Handy SQL Server Functions Series (HSSFS) Part 2.0 - Prelude to Parsing Patterns Properly

- by Most Valuable Yak (Rob Volk)

In Part 1 of the series I wrote about 2 lesser-known and somewhat undocumented functions. In this part, I'm going to cover some familiar string functions like Substring(), Parsename(), Patindex(), and Charindex() and delve into their strengths and weaknesses. I'm also splitting this part up into sub-parts to help focus on a particular technique and/or problem with the technique, hence the Part 2.0. Consider this a composite post, or com-post, if you will. (It may just turn out to be a pile of sh_t after all) I'll be using a contrived example, perhaps the most frustratingly useful, or usefully frustrating, function in SQL Server: @@VERSION. Contrived, because there are better ways to get the information (which I'll cover later); frustrating, because of the way Microsoft formatted the value; and useful because it does have 1 or 2 bits of information not found elsewhere. First let's take a look at the output of @@VERSION: Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (Intel X86) Apr 2 2010 15:53:02 Copyright (c) Microsoft Corporation Developer Edition on Windows NT 5.1 <X86> (Build 2600: Service Pack 3) There are 4 lines, with lines 2-4 indented with a tab character. In case your browser (or this blog software) doesn't show it correctly, I gave each line a different color. While this PRINTs nicely, if you SELECT @@VERSION in grid mode it all runs together because it ignores carriage return/line feed (CR/LF) characters. Not fatal, but annoying. Note that @@VERSION's output will vary depending on edition and version of SQL Server, and also the OS it's installed on. Despite the differences, the output is laid out the same way and the relevant pieces are in the same order. I'll be using the following view for Parts 2.1 onward, so we have a nice collection of @@VERSION information: create view version(SQLVersion,VersionString) AS ( select 2000, 'Microsoft SQL Server 2000 - 8.00.2055 (Intel X86) Dec 16 2008 19:46:53 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 3)' union all select 2005, 'Microsoft SQL Server 2005 - 9.00.4053.00 (Intel X86) May 26 2009 14:24:20 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 3)' union all select 2008, 'Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (Intel X86) Apr 2 2010 15:53:02 Copyright (c) Microsoft Corporation Developer Edition on Windows NT 5.1 <X86> (Build 2600: Service Pack 3)' union all select 2005, 'Microsoft SQL Server 2005 - 9.00.3080.00 (Intel X86) Sep 6 2009 01:43:32 Copyright (c) 1988-2005 Microsoft Corporation Standard Edition on Windows NT 5.2 (Build 3790: Service Pack 2)' union all select 2008, 'Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (Hypervisor)' union all select 2008, 'Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Express Edition with Advanced Services (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (Hypervisor)' ) Feel free to add your own @@VERSION info if it's not already there. In Part 2.1 I'll focus on extracting the SQL Server version number (10.50.1600.1 in first example) and the Edition (Developer), but will have a solution that works with all versions. Stay tuned!

A view from the call center for the Nashville Flood telethon

- by Rob Foster

I want to break away from my usual topic of something technical and talk about what I experienced tonight while working in the call center for the Nashville Flood telethon, which was broadcast on WSMV, CNN, and The Weather Channel. We started receiving calls about 7pm local time and to be honest, I had no idea what to expect when going into this. I mean, I'm a pretty good talker, but this is different...We had a good script of what to say and how we were supposed to say it, as well as paper forms and pens that we used to collect information from people who wanted to donate their money to help. I took my first few calls pretty easily and it went pretty quick and easy. Everyone was upbeat and happy to be in the call center as well as people happy to be donating money. Pizza, snacks, and soft drinks were flowing well. Everyone is smiling and happy. :) About 3 or 4 calls into my night, I got a call from a lady that had lost 2 family members in West Nashville who drowned in the floods. She was crying when she called and I of course tried to console her. She told me how bad her situation was, losing family members and much of her neighborhood. After all this, she still just wanted to help other people. She was donating all the money that she could to the telethon and I want to share a direct quote from her: "I want to donate this instead of buying flowers for my family members' funeral because people out there need help.". Please let me pause while I get myself together <again>. That caught me so off guard (and still does). I had kids calling wanting to donate their allowance, open their piggy banks, whatever they could do. These are kids. Kids not much older than my boys. Kids who should be focused on buying the next cool video game or toy or whatever but wanted to do something. Everyone just seemed to want to help. I took calls from as far away as British Columbia as well and pretty much coast to coast. how cool is that? Yet another thing that caught me off guard. This kind lady that called from British Columbia told me how much she loved visiting Nashville and just hated to see this happen. I belive that she said that she will be attending the CMA Fest this year too. I was sure to tell her not to cancel her plans! :) It felt like every call I took (and I took A LOT, as did everyone else) was very personal and heartfelt. I've never had the privelage to do anything like this and fell lucky to have been able to help out with answering phones and logging donations. Nashville will bounce back very quickly, people are out there day and night helping each other, and the spirits are very high here. I hope that one day, my kids read this blog and better understand who they are, where they come from, and what the human spirt is and can be. I love this city, I love the people here, I love the culture and even more than ever am proud to say that this is me. This is us. We are Nashville!

