• Advice needed on Process - Service Design

  - by user99314

  Need some advice from experts on designing a flow. Create a service that will read a csv file which may contain anywhere over 6000+ rows of individual ids as shown in the sample below. Need to read that file and go to oracle database and fetch a vname,vnumber,vid of each id in the csv and then go to document repository i.e. Oracle UCM and download all documents matching vname,vnumber,vid there can be =0 documents for each vname,vnumber,vid and save them on a file system. UCM exposes a webservice to dowload the documents. Finally create a new csv appending the filenames that are downloaded for each id. Need to keep track of any errors but need to make sure to go over the whole ids in the csv to download the documents and skip in case of errors. Need some advice on how to go about designing this as there may be over 6000+ rows in a csv file and looping it and hitting the database for each individual id and then hitting a UCM may be a bit expensive so open for any idea. How to go by designing this solution. Wondering if messaging can be helpful here or offloading process of getting the vname,vnumber,vid to pl/sql packages, creating staging tables etc. Initial csv that contains ids: **ID** 12345a 12s345 3456fr we9795 we9797 Final csv output: **ID Files Downloaded from UCM** 12345a a.pdf,b.doc,d.txt 12s345 a1.pdf,s2.pdf,f4.gif 3456fr b.xls we9795 we9797 x.doc Thanks

• Recursive XML through XSLT to XML

  - by Patrick

  Essentially, I have XML structured like this: <A> <B> <1>data</1> <2>data</2> <C> <1>data</1> <2>data</2> <B> <1>data</1> <2>data</2> <C> <B> <1>data</1> <2>data</2> </B> </C> </B> <B> <1>data</1> <2>data</2> </B> </C> </B> </A> I am trying to get the output to look like this: <A> <B 1="data" 2="data"> <C 1="data" 2="data"> <B 1="data" 2="data"> <C> <B 1="data" 2="data" > </B> </C> </B> <B 1="data" 2="data" > </B> </C> </B> </A> I have figured out how to put everything as attributes and start looping through the elements. The issue I am facing is that when trying to get below the first C, nothing happens. Here is my code: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"> <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <MenuDataResult> <B> <xsl:apply-templates /> </B> </MenuDataResult> </xsl:template> <xsl:template match="B"> <xsl:for-each select="B"> <B ItemID="{B/ItemID/text()}" ItemType="{ItemType/text()}" ItemSubType="{ItemSubType/text()}" ItemTitle="{ItemTitle/text()}" ItemImage="{ItemImage/text()}" ItemImageOverride="{ItemImageOverride/text()}" ItemLink="{ItemLink/text()}" ItemTarget="{ItemTarget/text()}>"> <xsl:for-each select="C"> <xsl:apply-templates select="C"/> </xsl:for-each> </B> </xsl:for-each> </xsl:template> <xsl:template match="C"> <C ID="{ID/text()}" Title="{Title/text()}" Template="{Template/text()}" Type="{Type/text()}" Link="{Link/text()}" ParentID="{ParentID/text()}" AncestorID="{AncestorID/text()}" FolderID="{FolderID/text()}" Description="{Description/text()}" Image="{Image/text()}" ImageOverride="{ImageOverride/text()}"> <xsl:for-each select="B"> <xsl:apply-templates select=".//B"/> </xsl:for-each> </C> </xsl:template> </xsl:stylesheet>

• Why is the this-pointer needed to access inherited attributes?

