• Sucky MSTest and the "WaitAll for multiple handles on a STA thread is not supported" Error

  - by Anne Bougie

  If you are doing any multi-threading and are using MSTest, you will probably run across this error. For some reason, MSTest by default runs in STA threading mode. WTF, Microsoft! Why so stuck in the old COM world?  When I run the same test using NUnit, I don't have this problem. Unfortunately, my company has chosen MSTest, so I have a lot of testing problems. NUnit is so much better, IMO. After determining that I wasn't referencing any unmanaged code that would flip the thread into STA, which can also cause this error, the only thing left was the testing suite I was using. I dug around a little and found this obscure setting for the Test Run Config settings file that you can't set using its interface. You have to open it up as a text file and add the following setting:  <ExecutionThread apartmentState="MTA" /> This didn't break any other tests, so I'm not sure why it's not the default, or why there is nothing in the test run configuration app to change this setting. Here is the code I was testing:  public void ProcessTest(ProcessInfo[] infos) {    WaitHandle[] waits = new WaitHandle[infos.Length];    int i = 0;    foreach (ProcessInfo info in infos)    {       AutoResetEvent are = new AutoResetEvent(false);       info.Are = are;       waits[i++] = are;         Processor pr = new Processor();       WaitCallback callback = pr.ProcessTest;       ThreadPool.QueueUserWorkItem(callback, info);    }      WaitHandle.WaitAll(waits); }

• Remastered King’s Quest Games Offer Classic Gaming on Modern Machines

  - by ETC

  If you were a fan of the King’s Quest series of adventure games from the 1980s and 1990s, you’ll be thrilled to see them remastered with enhanced graphics, polished voice acting, and more. Gaming studio AGD Interactive has been engaged in a multi-year project to remaster and freely release the classic King’s Quest games. They started with King’s Quest I in 2001, moved on to King’s Quest II, and just recently released King’s Quest III (see in the screenshot above). The gameplay for all three games is excellent and really captures the feel of the original games (with better graphics, quality voice acting, and adjustments made for modern computers). When you run the game you first get a small pre-launch console. There you can make adjusts to the game before launching it. We’d recommend you enable the pixel doubling filter. It make the game a little blockier (hey you are playing a 1980s remake!) but it fills up high resolution monitors more effectively.

• Platform Builder: PBWorkspaces CESysgen.bat Not Used?

  - by Bruce Eitman

  One of the things that I like about Windows CE is that I am always learning new things, but in this case it is a bit disturbing. We working with Multi UI (MUI) this week and discovered some problems with Windows CE 5.0 and Chinese language support. These problems don’t exist in CE 6.0. The problem was that in the batch files in Public\CEBASE\oak\misc, specifically weceshellfe.bat, some of the shell components needed are only included if certain LOCALs are selected. English is not one of them, I suppose this is because someone didn’t think that we would ever use them and English – doh. No problem, just work around this in PBWorkspaces\<workspace>\WINCE500\<BPS>\cesysgen.bat. But that didn’t work. After a lot of trial and error, what I determined is that this cesysgen.bat isn’t actually used by Platform Builder any more.  Instead, in that same folder is a <workspace>.bat file that is called by Public\CEBASE\oak\misc\cesysgen.bat. That leads to some new problems though, but solvable, in that what I really wanted to do was add a fix after the batch files in CEBASE run, but <workspace>.bat runs before the other batch files in CEBASE. So what I finally came up with was to add the fix to the PASS2 handling in <workspace>.bat. Copyright © 2010 – Bruce Eitman All Rights Reserved

• Introducing Oracle VM VirtualBox

  - by Fat Bloke

  I guess these things always take longer than expected and, while the dust is still not completely settled in all the ex-Sun geographies, it is high time we started looking at some of the great new assets in the Oracle VM portfolio. So let's start with one of the most exciting: Oracle VM VirtualBox. VirtualBox is cross-platform virtualization software, oftentimes called a hypervisor, and it runs on Windows, Linux, Solaris and the Mac. Which means that you download it, you install it on your existing platform, and start creating and running virtual machines alongside your existing applications. For example, on my Mac I can run Oracle Enterprise Linux and Windows 7 alongside my Mac apps like this...(Click to zoom)VirtualBox use has grown phenomenally to the point that at Sun it was the 3rd most popular download behind Java and MySQL. Its success can be attributed to the fact that it doesn't need dedicated hardware, it can be installed on either client or server classes of computers, is very easy to use and is free for personal use. And, as you might expect, VirtualBox has it's own vibrant community too, over at www.virtualbox.org There are hundreds of tutorials out there about how to use VirtualBox to create vm's and install different operating systems ranging from Windows 7 to ChromeOS, and if you don't want to install an operating system yourself, you can download pre-built virtual appliances from community sites such as VirtualBox Images or commercial companies selling subscriptions to whole application stacks, such as JumpBox . In no time you'll be creating and sharing your own vm's using the VirtualBox OVF export and import function. VirtualBox is deceptively powerful. Under the simple GUI lies a formidable engine capable of running heavyweight multi-CPU virtual workloads, exhibiting Enterprise capabilities including a built-in remote display server, an iSCSI initiator for connecting to shared storage, and the ability to teleport running vm's from one host to another. And for solution builders, you should be aware that VirtualBox has a scriptable command line interface and an SDK and rich web service APIs. To get a further feel for what VirtualBox is capable of, check out some of these short movies or simply go download it for yourself.- FB

