  • Windows 8 / IIS 8 Concurrent Requests Limit

    - by OWScott
    IIS 8 on Windows Server 2012 doesn’t have any fixed concurrent request limit, apart from whatever limit would be reached when resources are maxed. However, the client version of IIS 8, which is on Windows 8, does have a concurrent connection request limitation to limit high traffic production uses on a client edition of Windows. Starting with IIS 7 (Windows Vista), the behavior changed from previous versions.  In previous client versions of IIS, excess requests would throw a 403.9 error message (Access Forbidden: Too many users are connected.).  Instead, Windows Vista, 7 and 8 queue excessive requests so that they will be handled gracefully, although there is a maximum number of requests that will be processed simultaneously. Thomas Deml provided a concurrent request chart for Windows Vista many years ago, but I have been unable to find an equivalent chart for Windows 8 so I asked Wade Hilmo from the IIS team what the limits are.  Since this is controlled not by the IIS team itself but rather from the Windows licensing team, he asked around and found the authoritative answer, which I’ll provide below. Windows 8 – IIS 8 Concurrent Requests Limit Windows 8 3 Windows 8 Professional 10 Windows RT N/A since IIS does not run on Windows RT Windows 7 – IIS 7.5 Concurrent Requests Limit Windows 7 Home Starter 1 Windows 7 Basic 1 Windows 7 Premium 3 Windows 7 Ultimate, Professional, Enterprise 10 Windows Vista – IIS 7 Concurrent Requests Limit Windows Vista Home Basic (IIS process activation and HTTP processing only) 3 Windows Vista Home Premium 3 Windows Vista Ultimate, Professional 10 Windows Server 2003, Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012 allow an unlimited amount of simultaneously requests.

  • What’s New In Microsoft Security Essentials 2.0 And How To Upgrade To 2.0

    - by Gopinath
    Since Microsoft released Microsoft Security Essentials(MSE) couple of years ago, I stopped worrying about antivirus programs on all my Windows PCs. MSE is just awesome and it’s the best free antivirus available in the market. Microsoft released version 2.0 of MSE yesterday with enhanced security features and more love for Windows users. New features introduced in this version are New protection engine - Heuristic scanning engine is introduced to bump the virus detection and cleaning mechanism. Network inspection system to monitor network traffic as we browse and protects us from malicious scripts and programs. Better integration with Windows Firewall With this upgrade, MSE is irresistible antivirus application to have on every Windows PC. How To Upgrade MSE 1.0 to 2.0 Generally upgrading Microsoft applications are kids play. All one would require to upgrade is to go to Help->Check for upgrades menu option and follow the wizard to complete upgrade process. Microsoft Security Essentials 1.0 to 2.0 upgrade is also expected to be this way, but somehow it’s not working for me in India. May be I guess, MSE 2.0 is not released for Indian users. What ever may be the reason, it’s very easy to upgrade MSE 1.0 to 2.0  manually. Just download the installer from Microsoft(link given below) and run the installer. Choose Upgrade option when the installer is executing to have MSE 2.0 installed on your PC. MSE 2.0 Download Link You can download Microsoft Security Essentials 2.0 at Microsoft Download Center.

