• SQL SERVER – ColumnStore Index – Batch Mode vs Row Mode

  - by pinaldave

  What do you do when you are in a hurry and hear someone say things which you do not agree or is wrong? Well, let me tell you what I do or what I recently did. I was walking by and heard someone mentioning “Columnstore Index are really great as they are using Batch Mode which makes them seriously fast.” While I was passing by and I heard this statement my first reaction was I thought Columnstore Index can use both – Batch Mode and Row Mode. I stopped by even though I was in a hurry and asked the person if he meant that Columnstore indexes are seriously fast because they use Batch Mode all the time or Batch Mode is one of the reasons for Columnstore Index to be faster. He responded that Columnstore Indexes can run only in Batch Mode. However, I do not like to confront anybody without hearing their complete story. Honestly, I like to do information sharing and avoid confronting as much as possible. There are always ways to communicate the same positively. Well, this is what I did, I quickly pull up my earlier article on Columnstore Index and copied the script to SQL Server Management Studio. I created two versions of the script. 1) Very Large Table 2) Reasonably Small Table. I a query which uses columnstore index on both of the versions. I found very interesting result of the my tests. I saved my tests and sent it to the person who mentioned about that Columnstore Indexes are using Batch Mode only. He immediately acknowledged that indeed he was incorrect in saying that Columnstore Index uses only Batch Mode. What really caught my attention is that he also thanked me for sending him detail email instead of just having argument where he and I both were standing in the corridor and neither have no way to prove any theory. Here is the screenshots of the both the scenarios. 1) Columnstore Index using Batch Mode 2) Columnstore Index using Row Mode Here is the logic behind when Columnstore Index uses Batch Mode and when it uses Row Mode. A batch typically represents about 1000 rows of data. Batch mode processing also uses algorithms that are optimized for the multicore CPUs and increased memory throughput.  Batch mode processing spreads metadata access costs and overhead over all the rows in a batch.  Batch mode processing operates on compressed data when possible leading superior performance. Here is one last point – Columnstore Index can use Batch Mode or Row Mode but Batch Mode processing is only available in Columnstore Index. I hope this statement truly sums up the whole concept.

• The Debut of Oracle Database Firewall at RSA 2011

  - by Troy Kitch

  We're very proud of the coverage and headlines Oracle Database Firewall made this past week during RSA Conference 2011 in San Francisco. In case you missed our previous post, we announced the availability of this latest addition to the Oracle Defense-in-Depth database security solutions. The announcement was picked up many publications including eWeek, CRN, InformationWeek and more. Here is just some of the press on this very important security solution: "It's rare to find a new product category these days, but I think a new product from Oracle fills the bill. In the crowded enterprise security field, that's saying something." Enterprise System Journal: A New Approach to Database Security By James E. Powell "Databases and the content they store are among the most valuable IT assets - and the most targeted by hackers. In an effort to help secure databases, Oracle today is launching the new Oracle Database Firewall as an approach to defend databases against SQL injection and other database attacks." Database Journal: Oracle Debuts Database Firewall (also appeared in InternetNews.com) By Sean Michael Kerner "Oracle Database Firewall understands SQL-statement formats, and can be configured to blacklist and whitelist traffic based on source. When it detects suspicious statements within SQL traffic -- ones that might indicate SQL injection attacks, for example -- it can replace them with neutral statements that will keep the session running without allowing potentially harmful traffic through." Network World: Oracle Database Firewall defuses SQL injection attacks By Tim Green "The firewall uses "SQL grammar analysis" to prevent SQL injection attacks and other attempts to grab information. The Oracle Database Firewall features white and black lists policies, exceptions and rules that mark the time of day, IP address, application and user." ZDNet: RSA Roundup: Oracle Database Firewall By Larry Dignan "The database giant announced Oracle Database Firewall on Feb. 14 at the RSA Conference in San Francisco. The firewall application establishes a "defensive perimeter" around databases by monitoring and enforcing normal application behavior in real-time, the company said." eWEEK: Oracle Database Firewall Delivers Vendor-Agnostic Security By Fahmida Y.