• Hello Operator, My Switch Is Bored

  - by Paul White

  This is a post for T-SQL Tuesday #43 hosted by my good friend Rob Farley. The topic this month is Plan Operators. I haven’t taken part in T-SQL Tuesday before, but I do like to write about execution plans, so this seemed like a good time to start. This post is in two parts. The first part is primarily an excuse to use a pretty bad play on words in the title of this blog post (if you’re too young to know what a telephone operator or a switchboard is, I hate you). The second part of the post looks at an invisible query plan operator (so to speak). 1. My Switch Is Bored Allow me to present the rare and interesting execution plan operator, Switch: Books Online has this to say about Switch: Following that description, I had a go at producing a Fast Forward Cursor plan that used the TOP operator, but had no luck. That may be due to my lack of skill with cursors, I’m not too sure. The only application of Switch in SQL Server 2012 that I am familiar with requires a local partitioned view: CREATE TABLE dbo.T1 (c1 int NOT NULL CHECK (c1 BETWEEN 00 AND 24)); CREATE TABLE dbo.T2 (c1 int NOT NULL CHECK (c1 BETWEEN 25 AND 49)); CREATE TABLE dbo.T3 (c1 int NOT NULL CHECK (c1 BETWEEN 50 AND 74)); CREATE TABLE dbo.T4 (c1 int NOT NULL CHECK (c1 BETWEEN 75 AND 99)); GO CREATE VIEW V1 AS SELECT c1 FROM dbo.T1 UNION ALL SELECT c1 FROM dbo.T2 UNION ALL SELECT c1 FROM dbo.T3 UNION ALL SELECT c1 FROM dbo.T4; Not only that, but it needs an updatable local partitioned view. We’ll need some primary keys to meet that requirement: ALTER TABLE dbo.T1 ADD CONSTRAINT PK_T1 PRIMARY KEY (c1);   ALTER TABLE dbo.T2 ADD CONSTRAINT PK_T2 PRIMARY KEY (c1);   ALTER TABLE dbo.T3 ADD CONSTRAINT PK_T3 PRIMARY KEY (c1);   ALTER TABLE dbo.T4 ADD CONSTRAINT PK_T4 PRIMARY KEY (c1); We also need an INSERT statement that references the view. Even more specifically, to see a Switch operator, we need to perform a single-row insert (multi-row inserts use a different plan shape): INSERT dbo.V1 (c1) VALUES (1); And now…the execution plan: The Constant Scan manufactures a single row with no columns. The Compute Scalar works out which partition of the view the new value should go in. The Assert checks that the computed partition number is not null (if it is, an error is returned). The Nested Loops Join executes exactly once, with the partition id as an outer reference (correlated parameter). The Switch operator checks the value of the parameter and executes the corresponding input only. If the partition id is 0, the uppermost Clustered Index Insert is executed, adding a row to table T1. If the partition id is 1, the next lower Clustered Index Insert is executed, adding a row to table T2…and so on. In case you were wondering, here’s a query and execution plan for a multi-row insert to the view: INSERT dbo.V1 (c1) VALUES (1), (2); Yuck! An Eager Table Spool and four Filters! I prefer the Switch plan. My guess is that almost all the old strategies that used a Switch operator have been replaced over time, using things like a regular Concatenation Union All combined with Start-Up Filters on its inputs. Other new (relative to the Switch operator) features like table partitioning have specific execution plan support that doesn’t need the Switch operator either. This feels like a bit of a shame, but perhaps it is just nostalgia on my part, it’s hard to know. Please do let me know if you encounter a query that can still use the Switch operator in 2012 – it must be very bored if this is the only possible modern usage! 2. Invisible Plan Operators The second part of this post uses an example based on a question Dave Ballantyne asked using the SQL Sentry Plan Explorer plan upload facility. If you haven’t tried that yet, make sure you’re on the latest version of the (free) Plan Explorer software, and then click the Post to SQLPerformance.com button. That will create a site question with the query plan attached (which can be anonymized if the plan contains sensitive information). Aaron Bertrand and I keep a close eye on questions there, so if you have ever wanted to ask a query plan question of either of us, that’s a good way to do it. The problem The issue I want to talk about revolves around a query issued against a calendar table. The script below creates a simplified version and adds 100 years of per-day information to it: USE tempdb; GO CREATE TABLE dbo.Calendar ( dt date NOT NULL, isWeekday bit NOT NULL, theYear smallint NOT NULL,   CONSTRAINT PK__dbo_Calendar_dt PRIMARY KEY CLUSTERED (dt) ); GO -- Monday is the first day of the week for me SET DATEFIRST 1;   -- Add 100 years of data INSERT dbo.Calendar WITH (TABLOCKX) (dt, isWeekday, theYear) SELECT CA.dt, isWeekday = CASE WHEN DATEPART(WEEKDAY, CA.dt) IN (6, 7) THEN 0 ELSE 1 END, theYear = YEAR(CA.dt) FROM Sandpit.dbo.Numbers AS N CROSS APPLY ( VALUES (DATEADD(DAY, N.n - 1, CONVERT(date, '01 Jan 2000', 113))) ) AS CA (dt) WHERE N.n BETWEEN 1 AND 36525; The following query counts the number of weekend days in 2013: SELECT Days = COUNT_BIG(*) FROM dbo.Calendar AS C WHERE theYear = 2013 AND isWeekday = 0; It returns the correct result (104) using the following execution plan: The query optimizer has managed to estimate the number of rows returned from the table exactly, based purely on the default statistics created separately on the two columns referenced in the query’s WHERE clause. (Well, almost exactly, the unrounded estimate is 104.289 rows.) There is already an invisible operator in this query plan – a Filter operator used to apply the WHERE clause predicates. We can see it by re-running the query with the enormously useful (but undocumented) trace flag 9130 enabled: Now we can see the full picture. The whole table is scanned, returning all 36,525 rows, before the Filter narrows that down to just the 104 we want. Without the trace flag, the Filter is incorporated in the