• It’s official – Red Gate is a great place to work!

  - by red@work

  At a glittering award ceremony last week, we found out that we’re officially the 14th best small company to work for in the whole of the UK! This is no mean feat, considering that about 1,000 companies enter the Sunday Times Top 100 best companies awards each year. Most of these are in the small companies category too. It's the fourth year in a row for us to be in the Top 100 list and we're tickled pink because the results are based on employee opinion. We’re particularly proud to be the best small company in Cambridge (in the whole of East Anglia, in fact) and the best small software development company in the entire UK. So how does it all work? Well, 90% of us took the time to answer over 70 questions on categories such as management, benefits, wellbeing, leadership, giving something back and what we think of Red Gate as a whole. It makes you think about every part of day to day working life and how you feel about it. Do you slightly or strongly agree or disagree that your manager motivates your to do your best every day, or that you have confidence in Red Gate's leaders, or that you’re not spending too much time working? It's great to see that we had one of the best scores in the country for the question "Do you think your company takes advantage of you?" We got particularly high scores for management, wellbeing and for giving something back too. A few of us got dressed up and headed to London for the awards; very excited about where we’d place but slightly nervous about having to get up on stage. There was a last minute hic up with a bow tie but the Managing Editor of the Sunday Times kindly stepped in to offer his assistance just before we had our official photo taken. We were nominated for two Special Recognition Awards. Despite not bringing them home this year, we're very proud to be nominated as there are only three nominations in each category. First we were up for the Training and Development award. Best Companies loved that we get together at lunchtimes to teach each other photography, cookery and French, as well as our book clubs and techie talks. And of course they liked our opportunities to go on training courses and to jet off to international conferences. Our other nomination was for the Wellbeing award. Best Companies loved our free food (and let’s face it, so do we). Porridge or bacon sandwiches for breakfast, a three course hot dinner, and free fruit and cereals all day long. If all that has an affect on the waistline then there are plenty of sporty activities for us all to get involved in, such as yoga, running or squash. Or if that’s not your thing then a relaxing massage helps us all to unwind every few months or so. The awards were hosted by news presenter Kate Silverton. She gave us a special mention during the ceremony for having great customer engagement as well as employee engagement, after we told her about Rodney Landrum (a Friend of Red Gate) tattooing our logo on his arm. We showed off our customised dinner jacket (thanks to Dom from Usability) with a flashing Red Gate logo on the back and she seemed suitability impressed. Back in the office the next day, we popped open the champagne and raised a glass to our success. Neil, our joint CEO, talked about how pleased he was with the award because it's based on the opinions of the people that count – us. You can read more about the Sunday Times awards here. By the way, we're still growing and are still hiring. If you’d like to keep up with our latest vacancies then why not follow us on Twitter at twitter.com/redgatecareers. Right now we're busy hiring in development, test, sales, product management, web development, and project management. Here's a link to our current job opportunities page – we'd love to hear from great people who are looking for a great place to work! After all, we're only great because of the people who work here.

• Implementing Service Level Agreements in Enterprise Manager 12c for Oracle Packaged Applications