• Recover Data Like a Forensics Expert Using an Ubuntu Live CD

  - by Trevor Bekolay

  There are lots of utilities to recover deleted files, but what if you can’t boot up your computer, or the whole drive has been formatted? We’ll show you some tools that will dig deep and recover the most elusive deleted files, or even whole hard drive partitions. We’ve shown you simple ways to recover accidentally deleted files, even a simple method that can be done from an Ubuntu Live CD, but for hard disks that have been heavily corrupted, those methods aren’t going to cut it. In this article, we’ll examine four tools that can recover data from the most messed up hard drives, regardless of whether they were formatted for a Windows, Linux, or Mac computer, or even if the partition table is wiped out entirely. Note: These tools cannot recover data that has been overwritten on a hard disk. Whether a deleted file has been overwritten depends on many factors – the quicker you realize that you want to recover a file, the more likely you will be able to do so. Our setup To show these tools, we’ve set up a small 1 GB hard drive, with half of the space partitioned as ext2, a file system used in Linux, and half the space partitioned as FAT32, a file system used in older Windows systems. We stored ten random pictures on each hard drive. We then wiped the partition table from the hard drive by deleting the partitions in GParted. Is our data lost forever? Installing the tools All of the tools we’re going to use are in Ubuntu’s universe repository. To enable the repository, open Synaptic Package Manager by clicking on System in the top-left, then Administration > Synaptic Package Manager. Click on Settings > Repositories and add a check in the box labelled “Community-maintained Open Source software (universe)”. Click Close, and then in the main Synaptic Package Manager window, click the Reload button. Once the package list has reloaded, and the search index rebuilt, search for and mark for installation one or all of the following packages: testdisk, foremost, and scalpel. Testdisk includes TestDisk, which can recover lost partitions and repair boot sectors, and PhotoRec, which can recover many different types of files from tons of different file systems. Foremost, originally developed by the US Air Force Office of Special Investigations, recovers files based on their headers and other internal structures. Foremost operates on hard drives or drive image files generated by various tools. Finally, scalpel performs the same functions as foremost, but is focused on enhanced performance and lower memory usage. Scalpel may run better if you have an older machine with less RAM. Recover hard drive partitions If you can’t mount your hard drive, then its partition table might be corrupted. Before you start trying to recover your important files, it may be possible to recover one or more partitions on your drive, recovering all of your files with one step. Testdisk is the tool for the job. Start it by opening a terminal (Applications > Accessories > Terminal) and typing in: sudo testdisk If you’d like, you can create a log file, though it won’t affect how much data you recover. Once you make your choice, you’re greeted with a list of the storage media on your machine. You should be able to identify the hard drive you want to recover partitions from by its size and label. TestDisk asks you select the type of partition table to search for. In most cases (ext2/3, NTFS, FAT32, etc.) you should select Intel and press Enter. Highlight Analyse and press enter. In our case, our small hard drive has previously been formatted as NTFS. Amazingly, TestDisk finds this partition, though it is unable to recover it. It also finds the two partitions we just deleted. We are able to change their attributes, or add more partitions, but we’ll just recover them by pressing Enter. If TestDisk hasn’t found all of your partitions, you can try doing a deeper search by selecting that option with the left and right arrow keys. We only had these two partitions, so we’ll recover them by selecting Write and pressing Enter. Testdisk informs us that we will have to reboot. Note: If your Ubuntu Live CD is not persistent, then when you reboot you will have to reinstall any tools that you installed earlier. After restarting, both of our partitions are back to their original states, pictures and all. Recover files of certain types For the following examples, we deleted the 10 pictures from both partitions and then reformatted them. PhotoRec Of the three tools we’ll show, PhotoRec is the most user-friendly, despite being a console-based utility. To start recovering files, open a terminal (Applications > Accessories > Terminal) and type in: sudo photorec To begin, you are asked to select a storage device to search. You should be able to identify the right device by its size and label. Select the right device, and then hit Enter. PhotoRec asks you select the type of partition to search. In most cases (ext2/3, NTFS, FAT, etc.) you should select Intel and press Enter. You are given a list of the partitions on your selected hard drive. If you want to recover all of the files on a partition, then select Search and hit enter. However, this process can be very slow, and in our case we only want to search for pictures files, so instead we use the right arrow key to select File Opt and press Enter. PhotoRec can recover many different types of files, and deselecting each one would take a long time. Instead, we press “s” to clear all of the selections, and then find the appropriate file types – jpg, gif, and png – and select them by pressing the right arrow key. Once we’ve selected these three, we press “b” to save these selections. Press enter to return to the list of hard drive partitions. We want to search both of our partitions, so we highlight “No partition” and “Search” and then press Enter. PhotoRec prompts for a location to store the recovered files. If you have a different healthy hard drive, then we recommend storing the recovered files there. Since we’re not recovering very much, we’ll store it on the Ubuntu Live CD’s desktop. Note: Do not recover files to the hard drive you’re recovering from. PhotoRec is able to recover the 20 pictures from the partitions on our hard drive! A quick look in the recup_dir.1 directory that it creates confirms that PhotoRec has recovered all of our pictures, save for the file names. Foremost Foremost is a command-line program with no interactive interface like PhotoRec, but offers a number of command-line options to get as much data out of your had drive as possible. For a full list of options that can be tweaked via the command line, open up a terminal (Applications > Accessories > Terminal) and type in: foremost –h In our case, the command line options that we are going to use are: -t, a comma-separated list of types of files to search for. In our case, this is “jpeg,png,gif”. -v, enabling verbose-mode, giving us more information about what foremost is doing. -o, the output folder to store recovered files in. In our case, we created a directory called “foremost” on the desktop. -i, the input that will be searched for files. This can be a disk image in several different formats; however, we will use a hard disk, /dev/sda. Our foremost invocation is: sudo foremost –t jpeg,png,gif –o foremost –v –i /dev/sda Your invocation will differ depending on what you’re searching for and where you’re searching for it. Foremost is able to recover 17 of the 20 files stored on the hard drive. Looking at the files, we can confirm that these files were recovered relatively well, though we can see some errors in the thumbnail for 00622449.jpg. Part of this may be due to the ext2 filesystem. Foremost recommends using the –d command-line option for Linux file systems like ext2. We’ll run foremost again, adding the –d command-line option to our foremost invocation: sudo foremost –t jpeg,png,gif –d –o foremost –v –i /dev/sda This time, foremost is able to recover all 20 images! A final look at the pictures reveals that the pictures were recovered with no problems. Scalpel Scalpel is another powerful program that, like Foremost, is heavily configurable. Unlike Foremost, Scalpel requires you to edit a configuration file before attempting any data recovery. Any text editor will do, but we’ll use gedit to change the configuration file. In a terminal window (Applications > Accessories > Terminal), type in: sudo gedit /etc/scalpel/scalpel.conf scalpel.conf contains information about a number of different file types. Scroll through this file and uncomment lines that start with a file type that you want to recover (i.e. remove the “#” character at the start of those lines). Save the file and close it. Return to the terminal window. Scalpel also has a ton of command-line options that can help you search quickly and effectively; however, we’ll just define the input device (/dev/sda) and the output folder (a folder called “scalpel” that we created on the desktop). Our invocation is: sudo scalpel /dev/sda –o scalpel Scalpel is able to recover 18 of our 20 files. A quick look at the files scalpel recovered reveals that most of our files were recovered successfully, though there were some problems (e.g. 00000012.jpg). Conclusion In our quick toy example, TestDisk was able to recover two deleted partitions, and PhotoRec and Foremost were able to recover all 20 deleted images. Scalpel recovered most of the files, but it’s very likely that playing with the command-line options for scalpel would have enabled us to recover all 20 images. These tools are lifesavers when something goes wrong with your hard drive. If your data is on the hard drive somewhere, then one of these tools will track it down!