  - by Shadow

  Hi, assume the following class is given: class Base{ public: Base() {} Base( const Base& b) : base_attr(b.base_attr) {} void someBaseFunction() { .... } protected: SomeType base_attr; }; When I want a class to inherit from this one and include a new attribute for the derived class, I would write: class Derived: public Base { public: Derived() {} Derived( const Derived& d ) : derived_attr(d.derived_attr) { this->base_attr = d.base_attr; } void SomeDerivedFunction() { .... } private: SomeOtherType derived_attr; }; This works for me (let's ignore eventually missing semicolons or such please). However, when I remove the "this-" in the copy constructor of the derived class, the compiler complains that "'base_attr' was not declared in this scope". I thought that, when inheriting from a class, the protected attributes would then also be accessible directly. I did not know that the "this-" pointer was needed. I am now confused if it is actually correct what I am doing there, especially the copy-constructor of the Derived-class. Because each Derived object is supposed to have a base_attr and a derived_attr and they obviously need to be initialized/set correctly. And because Derived is inheriting from Base, I don't want to explicitly include an attribute named "base_attr" in the Derived-class. IMHO doing so would generally destroy the idea behind inheritance, as everything would have to be defined again. EDIT Thank you all for the quick answers. I completely forgot the fact that the classes actually are templates. Please, see the new examples below, which are actually compiling when including "this-" and are failing when omiting "this-" in the copy-constructor of the Derived-class: Base-class: #include <iostream> template<class T> class Base{ public: Base() : base_attr(0) {} Base( const Base& b) : base_attr(b.base_attr) {} void baseIncrement() { ++base_attr; } void printAttr() { std::cout << "Base Attribute: " << base_attr << std::endl; } protected: T base_attr; }; Derived-class: #include "base.hpp" template< class T > class Derived: public Base<T>{ public: Derived() : derived_attr(1) {} Derived( const Derived& d) : derived_attr(d.derived_attr) { this->base_attr = d.base_attr; } void derivedIncrement() { ++derived_attr; } protected: T derived_attr; }; and for completeness also the main function: #include "derived.hpp" int main() { Derived<int> d; d.printAttr(); d.baseIncrement(); d.printAttr(); Derived<int> d2(d); d2.printAttr(); return 0; }; I am using g++-4.3.4. Although I understood now that it seems to come from the fact that I use template-class definitions, I did not quite understand what is causing the problem when using templates and why it works when not using templates. Could someone please further clarify this?

• How to use XSLT to tag specific nodes with unique, sequential, increasing integer ids?

  - by ~otakuj462

  Hi, I'm trying to use XSLT to transform a document by tagging a group of XML nodes with integer ids, starting at 0, and increasing by one for each node in the group. The XML passed into the stylesheet should be echoed out, but augmented to include this extra information. Just to be clear about what I am talking about, here is how this transformation would be expressed using DOM: states = document.getElementsByTagName("state"); for( i = 0; i < states.length; i++){ states.stateNum = i; } This is very simple with DOM, but I'm having much more trouble doing this with XSLT. The current strategy I've devised has been to start with the identity transformation, then create a global variable which selects and stores all of the nodes that I wish to number. I then create a template that matches that kind of node. The idea, then, is that in the template, I would look up the matched node's position in the global variable nodelist, which would give me a unique number that I could then set as an attribute. The problem with this approach is that the position function can only be used with the context node, so something like the following is illegal: <template match="state"> <variable name="stateId" select="@id"/> <variable name="uniqueStateNum" select="$globalVariable[@id = $stateId]/position()"/> </template> The same is true for the following: <template match="state"> <variable name="stateId" select="@id" <variable name="stateNum" select="position($globalVariable[@id = $stateId])/"/> </template> In order to use position() to look up the position of an element in $globalVariable, the context node must be changed. I have found a solution, but it is highly suboptimal. Basically, in the template, I use for-each to iterate through the global variable. For-each changes the context node, so this allows me to use position() in the way I described. The problem is that this turns what would normally be an O(n) operation into an O(n^2) operation, where n is the length of the nodelist, as this require iterating through the whole list whenever the template is matched. I think that there must be a more elegant solution. Altogether, here is my current (slightly simplified) xslt stylesheet: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:s="http://www.w3.org/2005/07/scxml" xmlns="http://www.w3.org/2005/07/scxml" xmlns:c="http://msdl.cs.mcgill.ca/" version="1.0"> <xsl:output method="xml"/> <!-- we copy them, so that we can use their positions as identifiers --> <xsl:variable name="states" select="//s:state" /> <!-- identity transform --> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="s:state"> <xsl:variable name="stateId"> <xsl:value-of select="@id"/> </xsl:variable> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:for-each select="$states"> <xsl:if test="@id = $stateId"> <xsl:attribute name="stateNum" namespace="http://msdl.cs.mcgill.ca/"> <xsl:value-of select="position()"/> </xsl:attribute> </xsl:if> </xsl:for-each> <xsl:apply-templates select="node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> I'd appreciate any advice anyone can offer. Thanks.

