• OBIEE 11.1.1 - Introduction to OBIEE 11g Full Sample App

  - by user809526

  Isn't it nice to discover OBIEE 11g around a nice "How To" catalog of features? to observe OBI and Essbase relationships at work? to discover TimesTen? The OBIEE 11g Full Sample App (FSA) is a comprehensive collection of examples designed to demonstrate the latest Oracle BIEE 11g capabilities and design best practices: Enhanced visualizations as Geo-spacial maps and interactive dashboards, Action Framework,  BI Publisher, Scorecard and Strategy Management, Mobile style sheets, Semantic layer modeling, Multi-source federation, Integration with products such as Essbase, Oracle OLAP, ODM, TimesTen, ODI and more The FSA is intended to be comprehensive, it is big (see CAVEAT below). The FSA is not an Oracle product, it is a good will free deployment of OBIEE/Essbase designed to exemplify OBIEE features, infrastructure and security around the Fusion Middleware components. Its contents and code are distributed free for demonstrative purposes only. It is neither maintained nor supported by Oracle as a licensed product. The OBIEE Full Sample App is independent of the default Sample App that comes with the OBIEE product. BENEFITS The FSA helps as a demonstrator of OBIEE 11g best practices, a tutorial, an environment "Test & Scrap", a SR bench (regression, conflicts), a tuning bench, a quick ready made POC seed for projects, a security options environment, ... The FSA - Is organized around a catalog of functional features - Has been deployed over 1000 times, it should be stable RELEASE The Full Sample App (V107) is bound to OBIEE 11.1.1.5 and Essbase 11.1.2.1 (November 2011). The FSA release dates are independent of the Product GA date (OBIEE). In early December 2011, a new functional Patch (V110) is released. It is easily applied (in less than 15 mins) on top of OBIEE SampleApp 11.1.1.5 (V107). The patch (V110) includes additional functional examples:        1. Web Catalog Statistics Application: Provides detailed insight into your web catalog content, dormant catalog objects, webcat impact analysis for metadata changes and more        2. Data inflation Scripts: A set of simple SQL procedures to quickly inflate SampleApp Fact and Dimension data to millions of records in a few minutes        3. Public Content Extensions Framework: A patching framework for public examples and contributions leveraging SampleApp        4. Additional report examples (including bridge report, external chart integrations) and bug fixes DISTRIBUTION as VBox image (November 2011) The ready made VBox image is designed to run on Virtual Box. It can be converted to VMware (see another BLOG). 1/ http://www.oracle.com/technetwork/middleware/bi-foundation/obiee-samples-167534.html VBox Image Deployment Guide Sampleapp_v107_GA.ovf - VBox image key file The above http URL provides the user:password for the ftp URLs below. 2/ ftp://user:[email protected]/static/SampleAppV107/ 12 "7-zip" files Sampleapp_v107_GA_7_20.7z.001 -> .012 We recommend 7-zip file manager for unzipping (http://www.7-zip.org/). Select Unzip here option, it will create the contents under a directory named "SampleApp_10722". On Windows, it is important to download and save zip file under the root directory (e.g. C:\ or D:\) because of possible long pathnames. 3/ ftp://user:[email protected]/static/SampleAppV107/Unzipped_Version/ 4 files Sampleapp_v107_GA-disk[1234].vmdk Important note: Check the provided checksums (md5sum).

It is strongly advised you run some memory check program eg MEMTEST in GRUB boot manager. Running md5sum repeatedly onto the very same big file must be consistent [same result], else a hardware memory problem is suspected. For Virtual Box, you should most likely enable VT-X (Vanderpool) hardware virtualization in BIOS. A free disk space of 80 GB is required to perform safely the VBox image installation. A Virtual Machine of minimum 6 to 7 GB memory fits the needs of combining OBIEE and Essbase execution.

