zone Reconfiguration come to Kernel Zones with the ability to reconfigure the network and attached devices without the need for a reboot.
  • Virtualized Clocks for Oracle Solaris Zones: We've just had a leap second, with virtualized clocks support in Oracle Solaris Native Zones you can now test how a system will behave in advance. Of course you could always do this with Kernel Zones but now this functionality is extended across the entire zones family.
Here's hoping you enjoy running the new features in Oracle Solaris Zones - do let us know via the comments how you get on.

The best practice for Kernel Zones

Just a quick update today. The Oracle Solaris Zones engineering team have pulled together a best practice guide for Oracle Solaris Kernel Zones. Keep in mind that this is just general information for a generic setup, it's impossible to allow for every possible configuration or use case, but it's invaluable to help you get things going. Enjoy.

Kernel Zones in 5 minutes

I was lucky enough to get some time to tell Rick Ramsay about Kernel Zones, unfortunately it was only 5 minutes ;-) You can see the result here (go on you know you want to):

You can also get started with Oracle Solaris Kernel Zones with the help of this howto guide.

Which Oracle Solaris Virtualization

From time to time as the product manager for Oracle Solaris Virtualization I get asked by customers which virtualization technology they should choose. This is probably because of two main reasons.

  1. Choice: Oracle Solaris provides a choice of virtualization technologies so you can tailor your virtual infrastructure to best fit your application, not to have force (and hence compromise) your application to fit a single option 
  2. No way back: There is the perception, once you make your choice if you get it wrong there is no way back (or a very difficult way back), so it is really important to make the right choice

Understandably there is occasionally a lot of angst around this decision but, as always, with Oracle Solaris there is good news. First the choice isn't as complex as it first seems and below is a diagram that can help you get a feel for that choice. We now have many many customers that are discovering that the combination of Oracle Solaris Zones inside OVM Server for SPARC instances (Logical Domains) gives them the best of both worlds.

Second with Unified Archives in Oracle Solaris 11.2 you always have a way back. With a Unified Archive you can move from a Native Zone to a Kernel Zone to a Logical Domain to Bare Metal and any and all combinations in-between. You can test which is the best type of virtualization for your applications and infrastructure and if you don't like it change to another type in a few minutes.

Oracle Solaris Zones Preflight System Checker

Not using Oracle Solaris Zones? I have to ask, why not? With massive adoption on Oracle Solaris and the additions to Oracle Solaris Zones in Oracle Solaris 11 the reasons to place your applications inside a zone just become more and more compelling.

Now, there is one less reason not to move. It's there already as part of the product in Oracle Solaris 11, but for those of you with Oracle Solaris 10 systems you can now get access to the Oracle Solaris Zones Preflight System Checker on OTN (scroll down a bit from the link).

You can now evaluate an Oracle Solaris 10 host for migration into an Oracle Solaris Zone.  The following migration scenarios are supported:

  • Migration to an Oracle Solaris Zone on an Oracle Solaris 10 Host.
  • Migration to an Oracle Solaris Zone on an Oracle Solaris 11 Host.

And gives you the following capabilities:

  • Analysis of the Oracle Solaris configuration, including networking, storage, and Oracle Solaris Operating system features in use.
  • Analysis of application binaries.
  • Analysis of running applications.
  • Generation of a template Oracle Solaris Zone configuration to use on the target host.
