• What is a proper way to store site-level global variables in a SharePoint site?

  - by ccomet

  One thing that has driven me nuts about SharePoint2007 is the apparent inability to have defineable settings that apply specifically to a site or site collection itself, and not the content. I mean, you have some pre-defined settings like the Site Logo, the Site Name, and various other things, but there doesn't appear to be anywhere to add new kinds of settings. The application I am working on needs to be able to create multiple kinds of "project site collections" that all follow a basic template, but have certain additional settings that apply specifically to that site collection and that one alone. In addition to the standard site name we also need to define the Project Number, the Project Name, and the Client Name. And given the requests of some of our clients, we also reach a point where we have to have configurable settings that alter how some of the workflows work, like whether files are marked with Letters or Numbers. Our current solution, which I'm hesitant about, has been to store an XML file on the SharePoint server. This file contains one node for each site collection, identified by the URL of the root site. Inside the node are all of the elements that need to be defined for that site collection. When we need them, we have to access the XML file (which will always require SPSecurity.RunWithElevatedPrivileges to access files right on the server) every time to load it and retrieve the data. There are a lot of automated processes which will have to do this, and I'm hesitant about the stability of this method when we reach hundreds of sites with thousands of files running tens of thousands of workflows, all wanting to access this file. Maybe they're unfounded worries, but I'd rather worry than risk everything breaking in a couple years. I was looking into the SPWeb object and found the AllProperties hashtable. It looks like just the kind of thing which might work, but I don't know how safe it is to be modifying this. I read through both MSDN and the WSS SDK but found nothing that clarified on adding completely new properties into AllProperties. Is it safe to use AllProperties for this kind of thing? Or is there yet another feature that I am missing, which could handle the concept of global variables at the site collection or site scope?

• How to select all parent objects into DataContext using single LINQ query ?

  - by too

  I am looking for an answer to a specific problem of fetching whole LINQ object hierarchy using single SELECT. At first I was trying to fill as much LINQ objects as possible using LoadOptions, but AFAIK this method allows only single table to be linked in one query using LoadWith. So I have invented a solution to forcibly set all parent objects of entity which of list is to be fetched, although there is a problem of multiple SELECTS going to database - a single query results in two SELECTS with the same parameters in the same LINQ context. For this question I have simplified this query to popular invoice example: public static class Extensions { public static IEnumerable<T> ForEach<T>(this IEnumerable<T> collection, Action<T> func) { foreach(var c in collection) { func(c); } return collection; } } public IEnumerable<Entry> GetResults(AppDataContext context, int CustomerId) { return ( from entry in context.Entries join invoice in context.Invoices on entry.EntryInvoiceId equals invoice.InvoiceId join period in context.Periods on invoice.InvoicePeriodId equals period.PeriodId // LEFT OUTER JOIN, store is not mandatory join store in context.Stores on entry.EntryStoreId equals store.StoreId into condStore from store in condStore.DefaultIfEmpty() where (invoice.InvoiceCustomerId = CustomerId) orderby entry.EntryPrice descending select new { Entry = entry, Invoice = invoice, Period = period, Store = store } ).ForEach(x => { x.Entry.Invoice = Invoice; x.Invoice.Period = Period; x.Entry.Store = Store; } ).Select(x => x.Entry); } When calling this function and traversing through result set, for example: var entries = GetResults(this.Context); int withoutStore = 0; foreach(var k in entries) { if(k.EntryStoreId == null) withoutStore++; } the resulting query to database looks like (single result is fetched): SELECT [t0].[EntryId], [t0].[EntryInvoiceId], [t0].[EntryStoreId], [t0].[EntryProductId], [t0].[EntryQuantity], [t0].[EntryPrice], [t1].[InvoiceId], [t1].[InvoiceCustomerId], [t1].[InvoiceDate], [t1].[InvoicePeriodId], [t2].[PeriodId], [t2].[PeriodName], [t2].[PeriodDateFrom], [t4].[StoreId], [t4].[StoreName] FROM [Entry] AS [t0] INNER JOIN [Invoice] AS [t1] ON [t0].[EntryInvoiceId] = [t1].[InvoiceId] INNER JOIN [Period] AS [t2] ON [t2].[PeriodId] = [t1].[InvoicePeriodId] LEFT OUTER JOIN ( SELECT 1 AS [test], [t3].[StoreId], [t3].[StoreName] FROM [Store] AS [t3] ) AS [t4] ON [t4].[StoreId] = ([t0].[EntryStoreId]) WHERE (([t1].[InvoiceCustomerId]) = @p0) ORDER BY [t0].[InvoicePrice] DESC -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [186] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1 SELECT [t0].[EntryId], [t0].[EntryInvoiceId], [t0].[EntryStoreId], [t0].[EntryProductId], [t0].[EntryQuantity], [t0].[EntryPrice], [t1].[InvoiceId], [t1].[InvoiceCustomerId], [t1].[InvoiceDate], [t1].[InvoicePeriodId], [t2].[PeriodId], [t2].[PeriodName], [t2].[PeriodDateFrom], [t4].[StoreId], [t4].[StoreName] FROM [Entry] AS [t0] INNER JOIN [Invoice] AS [t1] ON [t0].[EntryInvoiceId] = [t1].[InvoiceId] INNER JOIN [Period] AS [t2] ON [t2].[PeriodId] = [t1].[InvoicePeriodId] LEFT OUTER JOIN ( SELECT 1 AS [test], [t3].[StoreId], [t3].[StoreName] FROM [Store] AS [t3] ) AS [t4] ON [t4].[StoreId] = ([t0].[EntryStoreId]) WHERE (([t1].[InvoiceCustomerId]) = @p0) ORDER BY [t0].[InvoicePrice] DESC -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [186] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1 The question is why there are two queries and how can I fetch LINQ objects without such hacks?

• NHibernate Session Load vs Get when using Table per Hierarchy. Always use ISession.Get&lt;T&gt; for TPH to work.

  - by Rohit Gupta

  Originally posted on: http://geekswithblogs.net/rgupta/archive/2014/06/01/nhibernate-session-load-vs-get-when-using-table-per-hierarchy.aspxNHibernate ISession has two methods on it : Load and Get. Load allows the entity to be loaded lazily, meaning the actual call to the database is made only when properties on the entity being loaded is first accessed. Additionally, if the entity has already been loaded into NHibernate Cache, then the entity is loaded directly from the cache instead of querying the underlying database. ISession.Get<T> instead makes the call to the database, every time it is invoked. With this background, it is obvious that we would prefer ISession.Load<T> over ISession.Get<T> most of the times for performance reasons to avoid making the expensive call to the database. let us consider the impact of using ISession.Load<T> when we are using the Table per Hierarchy implementation of NHibernate. Thus we have base class/ table Animal, there is a derived class named Snake with the Discriminator column being Type which in this case is “Snake”. If we load This Snake entity using the Repository for Animal, we would have a entity loaded, as shown below: public T GetByKey(object key, bool lazy = false) { if (lazy) return CurrentSession.Load<T>(key); return CurrentSession.Get<T>(key); } var tRepo = new NHibernateReadWriteRepository<TPHAnimal>(); var animal = tRepo.GetByKey(new Guid("602DAB56-D1BD-4ECC-B4BB-1C14BF87F47B"), true); var snake = animal as Snake; snake is null As you can see that the animal entity retrieved from the database cannot be cast to Snake even though the entity is actually a snake. The reason being ISession.Load prevents the entity to be cast to Snake and will throw the following exception: System.InvalidCastException :  Message=Unable to cast object of type 'TPHAnimalProxy' to type 'NHibernateChecker.Model.Snake'. Thus we can see that if we lazy load the entity using ISession.Load<TPHAnimal> then we get a TPHAnimalProxy and not a snake. =============================================================== However if do not lazy load the same cast works perfectly fine, this is since we are loading the entity from database and the entity being loaded is not a proxy. Thus the following code does not throw any exceptions, infact the snake variable is not null: var tRepo = new NHibernateReadWriteRepository<TPHAnimal>(); var animal = tRepo.GetByKey(new Guid("602DAB56-D1BD-4ECC-B4BB-1C14BF87F47B"), false); var snake = animal as Snake; if (snake == null) { var snake22 = (Snake) animal; }

