• Node remains in commissioning status

  - by Vinitha

  I have been trying to set up ubuntu cloud 12.04. I'm kind of new to MAAS and ubuntu. Here is what I followed. Have installed MAAS server using the steps provided in https://wiki.ubuntu.com/ServerTeam/MAAS For the node, I installed the Ubuntu 12.04 Server Image on a USB Stick. Then restarted the node and opted to enlist the node via boot media, with PXE. once the process was done, the node was powered off as expected. I manually powered on the node, as my node is not PXE enabled. Result - No node was visible on MAAS UI Since step 2 didn't work, I added the node via maas-cli. command. After the execution of this command I got the node reflected on to my MAAS UI. But the status continues to be in "Commissioning" for a long time. Then I executed "maas-cli maas nodes check-commissioning " and i got "Unrecognised signature: POST check_commissioning". I'm not sure where is the error. Could some one please help me solve this issue. I checked the following log file but found no error related to commissioning (pserv.log / maas.log / celery.log/celery-region.log). I found this entry in my auth.log "Nov 16 18:20:34 ubuntuCloud sshd[4222]: Did not receive identification string from xxx.xx.xx.x" not sure if it indicates anything as the ip that is mentioned is not of the node nor of the MAAS server. I also verified the time on the server and node using date cmd - (at one instance the times are : Server: Fri Nov 16 18:15:51 IST 2012 and Node Fri Nov 16 18:15:43 IST 2012). Not sure if 'date' the right cmd to set the time. I have also check maas_local_settings.py for the MAAS url. I'm not sure what are the logs that need to be verified. Is there any log that can be checked on the Node. Thanks Vinitha

• Visual Studio LightSwitch: Yes, these are the droids you&rsquo;re looking for

  - by Jim Duffy

  With all the news and focus on the new features coming in Silverlight 5 I thought I’d take a few minutes to remind folks about the work that Microsoft has done on LightSwitch since the applications created by LightSwitch are Silverlight applications. LightSwitch makes it easier for non-coders to build business applications and easier for coders to maintain them. For those not familiar with LightSwitch, it is a new tool that provides a easier and quicker way for coder and non-coder types alike to create line-of-business applications for the desktop, the web, and the cloud. The target audience for this tool are those power-user types who create Access applications for their organization. While those Access applications fill an immediate need, they typically aren’t very scalable, extendable and/or maintainable by the development staff of the organization. LightSwitch creates applications based on technologies built into Visual Studio thus making it easier for corporate developers to extend and maintain them. LightSwitch is currently in beta but it will ultimately become a new addition to the Visual Studio line of products. Go ahead and download the beta to get a better idea of what the product can do for your organization. The LightSwitch Developer Center contains links to download the beta links to instructional videos links to tutorials links to the LightSwitch Training Kit Another quality resource for LightSwitch information is the Visual Studio LightSwitch Team Blog. My good friend Beth Massi is on the LightSwitch team and has additional valuable content on her blog. Have a day.

• Page debugging got easier in UCM 11g

  - by kyle.hatlestad

  UCM is famous for it's extra parameters you can add to the URL to do different things. You can add &IsJava=1 to get all of the local data and result set information that comes back from the idc_service. You can add &IsSoap=1 and get back a SOAP message with that information. Or &IsJson=1 will send it in JSON format. There are ones that change the display like &coreContentOnly=1 which will hide the footer and navigation on the page. In 10g, you could add &ScriptDebugTrace=1 and it would display the list of resources that were called through includes or eval functions at the bottom of the page. And it would list them in nested order so you could see the order in which they were called and which components overrode each other. But in 11g, that parameter flag no longer works. Instead, you get a much more powerful one called &IsPageDebug=1. When you add that to a page, you get a small gray tab at the bottom right-hand part of the browser window. When you click it, it will expand and let you choose several pieces of information to display. You can select 'idocscript trace' and display the nested includes you used to get with ScriptDebugTrace. You can select 'initial binder' and see the local data and result sets coming back from the service, just as you would with IsJava. But in this display, it formats the results in easy to read tables (instead of raw HDA format). Then you can get the final binder which would contain all of the local data and result sets after executing all of the includes for the display of the page (and not just from the Service call). And then a 'javascript log' for reporting on the javascript functions and times being executed on the page. Together, these new data displays make page debugging much easier in 11g. *Note: This post also applies to Universal Records Management (URM).