  • 2 way SSL between SOA and OSB

    - by Johnny Shum
    If you have a need to use 2 way SSL between SOA composite and external partner links, you can follow these steps. Create the identity keystores, trust keystores, and server certificates. Setup keystores and SSL on WebLogic Setup server to use 2 way SSL Configure your SOA composite's partner link to use 2 way SSL Configure SOA engine two ways SSL In this case,  I use SOA and OSB for the test.  I started with a separate OSB and SOA domains.  I deployed two soap based proxies on OSB and two composites on SOA.  In SOA, one composite invokes a OSB proxy service, the other is invoked by the OSB.  Similarly,  in OSB,  one proxy invokes a SOA composite and the other is invoked by SOA. 1. Create the identity keystores, trust keystores and the server certificates Since this is a development environment, I use JDK's keytool to create the stores and use self signing certificate.  For production environment, you should use certificates from a trusted certificate authority like Verisign.    I created a script below to show what is needed in this step.  The only requirement is when creating the SOA identity certificate, you MUST use the alias mykey. STOREPASS=welcome1KEYPASS=welcome1# generate identity keystore for soa and osb.  Note: For SOA, you MUST use alias mykeyecho "creating stores"keytool -genkey -alias mykey -keyalg "RSA" -sigalg "SHA1withRSA" -dname "CN=soa, C=US" -keystore soa-default-keystore.jks -storepass $STOREPASS -keypass $KEYPASS keytool -genkey -alias osbkey -keyalg "RSA" -sigalg "SHA1withRSA" -dname "CN=osb, C=US" -keystore osb-default-keystore.jks -storepass $STOREPASS -keypass $KEYPASS# listing keystore contentsecho "listing stores contents"keytool -list -alias mykey -keystore soa-default-keystore.jks -storepass $STOREPASSkeytool -list -alias osbkey -keystore osb-default-keystore.jks -storepass $STOREPASS# exporting certs from storesecho "export certs from  stores"keytool -exportcert -alias mykey -keystore soa-default-keystore.jks -storepass $STOREPASS -file soacert.derkeytool -exportcert -alias osbkey -keystore osb-default-keystore.jks -storepass $STOREPASS -file osbcert.der # import certs to trust storesecho "import certs"keytool -importcert -alias osbkey -keystore soa-trust-keystore.jks -storepass $STOREPASS -file osbcert.der -keypass $KEYPASSkeytool -importcert -alias mykey -keystore osb-trust-keystore.jks -storepass $STOREPASS -file soacert.der  -keypass $KEYPASS SOA suite uses the JDK's SSL implementation for outbound traffic instead of the WebLogic's implementation.  You will need to import the partner's public cert into the trusted keystore used by SOA.  The default trusted keystore for SOA is DemoTrust.jks and it is located in $MW_HOME/wlserver_10.3/server/lib.   (This is set in the startup script -Djavax.net.ssl.trustStore).   If you use your own trusted keystore, then you will need to import it into your own trusted keystore. keytool -importcert -alias osbkey -keystore $MW_HOME/wlserver_10.3/server/lib/DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase  -file osbcert.der -keypass $KEYPASS If you do not perform this step, you will encounter this exception in runtime when SOA invokes OSB service using 2 way SSL Message send failed: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target  2.  Setup keystores and SSL on WebLogic First, you will need to login to the WebLogic console, navigate to the server's configuration->Keystore's tab.   Change the Keystores type to Custom Identity and Custom Trust and enter the rest of the fields. Then you navigate to the SSL tab, enter the fields in the identity section and expand the Advanced section.  Since I am using self signing cert on my VM enviornment, I disabled Hostname verification.  In real production system, this should not be the case.   I also enabled the option "Use Server Certs", so that the application uses the server cert to initiate https traffic (it is important to enable this in OSB). Last, you enable SSL listening port in the Server's configuration->General tab. 3.  