• JavaOne Latin America 2012 Trip Report

  - by reza_rahman

  JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

• Standards Corner: Preventing Pervasive Monitoring

  - by independentid

   Phil Hunt is an active member of multiple industry standards groups and committees and has spearheaded discussions, creation and ratifications of industry standards including the Kantara Identity Governance Framework, among others. Being an active voice in the industry standards development world, we have invited him to share his discussions, thoughts, news & updates, and discuss use cases, implementation success stories (and even failures) around industry standards on this monthly column. Author: Phil Hunt On Wednesday night, I watched NBC’s interview of Edward Snowden. The past year has been tumultuous one in the IT security industry. There has been some amazing revelations about the activities of governments around the world; and, we have had several instances of major security bugs in key security libraries: Apple's ‘gotofail’ bug  the OpenSSL Heartbleed bug, not to mention Java’s zero day bug, and others. Snowden’s information showed the IT industry has been underestimating the need for security, and highlighted a general trend of lax use of TLS and poorly implemented security on the Internet. This did not go unnoticed in the standards community and in particular the IETF. Last November, the IETF (Internet Engineering Task Force) met in Vancouver Canada, where the issue of “Internet Hardening” was discussed in a plenary session. Presentations were given by Bruce Schneier, Brian Carpenter,  and Stephen Farrell describing the problem, the work done so far, and potential IETF activities to address the problem pervasive monitoring. At the end of the presentation, the IETF called for consensus on the issue. If you know engineers, you know that it takes a while for a large group to arrive at a consensus and this group numbered approximately 3000. When asked if the IETF should respond to pervasive surveillance attacks? There was an overwhelming response for ‘Yes'. When it came to 'No', the room echoed in silence. This was just the first of several consensus questions that were each overwhelmingly in favour of response. This is the equivalent of a unanimous opinion for the IETF. Since the meeting, the IETF has followed through with the recent publication of a new “best practices” document on Pervasive Monitoring (RFC 7258). This document is extremely sensitive in its approach and separates the politics of monitoring from the technical ones. Pervasive Monitoring (PM) is widespread (and often covert) surveillance through intrusive gathering of protocol artefacts, including application content, or protocol metadata such as headers. Active or passive wiretaps and traffic analysis, (e.g., correlation, timing or measuring packet sizes), or subverting the cryptographic keys used to secure protocols can also be used as part of pervasive monitoring. PM is distinguished by being indiscriminate and very large scale, rather than by introducing new types of technical compromise. The IETF community's technical assessment is that PM is an attack on the privacy of Internet users and organisations. The IETF community has expressed strong agreement that PM is an attack that needs to be mitigated where possible, via the design of protocols that make PM significantly more expensive or infeasible. Pervasive monitoring was discussed at the technical plenary of the November 2013 IETF meeting [IETF88Plenary] and then through extensive exchanges on IETF mailing lists. This document records the IETF community's consensus and establishes the technical nature of PM. The draft goes on to further qualify what it means by “attack”, clarifying that  The term is used here to refer to behavior that subverts the intent of communicating parties without the agreement of those parties. An attack may change the content of the communication, record the content or external characteristics of the communication, or through correlation with other communication events, reveal information the parties did not intend to be revealed. It may also have other effects that similarly subvert the intent of a communicator.  The past year has shown that Internet specification authors need to put more emphasis into information security and integrity. The year also showed that specifications are not good enough. The implementations of security and protocol specifications have to be of high quality and superior testing. I’m proud to say Oracle has been a strong proponent of this, having already established its own secure coding practices.

• Tuning Default WorkManager - Advantages and Disadvantages

  - by Murali Veligeti

  Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

• Analytics in an Omni-Channel World

  - by David Dorf

  Retail has been around ever since mankind started bartering.  The earliest transactions were very specific to the individuals buying and selling, then someone had the bright idea to open a store.  Those transactions were a little more generic, but the store owner still knew his customers and what they wanted.  As the chains rolled out, customer intimacy was sacrificed for scale, and retailers began to rely on segments and clusters.  But thanks to the widespread availability of data and the technology to convert said data into information, retailers are getting back to details. The retail industry is following a maturity model for analytics that is has progressed through five stages, each delivering more value than the previous. Store Analytics Brick-and-mortar retailers (and pure-play catalogers as well) that collect anonymous basket-level data are able to get some sense of demand to help with allocation decisions.  Promotions and foot-traffic can be measured to understand marketing effectiveness and perhaps focus groups can help test ideas.  But decisions are influenced by the majority, using faceless customer segments and aggregated industry data points.  Loyalty programs help a little, but in many cases the cost outweighs the benefits. Web Analytics The Web made it much easier to collect data on specific, yet still anonymous consumers using cookies to track visits. Clickstreams and product searches are analyzed to understand the purchase journey, gauge demand, and better understand up-selling opportunities.  Personalization begins to allow retailers target market consumers with recommendations. Cross-Channel Analytics This phase is a minor one, but where most retailers probably sit today.  They are able to use information from one channel to bolster activities in another. However, there are technical challenges combining data silos so its not an easy task.  But for those retailers that are able to perform analytics on both sources of data, the pay-off is pretty nice.  Revenue per customer begins to go up as customers have a better brand experience. Mobile & Social Analytics Big data technologies are enabling a 360-degree view of the customer by incorporating psychographic data from social sites alongside traditional demographic data.  Retailers can track individual preferences, opinions, hobbies, etc. in order to understand a consumer's motivations.  Using mobile devices, consumers can interact with brands anywhere, anytime, accessing deep product information and reviews.  Mobile, combined with a loyalty program, presents an opportunity to put shopping into geographic context, understanding paths to the store, patterns within the store, and be an always-on advertising conduit. Omni-Channel Analytics All this data along with the proper technology represents a new paradigm in which the clock is turned back and retail becomes very personal once again.  Rich, individualized data better illuminates demand, allows for highly localized assortments, and helps tailor up-selling.  Interactions with all channels help build an accurate profile of each consumer, and allows retailers to tailor the retail experience to meet the heightened expectations of today's sophisticated shopper.  And of course this culminates in greater customer satisfaction and business profitability.