  - by Anand Akela

  Contributed by Eunjoo Lee, Product Manager, Oracle Enterprise Manager. Service Level Management, or SLM, is a key tool in the proactive management of any Oracle Packaged Application (e.g., E-Business Suite, Siebel, PeopleSoft, JD Edwards E1, Fusion Apps, etc.). The benefits of SLM are that administrators can utilize representative Application transactions, which are constantly and automatically running behind the scenes, to verify that all of the key application and technology components of an Application are available and performing to expectations. A single transaction can verify the availability and performance of the underlying Application Tech Stack in a much more efficient manner than by monitoring the same underlying targets individually. In this article, we’ll be demonstrating SLM using Siebel Applications, but the same tools and processes apply to any of the Package Applications mentioned above. In this demonstration, we will log into the Siebel Application, navigate to the Contacts View, update a contact phone record, and then log-out. This transaction exposes availability and performance metrics of multiple Siebel Servers, multiple Components and Component Groups, and the Siebel Database - in a single unified manner. We can then monitor and manage these transactions like any other target in EM 12c, including placing pro-active alerts on them if the transaction is either unavailable or is not performing to required levels. The first step in the SLM process is recording the Siebel transaction. The following screenwatch demonstrates how to record Siebel transaction using an EM tool called “OpenScript”. A completed recording is called a “Synthetic Transaction”. The second step in the SLM process is uploading the Synthetic Transaction into EM 12c, and creating Generic Service Tests. We can create a Generic Service Test to execute our synthetic transactions at regular intervals to evaluate the performance of various business flows. As these transactions are running periodically, it is possible to monitor the performance of the Siebel Application by evaluating the performance of the synthetic transactions. The process of creating a Generic Service Test is detailed in the next screenwatch. EM 12c provides a guided workflow for all of the key creation steps, including configuring the Service Test, uploading of the Synthetic Test, determining the frequency of the Service Test, establishing beacons, and selecting performance and usage metrics, just to name a few. The third and final step in the SLM process is the creation of Service Level Agreements (SLA). Service Level Agreements allow Administrators to utilize the previously created Service Tests to specify expected service levels for Application availability, performance, and usage. SLAs can be created for different time periods and for different Service Tests. This last screenwatch demonstrates the process of creating an SLA, as well as highlights the Dashboards and Reports that Administrators can use to monitor Service Test results. Hopefully, this article provides you with a good start point for creating Service Level Agreements for your E-Business Suite, Siebel, PeopleSoft, JD Edwards E1, or Fusion Applications. Enterprise Manager Cloud Control 12c, with the Application Management Suites, represents a quick and easy way to implement Service Level Management capabilities at customer sites.

• Rotating WebLogic Server logs to avoid large files using WLST.

  - by adejuanc

  By default, when WebLogic Server instances are started in development mode, the server automatically renames (rotates) its local server log file as SERVER_NAME.log.n.  For the remainder of the server session, log messages accumulate in SERVER_NAME.log until the file grows to a size of 500 kilobytes.Each time the server log file reaches this size, the server renames the log file and creates a new SERVER_NAME.log to store new messages. By default, the rotated log files are numbered in order of creation filenamennnnn, where filename is the name configured for the log file. You can configure a server instance to include a time and date stamp in the file name of rotated log files; for example, server-name-%yyyy%-%mm%-%dd%-%hh%-%mm%.log.By default, when server instances are started in production mode, the server rotates its server log file whenever the file grows to 5000 kilobytes in size. It does not rotate the local server log file when the server is started. For more information about changing the mode in which a server starts, see Change to production mode in the Administration Console Online Help.You can change these default settings for log file rotation. For example, you can change the file size at which the server rotates the log file or you can configure a server to rotate log files based on a time interval. You can also specify the maximum number of rotated files that can accumulate. After the number of log files reaches this number, subsequent file rotations delete the oldest log file and create a new log file with the latest suffix.  Note: WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth. To Rotate via WLST : #invoke WLSTC:\>java weblogic.WLST#connect WLST to an Administration Serverawls:/offline> connect('username','password')#navigate to the ServerRuntime MBean hierarchywls:/mydomain/serverConfig> serverRuntime()wls:/mydomain/serverRuntime>ls()#navigate to the server LogRuntimeMBeanwls:/mydomain/serverRuntime> cd('LogRuntime/myserver')wls:/mydomain/serverRuntime/LogRuntime/myserver> ls()-r-- Name myserver-r-- Type LogRuntime-r-x forceLogRotation java.lang.Void :#force the immediate rotation of the server log filewls:/mydomain/serverRuntime/LogRuntime/myserver> cmo.forceLogRotation()wls:/mydomain/serverRuntime/LogRuntime/myserver> The server immediately rotates the file and prints the following message: <Mar 2, 2012 3:23:01 PM EST> <Info> <Log Management> <BEA-170017> <The log file C:\diablodomain\servers\myserver\logs\myserver.log will be rotated. Reopen the log file if tailing has stopped. This can happen on some platforms like Windows.><Mar 2, 2012 3:23:01 PM EST> <Info> <Log Management> <BEA-170018> <The log file has been rotated to C:\diablodomain\servers\myserver\logs\myserver.log00001. Log messages will continue to be logged in C:\diablodomain\servers\myserver\logs\myserver.log.> To specify the Location of the archived Log Files The following command specifies the directory location for the archived log files using the -Dweblogic.log.LogFileRotationDir Java startup option: java -Dweblogic.log.LogFileRotationDir=c:\foo-Dweblogic.management.username=installadministrator-Dweblogic.management.password=installadministrator weblogic.Server For more information read the following documentation ; Using the WebLogic Scripting Tool http://download.oracle.com/docs/cd/E13222_01/wls/docs103/config_scripting/using_WLST.html Configuring WebLogic Logging Services http://download.oracle.com/docs/cd/E12840_01/wls/docs103/logging/config_logs.html