• NTFS and NTFS-3G

  - by MestreLion

  I have a netbook with Ubuntu Netbook 10.04 and a desktop with Mint 10 (~ Ubuntu Desktop 10.10) Both of them have read/write NTFS partitions mounted via /etc/fstab. And it works fine. Ive read on net, google, forums, and several posts here, that NTFS-3G is the driver that allows you to have full access to an NTFS partition, that it is new, great, powerful, yada-yada. But... my entries use plain ntfs, no mention of -3g, and they still work perfectly as read and write. Am I already using ntfs-3g? Does 10.04 onwards use it "under the hood"? How can i check that in my system? Should my /etc/fstab entries should use "ntfs-3g" as the fs? Why some posts refer to mount ntfs, while others say mount ntfs-3g ? Im really confused about where should I use fs-type names (ntfs) or driver names (ntfs-3g?). Or is it irrelevant now, and ntfs is always an "alias" or something for ntfs-3g nowadays? Ive read some posts her, from Oct-10 and Nov-10 e that "announce" that ntfs-3g "finally arrived"... thats way post-Lucid 10.04. Could someone please undo this mess in my head, and explain the relation between ntfs and ntfs-3g, what is the current status (10.04 and 10.10), where should i use each, etc (regarding mount, fstab, etc)? Sorry for the long, confusing, redudant text... im really getting sleepy

• Why is this PHP loop rendering every row twice?

  - by Christopher

  I'm working on a real frankensite here not of my own design. There's a rudimentary CMS and one of the pages shows customer records from a MySQL DB. For some reason, it has no probs picking up the data from the DB - there's no duplicate records - but it renders each row twice. The page PHP is viewable at http://christopher.pastebin.com/DQkjjG3s (attempted to include in this post but it was horribly mangled, think it's important to have it all in context). I'm not the world's best PHP expert but I think I can see an error in a for loop when there is one... But everything looks ok to me. You'll notice that the customer name is clickable; clicking takes you to another page where you can view their full info as held in the DB - and for both rows, the customer ID is identical, and manually checking the DB shows there's no duplicate entries. The code is definitely rendering each row twice, but for what reason I have no idea. All pointers / advice appreciated.

• Introducing Kiddo: A Ruby DSL for building simple WPF and Silverlight applications

  - by fdumlao

  Read the original article here... As a long time Ruby lover and deep rooted .NET supporter, I was probably more psyched than anyone I knew when IronRuby 1.0 was finally released. I immediately grabbed and started building some apps with it to see where the boundaries were going to lie between IronRuby and ruby.exe, and so far I've been pleasantly surprised by how many things just work as I'd expect. I then started to try out some of my favorite libs that I was sure would not work with IronRuby, and I wasn't surprised at all when _why's amazing Shoes library didn't work. Being somewhat familiar with Shoes (it's a great DSL for building simple UIs in Ruby) I felt it wouldn't be that difficult to port it over and as it turned out, someone else had already started the work. As cool as this was, I was never quite satisfied with good 'ol shoes. While it was quite complete, it lacked simple extensibility points, and although easy, it wasn't quite "kid friendly". At the same time on the .NET side of the fence, IronRuby could easily compile XAML to create WPF and Silverlight UIs, but trying to do it declaratively in plain Ruby was no fun at all. And so, the Shoes-inspired, WPF/Silverlight GUI DSL was born. (and it lives here: http://bitbucket.org/fdumlao/kiddo/src) Introducing Kiddo Tell you what. Let's start with a quick code example first. We'll build a useful app that we can use to quickly reverse strings whenever we need it. Read the complete article here...

• How do I get KLIPS or NETKEY on 11.10 server?

  - by Incognito

  I'm attempting to run OpenSWAN on my Ubuntu11.10 server. All I've done so far is install openswan from the package manager and attempt to set up conf files. However, IPSec support seems to be broken, thus OpenSWAN can't do it's thing.

