• Solaris 11

  - by user9154181

  Oracle has a strict policy about not discussing product features until they appear in shipping product. Now that Solaris 11 is publically available, it is time to catch up. I will be shortly posting articles on a variety of new developments in the Solaris linkers and related bits: 64-bit Archives After 40+ years of Unix, the archive file format has run out of room. The ar and link-editor (ld) commands have been enhanced to allow archives to grow past their previous 32-bit limits. Guidance The link-editor is now willing and able to tell you how to alter your link lines in order to build better objects. Stub Objects This is one of the bigger projects I've undertaken since joining the Solaris group. Stub objects are shared objects, built entirely from mapfiles, that supply the same linking interface as the real object, while containing no code or data. You can link to them, but cannot use them at runtime. It was pretty simple to add this ability to the link-editor, but the changes to the OSnet in order to apply them to building Solaris were massive. I discuss how we came to invent stub objects, how we apply them to build the OSnet in a more parallel and scalable manner, and about the follow on opportunities that have emerged from the new stub proto area we created to hold them. The elffile Utility A new standard Solaris utility, elffile is a variant of the file utility, focused exclusively on linker related files. elffile is of particular value for examining archives, as it allows you to find out what is inside them without having to first extract the archive members into temporary files. This release has been a long time coming. I joined the Solaris group in late 2005, and this will be my first FCS. From a user perspective, Solaris 11 is probably the biggest change to Solaris since Solaris 2.0. Solaris 11 polishes the ground breaking features from Solaris 10 (DTrace, FMA, ZFS, Zones), and uses them to add a powerful new packaging system, numerous other enhacements and features, along with a huge modernization effort. I'm excited to see it go out into the world. I hope you enjoy using it as much as we did creating it. Software is never done. On to the next one...

• How to Set Up a Hadoop Cluster Using Oracle Solaris (Hands-On Lab)

  - by Orgad Kimchi

  Oracle Technology Network (OTN) published the "How to Set Up a Hadoop Cluster Using Oracle Solaris" OOW 2013 Hands-On Lab. This hands-on lab presents exercises that demonstrate how to set up an Apache Hadoop cluster using Oracle Solaris 11 technologies such as Oracle Solaris Zones, ZFS, and network virtualization. Key topics include the Hadoop Distributed File System (HDFS) and the Hadoop MapReduce programming model. We will also cover the Hadoop installation process and the cluster building blocks: NameNode, a secondary NameNode, and DataNodes. In addition, you will see how you can combine the Oracle Solaris 11 technologies for better scalability and data security, and you will learn how to load data into the Hadoop cluster and run a MapReduce job. Summary of Lab Exercises This hands-on lab consists of 13 exercises covering various Oracle Solaris and Apache Hadoop technologies:     Install Hadoop.     Edit the Hadoop configuration files.     Configure the Network Time Protocol.     Create the virtual network interfaces (VNICs).     Create the NameNode and the secondary NameNode zones.     Set up the DataNode zones.     Configure the NameNode.     Set up SSH.     Format HDFS from the NameNode.     Start the Hadoop cluster.     Run a MapReduce job.     Secure data at rest using ZFS encryption.     Use Oracle Solaris DTrace for performance monitoring.  Read it now