What's up with LDoms: Part 9 - Direct IO

- by Stefan Hinker

In the last article of this series, we discussed the most general of all physical IO options available for LDoms, root domains. Now, let's have a short look at the next level of granularity: Virtualizing individual PCIe slots. In the LDoms terminology, this feature is called "Direct IO" or DIO. It is very similar to root domains, but instead of reassigning ownership of a complete root complex, it only moves a single PCIe slot or endpoint device to a different domain. Let's look again at hardware available to mars in the original configuration: root@sun:~# ldm ls-io NAME TYPE BUS DOMAIN STATUS ---- ---- --- ------ ------ pci_0 BUS pci_0 primary pci_1 BUS pci_1 primary pci_2 BUS pci_2 primary pci_3 BUS pci_3 primary /SYS/MB/PCIE1 PCIE pci_0 primary EMP /SYS/MB/SASHBA0 PCIE pci_0 primary OCC /SYS/MB/NET0 PCIE pci_0 primary OCC /SYS/MB/PCIE5 PCIE pci_1 primary EMP /SYS/MB/PCIE6 PCIE pci_1 primary EMP /SYS/MB/PCIE7 PCIE pci_1 primary EMP /SYS/MB/PCIE2 PCIE pci_2 primary EMP /SYS/MB/PCIE3 PCIE pci_2 primary OCC /SYS/MB/PCIE4 PCIE pci_2 primary EMP /SYS/MB/PCIE8 PCIE pci_3 primary EMP /SYS/MB/SASHBA1 PCIE pci_3 primary OCC /SYS/MB/NET2 PCIE pci_3 primary OCC /SYS/MB/NET0/IOVNET.PF0 PF pci_0 primary /SYS/MB/NET0/IOVNET.PF1 PF pci_0 primary /SYS/MB/NET2/IOVNET.PF0 PF pci_3 primary /SYS/MB/NET2/IOVNET.PF1 PF pci_3 primary All of the "PCIE" type devices are available for SDIO, with a few limitations. If the device is a slot, the card in that slot must support the DIO feature. The documentation lists all such cards. Moving a slot to a different domain works just like moving a PCI root complex. Again, this is not a dynamic process and includes reboots of the affected domains. The resulting configuration is nicely shown in a diagram in the Admin Guide: There are several important things to note and consider here: The domain receiving the slot/endpoint device turns into an IO domain in LDoms terminology, because it now owns some physical IO hardware. Solaris will create nodes for this hardware under /devices. This includes entries for the virtual PCI root complex (pci_0 in the diagram) and anything between it and the actual endpoint device. It is very important to understand that all of this PCIe infrastructure is virtual only! Only the actual endpoint devices are true physical hardware. There is an implicit dependency between the guest owning the endpoint device and the root domain owning the real PCIe infrastructure: Only if the root domain is up and running, will the guest domain have access to the endpoint device. The root domain is still responsible for resetting and configuring the PCIe infrastructure (root complex, PCIe level configurations, error handling etc.) because it owns this part of the physical infrastructure. This also means that if the root domain needs to reset the PCIe root complex for any reason (typically a reboot of the root domain) it will reset and thus disrupt the operation of the endpoint device owned by the guest domain. The result in the guest is not predictable. I recommend to configure the resulting behaviour of the guest using domain dependencies as described in the Admin Guide in Chapter "Configuring Domain Dependencies". Please consult the Admin Guide in Section "Creating an I/O Domain by Assigning PCIe Endpoint Devices" for all the details! As you can see, there are several restrictions for this feature. It was introduced in LDoms 2.0, mainly to allow the configuration of guest domains that need access to tape devices. Today, with the higher number of PCIe root complexes and the availability of SR-IOV, the need to use this feature is declining. I personally do not recommend to use it, mainly because of the drawbacks of the depencies on the root domain and because it can be replaced with SR-IOV (although then with similar limitations). This was a rather short entry, more for completeness. I believe that DIO can usually be replaced by SR-IOV, which is much more flexible. I will cover SR-IOV in the next section of this blog series.

Tuning Red Gate: #1 of Many

- by Grant Fritchey

Everyone runs into performance issues at some point. Same thing goes for Red Gate software. Some of our internal systems were running into some serious bottlenecks. It just so happens that we have this nice little SQL Server monitoring tool. What if I were to, oh, I don't know, use the monitoring tool to identify the bottlenecks, figure out the causes and then apply a fix (where possible) and then start the whole thing all over again? Just a crazy thought. OK, I was asked to. This is my first time looking through these servers, so here's how I'd go about using SQL Monitor to get a quick health check, sort of like checking the vitals on a patient. First time opening up our internal SQL Monitor instance and I was greeted with this: Oh my. Maybe I need to get our internal guys to read my blog. Anyway, I know that there are two servers where most of the load is. I'll drill down on the first. I'm selecting the server, not the instance, by clicking on the server name. That opens up the Global Overview page for the server. The information here much more applicable to the "oh my gosh, I have a problem now" type of monitoring. But, looking at this, I am seeing something immediately. There are four(4) drives on the system. The C:\ has an average read time of 16.9ms, more than double the others. Is that a problem? Not sure, but it's something I'll look at. It's write time is higher too. I'll keep drilling down, first, to the unclosed alerts on the server. Now things get interesting. SQL Monitor has a number of different types of alerts, some related to error states, others to service status, and then some related to performance. Guess what I'm seeing a bunch of right here: Long running queries and long job durations. If you check the dates, they're all recent, within the last 24 hours. If they had just been old, uncleared alerts, I wouldn't be that concerned. But with all these, all performance related, and all in the last 24 hours, yeah, I'm concerned. At this point, I could just start responding to the Alerts. If I click on one of the the Long-running query alerts, I'll get all kinds of cool data that can help me determine why the query ran long. But, I'm not in a reactive mode here yet. I'm still gathering data, trying to understand how the server works. I have the information that we're generating a lot of performance alerts, let's sock that away for the moment. Instead, I'm going to back up and look at the Global Overview for the SQL Instance. It shows all the databases on the server and their status. Then it shows a number of basic metrics about the SQL Server instance, again for that "what's happening now" view or things. Then, down at the bottom, there is the Top 10 expensive queries list: This is great stuff. And no, not because I can see the top queries for the last 5 minutes, but because I can adjust that out 3 days. Now I can see where some serious pain is occurring over the last few days. Databases have been blocked out to protect the guilty. That's it for the moment. I have enough knowledge of what's going on in the system that I can start to try to figure out why the system is running slowly. But, I want to look a little more at some historical data, to understand better how this server is behaving. More next time.