• Examining ASP.NET's Membership, Roles, and Profile - Part 18

  Membership, in a nutshell, is a framework build into the .NET Framework that supports creating, authenticating, deleting, and modifying user account information. Each user account has a set of core properties: username, password, email, a security question and answer, whether or not the account has been approved, whether or not the user is locked out of the system, and so on. These user-specific properties are certainly helpful, but they're hardly exhaustive - it's not uncommon for an application to need to track additional user-specific properties. For example, an online messageboard site might want to also also associate a signature, homepage URL, and IM address with each user account. There are two ways to associate additional information with user accounts when using the Membership model. The first - which affords the greatest flexibility, but requires the most upfront effort - is to create a custom data store for this information. If you are using the SqlMembershipProvider, this would mean creating an additional database table that had as a primary key the UserId value from the aspnet_Users table and columns for each of the additional user properties. The second option is to use the Profile system, which allows additional user-specific properties to be defined in a configuration file. (See Part 6 for an in-depth look at the Profile system.) This article explores how to store additional user information in a separate database table. We'll see how to allow a signed in user to update these additional user-specific properties and how to create a page to display information about a selected user. What's more, we'll look at using ASP.NET Routing to display user information using an SEO-friendly, human-readable URL like www.yoursite.com/Users/username. Read on to learn more! Read More >

• How do I elevate privileges when running appcmd from a nant task?

  - by Rune

  We are using a Windows 7 box as build server. As part of our continuous integration process I would like to stop and start an IIS 7 website. I have tried doing this from the command line using appcmd: appcmd start site "my website" However, this only works if I start the console window by choosing "Run as Administrator", so it won't work out-of-the-box from NAnt etc. How do I script appcmd to be run with elevated privileges (or am I going about this in the wrong way)? Thank you.

• Icinga error "Icinga Startup Delay does not exist" although it does

  - by aaron

  I just installed icinga to monitor my server following this guide: http://docs.icinga.org/0.8.1/en/wb_quickstart-idoutils.html Everything built and installed correctly, but icinga is reporting a critical error with the reason: "The command defined for service Icinga Startup Delay does not exist" However, I can see that ${ICINGA_BASE}/etc/objects/localhost.cfg contains: define service{ use local-service ; Name of service template to use host_name localhost service_description Icinga Startup Delay check_command check_icinga_startup_delay notifications_enabled 0 } and ${ICINGA_BASE}/etc/objects/commands.cfg contains: define command { command_name check_icinga_startup_delay command_line $USER1$/check_dummy 0 "Icinga started with $$(($EVENTSTARTTIME$-$PROCESSSTARTTIME$)) seconds delay | delay=$$(($EVENTSTARTTIME$-$PROCESSSTARTTIME$))" } both of these files had not been modified since the whole make/install process. I am running on Ubuntu 10.04, most recent build of icinga-core, and apache2 2.2.14 What must I do to tell Icinga that the command exists? Or is the problem that check_dummy does not exist? Where or how would I define that?

• ODI 11g – Scripting Repository Creation

  - by David Allan

  Here’s a quick post on how to create both master and work repositories in one simple dialog, its using the groovy capabilities in ODI 11g and the groovy swing builder components. So if you want more/less take the groovy script and change, its easy stuff. The groovy script odi_create_repos.groovy is here, just open it in ODI before connecting and you will be able to create both master and work repositories with ease – or check the groovy out and script your own automation – you can construct the master, work and runtime repositories, so if you are embedding ODI as your DI engine this may be very useful. When you click ‘Create Repository’ you will see the following in the log as the master repository starts to be created; ====================================================== Repository Creation Started.... ====================================================== Master Repository Creation Started.... Then the completion message followed by the work repository creation and final completion message. Master Repository Creation Completed. Work Repository Creation Started. Work Repository Creation Completed. ====================================================== Repository Creation Completed Successfully ====================================================== Script exited. If any error is hit, the script just exits and prints any error to the log. For example if I enter no passwords, I will get this error; ====================================================== Repository Creation Started.... ====================================================== Master Repository Creation Started.... ====================================================== Repository Creation Complete in Error ====================================================== oracle.odi.setup.RepositorySetupException: oracle.odi.core.security.PasswordPolicyNotMatchedException: ODI-10189: Password policy MinPasswordLength is not matched. ====================================================== Script exited. This is another example of using the ODI 11g SDK showing how to automate the construction of your data integration environment. The main interfaces and classes used here are IMasterRepositorySetup / MasterRepositorySetupImpl and IWorkRepositorySetup / WorkRepositorySetupImpl.

• Is copy paste programming bad ?