• Why don't I have write permission to my vmware virtual network device?

  - by Robert Martin

  I want to allow my VMWare machine to force the virtual network it's on into promiscuous mode so I can play around with honeyd. I received an error message that told me to go to http://vmware.com/info?id=161 to allow this behavior. Based on their advice, I did: $ groupadd promiscuous $ cat /etc/group | grep promiscuous promiscuous:x:1002:robert $ usermod -a -G promiscuous robert $ id robert uid=1000(robert) gid=1000(robert) groups=1000(robert),....,1002(promiscuous) $ chgrp newgroup /dev/vmnet8 $ chmod g+rw /dev/vmnet8 $ ls -l /dev/vmnet8 crw-rw---- 1 root promiscuous 119, 8 2012-03-29 10:29 /dev/vmnet8 Looks like I gave RW permission to the promiscuous group, and added myself. Except that VMWare still gives me an error message that says I cannot enter promiscuous mode. To try out the group thing, I tried: $ echo "1" >/dev/vmnet8 bash: /dev/vmnet8: Permission denied That really surprised me: It makes me think that I still haven't properly given myself the correct permissions... What am I missing?

• Mac OS X: How do I disable SSID Broadcasting with Internet Sharing over Airport?

  - by Jack Chu

  I'm currently using Internet Sharing from my Ethernet over Airport on my Macbook Pro, however I don't want my SSID broadcasted†. There doesn't seem to be an option in Sharing/System Preferences to hide my ssid or prevent broadcasting. Any ideas? † My parent's restaurant has a wifi router, but it's on the roof level where the cable was installed. The signal it gets is weak, but works for the macbook. Their iPhones and 802.11G based computers can't get the wifi connection, maybe 802.11N on the macbook gets better penetration. I figure they could use the airport sharing from the laptop. For a restaurant type setting I don't think having WPA or WPA2 is super important. There's nothing sensitive or insecure on the network, so I figure hiding the SSID would be good enough for their purposes. It's not even active 100% of the time.