• Converting an Oracle VM VirtualBox VM into an Oracle VM Server image

  - by wim.coekaerts

  As we are working on tighter seemless moving of VM's between the 2 products, here are a few simple steps to convert an existing Oracle VM VirtualBox image over. Steps involved to make it easy/straightforward : (1) When creating a VM in Virtualbox, using Oracle Linux as an example, make sure that /etc/fstab only uses labels. Do not use hardcoded device names. instead of an entry /dev/sda1 /u01 ext3 defaults 1 1 use LABEL=foo /u01 ext3 defaults 1 1 for more info on labels : man e2label or use a logical volume /dev/VolGroup00/LVfoo /u01 ext3 defaults 1 1 Doing so will make it easier to have an OS boot up on a different hypervisor with potentially different device names. For instance, the VirtualBox VM might expose a scsi driver while in Oracle VM Server you might end up with an ide disk, this then changes /dev/sda to /dev/hda. (2) If you have a VM created that you want to convert, then shut down the VM in VirtualBox and convert the image files : go the the directory that contains your HardDisk image files (.VirtualBox/HardDisks/* as an example) for each of the virtual disks run the following command : VBoxManage clonehd virtualdiskfilename.vdi system.img --format raw where virtualdiskfilename.vdi is the original VBox VM file (this can also be a vmdk file) and system.img is the name of the virtualdisk for Oracle VM. this can be any filename as well, I typically use system.img to specify the boot disk (as is common for Oracle VM template creation) (3) create a vm.cfg To run a VM converted from VirtualBox, you have to create a vm.cfg for Oracle VM server that creates an HVM guest. The easiest is to use a simple hvm vm.cfg and change it for your vm. I have an example here : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' disk = ['file:system.img,hda,w', 'file:oracle.img,hdb,w',',hdc:cdrom,r',] kernel = '/usr/lib/xen/boot/hvmloader' memory = '1024' name = 'vmname' on_crash = 'restart' on_reboot = 'restart' pae = 1 serial = 'pty' timer_mode = '0' usbdevice = 'tablet' vcpus = 1 vif = ['bridge=xenbr0,type=ioemu'] vif_other_config = [] vnc = 1 vncconsole = 1 vnclisten = '0.0.0.0' vncpasswd = '' vncunused = 1 If you take the above vm.cfg, all you need to do - modify disk = (add your virtual disks in there) - modify memory = (amount of memory your VM needs) - modify name = (enter a name for your VM here) - modify vif = (might want to replace bridge=xenbr0 to the bridge you want to use) if you want more than 1 vcpu or other changes of course you have to make those as well. (4) copy this set of files onto your Oracle VM server or onto a webserver in a subdirectory and import the template through Oracle VM Manager. You can also just start the vm using xm create vm.cfg if you like. And that's it. As I said, we are working on automation around all this but it is relatively trivial to convert VM's over as long as you take the basic issues into account. Primarily the set up of the filesystems and the use of labels in /etc/fstab. There are other potential things to look at, such as network config. If you want to make that part clean then prior to shutting down the VM change /etc/modprobe.conf and/or add the mac address of the VM into the vm.cfg in the vifs line. The good thing, at least with Linux, is that even tho the virtual hardware changes, Linux will deal with it just fine (e1000 vs 8139 realtek, ide vs scsi etc). hope this helps.

• How can I back up my ubuntu system?

  - by Eloff

  I'm sure there's a lot of questions on here similar to this, and I've been reading them, but I still feel this warrants a new question. I want nightly, incremental backups (full disk images would waste a lot of space - unless compressed somehow.) Preferably rotating or deleting old backups when running out of space or after a fixed number of backups. I want to be able to quickly and painlessly restore my system from these backups. This is my first time running ubuntu as my main development machine and I know from my experience with it as a server and in virtual machines that I regularly manage to make it unbootable or damage it to the point of being unable to rescue it. So how would you recommend I do this? There are so many options out there I really don't know where to start. There seems to be a vocal school of thought that it's sufficient to backup your home directory and the list of installed packages from the package manager. I've already installed lots of things from source, or outside of the package manager (development tools, ides, compilers, graphics drivers, etc.) So at the very least, if I do not back up the operating system itself I need to grab all config files, all program binaries, all created but required files, etc. I'd rather backup too much than too little - an ubuntu install is tiny anyway. Also this drastically reduces the restore time, which would cost me more in my time than the extra storage space. I tried using Deja Dup to backup the root partition, excluding some things like /mnt /media /dev /proc etc. Although many websites assured me you can backup a running linux system this way - that seems to be false as it complained that it could not backup the following files: /boot/System.map-3.0.0-17-generic /boot/System.map-3.2.0-22-generic /boot/vmcoreinfo-3.0.0-17-generic /boot/vmlinuz-3.0.0-17-generic /boot/vmlinuz-3.2.0-22-generic /etc/.pwd.lock /etc/NetworkManager/system-connections/LAN Connection /etc/apparmor.d/cache/lightdm-guest-session /etc/apparmor.d/cache/sbin.dhclient /etc/apparmor.d/cache/usr.bin.evince /etc/apparmor.d/cache/usr.lib.telepathy /etc/apparmor.d/cache/usr.sbin.cupsd /etc/apparmor.d/cache/usr.sbin.tcpdump /etc/apt/trustdb.gpg /etc/at.deny /etc/ati/inst_path_default /etc/ati/inst_path_override /etc/chatscripts /etc/cups/ssl /etc/cups/subscriptions.conf /etc/cups/subscriptions.conf.O /etc/default/cacerts /etc/fuse.conf /etc/group- /etc/gshadow /etc/gshadow- /etc/mtab.fuselock /etc/passwd- /etc/ppp/chap-secrets /etc/ppp/pap-secrets /etc/ppp/peers /etc/security/opasswd /etc/shadow /etc/shadow- /etc/ssl/private /etc/sudoers /etc/sudoers.d/README /etc/ufw/after.rules /etc/ufw/after6.rules /etc/ufw/before.rules /etc/ufw/before6.rules /lib/ufw/user.rules /lib/ufw/user6.rules /lost+found /root /run/crond.reboot /run/cups/certs /run/lightdm /run/lock/whoopsie/lock /run/udisks /var/backups/group.bak /var/backups/gshadow.bak /var/backups/passwd.bak /var/backups/shadow.bak /var/cache/apt/archives/lock /var/cache/cups/job.cache /var/cache/cups/job.cache.O /var/cache/cups/ppds.dat /var/cache/debconf/passwords.dat /var/cache/ldconfig /var/cache/lightdm/dmrc /var/crash/_usr_lib_x86_64-linux-gnu_colord_colord.102.crash /var/lib/apt/lists/lock /var/lib/dpkg/lock /var/lib/dpkg/triggers/Lock /var/lib/lightdm /var/lib/mlocate/mlocate.db /var/lib/polkit-1 /var/lib/sudo /var/lib/urandom/random-seed /var/lib/ureadahead/pack /var/lib/ureadahead/run.pack /var/log/btmp /var/log/installer/casper.log /var/log/installer/debug /var/log/installer/partman /var/log/installer/syslog /var/log/installer/version /var/log/lightdm/lightdm.log /var/log/lightdm/x-0-greeter.log /var/log/lightdm/x-0.log /var/log/speech-dispatcher /var/log/upstart/alsa-restore.log /var/log/upstart/alsa-restore.log.1.gz /var/log/upstart/console-setup.log /var/log/upstart/console-setup.log.1.gz /var/log/upstart/container-detect.log /var/log/upstart/container-detect.log.1.gz /var/log/upstart/hybrid-gfx.log /var/log/upstart/hybrid-gfx.log.1.gz /var/log/upstart/modemmanager.log /var/log/upstart/modemmanager.log.1.gz /var/log/upstart/module-init-tools.log /var/log/upstart/module-init-tools.log.1.gz /var/log/upstart/procps-static-network-up.log /var/log/upstart/procps-static-network-up.log.1.gz /var/log/upstart/procps-virtual-filesystems.log /var/log/upstart/procps-virtual-filesystems.log.1.gz /var/log/upstart/rsyslog.log /var/log/upstart/rsyslog.log.1.gz /var/log/upstart/ureadahead.log /var/log/upstart/ureadahead.log.1.gz /var/spool/anacron/cron.daily /var/spool/anacron/cron.monthly /var/spool/anacron/cron.weekly /var/spool/cron/atjobs /var/spool/cron/atspool /var/spool/cron/crontabs /var/spool/cups