  - by ring bearer

  With plain google as well as google code search tools it is easy to find how to program using some resource or solve certain problems ( such as a Java class, or a ftp block in perl etc) and so developers are so tempted to just purely copy paste the code (in a way re-use) - is this an incompetency? I have done this myself though I think I am a better programmer than many others I have seen. Who has the time to RTFM? In this age of information abundance, I do not think that copy paste programming is bad. Isn't that what sites like stackoverflow do anyway? People ask - ok here is my problem - how to solve it? now someone will post complete code and the person who asked the question would simply copy paste the most voted answer. No matter how small the problem is. I am working with a bunch of young coders who heavily rely on internet to get their job done. I see convenience (for example, you may be quite good with algorithms and such but you may not know how to use a BufferedReader in Java - would you read complete Javadoc for BufferedReader or look up some example of using it somewhere??) in copy pasting and modifying code to get the job done. What are the real dangers of copy paste coding that can impact their competency?

• Can you authenticate into SSAS with AD LDS (ADAM) accounts?

  - by Jaxidian

  I'm very new to AD LDS and experienced but not qualified with SSAS, so my apologies for my ignorances with these. We have a couple implementations where we expose SSAS via an HTTPS proxy (msmdpump.dll) and currently we have a temporary domain setup handling this (where our end-users have a second account+creds to manage because of this = non-ideal). I want to move us towards a more permanent solution which I'm thinking of moving all authentication to AD LDS for our web apps, SSAS, and others. However, SSAS is where I'm concerned about this. I know SSAS requires Windows Authentication and to play nicely, and that this ultimately means Active Directory will be involved. Is there a way to get this done with AD LDS instead of having to use a full AD DS implementation? If so, how? (Note: My question over at StackOverflow had a suggestion that I post this question here on ServerFault instead. My apologies if I'm not asking in the right forum.)

• Issue 15: Introducing David Callaghan

  - by rituchhibber

      DAVID'S VIEW INTRODUCING DAVID CALLAGHAN David Callaghan Senior Vice President, Oracle EMEA Alliances and Channels David Callaghan is the Senior Vice President, Alliances & Channels, for Oracle EMEA. He is responsible for all elements of the Oracle Partner Network across the region and leads Oracle as it continues to deliver customer success through the alignment of Oracle's applications and hardware engineered to work together. As I reflect on our last quarter, I thank all our partners for your continued commitment and expertise in embracing the unique opportunity we have before us. The ability to engage with hardware, applications and technology is a real differentiator. We have been able to engage with deep specialization in individual products for some time, which has brought tremendous benefits. But now we can strengthen this further with the broad stack specialization that Oracle on Oracle brings. Now is the time to make that count. While customers are finishing spending this year's budget and planning their spend for the next calendar year, it is now that we need to build the quality opportunities and pipeline for the rest of the year. We have OpenWorld just around the corner with its compelling new product announcements and environment to engage customers at all levels. Make sure you use this event, and every opportunity it brings. In the next quarter you can expect to see targeted 'value creation' campaigns driven by Oracle, and I encourage you to exploit these where they will have greatest impact. My team will be engaging closely with their Oracle sales colleagues to help them leverage the tremendous value you bring, and to develop their ability to work effectively and independently with you, our partners. My team and I are all relentlessly committed to achieving partner, and customer, satisfaction to demonstrate the value of the Passion for Partnering that we all share. With best regards David Back to the welcome page

• Twitter status id conundrum

  - by jamiet

  I have an interest, a slightly perverse one some might say, in using online services and trying to figure out what the underlying (logical) data model is and in this day and age Twitter is one that lends itself very well to scrutiny. Consider this recent tweet of mine: The URL that enables you to see that tweet is http://twitter.com/jamiet/status/12154647354. We can interpret that URL to mean "a tweet by jamiet with an id of 12154647354" and hence we might further assume that the unique identifier for the tweet is {jamiet,12154647354}. However, its well-known that Twitter gives each status a unique ID regardless of who tweeted it so we might expect we could reach that tweet just by using a URL of http://twitter.com/status/12154647354 however (at the time of writing) that only redirects to Twitter's homepage. That seems strange to me especially given that we can use Twitter's API to access information about that tweet using only the id of the status. Witness http://api.twitter.com/1/statuses/show/12154647354.xml: [We can also access a JSON version of that information using http://api.twitter.com/1/statuses/show/12154647354.json] I'm puzzled as to why a tweet can't be accessed using on the main twitter website using the id alone. Anyone have any suggestions? @jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Book Review: Getting Started With Window 8 Apps By Ben Dewey