• Top 5 Reasons to Invest in Enterprise 2.0 Technologies

  - by kellsey.ruppel(at)oracle.com

  In 2010, Oracle's portal, content management, and collaboration solutions evolved rapidly, supported by increasingly deep integrations across Oracle Fusion Middleware and the entire Oracle stack. In light of these developments, we asked Vince Casarez, vice president of Enterprise 2.0 product management, for his top five reasons to invest in Enterprise 2.0 (E2.0) technologies--including real-world examples of businesses already realizing the benefits of next-generation E2.0 technologies. 1. Provide a modern user experience As E2.0 technologies gain widespread adoption, customers and employees expect intuitive Web experiences that are both interactive and community-based. By partnering with Oracle, Alcatel-Lucent Enterprise Group is already making that happen. With 76,000 employees and operations in more than 100 countries, the company wanted a streamlined, personalized user experience with more relevant content in fewer clicks. Working with Oracle, they created a global support portal that supports personalization and integration with Oracle Business Intelligence Enterprise Edition and Oracle E-Business Suite--and drives collaboration with tools such as wikis, blogs, and forums. Learn more about Alcatel-Lucent Enterprise Group's Global Support Portal in this Webcast. 2. Improve productivity and collaboration As E2.0 technologies mature, Oracle anticipates companies moving beyond the idea of simply creating yet another Facebook-like destination for its employees, and instead shaping work environments around specific business tasks. After rapid growth--both organic and through acquisition--construction and infrastructure services leader Balfour Beatty found itself with multiple homegrown intranet sites with very minimal content-sharing capabilities. Today, thanks to Oracle WebCenter Suite, Oracle WebCenter Spaces, Oracle WebCenter Services, and Oracle Universal Content Management, Balfour Beatty is benefiting from collaborative workspaces, a central place to use and work with documents, and unified search across content. 3. Leverage business processes and applications Modern portals are now able to integrate users, content, and business processes in unprecedented ways. To take advantage of these new possibilities, leading dairy provider Land O'Lakes has implemented a fully integrated ERP solution together with Oracle's ECM platform. As a result, Land O'Lakes has been able to achieve better information management and compliance, increased adoption rates for enterprise tools, and increased business process efficiency thanks to more effective information sharing and collaboration. 4. Enhance customer and supplier relationships Companies have begun to move beyond the idea that E2.0 simply means enabling customer reviews or embedding chat functionality. They are taking E2.0 to the next level and providing interactive experiences for their customers. For example, to enhance customer and supplier relationships, Wind River, a global leader in device software optimization, successfully partnered with Oracle to: Integrate ERP and ECM content to provide customers the latest and most relevant support information for products they own Enable customers to personalize their support experience and receive updates regarding patches, application notes, and other relevant content Enable discussions, wikis, and blogs for more efficient collaboration 5. Increase business visibility and responsiveness By strategically embedding collaboration and communication tools into specific business contexts, companies significantly increase visibility into changing business conditions--and can respond much more agilely. Texas A&M University System--one of the largest systems of higher education in the U.S.--partnered with Oracle to create a unified repository that would enable the retrieval of research and grant data from disparate systems via an Enterprise 2.0 user interface. By enabling researchers to customize their own portals with easy-to-use tools, they have also been able to significantly reduce their reliance on the IT department. Learn how other Oracle customers are leveraging Enterprise 2.0 technologies.