• Uploading and Importing CSV file to SQL Server in ASP.NET WebForms

  - by Vincent Maverick Durano

  Few weeks ago I was working with a small internal project  that involves importing CSV file to Sql Server database and thought I'd share the simple implementation that I did on the project. In this post I will demonstrate how to upload and import CSV file to SQL Server database. As some may have already know, importing CSV file to SQL Server is easy and simple but difficulties arise when the CSV file contains, many columns with different data types. Basically, the provider cannot differentiate data types between the columns or the rows, blindly it will consider them as a data type based on first few rows and leave all the data which does not match the data type. To overcome this problem, I used schema.ini file to define the data type of the CSV file and allow the provider to read that and recognize the exact data types of each column. Now what is schema.ini? Taken from the documentation: The Schema.ini is a information file, used to define the data structure and format of each column that contains data in the CSV file. If schema.ini file exists in the directory, Microsoft.Jet.OLEDB provider automatically reads it and recognizes the data type information of each column in the CSV file. Thus, the provider intelligently avoids the misinterpretation of data types before inserting the data into the database. For more information see: http://msdn.microsoft.com/en-us/library/ms709353%28VS.85%29.aspx Points to remember before creating schema.ini:   1. The schema information file, must always named as 'schema.ini'.   2. The schema.ini file must be kept in the same directory where the CSV file exists.   3. The schema.ini file must be created before reading the CSV file.   4. The first line of the schema.ini, must the name of the CSV file, followed by the properties of the CSV file, and then the properties of the each column in the CSV file. Here's an example of how the schema looked like: [Employee.csv] ColNameHeader=False Format=CSVDelimited DateTimeFormat=dd-MMM-yyyy Col1=EmployeeID Long Col2=EmployeeFirstName Text Width 100 Col3=EmployeeLastName Text Width 50 Col4=EmployeeEmailAddress Text Width 50 To get started lets's go a head and create a simple blank database. Just for the purpose of this demo I created a database called TestDB. After creating the database then lets go a head and fire up Visual Studio and then create a new WebApplication project. Under the root application create a folder called UploadedCSVFiles and then place the schema.ini on that folder. The uploaded CSV files will be stored in this folder after the user imports the file. Now add a WebForm in the project and set up the HTML mark up and add one (1) FileUpload control one(1)Button and three (3) Label controls. After that we can now proceed with the codes for uploading and importing the CSV file to SQL Server database. Here are the full code blocks below: 1: using System; 2: using System.Data; 3: using System.Data.SqlClient; 4: using System.Data.OleDb; 5: using System.IO; 6: using System.Text; 7:   8: namespace WebApplication1 9: { 10: public partial class CSVToSQLImporting : System.Web.UI.Page 11: { 12: private string GetConnectionString() 13: { 14: return System.Configuration.ConfigurationManager.ConnectionStrings["DBConnectionString"].ConnectionString; 15: } 16: private void CreateDatabaseTable(DataTable dt, string tableName) 17: { 18:   19: string sqlQuery = string.Empty; 20: string sqlDBType = string.Empty; 21: string dataType = string.Empty; 22: int maxLength = 0; 23: StringBuilder sb = new StringBuilder(); 24:   25: sb.AppendFormat(string.Format("CREATE TABLE {0} (", tableName)); 26:   27: for (int i = 0; i < dt.Columns.Count; i++) 28: { 29: dataType = dt.Columns[i].DataType.ToString(); 30: if (dataType == "System.Int32") 31: { 32: sqlDBType = "INT"; 33: } 34: else if (dataType == "System.String") 35: { 36: sqlDBType = "NVARCHAR"; 37: maxLength = dt.Columns[i].MaxLength; 38: } 39:   40: if (maxLength > 0) 41: { 42: sb.AppendFormat(string.Format(" {0} {1} ({2}), ", dt.Columns[i].ColumnName, sqlDBType, maxLength)); 43: } 44: else 45: { 46: sb.AppendFormat(string.Format(" {0} {1}, ", dt.Columns[i].ColumnName, sqlDBType)); 47: } 48: } 49:   50: sqlQuery = sb.ToString(); 51: sqlQuery = sqlQuery.Trim().TrimEnd(','); 52: sqlQuery = sqlQuery + " )"; 53:   54: using (SqlConnection sqlConn = new SqlConnection(GetConnectionString())) 55: { 56: sqlConn.Open(); 57: SqlCommand sqlCmd = new SqlCommand(sqlQuery, sqlConn); 58: sqlCmd.ExecuteNonQuery(); 59: sqlConn.Close(); 60: } 61:   62: } 63: private void LoadDataToDatabase(string tableName, string fileFullPath, string delimeter) 64: { 65: string sqlQuery = string.Empty; 66: StringBuilder sb = new StringBuilder(); 67:   68: sb.AppendFormat(string.Format("BULK INSERT {0} ", tableName)); 69: sb.AppendFormat(string.Format(" FROM '{0}'", fileFullPath)); 70: sb.AppendFormat(string.Format(" WITH ( FIELDTERMINATOR = '{0}' , ROWTERMINATOR = '\n' )", delimeter)); 71:   72: sqlQuery = sb.ToString(); 73:   74: using (SqlConnection sqlConn = new SqlConnection(GetConnectionString())) 75: { 76: sqlConn.Open(); 77: SqlCommand sqlCmd = new SqlCommand(sqlQuery, sqlConn); 78: sqlCmd.ExecuteNonQuery(); 79: sqlConn.Close(); 80: } 81: } 82: protected void Page_Load(object sender, EventArgs e) 83: { 84:   85: } 86: protected void BTNImport_Click(object sender, EventArgs e) 87: { 88: if (FileUpload1.HasFile) 89: { 90: FileInfo fileInfo = new FileInfo(FileUpload1.PostedFile.FileName); 91: if (fileInfo.Name.Contains(".csv")) 92: { 93:   94: string fileName = fileInfo.Name.Replace(".csv", "").ToString(); 95: string csvFilePath = Server.MapPath("UploadedCSVFiles") + "\\" + fileInfo.Name; 96:   97: //Save the CSV file in the Server inside 'MyCSVFolder' 98: FileUpload1.SaveAs(csvFilePath); 99:   100: //Fetch the location of CSV file 101: string filePath = Server.MapPath("UploadedCSVFiles") + "\\"; 102: string strSql = "SELECT * FROM [" + fileInfo.Name + "]"; 103: string strCSVConnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";" + "Extended Properties='text;HDR=YES;'"; 104:   105: // load the data from CSV to DataTable 106:   107: OleDbDataAdapter adapter = new OleDbDataAdapter(strSql, strCSVConnString); 108: DataTable dtCSV = new DataTable(); 109: DataTable dtSchema = new DataTable(); 110:   111: adapter.FillSchema(dtCSV, SchemaType.Mapped); 112: adapter.Fill(dtCSV); 113:   114: if (dtCSV.Rows.Count > 0) 115: { 116: CreateDatabaseTable(dtCSV, fileName); 117: Label2.Text = string.Format("The table ({0}) has been successfully created to the database.", fileName); 118:   119: string fileFullPath = filePath + fileInfo.Name; 120: LoadDataToDatabase(fileName, fileFullPath, ","); 121:   122: Label1.Text = string.Format("({0}) records has been loaded to the table {1}.", dtCSV.Rows.Count, fileName); 123: } 124: else 125: { 126: LBLError.Text = "File is empty."; 127: } 128: } 129: else 130: { 131: LBLError.Text = "Unable to recognize file."; 132: } 133:   134: } 135: } 136: } 137: } The code above consists of three (3) private methods which are the GetConnectionString(), CreateDatabaseTable() and LoadDataToDatabase(). The GetConnectionString() is a method that returns a string. This method basically gets the connection string that is configured in the web.config file. The CreateDatabaseTable() is method that accepts two (2) parameters which are the DataTable and the filename. As the method name already suggested, this method automatically create a Table to the database based on the source DataTable and the filename of the CSV file. The LoadDataToDatabase() is a method that accepts three (3) parameters which are the tableName, fileFullPath and delimeter value. This method is where the actual saving or importing of data from CSV to SQL server happend. The codes at BTNImport_Click event handles the uploading of CSV file to the specified location and at the same time this is where the CreateDatabaseTable() and LoadDataToDatabase() are being called. If you notice I also added some basic trappings and validations within that event. Now to test the importing utility then let's create a simple data in a CSV format. Just for the simplicity of this demo let's create a CSV file and name it as "Employee" and add some data on it. Here's an example below: 1,VMS,Durano,[email protected] 2,Jennifer,Cortes,[email protected] 3,Xhaiden,Durano,[email protected] 4,Angel,Santos,[email protected] 5,Kier,Binks,[email protected] 6,Erika,Bird,[email protected] 7,Vianne,Durano,[email protected] 8,Lilibeth,Tree,[email protected] 9,Bon,Bolger,[email protected] 10,Brian,Jones,[email protected] Now save the newly created CSV file in some location in your hard drive. Okay let's run the application and browse the CSV file that we have just created. Take a look at the sample screen shots below: After browsing the CSV file. After clicking the Import Button Now if we look at the database that we have created earlier you'll notice that the Employee table is created with the imported data on it. See below screen shot.   That's it! I hope someone find this post useful! Technorati Tags: ASP.NET,CSV,SQL,C#,ADO.NET