• PASS Summit for SQL Starters

  - by Davide Mauri

  I’ve received a buch of emails from PASS Summit “First Timers” that are also somehow new to SQL Server (for “somehow” I mean people with less than 6 month experience but with some basic knowledge of SQL Server engine) or are catching up from SQL Server 2000. The common question regards the session one should not miss to have a broad view of the entire SQL Server platform have some insight into some specific areas of SQL Server Given that I’m on (semi-)vacantion and that I have more free time (not true, I have to prepare slides & demos for several conferences, PASS Summit  - Building the Agile Data Warehouse with SQL Server 2012 - and PASS 24H - Agile Data Warehousing with SQL Server 2012 - among them…but let’s pretend it to be true), I’ve decided to make a post to answer to this common questions. Of course this is my personal point of view and given the fact that the number and quality of session that will be delivered at PASS Summit is so high that is very difficoult to make a choice, fell free to jump into the discussion and leave your feedback or – even better – answer with another post. I’m sure it will be very helpful to all the SQL Server beginners out there. I’ve imposed to myself to choose 6 session at maximum for each Track. Why 6? Because it’s the maximum number of session you can follow in one day, and given that all the session will be on the Summit DVD, they are the answer to the following question: “If I have one day to spend in training, which session I should watch?”. Of course a Summit is not like a Course so a lot of very basics concept of well-established technologies won’t be found here. Analysis Services, Integration Services, MDX are not part of the Summit this time (at least for the basic part of them). Enough with that, let’s start with the session list ideal to have a good Overview of all the SQL Server Platform: Geospatial Data Types in SQL Server 2012 Inside Unstructured Data: SQL Server 2012 FileTable and Semantic Search XQuery and XML in SQL Server: Common Problems and Best Practice Solutions Microsoft's Big Play for Big Data Dashboards: When to Choose Which MSBI Tool Microsoft BI End-User Tools 360° for what concern Database Development, I recommend the following sessions Understanding Transaction Isolation Levels What to Look for in Execution Plans Improve Query Performance by Fixing Bad Parameter Sniffing A Window into Your Data: Using SQL Window Functions Practical Uses and Optimization of New T-SQL Features in SQL Server 2012 Taking MERGE Beyond the Basics For Business Intelligence Information Delivery Analyzing SSAS Data with Excel Building Compelling Power View Reports Managed Self-Service BI PowerPivot 101  SharePoint for Business Intelligence The Best Microsoft BI Tools You've Never Heard Of and for Business Intelligence Architecture & Development BI Power Hour Building a Tabular Model Database Enterprise Information Management: Bringing Together SSIS, DQS, and MDS SSIS Design Patterns Storing Columnstore Indexes Hadoop and Its Ecosystem Components in Action Beside the listed sessions, First Timers should also take a look the the page PASS set up for them: http://www.sqlpass.org/summit/2012/Connect/FirstTimers.aspx See you at PASS Summit!

• html5 uploader + jquery drag & drop: how to store file data with FormData?

  - by lauthiamkok

  I am making a html5 drag and drop uploader with jquery, below is my code so far, the problem is that I get an empty array without any data. Is this line incorrect to store the file data - fd.append('file', $thisfile);? $('#div').on( 'dragover', function(e) { e.preventDefault(); e.stopPropagation(); } ); $('#div').on( 'dragenter', function(e) { e.preventDefault(); e.stopPropagation(); } ); $('#div').on( 'drop', function(e){ if(e.originalEvent.dataTransfer){ if(e.originalEvent.dataTransfer.files.length) { e.preventDefault(); e.stopPropagation(); // The file list. var fileList = e.originalEvent.dataTransfer.files; //console.log(fileList); // Loop the ajax post. for (var i = 0; i < fileList.length; i++) { var $thisfile = fileList[i]; console.log($thisfile); // HTML5 form data object. var fd = new FormData(); //console.log(fd); fd.append('file', $thisfile); /* var file = {name: fileList[i].name, type: fileList[i].type, size:fileList[i].size}; $.each(file, function(key, value) { fd.append('file['+key+']', value); }) */ $.ajax({ url: "upload.php", type: "POST", data: fd, processData: false, contentType: false, success: function(response) { // .. do something }, error: function(jqXHR, textStatus, errorMessage) { console.log(errorMessage); // Optional } }); } /*UPLOAD FILES HERE*/ upload(e.originalEvent.dataTransfer.files); } } } ); function upload(files){ console.log('Upload '+files.length+' File(s).'); }; then if I use another method is that to make the file data into an array inside the jquery code, var file = {name: fileList[i].name, type: fileList[i].type, size:fileList[i].size}; $.each(file, function(key, value) { fd.append('file['+key+']', value); }); but where is the tmp_name data inside e.originalEvent.dataTransfer.files[i]? php, print_r($_POST); $uploaddir = './uploads/'; $file = $uploaddir . basename($_POST['file']['name']); if (move_uploaded_file($_POST['file']['tmp_name'], $file)) { echo "success"; } else { echo "error"; } as you can see that tmp_name is needed to upload the file via php... html, <div id="div">Drop here</div>

• Determining whether a visitor reached two different pages in one visit

  - by Shaun

  I have a funnel that I would like to track. Tracking this funnel won't work with the default "goal funnel" tracking in Google due to the fact that I am mixing events and pageviews. As such, I've created a series of reports: Visits to demo pages - An inclusion filter on "Page". Triggers an Event on these pages - An inclusion filter on "Page" and "Event Category". Does not bounce - An inclusion filter on "Page" and an exclusion filter on "Exit Page" for these same pages. Reach our storefront - ?? Purchase something - An inclusion filter on "Page" and a report that shows "Transactions". At a basic level, I need to track users who reached demo pages, then reached any page on our store. Intuitively, I created a segment, used two inclusive "Page" filters (one for the demo pages and one for any page in our store), and combined them with an "AND" operator. I thought this was working until I tried to do the same thing in a dashboard widget and on a custom report. When I tried the same thing in those areas, I got zero results. I figured this might be because widgets and custom report filters function differently from segment filters (the options are different for all of them), so I tried applying my "demo page && store page" segment to a report that gave me a general page list. All I saw was a list of the specific pages. I tried simplifying things by creating a custom report that showed all visits to store pages, then applied a segment that filtered for users who visited demo pages. This got me the same numbers as my "demo page && store page" segment, but showed a list of demo pages. This has led me to believe that the "demo page && store page segment" approach and the "demo segment && store report" functionally behave the same. However, this experience has left me questioning whether they're giving me what I want. Are these methods showing me all users who reached both sets of pages? Is there a better/easier/more standard way of doing this aside from looking at visitor flow reports? I'm trying to avoid a combination of custom variables/events and using the horizontal funnel approach since it would consume a large number of our limited goals and seems more complicated than is necessary for tracking this funnel.