• Reminder: Benefícios da Virtualização para ISVs - 14/Dez/10, Porto

  - by Paulo Folgado

  Esta formação aborda as principais dificuldades com que os Independent Software Vendors (ISVs) se confrontam quando têm de escolher as plataformas sobre as quais irão certificar, instalar e suportar as suas aplicações, e como o Oracle VM (e o Oracle Enterprise Linux) os podem ajudar a ultrapassar essas dificuldades. O modelo de negócio clássico de um ISV - desenvolver uma solução aplicacional para resolver um determinado problema de negócio, analizar o mercado para determinar quais os sistemas operativos e o hardware que os clientes do seu mercado alvo usam, e decidir suportar as plataformas hardware e software que 80% dos seus clientes do seu mercado alvo usam (e tratar como excepções outras configurações que lhe sejam solicitadas por alguns clientes importantes) - funcionou bem no anos 80 e princípios dos anos 90, quando havia uma menor diversidade de plataformas. Contudo, com o aparecimentos nos últimos anos de múltiplas versões de sistemas operativos e de "sabores" Linux, este modelo começou a tornar-se um pesadelo. Cada cliente tem a sua plataforma de eleição e espera dos ISV que suportem essas suas opções, o que constitui um sorvedouro dos recursos e dos custos dos ISVs. As tecnologias de virtualização da Oracle, ao permitirem "simular" uma determinada configuração de hardware, fazendo com que o sistema operativo "pense" que está correr numa configuração de hardware pré-definida e normalizada, na qual correm as aplicações, constituem um veículo excelente para os ISVs que procuram uma solução simples, fácil de instalar e fácil de suportar para instalação das suas aplicações, permitindo obter grandes economias de custos em termos de desenvolvimento, teste e suporte dessas aplicações. Quem deve assistir? Esta formação dirige-se sobretudo a quem que tomar decisões sobre as plataformas tecnológicas que o ISV tem de suportar, assim como a quem lida com a estrutura de custos da suas operações, com uma visão dos custos associados ao desenvolvimento, certificação, instalação e suporte de múltiplas plataformas. Se quer saber mais sobre o Oracle VM e como ele pode ajudar a reduzir drasticamente os sues custos, não perca esta formação. AGENDA: 09:00 Welcome & Introduction  ISV Partner View...