• Tip #19 Module Private Visibility in OSGi

  - by ByronNevins

  I hate public and protected methods and classes.  It requires so much work to change them in a huge project like GlassFish.  Not to mention that you may well have to support those APIs forever.  They are highly overused in GlassFish.  In fact I'd bet that > 95% of classes are marked as public for no good reason.  It's just (bad) habit is my guess. private and default visibility (I call it package-private) is easier to maintain.  It is much much easier to change such classes and methods around.  If you have ANY public method or public class in GlassFish you'll need to grep through a tremendous amount of source code to find all callers.  But even that won't be theoretically reliable.  What if a caller is using reflection to access public methods?  You may never find such usages. If you have package private methods, it's easy.  Simply grep through all the code in that one package.  As long as that package compiles ok you're all set.  There can' be any compile errors anywhere else.  It's a waste of time to even look around or build the "outside" world.  So you may be thinking: "Aha!  I'll just make my module have one giant package with all the java files.  Then I can use the default visibility and maintenance will be much easier.  But there's a problem.  You are wasting a very nice feature of java -- organizing code into separate packages.  It also makes the code much more encapsulated.  Unfortunately to share code between the packages you have no choice but to declare public visibility. What happens in practice is that a module ends up having tons of public classes and methods that are used exclusively inside the module.  Which finally brings me to the point of this blog:  If Only There Was A Module-Private Visibility Available Well, surprise!  There is such a mechanism.  If your project is running under OSGi that is.  Like GlassFish does!  With this mechanism you can easily add another level of visibility by telling OSGi exactly which public you want to be exposed outside of the module.  You get the best of both worlds: Better encapsulation of your code so that maintenance is easier and productivity is increased. Usage of public visibility inside the module so that you can encapsulate intra-module better with packages. How I do this in GlassFish: Carefully plan out at least one package that will contain "true" publics.  This is the package that will be exported by OSGi.  I recommend just one package. Here is how to tell OSGi to use it in GlassFish -- edit osgi.bundle like so:-exportcontents:     org.glassfish.mymodule.truepublics;  version=${project.osgi.version} Now all publics declared in any other packages will be visible module-wide but not outside the module. There is one caveat: Accessing "module-private" items outside of the module is controlled at run-time, not compile-time.  The compiler has no clue that a public in a dependent module isn't really public.  it will happily compile it.  At runtime you will definitely see fireworks.  The good news is that you don't have to wait for the code path that tries to use the "module-private" items to fire.  OSGi will complain loudly when that module gets loaded.  OSGi will refuse to load it.  You will see an error like this: remote failure: Error while loading FOO: Exception while adding the new configuration : Error occurred during deployment: Exception while loading the app : org.osgi.framework.BundleException: Unresolved constraint in bundle com.oracle.glassfish.miscreant.code [115]: Unable to resolve 115.0: missing requirement [115.0] osgi.wiring.package; (osgi.wiring.package=org.glassfish.mymodule.unexported). Please see server.log for more details. That is if you accidentally change code in module B to use a public that is really a "module-private" in module A, then you will see the error immediately when you try to test whatever you were changing in module B.

• SPARC T5-4 Engineering Simulation Solution

  - by Mike Mulkey-Oracle

  A recent Oracle internal performance evaluation for computer-based product design demonstrated that Oracle's SPARC T5-4 server running MSC's SimManager simulation software with Oracle Database 12c consolidates the work of multiple x86 servers while delivering better overall performance.   Engineering simulation solutions have taken the center stage in helping companies design and develop innovative products while reducing physical prototyping costs, and exploring a larger design space, resulting in more design possibilities. For this solution, a single SPARC T5-4 server running Oracle Solaris 11 was deployed to consolidate the MSC SimManager server, the Oracle Database 12c server, and the web application server onto a single platform. An automotive design workload was deployed to demonstrate how the SPARC T5-4 server can be used to consolidate the work of multiple x86 servers and deliver better overall performance while reducing complexity and achieving optimal product designs.  A joint Oracle/MSC Software solution brief describes this in more detail:  A Simplified Solution for Product Lifecycle Management —MSC SimManager on a SPARC T5-4 Server

• Avoid overwriting of logs

  - by Koppar

  What usually happens is, the logs get filled up and begin getting overwritten, which makes them useless. To avoid it, use these 2 properties in the logging.properties file to suit your requirement: java.util.logging.FileHandler.count  = x (it is 1 by default, increase it to a bigger value) This number specifies the number of log files that can be created before overwriting starts. For instance, if you set it to 5, java0.log, java1.log ... java5.log will be created to log details so more information can be captured Likewise, java.util.logging.FileHandler.limit  would specify the size of each log.

• EOFs in Solaris 11

  - by nospam(at)example.com (Joerg Moellenkamp)

  Well ? from comments here and elsewhere, the two most worst things seemed to be the the removal of 32-bit support and removal of support for certain components. Just to set things into perspective: Solaris 10 was released 2005, the newsest class of machines not supported by it were the Ultra1. This one was released 1995. The UltraSPARC-Systems not able to run on Solaris 11 were released 2001. Well ? we have 2011 now ?. Regarding 32-bit support: Well ? I don't think "playing around with Solaris on old gear" is the problem. At first, most people are playing around with virtual machines. But there is something different: 64-bit computing was introduced for x86 in 2003 (yes ? it's really that old). I think this move is more hurting to the people using boards with the first-gen Intel Atom "Silverthorne" as small file servers. And then Solaris 10 won't disappear with Solaris 11