• Using jQuery to store basic text string in mySQL base?

  - by Kenny Bones

  Could someone point me in the right direction here? Basically, I've got this jQuery code snippet: $('.bggallery_images').click(function () { var newBG = "url('" + $(this).attr('src'); var fullpath = $(this).attr('src'); var filename = fullpath.replace('img/Bakgrunner/', ''); $('#wrapper').css('background-image', newBG); // Lagre til SQL $.ajax({ url: "save_to_db.php", // The url to your function to handle saving to the db data: filename, dataType: 'Text', type: 'POST', // Could also use GET if you prefer success: function (data) { // Just for testing purposes. alert('Background changed to: ' + data); } }); }); This is being run when I click a certain button. So it's actually within a click handler. If I understand this correctly, this snippet takes the source if the image I just clicked and strips it so I end up with only the filename. If I do an alert(filename), I get the filename only. So this is working ok. But then, it does an ajax call to a php file called "save_to_db.php" and sends data: filename. This is correct right? Then, it does a callback which does an alert + data. Does this seem correct so far? Cause my php file looks like this: <?php require("dbconnect2.php"); $uploadstring = $_POST['filename']; $sessionid = $_SESSION['id']; echo ($sessionid); mysql_query("UPDATE brukere SET brukerBakgrunn = '$uploadstring' WHERE brukerID=" .$_SESSION['id']); mysql_close(); ?> When I click the image, the jQuery snippet fires and I get the results of this php file as output for the alert box. I think that the variables somehow are empty. Because notice the echo($sessionid); which is a variable I've created just to test what the session ID is. And it returns nothing. What could be the issue here? Edit: I just tried to echo out the $uploadstring variable as well and it also returns nothing. It's like the jQuery snippet doesn't even pass the variable on to the php file?

• How to store multiple scroll positions for scrolling div element depending on active View in MultiView (asp.net webform

  - by Spence

  confusing title but the best way I can put it. Basically I am currently using a single div with overflow:auto that contains different GridViews. The GridViews are swapped by using a MultiView with each indiviudal view containing a single GridView. I would like to be able to store the scroll position of each view so that I can set the div's scroll position depending on the view that will be switched to. Here is how my page is set up. <div id="scrollingDiv" style="height:100%; overflow:auto;"> <div id="gridWrap"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" RenderMode="Inline"> <ContentTemplate> <asp:MultiView ID="MultiView1" runat="server"> <asp:View ID="view1" runat="server"> <asp:GridView ID="gridView1" runat="server"> </asp:GridView> </asp:View> <asp:View ID="view2" runat="server"> <asp:GridView ID="gridView2" runat="server"> </asp:GridView> </asp:View> </asp:Multiview> </ContentTemplate> </asp:UpdatePanel> </div> </div> So scrollingDiv will contain all the Views and will scroll for each one of the GridViews. To switch between views I have a drop down connected to an protected void DropDownList_SelectedIndexChanged(object sender, EventArgs e) { switch (DownList.SelectedItem.Value) { case "view1": MultiView1.SetActiveView(view1); break; case "view2": MultiView1.SetActiveView(view2); break; } } I have been looking around and can't quite find something specific to my case. I would like to be able to use just the one overflow div but would understand if I had to make a separate overflow div for each view. Any help would be great, Thanks.

• What is the best approach in SQL to store multi-level descriptions?

  - by gime

  I need a new perspective on how to design a reliable and efficient SQL database to store multi-level arrays of data. This problem applies to many situations but I came up with this example: There are hundreds of products. Each product has an undefined number of parts. Each part is built from several elements. All products are described in the same way. All parts would require the same fields to describe them (let's say: price, weight, part name), all elements of all parts also have uniform design (for example: element code, manufacturer). Plain and simple. One element may be related to only part, and each part is related to one product only. I came up with idea of three tables: Products: -------------------------------------------- prod_id prod_name prod_price prod_desc 1 hoover 120 unused next Parts: ---------------------------------------------------- part_id part_name part_price part_weight prod_id 3 engine 10 20 1 and finally Elements: --------------------------------------- el_id el_code el_manufacturer part_id 1 BFG12 GE 3 Now, select a desired product, select all from PARTS where prod_id is the same, and then select all from ELEMENTS where part_id matches - after multiple queries you've got all data. I'm just not sure if this is the right approach. I've got also another idea, without ELEMENTS table. That would decrease queries but I'm a bit afraid it might be lame and bad practice. Instead of ELEMENTS table there are two more fields in the PARTS table, so it looks like this: part_id, part_name, part_price, part_weight, prod_id, part_el_code, part_el_manufacturer they would be text type, and for each part, information about elements would be stored as strings, this way: part_el_code | code_of_element1; code_of_element2; code_of_element3 part_el_manufacturer | manuf_of_element1; manuf_of_element2; manuf_of_element3 Then all we need is to explode() data from those fields, and we get arrays, easy to display. Of course this is not perfect and has some limitations, but is this idea ok? Or should I just go with the first idea? Or maybe there is a better approach to this problem? It's really hard to describe it in few words, and that means it's hard to search for answer. Also, understanding the principles of designing databases is not that easy as it seems.

• Chrome is creating duplicate sessions with the same id

  - by dlwiest

  I encountered an issue while I was revising my session library today, and this might be the first time I've ever seen a browser-specific problem on a back end script. I hope somebody can shed some light. Basically how the session library works is: when instantiated, it checks for a cookie called 'id' (in the form of a uniqid result) on the client machine. If a cookie is found, the script checks that and a hashed copy of the user agent string against entries in a session table. If a matching entry is found, the script resumes the session. If no cookie named 'id' is found, or if no matching entry exists in the sessions table, the script creates both. Fairly standard, I think. Now here's the weird part: in Firefox, everything works as predicted. The user gets one session, which he'll always resume upon connection, as long as 24 hours of inactivity has not elapsed. But when I visit the page in Chrome, even though it looks the same and appears to be executing queries in the same order, I see two entries in the session table. The sessions share an agent string, but the ids are different, and timestamp logs indicate that the ghost session is being created shortly (within a second) after the one created for the user. For debugging purposes, I've been printing queries to the screen as they're executed, and this is an example of what I'm seeing when Chrome should be opening one session and is somehow opening two instead: // Attempting to resume a session SELECT id FROM sessions WHERE id = '4fd24a5cd8df12.62439982' AND agent = '9bcd5c6aac911f8bcd938a9563bc4eca' // No result, so it creates a new one INSERT INTO sessions (id, agent, start, last) VALUES ('4fd24ef0347f26.72354606', '9bcd5c6aac911f8bcd938a9563bc4eca', '1339182832', '1339182832') // Clear old sessions DELETE FROM sessions WHERE last < 1339096432 And here's what I'm seeing in the database afterward: id, agent, start, last 4fd24ef0347f26.72354606, 9bcd5c6aac911f8bcd938a9563bc4eca, 1339182832, 1339182832 4fd24ef0857f94.72251285, 9bcd5c6aac911f8bcd938a9563bc4eca, 1339182833, 1339182833 Am I missing something obvious? The only thing I can think of is that Chrome might be creating a hidden session in the background, possibly to crawl the page. If that's the case though, it could become a problem later, when I begin associating active sessions with entries in the users table. I've been looking for possible bugs in my script, but I haven't found anything so far, and everything works as expected in Firefox.

• How do you traverse and store XML in Blackberry Java app?