Setup server to use 2 way SSL If you follow the screen shot in previous step, you can see in the Server->Configuration->SSL->Advanced section, there is an option for Two Way Client Cert Behavior,  you should set this to Client Certs Requested and Enforced. Repeat step 2 and 3 done on OSB.  After all these configurations,  you have to restart all the servers. 4.  Configure your SOA composite's partner link to use 2 way SSL You do this by modifying the composite.xml in your project, locate the partner's link reference and add the property oracle.soa.two.way.ssl.enabled.   <reference name="callosb" ui:wsdlLocation="helloword.wsdl">    <interface.wsdl interface="http://www.examples.com/wsdl/HelloService.wsdl#wsdl.interface(Hello_PortType)"/>    <binding.ws port="http://www.examples.com/wsdl/HelloService.wsdl#wsdl.endpoint(Hello_Service/Hello_Port)"                location="helloword.wsdl" soapVersion="1.1">      <property name="weblogic.wsee.wsat.transaction.flowOption"                type="xs:string" many="false">WSDLDriven</property>   <property name="oracle.soa.two.way.ssl.enabled">true</property>    </binding.ws>  </reference> In OSB, you should have checked the HTTPS required flag in the proxy's transport configuration.  After this,  rebuilt the composite jar file and ready to deploy in the EM console later. 5.  Configure SOA engine two ways SSL Oracle SOA Suite uses both Oracle WebLogic Server and Sun Secure Socket Layer (SSL) stacks for two-way SSL configurations. For the inbound web service bindings, Oracle SOA Suite uses the Oracle WebLogic Server infrastructure and, therefore, the Oracle WebLogic Server libraries for SSL.  This is already done by step 2 and 3 in the previous section. For the outbound web service bindings, Oracle SOA Suite uses JRF HttpClient and, therefore, the Sun JDK libraries for SSL.  You do this by configuring the SOA Engine in the Enterprise Manager Console, select soa-infra->SOA Administration->Common Properties Then click at the link at the bottom of the page:  "More SOA Infra Advances Infrastructure Configuration Properties" and then enter the full path of soa identity keystore in the value field of the KeyStoreLocation attribute.  Click Apply and Return then navigate to the domain->security->credential. Here, you provide the password to the keystore.  Note: the alias of the certficate must be mykey as described in step 1, so you only need to provide the password to the identity keystore.   You accomplish this by: Click Create Map In the Map Name field, enter SOA, and click OK Click Create Key Enter the following details where the password is the password for the SOA identity keystore. 6.  Test and Trouble Shooting Once the setup is complete and server restarted, you can deploy the composite in the EM console and test it.  In case of error,  you can read the server log file to determine the cause of the error.  For example, If you have not setup step 5 and test 2 way SSL, you will see this in the log when invoking OSB from BPEL: java.lang.Exception: oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException: oracle.fabric.common.FabricInvocationException: Unable to access the following endpoint(s): https://localhost.localdomain:7002/default/helloword ####<Sep 22, 2012 2:07:37 PM CDT> <Error> <oracle.soa.bpel.engine.ws> <rhel55> <AdminServer> <[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <BEA1-0AFDAEF20610F8FD89C5> ............ <11d1def534ea1be0:-4034173:139ef56d9f0:-8000-00000000000002ec> <1348340857956> <BEA-000000> <got FabricInvocationException sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target If you have not enable WebLogic SSL to use server certificate in the console and invoke SOA composite from OSB using two ways SSL, you will see this error: ####<Sep 22, 2012 2:07:37 PM CDT> <Warning> <Security> <rhel55> <AdminServer> <[ACTIVE] ExecuteThread: '6' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <11d1def534ea1be0:-51f5c76a:139ef5e1e1a:-8000-00000000000000e2> <1348340857776> <BEA-090485> <CERTIFICATE_UNKNOWN alert was received from localhost.localdomain - 127.0.0.1.