From DBA to Data Analyst

- by Denise McInerney

Cross posted from the PASS Blog There is a lot changing in the data professional’s world these days. More data is being produced and stored. More enterprises are trying to use that data to improve their products and services and understand their customers better. More data platforms and tools seem to be crowding the market. For a traditional DBA this can be a confusing and perhaps unsettling time. It’s also a time that offers great opportunity for career growth. I speak from personal experience. We sometimes refer to the “accidental DBA”, the person who finds herself suddenly responsible for managing the database because she has some other technical skills. While it was not accidental, six months ago I was unexpectedly offered a chance to transition out of my DBA role and become a data analyst. I have since come to view this offer as a gift, though at the time I wasn’t quite sure what to do with it. Throughout my DBA career I’ve gotten support from my PASS friends and colleagues and they were the first ones I turned to for counsel about this new situation. Everyone was encouraging and I received two pieces of valuable advice: first, leverage what I already know about data and second, work to understand the business’ needs. Bringing the power of data to bear to solve business problems is really the heart of the job. The challenge is figuring out how to do that. PASS had been the source of much of my technical training as a DBA, so I naturally started there to begin my Business Intelligence education. Once again the Virtual Chapter webinars, local chapter meetings and SQL Saturdays have been invaluable. I work in a large company where we are fortunate to have some very talented data scientists and analysts. These colleagues have been generous with their time and advice. I also took a statistics class through Coursera where I got a refresher in statistics and an introduction to the R programming language. And that’s not the end of the free resources available to someone wanting to acquire new skills. There are many knowledgeable Business Intelligence and Analytics professionals who teach through their blogs. Every day I can learn something new from one of these experts. Sometimes we plan our next career move and sometimes it just happens. Either way a database professional who follows industry developments and acquires new skills will be better prepared when change comes. Take the opportunity to learn something about the changing data landscape and attend a Business Intelligence, Business Analytics or Big Data Virtual Chapter meeting. And if you are moving into this new world of data consider attending the PASS Business Analytics Conference in April where you can meet and learn from those who are already on that road. It’s been said that “the only thing constant is change.” That’s never been more true for the data professional than it is today. But if you are someone who loves data and grasps its potential you are in the right place at the right time.

Windows Phone 7 Series - Tools and Resources

- by TechTwaddle

Unless you've been living in the caves of Lascaux for the past couple of days, you probably know what's happening in the world of Windows Phone. Microsoft unveiled the developer tools required to develop applications and games for Windows Phone 7 at MIX10 a couple of days back. Silverlight and XNA being the major frameworks, no big surprise there. And the best news of all is that all the development tools are free! So if you are planning to develop apps for Windows Phone 7, read on. The first place, or more appropriately hub, for you is the Windows Phone Developer Portal. It has most of the information you need to get you started. Now there is a ton of information available at other places too. In this post, I take time to put all the information that I found useful at one place, and I'll keep updating this as and when I find new stuff. Setting up the development environment 1. Install Windows Phone Developer Tools CTP (Community Technology Preview) This will install Visual Studio 2010 Express, Silverlight, XNA framework and emulator for Windows Phone 7. It also installs a few support tools. 2. Expression Blend 4 for Windows Phone: - Install Expression Blend 4 beta - Install Expression Blend Add-in Preview for Windows Phone - Install Expression Blend SDK Preview for Windows Phone Installing the above tools should set your machine up for development. I installed the tools on my Windows Vista SP1 machine and the process went smoothly without running into any major hitch. Note that the tools won't install on Windows XP, read the release notes of the CTP. Resources and Documentation 1. Microsoft Windows Phone 7 Series Developer Training Kit 2. Programming Windows Phone 7 Series by Charles Petzold. Contains few chapters only. Gives a good preview. 3. MSDN documentation for Windows Phone 7 Development 4. A sample chapter from Learning Windows Phone Programming [PDF] by Yochay Kiriaty and Jaime Rodriguez. Complete book will be available at a later time. 5. Windows Phone 7 Developer Forum - where you can ask questions and problems you run into and the experts are there to help you. 6. For Silverlight visit silverlight.net and for XNA game development, the XNA Creators Club is the place to go, also make sure you follow Michael Klutcher's and Shawn Hargreaves' blog. 7. And finally the MIX'10 website. Most of the sessions will be available for download later (some are already available). Click on the Windows Phone tag to get all the session details and downloads. If you are completely new to Silverlight and XNA (like me), and C# makes some sense to you then I suggest you go through the Developer Training Kit. It gives a good start and ramps you up pretty quickly.

What Counts For A DBA: ESP

- by Louis Davidson

Now I don’t want to get religious here, and I’m not going to, but what I’m going to describe in this ‘What Counts for a DBA’ installment sometimes feels like magic. Often I will spend hours thinking about the solution to a design issue or coding problem, working diligently to try to come up with a solution and then finally just give up with the feeling that I’m not even qualified to be a data entry clerk, much less a data architect. At this point I often take a walk (or sometimes a nap), and then it hits me. I realize that I have the answer just sitting in my brain, ready to implement. This phenomenon is not limited to walks either; it can happen almost any time after I stop my obsession about a problem. I call this phenomena ESP (or Extra-Sensory Programming.) Another term for this could be ‘sleeping on it’, and while the idiom tends to mean to let time pass to actively think about a problem, sleeping on a problem also lets you relax and let your brain do the work. I first noticed this back in my college days when I would play video games for hours on end. We would get stuck deep in some dungeon unable to find a way out, playing for days on end until we were beaten down tired. Once we gave up and walked away, the solution would usually be there waiting for one of us before we came back to play the next day. Sometimes it would be in the form of a dream, and sometimes it would just be that the problem was now easy to solve when we started to play again. While it worked great for video games, it never occurred when I studied English Literature for hours on end, or even when I worked for the same sort of frustrating hours attempting to solve a homework problem in Calculus. I believe that the difference was that I was passionate about the video game, and certainly far less so about homework where people used the word “thou” instead of “you” or x to represent a number. This phenomenon occurs somewhat more often in my current work as a professional data programmer, because I am very passionate about SQL and love those aspects of my career choice. Every day that I get to draw a new data model to solve a customer issue, or write a complex SELECT statement to ferret out the answer to a complex data question, is a great day. I hope it is the same for any reader of this blog. But, unfortunately, while the day on a whole is great, a heck of a lot of noise is generated in work life. There are the typical project deadlines, along with the requisite project manager sitting on your shoulders shouting slogans to try to make you to go faster: Add in office politics, and the occasional family issues that permeate the mind, and you lose the ability to think deeply about any problem, not to mention occasionally forgetting your own name. These office realities coupled with a difficult SQL problem staring at you from your widescreen monitor will slowly suck the life force out of your body, making it seem impossible to solve the problem This is when the walk starts; or a nap. Maybe you hide from the madness under your desk like George Costanza hides from Steinbrenner on Seinfeld. Forget about the problem. Free your mind from the insanity of the problem and your surroundings. Then let your training and education deep in your brain take over and see if it will passively do the rest for you. If you don’t end up with a solution, the worst case scenario is that you have a bit of exercise or rest, and you won’t have heard the phrase “better is the enemy of good enough” even once…which certainly will do your brain some good. Once you stop expecting whipping your brain for information, inspiration may just strike and instead of a humdrum solution you find a solution you hadn’t even considered, almost magically. So, my beloved manager, next time you have an urgent deadline and you come across me taking a nap, creep away quietly because I’m working, doing some extra-sensory programming.