  - by Greg

  I'm having a problem accessing the contents of an XML document. My goal is this: Take an XML source and parse it into a fair equivalent of an associative array, then store it as a persistable object. the xml is pretty simple: <root> <element> <category_id>1</category_id> <name>Cars</name> </element> <element> <category_id>2</category_id> <name>Boats</name> </element> </root> Basic java class below. I'm pretty much just calling save(xml) after http response above. Yes, the xml is properly formatted. import java.io.IOException; import java.util.Hashtable; import org.w3c.dom.Document; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import java.util.Vector; import net.rim.device.api.system.PersistentObject; import net.rim.device.api.system.PersistentStore; import net.rim.device.api.xml.parsers.DocumentBuilder; import net.rim.device.api.xml.parsers.DocumentBuilderFactory; public class database{ private static PersistentObject storeVenue; static final long key = 0x2ba5f8081f7ef332L; public Hashtable hashtable; public Vector venue_list; String _node,_element; public database() { storeVenue = PersistentStore.getPersistentObject(key); } public void save(Document xml) { venue_list = new Vector(); storeVenue.setContents(venue_list); Hashtable categories = new Hashtable(); try{ DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory. newInstance(); DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); docBuilder.isValidating(); xml.getDocumentElement ().normalize (); NodeList list=xml.getElementsByTagName("*"); _node=new String(); _element = new String(); for (int i=0;i<list.getLength();i++){ Node value=list.item(i).getChildNodes().item(0); _node=list.item(i).getNodeName(); _element=value.getNodeValue(); categories.put(_element, _node); } } catch (Exception e){ System.out.println(e.toString()); } venue_list.addElement(categories); storeVenue.commit(); } The code above is the work in progress, and is most likely heavily flawed. However, I have been at this for days now. I can never seem to get all child nodes, or the name / value pair. When I print out the vector as a string, I usually end up with results like this: [{ = root, = element}] and that's it. No "category_id", no "name" Ideally, I would end up with something like [{1 = cars, 2 = boats}] Any help is appreciated. Thanks

Currently i can`t inject my beans from web application (simple servlet) I am using glassfish v3. module limbo(ejb jar) is in dependency of module lust (war). If I use lust with compiler output of limbo everything work perfect (if ejb in web application and the are deploying together as one application). Have I messed some container configuration ? Here is my steps: I have some limbo.jar (ejb-jar) deployed to ejb container. I do not use any ejb-jar.xml, only annotations. package ua.co.inferno.limbo.persistence.beans; import javax.ejb.Remote; @Remote public interface IPersistentServiceRemote { ArrayList<String> getTerminalACPList(); ArrayList<String> getBoxACPList(); ArrayList<String> getCNPList(); ArrayList<String> getCNSList(); String getProductNamebyID(int boxid); ArrayList<String> getRegionsList(String lang); long getSequence(); void persistEntity (Object ent); } package ua.co.inferno.limbo.persistence.beans; import ua.co.inferno.limbo.persistence.entitis.EsetChSchemaEntity; import ua.co.inferno.limbo.persistence.entitis.EsetKeyActionsEntity; @Local public interface IPersistentService { ArrayList<String> getTerminalACPList(); ArrayList<String> getBoxACPList(); ArrayList<String> getCNPList(); ArrayList<String> getCNSList(); String getProductNamebyID(int boxid); ArrayList<String> getRegionsList(String lang); long getSequence(); long persistPurchaseBox(EsetRegPurchaserEntity rp); void removePurchaseTempBox(EsetRegPurchaserTempEntity rpt); EsetRegionsEntity getRegionsById(long rid); void persistEntity (Object ent); } package ua.co.inferno.limbo.persistence.beans; import ua.co.inferno.limbo.persistence.entitis.EsetChSchemaEntity; import ua.co.inferno.limbo.persistence.entitis.EsetKeyActionsEntity; import ua.co.inferno.limbo.persistence.entitis.EsetRegBoxesEntity; import javax.ejb.Stateless; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; @Stateless(name = "PersistentService") public class PersistentServiceEJB implements IPersistentService, IPersistentServiceRemote{ @PersistenceContext(unitName = "Limbo") EntityManager em; public PersistentServiceEJB() { } ......... } Than i trying to use PersistentService session bean(included in limbo.jar) from web application in lust.war (the limbo.jar & lust.war is not in ear) package ua.co.lust; import ua.co.inferno.limbo.persistence.beans.IPersistentService; import javax.ejb.EJB; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; @WebServlet(name = "ServletTest", urlPatterns = {"/"}) public class ServletTest extends HttpServlet { protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { service(request, response); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { service(request, response); } @EJB private IPersistentService pService; public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String hi = pService.getCNPList().toString(); System.out.println("testBean.hello method returned: " + hi); System.out.println("In MyServlet::init()"); System.out.println("all regions" + pService.getRegionsList("ua")); System.out.println("all regions" + pService.getBoxACPList()); } } web.xm <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <servlet> <servlet-name>ServletTest</servlet-name> <servlet-class>ua.co.lust.ServletTest</servlet-class> </servlet> </web-app> When servelt is loading i ge 404 eror (The requested resource () is not available.)

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

  - by Jialiang

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

• App Stores&ndash;In All Things, Its Quality Over Quantity

  - by D'Arcy Lussier

  Everybody has an opinion about Windows 8. People love it, people hate it, people are meh about it, people are apparently buying it from Microsoft stores in NYC as if it was water before a natural disaster…if there’s one thing that Microsoft product launches do well, its the ability to bring out strong emotional responses. Over at eweek.com, Don Reisinger wrote about 5 good and bad things about Windows 8. Yes, another opinion piece on WIndows 8. I figured since this one had good and bad it might be worthwhile to read. I then came across #10 on his list, and figured “What the hell…might as well post a bit of a rant on Windows 8 myself!” Here’s #10: 10. Bad: Too few apps Unfortunately, Microsoft wasn’t able to get too many developers to start producing applications for its Windows 8 Store. Microsoft hasn’t yet released official numbers, but some have said that the marketplace has less than 8,000 programs. Considering Apple’s App Store has 100 times that, it’s about time Microsoft starts leaning on developers to get more programs into its store. Believe me, Microsoft *has* been leaning on developers to get apps into the store. I’ve been asked at least 5 or 6 times from 5 or 6 different friends at Microsoft about whether I was going to write a Windows 8 app. I think Microsoft felt they had to try and address the number of apps available in their marketplace, since some people (like Don) would draw comparisons to the number of apps in the Apple marketplace. I feel for Microsoft in this, since the number of apps in a marketplace are an empty stat. Quality of Quantity I have an iPad that my family (wife, 10yo daughter, 3yo daughter) use. We all have our own apps installed on it. In addition, my wife has an iPhone 4S that she also installs apps on. As someone who gets asked by his kids often whether they can buy/download an app, the vast majority of the vast catalogue of iOS marketplace apps are crap! Do you realize how many “free” games are out there, only to really be not-free because you have to purchase in-game content to make the game actually playable? And how about searching – with such a vast array of apps and such high numbers of craptastic ones, trying to find something is incredibly difficult and can be frustrating. I would rather see that Microsoft has 8000 high quality apps in their store at launch, instead of 800000 that were mostly junk. Too Few Apps?! And seriously, 8000 is not a small number. How many iOS apps have I actually bought between the iPad and iPhone? I’ll be generous and say 30…heck, let’s round it up to 40. It’s not like I have 10,000 apps installed on my iPad, nor will that ever happen! So if people have, at the *launch* of a new platform ecosystem, EIGHT THOUSAND apps to choose from, I don’t see that as a fail at all! It should be noted that most of the most common apps (Netflix, Skype, etc.) are available for Windows 8 at launch – I guess I’ll have to wait a few weeks for My Pony Ranch and all its clones to start showing up; pity. Let’s Check Back in a Year So look, let’s check back in a year’s time and see what the app store looks like. My hope is that Microsoft doesn’t continue to push quantity over quality. Even knowing the optics that # of apps in the store carries and the pressure to catch Apple and Android marketplaces, I hope Microsoft avoids the scenario where there’s a good percentage of apps in the Windows Store that are utter rubbish and finding the gems will be cumbersome. But if that happens, we can thank guys like Dan who raised the false issue of app count at the launch for it.