Clustered Index Scan as a residual predicate. It is a little bit more efficient than using a separate operator, but residual predicates are still something you will want to avoid where possible. The estimates are still spot on though: Anyway, looking to improve the performance of this query, Dave added the following filtered index to the Calendar table: CREATE NONCLUSTERED INDEX Weekends ON dbo.Calendar(theYear) WHERE isWeekday = 0; The original query now produces a much more efficient plan: Unfortunately, the estimated number of rows produced by the seek is now wrong (365 instead of 104): What’s going on? The estimate was spot on before we added the index! Explanation You might want to grab a coffee for this bit. Using another trace flag or two (8606 and 8612) we can see that the cardinality estimates were exactly right initially: The highlighted information shows the initial cardinality estimates for the base table (36,525 rows), the result of applying the two relational selects in our WHERE clause (104 rows), and after performing the COUNT_BIG(*) group by aggregate (1 row). All of these are correct, but that was before cost-based optimization got involved :) Cost-based optimization When cost-based optimization starts up, the logical tree above is copied into a structure (the ‘memo’) that has one group per logical operation (roughly speaking). The logical read of the base table (LogOp_Get) ends up in group 7; the two predicates (LogOp_Select) end up in group 8 (with the details of the selections in subgroups 0-6). These two groups still have the correct cardinalities as trace flag 8608 output (initial memo contents) shows: During cost-based optimization, a rule called SelToIdxStrategy runs on group 8. It’s job is to match logical selections to indexable expressions (SARGs). It successfully matches the selections (theYear = 2013, is Weekday = 0) to the filtered index, and writes a new alternative into the memo structure. The new alternative is entered into group 8 as option 1 (option 0 was the original LogOp_Select): The new alternative is to do nothing (PhyOp_NOP = no operation), but to instead follow the new logical instructions listed below the NOP. The LogOp_GetIdx (full read of an index) goes into group 21, and the LogOp_SelectIdx (selection on an index) is placed in group 22, operating on the result of group 21. The definition of the comparison ‘the Year = 2013’ (ScaOp_Comp downwards) was already present in the memo starting at group 2, so no new memo groups are created for that. New Cardinality Estimates The new memo groups require two new cardinality estimates to be derived. First, LogOp_Idx (full read of the index) gets a predicted cardinality of 10,436. This number comes from the filtered index statistics: DBCC SHOW_STATISTICS (Calendar, Weekends) WITH STAT_HEADER; The second new cardinality derivation is for the LogOp_SelectIdx applying the predicate (theYear = 2013). To get a number for this, the cardinality estimator uses statistics for the column ‘theYear’, producing an estimate of 365 rows (there are 365 days in 2013!): DBCC SHOW_STATISTICS (Calendar, theYear) WITH HISTOGRAM; This is where the mistake happens. Cardinality estimation should have used the filtered index statistics here, to get an estimate of 104 rows: DBCC SHOW_STATISTICS (Calendar, Weekends) WITH HISTOGRAM; Unfortunately, the logic has lost sight of the link between the read of the filtered index (LogOp_GetIdx) in group 22, and the selection on that index (LogOp_SelectIdx) that it is deriving a cardinality estimate for, in group 21. The correct cardinality estimate (104 rows) is still present in the memo, attached to group 8, but that group now has a PhyOp_NOP implementation. Skipping over the rest of cost-based optimization (in a belated attempt at brevity) we can see the optimizer’s final output using trace flag 8607: This output shows the (incorrect, but understandable) 365 row estimate for the index range operation, and the correct 104 estimate still attached to its PhyOp_NOP. This tree still has to go through a few post-optimizer rewrites and ‘copy out’ from the memo structure into a tree suitable for the execution engine. One step in this process removes PhyOp_NOP, discarding its 104-row cardinality estimate as it does so. To finish this section on a more positive note, consider what happens if we add an OVER clause to the query aggregate. This isn’t intended to be a ‘fix’ of any sort, I just want to show you that the 104 estimate can survive and be used if later cardinality estimation needs it: SELECT Days = COUNT_BIG(*) OVER () FROM dbo.Calendar AS C WHERE theYear = 2013 AND isWeekday = 0; The estimated execution plan is: Note the 365 estimate at the Index Seek, but the 104 lives again at the Segment! We can imagine the lost predicate ‘isWeekday = 0’ as sitting between the seek and the segment in an invisible Filter operator that drops the estimate from 365 to 104. Even though the NOP group is removed after optimization (so we don’t see it in the execution plan) bear in mind that all cost-based choices were made with the 104-row memo group present, so although things look a bit odd, it shouldn’t affect the optimizer’s plan selection. I should also mention that we can work around the estimation issue by including the index’s filtering columns in the index key: CREATE NONCLUSTERED INDEX Weekends ON dbo.Calendar(theYear, isWeekday) WHERE isWeekday = 0 WITH (DROP_EXISTING = ON); There are some downsides to doing this, including that changes to the isWeekday column may now require Halloween Protection, but that is unlikely to be a big problem for a static calendar table ;)  With the updated index in place, the original query produces an execution plan with the correct cardinality estimation showing at the Index Seek: That’s all for today, remember to let me know about any Switch plans you come across on a modern instance of SQL Server!