  • Step Aside Google

    - by David Dorf
    Step aside Google. While search will always be a huge part of the web, I can see a day in the not-too-distance future where search takes a backseat to the social graph. Links between pages will give way to relationships between people, including context like location. What does this mean for retail? It means your e-commerce strategy will slowly transition to an f-commerce strategy. Remember when a large portion of the online population was held captive inside the walls of AOL? All the commercials listed an AOL keyword, not a web address because that's where the majority of people surfed. Now, people are spending a huge amount of time in Facebook (despite Betty White's proclamation that its a big waste of time). According to Facebook, users spend 500 billion minutes per month on the site. Selling products where consumers are spending their time makes sense. The power of Like and Share are the most effective approach to marketing. More and more stores are popping up on Facebook, and soon they will be the front-end to e-commerce systems. As sites adopt the Facebook Open Graph API, users will have a harder time distinguishing the open web from their Facebook experience, including shopping. Of course e-commerce sites won't go away, but a large portion of their traffic will emanate from Facebook and in some cases Facebook will act as the front-end for the web store. Ignore Facebook Open Graph at your peril. In a Mashable article, Mitchell Harper made several predictions about how e-commerce will change based on Facebook. His five points are not far-fetched at all, so we need to watch this space carefully.

If you doubt this an article on SitePoint discussing ’Page Speed and Business Metrics’ may change your mind. http://www.sitepoint.com/page-speed-business-metrics/ Here are some of the figures it quotes: Walmart – saw a 2% increase in conversions for every second of improvement in page load time. Put another way, accumulated growth of revenues went up 1% for every 100 milliseconds of load time improvement. Yahoo – for every 400 milliseconds of improvement, the site traffic increased by 9%. The bottom line is that if people have to wait more than a few seconds for a page to fully render, particularly on a mobile device, they’ll probably go elsewhere.

  • Is OpenTK Dead?

    - by ashes999
    Looking at OpenTK, I notice some disturbing signs: The last news item was posted on December 31st, 2010 The main forum gets about one post a day On SourceForge, the last nightly build was in March, and the last release was 2010. Does OpenTK exist anymore, or is it abandonware now? Edit: Some people have expressed concern at my use of "ambiguous" and "loaded terms" like "dead," "abandonware," and others. What I'm asking is this: software projects comprise of many pieces: The actual software project (such as OpenTK) A group of people who maintain the software (project leads, core developers) Some vehicle by which users can find and consume the latest versions (such as releasing daily builds) A community (can I ask questions about it? Get answers?) Updates (are there new features? New releases? Active development? A roadmap?) Some projects have all of these things. Most have a few. Some have nothing, other than maybe the actual software project itself. Is OpenTK one of these? Because it seems like: The actual software project is stable The maintainers don't contribute to it anymore There are no more latest versions (daily builds), not since 2010 (2+ years) The community is very low-traffic (nobody is asking/answering questions, who is actually using this anyway?) There are no updates since 2010

  • index.html redirecting to cgi-sys/defaultwebpage.cgi

    - by Andrew De Forest
    This problem has been persisting over the last couple of days. I thought I fixed it Friday only to get in on Monday morning and see that cPanel is still giving me issues. On Friday, all incoming traffic to my index.html page were being redirected to cgi-sys/defaultwebpage.cgi. Upon further investigation, I found that my entire index.html code had been overwritten and contained only a single meta tag, which was causing the aforementioned redirect. I re-uploaded the original index page and overwrote the one that was causing the redirects and it seemed to have fixed the problem. Fast forward to Monday. The problem began happening again and I took the same steps as before to fix it, but now I'm wondering how to permanently stop this from happening. From what I've found, it's related to cPanel. I personally did not make any changes to the server, but there are a few people with access who might have. I'm on a VPS with my own dedicated IP address. I've been hosting fine for a few months without this problem. The server is runs a traditional LAMP stack.

  • CRM@Oracle Series: Web Marketing Integration

    - by tony.berk
    Who is visiting your website? How did they get there? Was it from a search engine? Email campaign? Are they downloading whitepapers, datasheets, presentations, software? Are they interested in attending one of your marketing events? Are you capturing these leads or which marketing campaign generated the lead? There are a lot of questions related to traffic on a website, and the answers to those questions can be found in your CRM system. Visitors who download marketing collateral are potential leads, so it is important to capture who they are, how they got there, where they went on the website and what they are looking for. Today's CRM@Oracle slidecast discusses how Oracle uses Siebel CRM to plan and execute marketing campaigns on our website, www.oracle.com, and capture the key information about who is downloading content or interested in attending one of our marketing events. The responses are captured, qualified, and if appropriate, a lead is generated. It all happens in Siebel CRM.