• SQL Authority News – Presenting at SQL Bangalore on May 3, 2014 – Performing an Effective Presentation

  - by Pinal Dave

  SQL Bangalore is a wonderful community and we always have a great response when we present on technology. It is SQL User Group and we discuss everything SQL there. This month we have SQL Server 2014 theme and we are going to have a community launch on this subject. We have the best of the best speakers presenting on SQL Server 2014 technology. Looking at the whole line of celebrity speakers, I have decided not to present on SQL Server. I will be presenting on the performance tuning subject, but with the twist of soft skills. I will be presenting on “Performing an Effective Presentation“. Trust me, you do not want to miss this presentation, I will be presenting on how to present effectively when presenting SQL Server topics. What this session will NOT have I personally believe that we all are good presenters most of the time. We can all easily call out if someone is bad presenter. There is no point talking about basics like bigger bullet points, talk loudly, talk with confidence, use better analogies etc. In simple words – this is not going to some philosophy session and boring notes. What this session will have Well, this session will tell stories of my life. It will tell how we can present about technology and SQL Server with the help of stories and personal experience. I am going to tell stories about two legends  who have inspired me. Right after that we will be doing two exercises together where we will learn quickly and effectively, how to become better speaker – instantly! There is no video recording of this session. If you want to get resources from this session, please sign up my newsletter at http://bit.ly/sqllearn Here are few of the slides from this presentation: Here is the details about the event and location Venue:Microsoft Corporation, Signature Building,Embassy Golf Links Business Park, Intermediate Ring Road, Domlur, Bangalore – 560071 The agenda is amazing – we have top line SQL Speakers. Everyone is welcome and don’t forget to get your friend along for this event. Loads to learn and tons to share !!! Keynote (20 mins) by Anupam Tiwari – Business Program Manager – GTSC Backup Enhancements with SQL Server 2014 by Amit Banerjee – PFE Microsoft Performance Enhancements with SQL Server 2014 by Sourabh Agarwal - PFE Microsoft LUNCH BREAK Performing an effective Presentation by Pinal Dave – Community Member (SQLAuthority.com) InMemory Enhancements with SQL Server 2014 by Balmukund Lakhani – Support Escalation Engg.

• Call For Papers Tips and Tricks

  - by speakjava

  This year's JavaOne session review has just been completed and by now everyone who submitted papers should know whether they were successful or not.  I had the pleasure again this year of leading the review of the 'JavaFX and Rich User Experiences' track.  I thought it would be useful to write up a few comments to help people in future when submitting session proposals, not just for JavaOne, but for any of the many developer conferences that run around the world throughout the year.  This also draws on conversations I recently had with various Java User Group leaders at the Oracle User Group summit in Riga.  Many of these leaders run some of the biggest and most successful Java conferences in Europe. Try to think of a title which will sound interesting.  For example, "Experiences of performance tuning embedded Java for an ARM architecture based single board computer" probably isn't going to get as much attention as "Do you like coffee with your dessert? Java on the Raspberry Pi".  When thinking of the subject and title for your talk try to steer clear of sessions that might be too generic (and so get lost in a group of similar sessions).  Introductory talks are great when the audience is new to a subject, but beware of providing sessions that are too basic when the technology has been around for a while and there are lots of tutorials already available on the web. JavaOne, like many other conferences has a number of fields that need to be filled in when submitting a paper.  Many of these are selected from pull-down lists (like which track the session is applicable to).  Check these lists carefully.  A number of sessions we had needed to be shuffled between tracks when it was thought that the one selected was not appropriate.  We didn't count this against any sessions, but it's always a good idea to try and get the right one from the start, just in case. JavaOne, again like many other conferences, has two fields that describe the session being submitted: abstract and summary.  These are the most critical to a successful submission.  The two fields have different names and that is significant; a frequent mistake people make is to write an abstract for a session and then duplicate it for the summary.  The abstract (at least in the case of JavaOne) is what gets printed in the show guide and is typically what will be used by attendees when deciding what sessions to attend.  This is where you need to sell your session, not just to the reviewers, but also the people who you want in your audience.  Submitting a one line abstract (unless it's a really good one line) is not usually enough to decide whether this is worth investing an hour of conference time.  The abstract typically has a limit of a few hundred characters.  Try to use as many of them as possible to get as much information about your session across.  The summary should be different from the abstract (and don't leave it blank as some people do).  This field is where you can give the reviewers more detail about things like the structure of the talk, possible demonstrations and so on.  As a reviewer I look to this section to help me decide whether the hard-sell of the title and abstract will actually be reflected in the final content.  Try to make this comprehensive, but don't make it excessively long.  When you have to review possibly hundreds of sessions a certain level of conciseness can make life easier for reviewers and help the cause of your session. If you've not made many submissions for talks in the past, or if this is your first, try to give reviewers places to find background on you as a presenter.  Having an active blog and Twitter handle can also help reviewers if they're not sure what your level of expertise is.  Many call-for-papers have places for you to include this type of information.  It's always good to have new and original presenters and presentations for conferences.  Hopefully these tips will help you be successful when you answer the next call-for-papers.