• The Growing Importance of Network Virtualization

  - by user12608550

  The Growing Importance of Network Virtualization We often focus on server virtualization when we discuss cloud computing, but just as often we neglect to consider some of the critical implications of that technology. The ability to create virtual environments (or VEs [1]) means that we can create, destroy, activate and deactivate, and more importantly, MOVE them around within the cloud infrastructure. This elasticity and mobility has profound implications for how network services are defined, managed, and used to provide cloud services. It's not just servers that benefit from virtualization, it's the network as well. Network virtualization is becoming a hot topic, and not just for discussion but for companies like Oracle and others who have recently acquired net virtualization companies [2,3]. But even before this topic became so prominent, Solaris engineers were working on technologies in Solaris 11 to virtualize network services, known as Project Crossbow [4]. And why is network virtualization so important? Because old assumptions about network devices, topology, and management must be re-examined in light of the self-service, elasticity, and resource sharing requirements of cloud computing infrastructures. Static, hierarchical network designs, and inter-system traffic flows, need to be reconsidered and quite likely re-architected to take advantage of new features like virtual NICs and switches, bandwidth control, load balancing, and traffic isolation. For example, traditional multi-tier Web services (Web server, App server, DB server) that share net traffic over Ethernet wires can now be virtualized and hosted on shared-resource systems that communicate within a larger server at system bus speeds, increasing performance and reducing wired network traffic. And virtualized traffic flows can be monitored and adjusted as needed to optimize network performance for dynamically changing cloud workloads. Additionally, as VEs come and go and move around in the cloud, static network configuration methods cannot easily accommodate the routing and addressing flexibility that VE mobility implies; virtualizing the network itself is a requirement. Oracle Solaris 11 [5] includes key network virtualization technologies needed to implement cloud computing infrastructures. It includes features for the creation and management of virtual NICs and switches, and for the allocation and control of the traffic flows among VEs [6]. Additionally it allows for both sharing and dedication of hardware components to network tasks, such as allocating specific CPUs and vNICs to VEs, and even protocol-specific management of traffic. So, have a look at your current network topology and management practices in view of evolving cloud computing technologies. And don't simply duplicate the physical architecture of servers and connections in a virtualized environment…rethink the traffic flows among VEs and how they can be optimized using Oracle Solaris 11 and other Oracle products and services. [1] I use the term "virtual environment" or VE here instead of the more commonly used "virtual machine" or VM, because not all virtualized operating system environments are full OS kernels under the control of a hypervisor…in other words, not all VEs are VMs. In particular, VEs include Oracle Solaris zones, as well as SPARC VMs (previously called LDoms), and x86-based Solaris and Linux VMs running under hypervisors such as OEL, Xen, KVM, or VMware. [2] Oracle follows VMware into network virtualization space with Xsigo purchase; http://www.mercurynews.com/business/ci_21191001/oracle-follows-vmware-into-network-virtualization-space-xsigo [3] Oracle Buys Xsigo; http://www.oracle.com/us/corporate/press/1721421 [4] Oracle Solaris 11 Networking Virtualization Technology, http://www.oracle.com/technetwork/server-storage/solaris11/technologies/networkvirtualization-312278.html [5] Oracle Solaris 11; http://www.oracle.com/us/products/servers-storage/solaris/solaris11/overview/index.html [6] For example, the Solaris 11 'dladm' command can be used to limit the bandwidth of a virtual NIC, as follows: dladm create-vnic -l net0 -p maxbw=100M vnic0