• Performance impact of the new mtmalloc memory allocator

  - by nospam(at)example.com (Joerg Moellenkamp)

  I wrote at a number of occasions (here or here), that it could be really beneficial to use a different memory allocator for highly-threaded workloads, as the standard allocator is well ... the standard, however not very effective as soon as many threads comes into play. I didn't wrote about this as it was in my phase of silence but there was some change in the allocator area, Solaris 10 got a revamped mtmalloc allocator in version Solaris 10 08/11 (as described in "libmtmalloc Improvements"). The new memory allocator was introduced to Solaris development by the PSARC case 2010/212. But what's the effect of this new allocator and how does it works? Rickey C. Weisner wrote a nice article with "How Memory Allocation Affects Performance in Multithreaded Programs" explaining the inner mechanism of various allocators but he also publishes test results comparing Hoard, mtmalloc, umem, new mtmalloc and the libc malloc. Really interesting read and a must for people running applications on servers with a high number of threads.

• Chessin's principles of RAS design

  - by user12608173

  In late 2001 I developed an internal talk on designing hardware for easier error injection, prevention, diagnosis, and correction. (This talk became the basis for my paper on injecting errors for fun and profit.) In that talk (but not in the paper), I articulated 10 principles of RAS design, which I list for you here: Protect everything Correct where you can Detect where you can't Where protection not feasible (e.g., ALUs), duplicate and compare Report everything; never throw away RAS information Allow non-destructive inspection (logging/scrubbing) Allow non-destructive alteration (injection) (that is, only change the bits you want changed, and leave everything else as is) Allow observation of all the bits as they are (logging) Allow alteration of any particular bit or combination of bits (injection) Document everything Of course, it isn't always feasible to follow these rules completely all the time, but I put them out there as a starting point.

• Solaris 11 VNC Server is "blurry" or "smeared"

  - by user12620111

  I've been annoyed by quality of the image that is displayed by my VNC viewer when I visit a Solaris 11 VNC server. How should I describe the image? Blurry? Grainy? Smeared? Low resolution? Compressed? Badly encoded? This is what I have gotten used to seeing on Solaris 11: This is not a problem for me when I view Solaris 10 VNC servers. I've finally taken the time to investigate, and the solution is simple. On the VNC client, don't allow "Tight" encoding. My VNC Viewer will negotiate to Tight encoding if it is available. When negotiating with the Solaris 10 VNC server, Tight is not a supported option, so the Solaris 10 server and my client will agree on ZRLE.  Now that I have disabled Tight encoding on my VNC client, the Solaris 11 VNC Servers looks much better: How should I describe the display when my VNC client is forced to negotiate to ZRLE encoding with the Solaris 11 VNC Server? Crisp? Clear? Higher resolution? Using a lossless compression algorithm? When I'm on a low bandwidth connection, I may re-enable Tight compression on my laptop. In the mean time, the ZRLE compression is sufficient for a coast-to-coast desktop, through the corporate firewall, encoded with VPN, through my ISP and onto my laptop. YMMV.

• Request-local storage in ASP.NET (accessible to the code from IHttpModule implementation)

  I need to have some object hanging around between two events I'm interested in: PreRequestHandlerExecute (where I create an instance of my object and want to save it) and PostRequestHandlerExecute (where I want to get to the object). After the second event the object is not needed for my purposes and should be discarded either by storage or my explicit action. So the ideal context where my object should be stored is per request (with guaranteed no sharing issues when different threads are serving requests... or processes/servers :) ) Take into account that actual implementation I can do is being made from a HttpModule and is supposed to be a pluggable solution for already written web apps (so the option to provide some state using static/instance variables in Global.asax doesn't look good - I will have to modify Global.asax on every web application). Cache seems to be too broad for this use. I tried to see whether httpContext.Application (of type HttpApplicationState) is good for me or not, but cannot get whether it is exactly per HttpApplication instance or not (AFAIK you can have several instances of HttpApplications used on different threads and therefore serving several requests simultaneously - then using storage shared between threads will not work correctly; otherwise I would use it because one HttpApplication instance serves exactly one request at a time). Something could be done with storing state on the HttpModule instances if I know for sure that it's exactly bound 1-to-1 with every HttpApplication instance running (but again I need a proof that HttpApplication instance is 1-to-1 with my HttpModule's instance). Any valuable and reputable links on these topics are much appreciated... Would be great to find something particularly well-suited for per request situation (because otherwise I may end up with something ulgy... probably either some 'broader' scoped storage and some hacks to have different keys in the storage for different requests, OR using a thread-local thing and in this way commit to the theory that IIS/ASP.NET will not ever serve first event from one thread and the second event from the other thread and so on)