• Security in OBIEE 11g, Part 2

  - by Rob Reynolds

  Continuing the series on OBIEE 11g, our guest blogger this week is Pravin Janardanam. Here is Part 2 of his overview of Security in OBIEE 11g. OBIEE 11g Security Overview, Part 2 by Pravin Janardanam In my previous blog on Security, I discussed the OBIEE 11g changes regarding Authentication mechanism, RPD protection and encryption. This blog will include a discussion about OBIEE 11g Authorization and other Security aspects. Authorization: Authorization in 10g was achieved using a combination of Users, Groups and association of privileges and object permissions to users and Groups. Two keys changes to Authorization in OBIEE 11g are: Application Roles Policies / Permission Groups Application Roles are introduced in OBIEE 11g. An application role is specific to the application. They can be mapped to other application roles defined in the same application scope and also to enterprise users or groups, and they are used in authorization decisions. Application roles in 11g take the place of Groups in 10g within OBIEE application. In OBIEE 10g, any changes to corporate LDAP groups require a corresponding change to Groups and their permission assignment. In OBIEE 11g, Application roles provide insulation between permission definitions and corporate LDAP Groups. Permissions are defined at Application Role level and changes to LDAP groups just require a reassignment of the Group to the Application Roles. Permissions and privileges are assigned to Application Roles and users in OBIEE 11g compared to Groups and Users in 10g. The diagram below shows the relationship between users, groups and application roles. Note that the Groups shown in the diagram refer to LDAP Groups (WebLogic Groups by default) and not OBIEE application Groups. The following screenshot compares the permission windows from Admin tool in 10g vs 11g. Note that the Groups in the OBIEE 10g are replaced with Application Roles in OBIEE 11g. The same is applicable to OBIEE web catalog objects.    The default Application Roles available after OBIEE 11g installation are BIAdministrator, BISystem, BIConsumer and BIAuthor. Application policies are the authorization policies that an application relies upon for controlling access to its resources. An Application Role is defined by the Application Policy. The following screenshot shows the policies defined for BIAdministrator and BISystem Roles. Note that the permission for impersonation is granted to BISystem Role. In OBIEE 10g, the permission to manage repositories and Impersonation were assigned to “Administrators” group with no control to separate these permissions in the Administrators group. Hence user “Administrator” also had the permission to impersonate. In OBI11g, BIAdministrator does not have the permission to impersonate. This gives more flexibility to have multiple users perform different administrative functions. Application Roles, Policies, association of Policies to application roles and association of users and groups to application roles are managed using Fusion Middleware Enterprise Manager (FMW EM). They reside in the policy store, identified by the system-jazn-data.xml file. The screenshots below show where they are created and managed in FMW EM. The following screenshot shows the assignment of WebLogic Groups to Application Roles. The following screenshot shows the assignment of Permissions to Application Roles (Application Policies). Note: Object level permission association to Applications Roles resides in the RPD for repository objects. Permissions and Privilege for web catalog objects resides in the OBIEE Web Catalog. Wherever Groups were used in the web catalog and RPD has been replaced with Application roles in OBIEE 11g. Following are the tools used in OBIEE 11g Security Administration: ·       Users and Groups are managed in Oracle WebLogic Administration console (by default). If WebLogic is integrated with other LDAP products, then Users and Groups needs to managed using the interface provide by the respective LDAP vendor – New in OBIEE 11g ·       Application Roles and Application Policies are managed in Oracle Enterprise Manager - Fusion Middleware Control – New in OBIEE 11g ·       Repository object permissions are managed in OBIEE Administration tool – Same as 10g but the assignment is to Application Roles instead of Groups ·       Presentation Services Catalog Permissions and Privileges are managed in OBI Application administration page - Same as 10g but the assignment is to Application Roles instead of Groups Credential Store: Credential Store is a single consolidated service provider to store and manage the application credentials securely. The credential store contains credentials that either user supplied or system generated. Credential store in OBIEE 10g is file based and is managed using cryptotools utility. In 11g, Credential store can be managed directly from the FMW Enterprise Manager and is stored in cwallet.sso file. By default, the Credential Store stores password for deployed RPDs, BI Publisher data sources and BISystem user. In addition, Credential store can be LDAP based but only Oracle Internet Directory is supported right now. As you can see OBIEE security is integrated with Oracle Fusion Middleware security architecture. This provides a common security framework for all components of Business Intelligence and Fusion Middleware applications.

• My Tech Ed North America Preview - Content Edition

  - by Chris Gardner

  As I promised in my last post, I feel the need to give you a rundown on all the technical content I am looking forward to checking out at Tech Ed this year. We shall start with the content I know I'll be able to see. This would be some demo stations in the Technical Learning Center. I will DEFINITELY be checking out the Windows Phone Device Bar. I will admit that I am a bit of a phone snob, and I just want to manhandle all that sexy, sexy tech. I am also planning on talking to the Windows Phone team and the Azure team. Year after year, I end up spending more time in either the TLC or taking certification tests than anywhere else. This leads me to the one "Exam Cram" session I hope to attend. There is a session to cram for 70-599: Designing and Developing Windows Phone Applications. I know this seems odd. I'm (sort of) an XNA guru. However, I'm not that up on my Silverlight. I know enough to add Silverlight to an XNA project. Now, let's talk breakout sessions. We always need to keep track of where we're going. I know, I talk about solving problems over forcing buzz words. However, it is important to know what those buzz words before you tell people not to use them. For this, we will look to the "What's New in Visual Studio 11" and "What's New in Microsoft .NET Framework 4.5." Of course, we do talk bad about buzz words around here. For this, I'm really looking forward to "Visual C#/Visual Basic: Becoming a Guru with Existing Features." I still have .NET 2 tricks that are crucial to my internal libraries. In depth knowledge will NEVER trump shortcut libraries. There is a session in ASP.NET for phones and tablets. For those of you that have not tried to use ASP.NET on a mobile device, there is one thing you really need to understand. Mobile devices don't use scroll bars. That's right; the thing with the least screen real estate doesn't use scroll bars. Thus, I am hoping this session will give some good advice in having an ASP.NET site target both mobile and desktop. The last "business only" session "The Accidental Team Foundation Server Admin." T & W Operations is a VERY small business. As such, I am the TFS admin because I'm the developer that is also the SQL Guru. I keep my server up, but it'd be nice to know some really cool tricks for the part time guy. This leads us the the fun sessions. Coding4Fun has a Kinect session. The Twitter followers will remember that I now have a Kinect for Windows sitting on my desk at work. I have gotten pretty handy with the device, but I KNOW I'm missing some good stuff. Finally, we come to Brian Prince's session on "Making Crazy Money with Games and the Cloud." Never mind the fact that we're using Azure at work. Never mind the fact that I'm actually using the cloud in a game. Never mind the fact that the session has the terms "Crazy Money" and "Games" in the title. If you've never seen Brian Prince speak, you're missing out. In the Hands-on-Labs, we are not allowed to make our own schedule. Instead, we're asked what sessions we can't miss, and they try to schedule around those times. This was the one session I said I couldn't miss. This should complete the technical content for the conference. Coming soon, I'll dig into the certifications I hope to attain. Then, we'll talk about the social activities for the week. Here's a preview of that. I am a member of The Krewe...