• The Minimalist Approach to Content Governance - Request Phase

  - by Kellsey Ruppel

  Originally posted by John Brunswick. For each project, regardless of size, it is critical to understand the required ownership, business purpose, prerequisite education / resources needed to execute and success criteria around it. Without doing this, there is no way to get a handle on the content life-cyle, resulting in a mass of orphaned material. This lowers the quality of end user experiences.     The good news is that by using a simple process in this request phase - we will not have to revisit this phase unless something drastic changes in the project. For each of the elements mentioned above in this stage, the why, how (technically focused) and impact are outlined with the intent of providing the most value to a small team. 1. Ownership Why - Without ownership information it will not be possible to track and manage any of the content and take advantage of many features of enterprise content management technology. To hedge against this, we need to ensure that both a individual and their group or department within the organization are associated with the content. How - Apply metadata that indicates the owner and department or group that has responsibility for the content. Impact - It is possible to keep the content system optimized by running native reports against the meta-data and acting on them based on what has been outlined for success criteria. This will maximize end user experience, as content will be faster to locate and more relevant to the user by virtue of working through a smaller collection. 2. Business Purpose Why - This simple step will weed out requests that have tepid justification, as users will most likely not spend the effort to request resources if they do not have a real need. How - Use a simple online form to collect and workflow the request to management native to the content system. Impact - Minimizes the amount user generated content that is of low value to the organization. 3. Prerequisite Education Resources Needed Why - If a project cannot be properly staffed the probability of its success is going to be low. By outlining the resources needed - in both skill set and duration - it will cause the requesting party to think critically about the commitment needed to complete their project and what gap must be closed with regard to education of those resources. How - In the simple request form outlined above, resources and a commitment to fulfilling any needed education should be included with a brief acceptance clause that outlines the requesting party's commitment. Impact - This stage acts as a formal commitment to ensuring that resources are able to execute on the vision for the project. 4. Success Criteria Why - Similar to the business purpose, this is a key element in helping to determine if the project and its respective content should continue to exist if it does not meet its intended goal. How - Set a review point for the project content that will check the progress against the originally outlined success criteria and then determine the fate of the content. This can even include logic that will tell the content system to remove items that have not been opened by any users in X amount of time. Impact - This ensures that projects and their contents do not live past their useful lifespans. Just as with orphaned content, non-relevant information will slow user's access to relevant materials for the jobs. Request Phase Summary With a simple form that outlines the ownership of a project and its content, business purpose, education and resources, along with success criteria, we can ensure that an enterprise content management system will stay clean and relevant to end users - allowing it to deliver the most value possible. The key here is to make it straightforward to make the request and let the content management technology manage as much as possible through metadata, retention policies and workflow. Doing these basic steps will allow project content to get off to a great start in the enterprise! Stay tuned for the next installment - the "Create Phase" - covering security access and workflow involved in content creation, enabling a practical layer of governance over our enterprise content repository.

and web service is up and running. I'm using Netbeans IDE in Ubuntu 12.04 to build and deploy the application and I couldn't figure out what is the issue here. I guess its about spring and jboss because its working in glassfish smoothly. Please help me to solve this issue. Thanks all in advance.

• How do I repair the corrupted files found by sfc /scannow? "Windows Resource Protection found corrupt files but was unable to fix some of them."

  - by galacticninja

  After running chkdsk C: /F /R and finding out that my hard disk has 24 KB in bad sectors (log is posted below), I decided to run Windows 7's System File Checker utility (sfc /scannow). SFC showed the ff. message after I ran it: "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log." Since the CBS.log file is too large, I ran findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" (as per Microsoft's KB 928228 article) to only get the log text pertaining to the corrupt files. (log is also posted below) How do I troubleshoot and repair the corrupted files mentioned by sfc /scannow?

• MySQL query, 2 similar servers, 2 minute difference in execution times

  - by mr12086

  I had a similar question on stack overflow, but it seems to be more server/mysql setup related than coding. The queries below all execute instantly on our development server where as they can take upto 2 minutes 20 seconds. The query execution time seems to be affected by home ambiguous the LIKE string's are. If they closely match a country that has few matches it will take less time, and if you use something like 'ge' for germany - it will take longer to execute. But this doesn't always work out like that, at times its quite erratic. Sending data appears to be the culprit but why and what does that mean. Also memory on production looks to be quite low (free memory)?