• A Forming Repository of Script Samples for Automating Windows Server 2012 and Windows 8

  - by Jialiang

  Compared with Windows Server 2008/R2 that provides about 230 cmdlets, Windows Server 2012 beats that by a factor of over 10 shipping ~ 2,430 cmdlets.  You can automate almost every aspect of the server.   The new PowerShell 3.0, like Windows Server 2012, has a ton of new features.  In this automation script-centric move, Microsoft All-In-One Script Framework (AIOSF) is ready to support IT Pros with many new services and offerings coming this year.  We sincerely hope that the IT community will benefit from the effort. Here is the first one among our new services and offerings:  The team is preparing a large set of Windows 8 / Windows Server 2012 script samples based on frequently asked IT tasks that we collect in TechNet forums and support calls to Microsoft.   Because the script topics come from frequently asked IT tasks, we hope that these script samples can be helpful to many IT Pros worldwide.   With the General Availability of Windows Server 2012, we release the first three Windows Server 2012 / Windows 8 script samples today.    Get Network Adapter Properties in Windows Server 2012 and Windows 8 (PowerShell) http://gallery.technet.microsoft.com/scriptcenter/Get-Network-Adapter-37c5a913 Description: This script could be used to get network adapter properties and advanced properties in Windows Server 2012 and Windows 8. It combines the outputs of Get-NetAdapter and Get-NetAdapterAdvancedProperty. It can generate a report of network adapter configuration settings. Use Scenarios: In a real world, IT Administrators are required to check the configuration of network adapters after the deployment of new servers. One typical example is the duplex setting of network adapters. Also, IT administrators need to maintain a server list which contains network adapter configuration settings in a regular basis. Before Windows Server 2012, IT administrators often feel difficulties to handle these tasks. Acknowledgement: Thanks Greg Gu from AIOSF for collecting this script topic, and writing the script sample.  Thanks James Adams (Microsoft Premier Field Engineer) for reviewing the script sample and ensuring its quality.   How to batch create virtual machines in Windows Server 2012 (PowerShell) http://gallery.technet.microsoft.com/scriptcenter/How-to-batch-create-9efd1811 Description: This PowerShell Script illustrates how to batch create multiple virtual machines based on comma delimited file by using PowerShell 3.0 in Windows Server 2012. Use Scenarios: IT admin requires to batch creating virtual machines in Windows Server 2012, although they can use few commands due to the lack of programming knowledge. Although it’s a set of Hyper-V command-lets within Windows PowerShell, IT Admins are reluctant to use them except simple a command which is widely used. Acknowledgement: Thanks Anders Wang from AIOSF for collecting this script topic and writing the script sample.  Thanks Christopher Norris for reviewing the script sample and ensuring its quality before publishing.   Remove Windows Store Apps in Windows 8 (PowerShell) http://gallery.technet.microsoft.com/scriptcenter/Remove-Windows-Store-Apps-a00ef4a4 Description: This script can be used to remove multiple Windows Store Apps from a user account in Windows 8. It provides a list of installed Windows Store applications. You can specify the application IDs, and remove them all at once. Use Scenarios: 1. In Windows 8, you can remove a single Windows Store App by right-clicking the tile in the Start menu and choosing the uninstall command.  However, no command is provided for removing multiple Windows Store Apps all at once. If you want to do so, you can use this script sample. 2. Sometimes Windows Store Apps may crash in Windows 8.  Even though you can successfully uninstall and reinstall the App, the application may still crash after the reinstallation.  In this situation, you can use this example script to remove these Windows Store Apps cleanly. Acknowledgement: Thanks Edward Qi from AIOSF for collecting the script idea and composing the script sample.  Thanks James Adams (Microsoft Premier Field Engineer) for reviewing the script sample and ensuring its quality.   This is just the beginning, and more and more script samples are coming.  You can follow our blog (http://blogs.technet.com/b/onescript) to get the latest customer-driven script samples for Windows Server 2012 and Windows 8.

• How to set default xrandr settings?

  - by echo-flow

  I'm trying to enable dual monitors in Ubuntu. This is working fine, but every time I do it, desktop effects is disabled. I think I've found the reason why, though: https://wiki.ubuntu.com/X/Config/Multihead/ As with the GNOME XRandR configuration method, setting Virtual to too large a value may result in a loss of hardware acceleration, and thus an inability to use Compiz and its desktop effects. When I use the GNOME monitor applet, or the Monitors configuration in the System menu, the default xrandr settings puts the second monitor to the right of the first, and, as I found with this bug, for most monitors this creates a virtual desktop larger than the maximum 2048 horizontal resolution needed for hardware acceleration on my netbook hardware. So, it seems like if I can modify xrandr's default settings so that it places the new desktop above or below (north or south of) the main LVDS display, then hardware acceleration, and therefore compiz will continue to work. Can anyone tell me, what is the easiest way to achieve this? UPDATE: I have confirmed that multihead support with desktop effects and hardware acceleration works when I move the external monitor display north of the main LVDS display. Right now this involves the following process: plugging in the external monitor, starting the Monitors configuration menu, desktop effects are disabled automatically (and all of the windows on my workspaces are moved to the first workspace), repositioning the external display so that it is north of LVDS display and clicking apply, and then navigating to the Appearance menu and telling it to reenable desktop effects. Is there a simpler way do this? UPDATE 2: OK, so I thought that perhaps the GNOME Monitors configuration screen was trying to be clever, and might be disbling desktop effects. So, I just tried using the xrandr command-line client instead, as follows: xrandr --output VGA1 --above LVDS1 When I do that, desktop effects are still disabled, and I need to manually reenable them. This, despite the fact that hardware acceleration works, and there is never a point where hardware acceleration stops working because the horizontal dimension of the virtual display is too large. So what program is trying to be clever, and is turning off desktop effects when it doesn't need to? And how do I make it stop? If there were a way to re-enable desktop effects from the command line, which I could then put into a script along with the proper xrandr invocation, I would accept that as a workaround. UPDATE 3: OK, here's my script to enable a second monitor with desktop effects.