• Convert Google Analytics cookies to Local/Session Storage

  - by David Murdoch

  Google Analytics sets 4 cookies that will be sent with all requests to that domain (and ofset its subdomains). From what I can tell no server actually uses them directly; they're only sent with __utm.gif as a query param. Now, obviously Google Analytics reads, writes and acts on their values and they will need to be available to the GA tracking script. So, what I am wondering is if it is possible to: rewrite the __utm* cookies to local storage after ga.js has written them delete them after ga.js has run rewrite the cookies FROM local storage back to cookie form right before ga.js reads them start over Or, monkey patch ga.js to use local storage before it begins the cookie read/write part. Obviously if we are going so far out of the way to remove the __utm* cookies we'll want to also use the Async variant of Analytics. I'm guessing the down vote was because I didn't ask a question. DOH! My questions are: Can it be done as described above? If so, why hasn't it been done? I have a default HTML/CSS/JS boilerplate template that passes YSlow, PageSpeed, and Chrome's Audit with near perfect scores. I'm really looking for a way to squeeze those remaining cookie bytes from Google Analytics in browsers that support local storage.

• iSCSI, failover and XenServer

  - by jemmille

  I have an iSCSI fail over implementation setup so if one of my storage units fails the other takes over immediately (it also runs the NFS shares). When fail over occurs, volumes are exported, the IP is switched to the other machine and the targets are reconfigured. The fail over of the storage system itself works just fine. I use NexentaStor for my filer. When I do a test (manual) fail over of my storage the following occurs: Note: I run the admin VM's on NFS and customer based VM's on iSCSI All NFS based VM's remain up and working perfectly through the failover and after All VM 's running on iSCSI eventually report the following: An error about not being able to write to a particular block An error about journaling not working Then the file system goes RO To get the VM's working again I have to do the following: Force shutdown of the "broken" VM's. Detach the iSCSI SR Re-attach the iSCSI SR Boot the VM on a different server (5 in my pool) If I don't boot on a different server I get this error "Internal error: Failure("The VDI <uuid&gt; is already attached in RW mode; it can't be attached in RO mode!")" The only way I have found to fix that error is to reboot the entire server it was running on previously which is obviously a huge pain. Currently multipathing is NOT enabled (but can be and the same thing still occurs). I have edited much of the /etc/iscsid.conf file to work with the timeout settings but to no avail. In short, my storage fails over properly but XenServer does not keep the connection alive. As a thought, the error that shows up in #4 above might be the ultimate cause and fixing that would fix everything? Any help would be appreciated more than you know.

• Home Server: cpu virtualisation, what to choose?

  - by Huygens

  I'm looking for virtualisation solutions for storage and OS for a home server. A sort of private cloud where I manage the storage space independently of the VM one. This question focus on VM (or compute instance) management and what would best suit my needs. (I have another question related to the storage management). My use cases are: A backup server: rsync and other services running. A personal cloud server: a kind of owned dropbox system, à la ownCloud. " users foreseen. A media server: streaming videos and displaying photos. Here my environement and wishes: Server: HP Proliant MicroServer with 8 GB RAM (AMD Turion dual core with AMD-V technology) OS types: only Linux (perhaps a *BSD VM in the future) Linux distributions do not matter, I'm familiar with RHEL, Fedora, Suse, Ubuntu, but any other recommandation will be fine 2-3 VMs foreseen: backup server, owncloud server and media server (optional). Those are only servers, so no graphical console needed (I don't need VirtualBox) By VM I mean a virtualised environment like KVM, Xen, etc. or a compute instance like with OpenStack storage should be "virtualised/cloudified" see my other question. VM should be able to be migrated to another server in the future if performance cannot be fullfilled anymore by the current server It does not matter if installation of such setup is complicated as long as management tools allow for easy maintenance I don't have Windows at home, so solution should be Linux friendly and would be nice to be web based. But native apps are OK too. System should be easy to enhance: by adding a new server to migate some of the VMs to it. So it's really a kind of private cloud on which I could run some Linux OS. I would prefer free (libre, as in a free speach) and open source tools. But it does not have to be free as in a free beer. So Xen, KVM, VitualBox or OpenStack? What would you recommend?