• Filling in PDF Forms with ASP.NET and iTextSharp

  The Portable Document Format (PDF) is a popular file format for documents. PDF files are a popular document format for two primary reasons: first, because the PDF standard is an open standard, there are many vendors that provide PDF readers across virtually all operating systems, and many proprietary programs, such as Microsoft Word, include a "Save as PDF" option. Consequently, PDFs server as a sort of common currency of exchange. A person writing a document using Microsoft Word for Windows can save the document as a PDF, which can then be read by others whether or not they are using Windows and whether or not they have Microsoft Word installed. Second, PDF files are self-contained. Each PDF file includes its complete text, fonts, images, input fields, and other content. This means that even complicated documents with many images, an intricate layout, and with user interface elements like textboxes and checkboxes can be encapsulated in a single PDF file. Due to their ubiquity and layout capabilities, it's not uncommon for a websites to use PDF technology. For example, when purchasing goods at an online store you may be offered the ability to download an invoice as a PDF file. PDFs also support form fields, which are user interface elements like textboxes, checkboxes, comboboxes, and the like. These form fields can be entered by a user viewing the PDF or, with a bit of code, they can be entered programmatically. This article is the first in a multi-part series that examines how to programmatically work with PDF files from an ASP.NET application using iTextSharp, a .NET open source library for PDF generation. This installment shows how to use iTextSharp to open an existing PDF document with form fields, fill those form fields with user-supplied values, and then save the combined output to a new PDF file.

• SPARC64 VII+ Processor Core License Factor Reduced by 33%

  - by john.shell

  The Oracle processor core license factor has been a popular topic the last few months.  For those partners new to Oracle software licensing, the processor core license factor determines the number licensed CPUs that are required when running Oracle software (those charged on a per-CPU basis) on multi-core processors.My last entry talked about the core factor reduction for our T3 processor.  The core license factor for our newly announced SPARC64 VII+ processor is 0.5, which is a 33% reduction from the 0.75 rate used with our SPARC64 VI and VII processors.What does this mean for our partners?  Increased opportunity.  This change, similar to our T3-based systems, means that our hardware is the preferred platform for Oracle software. Still a little dizzy on the breadth of Oracle's software offering?  Do a simple scan of Oracle's software price lists. Consider this your target market.This change allows you to focus on total solution price or price/performance, not server prices or per core performance (a standard IBM sales tactic). That's the offensive side of the game.  Don't forget your defense.  One of the biggest customer benefits around the M-Series is investment protection.  The combination of a simple processor/board upgrade, along with a reduction in processor core license factor, makes upgrading one of the best financial moves for our customers.    One reminder.  The update to the processor core license factor only applies to the new VII+ processor - NOT the SPARC64 VI or VII processors.  You can find the official table here.

• Time management and self improvement

  - by Filip

  Hi, I hope I can open a discussion on this topic as this is not a specific problem. It's a topic I hope to get some ideas on how people in similar situation as mine manage their time. OK, I'm a single developer on a software project for the last 6-8 months. The project I'm working on uses several technologies, mainly .net stuff: WPF, WF, NHibernate, WCF, MySql and other third party SDKs relevant for the project nature. My experience and knowledge vary, for example I have a lot of experience in WPF but much less in WCF. I work full time on the project and im curios on how other programmers which need to multi task in many areas manage their time. I'm a very applied type of person and prefer to code instead of doing research. I feel that doing research "might" slow down the progress of the project while I recognize that research and learning more in areas which I'm not so strong will ultimately make me more productive. How would you split up your daily time in productive coding time and time to and experiment, read blogs, go through tutorials etc. I would say that Im coding about 90%+ of my day and devoting some but very little time in research and acquiring new knowledge.