• Windows Azure SDK 1.3 addresses early adopter feedback

  - by Eric Nelson

  At the end of November 2010 we released a new version of the Windows Azure SDK which contains many new features driven by the great feedback of early adopters plus a shiny new portal. New Portal implemented in Silverlight: The new portal is implemented using Silverlight and replaces the (IMHO rather clunky) original HTML + JavaScript portal. It is 100% better although does still have a few bugs. Enjoy! P.S. You can if you wish still use the old portal:   New runtime functionality: The following functionality is now generally available through the Windows Azure SDK and Windows Azure Tools for Visual Studio and the new Windows Azure Management Portal: Elevated Privileges and Full IIS. You can now run a portion or all of your code in Web and Worker roles with elevated administrator privileges. The Web role now provides Full IIS functionality, which enables multiple IIS sites per Web role and the ability to install IIS modules. Remote Desktop functionality enables you to connect to a running instance of your application or service in order to monitor activity and troubleshoot common problems. Windows Server 2008 R2 Roles: Windows Azure now supports Windows Server 2008 R2 in its Web, worker and VM roles. This new support enables you to take advantage of the full range of Windows Server 2008 R2 features such as IIS 7.5, AppLocker, and enhanced command-line and automated management using PowerShell Version 2.0. New runtime functionality – in beta: Windows Azure Virtual Machine Role: Support for more types of new and existing Windows applications will soon be available with the introduction of the Virtual Machine (VM) role. You can move more existing applications to Windows Azure, reducing the need to make costly code or deployment changes. Extra Small Windows Azure Instance, which is priced at $0.05 per compute hour, provides developers with a cost-effective training and development environment. Developers can also use the Extra Small instance to prototype cloud solutions at a lower cost. Windows Azure Connect: (formerly Project Sydney), which enables a simple and easy-to-manage mechanism to set up IP-based network connectivity between on-premises and Windows Azure resources, is the first Windows Azure Virtual Network feature that we’re making available as a CTP. You can sign up for any of the betas via the Windows Azure Management Portal. Improved processes and simplified operations New portal! (see above) Access to new diagnostic information including the ability to click on a role to see role type, deployment time and last reboot time A new sign-up process that dramatically reduces the number of steps needed to sign up for Windows Azure. New scenario based Windows Azure Platform forums to help answer questions and share knowledge more efficiently. Multiple Service Administrators: Windows Azure now supports multiple Windows Live IDs to have administrator privileges on the same Windows Azure account. The objective is to make it easy for a team to work on the same Windows Azure account while using their individual Windows Live IDs.   Related Links Please also let us know through Microsoft Platform Ready if and when you intend to build an application using the Windows Azure Platform. Or indeed if you already have (Well done). You will get access to some great benefits if you do (more on that in a future post). It also really helps us better understand the demand out there which directly impacts how we will plan the next six months of activities around the Windows Azure Platform.