• Create a named cell dynamically

  - by CaptMorgan

  I have a workbook with 3 worksheets. 1 worksheet will have input values (not created at the moment and not needed for this question), 1 worksheet with several "template" or "source" tables, and the last worksheet has 4 formatted "target" tables (empty or not doesn't matter). Each template table has 3 columns, 1 column identifying what the values are for in the second 2 columns. The value columns have formulas in them and each cell is Named. The formulas use the cell Names rather than cell address (e.g. MyData1 instead of C2). I am trying to copy the templates into the target tables while also either copying the cell Names from the source into the targets or create the Names in the target tables based on the source cell Names. My code below I am creating the target names by using a "base" in the Name that will be changed depending on which target table it gets copied to. my sample tables have "Num0_" for a base in all the cell names (e.g. Num0_MyData1, Num0_SomeOtherData2, etc). Once the copy has completed the code will then name the cells by looking at the target Names (and address), replacing the base of the name with a new base, just adding a number of which target table it goes to, and replacing the sheet name in the address. Here's where I need help. The way I am changing that address will only work if my template and target are using the same cell addresses of their perspective sheets. Which they are not. (e.g. Template1 table has value cells, each named, of B2 thru C10, and my target table for the copy may be F52 thur G60). Bottom line I need to figure out how to copy those names over with the templates or name the cells dynamically by doing something like a replace where I am incrementing the address value based on my target table #...remember I have 4 target tables which are static, I will only copy to those areas. I am a newbie to vba so any suggestions or help is appreciated. NOTE: The copying of the table works as I want. It even names the cells (if the Template and Target Table have the same local worksheet cell address (e.g. C2) 'Declare Module level variables 'Variables for target tables are defined in sub's for each target table. Dim cellName As Name Dim newName As String Dim newAddress As String Dim newSheetVar Dim oldSheetVar Dim oldNameVar Dim srcTable1 Sub copyTables() newSheetVar = "TestSheet" oldSheetVar = "Templates" oldNameVar = "Num0_" srcTable1 = "TestTableTemplate" 'Call sub functions to copy tables, name cells and update functions. copySrc1Table copySrc2Table End Sub '****there is another sub identical to this one below for copySrc2Table. Sub copySrc1Table() newNameVar = "Num1_" trgTable1 = "SourceEnvTable1" Sheets(oldSheetVar).Select Range(srcTable1).Select Selection.Copy For Each cellName In ActiveWorkbook.Names 'Find all names with common value If cellName.Name Like oldNameVar & "*" Then 'Replace the common value with the update value you need newName = Replace(cellName.Name, oldNameVar, newNameVar) newAddress = Replace(cellName.RefersTo, oldSheetVar, newSheetVar) 'Edit the name of the name. This will change any formulas using this name as well ActiveWorkbook.Names.Add Name:=newName, RefersTo:=newAddress End If Next cellName Sheets(newSheetVar).Select Range(trgTable1).Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=False End Sub PING

• CSS + jQuery - Unable to perform .toggle() and repeated jQueryTemplate Item [I must warn you this is a bit overwhelming]

  - by user1027620

  Okay here we go: Stream.html (Template file) <div class="streamItem clearfix"> <input type="button" /> <div class="clientStrip"> <img src="" alt="${Sender}" /> </div> <div class="clientView"> <a href="#" class="clientName">${Sender}</a> <p>${Value}</p> <p>${DateTime}</p> <div class="itemGadgets"> <ul> <li class="toggleInput">Value</li> <li></li> </ul> </div> <div class="inputContainer"> <input type="text" value="" /> </div> </div> </div> <div class="spacer" /> Default.aspx (jQuery) $('.toggleInput').live('click', function () { $(this).parent().parent() .find('.inputContainer').toggle(); $(this).parent().parent().find('.inputContainer') .find('input[type=text]').focus(); }); Update: The above has been changed to: $('.toggleInput').live('click', function () { $(this).closest(".clientView").find(".inputContainer").toggle() $(this).closest(".clientView").find(".inputContainer") .find('input[type=text]').focus(); }); Issues with jQuery: I have comments that belong to each .streamItem. My previous solution was to use ListView control as follows: <ItemTemplate> <asp:Panel ID="StreamItem" CssClass="StreamItem" runat="server"> ... <!-- Insert another nested ListView control here to load the comments for the parent stream. --> So as you can see, this is not a solution since I started using jQuery Templates and I am fetching the data using the following jQuery $.ajax method: $.ajax({ type: 'POST', url: 'Services.asmx/GetStream', data: "{}", contentType: 'application/json', success: function (Stream) { $.get('Templates/Stream.html', function (template) { $.tmpl(template, Stream.d).appendTo("#Stream"); }); } }); How can I resolve this without using the old ListView solution but by using jQuery Templates to load the comments whenever I am getting data for a specific stream? I am using a simple WebMethod to return my data as follows: [WebMethod] public List<Stream> GetStream() { List<Stream> Streams = Stream.GetRange(X, X, HttpContext.Current.User.Identity.Name); return Streams; } I am looking for a way to handle the .toggleInput click event. I need check if .Comments (a main container for the (to be comments container <div>)) has children (or more than one .commentItem). If so, then I need to show that .inputContainer and hide all the other .inputContainer divs with .Comments size() == 0 if they're visible. Please see the image below: Default.aspx (Partial CSS) div.streamItem div.clientView { float : left; width : 542px; } div.streamItem div.clientView p { margin : 5px 0 0 0; font-size : 10pt; } div.streamItem div.clientView div.inputContainer { display : none; /* Doesn't hide .inputContainer */ padding : 2px; background-color : #f1f1f1; } Issues with CSS: On page load, display: none; has no effect. That's it! If you're reading this I'd like to thank you for your time and thoughts! :)