  • /users/tags should contain scores

    - by Sean Patrick Floyd
    I am implementing some simple JavaScript/bookmarklet based apps that show some reputation info, including the score in the User's top tags (roughly based on this previous bookmarklet of mine). Now I can get a user's top tags (using the API), and I can also get the per-tag score if the user is logged in, by dynamically parsing the tag's top users page. But it costs me one AJAX request per tag and I have to download 10+k to extract a single numeric value. It would save a lot of traffic if the tags in <api>/users/<userid>/tags had a score field. The data seems to be there, after all the top users pages use it, so it would just be a question of exposing the data. Suggested structure: "tags": [ { "name": { "description": "name of the tag", "values": "string", "optional": false, "suggested_buffer_size": 25 }, "score": { "description": "tag score, sum of up votes for answers on non-wiki questions", "values": "32-bit signed integer", "optional": false }, "count": { "description": "tag count, exact meaning depends on context", "values": "32-bit signed integer", "optional": false }, "restricted_to": { "description": "user types that can make use of this tag, lack of this field indicates it is useable by all", "values": "one of anonymous, unregistered, registered, or moderator", "optional": true }, "fulfills_required": { "description": "indicates whether this tag is one of those that is required to be on a post", "values": "boolean", "optional": false }, "user_id": { "description": "user associated with this tag, depends on context", "values": "32-bit signed integer", "optional": true } } ]

  • What is recommended minimum object size for gzip performance benefits?

    - by utt73
    I'm working on improving page speed display times, and one of the methods is to gzip content from the webserver. Google recommends: Note that gzipping is only beneficial for larger resources. Due to the overhead and latency of compression and decompression, you should only gzip files above a certain size threshold; we recommend a minimum range between 150 and 1000 bytes. Gzipping files below 150 bytes can actually make them larger. We serve our content through Akamai, using their network for a proxy and CDN. What they've told me: Following up on your question regarding what is the minimum size Akamai will compress the requested object when sending it to the end user: The minimum size is 860 bytes. My reply: What is the reason(s) for why Akamai's minimum size is 860 bytes? And why, for example, is this not the case for files Akamai serves for facebook? (see below) Google recommends to gzip more agressively. And that seems appropriate on our site where the most frequent hits, by far, are AJAX calls that are <860 bytes. Akamai's response: The reasons 860 bytes is the minimum size for compression is twofold: (1) The overhead of compressing an object under 860 bytes outweighs performance gain. (2) Objects under 860 bytes can be transmitted via a single packet anyway, so there isn't a compelling reason to compress them. So I'm here for some fact checking. Is the 860 byte limit due to packet size the end of this reasoning? Why would high traffic sites push this down to the 150 byte limit... just to save on bandwidth costs (since CDNs base their charges on bandwith offloaded from origin), or is there a performance gain in doing so?

  • My software is hosted on a "bad" website. Can I do anything about it?

    - by Abluescarab
    The software I've created is hosted on what you could call a "bad" website. It's hard to explain, so I'll just provide an example. I've made a free password generator. This, along with most of my other FREE software, is available on this website. This is their description of my software: Platform: 7/7 x64/Windows 2K/XP/2003/Vista Size: 61.6 Mb License: Trial File Type: .7z Last Updated: June 4th, 2011, 15:38 UTC Avarage Download Speed: 6226 Kb/s Last Week Downloads: 476 Toatal Downloads: 24908 Not only is the size completely skewed, it is not trial software, it's free software. The thing is that it's not the description I'm worried about--it's the download links. The website is a scam website. They apparently link to "cracks" and "keygens", but not only is that in itself illegal, they actually link to fake download websites that give you viruses and charge your credit card. Just to list things that are wrong with this website: they claim all software is paid software then offer downloads for keygens and cracks; they fake all details about the program and any program reviews and ratings; they and the downloads site they link to are probably run by the same person, so they make money off of these lies. I'm only a teenager with no means to pursue legal action. This means that, unfortunately, I can't do anything that will actually get results. I'd like my software to only be downloaded off my personal website. I have links to four legitimate locations to download my software and that's it. Essentially, is there anything I can do about this? As I said above, I can't pursue legal action, but is there some way I can discourage traffic to that website by blacklisting it or something? Can I make a claim on MY website to only download my software from the links I provide? Or should I just pay no mind? Because, honestly, it's a bit of a ways back in Google results. Thank you ahead of time.