• Information regarding Collection 6233 - Implementing and Maintaining Business Intelligence in Micros

  - by Testas

  At the London SQL Server User Group I was asked a number of questions regarding the release of Collection 6233 - Implementing and Maintaining Business Intelligence in Microsoft® SQL Server® 2008: Integration Services, Reporting Services and Analysis Services, which has been authored by myself. Particularly regarding the SSIS component of the collection. Elearning is an interactive training experience that enables you to learn at your own pace. With a variety of learning tools including demonstrations, animations as well as written materials and the addition of labs that enables you to reinforce your learning. Microsoft Elearning can provide a valuable learning tool when you may not have the time to take out of the office to attend a courseThis 24-hour collection provides you with the skills and knowledge required to implement and maintain business intelligence solutions on SQL Server 2008 and also helps students to prepare for Exam 70-448 and you can buy each part individually see: http://www.microsoft.com/learning/elearning/course/6233.mspx   However, you will create a simple data warehouse in this collection and use SSIS to create packages to populate the data warehouse with data, exploring key concepts and tools to faciliatate this. This was a decision thart I took when writing this course based on feedback from hundreds of students who attended Microsoft Official Courses on SSIS. They wanted a course that allowed them to use SSIS to work with a data warehouse. This collection will certainly enable you to explore the options available in SSIS to meet this requirement while at the same time meeting the certification requirements I hope this answers the questions regarding this collection and hope you enjoy this collection   Chris

• SQL SERVER – What is Fill Factor and What is the Best Value for Fill Factor

  - by pinaldave

  Working in performance tuning area, one has to know about Index and Index Maintenance. For any Index the most important property is Fill Factor. Fill factor is the value that determines the percentage of space on each leaf-level page to be filled with data. In an SQL Server, the smallest unit is a page, which is made of  Page with size 8K. Every page can store one or more rows based on the size of the row. The default value of the Fill Factor is 100, which is same as value 0. The default Fill Factor (100 or 0) will allow the SQL Server to fill the leaf-level pages of an index with the maximum numbers of the rows it can fit. There will be no or very little empty space left in the page, when the fill factor is 100. I have written following two article about Fill Factor. What is Fill factor? – Index, Fill Factor and Performance – Part 1 What is the best value for the Fill Factor? – Index, Fill Factor and Performance – Part 2 I strongly encourage read them and provide your feedback.

• The importance of Unit Testing in BI

  - by Davide Mauri

  One of the main steps in the process we internally use to develop a BI solution is the implementation of Unit Test of you BI Data. As you may already know, I’ve create a simple (for now) tool that leverages NUnit to allow us to quickly create Unit Testing without having to resort to use Visual Studio Database Professional: http://queryunit.codeplex.com/ Once you have a tool like this one, you can start also to make sure that your BI solution (DWH and CUBE) is not only structurally sound (I mean, the cube or the report gets processed correctly), but you can also check that the logical integrity of your business rules is enforced. For example let’s say that the customer tell you that they will never create an invoice for a specific product-line in 2010 since that product-line is dismissed and will never be sold again. Ok we know that this in theory is true, but a lot of this business rule effectiveness depends on the fact the people does not do a mistake while inserting new orders/invoices and the ERP used implements a check for this business logic. Unfortunately these last two hypotesis are not always true, so you may find yourself really having some invoices for a product line that doesn’t exists anymore. Maybe this kind of situation in future will be solved using Master Data Management but, meanwhile, how you can give and idea of the data quality to your customers? How can you check that logical integrity of the analytical data you produce is exactly what you expect? Well, Unit Testing of a DWH or a CUBE can be a solution. Once you have defined your test suite, by writing SQL and MDX queries that checks that your data is what you expect to be, if you use NUnit (and QueryUnit does), you can then use a tool like NUnit2Report to create a nice HTML report that can be shipped via email to give information of data quality: In addition to that, since NUnit produces an XML file as a result, you can also import it into a SQL Server Database and then monitor the quality of data over time. I’ll be speaking about this approach (and more in general about how to “engineer” a BI solution) at the next European SQL PASS Adaptive BI Best Practices http://www.sqlpass.org/summit/eu2010/Agenda/ProgramSessions/AdaptiveBIBestPratices.aspx I’ll enjoy discussing with you all about this, so see you there!