• UPK Professional Customer Success Story: Medtronic

  - by [email protected]

  In case you missed the live event, be sure to listen to last week's UPK Customer iSeminar featuring Medtronic. This was the first iSeminar in our quarterly series to showcase UPK Professional (UPK and Knowledge Pathways). Donna Miller and Staci Gilbert gave viewers an inside look at samples of Medtronic's content as they shared their experiences, methodology and best practices for use of the solution. Here are some highlights of the call: • Medtronic initially purchased UPK Professional to support a multi-year, global SAP rollout for 9,000 end users located in 24 countries. • As time went on, they expanded their use of UPK Professional to include several of their other enterprise applications: PeopleSoft, Siebel CRM, Hyperion Financial Management, a number of SAP bolt-ons, Documentum, TrackWise, and many others. • In combination with their Saba LMS, UPK Professional has allowed Medtronic to create, deploy, track and certify consistent end user training for critical transactions and processes across their organization worldwide - essential for a company in a heavily regulated industry. • For key pieces of content or certain end user populations, some Medtronic business units localize/translate the global UPK content. Staci demonstrated examples of their SAP content which has been translated into Japanese. • In the live SAP environment, end users rely on UPK's context sensitive in-application performance support. Medtronic has found this to be very helpful post go-live, giving just-in-time support so end users are confident in a new system or when performing tasks they don't often touch (at quarter or year end). UPK also serves as Medtronic's internal Google. • Medtronic has realized savings on many fronts: reduction in support calls due to in-application performance support, elimination of their training clients, and speedier training (1.5 days rather than 5-7 days) of temporary workers by moving from ILT to a blended solution that includes UPK simulations for eLearning. Thanks again to Donna and Staci for an exceptional presentation. They offered so many great examples for anyone who's looking for ways to get more out of UPK or interested in learning about UPK Professional: Knowledge Pathways. - Karen Rihs, Oracle UPK Outbound Product Management

• Best Practices for MVC Architecture

  - by Mystere Man

  There are a number of questions on StackOverflow regard MVC best practices, but most of those seem to revolve around things like using Dependancy Injection, or creating helper functions, or do's and don'ts of what to do in views and controllers. My question is more about how to architect an MVC application. For example, we are encouraged to use DI with the Repository pattern to decouple data access from the controller, however very little is said on HOW to do that specifically for MVC. Where would we place the Repository classes, for instance? They don't seem to be model related specifically, since the model should likewise be relatively decoupled from the actual data access technologies. A second question involves how to structure the layers or tiers. Most example applications (Nerd dinner, Music Store, etc..) all seem to use a single tier, 2 layer approach (not counting tests) that typically has controllers directly calling L2S or EF code. If I want to create a multi-tier/layer aplication what are some of the best practices there in regards to MVC? This question is one-part standard q-a, but another part best-practices, so it could go either here or programmers.se, I am marking it CW. If you feel it would be better suited to programmers.se then it can be migrated. EDIT: What happened to the Community Wiki option? It seems to be gone.