• DataContractSerializer and deserializing web service response types

  - by matra

  Hi, I am using calling web services and using WCF generated service-reference on the client. I have saved XML responses that are received from test service to disk (without SOAP envelope and body tags) I would like to load them from disk and create objects from them. Lets' take the following method from my web service: SomeMethodResponse SomeMethod(SomeMethodRequest req) I manually (through SOAP UI) save the response to disk to file, Sample response: < SomeMethodResponse xmlns="http://myNamespace"> <SomeMember1>value</SomeMember1> </SomeMethodResponse xmlns="http://myNamespace"> Then I try to deserialize the object from file using: DataContractSerializer dcs = new DataContractSerializer(typeof(SomeMethodResponse)) This fails – the serializer complains with the error, that it is expecting element in namespace 'http://schemas.datacontract.org/2004/07', but found element in 'http://myNamespace'. Question: Why does the DataContractSerializer not use the namespace, that is declared on SomeMethodResponseType with XmlTypeAttribute(Namespace="http://myNamespace")? I can work around this by explicitly providing the namespace and the root element to DataContractSerializer constructor. But then it fails with message similar to: Error in line X position Y (last line of the XMLdocument). 'EndElement' 'SomeMethodResponse from namespace 'httpmyNapespace’ is not expected. Expecting element 'someNameField'. SomeName is an element in the XSD that web service is using. It is also a property on the SomeMethodResponse type, backed by the private field called someNameField. It looks like DataContractSerializer is trying to deserialize the fields in addition to properties. How can I deserailize XML that I have saved from disk and get back the object of same type that SomeMethod is returning? Thanks, Matra

• Visual studio 2010 setup project problem.

  - by Guru

  Hi there, I've made an application that uses .NET framework 3.5 SP1 and SQL Server 2008 Express. Application is fine and now i'm going to to make a setup project for this. When I first build my setup it was fine as all the prerequisites were not included in setup. But I want my setup to install .NET 3.5 SP1 and SQL SERVER 2008 Express also. So for this I've changed the options in setup project's properties from "Download prerequisites from following location" to "Download prerequisites from the same location as my application". In addition to that I've also checked the options above like .NET 3.5 SP1 and SQL Server 2008 Express etc. After doing all this I build my project again. This time I'm Getting 57 Errors. Error 1 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'DotNetFX35SP1\dotNetFX20\aspnet.msp' in item '.NET Framework 3.5 SP1' can not be located on disk. See Help for more information. D:\MindStrike Setup\MindStrike Setup.vdproj MindStrike Setup Error 2 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'DotNetFX35SP1\dotNetFX20\aspnet_64.msp' in item '.NET Framework 3.5 SP1' can not be located on disk.

• Software development metrics and reporting

  - by David M

  I've had some interesting conversations recently about software development metrics, in particular how they can be used in a reasonably large organisation to help development teams work better. I know there have been Stack Overflow questions about which metrics are good to use - like this one, but my question is more about which metrics are useful to which stakeholders, and at what level of aggregation. As an example, my view is that code coverage is a useful metric in the following ways (and maybe others): For a team's own internal use when combined with other measurements. For facilitating/enabling/mentoring teams, where it might be instructive when considered on a team-by-team basis as a trend (e.g. if team A and B have coverage this month of 75 and 50, I'd be more concerned with team A than B if the previous month they'd had 80 and 40). For senior management when presented as an aggregated statistic across a number of teams or a whole department. But I don't think it's useful for senior management to see this on a team-by-team basis, as this encourages artifical attempts to bolster coverage with tests that merely exercise, rather than test, code. I'm in an organisation with a couple of levels in its management hierarchy, but where the vast majority of managers are technically minded and able (with many still getting their hands dirty). Some of the development teams are leading the way in driving towards agile development practices, but others lag, and there is now a serious mandate from the top for this to be the way the organisation works. A couple of us are starting a programme to encourage this. In this sort of an organisation, what sort of metrics do you think are useful, to whom, why, and at what level of aggregation? I don't want people to feel their performance is being assessed based on a metric that they can artificially influence; at the same time, the senior management are going to want some sort of evidence that progress is being made. What advice or caveats can you provide based on experience in your own organisations? EDIT We are definitely wanting to use metrics as a tool for organisational improvement not as a tool for individual performance measurement.