• Configure Oracle SOA JMSAdatper to Work with WLS JMS Topics

  - by fip

  The WebLogic JMS Topic are typically running in a WLS cluster. So as your SOA composites that receive these Topic messages. In some situation, the two clusters are the same while in others they are sepearate. The composites in SOA cluster are subscribers to the JMS Topic in WebLogic cluster. As nature of JMS Topic is meant to distribute the same copy of messages to all its subscribers, two questions arise immediately when it comes to load balancing the JMS Topic messages against the SOA composites: How to assure all of the SOA cluster members receive different messages instead of the same (duplicate) messages, even though the SOA cluster members are all subscribers to the Topic? How to make sure the messages are evenly distributed (load balanced) to SOA cluster members? Here we will walk through how to configure the JMS Topic, the JmsAdapter connection factory, as well as the composite so that the JMS Topic messages will be evenly distributed to same composite running off different SOA cluster nodes without causing duplication. 2. The typical configuration In this typical configuration, we achieve the load balancing of JMS Topic messages to JmsAdapters by configuring a partitioned distributed topic along with sharable subscriptions. You can reference the documentation for explanation of PDT. And this blog posting does a very good job to visually explain how this combination of configurations would message load balancing among clients of JMS Topics. Our job is to apply this configuration in the context of SOA JMS Adapters. To do so would involve the following steps: Step A. Configure JMS Topic to be UDD and PDT, at the WebLogic cluster that house the JMS Topic Step B. Configure JCA Connection Factory with proper ServerProperties at the SOA cluster Step C. Reference the JCA Connection Factory and define a durable subscriber name, at composite's JmsAdapter (or the *.jca file) Here are more details of each step: Step A. Configure JMS Topic to be UDD and PDT, You do this at the WebLogic cluster that house the JMS Topic. You can follow the instructions at Administration Console Online Help to create a Uniform Distributed Topic. If you use WebLogic Console, then at the same administration screen you can specify "Distribution Type" to be "Uniform", and the Forwarding policy to "Partitioned", which would make the JMS Topic Uniform Distributed Destination and a Partitioned Distributed Topic, respectively Step B: Configure ServerProperties of JCA Connection Factory You do this step at the SOA cluster. This step is to make the JmsAdapter that connect to the JMS Topic through this JCA Connection Factory as a certain type of "client". When you configure the JCA Connection Factory for the JmsAdapter, you define the list of properties in FactoryProperties field, in a semi colon separated list: ClientID=myClient;ClientIDPolicy=UNRESTRICTED;SubscriptionSharingPolicy=SHARABLE;TopicMessageDistributionAll=false You can refer to Chapter 8.4.10 Accessing Distributed Destinations (Queues and Topics) on the WebLogic Server JMS of the Adapter User Guide for the meaning of these properties. Please note: Except for ClientID, other properties such as the ClientIDPolicy=UNRESTRICTED, SubscriptionSharingPolicy=SHARABLE and TopicMessageDistributionAll=false are all default settings for the JmsAdapter's connection factory. Therefore you do NOT have to explicitly specify them explicitly. All you need to do is the specify the ClientID. The ClientID is different from the subscriber ID that we are to discuss in the later steps. To make it simple, you just need to remember you need to specify the client ID and make it unique per connection factory. Here is the example setting: Step C. Reference the JCA Connection Factory and define a durable subscriber name, at composite's JmsAdapter (or the *.jca file) In the following example, the value 'MySubscriberID-1' was given as the value of property 'DurableSubscriber': <adapter-config name="subscribe" adapter="JMS Adapter" wsdlLocation="subscribe.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata"> <connection-factory location="eis/wls/MyTestUDDTopic" UIJmsProvider="WLSJMS" UIConnectionName="ateam-hq24b"/> <endpoint-activation portType="Consume_Message_ptt" operation="Consume_Message"> <activation-spec className="oracle.tip.adapter.jms.inbound.JmsConsumeActivationSpec"> <property name="DurableSubscriber" value="MySubscriberID-1"/> <property name="PayloadType" value="TextMessage"/> <property name="UseMessageListener" value="false"/> <property name="DestinationName" value="jms/MyTestUDDTopic"/> </activation-spec> </endpoint-activation> </adapter-config> You can set the durable subscriber name either at composite's JmsAdapter wizard,or by directly editing the JmsAdapter's *.jca file within the Composite project. 2.The "atypical" configurations: For some systems, there may be restrictions that do not allow the afore mentioned "typical" configurations be applied. For examples, some deployments may be required to configure the JMS Topic to be Replicated Distributed Topic rather than Partition Distributed Topic. We would like to discuss those scenarios here: Configuration A: The JMS Topic is NOT PDT In this case, you need to define the message selector 'NOT JMS_WL_DDForwarded' in the adapter's *.jca file, to filter out those "replicated" messages. Configuration B. The ClientIDPolicy=RESTRICTED In this case, you need separate factories for different composites. More accurately, you need separate factories for different *.jca file of JmsAdapter.

• Option Trading: Getting the most out of the event session options

  - by extended_events

  You can control different aspects of how an event session behaves by setting the event session options as part of the CREATE EVENT SESSION DDL. The default settings for the event session options are designed to handle most of the common event collection situations so I generally recommend that you just use the defaults. Like everything in the real world though, there are going to be a handful of “special cases” that require something different. This post focuses on identifying the special cases and the correct use of the options to accommodate those cases. There is a reason it’s called Default The default session options specify a total event buffer size of 4 MB with a 30 second latency. Translating this into human terms; this means that our default behavior is that the system will start processing events from the event buffer when we reach about 1.3 MB of events or after 30 seconds, which ever comes first. Aside: What’s up with the 1.3 MB, I thought you said the buffer was 4 MB?The Extended Events engine takes the total buffer size specified by MAX_MEMORY (4MB by default) and divides it into 3 equally sized buffers. This is done so that a session can be publishing events to one buffer while other buffers are being processed. There are always at least three buffers; how to get more than three is covered later. Using this configuration, the Extended Events engine can “keep up” with most event sessions on standard workloads. Why is this? The fact is that most events are small, really small; on the order of a couple hundred bytes. Even when you start considering events that carry dynamically sized data (eg. binary, text, etc.) or adding actions that collect additional data, the total size of the event is still likely to be pretty small. This means that each buffer can likely hold thousands of events before it has to be processed. When the event buffers are finally processed there is an economy of scale achieved since most targets support bulk processing of the events so they are processed at the buffer level rather than the individual event level. When all this is working together it’s more likely that a full buffer will be processed and put back into the ready queue before the remaining buffers (remember, there are at least three) are full. I know what you’re going to say: “My server is exceptional! My workload is so massive it defies categorization!” OK, maybe you weren’t going to say that exactly, but you were probably thinking it. The point is that there are situations that won’t be covered by the Default, but that’s a good place to start and this post assumes you’ve started there so that you have something to look at in order to determine if you do have a special case that needs different settings. So let’s get to the special cases… What event just fired?! How about now?! Now?! If you believe the commercial adage from Heinz Ketchup (Heinz Slow Good Ketchup ad on You Tube), some things are worth the wait. This is not a belief held by most DBAs, particularly DBAs who are looking for an answer to a troubleshooting question fast. If you’re one of these anxious DBAs, or maybe just a Program Manager doing a demo, then 30 seconds might be longer than you’re comfortable waiting. If you find yourself in this situation then consider changing the MAX_DISPATCH_LATENCY option for your event session. This option will force the event buffers to be processed based on your time schedule. This option only makes sense for the asynchronous targets since those are the ones where we allow events to build up in the event buffer – if you’re using one of the synchronous targets this option isn’t relevant. Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers   Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is  largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• CentOS 5.5 APIC issue on ESX 4.1 & ML115