• How to Avoid Your Next 12-Month Science Project

  - by constant

  While most customers immediately understand how the magic of Oracle's Hybrid Columnar Compression, intelligent storage servers and flash memory make Exadata uniquely powerful against home-grown database systems, some people think that Exalogic is nothing more than a bunch of x86 servers, a storage appliance and an InfiniBand (IB) network, built into a single rack. After all, isn't this exactly what the High Performance Computing (HPC) world has been doing for decades? On the surface, this may be true. And some people tried exactly that: They tried to put together their own version of Exalogic, but then they discover there's a lot more to building a system than buying hardware and assembling it together. IT is not Ikea. Why is that so? Could it be there's more going on behind the scenes than merely putting together a bunch of servers, a storage array and an InfiniBand network into a rack? Let's explore some of the special sauce that makes Exalogic unique and un-copyable, so you can save yourself from your next 6- to 12-month science project that distracts you from doing real work that adds value to your company. Engineering Systems is Hard Work! The backbone of Exalogic is its InfiniBand network: 4 times better bandwidth than even 10 Gigabit Ethernet, and only about a tenth of its latency. What a potential for increased scalability and throughput across the middleware and database layers! But InfiniBand is a beast that needs to be tamed: It is true that Exalogic uses a standard, open-source Open Fabrics Enterprise Distribution (OFED) InfiniBand driver stack. Unfortunately, this software has been developed by the HPC community with fastest speed in mind (which is good) but, despite the name, not many other enterprise-class requirements are included (which is less good). Here are some of the improvements that Oracle's InfiniBand development team had to add to the OFED stack to make it enterprise-ready, simply because typical HPC users didn't have the need to implement them: More than 100 bug fixes in the pieces that were not related to the Message Passing Interface Protocol (MPI), which is the protocol that HPC users use most of the time, but which is less useful in the enterprise. Performance optimizations and tuning across the whole IB stack: From Switches, Host Channel Adapters (HCAs) and drivers to low-level protocols, middleware and applications. Yes, even the standard HPC IB stack could be improved in terms of performance. Ethernet over IB (EoIB): Exalogic uses InfiniBand internally to reach high performance, but it needs to play nicely with datacenters around it. That's why Oracle added Ethernet over InfiniBand technology to it that allows for creating many virtual 10GBE adapters inside Exalogic's nodes that are aggregated and connected to Exalogic's IB gateway switches. While this is an open standard, it's up to the vendor to implement it. In this case, Oracle integrated the EoIB stack with Oracle's own IB to 10GBE gateway switches, and made it fully virtualized from the beginning. This means that Exalogic customers can completely rewire their server infrastructure inside the rack without having to physically pull or plug a single cable - a must-have for every cloud deployment. Anybody who wants to match this level of integration would need to add an InfiniBand switch development team to their project. Or just buy Oracle's gateway switches, which are conveniently shipped with a whole server infrastructure attached! IPv6 support for InfiniBand's Sockets Direct Protocol (SDP), Reliable Datagram Sockets (RDS), TCP/IP over IB (IPoIB) and EoIB protocols. Because no IPv6 = not very enterprise-class. HA capability for SDP. High Availability is not a big requirement for HPC, but for enterprise-class application servers it is. Every node in Exalogic's InfiniBand network is connected twice for redundancy. If any cable or port or HCA fails, there's always a replacement link ready to take over. This requires extra magic at the protocol level to work. So in addition to Weblogic's failover capabilities, Oracle implemented IB automatic path migration at the SDP level to avoid unnecessary failover operations at the middleware level. Security, for example spoof-protection. Another feature that is less important for traditional users of InfiniBand, but very important for enterprise customers. InfiniBand Partitioning and Quality-of-Service (QoS): One of the first questions we get from customers about Exalogic is: “How can we implement multi-tenancy?” The answer is to partition your IB network, which effectively creates many networks that work independently and that are protected at the lowest networking layer possible. In addition to that, QoS allows administrators to prioritize traffic flow in multi-tenancy environments so they can keep their service levels where it matters most. Resilient IB Fabric Management: InfiniBand is a self-managing network, so a lot of the magic lies in coming up with the right topology and in teaching the subnet manager how to properly discover and manage the network. Oracle's Infiniband switches come with pre-integrated, highly available fabric management with seamless integration into Oracle Enterprise Manager Ops Center. In short: Oracle elevated the OFED InfiniBand stack into an enterprise-class networking infrastructure. Many years and multiple teams of manpower went into the above improvements - this is something you can only get from Oracle, because no other InfiniBand vendor can give you these features across the whole stack! Exabus: Because it's not About the Size of Your Network, it's How You Use it! So let's assume that you somehow were able to get your hands on an enterprise-class IB driver stack. Or maybe you don't care and are just happy with the standard OFED one? Anyway, the next step is to actually leverage that InfiniBand performance. Here are the choices: Use traditional TCP/IP on top of the InfiniBand stack, Develop your own integration between your middleware and the lower-level (but faster) InfiniBand protocols. While more bandwidth is always a good thing, it's actually the low latency that enables superior performance for your applications when running on any networking infrastructure: The lower the latency, the faster the response travels through the network and the more transactions you can close per second. The reason why InfiniBand is such a low latency technology is that it gets rid of most if not all of your traditional networking protocol stack: Data is literally beamed from one region of RAM in one server into another region of RAM in another server with no kernel/drivers/UDP/TCP or other networking stack overhead involved! Which makes option 1 a no-go: Adding TCP/IP on top of InfiniBand is like adding training wheels to your racing bike. It may be ok in the beginning and for development, but it's not quite the performance IB was meant to deliver. Which only leaves option 2: Integrating your middleware with fast, low-level InfiniBand protocols. And this is what Exalogic's "Exabus" technology is all about. Here are a few Exabus features that help applications leverage the performance of InfiniBand in Exalogic: RDMA and SDP integration at the JDBC driver level (SDP), for Oracle Weblogic (SDP), Oracle Coherence (RDMA), Oracle Tuxedo (RDMA) and the new Oracle Traffic Director (RDMA) on Exalogic. Using these protocols, middleware can communicate a lot faster with each other and the Oracle database than by using standard networking protocols, Seamless Integration of Ethernet over InfiniBand from Exalogic's Gateway switches into the OS, Oracle Weblogic optimizations for handling massive amounts of parallel transactions. Because if you have an 8-lane Autobahn, you also need to improve your ramps so you can feed it with many cars in parallel. Integration of Weblogic with Oracle Exadata for faster performance, optimized session management and failover. As you see, “Exabus” is Oracle's word for describing all the InfiniBand enhancements Oracle put into Exalogic: OFED stack enhancements, protocols for faster IB access, and InfiniBand support and optimizations at the virtualization and middleware level. All working together to deliver the full potential of InfiniBand performance. Who else has 100% control over their middleware so they can develop their own low-level protocol integration with InfiniBand? Even if you take an open source approach, you're looking at years of development work to create, test and support a whole new networking technology in your middleware! The Extras: Less Hassle, More Productivity, Faster Time to Market And then there are the other advantages of Engineered Systems that are true for Exalogic the same as they are for every other Engineered System: One simple purchasing process: No headaches due to endless RFPs and no “Will X work with Y?” uncertainties. Everything has been engineered together: All kinds of bugs and problems have been already fixed at the design level that would have only manifested themselves after you have built the system from scratch. Everything is built, tested and integrated at the factory level . Less integration pain for you, faster time to market. Every Exalogic machine world-wide is identical to Oracle's own machines in the lab: Instant replication of any problems you may encounter, faster time to resolution. Simplified patching, management and operations. One throat to choke: Imagine finger-pointing hell for systems that have been put together using several different vendors. Oracle's Engineered Systems have a single phone number that customers can call to get their problems solved. For more business-centric values, read The Business Value of Engineered Systems. Conclusion: Buy Exalogic, or get ready for a 6-12 Month Science Project And here's the reason why it's not easy to "build your own Exalogic": There's a lot of work required to make such a system fly. In fact, anybody who is starting to "just put together a bunch of servers and an InfiniBand network" is really looking at a 6-12 month science project. And the outcome is likely to not be very enterprise-class. And it won't have Exalogic's performance either. Because building an Engineered System is literally rocket science: It takes a lot of time, effort, resources and many iterations of design/test/analyze/fix to build such a system. That's why InfiniBand has been reserved for HPC scientists for such a long time. And only Oracle can bring the power of InfiniBand in an enterprise-class, ready-to use, pre-integrated version to customers, without the develop/integrate/support pain. For more details, check the new Exalogic overview white paper which was updated only recently.