• Out of Core Implementation of a Quadtree

  - by Nima

  Hi, I am trying to build a Quadtree data structure(or let's just say a tree) on the secondary memory(Hard Disk). I have a C++ program to do so and I use fopen to create the files. Also, I am using tesseral coding to store each cell in a file named with its corresponding code to store it on the disk in one directory. The problem is that after creating about 1,100 files, fopen just returns NULL and stops creating new files. I can create further files manually in that directory, but using C++ it can not create any further files. I know about max limit of inode on ext3 filesystem which is (from Wikipedia) 32,000 but mine is way less than that, also note that I can create files manually on the disk; just not through fopen. Also, I really appreciate any idea regarding the best way to store a very dynamic quadtree on disk(I need the nodes to be in separate files and the quadtree might have a depth of 50). Using nested directories is one idea, but I think it will slow down the performance because of following the links on the filesystem to access the file. Thanks, Nima

• Problem using custom HttpHandler to process requests for both .aspx and non-extension pages in IIS7

  - by Noel

  I am trying to process both ".aspx" and non-extension page requests (i.e. both contact.aspx and /contact/) using a custom HttpHandler in IIS7. My handler works just fine in either one case or the other, but as soon as I try to process both cases, it only works for one. Please see Handlers snippet from my web.config below: If i keep only mapping to "*.aspx" then all .aspx requests are processed correctly, but obviously extensionless requests won't work: <add name="AllPages.ASPX" path="*.aspx" verb="*" type="Test.PageHandlerFactory, Test" preCondition="" /> If i change the mapping to "*" then all extensionless requests are processed correctly, but ".aspx" requests that should still be handled by this handler stop working. Note that i added the StaticFiles entry in order to process files that are on disk like images, css, js, etc. <add name="WebResource" path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" /> <add name="StaticFiles" verb="GET,HEAD" path="*.*" type="System.Web.StaticFileHandler" resourceType="File" /> <add name="AllPages" path="*" verb="*" type="Test.PageHandlerFactory, Test" preCondition="" /> The crazy thing is that when i load an ".aspx" request (with the 2nd configuration shown) IIS7 gives a 404 not found error. The error also says that the request is processed by the StaticFiles handler. But I made sure to add resourceType="File" to the StaticFileHandler in order to avoid this. According to MS this means the request is only for "physical files on disk". Am i misreading/interpreting the "on disk" part? My .aspx file isn't on disk, that's why i want to use the handler in the first place.

• SQL Server Clustered Index: (Physical) Data Page Order

  - by scherand

  I am struggling understanding what a clustered index in SQL Server 2005 is. I read the MSDN article Clustered Index Structures (among other things) but I am still unsure if I understand it correctly. The (main) question is: what happens if I insert a row (with a "low" key) into a table with a clustered index? The above mentioned MSDN article states: The pages in the data chain and the rows in them are ordered on the value of the clustered index key. And Using Clustered Indexes for example states: For example, if a record is added to the table that is close to the beginning of the sequentially ordered list, any records in the table after that record will need to shift to allow the record to be inserted. Does this mean that if I insert a row with a very "low" key into a table that already contains a gazillion rows literally all rows are physically shifted on disk? I cannot believe that. This would take ages, no? Or is it rather (as I suspect) that there are two scenarios depending on how "full" the first data page is. A) If the page has enough free space to accommodate the record it is placed into the existing data page and data might be (physically) reordered within that page. B) If the page does not have enough free space for the record a new data page would be created (anywhere on the disk!) and "linked" to the front of the leaf level of the B-Tree? This would then mean the "physical order" of the data is restricted to the "page level" (i.e. within a data page) but not to the pages residing on consecutive blocks on the physical hard drive. The data pages are then just linked together in the correct order. Or formulated in an alternative way: if SQL Server needs to read the first N rows of a table that has a clustered index it can read data pages sequentially (following the links) but these pages are not (necessarily) block wise in sequence on disk (so the disk head has to move "randomly"). How close am I? :)