• SharePoint 2010 – SQL Server has an unsupported version 10.0.2531.0

  - by Jeff Widmer

  I am trying to perform a database attach upgrade to SharePoint Foundation 2010. At this point I am trying to attach the content database to a Web application by using Windows Powershell: Mount-SPContentDatabase -Name <DatabaseName> -DatabaseServer <ServerName> -WebApplication <URL> [-Updateuserexperience] I am following the directions from this TechNet article: Attach databases and upgrade to SharePoint Foundation 2010.  When I go to mount the content database I am receiving this error: Mount-SPContentDatabase : Could not connect to [DATABASE_SERVER] using integrated security: SQL server at [DATABASE_SERVER] has an unsupported version 10.0.2531.0. Please refer to “http://go.microsoft.com/fwlink/?LinkId=165761” for information on the minimum required SQL Server versions and how to download them. At first this did not make sense because the default SharePoint Foundation 2010 website was running just fine.  But then I realized that the default SharePoint Foundation site runs off of SQL Server Express and that I had just installed SQL Server Web Edition (since the database is greater than 4GB) and restored the database to this version of SQL Server. Checking the documentation link above I see that SharePoint Server 2010 requires a 64-bit edition of SQL Server with the minimum required SQL Server versions as follows: SQL Server 2008 Express Edition Service Pack 1, version number 10.0.2531 SQL Server 2005 Service Pack 3 cumulative update package 3, version number 9.00.4220.00 SQL Server 2008 Service Pack 1 cumulative update package 2, version number 10.00.2714.00 The version of SQL Server 2008 Web Edition with Service Pack 1 (the version I installed on this machine) is 10.0.2531.0. SELECT @@VERSION: Microsoft SQL Server 2008 (SP1) - 10.0.2531.0 (X64)   Mar 29 2009 10:11:52   Copyright (c) 1988-2008 Microsoft Corporation  Web Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (VM) But I had to read the article several times since the minimum version number for SQL Server Express is 10.0.2531.0.  At first I thought I was good with the version of SQL Server 2008 Web that I had installed, also 10.0.2531.0.  But then I read further to see that there is a cumulative update (hotfix) for SQL Server 2008 SP1 (NOT the Express edition) that is required for SharePoint 2010 and will bump the version number to 10.0.2714.00. So the solution was to install the Cumulative update package 2 for SQL Server 2008 Service Pack 1 on my SQL Server 2008 Web Edition to allow SharePoint 2010 to work with SQL Server 2008 (other than the SQL Server 2008 Express version). SELECT @@VERSION (After installing Cumulative update package 2): Microsoft SQL Server 2008 (SP1) - 10.0.2714.0 (X64)   May 14 2009 16:08:52   Copyright (c) 1988-2008 Microsoft Corporation  Web Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (VM)

• phablet-flash aborting while installing Ubuntu Touch on Nexus 4

  - by Till B

  I have a Nexus 4 with Android 4.3 installed and I want to flash it to Ubuntu Touch. My system is Ubuntu 12.04, running inside a virtual machine on Mac OS 10.5.8. To use the VM, I opened an NAT bridge and forwarded port 5037 for adb, I can see the Nexus with adb and e.g. use the adb shell into it. USB ports are also forwarded to the VM. I follow these instructions to the letter. My bootloader is unlocked, just as it was described in the instructions. Now I encounter different issues, when executing sudo phablet-flash ubuntu-system --no-backup. On the first run, it got stuck in this state: INFO:phablet-flash:Decompressing partitions/recovery.img from /home/till/Downloads/phablet-flash/imageupdates/pool/device-5ba3031cb0d6fc624848266edba781e3e821b6e1e8dd21105725f0ab26077d0a.tar.xz INFO:phablet-flash:Restarting device... wait INFO:phablet-flash:Restarting device... wait complete INFO:phablet-flash:Booting /tmp/tmpMSN8bm/partitions/recovery.img < waiting for device > downloading 'boot.img'...