• SQL SERVER – Weekly Series – Memory Lane – #053 – Final Post in Series

  - by Pinal Dave

  It has been a fantastic journey to write memory lane series for an entire year. This series gave me the opportunity to go back and see what I have contributed to this blog throughout the last 7 years. This was indeed fantastic series as this provided me the opportunity to witness how technology has grown throughout the year and how I have progressed in my career while writing this blog post. This series was indeed fantastic experience readers as many joined during the last few years and were not sure what they have missed in recent years. Let us continue with the final episode of the Memory Lane Series. Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Get Current User – Get Logged In User Here is the straight script which list logged in SQL Server users. Disable All Triggers on a Database – Disable All Triggers on All Servers Question : How to disable all the triggers for a database? Additionally, how to disable all the triggers for all servers? For answer execute the script in the blog post. Importance of Master Database for SQL Server Startup I have received following questions many times. I will list all the questions here and answer them together. What is the purpose of Master database? Should our backup Master database? Which database is must have database for SQL Server for startup? Which are the default system database created when SQL Server 2005 is installed for the first time? What happens if Master database is corrupted? Answers to all of the questions are very much related. 2008 DECLARE Multiple Variables in One Statement SQL Server is a great product and it has many features which are very unique to SQL Server. Regarding feature of SQL Server where multiple variable can be declared in one statement, it is absolutely possible to do. 2009 How to Enable Index – How to Disable Index – Incorrect syntax near ‘ENABLE’ Many times I have seen that the index is disabled when there is a large update operation on the table. Bulk insert of very large file updates in any table using SSIS is usually preceded by disabling the index and followed by enabling the index. I have seen many developers running the following query to disable the index. 2010 List of all the Views from Database Many emails I received suggesting that they have hundreds of the view and now have no clue what is going on and how many of them have indexes and how many does not have an index. Some even asked me if there is any way they can get a list of the views with the property of Index along with it. Here is the quick script which does exactly the same. You can also include many other columns from the same view. Minimum Maximum Memory – Server Memory Options I was recently reading about SQL Server Memory Options over here. While reading this one line really caught my attention is minimum value allowed for maximum memory options. The default setting for min server memory is 0, and the default setting for max server memory is 2147483647. The minimum amount of memory you can specify for max server memory is 16 megabytes (MB). 2011 Fundamentals of Columnstore Index There are two kinds of storage in a database. Row Store and Column Store. Row store does exactly as the name suggests – stores rows of data on a page – and column store stores all the data in a column on the same page. These columns are much easier to search – instead of a query searching all the data in an entire row whether the data are relevant or not, column store queries need only to search a much lesser number of the columns. How to Ignore Columnstore Index Usage in Query In summary the question in simple words “How can we ignore using the column store index in selective queries?” Very interesting question – you can use I can understand there may be the cases when the column store index is not ideal and needs to be ignored the same. You can use the query hint IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX to ignore the column store index. The SQL Server Engine will use any other index which is best after ignoring the column store index. 2012 Storing Variable Values in Temporary Array or Temporary List SQL Server does not support arrays or a dynamic length storage mechanism like list. Absolutely there are some clever workarounds and few extra-ordinary solutions but everybody can;t come up with such solution. Additionally, sometime the requirements are very simple that doing extraordinary coding is not required. Here is the simple case. Move Database Files MDF and LDF to Another Location It is not common to keep the Database on the same location where OS is installed. Usually Database files are in SAN, Separate Disk Array or on SSDs. This is done usually for performance reason and manageability perspective. Now the challenges comes up when database which was installed at not preferred default location and needs to move to a different location. Here is the quick tutorial how you can do it. UNION ALL and ORDER BY – How to Order Table Separately While Using UNION ALL If your requirement is such that you want your top and bottom query of the UNION resultset independently sorted but in the same result set you can add an additional static column and order by that column. Let us re-create the same scenario.

• Microsoft Forcing Dev/Partners Hands on Win 8 Through Certification

  - by D'Arcy Lussier

  I remember 2.5 years ago when Microsoft dropped a bomb on the Microsoft Partner community: all Gold competencies would require .NET 4 based premiere certifications (MCPD). Problem was, this gave a window of about 6 months for partners to update their employees’ certifications. At the place I was working, I put together an aggressive plan and we were able to attain the certs needed. Microsoft is always open that the certification requirements will change as the industry changes. .NET 1.0 certifications are useless here in 2012, and rightfully so they’ve been retired for a long time now. But now we’re seeing a new tactic by Microsoft – shifting gears away from certifications that speak to what industry needs and more to the Windows 8 agenda. Consider that currently the premiere development certification is the Microsoft Certified Professional Developer, which comes in three flavours – Web, Windows, and Azure. All require WCF and Data Access exams, as well as one that deals with the associated base technologies (ASP.NET, WinForms/WPF, Azure), and one that ties all three together in a solution-based exam. For Microsoft-based organizations, these skills aren’t just valid but necessary in building Microsoft applications. But the MCPD is being replaced with our old friend Microsoft Certified Solutions Developer (MCSD). So far, Microsoft has only released two types of MCSD – Web and Windows Store Apps. Windows Store Apps?! In a push to move developers to create WinRT-based applications, desktop development is now considered a second-class citizen in the eyes of Redmond. Also interesting are the language options for the exams: HTML5 and C#. Sorry VB folks, its time to embrace curly braces whether they be JavaScript or C#. Consider too the skills being assessed for the Windows Store Apps: Get your MCSD: Windows Store Apps Using HTML5 Get your MCSD: Windows Store Apps Using C# *Image Source: http://www.microsoft.com/learning/en/us/certification/mcsd-windows-store-apps.aspx Nov 21/2012 If you look at the skills being tested in each exam, you’ll find that skills like WCF and Data Access are downplayed compared to things like integrating Charms, facilitating Search, programming for the microphone and camera – all very Windows 8 focussed items. Where this becomes maddening is that Microsoft is still pushing Windows 7 with enterprise clients. According to a ZDNet article, Microsoft wants to see Windows 7 on 70% of enterprise desktops by mid 2013. Assuming they somehow meet that (its a pretty lofty goal), there’s years of traditional desktop-based development that will still be required at some level. For those thinking they’ll just write and stick with the MCPD certification, note that most exams that go towards that certification will be retired at the end of July 2013! (Read the small print). And while details haven’t been finalized, its a safe bet that MCPD certifications eventually won’t count towards Gold-level competencies in the Microsoft Partner program. What this means for Microsoft Partners and Developers is that certification for desktop development is going to be limited to Windows Store Apps unless Microsoft re-introduces a traditional desktop (WPF) based MCSD cert. Web Application Development – It’s Not All Bad There’s big changes on the web side of certification, but I actually see these changes as being for the good! Check out the new exam requirements for MCSD – Web Applications: Get your MCSD: Web Applications certification *Image Source: http://www.microsoft.com/learning/en/us/certification/cert-mcsd-web-applications.aspx Nov 21, 2012 We now *start* with HTML5, JavaScript, and CSS3! Now I’m sure that these will be slanted towards web development in IE, and I can hear designers everywhere bemoaning the CSS/IE combination. Still, I applaud Microsoft for adopting HTML5 as the go-to web technology and requiring certified developers to prove they have skills in the basics of web dev. The fact that the second exam clearly states “MVC Web Applications” shows that Web Forms is truly legacy and deprecated. That’s not to say there aren’t those out there that are still supporting or (for whatever reason) doing new dev with Web Forms, but this move by Microsoft is telling the community they better get on the MVC bandwagon if they want to stay current. Fantastic! And of course Azure needs to be here as well, and this is where the Microsoft agenda fits in. It’s no secret that there’s been a huge push in getting developers on to Azure. I don’t see this as being a bad thing either, as cloud computing (whether Azure, private, or 3rd party) is a necessary skill for developers to have here in 2012. The cynic in me realizes that the HTML5/JavaScript/CSS push wouldn’t be as prominent though if not for the Windows 8 Store App play, where HTML5 is a first class citizen (and an available language for the MCSD Windows Store App cert). In this case, the desktop developers loss is the web developers gain. Get Ready for Changes In addition to the changes in certifications, the Microsoft Partner competencies are going through changes as well. Web and Software Development are being merged into a single competency, meaning that licenses you would have received from having both as Gold are reduced. Other competencies are either being removed or changed, as are the exam requirements. In the same way that we’re seeing faster release cycles from Microsoft, so too will we see the Microsoft Partner Program and MS Certifications evolve faster than ever before. Many of us got caught in the last wave of changes, but this time we can see the wave coming – and it looks pretty big!