  - by Adnan

  Hi, I've just installed vSphere 4.1 on an HP ProLiant ML115 G5 Quad-core and am trying to install CentOS 5.5 as a guest system. However, when the guest boots up I get a calibrate_APIC_clock warning and a kernel panic message. I've come across this knowledge base article on the vmware website which suggests moving the guest onto another Intel based host (!). Funnily enough I don't have a collection of spare host servers sitting around, so can anyone suggest another solution? Alternatively, would installing an earlier version of CentOS get around this issue, or would a yum update put me back to square one? How about BIOS settings, could anything be tweaked there? Thanks.

• Good book for a software developer doing part-time (Linux) system administration work

  - by Tony Meyer

  In many smaller organisations, developers often end up doing some system administration work (for obvious reasons). A lot of the time, they have great developer skills, but few system administration skills (perhaps all self-taught), and so have to learn as they go, which is fairly inefficient. Are there canonical (or simply great) books that would help in this situation? More advanced than just using a shell (presumably a developer can do that), but not aimed at someone that hopes to spend many years doing this work. Ideally, something fairly generic (although specific to a distribution would be OK), covering databases, networking, general maintenance, etc, not just one specific task. For the most part, I'm interested in shell-based work (i.e. no GUI installed), although if there's something outstanding I'm missing, please point it out. (As an analogy, replace "system administration" with C, and I'd want K&R, with C++ and I'd want Meyers' "Effective C++").

• Exchange not preserving the "To:" field

  - by Matt Simmons

  I've got a hosted exchange solution through Apptix, which isn't the problem, I think, but it may be relevant. I have my main account, [email protected], and to that, I have an alias, [email protected]. Whenever I send an email to [email protected], I examine the headers, and I see the "To:" field being correct, "To: [email protected]". All is well. I recently set up another user, [email protected] to function as a multipurpose mailbox. I aliased "[email protected]" to the services account in the same method that I did "[email protected]", however nothing I have sent to "[email protected]" actually goes TO "[email protected]". All of the headers say "To: [email protected]". This makes it extremely difficult to filter based on headers alone. Does anyone have any feedback on what settings I would need to look at in order to fix that?

• NFS caching on Ubuntu

  - by stream

  We run a bunch of ubuntu servers (mostly 8.04 LTS) which all mount an nfs share at /nfs. We use the nfs primarily for two purposes: symlinking config files (such as apache vhosts) reading & writing uploaded files This all works great except it makes us fully dependent on the central NFS server (which is a DRBD cluster with heartbeat failover from primary to secondary, but we've still seen issues). What we'd like is if we could mount the NFS through some local caching layer which would make any file which had previously been read remain available even if /nfs isn't. Writes could be disabled for this period. Searching around it looks like cachefilesd may be an option. Unfortunately, it's only packaged for ubuntu 9.10 & 10.04 it looks like. I was also looking for a FUSE-based solution which might fit the bill, but hadn't found anything yet. Any suggestions would be greatly appreciated!

• Ground Control by David Baum

  - by JuergenKress

  As cloud computing moves out of the early-adopter phase, organizations are carefully evaluating how to get to the cloud. They are examining standard methods for developing, integrating, deploying, and scaling their cloud applications, and after weighing their choices, they are choosing to develop and deploy cloud applications based on Oracle Cloud Application Foundation, part of Oracle Fusion Middleware. Oracle WebLogic Server is the flagship software product of Oracle Cloud Application Foundation. Oracle WebLogic Server is optimized to run on Oracle Exalogic Elastic Cloud, the integrated hardware and software platform for the Oracle Cloud Application Foundation family. Many companies, including Reliance Commercial Finance, are adopting this middleware infrastructure to enable private cloud computing and its convenient, on-demand access to a shared pool of configurable computing resources. “Cloud computing has become an extremely critical design factor for us,” says Shashi Kumar Ravulapaty, senior vice president and chief technology officer at Reliance Commercial Finance. “It’s one of our main focus areas. Oracle Exalogic, especially in combination with Oracle WebLogic, is a perfect fit for rapidly provisioning capacity in a private cloud infrastructure.” Reliance Commercial Finance provides loans to tens of thousands of customers throughout India. With more than 1,500 employees accessing the company’s core business applications every day, the company was having trouble processing more than 6,000 daily transactions with its legacy infrastructure, especially at the end of each month when hundreds of concurrent users need to access the company’s loan processing and approval applications.