OKAY [ 0.005s] finished. total time: 1.779s INFO:phablet-flash:Waiting for recovery image to boot The following happened: around the line "INFO:phablet-flash: Restarting...", it rebooted into the bootloader. The bootloader shows only for two seconds, then the screen goes off and the phone stays off. But I do notice, that the screen is not off - it is just black, but the background light is on. If I wait long enough, phablet-flash aborts with ERROR:phablet-flash:Wait for recovery expired On the second try, I wanted to manually start the bootloader and choose "Recovery mode". Pressing "volume down+power" at first did nothing. Releasing the buttons and then pressing them again brought me into the bootloder. After choosing "Recovery mode", phablet-flash continued and after a while aborted with the following output: INFO:phablet-flash:Wait for recovery image to boot complete INFO:phablet-flash:Clearing /data and /cache INFO:phablet-flash:Pushing /home/till/Downloads/phablet-flash/imageupdates/pool/ubuntu-2b5345658b58e55207c4a4e7b6b3d8cd4f3d9a3187d2448fc9020c884234bac0.tar.xz to /cache/recovery/ failed to copy '/home/till/Downloads/phablet-flash/imageupdates/pool/ubuntu-2b5345658b58e55207c4a4e7b6b3d8cd4f3d9a3187d2448fc9020c884234bac0.tar.xz' to '/cache/recovery/': Permission denied ERROR:phablet-flash:Command 'adb push /home/till/Downloads/phablet-flash/imageupdates/pool/ubuntu-2b5345658b58e55207c4a4e7b6b3d8cd4f3d9a3187d2448fc9020c884234bac0.tar.xz /cache/recovery/' returned non-zero exit status 1 Removing directory /tmp/tmpDnbz6N Removing directory /tmp/tmpth4L6w What can I do to properly flash my phone with Ubuntu Touch?

• Cost justification for buying a 32GB superfast Alienware M18x with a price tag of around £5K ($10K)

  - by tonyrogerson

  When considering buying a laptop that’s going to cost me around £5,000 I really need to justify the purchase from a business perspective; my Lenovo W700 has served me very well for the last 2 years, it’s an extremely good machine and as solid as a rock (and as heavy), alas though it is limited to the 8GB. As SQL Server 2012 approaches and with my interest in working in the Business Intelligence space over the next year or two it is clear I need a powerful machine that I can run a full infrastructure though virtualised. My requirements For High Availability / Disaster Recovery research and demonstration Machine for a domain controller Four machines in a shared disk cluster (SQL Server Clustering active – active etc.) Five  machines in a file share cluster (SQL Server Availability Groups) For Business Intelligence research and demonstration Not entirely sure how many machine I want to run here, but it would be to cover the entire BI stack in an enterprise setting, sharepoint, sql server etc. For Big Data Research I have a fondness for the NoSQL approach to scalability and dealing with large volumes so I need a number of machines to research VoltDB, Hadoop etc. As you can see the requirements for a SQL Server consultant to service their clients well is considerable; will 8GB suffice, alas no, it will no longer do. I’m a very strong believer that in order to do your job well you must expense it, short cuts only cost you time, waiting 5 minutes instead of an hour for something to run not only saves me time but my clients time, I can do things quicker and more importantly I can demonstrate concepts. My W700 with the 8GB of RAM and SSD’s cost me around £3.5K two years ago, to be honest I’ve not got the full use I wanted out of it but the machine has had the power when I’ve needed it, it’s served me and my clients well. Alienware now do a model (the M18x) with 32GB of RAM; yes 32GB in a laptop! Dual drives so I can whack a couple of really good SSD’s in there, a quad core with hyper threading i7 and a decent speed. I can reduce the cost of the memory by getting it from Crucial, so instead of £1.5K for 32GB it will be around £900, I can also cost save on the SSD as well. The beauty about the M18x is that it is USB3.0, SATA 3 and also really importantly has eSATA, running VM’s will never be easier, I can have a removeable SSD with my VM’s on it and can plug it into my home machine or laptop – an ideal world! The initial outlay of £5K is peanuts compared to the benefits I’ll give my clients, I will be able to present real enterprise concepts, I’ll also be able to give training on those real enterprise concepts and with real, albeit virtualised machines.