  • How to Avoid Your Next 12-Month Science Project

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

  • "Oracle", "Sybase", "SQL Server" vs just "SQL/JDBC" in the CV

    - by bobah
    How would you define a testable measure of the expertise that, if you're honest with yourself, lets you write in your CV words "Oracle", "Sybase", or "SQL Server" and not just "Relational Databases, SQL, JDBC" in your software developer's CV? What every XXX-developer (XXX - a vendor name) should know? The question is similar to http://stackoverflow.com/questions/2119859/questions-every-good-database-sql-developer-should-be-able-to-answer but is vendor-specific. Below is a start of the list as an example, demonstrate what kind of answers I am hoping to get. If you are expert in X then you know that Y (X - Y below): Sybase/SQL Server - they are very similar, Sybase is much more expensive Sybase/SQL Server - for Java you can use either native Sybase/JSQLDB driver or jTDS that is using TDS protocol and can connect to SQL Server as well, TDS traffic can be dumped and analyzed with hexdump command Sybase/SQL Server - for C++ you can use FreeTDS to connect to any, for Perl - same Sybase/SQL Server - a query can return multiple result sets and return codes, all need to be processes otherwise errors can happen Sybase/SQL Server - sp_help, sp_helptext Sybase/SQL Server - your tables/views/procedures are under DBName/dbo/... Sybase - for C++ on Linux you can use Sybase client API to connect (at least until recently) SQL Server - JDBC driver has a configurable transparent failover capability Oracle - for C++ Linux one can use OTLv4 that is a very powerful yet lightweight wrapper around Oracle client API Oracle compilation (contributors: ammoQ) PLSQL Java Stored Procedures '' is null Hierarchical Query Analytic Functions Oracle Text

  • SQL SERVER – Migration Assistant Upgraded to Support SQL Server 2014

    - by Pinal Dave
    We all start somewhere when it is about database. There are different reasons, why we go for one database over another database. Usually the reason is cost and convenience. After a period of time when business is successful and traffic is growing, the same two reasons of cost and convenience start to become secondary goals. I have seen quite a lot of companies starting with free databases and after a while switching to another database as they want stability and service from the product company. Microsoft has an excellent product which lets you migrate your database from the alternate database to SQL Server. It is called SQL Server Migration Assistant (SSMA) and earlier this week, it has been upgraded to support SQL Server 2014. Now you can migrate from your database to to all editions of SQL Server 2005, SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 and SQL Server 2014. SQL Server Migration Assistant (SSMA) is a free supported tool from Microsoft. Here is where you can download SSMA v5.3 for various databases. Microsoft SQL Server Migration Assistant v5.3 for Access Microsoft SQL Server Migration Assistant (SSMA) for Access is a tool to automate migration from Microsoft Access database(s) to SQL Server Microsoft SQL Server Migration Assistant v5.3 for Oracle Microsoft SQL Server Migration Assistant (SSMA) for Oracle is a tool to automate migration from Oracle database to SQL Server. Microsoft SQL Server Migration Assistant v5.3 for Sybase Microsoft SQL Server Migration Assistant (SSMA) for Sybase is a tool to automate migration from Sybase ASE database to SQL Server.

  • Google Analytics www 301 causing issues with In-Page Analytics

    - by conrad10781
    The closest question I could find to my problem is This one. The similarity is: I have a profile in Google Analytics (GA) that has been collecting data for a year. The domain setting in GA is "http://example.com". The site, however, will redirect any non-www request, to www.example.com, via a typical .htaccess refinement. We do this to keep the traffic on the load balancers. I don't know the method the original user had in place, but we're doing a 301 on any non-www to the www equivalent. I believe this has to be somewhat standard. Where I differ from this question is in the error message I receive when trying to load the In-Page Analytics. I'm instead receiving: Error: The Website in your settings (http://example.com), redirects into a different domain. (http://www.example.com). In-Page Analytics currently works on only one domain. Note that www.example.com and example.com are NOT considered to be on the same domain. Also, make sure you're not redirecting from http:// to https:// or vice versa. I understand what's being explained, it just seems as though this can't be the end-all. I tried updating the Analytics settings, which from day one has been set as "One domain with multiple subdomains", but I don't see any options to change the URL ( which is currently set to http://example.com and not http://www.example.com ). I'd prefer not to have to change the URL if that was at all possible, but I can't seem to find any documentation or anything that provide any possible solutions.