• Using progress dialog in Visual Studio extensions

  - by Utkarsh Shigihalli

  Originally posted on: http://geekswithblogs.net/onlyutkarsh/archive/2014/05/23/using-progress-dialog-in-visual-studio-extensions.aspxAs a Visual Studio extension developer you are required to keep the aesthetics of Visual Studio in tact when you integrate your extension with Visual Studio. Your extension looks odd when you try to use windows controls and dialogs in your extensions. Visual Studio SDK exposes many interfaces so that your extension looks as integrated with Visual Studio as possible. When your extension is performing a long running task, you have many options to notify the progress to the user. One such option is through Visual Studio status bar. I have previously blogged about displaying progress through Visual Studio status bar. In this blog post I am going to highlight another way using IVsThreadedWaitDialog2 interface. One thing to note is, as the IVsThreadedWaitDialog2 interface name suggests it is a dialog hence user cannot perform any action when the dialog is being shown. So Visual Studio seems responsive to user, even when a task is being performed. Visual Studio itself makes use of this interface heavily. One example is when you are loading a solution (.sln) with lot of projects Visual Studio displays dialog implemented by this interface (screenshot below). So the first step is to get the instance of IVsThreadedWaitDialog2 interface using IServiceProvider interface. var dialogFactory = _serviceProvider.GetService(typeof(SVsThreadedWaitDialogFactory)) as IVsThreadedWaitDialogFactory; IVsThreadedWaitDialog2 dialog = null; if (dialogFactory != null) { dialogFactory.CreateInstance(out dialog); } So if your have the package initialized properly out object dialog will be not null and would contain the instance of IVsThreadedWaitDialog2 interface. Once the instance is got, you call the different methods to manage the dialog. I will cover 3 methods StartWaitDialog, EndWaitDialog and HasCanceled in this blog post. You show the progress dialog as below. if (dialog != null && dialog.StartWaitDialog( "Threaded Wait Dialog", "VS is Busy", "Progress text", null, "Waiting status bar text", 0, false, true) == VSConstants.S_OK) { Thread.Sleep(4000); } As you can see from the method syntax it is very similar to standard windows message box. If you pass true to the 7th parameter to StartWaitDialog method, you will also see a cancel button allowing user to cancel the running task. You can react when user cancels the task as below. bool isCancelled; dialog.HasCanceled(out isCancelled); if (isCancelled) { MessageBox.Show("Cancelled"); } Finally, you can close the dialog when you complete the task running as below. int usercancel; dialog.EndWaitDialog(out usercancel); To help you quickly experience the above code, I have created a sample. It is available for download from GitHub. The sample creates a tool window with two buttons to demo the above explained scenarios. The tool window can be accessed by clicking View –> Other Windows -> ProgressDialogDemo Window

• PASS 13 Dispatches: Memory Optimized = On

  - by Tony Davis

  I'm at the PASS Summit in Charlotte for the Day 1 keynote by Quentin Clarke, Corporate VP of the data platform group at Microsoft. He's talking about how SQL Server 2014 is “pushing boundaries” and first up is SQL Server 2014's In-Memory OLTP technology (former codename “hekaton”) It is a feature that provokes a lot of interest and for good reason as, without any need for application rewrites or hardware updates, it can enable us to ensure that an application can find in memory most or all of the data it needs, and can lead to huge improvements in processing times. A good recent hekaton use cases article talks about applications that need a “Shock Absorber” when either spikes or just a high rate of incoming workload (including data in ETL scenarios) become a primary bottleneck. To get a really deep look at this technology, I would check out David DeWitt's summit keynote tomorrow (it will be live streamed). Other than that, to get started I'd recommend Kalen Delaney's whitepaper. She offers a lot of insight into how it works and how to start to define memory-optimized tables, and natively compiled stored procedures. These memory-optimized tables uses completely optimistic multi-version concurrency control – no waiting on locks! After that, Tom LaRock has compiled a useful set of links to drill deeper, and includes one to Microsoft's AMR tool to help you gauge the tables that might benefit most. Tony.