OTN ArchBeat Top 10 for September 2012

- by Bob Rhubart

The results are in... Listed below are the Top 10 most popular items shared via the OTN ArchBeat Facebook Page for the month of September 2012. The Real Architects of Los Angeles - OTN Architect Day - Oct 25 No gossip. No drama. No hair pulling. Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen. Oracle 11gR2 RAC on Software Defined Network (SDN) (OpenvSwitch, Floodlight, Beacon) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation. Process Oracle OER Events using a simple Web Service | Bob Webster Bob Webster's post "provides an example of a simple web service that processes Oracle Enterprise Repository (OER) Events. The service receives events from OER and utilizes the OER REX API to implement simple OER automations for selected event types." Understanding Oracle BI 11g Security vs Legacy Oracle BI 10g | Christian Screen "After conducting a large amount of Oracle BI 10g to Oracle BI 11g upgrades and after writing the Oracle BI 11g book,"says Oracle ACE Christian Screen, "I still continually get asked one of the most basic questions regarding security in Oracle BI 11g; How does it compare to Oracle BI 10g? The trail of questions typically goes on to what are the differences? And, how do we leverage our current Oracle BI 10g security table schema in Oracle BI 11g?" OIM-OAM-OAAM integration using TAP – Request Flow you must understand!! | Atul Kumar Atul Kumar's post addresses "key points and request flow that you must understand" when integrating three Oracle Identity Management product Oracle Identity Management, Oracle Access Management, and Oracle Adaptive Access Manager. Adding a runtime LOV for a taskflow parameter in WebCenter | Yannick Ongena Oracle ACE Yannick Ongena illustrates how to customize the parameters tab for a taskflow in WebCenter. Tips on Migrating from AquaLogic .NET Accelerator to WebCenter WSRP Producer for .NET | Scott Nelson "It has been a very winding path and this blog entry is intended to share both the lessons learned and relevant approaches that led to those learnings," says Scott Nelson. "Like most journeys of discovery, it was not a direct path, and there are notes to let you know when it is practical to skip a section if you are in a hurry to get from here to there." 15 Lessons from 15 Years as a Software Architect | Ingo Rammer In this presentation from the GOTO Conference in Copenhagen, Ingo Rammer shares 15 tips regarding people, complexity and technology that he learned doing software architecture for 15 years. WebCenter Content (WCC) Trace Sections | ECM Architect ECM Architect Kevin Smith shares a detailed technical post covering WebCenter Content (WCC) Trace Sections. Thought for the Day "Eventually everything connects - people, ideas, objects. The quality of the connections is the key to quality per se." — Charles Eames (June 17, 1907 – August 21, 1978) Source: SoftwareQuotes.com

forEach and Facelets - a bugfarm just waiting for harvest

- by Duncan Mills

An issue that I've encountered before and saw again today seems worthy of a little write-up. It's all to do with a subtle yet highly important difference in behaviour between JSF 2 running with JSP and running on Facelets (.jsf pages). The incident I saw today can be seen as a report on the ADF EMG bugzilla (Issue 53) and in a blog posting by Ulrich Gerkmann-Bartels who reported the issue to the EMG. Ulrich's issue nicely shows how tricky this particular gochya can be. On the surface, the problem is squarely the fault of MDS but underneath MDS is, in fact, innocent. To summarize the problem in a simpler testcase than Ulrich's example, here's a simple fragment of code: <af:forEach var="item" items="#{itemList.items}"> <af:commandLink id="cl1" text="#{item.label}" action="#{item.doAction}" partialSubmit="true"/> </af:forEach> Looks innocent enough right? We see a bunch of links printed out, great. The issue here though is the id attribute. Logically you can kind of see the problem. The forEach loop is creating (presumably) multiple instances of the commandLink, but only one id is specified - cl1. We know that IDs have to be unique within a JSF component tree, so that must be a bad thing? The problem is that JSF under JSP implements some hacks when the component tree is generated to transparently fix this problem for you. Behind the scenes it ensures that each instance really does have a unique id. Really nice of it to do so, thank you very much. However, (you could see this coming), the same is not true when running with Facelets (this is under 11.1.2.n) in that case, what you put for the id is what you get, and JSF does not mess around in the background for you. So you end up with a component tree that contains duplicate ids which are only created at runtime. So subtle chaos can ensue. The symptoms are wide and varied, from something pretty obscure such as the combination Ulrich uncovered, to something as frustrating as your ActionListener just not being triggered. And yes I've wasted hours on just such an issue. The Solution Once you're aware of this one it's really simple to fix it, there are two options: Remove the id attribute on components that will cause some kind of submission within the forEach loop altogether and let JSF do the right thing in generating them. Then you'll be assured of uniqueness. Use the var attribute of the loop to generate a unique id for each child instance. for example in the above case: <af:commandLink id="cl1_#{item.index}" ... />. So one to watch out for in your upgrades to JSF 2 and one perhaps, for your coding standards today to prepare you for. For completeness, here's the reference to the underlying JSF issue that's at the heart of this: JAVASERVERFACES-1527