  - by Tim Murphy

  When O’Reilly gave me an opportunity to review this book I was excited.  It gave me a reason to finally put some time into this new platform and what developers will need to learn in order to be successful. This book by Ben Dewey is only 92 pages long, so if you were looking for an in-depth treatment of Windows 8 development you will need supplemental materials.  It is also due for an update from the perspective of recent changes made by Microsoft prior to the final release of the OS and tools.  This causes a few issues if you try to run the code samples because of namespace changes. I was encouraged by the fact that the author didn’t do the typical “hello world” app.  He uses a lot of pattern based development techniques and hits many of the main topics including: Application lifecycle Charms integration Tiles Sensors The lifecycle is critical for anyone who hasn’t done mobile development before.  Limited resources on these devices mean that the OS can suspend or kill your app altogether if it decides it needs to.  He covers tombstoning which is the key to Windows 8 and Windows Phone lifecycle management. He also dedicates a chapter to marketing and distributing the application you build.  From my experience with Windows Phone development this is crucial information.  You need to know how to test your application so that it is going to pass certification and present your app so that it is going to get noticed amongst thousands of other apps. The main things that I wish had been in the book explanations of more of the common controls and more complete explanation of patterns that were implemented. In the end this book is a good foundation getting exposure to the concepts that underlie this new version of the Windows platform and how it effects developers.  It isn’t a book that I would suggest for someone just getting into development with no understanding of pattern based development. del.icio.us Tags: Windows 8,O'Reilly,Ben Dewey,Book Review,Review

  Hello I thought I had solved this nightmare by re-entering the values in my SSP properties set up, however accessing the Search Settings page error has reared it ugly head again. Now all solutions point to this method listed here * http://www.routtlogics.com/blog/Lists/Posts/Post.aspx?ID=6 * http://social.technet.microsoft.com/Forums/en-US/sharepointadmin/thread/f00651cd-e452-45b9-b19e-90e89c3c3ad4 * http://blogs.technet.com/sushrao/archive/2009/03/26/microsoft-office-sharepoint-server-2007-moss-403-forbidden-error-when-clicked-on-search-settings-page.aspx The above workaround(s) basically states that granting the local group WSS_WPG read and write permission to the Task folder in the Windows directory would solve the problem, however whenever I try to change to the permission attribute of this folder I get an access denied message, even when logged in as a Domain administrator, Enterprise and even the SharePoint Farm administrator.

• How to enable "Sleep" for Windows 2012 server

  - by Ramesh

  I recently installed Windows Server 2012. This will serve as the dev-instance for our engineers and will be accessed in multiple time zones. I therefore plan to run this 24x7 but want to conserve energy by going to sleep mode when not in use & enable Wake-On-Magic-Packet. Based on the previous post it appears that there is no option to sleep Win Server 2012 with Hyper-V. Since I don't care much about virtualization now, I uninstalled Hyper-V. In addition to this, I have done the following 1) Ran powercfg -a. Don't find sleep. 2) Added [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot] "Start"=dword:00000003 to try gaining sleep - no luck! 3) Only see Shutdown and Restart in power options. Please help me sleep and save the planet :-) Thanks, Ramesh

• Formating Columns in Excel created by af:exportCollectionActionListener

  - by Duncan Mills

  The af:exportCollectionActionListener behavior in ADF Faces Rich client provides a very simple way of quickly dumping out the contents or selected rows in a table or treeTable to Excel. However, that simplicity comes at a price as it pretty much left up to Excel how to format the data. A common use case where you have a problem is that of ID columns which are often long numerics. You probably want to represent this data as a string, Excel however will probably have other ideas and render it as an exponent  - not what you intended. In earlier releases of the framework you could sort of work around this by taking advantage of a bug which would allow you to surround the outputText in question with invisible outputText components which provided formatting hints to Excel. Something like this: <af:column headertext="Some wide label">  <af:panelgrouplayout layout="horizontal">     <af:outputtext value="=TEXT(" visible="false">     <af:outputtext value="#{row.bigNumberValue}" rendered="true"/>    <af:outputtext value=",0)" visible="false">   </af:panelgrouplayout> </af:column> However, this bug was fixed and so it can no longer be used as a trick, the export now ignores invisible columns. So, if you really need control over the formatting there are several alternatives: First the more powerful ADF Desktop Integration (ADFdi) package which allows you to build fully transactional spreadsheets that "pull" the data and can update it. This gives you all the control that might need on formatting but it does need specific Excel Add-ins on the client to work. For more information about ADFdi have a look at this tutorial on OTN. Or you can of course look at BI Publisher or Apache POI if you're happy with output only spreadsheets