• Problems using HibernateTemplate: java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;

  - by user2104160

  I am quite new in Spring world and I am going crazy trying to integrate Hibernate in Spring application using HibernateTemplate abstract support class I have the following class to persist on database table: package org.andrea.myexample.HibernateOnSpring.entity; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name="person") public class Person { @Id @GeneratedValue(strategy=GenerationType.AUTO) private int pid; private String firstname; private String lastname; public int getPid() { return pid; } public void setPid(int pid) { this.pid = pid; } public String getFirstname() { return firstname; } public void setFirstname(String firstname) { this.firstname = firstname; } public String getLastname() { return lastname; } public void setLastname(String lastname) { this.lastname = lastname; } } Next to it I have create an interface named PersonDAO in wich I only define my CRUD method. So I have implement this interface by a class named PersonDAOImpl that also extend the Spring abstract class HibernateTemplate: package org.andrea.myexample.HibernateOnSpring.dao; import java.util.List; import org.andrea.myexample.HibernateOnSpring.entity.Person; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; public class PersonDAOImpl extends HibernateDaoSupport implements PersonDAO{ public void addPerson(Person p) { getHibernateTemplate().saveOrUpdate(p); } public Person getById(int id) { // TODO Auto-generated method stub return null; } public List<Person> getPersonsList() { // TODO Auto-generated method stub return null; } public void delete(int id) { // TODO Auto-generated method stub } public void update(Person person) { // TODO Auto-generated method stub } } (at the moment I am trying to implement only the addPerson() method) Then I have create a main class to test the operation of insert a new object into the database table: package org.andrea.myexample.HibernateOnSpring; import org.andrea.myexample.HibernateOnSpring.dao.PersonDAO; import org.andrea.myexample.HibernateOnSpring.entity.Person; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class MainApp { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml"); System.out.println("Contesto recuperato: " + context); Person persona1 = new Person(); persona1.setFirstname("Pippo"); persona1.setLastname("Blabla"); System.out.println("Creato persona1: " + persona1); PersonDAO dao = (PersonDAO) context.getBean("personDAOImpl"); System.out.println("Creato dao object: " + dao); dao.addPerson(persona1); System.out.println("persona1 salvata nel database"); } } As you can see the PersonDAOImpl class extends HibernateTemplate so I think that it have to contain the operation of setting of the sessionFactory... The problem is that when I try to run this MainApp class I obtain the following exception: Exception in thread "main" java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session; at org.springframework.orm.hibernate3.SessionFactoryUtils.doGetSession(SessionFactoryUtils.java:323) at org.springframework.orm.hibernate3.SessionFactoryUtils.getSession(SessionFactoryUtils.java:235) at org.springframework.orm.hibernate3.HibernateTemplate.getSession(HibernateTemplate.java:457) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:392) at org.springframework.orm.hibernate3.HibernateTemplate.executeWithNativeSession(HibernateTemplate.java:374) at org.springframework.orm.hibernate3.HibernateTemplate.saveOrUpdate(HibernateTemplate.java:737) at org.andrea.myexample.HibernateOnSpring.dao.PersonDAOImpl.addPerson(PersonDAOImpl.java:12) at org.andrea.myexample.HibernateOnSpring.MainApp.main(MainApp.java:26) Why I have this problem? how can I solve it? To be complete I also insert my pom.xml containing my dependencies list: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.andrea.myexample</groupId> <artifactId>HibernateOnSpring</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>HibernateOnSpring</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- Dipendenze di Spring Framework --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.2.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>3.2.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.2.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>3.2.1.RELEASE</version> </dependency> <dependency> <!-- Usata da Hibernate 4 per LocalSessionFactoryBean --> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.2.0.RELEASE</version> </dependency> <!-- Dipendenze per AOP --> <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>2.2.2</version> </dependency> <!-- Dipendenze per Persistence Managment --> <dependency> <!-- Apache BasicDataSource --> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <dependency> <!-- MySQL database driver --> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.23</version> </dependency> <dependency> <!-- Hibernate --> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.1.9.Final</version> </dependency> </dependencies> </project>

• Can I disable the message line when launching ``screen -RR``

  - by Jimm Chen

  screen -RR is great. It does one of the two thing automatically: If there is any detached screen session, it picks up one can attach to it. If there is no detached screen session(no session yet, or all have been attach to other terminal), it creates a new screen session automatically. I use Windows server Remote Desktop a lot, screen -RR behaves almost the same when a client connects to a remote desktop server. It is natural and I like it. However, when screen -RR determines it should create a new session, it displays a message line at terminal bottom for 5 second. I'd like to suppress this message line because it brings us little benefit. In my opinion, a remote user can always easily distinguish whether he is connected to a resumed session(a piled-up display) or a newly created session(a clean display) from what he sees in the terminal window. So, is there a way to suppress the nag "New screen..." ? Just suppress that very one, not suppress message line globally. My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

• Sql Query - Limiting query results

  - by Gublooo

  I am quite certain we cannot use the LIMIT clause for what I want to do - so wanted to find if there are any other ways we can accomplish this. I have a table which captures which user visited which store. Every time a user visits a store, a row is inserted into this table. Some of the fields are shopping_id (primary key) store_id user_id Now what I want is - for a given set of stores, find the top 5 users who have visited the store max number of times. I can do this 1 store at a time as: select store_id,user_id,count(1) as visits from shopping where store_id = 60 group by user_id,store_id order by visits desc Limit 5 This will give me the 5 users who have visited store_id=60 the max times What I want to do is provide a list of 10 store_ids and for each store fetch the 5 users who have visited that store max times select store_id,user_id,count(1) as visits from shopping where store_id in (60,61,62,63,64,65,66) group by user_id,store_id order by visits desc Limit 5 This will not work as the Limit at the end will return only 5 rows rather than 5 rows for each store. Any ideas on how I can achieve this. I can always write a loop and pass 1 store at a time but wanted to know if there is a better way

• Auth problem on Facebook using Ruby/sinatra/frankie/facebooker

  - by user84584

  Hello guys, I'm using sinatra/frankie/facebooker to prototype something simple to test the facebook api, i'm using mmangino-facebooker the more recent version from github and I cloned the most recent version of frankie. I'm using sinatra 0.9.6. My main code is as simple as possible: before do ensure_application_is_installed_by_facebook_user @user = session[:facebook_session].user @photos = session[:facebook_session].get_photos(nil,@user.uid,nil) end get "/" do erb :index end get "/:uid/:image" do |uid,image| @photo_selected = session[:facebook_session].get_photos([image.to_i],nil,nil) erb :selected end The index page just renders a link to the other one (identified by regex "/:uid/:image") however I always get an error when it's trying to render the one identified by regex "/:uid/:image" Facebooker::Session::MissingOrInvalidParameter: Invalid parameter /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:610:in `process' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:30:in `parse' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/service.rb:67:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:600:in `post_without_logging' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:611:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/benchmark.rb:308:in `realtime' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:610:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:198:in `secure!' ./config/frankie/lib/frankie.rb:66:in `secure_with_token!' ./config/frankie/lib/frankie.rb:44:in `set_facebook_session' ./config/frankie/lib/frankie.rb:164:in `ensure_authenticated_to_facebook' ./config/frankie/lib/frankie.rb:169:in `ensure_application_is_installed_by_facebook_user' I've no idea why, it seems to be related with the auth token I guess.. I logged the request made o the fb rest server: {:sig="4f244d1f510498f4efaae3c03d036a85", :generate_session_secret="0", :method="facebook.auth.getSession", :auth_token="9dae0d02c19c680b574c78d202b0582a", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} {:call_id="1269003766.05665", :sig="194469457d1424dc8ba0678979692363", :method="facebook.photos.get", :subj_id=750401957, :session_key="2.lXL0z3s4_r573xzQwAiA9A__.3600.1269010800-750401957", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} {:sig="4f244d1f510498f4efaae3c03d036a85", :generate_session_secret="0", :method="facebook.auth.getSession", :auth_token="9dae0d02c19c680b574c78d202b0582a", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} The last one gives the error, it could be related with auth_token having the same value in the 1st and on the 3rd ? Cheers and tks, Ze Maria