Using Teleriks new LINQ implementation to connect to MySQL

Last week Telerik released a new LINQ implementation that is simple to use and produces domain models very fast. Built on top of the enterprise grade OpenAccess ORM, you can connect to any database that OpenAccess can connect to such as: SQL Server, MySQL, Oracle, SQL Azure, VistaDB, etc. Today I will show you how to build a domain model using MySQL as your back end. To get started, you have to download MySQL 5.x and the MySQL Workbench and also, as my colleague Alexander Filipov at Telerik reminded me, make sure you install the MySQL .NET Connector, which is available here. I like to use Northwind, ok it gives me the warm and fuzzies, so I ran a script to produce Northwind on my MySQL server. There are many ways you can get Northwind on your MySQL database, here is a helpful blog to get your started. I also manipulated the first record to indicate that I am in MySQL and gave a look via the MySQL Workbench. Ok, time to build our model! Start up the Domain Model wizard by right clicking on the project in Visual Studio (I have a Web project) and select Add|New Item and choose Telerik OpenAccess Domain Model from the new item list. When the wizard comes up, choose MySQL as your back end and enter in the name of your saved MySQL connection. If you dont have a saved MySQL connection set up in Visual Studio, click on New Connection and enter in the proper connection information. *Note, this is where you need to have the MySQL .NET connector installed. After you set your connection to the MySQL database server, you have to choose which tables to include in your model. Just for fun, I will choose all of them. Give your model a name, like NorthwindEntities and click finish. That is it. Now lets consume the model with ASP .net. I created a simple page that also has a GridView on it. On my page load I wrote this code, by now it should look very familiar, a simple LINQ query filtering customers by country (Germany) and binding the results to the grid. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: if (!IsPostBack) 4: { 5: //a reference to the data context 6: NorthwindEntities dat = new NorthwindEntities(); 7: //LINQ Statement 8: var result = from c in dat.Customers 9: where c.Country == "Germany" 10: select c; 11: //Databinding to the Gridview 12: GridView1.DataSource = result; 13: GridView1.DataBind(); 14: } 15: } .csharpcode, .csharpcode pre{ font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em;}.csharpcode .lnum { color: #606060; } F5 produces the following. Tomorrow Ill show how to take the same model and create an Astoria/OData data feed. Technorati Tags: MySQL Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

What DX level does my graphics card support? Does it go to 11?

- by Daniel Moth

Recently I run into a situation that I have run into quite a few times. Someone encounters a machine and the question arises: "Is there a DirectX 11 card in this machine?". Typically the reason you are interested in that is because cards with DirectX 11 drivers fully support DirectCompute (and by extension C++ AMP) for GPGPU programming. The driver specifically is WDDM (1.1 on Windows 7 and Windows 8 introduces WDDM 1.2 with cool new capabilities). There are many ways for figuring out if you have a DirectX11 card, so here are the approaches that you can use, with a bonus right at the end of the post. Run DxDiag WindowsKey + R, type DxDiag and hit Enter. That is the DirectX diagnostic tool, which unfortunately, only tells you on the "System" tab what is the highest version of DirectX installed on your machine. So if it reports DirectX 11, that doesn't mean you have a DX11 driver! The "Display" tab has a promising "DDI version" label, but unfortunately that doesn't seem to be accurate on the machines I've tested it with (or I may be misinterpreting its use). Either way, this tool is not the one you want for this purpose, although it is good for telling you the WDDM version among other things. Use the Microsoft hardware page There is a Microsoft Windows 7 compatibility center, that lists all hardware (tip: use the advanced search) and you could try and locate your device there… good luck. Use Wikipedia or the hardware vendor's website Use the Wikipedia page for the vendor cards, for both nvidia and amd. Often this information will also be in the specifications for the cards on the IHV site, but is is nice that wikipedia has a single page per vendor that you can search etc. There is a column in the tables for API support where you can see the DirectX version. Check if it is one of these recommended DX11 cards You may not have a DirectX 11 card and are interested in purchasing one. While I am in no position to make recommendations, I will list here some cards from two big IHVs that we know are DirectX 11 capable. Some AMD (aka ATI) cards Low end, inexpensive DX11 hardware: Radeon 5450, 5550, 6450, 6570 Mid range (decent perf, single precision): Radeon 5750, 5770, 6770, 6790 High end (capable of double precision): Radeon 5850, 5870, 6950, 6970 Single precision APUs: AMD E-Series APUs AMD A-Series APUs Some NVIDIA cards Low end, inexpensive DX11 hardware: GeForce GT430, GT 440, GT520, GTS 450 Quadro 400, 600 Mid-range (decent perf, single precision): GeForce GTX 460, GTX 550 Ti, GTX 560, GTX 560 Ti Quadro 2000 High end (capable of double precision): GeForce GTX 480, GTX 570, GTX 580, GTX 590, GTX 595 Quadro 4000, 5000, 6000 Tesla C2050, C2070, C2075 Get the DirectX SDK and run DirectX Caps Viewer Download and install the June 2010 DirectX SDK. As part of that you now have the DirectX Capabilities Viewer utility (find it in your start menu by searching for "DirectX Caps Viewer", the filename is DXCapsViewer.exe). It will list all your devices (emulated, and real hardware ones) under the first node. Expand the hardware entries and then expand again the Direct3D 11 folder. If you see D3D_FEATURE_LEVEL_11_ under that, then your card supports feature level 11 which means it supports DirectCompute and C++ AMP. In the following screenshot of one of my old laptops, the card only goes to feature level 10. Run a utility from the web that just tells you! Of course, writing some C++ AMP code that enumerates accelerators and lists the ones that are capable is trivial. However that requires that you have redistributed the runtime, so a more broadly applicable approach is to use the DX APIs directly to enumerate the DX11 capable cards. That is exactly what the development lead for C++ AMP has done and he describes and shares that utility at this post. Comments about this post by Daniel Moth welcome at the original blog.

SharePoint Saturday DC

- by Mark Rackley

Wow… did you see this thing? 927 attendees? An exhibition hall full of vendors? 94 speakers? 100 sessions?? Insane is a word that comes to mind… SharePoint Saturday DC was definitely epic as far as SharePoint Saturdays go. I got to catch up with a lot of friends and make some new ones. Met a couple of fans of the blog (hello ladies…;)) Did you know that people actually read this thing? I guess that means I need to stop putting so much garbage on here and more content. I’ll get right on that as soon as I find out how to add 6 hours to each day. Anyway, once again I did my “Wrapping Your Head Around the SharePoint Beast” session. I tweaked it even more from Huntsville and presented to a packed room with some people sitting on the floor and standing in the aisles. It was a great crowd, very interactive and they seemed interested at least. Thank you guys so much for attending and please feel free to tell me of any suggestions you have to make the presentation better. This is one of the presentations that will probably never die. Everyone beginning SharePoint development needs a good introduction and starting point. My goal is to make this THE session to see on the subject. So, a little interesting data about my class. Half of the room was brand new to SharePoint and only one person was using 2010. That tells me that this session still has legs and that 2007 isn’t going anywhere anytime soon. I know my organization will be using 2007 for at least a couple more years. Oh yeah… the slide deck? Here it is: SharePoint Saturday DC Slide Deck So, SharePoint Saturday was truly tremendous and if you weren’t there you missed out. @meetdux, @usher, and the rest of their crew did a spectacular job. You guys rock and are a huge asset to the community. Thanks for allowing me to speak. What’s up next for me? I’m so glad you asked…. SHAREPOINT SATURDAY OZARKS IS JUNE 12TH! Although SharePoint Saturday Ozarks on June 12 in Harrison Arkansas will be a much more intimate event than DC, it promises to be a most memorable event. We’ve got over 30 speakers and sessions, some cool stuff to give away, and we’re going floating down the Buffalo River on the 13th. Let’s see you do THAT in DC. :) Anyway, I hope to see you there and I would truly appreciate any help you can do to help publicize the event. We just got internet here in the hills and most people here are still looking for the “any” key….