• Windows Azure Use Case: Infrastructure Limits

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Physical hardware components take up room, use electricity, create heat and therefore need cooling, and require wiring and special storage units. all of these requirements cost money to rent at a data-center or to build out at a local facility. In some cases, this can be a catalyst for evaluating options to remove this infrastructure requirement entirely by moving to a distributed computing environment. Implementation: There are three main options for moving to a distributed computing environment. Infrastructure as a Service (IaaS) The first option is simply to virtualize the current hardware and move the VM’s to a provider. You can do this with Microsoft’s Hyper-V product or other software, build the systems and host them locally on fewer physical machines. This is a good option for canned-applications (where you have to type setup.exe) but not as useful for custom applications, as you still have to license and patch those servers, and there are hard limits on the VM sizes. Software as a Service (SaaS) If there is already software available that does what you need, it may make sense to simply purchase not only the software license but the use of it on the vendor’s servers. Microsoft’s Exchange Online is an example of simply using an offering from a vendor on their servers. If you do not need a great deal of customization, have no interest in owning or extending the source code, and need to implement a solution quickly, this is a good choice. Platform as a Service (PaaS) If you do need to write software for your environment, your next choice is a Platform as a Service such as Windows Azure. In this case you no longer manager physical or even virtual servers. You start at the code and data level of control and responsibility, and your focus is more on the design and maintenance of the application itself. In this case you own the source code and can extend or change it as you see fit. An interesting side-benefit to using Windows Azure as a PaaS is that the Application Fabric component allows a hybrid approach, which gives you a basis to allow on-premise applications to leverage distributed computing paradigms. No one solution fits every situation. It’s common to see organizations pick a mixture of on-premise, IaaS, SaaS and PaaS components. In fact, that’s a great advantage to this form of computing - choice.