  • Event-based server-gameloop in a server based game

    - by Chris
    I know that this site is full of questions about fixed gameloops and variable gameloops and different types of threading. But I coult find barely nothing that is related to server loops. The server has no screen to draw on. It could just run as fast as possible, but of course this makes no sense. But should it really use single "ticks" and send the updates periodically after each tick and wait for the next "tick" to update its state. Is it applicable to replace the gameloop by multilpe events? Suchs as incoming network traffic or timers? I often heared that a gameloop should be determistic, but does it really matter? For instance, when you play a shooter game against humand players and/or AI you proably would never be ably to repeat the same input twice. Is it a good idea to lose determistic behavior if it is nearly impossible to reprodruce the same input twice? So this question is more or less about whether an strictly event-based gameloop is adviseable or not and what are the pros and cons. I could imagene that an event-based gameloop could perform much faster and smoother, since you don't have bug CPU-spikes during the beginning of a new "tick". The fact that I could not find much about an event-based gameloop for servers leads me to the conclusion that inefficient or too complicated to get a real benefit from it. I'm sure if this is enough to get an idea from what I'm interessted to know, but I hope so.

  • Friday Tips #33

    - by Chris Kawalek
    Happy Friday, everyone! Our tip this week is from an excellent white paper written by our own Greg King titled Oracle VM 3: Building a Demo Environment using Oracle VM VirtualBox. In it, Greg gives you everything you need to know to set up Oracle VM Server inside of Oracle VM VirtualBox for testing and demoing. The section we're highlighting below is on how to configure the network interfaces of your virtual machines: VirtualBox comes with a few different types of network interfaces that can be used to allow communication between the VM guests and the host operating system, including network interfaces that will allow the VM guests to communicate with local and wide area networks accessed from your laptop or personal computer. However, for the purpose of the demonstration environment we will limit the network communication to include access just between your desktop and the virtual machines being managed by VirtualBox. The install process for Oracle VM VirtualBox creates a single host-only network device on your laptop or personal computer. Using the host-only network device will allow you to open a browser on your desktop to access the Oracle VM Manager running within the VirtualBox VM guest. The device will only allow network traffic between the VM guests and your host operating system, but nothing outside the confines of your laptop or personal computer. We will need to add a second host-only network since the Oracle VM Server appliance has both eth0 and eth1 configured. You can choose to use eth1 on the Oracle VM Servers or not use them – the choice is yours. But, at least the host side network device will exist if you decide to use it. Greg goes on to describe in detail how to setup the network interfaces, so you can head on over to the paper and get even more info. See you next week! -Chris

  • What are the options for hosting a small Plone site?

    - by Tina Russell
    I’ve developed a portfolio website for myself using Plone 4, and I’m looking for someplace to host it. Most Plone hosting services seem to focus on large, corporate deployments, but I need something that I can afford on a very limited budget and fits a small, single-admin website. My understanding is that my basic options are thus: I can go with a hosting service that specifically provides Plone. I know of WebFaction, but what others exist? Also, I’d have two stipulations for a Plone hosting service: (a) It needs to use Plone 4, for which I’ve developed my site, and (b) it needs to allow me SSH access to a home directory (including the Plone configuration), so that I may use my custom development eggs and such. I could use a VPS hosting service. What are my options here? Again, I need something cheap and scaled to my level. I could use Amazon EC2 or a similar service (please tell me of any) and pay by the tiniest unit of data. I’m a little scared of this because I have no idea how to do a cost-benefit analysis between this and a regular VPS host. The advantage of this approach would be that I only pay for what I use, making it very scalable, but I don’t know how the overall cost would compare to any VPS host under similar circumstances. What factors enter into the cost of Amazon EC2? What can I expect to pay under either option for regular traffic for a new website? Which one is more desirable for when a rush of visitors drive up my bandwidth bill? One last note: I know Plone isn’t common for websites for individuals, but please don’t try to talk me out of it here; that’s a completely different subject. For now, assume I’m sticking with Plone for good. Also, I have seen the Plone hosting services list on Plone.org—it’s twenty pages long, and the first page was nothing but professional Plone consulting services that sometimes offer hosting for business clients. So, that wasn’t much help. Thank you!