Social Technology and the Potential for Organic Business Networks

- by Michael Snow

Guest Blog Post by: Michael Fauscette, IDCThere has been a lot of discussion around the topic of social business, or social enterprise, over the last few years. The concept of applying emerging technologies from the social Web, combined with changes in processes and culture, has the potential to provide benefits across the enterprise over a wide range of operations impacting employees, customers, partners and suppliers. Companies are using social tools to build out enterprise social networks that provide, among other things, a people-centric collaborative and knowledge sharing work environment which over time can breakdown organizational silos. On the outside of the business, social technology is adding new ways to support customers, market to prospects and customers, and even support the sales process. We’re also seeing new ways of connecting partners to the business that increases collaboration and innovation. All of the new "connectivity" is, I think, leading businesses to a business model built around the concept of the network or ecosystem instead of the old "stand-by-yourself" approach. So, if you think about businesses as networks in the context of all of the other technical and cultural change factors that we're seeing in the new information economy, you can start to see that there’s a lot of potential for co-innovation and collaboration that was very difficult to arrange before. This networked business model, or what I've started to call “organic business networks,” is the business model of the information economy.The word “organic” could be confusing, but when I use it in this context, I’m thinking it has similar traits to organic computing. Organic computing is a computing system that is self-optimizing, self-healing, self-configuring, and self-protecting. More broadly, organic models are generally patterns and methods found in living systems used as a metaphor for non-living systems.Applying an organic model, organic business networks are networks that represent the interconnectedness of the emerging information business environment. Organic business networks connect people, data/information, content, and IT systems in a flexible, self-optimizing, self-healing, self-configuring, and self-protecting system. People are the primary nodes of the network, but the other nodes — data, content, and applications/systems — are no less important.A business built around the organic business network business model would incorporate the characteristics of a social business, but go beyond the basics—i.e., use social business as the operational paradigm, but also use organic business networks as the mode of operating the business. The two concepts complement each other: social business is the “what,” and the organic business network is the “how.”An organic business network lets the business work go outside of traditional organizational boundaries and become the continuously adapting implementation of an optimized business strategy. Value creation can move to the optimal point in the network, depending on strategic influencers such as the economy, market dynamics, customer behavior, prospect behavior, partner behavior and needs, supply-chain dynamics, predictive business outcomes, etc.An organic business network driven company is the antithesis of a hierarchical, rigid, reactive, process-constrained, and siloed organization. Instead, the business can adapt to changing conditions, leverage assets effectively, and thrive in a hyper-connected, global competitive, information-driven environment.To hear more on this topic – I’ll be presenting in the next webcast of the Oracle Social Business Thought Leader Webcast Series - “Organic Business Networks: Doing Business in a Hyper-Connected World” this coming Thursday, June 21, 2012, 10:00 AM PDT – Register here

SQL SERVER – Monitoring SQL Server Database Transaction Log Space Growth – DBCC SQLPERF(logspace) – Puzzle for You

- by pinaldave

First of all – if you are going to say this is very old subject, I agree this is very (very) old subject. I believe in earlier time we used to have this only option to monitor Log Space. As new version of SQL Server released we all equipped with DMV, Performance Counters, Extended Events and much more new enhancements. However, during all this year, I have always used DBCC SQLPERF(logspace) to get the details of the logs. It may be because when I started my career I remember this command and it did what I wanted all the time. Recently I have received interesting question and I thought, I should request your help. However, before I request your help, let us see traditional usage of DBCC SQLPERF(logspace). Every time I have to get the details of the log I ran following script. Additionally, I liked to store the details of the when the log file snapshot was taken as well so I can go back and know the status log file growth. This gives me a fair estimation when the log file was growing. CREATE TABLE dbo.logSpaceUsage ( id INT IDENTITY (1,1), logDate DATETIME DEFAULT GETDATE(), databaseName SYSNAME, logSize DECIMAL(18,5), logSpaceUsed DECIMAL(18,5), [status] INT ) GO INSERT INTO dbo.logSpaceUsage (databaseName, logSize, logSpaceUsed, [status]) EXEC ('DBCC SQLPERF(logspace)') GO SELECT * FROM dbo.logSpaceUsage GO I used to record the details of log file growth every hour of the day and then we used to plot charts using reporting services (and excel in much earlier times). Well, if you look at the script above it is very simple script. Now here is the puzzle for you. Puzzle 1: Write a script based on a table which gives you the time period when there was highest growth based on the data stored in the table. Puzzle 2: Write a script based on a table which gives you the amount of the log file growth from the beginning of the table to the latest recording of the data. You may have to run above script at some interval to get the various data samples of the log file to answer above puzzles. To make things simple, I am giving you sample script with expected answers listed below for both of the puzzle. Here is the sample query for puzzle: -- This is sample query for puzzle CREATE TABLE dbo.logSpaceUsage ( id INT IDENTITY (1,1), logDate DATETIME DEFAULT GETDATE(), databaseName SYSNAME, logSize DECIMAL(18,5), logSpaceUsed DECIMAL(18,5), [status] INT ) GO INSERT INTO dbo.logSpaceUsage (databaseName, logDate, logSize, logSpaceUsed, [status]) SELECT 'SampleDB1', '2012-07-01 7:00:00.000', 5, 10, 0 UNION ALL SELECT 'SampleDB1', '2012-07-01 9:00:00.000', 16, 10, 0 UNION ALL SELECT 'SampleDB1', '2012-07-01 11:00:00.000', 9, 10, 0 UNION ALL SELECT 'SampleDB1', '2012-07-01 14:00:00.000', 18, 10, 0 UNION ALL SELECT 'SampleDB3', '2012-06-01 7:00:00.000', 5, 10, 0 UNION ALL SELECT 'SampleDB3', '2012-06-04 7:00:00.000', 15, 10, 0 UNION ALL SELECT 'SampleDB3', '2012-06-09 7:00:00.000', 25, 10, 0 GO Expected Result of Puzzle 1 You will notice that there are two entries for database SampleDB3 as there were two instances of the log file grows with the same value. Expected Result of Puzzle 2 Well, please a comment with valid answer and I will post valid answers with due credit next week. Not to mention that winners will get a surprise gift from me.