• Announcing: Improvements to the Windows Azure Portal

  - by ScottGu

  Earlier today we released a number of enhancements to the new Windows Azure Management Portal.  These new capabilities include: Service Bus Management and Monitoring Support for Managing Co-administrators Import/Export support for SQL Databases Virtual Machine Experience Enhancements Improved Cloud Service Status Notifications Media Services Monitoring Support Storage Container Creation and Access Control Support All of these improvements are now live in production and available to start using immediately.  Below are more details on them: Service Bus Management and Monitoring The new Windows Azure Management Portal now supports Service Bus management and monitoring. Service Bus provides rich messaging infrastructure that can sit between applications (or between cloud and on-premise environments) and allow them to communicate in a loosely coupled way for improved scale and resiliency. With the new Service Bus experience, you can now create and manage Service Bus Namespaces, Queues, Topics, Relays and Subscriptions. You can also get rich monitoring for Service Bus Queues, Topics and Subscriptions. To create a Service Bus namespace, you can now select the “Service Bus” tab in the Windows Azure portal and then simply select the CREATE command: Doing so will bring up a new “Create a Namespace” dialog that allows you to name and create a new Service Bus Namespace: Once created, you can obtain security credentials associated with the Namespace via the ACCESS KEY command. This gives you the ability to obtain the connection string associated with the service namespace. You can copy and paste these values into any application that requires these credentials: It is also now easy to create Service Bus Queues and Topics via the NEW experience in the portal drawer.  Simply click the NEW command and navigate to the “App Services” category to create a new Service Bus entity: Once you provision a new Queue or Topic it can be managed in the portal.  Clicking on a namespace will display all queues and topics within it: Clicking on an item in the list will allow you to drill down into a dashboard view that allows you to monitor the activity and traffic within it, as well as perform operations on it. For example, below is a view of an “orders” queue – note how we now surface both the incoming and outgoing message flow rate, as well as the total queue length and queue size: To monitor pub/sub subscriptions you can use the ADD METRICS command within a topic and select a specific subscription to monitor. Support for Managing Co-Administrators You can now add co-administrators for your Windows Azure subscription using the new Windows Azure Portal. This allows you to share management of your Windows Azure services with other users. Subscription co-administrators share the same administrative rights and permissions that service administrator have - except a co-administrator cannot change or view billing details about the account, nor remove the service administrator from a subscription. In the SETTINGS section, click on the ADMINISTRATORS tab, and select the ADD button to add a co-administrator to your subscription: To add a co-administrator, you specify the email address for a Microsoft account (formerly Windows Live ID) or an organizational account, and choose the subscription you want to add them to: You can later update the subscriptions that the co-administrator has access to by clicking on the EDIT button, and then select or deselect the subscriptions to which they belong. Import/Export Support for SQL Databases The Windows Azure administration portal now supports importing and exporting SQL Databases to/from Blob Storage.  Databases can be imported/exported to blob storage using the same BACPAC file format that is supported with SQL Server 2012.  Among other benefits, this makes it easy to copy and migrate databases between on-premise and cloud environments. SQL Databases now have an EXPORT command in the bottom drawer that when pressed will prompt you to save your database to a Windows Azure storage container: The UI allows you to choose an existing storage account or create a new one, as well as the name of the BACPAC file to persist in blob storage: You can also now import and create a new SQL Database by using the NEW command.  This will prompt you to select the storage container and file to import the database from: The Windows Azure Portal enables you to monitor the progress of import and export operations. If you choose to log out of the portal, you can come back later and check on the status of all of the operations in the new history tab of the SQL Database server – this shows your entire import and export history and the status (success/fail) of each: Enhancements to the Virtual Machine Experience One of the common pain-points we have heard from customers using the preview of our new Virtual Machine support has been the inability to delete the associated VHDs when a VM instance (or VM drive) gets deleted. Prior to today’s release the VHDs would continue to be in your storage account and accumulate storage charges. You can now navigate to the Disks tab within the Virtual Machine extension, select a VM disk to delete, and click the DELETE DISK command: When you click the DELETE DISK button you have the option to delete the disk + associated .VHD file (completely clearing it from storage).  Alternatively you can delete the disk but still retain a .VHD copy of it in storage. Improved Cloud Service Status Notifications The Windows Azure portal now exposes more information of the health status of role instances.  If any of the instances are in a non-running state, the status at the top of the dashboard will summarize the status (and update automatically as the role health changes): Clicking the instance hyperlink within this status summary view will navigate you to a detailed role instance view, and allow you to get more detailed health status of each of the instances.  The portal has been updated to provide more specific status information within this detailed view – giving you better visibility into the health of your app: Monitoring Support for Media Services Windows Azure Media Services allows you to create media processing jobs (for example: encoding media files) in your Windows Azure Media Services account. In the Windows Azure Portal, you can now monitor the number of encoding jobs that are queued up for processing as well as active, failed and queued tasks for encoding jobs. On your media services account dashboard, you can visualize the monitoring data for last 6 hours, 24 hours or 7 days. Storage Container Creation and Access Control Support You can now create Windows Azure Storage storage containers from within the Windows Azure Portal.  After selecting a storage account, you can navigate to the CONTAINERS tab and click the ADD CONTAINER command: This will display a dialog that lets you name the new container and control access to it: You can also update the access setting as well as container metadata of existing containers by selecting one and then using the new EDIT CONTAINER command: This will then bring up the edit container dialog that allows you to change and save its settings: In addition to creating and editing containers, you can click on them within the portal to drill-in and view blobs within them.  Summary The above features are all now live in production and available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using them today.  Visit the Windows Azure Developer Center to learn more about how to build apps with it. We’ll have even more new features and enhancements coming later this month – including support for the recent Windows Server 2012 and .NET 4.5 releases (we will enable new web and worker role images with Windows Server 2012 and .NET 4.5, and support .NET 4.5 with Websites).  Keep an eye out on my blog for details as these new features become available. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• PASS 13 Dispatches: moving to the cloud