• Best Practices - Core allocation

  - by jsavit

  This post is one of a series of "best practices" notes for Oracle VM Server for SPARC (also called Logical Domains) Introduction SPARC T-series servers currently have up to 4 CPU sockets, each of which has up to 8 or (on SPARC T3) 16 CPU cores, while each CPU core has 8 threads, for a maximum of 512 dispatchable CPUs. The defining feature of Oracle VM Server for SPARC is that each domain is assigned CPU threads or cores for its exclusive use. This avoids the overhead of software-based time-slicing and emulation (or binary rewriting) of system state-changing privileged instructions used in traditional hypervisors. To create a domain, administrators specify either the number of CPU threads or cores that the domain will own, as well as its memory and I/O resources. When CPU resources are assigned at the individual thread level, the logical domains constraint manager attempts to assign threads from the same cores to a domain, and avoid "split core" situations where the same CPU core is used by multiple domains. Sometimes this is unavoidable, especially when domains are allocated and deallocated CPUs in small increments. Why split cores can matter Split core allocations can silenty reduce performance because multiple domains with different address spaces and memory contents are sharing the core's Level 1 cache (L1$). This is called false cache sharing since even identical memory addresses from different domains must point to different locations in RAM. The effect of this is increased contention for the cache, and higher memory latency for each domain using that core. The degree of performance impact can be widely variable. For applications with very small memory working sets, and with I/O bound or low-CPU utilization workloads, it may not matter at all: all machines wait for work at the same speed. If the domains have substantial workloads, or are critical to performance then this can have an important impact: This blog entry was inspired by a customer issue in which one CPU core was split among 3 domains, one of which was the control and service domain. The reported problem was increased I/O latency in guest domains, but the root cause might be higher latency servicing the I/O requests due to the control domain being slowed down. What to do about it Split core situations are easily avoided. In most cases the logical domain constraint manager will avoid it without any administrative action, but it can be entirely prevented by doing one of the several actions: Assign virtual CPUs in multiples of 8 - the number of threads per core. For example: ldm set-vcpu 8 mydomain or ldm add-vcpu 24 mydomain. Each domain will then be allocated on a core boundary. Use the whole core constraint when assigning CPU resources. This allocates CPUs in increments of entire cores instead of virtual CPU threads. The equivalent of the above commands would be ldm set-core 1 mydomain or ldm add-core 3 mydomain. Older syntax does the same thing by adding the -c flag to the add-vcpu, rm-vcpu and set-vcpu commands, but the new syntax is recommended. When whole core allocation is used an attempt to add cores to a domain fails if there aren't enough completely empty cores to satisfy the request. See https://blogs.oracle.com/sharakan/entry/oracle_vm_server_for_sparc4 for an excellent article on this topic by Eric Sharakan. Don't obsess: - if the workloads have minimal CPU requirements and don't need anywhere near a full CPU core, then don't worry about it. If you have low utilization workloads being consolidated from older machines onto a current T-series, then there's no need to worry about this or to assign an entire core to domains that will never use that much capacity. In any case, make sure the most important domains have their own CPU cores, in particular the control domain and any I/O or service domain, and of course any important guests. Summary Split core CPU allocation to domains can potentially have an impact on performance, but the logical domains manager tends to prevent this situation, and it can be completely and simply avoided by allocating virtual CPUs on core boundaries.

• Strategies for invoking subclass methods on generic objects

  - by Brad Patton

  I've run into this issue in a number of places and have solved it a bunch of different ways but looking for other solutions or opinions on how to address. The scenario is when you have a collection of objects all based off of the same superclass but you want to perform certain actions based only on instances of some of the subclasses. One contrived example of this might be an HTML document made up of elements. You could have a superclass named HTMLELement and subclasses of Headings, Paragraphs, Images, Comments, etc. To invoke a common action across all of the objects you declare a virtual method in the superclass and specific implementations in all of the subclasses. So to render the document you could loop all of the different objects in the document and call a common Render() method on each instance. It's the case where again using the same generic objects in the collection I want to perform different actions for instances of specific subclass (or set of subclasses). For example (an remember this is just an example) when iterating over the collection, elements with external links need to be downloaded (e.g. JS, CSS, images) and some might require additional parsing (JS, CSS). What's the best way to handle those special cases. Some of the strategies I've used or seen used include: Virtual methods in the base class. So in the base class you have a virtual LoadExternalContent() method that does nothing and then override it in the specific subclasses that need to implement it. The benefit being that in the calling code there is no object testing you send the same message to each object and let most of them ignore it. Two downsides that I can think of. First it can make the base class very cluttered with methods that have nothing to do with most of the hierarchy. Second it assumes all of the work can be done in the called method and doesn't handle the case where there might be additional context specific actions in the calling code (i.e. you want to do something in the UI and not the model). Have methods on the class to uniquely identify the objects. This could include methods like ClassName() which return a string with the class name or other return values like enums or booleans (IsImage()). The benefit is that the calling code can use if or switch statements to filter objects to perform class specific actions. The downside is that for every new class you need to implement these methods and can look cluttered. Also performance could be less than some of the other options. Use language features to identify objects. This includes reflection and language operators to identify the objects. For example in C# there is the is operator that returns true if the instance matches the specified class. The benefit is no additional code to implement in your object hierarchy. The only downside seems to be the lack of using something like a switch statement and the fact that your calling code is a little more cluttered. Are there other strategies I am missing? Thoughts on best approaches?