• How to resolve virtual disk degraded in Windows Server 2012

  - by harrydev

  I am using the new Storage Spaces feature in Windows Server 2012. I have the following disks: FriendlyName CanPool OperationalStatus HealthStatus Usage Size ------------ ------- ----------------- ------------ ----- ---- PhysicalDisk2 False OK Healthy Auto-Select 2.73 TB PhysicalDisk3 False OK Healthy Auto-Select 2.73 TB PhysicalDisk4 False OK Healthy Auto-Select 2.73 TB PhysicalDisk5 False OK Healthy Auto-Select 2.73 TB There is also a separate OS disk. The above disks are part of a single storage pool: FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly ------------ ----------------- ------------ ------------ ---------- Pool OK Healthy False False Within this storage pool some virtual disks are defined, see below: FriendlyName ResiliencySettingNa OperationalStatus HealthStatus IsManualAttach Size me ------------ ------------------- ----------------- ------------ -------------- ---- Docs Mirror OK Healthy False 500 GB Data Mirror Degraded Warning False 500 GB Work Mirror Degraded Warning False 2 TB Now the virtual disks are all running normal 2-way mirror, but two of the virtual disks are degraded. This is probably because one of the physical disks was offline for a short period of time. However, now the virtual disk cannot be repaired, even though, all physical disks are healthy. There is plenty of available space in the storage pool. This I cannot understand so I was hoping for some help, on how to resolve this? Below I have listed the full output from the Get-VirtualDisk CmdLet for the "Work" disk: ObjectId : {XXXXXXXX} PassThroughClass : PassThroughIds : PassThroughNamespace : PassThroughServer : UniqueId : XXXXXXXX Access : Read/Write AllocatedSize : 412316860416 DetachedReason : None FootprintOnPool : 824633720832 FriendlyName : Work HealthStatus : Warning Interleave : 262144 IsDeduplicationEnabled : False IsEnclosureAware : False IsManualAttach : False IsSnapshot : False LogicalSectorSize : 512 Name : NameFormat : NumberOfAvailableCopies : 0 NumberOfColumns : 2 NumberOfDataCopies : 2 OperationalStatus : Degraded OtherOperationalStatusDescription : OtherUsageDescription : Disk for data being worked on (not backed up) ParityLayout : PhysicalDiskRedundancy : 1 PhysicalSectorSize : 4096 ProvisioningType : Thin RequestNoSinglePointOfFailure : True ResiliencySettingName : Mirror Size : 2199023255552 UniqueIdFormat : Vendor Specific UniqueIdFormatDescription : Usage : Other PSComputerName :

• 150 TB and growing, but how to grow?

  - by seandavi

  My group currently has two largish storage servers, both NAS running debian linux. The first is an all-in-one 24-disk (SATA) server that is several years old. We have two hardware RAIDS set up on it with LVM over those. The second server is 64 disks divided over 4 enclosures, each a hardware RAID 6, connected via external SAS. We use XFS with LVM over that to create 100TB useable storage. All of this works pretty well, but we are outgrowing these systems. Having build two such servers and still growing, we want to build something that allows us more flexibility in terms of future growth, backup options, that behaves better under disk failure (checking the larger filesystem can take a day or more), and can stand up in a heavily concurrent environment (think small computer cluster). We do not have system administration support, so we administer all of this ourselves (we are a genomics lab). So, what we seek is a relatively low-cost, acceptable performance storage solution that will allow future growth and flexible configuration (think ZFS with different pools having different operating characteristics). We are probably outside the realm of a single NAS. We have been thinking about a combination of ZFS (on openindiana, for example) or btrfs per server with glusterfs running on top of that if we do it ourselves. What we are weighing that against is simply biting the bullet and investing in Isilon or 3Par storage solutions. Any suggestions or experiences are appreciated.