  • Set up a GUI managed stateful filtering firewall?

    - by Azendale
    What ways are there of setting up a stateful filtering* firewall whose rules can be managed by a GUI? Can GUFW do it? FireStarter? (or should that be avoided because it is supposedly no longer updated?) *By filtering, I'm mean the traffic I am setting rules up for is not destined for this computer. It is either from or to other computers on my LAN. Say, for (a simplified, hypothetical) example: I have an ethernet connection at my dorm that I have plugged into eth0. It gets an address of 192.168.1.185 and I also have 192.168.185.0/24 routed to me, so I don't have to do any NAT. I have a hub attached to my second ethernet port (eth1) with a few Windows computers and I give addresses out of my 192.168.185.0/24 block with DHCP. How can I use my Ubuntu box to block incoming connections from eth0 that are being routed to my Windows computers and let through just a few specific ports (so fellow students can't see what files my Windows boxes are sharing via SMB)?

    Lately we've published a lot of content about virtualization. Here's a sampling. Podcat: Technology Preview of Transcendent Memory Turns out that in a virtual environment, RAM is the bottleneck. Not because it's slow, it's not, but because each CPU still had to use its own RAM. Which gets expensive. In this podcast, Dan Magenheimer describes how Oracle and the open source community taught the guest kernel in Oracle Linux to share its memory with other CPU's. Transcendent memory will wind up saving large data centers a lot of money. Find out how.

  • How to fix some damages from site hack?

    - by Towhid
    My site had been hacked. I found vulnerability,fixed it, and removed shell scripts. But hacker had uploaded thousands of web pages on my web server. after I removed those pages I got over 4 thousand "Not Found" Pages on my site(All linked from an external free domain and host which is removed now). Also hundreds of Keywords had been added to my site. after 3 weeks I can still see keywords from removed pages on my Google Webmaster Tools. I had 1st result on google search for certain keywords but now I am on 3rd page for the same keywords. 50% of my traffic was from google which is now reduced to 6%. How can I fix both those "Not Found" pages problem and new useless keywords? and Will it be enough to get me back on first result on google? P.S: 1)Both vulnerability and uploaded files are certainly removed. 2)My site is not infected, checked on google webmaster and a few other security web scan tools. 3) all files had been uploaded on one directory so i got something like site.com/hacked/page1.html and site.com/hacked/webpage2.html

  • Apache VERY high page load time

    - by Aaron Waller
    My Drupal 6 site has been running smoothly for years but recently has experienced intermittent periods of extreme slowness (10-60 sec page loads). Several hours of slowness followed by hours of normal (4-6 sec) page loads. The page always loads with no error, just sometimes takes forever. My setup: Windows Server 2003 Apache/2.2.15 (Win32) Jrun/4.0 PHP 5 MySql 5.1 Drupal 6 Cold fusion 9 Vmware virtual environment DMZ behind a corporate firewall Traffic: 1-3 hits/sec avg Troubleshooting No applicable errors in apache error log No errors in drupal event log Drupal devel module shows 242 queries in 366.23 milliseconds,page execution time 2069.62 ms. (So it looks like queries and php scripts are not the problem) NO unusually high CPU, memory, or disk IO Cold fusion apps, and other static pages outside of drupal also load slow webpagetest.org test shows very high time-to-first-byte The problem seems to be with Apache responding to requests, but previously I've only seen this behavior under 100% cpu load. Judging solely by resource monitoring, it looks as though very little is going on. Here is the kicker - roughly half of the site's access comes from our LAN, but if I disable the firewall rule and block access from outside of our network, internal (LAN) access (1000+ devices) is speedy. But as soon as outside access is restored the site is crippled. Apache config? Crawlers/bots? Attackers? I'm at the end of my rope, where should I be looking to determine where the problem lies?