• Accessing Server-Side Data from Client Script: Accessing JSON Data From an ASP.NET Page Using jQuery

  When building a web application, we must decide how and when the browser will communicate with the web server. The ASP.NET WebForms model greatly simplifies web development by providing a straightforward mechanism for exchanging data between the browser and the server. With WebForms, each ASP.NET page's rendered output includes a <form> element that performs a postback to the same page whenever a Button control within the form is clicked, or whenever the user modifies a control whose AutoPostBack property is set to True. On postback, the server sends the entire contents of the web page back to the browser, which then displays this new content. With WebForms we don't need to spend much time or effort thinking about how or when the browser will communicate with the server or how that returned information will be processed by the browser. It just works. While this approach certainly works and has its advantages, it's not without its drawbacks. The primary concern with postback forms is that they require a large amount of information to be exchanged between the browser and the server. Specifically, the browser sends back all of its form fields (including hidden ones, like view state, which may be quite large) and then the server sends back the entire contents of the web page. Granted, there are scenarios where this large quantity of data needs to be exchanged, but in many cases we can use techniques that exchange much less information. However, these techniques necessitate spending more time and effort thinking about how and when to have the browser communicate with the server and intelligently deciding on what information needs to be exchanged. This article, the first in a multi-part series, examines different techniques for accessing server-side data from a browser using client-side script. Throughout this series we will explore alternative ways to expose data on the server so that it can be accessed from the browser using script; we will also examine various tools for communicating with the server from JavaScript, including jQuery and the ASP.NET AJAX library.

• Time management and self improvement

  - by Filip

  I hope I can open a discussion on this topic as this is not a specific problem. It's a topic I hope to get some ideas on how people in similar situation as mine manage their time. OK, I'm a single developer on a software project for the last 6-8 months. The project I'm working on uses several technologies, mainly .net stuff: WPF, WF, NHibernate, WCF, MySql and other third party SDKs relevant for the project nature. My experience and knowledge vary, for example I have a lot of experience in WPF but much less in WCF. I work full time on the project and im curios on how other programmers which need to multi task in many areas manage their time. I'm a very applied type of person and prefer to code instead of doing research. I feel that doing research "might" slow down the progress of the project while I recognize that research and learning more in areas which I'm not so strong will ultimately make me more productive. How would you split up your daily time in productive coding time and time to and experiment, read blogs, go through tutorials etc. I would say that Im coding about 90%+ of my day and devoting some but very little time in research and acquiring new knowledge. Thanks for your replies. I think I will adopt a gradual transition to Dominics block parts. I kinda knew that coding was taking up way to much of my time but it feels good having a first version of the project completed and ready. With a few months of focused hard work behind me I hope to get more time to experiment and expand my knowlegde. Now I only hope my boss will cut me some slack and stop pressuring me for features...

• Keyboard locking up in Visual Studio 2010

  - by Jim Wang

  One of the initiatives I’m involved with on the ASP.NET and Visual Studio teams is the Tactical Test Team (TTT), which is a group of testers who dedicate a portion of their time to roaming around and testing different parts of the product.  What this generally translates to is a day and a bit a week helping out with areas of the product that have been flagged as risky, or tackling problems that span both ASP.NET and Visual Studio.  There is also a separate component of this effort outside of TTT which is to help with customer scenarios and design. I enjoy being on TTT because it allows me the opportunity to look at the entire product and gain expertise in a wide range of areas.  This week, I’m looking at Visual Studio 2010 performance problems, and this gem with the keyboard in Visual Studio locking up ended up catching my attention. First of all, here’s a link to one of the many Connect bugs describing the problem: Microsoft Connect I like this problem because it really highlights the challenges of reproducing customer bugs.  There aren’t any clear steps provided here, and I don’t know a lot about your environment: not just the basics like our OS version, but also what third party plug-ins or antivirus software you might be running that might contribute to the problem.  In this case, my gut tells me that there is more than one bug here, just by the sheer volume of reports.  Here’s another thread where users talk about it: Microsoft Connect The volume and different configurations are staggering.  From a customer perspective, this is a very clear cut case of basic functionality not working in the product, but from our perspective, it’s hard to find something reproducible: even customers don’t quite agree on what causes the problem (installing ReSharper seems to cause a problem…or does it?). So this then, is the start of a QA investigation. If anybody has isolated repro steps (just comment on this post) that they can provide this will immensely help us nail down the issue(s), but I’ll be doing a multi-part series on my progress and methodologies as I look into the problem.

• Order Unlocked iPhone 4S From Apple Online Store. $649, No Contract, Any Network.