  - by Tony Davis

  PASS Summit 13, Day 1 keynote by Quentin Clarke and we're hearing about “redefiniing mission critical in the cloud”. With a move to the Windows Azure cloud comes the promise of capacity on demand, automatic HA, backups, patching and so on, as well as passing responsibility to MS for managing hardware, upgrades and so on. However, for many databases and applications the best route to the cloud is not necessarily obvious. For most, the path of least resistance is IaaS – SQL Server in a Azure VM. It removes the hardware burden but you still have to manage your databases and implementing HA for SQL Server is your responsibility. Also, scaling up comes at quite a cost – the biggest VM (8 CPU cores, 56 GB RAM, 16 1TB drives with 500 IOPS each) weighs in at over over $4500 per month. With PaaS, in the form of Windows SQL Database, you get a “3-copies replica set” so HA comes out-of the box, and removes the majority of the administration burden, but you are moving your database into a very different environment. For a start, it's a shared environment, with other customers using the same compute nodes in the cluster, and potentially even sharing the same database (multi-tenancy). Unless you pay for SQL DB Premium edition, the resources available for your workload will depends on how nicely others “play” in the shared environment. You'll potentially need to do a lot of tuning, and application rewriting to avoid throttling issues, optimising application-database communication to deal with increased latency between the two, and so on. You'll need aggressive application caching. You'll also need retry logic and to deal with (expected) node failure and the need to reconnect. In Tuesday's PASS Summit pre-con from the SQLCAT team, they spent a lot of time covering some of the telemetric techniques (collect into Azure storage the necessary monitoring data) to perform capacity planning, work out the hotspots and bottlenecks in your cloud applications. Tools like WAD (Windows Azure Diagnostics), performance counters SQL Database DMVs, and others, will be essential. Of course, to truly exploit the vast horizontal scaling that is available from the existence of thousands of compute nodes, you'll also need to need to consider how to “shard” your data so Azure can move it between nodes at will. Finding the right path to the Cloud isn't easy, but it's coming. I spoke to people one year ago who saw no real benefit in trying to move their infrastructure and databases to the cloud, but now at their company, it's the conversation that won't go away. Tony.

• debootstrap or virt-install Ubuntu Server Maverick fails

  - by poelinca

  Oki so running any kind of variation of debootsrap i get the following error I: Extracting zlib1g... W: Failure trying to run: chroot /lxc/iso/dodo mount -t proc proc /proc debootstrap.log : mount: permission denied if i manualy chroot into the directory then i get promted with: id: cannot find name for group ID 0 I have no name!@...# i tryed addgroup but it's not installed , apt-get/aptitude : command not found , so i can't do anything with it . I've tryed ubuntu-vm-builder but since it's calling debootstrap i get the same error . Played with it for a few days and then i stoped and gaved virt-install a try , everithing works till i get to the console to finish the install witch shows only : Escape character is ^] and nothing more , no matter what i type . So basicly what i'm trying to do is build a usable chroot system so i can use it with lxc or libvirt . What are my options to get containers/virtualisation up and running ? I've read somewhere that i can use openvz templates with lxc or libvirt ? but how ? Let me know if you need aditional info ( p.s. doing all this on a dedicated server so i can't access it by hand , only ssh , plus on my local pc running ubuntu desktop maverick everithing works ) . EDIT Getting closer , i managed to understand how to use an openvz template with lxc , now the problem comes with the network bridge lxc-start: invalid interface name: br0 # Use same bridge device used in your controlling host setup lxc-start: failed to process 'lxc.network.link = br0 # Use same bridge device used in your controlling host setup ' lxc-start: failed to read configuration file i followed the exact steps to create a bridge and lxc conf looks like: lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 # Use same bridge device used in your controlling host setup lxc.network.hwaddr = {a1:b2:c3:d4:e5:f6} # As appropiate (line only needed if you wish to dhcp later) lxc.network.ipv4 = {10.0.0.100} # (Use 0.0.0.0 if you wish to dhcp later) lxc.network.name = eth0 # could likely be whatever you want Since it's not working i know smth is wrong so could somebody guyde me ? EDIT , looks like the base install was using an custom kernel ( bzImage-2.6.34.6-xxxx-grs-ipv6-65 ) for witch you i didn't found the headers , i did a update-grub after i installed a new kernel , edited menu.lst and no it's using 2.6.35-23-server and now debootstrap is working just fine same as ubuntu-vm-builder .

• small IIS web farm-create an Active Directory domain or no?

  - by brian b

  We have a smallish web farm of < 5 Windows 2008 servers. Some do data, most do IIS hosting. Is it a good/bad idea to set up a domain controller and put all in the same "production" domain? We want to avoid a world where we have to sync multiple admin passwords between the boxes (or share admin credentials among the team). Presumably, the DC would be just another VM, so hardware cost doesn't enter into the discussion.