• loaded resources looks ugly

  - by Xaver

  I have the TreeView class using in my project. I use icons for it.First i load icons so: ImageList^ il = gcnew ImageList(); il->Images->Add(Image::FromFile("DISK.ico")); il->Images->Add(Image::FromFile("FILE.ico")); il->Images->Add(Image::FromFile("FOLDER.ico")); treeView1->ImageList = il; All was good. But i dont like that if i delete my icons from directory of project. there is error in my project. I decide to add icons in .resx file. Now icons loading look so: ImageList^ il = gcnew ImageList(); Resources::ResourceManager^ resourceManager = gcnew Resources::ResourceManager ("FilesSaver.Form1", GetType()->Assembly); Object^ disk = resourceManager->GetObject("DISK"); il->Images->Add(reinterpret_cast<Image^>(disk)); Object^ file = resourceManager->GetObject("FILE"); il->Images->Add(reinterpret_cast<Image^>(file)); Object^ folder = resourceManager->GetObject("FOLDER"); il->Images->Add(reinterpret_cast<Image^>(folder)); treeView1->ImageList = il; And why icons in the TreeView looks ugly (they look lighter and have a big black border). Why did this happen?

• Fastest PNG decoder for .NET

  - by sboisse

  Our web server needs to process many compositions of large images together before sending the results to web clients. This process is performance critical because the server can receive several thousands of requests per hour. Right now our solution loads PNG files (around 1MB each) from the HD and sends them to the video card so the composition is done on the GPU. We first tried loading our images using the PNG decoder exposed by the XNA API. We saw the performance was not too good. To understand if the problem was loading from the HD or the decoding of the PNG, we modified that by loading the file in a memory stream, and then sending that memory stream to the .NET PNG decoder. The difference of performance using XNA or using System.Windows.Media.Imaging.PngBitmapDecoder class is not significant. We roughly get the same levels of performance. Our benchmarks show the following performance results: Load images from disk: 37.76ms 1% Decode PNGs: 2816.97ms 77% Load images on Video Hardware: 196.67ms 5% Composition: 87.80ms 2% Get composition result from Video Hardware: 166.21ms 5% Encode to PNG: 318.13ms 9% Store to disk: 3.96ms 0% Clean up: 53.00ms 1% Total: 3680.50ms 100% From these results we see that the slowest parts are when decoding the PNG. So we are wondering if there wouldn't be a PNG decoder we could use that would allow us to reduce the PNG decoding time. We also considered keeping the images uncompressed on the hard disk, but then each image would be 10MB in size instead of 1MB and since there are several tens of thousands of these images stored on the hard disk, it is not possible to store them all without compression.

• Why this code generates different numbers?

  - by frbry

  Hello, I have this function that creates a unique number for hard-disk and CPU combination. DWORD hw_hash() { char drv[4]; char szNameBuffer[256]; DWORD dwHddUnique; DWORD dwProcessorUnique; DWORD dwUniqueKey; char *sysDrive = getenv ("SystemDrive"); strcpy(drv, sysDrive); drv[2] = '\\'; drv[3] = 0; GetVolumeInformation(drv, szNameBuffer, 256, &dwHddUnique, NULL, NULL, NULL, NULL); SYSTEM_INFO si; GetSystemInfo(&si); dwProcessorUnique = si.dwProcessorType + si.wProcessorArchitecture + si.wProcessorRevision; dwUniqueKey = dwProcessorUnique + dwHddUnique; return dwUniqueKey; } It returns different numbers if I format my hard-disk and install a new Windows. Any ideas, why? Thank you. Edit: OK, Got it: This function returns the volume serial number that the operating system assigns when a hard disk is formatted. To programmatically obtain the hard disk's serial number that the manufacturer assigns, use the Windows Management Instrumentation (WMI) Win32_PhysicalMedia property SerialNumber. I should do more research before posting my problems online. Sorry to bother you, let's keep this here in case anybody else can need it.