• Getting Started with Cloud Computing

  - by juanlarios

  You’ve likely heard about how Office 365 and Windows Intune are great applications to get you started with Cloud Computing. Many of you emailed me asking for more info on what Cloud Computing is, including the distinction between "Public Cloud" and "Private Cloud". I want to address these questions and help you get started. Let's begin with a brief set of definitions and some places to find more info; however, an excellent place where you can always learn more about Cloud Computing is the Microsoft Virtual Academy. Public Cloud computing means that the infrastructure to run and manage the applications users are taking advantage of is run by someone else and not you. In other words, you do not buy the hardware or software to run your email or other services being used in your organization – that is done by someone else. Users simply connect to these services from their computers and you pay a monthly subscription fee for each user that is taking advantage of the service. Examples of Public Cloud services include Office 365, Windows Intune, Microsoft Dynamics CRM Online, Hotmail, and others. Private Cloud computing generally means that the hardware and software to run services used by your organization is run on your premises, with the ability for business groups to self-provision the services they need based on rules established by the IT department. Generally, Private Cloud implementations today are found in larger organizations but they are also viable for small and medium-sized businesses since they generally allow an automation of services and reduction in IT workloads when properly implemented. Having the right management tools, like System Center 2012, to implement and operate Private Cloud is important in order to be successful. So – how do you get started? The first step is to determine what makes the most sense to your organization. The nice thing is that you do not need to pick Public or Private Cloud – you can use elements of both where it makes sense for your business – the choice is yours. When you are ready to try and purchase Public Cloud technologies, the Microsoft Volume Licensing web site is a good place to find links to each of the online services. In particular, if you are interested in a trial for each service, you can visit the following pages: Office 365, CRM Online, Windows Intune, and Windows Azure. For Private Cloud technologies, start with some of the courses on Microsoft Virtual Academy and then download and install the Microsoft Private Cloud technologies including Windows Server 2008 R2 Hyper-V and System Center 2012 in your own environment and take it for a spin. Also, keep up to date with the Canadian IT Pro blog to learn about events Microsoft is delivering such as the IT Virtualization Boot Camps and more to get you started with these technologies hands on. Finally, I want to ask for your help to allow the team at Microsoft to continue to provide you what you need. Twice a year through something we call "The Global Relationship Study" – they reach out and contact you to see how they're doing and what Microsoft could do better. If you get an email from "Microsoft Feedback" with the subject line "Help Microsoft Focus on Customers and Partners" between March 5th and April 13th, please take a little time to tell them what you think. Cloud Computing Resources: Microsoft Server and Cloud Computing site – information on Microsoft's overall cloud strategy and products.

Here's the GUI error (from Directory Utility) on the OS X client: Here's the GUI error (from User's and Groups) in System Preferences on the OS X client: Update After some Wiresharking I've got some more info: OS X Client - KDC (over UDP): AS_REQ (no padata) OS X Client <- KDC (over UDP): KRB5KDC_ERR_PREAUTH_REQUIRED OS X Client - KDC (over UDP): AS_REQ (this time with PA-ENC-TIMESTAMP in padata) OS X Client <- KDC (over UDP): KRB5KDC_ERR_RESPONSE_TOO_BIG OS X Client - KDC (over TCP): AS_REQ (also with PA-ENC-TIMESTAMP in padata) OS X Client <- KDC (over TCP): KDC_ERR_ETYPE_NOSUPP ...and that's it. This is what I think is going on: The OS X client sends a kerberos request. The KDC says, "You need to pre-authenticate. Try again" The OS X client tries to pre-authenticate (all this so far is over UDP) Something gets lost on our network and the KDC says, "Oops something went wrong" The OS X client switches to TCP and tries again. Over TCP, the KDC says, "You're using an encryption type I don't support" Note that in its padata records, the OS X client is always using "aes256-cts-hmac-sha1-96" as its encryption type. However, in its KDC_REQ_BODY record it lists the aes256-cts-hmac-sha1-96, aes128-cts-hmac-sha1-96, des3-cbc-sha1, and rc4-hmac encryption types. When the KDC comes back with KDC_ERR_ETYPE_NOSUPP, it uses rc4-hmac as its encryption type in its padata record. I know next to nothing about Kerberos, but it seems to me that the OS X client should go ahead and try the rc4-hmac encryption type. However, it does nothing after this. Update 2 Here's the debug log from Directory Services on the OS X client.

• Setting up Group Managed Service Account on Windows Server 2012 R2

  - by Moo MinTroll

  I have a Windows 2012 R2 domain controller called cox.win.testlab. I have set up a group of hosts where I would like to use a gMSA (Group Managed Service Account). This group is called SQLManagedHosts. I created the account by following these steps in Powershell on the domain controller: PS C:\Windows\system32> Add-KdsRootKey -EffectiveTime ((get-date).addhours(-10)) Guid ---- 9b68b1e7-db76-c4e4-4978-63c2965e5596 PS C:\Windows\system32> New-ADServiceAccount mSQL -DNSHostName cox.win.testlab -PrincipalsAllowedToRetrieveManagedPassword SQLManagedHosts PS C:\Windows\system32> Get-ADServiceAccount msql DistinguishedName : CN=mSQL,CN=Managed Service Accounts,DC=win,DC=testlab Enabled : True Name : mSQL ObjectClass : msDS-GroupManagedServiceAccount ObjectGUID : cf9df74a-38e0-4d7a-856e-9af882b08800 SamAccountName : mSQL$ SID : S-1-5-21-3443997112-87545443-1733229669-1602 UserPrincipalName : On one of the hosts listed in SQLManagedHosts, I ran: PS C:\Windows\system32> Install-ADServiceAccount msql Install-ADServiceAccount : Cannot install service account.

• mount.nfs: access denied by server while mounting (null), can't find any log information

  - by Mark0978

  Two ubuntu servers: 10.0.8.2 is the client, 192.168.20.58 is the server. Between the 2 machines, Ping works, ssh works (in both directions). From 10.0.8.2 showmount -e 192.168.20.58 Export list for 192.168.20.58: /imr/nfsshares/foobar 10.0.8.2 mount.nfs 192.168.20.58:/imr/nfsshares/foobar /var/data/foobar -v mount.nfs: access denied by server while mounting (null) Found several things online, tried them all and still can't find any log information anywhere. On the server: [email protected]:/var/log# cat /etc/hosts.allow sendmail: all ALL: 10.0.8.2 /etc/hosts.deny is all comments How can I get a trail of log statements to figure this out?