• Oracle B2B 11g - Transport Layer Acknowledgement

  - by Nitesh Jain Oracle

  In Health Care Industry,Acknowledgement or Response should be sent back very fast. Once any message received, Acknowledgement should be sent back to TP. Oracle B2B provides a solution to send acknowledgement or Response from transport layer of mllp that is called as immediate acknowledgment. Immediate acknowledgment is generated and transmitted in the transport layer. It is an alternative to the functional acknowledgment, which generates after processing/validating the data in document layer. Oracle B2B provides four types of immediate acknowledgment: Default: Oracle B2B parses the incoming HL7 message and generates an acknowledgment from it. This mode uses the details from incoming payload and generate the acknowledgement based on incoming HL7 message control number, sender and application identification. By default, an Immediate ACK is a generic ACK. Trigger event can also sent back by using Map Trigger Event property. If mapping the MSH.10 of the ACK with the MSH.10 of the incoming business message is required, then enable the Map ACK Control ID property. Simple: B2B sends the predefined acknowledgment message to the sender without parsing the incoming message. Custom: Custom immediate Ack/Response mode gives a user to define their own response/acknowledgement. This is configurable using file in the Custom Immediate ACK File property. Negative: In this case, immediate ACK will be returned only in the case of exceptions.

• eLearning event on HTML5 for Mobile with jQuery Mobile

  - by Wallym

  I'll be doing an eLearning event on HTML5 for Mobile with jQuery Mobile. There will also be a few items sprinkled in on ASP.NET Razor. Mobile development is a hot item. Customers are buying iPhones, iPads, Android devices, and many other mobile computing devices at an ever increasing record pace. Devices based on iOS and Android are nearly 80 percent of the marketplace. RIM continues to be dominant in the business area across the world. Nokia's growth with Windows Phone will grow on a worldwide basis. At the same time, clearly web development is a tremendous driver of applications, both on the public Internet and on private networks. How can developers target these various mobile platforms with web technologies? Developers can write web applications that take advantage of each mobile platform, but that is a lot of work. Into this space, the jQuery Mobile framework was developed. This eLearning series will provide an overview of mobile web development with jQuery Mobile, a detailed look at what the jQuery Mobile framework provides for us, how we can customize jQuery Mobile, and how we can use jQuery Mobile inside of ASP.NET.Link: http://elearning.left-brain.com/event/mobile-web-development

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

  - by Jim Duffy

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

• IASA South East Florida Chapter Meeting Recap - June 2011

  - by Sam Abraham

  Erik Russell and Giles Marino were our speakers for the June 2011 IASA South East Florida Chapter meeting.    Attendees filled all available seats at the Microsoft office conference room where the event was held. This highlights the high interest in Enterprise Architecture as a career track and chartered project role. Also in attendance were our Board of Directors and Alex Funkhouser, President, Sherlock Technology.   Rainer Habermann, Chapter President, kicked off the meeting by introducing our speakers and Board of Directors.   Alex Funkhouser, President of South Florida’s staffing firm Sherlock Technology spoke briefly about available Software Architect positions in the area. Alex also congratulated and presented this week’s Sherlock Raffle winner with $500 in cash.   Our speakers Giles and Erik then proceeded with their talk. Erik presented a business case in the government sector where Enterprise Architecture helped a government entity cut costs and streamline its various business operations. Technologies leveraged in Erik’s demonstrated project were Java-based.   Giles then followed with a thorough demonstration of the Architecture patterns he used to migrate a complete backend system for an insurance company to the .Net Platform.   Audience was very engaged with our speakers as evidenced by the large number of follow-up questions asked at the end of the talk.   We greatly enjoyed Giles and Erik’s talk and look forward to having them share with us more of their adventures as Enterprise Architects in the near future.   Below are some photos of the event.   Sam Abraham Secretary- IASA South East Florida Chapter. http://www.iasaglobal.org/iasa/South_East_Florida.asp Chapter President - Rainer Habermann kicks off our meeting.   Sherlock Technology President Alex Funkhouser holding Sherlock's weekly cash prize.

• SBS2003 OWA not displaying images on external side

  - by JasonC

  I've got an SBS 2003 server with companyweb/remote owa site. After authenticating remotely to the https:/servername/remote site, and then clicking on Use Outlook Web Access, the mail/owa site displays only limited amounts of data with Loading... displayed (see first image). This is different when viewing the site on the server itself (see second image). Different browsers will display different types of data (last screenshot is Chrome - first two are IE). I feel IIS permissions on the virtual directories is the cause, but not certain. Forms-based authentication etc is working ok etc. Any suggestions? Authentication and getting email via ActiveSync is not a problem. I don't want to break anything, and it's not a major problem because the users only get their email via outlook and iphones anyway without problems. I'm more interested in finding out for my own info so please give me some suggestions to try. Thanks for looking!

• General Overview of Design Pattern Types

  Typically most software engineering design patterns fall into one of three categories in regards to types. Three types of software design patterns include: Creational Type Patterns Structural Type Patterns Behavioral Type Patterns The Creational Pattern type is geared toward defining the preferred methods for creating new instances of objects. An example of this type is the Singleton Pattern. The Singleton Pattern can be used if an application only needs one instance of a class. In addition, this singular instance also needs to be accessible across an application. The benefit of the Singleton Pattern is that you control both instantiation and access using this pattern. The Structural Pattern type is a way to describe the hierarchy of objects and classes so that they can be consolidated into a larger structure. An example of this type is the Façade Pattern.  The Façade Pattern is used to define a base interface so that all other interfaces inherit from the parent interface. This can be used to simplify a number of similar object interactions into one single standard interface. The Behavioral Pattern Type deals with communication between objects. An example of this type is the State Design Pattern. The State Design Pattern enables objects to alter functionality and processing based on the internal state of the object at a given time.