How to Build Services from Legacy Applications

- by Chris Falter

The SOA consultants invaded the executive suite at your company or agency, preached the true religion, and converted the unbelievers. Now by divine imperative you must convert your legacy applications into a suite of reusable services. But as usual, you lack the time and resources that you need in order to develop the services properly. So you googled or bing’ed, found this blog post, and began crying in gratitude. Yes, as the title implies, I am going to reveal my easy, 3-step, works-every-time process for converting silos of legacy applications into the inventory of services your CIO has been dreaming about. So just close your eyes and count to 3 … now open them … and here it is…. Not. While wishful thinking is too often the coin of the IT realm, even the most naive practitioner knows that converting legacy applications into reusable services requires more than a magic wand. The reason is simple: if your starting point is your legacy applications, then you will simply be bolting a web service technology layer on top of your legacy API. And that legacy API is built in the image of the silo applications. Enter the wide gate of the legacy API, follow the broad path of generating service interfaces from existing code, and you will arrive at the siloed enterprise destruction that you thought you were escaping. The Straight and Narrow Path This past week I had the opportunity to learn how the FBI Criminal Justice Information Systems department has been transitioning from silo applications to a service inventory. Lafe Hutcheson, IT Specialist in the architecture group and fellow attendee at an SOA Architect Certification Workshop, was my guide. Lafe has survived the chaos of an SOA initiative, so it is not surprising that he was able to return from a US Army deployment to Kabul, Afghanistan with nary a scratch. According to Lafe, building their service inventory is a three-phase process: Model a business process. This requires intense collaboration between the IT and business wings of the organization, of course. The FBI uses IBM Websphere tools to model the process with BPMN. Identify candidate services to facilitate the business process. Convert the BPMN to an executable BPEL orchestration, model and develop the services, and use a BPEL engine to run the process. The FBI uses ActiveVOS for orchestration services. The 12 Step Program to End Your Legacy API Addiction Thomas Erl has documented a process for building a web service inventory that is quite similar to the FBI process. Erl’s process adds a technology architecture definition phase, which allows for the technology environment to influence the inventory blueprint. For example, if you are using an enterprise service bus, you will probably not need to build your own utility services for logging or intermediate routing. Erl also lists a service-oriented analysis phase that highlights the 12-step process of applying the principles of service orientation to modeling your services. Erl depicts the modeling of a service inventory as an iterative process: model a business process, define the relevant technology architecture, define the service inventory blueprint, analyze the services, then model another business process, rinse and repeat. (Astute readers will note that Erl’s diagram, restricted to analysis and modeling process, does not include the implementation phase that concludes the FBI service development methodology.) The service-oriented analysis phase is where you find the 12 steps that will free you from your legacy API addiction. In a nutshell, you identify the steps in the process that need services; identify the different types of services (agnostic entity services, service compositions, and utility services) that are required; apply service-orientation principles; and normalize the inventory into cohesive service models. Rather than discuss each of the 12 steps individually, I will close by simply referring my readers to Erl’s explanation.

Get Your Enterprise Working With Oracle On Track Communication 1.0

- by Josh Lannin

The On Track Development team is very pleased to announce that today On Track is available for our customers to download and evaluate. To learn more about what On Track does start with our whitepaper and datasheet. If you are a developer, take a look at our documentation and samples posted to our OTN page. For this first blog post, I’ll be speaking to several notable points about our product. Graceful Escalation via Conversations: On Track addresses the “Collaboration Problem” through a single guiding principle – graceful escalation – within the construct of a Conversation. In On Track, collaboration is based on a context (called a “Conversation”) that gracefully escalates in form, structure, and content, as dictated by the particular needs of a given collaboration. Within that context, On Track provides a rich set of tools to choose from. These tools provide for communication, coordination, content management, organization, decision making, and analysis -- all essential aspects of collaboration, but not all of them are essential all of the time. Every collaborative interaction will evolve differently. Some will evolve to represent work spreading over the course of years and involving a large, distributed team, while others may involve few people and not evolve at all. Regardless, all collaborative contexts are built from the same parts, utilize the same concepts, and start the same way. The principle of graceful escalation is that you only use the tools and structure you need; so you only incur the complexity you need. Purposeful Collaboration: Through application integration, On Track Conversations bring enterprise application users the communication and collaboration capabilities required to complete business process. By association with specific processes or business objects conversations extend the possible interactions and broaden participation to internal or external non-application users and provide a sophisticated interaction experience, all the while enhancing the data set within the owning application. Purposeful collaboration not only needs to happen in the context of applications, it must support a full range of real-time and long-running interactions to provide the greatest value. Multi Client, Multi Modal: This On Track 1.0 product release includes the same day availability of multiple clients, including iPhone and iPad applications which are now available on the Apple Store, a fully capable and accessible Outlook Add-In, along with our browser web client. With each client we have sought to leverage the strengths of each unique device- our iPhone client supports picture and voice posts, the iPad is optimized for meeting room situations and document viewing, and our Outlook add-in allows you to take emails in context and bring them into On Track. In addition to supporting a diverse array of clients, On Track provides a unified multi modal experience support starting with basic messages moving through to integrated documents with live annotations, snapshots, application sharing, and voice. Next Generation Web Architecture: We believe On Track will help move the bar higher for what users can expect from all web applications, most notably ones that involve real-time activity. On Track is built from the ground up with an innovative, real-time architecture that leverages the extensive push capabilities of our server. Whether you are receiving a new message, viewing where crowds of people are collaborating, or doing live annotation on a document with a set of people, that information comes to you immediately without refreshes or moving back and forth between pages. We’ve leveraged this core architecture across the product experience and raised the user experience bar for this type of application. As well these capabilities are based on open standards and protocols, and are fully extensible by anyone- enabling sophisticated integrations to be created with a wide variety of both legacy and next-generation applications. Agile Product Development: As a product team we operate using continuous feedback and modified agile development methodologies. We have thousands of active internal Oracle users who have helped pilot our product for critical business functions, and the On Track product development team uses our product as our primary vehicle for all our collaboration. Additionally we been working with early access customers who are adopting our technology and providing us valuable feedback - which our process has rapidly realized in improvements to our software. On Track agility extends to our server as well, which is built to scale, and is very simple to install and configure. We are pleased to make this product announcement and encourage you to join us on Facebook or follow us on Twitter, as well as checking back here for the latest product information.