• SCVMM 2008 R2 problems migrating VM from VS2005 to Hyper-V host

  - by Scott Ivey

  I have System Center Virtual Machine Manager 2008 R2 installed, and have a Hyper-V R2 host and a Virtual Server 2005 host. I'm trying to migrate my machines from the VS2005 host to the Hyper-V host, and keep getting the following error... VMM is unable to complete the requested file transfer. The connection to the HTTP server myserver.mydomain.local could not be established. (Unknown error (0x80072efd)) Recommended Action Ensure that the HTTP service and/or the agent on the machine myserver.mydomain.local are installed and running and that a firewall is not blocking HTTPS traffic. (Note - migrations between Hyper-V hosts managed by the VMM server work fine - my problem is just going from VS2005-Hyper-V hosts) I have no firewalls turned on on either of the servers, and no firewalls in the middle. I've looked all over for answers to this problem, and am getting nowhere. All the articles I find when searching are talking about either V2V or P2V - and i'm just trying to do a straight migrate VM. I've tried rebooting the boxes, changing the BITS SSL port number, restarting services, triple-checking firewalls, etc. Does anyone have any good suggestions as to how I can resolve this problem?

• iMac OSX "no route to host"

  - by jairo

  I have an issue with one of my computer on my network. It is an iMac running OS X 10.5.8. The issue is accessing certain websites. For instance, one of these websites is that the computer is unable to connect to is farmville.com. When I ping farmville.com it returns "no route to host": $ ping farmville.com PING farmville.com (50.16.253.102): 56 data bytes ping: sendto: No route to host ping: sendto: No route to host ping: sendto: No route to host When I traceroute farmville: $ traceroute farmville.com traceroute: Warning: farmville.com has multiple addresses; using 50.16.253.109 traceroute to farmville.com (50.16.253.109), 64 hops max, 40 byte packets traceroute: sendto: No route to host 1 traceroute: wrote farmville.com 40 chars, ret=-1 tracerouting the farmville ip address: 50.16.253.109 $ traceroute 50.16.253.109 traceroute to farmville.com (50.16.253.109), 64 hops max, 40 byte packets traceroute: sendto: No route to host 1 traceroute: wrote farmville.com 40 chars, ret=-1 Now the interesting part is that I on another computer (running Ubuntu 10.10) I have no issues at all accessing this website. Which tells me that it's not the internet connection. I've also disabled the firewall on the router to no avail. The /etc/hosts file in the mac is the following. The /private/etc/hosts file is empty: ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost #255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost Any help is appreciated. Many thanks

• Authenticating Windows 7 against MIT Kerberos 5

  - by tommed

  Hi There, I've been wracking my brains trying to get Windows 7 authenticating against a MIT Kerberos 5 Realm (which is running on an Arch Linux server). I've done the following on the server (aka dc1): Installed and configured a NTP time server Installed and configured DHCP and DNS (setup for the domain tnet.loc) Installed Kerberos from source Setup the database Configured the keytab Setup the ACL file with: *@TNET.LOC * Added a policy for my user and my machine: addpol users addpol admin addpol hosts ank -policy users [email protected] ank -policy admin tom/[email protected] ank -policy hosts host/wdesk3.tnet.loc -pw MYPASSWORDHERE I then did the following to the windows 7 client (aka wdesk3): Made sure the ip address was supplied by my DHCP server and dc1.tnet.loc pings ok Set the internet time server to my linux server (aka dc1.tnet.loc) Used ksetup to configure the realm: ksetup /SetRealm TNET.LOC ksetup /AddKdc dc1.tnet.loc ksetip /SetComputerPassword MYPASSWORDHERE ksetip /MapUser * * After some googl-ing I found that DES encryption was disabled by Windows 7 by default and I turned the policy on to support DES encryption over Kerberos Then I rebooted the windows client However after doing all that I still cannot login from my Windows client. :( Looking at the logs on the server; the request looks fine and everything works great, I think the issue is that the response from the KDC is not recognized by the Windows Client and a generic login error appears: "Login Failure: User name or password is invalid". The log file for the server looks like this (I tail'ed this so I know it's happening when the Windows machine attempts the login): Screen-shot: http://dl.dropbox.com/u/577250/email/login_attempt.png If I supply an invalid realm in the login window I get a completely different error message, so I don't think it's a connection problem from the client to the server? But I can't find any error logs on the Windows machine? (anyone know where these are?) If I try: runas /netonly /user:[email protected] cmd.exe everything works (although I don't get anything appear in the server logs, so I'm wondering if it's not touching the server for this??), but if I run: runas /user:[email protected] cmd.exe I get the same authentication error. Any Kerberos Gurus out there who can give me some ideas as to what to try next? pretty please?