• Dichroic Glass in Blender

  - by KalAurum

  I am trying to use blender to simulate the Lycurgus Cup. The cup is an example of dichroic (two-color) glass, and appears green when a light source is on the outside of the cup, and appears red when a light source is inside the cup. Here is an image of when light is outside and it appears green: Here is an image of when light is inside and it appears red: I have created a glass cup in blender. I have made the glass a red color, and then used the colorbands under the Object-Material/Shading-Ramps tab to add green specular and diffuse color. However, this makes the glass appear the same mix of red and green whether I put the light source on the inside or outside the cup. An example can be seen here: According to the second post here, someone was able to to fake the effect of a dichroic glass in blender rather easily through the use of a magic procedural texture but they provide no clues on how to do this (in blender). Does anyone know how to achieve this effect in blender?

• aliasing "git" ssh login to "gitolite"

  - by Randal Schwartz

  I'm installing gitolite from CentOS packages for my client. The package creates a gitolite user, which will be visible explicitly during a "git clone" operations. The client wants to use "git" and not "gitolite", in case we change to something more fancy later. I'm not very familiar with CentOS, so I don't want to try to build the package myself from source. I'm wondering if there's a way to do one of the following: Trick sshd into treating "git" as "gitolite". Somehow "alias" a new git username to be the same in all ways as the existing gitolite username (perhaps through some complex combinations of useradd). Rename the "gitolite" username to "git" without upsetting later yum update operations Something else that I hadn't thought of I'd appreciate detailed instructions or pointers.

• Setting CATALINA_OPTS for tomcat6 on windows doesn’t work.

  - by Ben

  (I've copied this from Stack Overflow here, after someone suggested I post the question here) Hi, I'm trying to setup Tomcat6 to work with JMX on Windows Vista 64. To do that I need to pass the parameters below to Tomcat6. What I do in command prompt. (that doesn't work) set CATALINA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9898 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false" tomcat6.exe What I do that does work (but causes other problems) java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9898 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -jar bootstrap.jar It seems as if tomcat is just ignoring the environment variable CATALINA_OPTS. Am I doing something wrong? I've also tried to edit catalina.bat and define the variable CATALINA_OPTS there. No success. (tried adding the parameters to JAVA_OPTS too, no success either) Thanks in Advance!!

• How to get Facebook-Feeds in Trillian without connecting to Facebook-Chat?

  - by Protron

  I installed the trial of Trillian 5.0 Build 22 (I don't know if the version 4 Astra is any different). I successfully added my Facebook account so I can see my facebook news on Trillian and works great. The problem is that I don't want to use the Facebook-chat, and if I disconnect the Facebook-chat the rest of the facebook stuff (news, events, groups, request) also disappears. I tried by setting the Facebook status to Away; and I'm not sure if someone can chat with me if I choose that; but anyway I still have the contacts list full of people I don't want. EDIT: Maybe I wasn't clear enough about the Facebook part. And that might be why some people fell this is off-topic. But when I talk about Facebook in this question, I'm not referring to the Facebook site at any point. I'm mean the Facebook plugin of Trillian (and it's not an user plugin; it's a built-in plugin).

• How to write PowerShell code part 4 (using loop)

  - by ybbest

  In this post, I’d like to show you how to loop through the xml element. I will use the list data deletion script as an example. You can download the script here. 1. To perform the loop, I use foreach in powershell. Here is my xml looks like <?xml version="1.0" encoding="utf-8"?> <Site Url="http://workflowuat/npdmoc"> <Lists> <List Name="YBBEST Collaboration Areas" Type="Document Library"/> <List Name="YBBEST Project" /> <List Name="YBBEST Document"/> </Lists> </Site> 2. Here is the PowerShell to manipulate the xml. Note, you need to get to the $configurationXml.Site.Lists.List variable rather than $configurationXml.Site.Lists foreach ($list in $configurationXml.Site.Lists.List){ AppendLog "Clearing data for $($list.Name) at site $weburl" Yellow if($list.Type -eq "Document Library"){ deleteItemsFromDocumentLibrary -Url $weburl -ListName $list.Name }else{ deleteItemsFromList -Url $weburl -ListName $list.Name } AppendLog "Data in $($list.Name) at $weburl is cleared" Green } How to write PowerShell code part 1 How to write PowerShell code part 2 How to write PowerShell code part 3 How to write PowerShell code part 4