5 Ways to Celebrate the Release of Internet Explorer 9

- by David Wesst

The day has finally come: Microsoft has released a web browser that is awesome. On Monday night, Microsoft officially introduced the world to the latest edition to its product family: Internet Explorer 9. That makes March 14, 2011 (also known as PI day) the official birthday of Microsoft’s rebirth in the world of web browsing. Just like any big event, you take some time to celebrate. Here are a few things that you can do to celebrate the return of Internet Explorer. 1. Download It If you’re not a big partier, that’s fine. The one thing you can do (and definitely should) is download it and give it a shot. Sure, IE may have disappointed you in the past, but believe me when I say they really put the effort in this time. The absolute least you can do is give it a shot to see how it stands up against your favourite browser. 2. Get yourself an HTML5 Shirt One of the coolest, if not best parts of IE9 being released is that it officially introduces HTML5 as a fully supported platform from Microsoft. IE9 supports a lot of what is already defined in the HTML5 technical spec, which really demonstrates Microsoft’s support of the new standard. Since HTML5 is cool on the web, it means that it is cool to wear it too. Head over to html5shirt.com and get yourself, or your staff, or your whole family, an HTML5 shirt to show the real world that you are ready for the future of the web. 3. HTML5-ify Something Okay, so maybe a shirt isn’t enough for you. Maybe you need start using HTML5 for real. If you have a blog, or a website, or anything out there on the web, celebrate IE9 adding some HTML5 to your site. Whether that is updating old code, adding something new, or just changing your WordPress theme, definitely take a look at what HTML5 can do for you. 4. Help Kill Old IE and Upgrade your Organization See this? This is sad. Upgrading web browsers in an large enterprise or organization is not a trivial task. A lot of companies will use the excuse of not having the resources to upgrade legacy web applications they were built for a specific version of IE and it doesn’t render correctly in legacy browsers. Well, it’s time to stop the excuses. IE9 allows you to define what version of Internet Explorer you would like it to emulate. It takes minimal effort for the developer, and will get rid of the excuses. Show your IT manager or software development team this link and show them how easy it is to make old code render right in the latest and greatest from the IE team. 5. Submit an Entry for DevUnplugged So, you’ve made it to number five eh? Well then, you must be pretty hardcore to make it this far down the list. Fine, let’s take it to the next level and build an HTML5 game. That’s right. A game. Like a video game. HTML5 introduces some amazing new features that can let you build working video games using HTML5, CSS3, and JavaScript. Plus, Microsoft is celebrating the launch of IE9 with a contest where you can submit an HTML5 game (or audio application) and have a chance to win a whack of cash and other prizes. Head here for the full scoop and rules for the DevUnplugged. This post also appears at http://david.wes.st

MPI Cluster Debugger launch integration in VS2010

Let's assume that you have all the HPC bits installed and that you have existing MPI code (or you created a "Hello World" project using the MPI project template). Of course, you create a single MPI application and at runtime it will correspond to multiple processes (of the same app) launched on multiple nodes (i.e. machines) on the cluster. So how do you debug such a situation by simply hitting the familiar "F5" keystroke (i.e. Debug - Start Debugging)?WATCH IT INSTEAD OF READING ABOUT ITIf you can't bear to read through all the details below, just watch this 19-minute screencast explaining this VS2010 feature. Alternatively, or even additionally, keep on reading.REQUIREMENTWhen you debug an MPI application, you would want the copying of resources from your client machine (where Visual Studio is installed) to each compute node (where Windows HPC Server is installed) to take place automatically for you. 'Resources' in the previous sentence includes your application binary, plus any binary or data dependencies it may have, plus PDBs if needed, plus the debug CRT of the correct bitness, plus msvsmon for remote debugging to work. You would also want, after copying is complete, to have your app and msvsmon launched and attached so that you can hit breakpoints back in Visual Studio on your client machine. All these thing that you would want are delivered in VS2010.STEPS TO F51. In your MPI project where you have placed a breakpoint go to Project Properties - Configuration Properties - Debugging. Ensure the "Debugger to launch" combo box value is set to MPI Cluster Debugger.2. There are a whole bunch of properties here and typically you can ignore all of them except one: Run Environment. By default it is set to run 1 process on your local machine and if you change the number after that to, for example, 4 it will launch 4 processes of your app on your local machine.You want this to run on your cluster though, so go to the dropdown arrow at the end of the Run Environment cell and open it to expose the "Edit Hpc node" menu which opens the Node Selector dialog:In this dialog you can enter (or pick from a list) the cluster head node name and then the number of processes you want to execute on the cluster and then hit OK and… you are done.3. Press F5 and watch your breakpoint get hit (after giving it some time for copying, remote execution, attachment and symbol resolution to take place).GOING DEEPERIn the MPI Cluster Debugger project properties above, you can see many additional properties to the Run Environment. They are all optional, but you may want to understand them in order to fine tune your cluster debugging. Read all about each one of these on the MSDN page Configuration Properties for the MPI Cluster Debugger.In the Node Selector dialog above you can see more options than just the Head Node name and Number of Process to run. They should be self-explanatory but I also cover them in depth in my screencast showing you an example of why you would choose to schedule processes per core versus per node. You can also read about these options on MSDN as part of the page How to: Configure and Launch the MPI Cluster Debugger.To read through an example that touches on MPI project creation, project properties, node selector, and also usage of MPI with OpenMP plus MPI with PPL, read the MSDN page Walkthrough: Launching the MPI Cluster Debugger in Visual Studio 2010.Happy MPI debugging! Comments about this post welcome at the original blog.