• Tweeting about Oracle Applications Usability: Points to Consider

  - by ultan o'broin

  Here are a few pointers to anyone interested in tweeting about Oracle Applications usability or user experience (UX). These are based on my own experiences and practice, and may not necessarily reflect the views of Oracle, of course (touché, see the footer). If you are an Oracle employee and tweet about our offerings, then read up and follow the corporate social media policy. For the record, I tweet under the following account names: @ultan, @localization, @gamifyOracle, and @usableapps. The last two are supposedly Oracle subject-dedicated, but I mix it up on occassion. Fill out your Twitter account profile, and add a profile picture too. Disclose your interest. Don’t leave either the profile or image blank if you want to be taken seriously (or followed by me). Don’t tweet from a locked down Twitter account, as the message cannot be circulated to anyone who doesn't follow you. Open up the account if you really want to get that UX message out. Stay on message. The usable apps website, Misha Vaughan's VoX blog, and the Oracle Applications blog are good sources of UX messages and information, but you can find many other product team, individual, and corporate-wide sources with a little bit of searching. Set up a Google Alert with pertinent related keywords to get a daily digest of new information right in your inbox. Be original about it. Add your own insight and wit to the message, were relevant. Just circulating and RTing stock headlines adds no value to your effort or to the reader, and is somewhat lazy, in my opinion. Leave room for RTing of your tweet. So, don’t max out those 140 characters. Keep it under 130 if you want to be RTed without modification (or at all-I am not a fan of modifying tweets [MT], way too much effort for the medium). Remove articles and punctuation marks and use fragments, abbreviations, and so on at will to keep the tweet short enough, but leave keywords intact, as people search on those. Follow any Fusion UX Advocates who are on Twitter too (you can search for these names), and not just Oracle employees. Don't just follow people you like or think like you, or those who you think like you or are like-minded. Take a look at who is following or being followed by other tweeters and er, follow up. Create and socialize others to use an easily remembered or typed hashtag, or use what’s already popularized (for an event or conference, for example). We used #gamifyOracle for the applications UX gamification design jam, and other popular applications UX ones are #fusionapps and #usableapps (or at least I’m trying to popularize it). But, before you start the messaging, if you want to keep a record of the hashtag traffic, then set it up with an archiving service. Twitter’s own tweet lifespan is short. Don't mix up hashtags (#) with Twitter handles (@) that have the same name. Sending a tweet to @gamifyOracle will just be seen by @gamifyOracle (me) and any followers we have in common. Sending it to #gamifyOracle is seen by anyone following or searching for that hashtag. No dissing the competition. But there is no rule about not following them on Twitter to see the market reactions to Oracle announcements and this can even let you can tailor your own message accordingly. Don’t be boring. Mix it up a bit. Every 10th or so tweet, divert into other areas of interest, personal ones, even. No constant “I just received K+ in this and that” or “I just checked into wherever” on foursquare pouring into the Twittersteam, please. I just don’t care and will probably unfollow such people pretty quickly. And now, your Twitter tips and experiences with this subject? Them go in the comments...

• Hyper-V Live Migration across Sites!

  - by Ryan Roussel

  One of the great sessions I sat in on at Tech Ed this week was stretching a Windows 2008 R2 Hyper-V  Failover Cluster across sites.  With this ability, you could actually implement a Hyper-V cluster where you could migrate or even Live Migrate VMs across sites.   With this area’s propensity for Hurricanes, this will be a very popular topic for me over the next few months. While this technology is possible today, it’s also very complicated and can be very expensive to implement.    First your WAN connection has to support the ability to trunk your VLAN across both sites in order to Live Migrate.  This means you can’t use a Layer 3 routed connection like MPLS.  It has to be a Metro Ethernet connection or "Dark Fiber”.  Dark Fiber is unused Fiber already in the ground that can be leased from  various providers. Both of these connections would allow you to trunk layer 2 across your WAN.  Cisco does have the ability to trunk layer 2 across a routed connection by muxing the traffic but this is only available in their Nexus product line which has a very steep price tag.   If you are stuck with MPLS or the like and Nexus switching is not a realistic possibility, you will have to implement a multi-subnet cluster in which case Live Migration won’t be possible.  However you can still failover VMs to the remote site with some planning and manual intervention.  The consideration here is that the VMs will be on a different subnet once migrated, so you will have to change the IP addressing of your VMs.  This also has ramifications with DNS and Name resolution to control your down time.  DHCP with Reservations for your VMs is the preferred method to achieve the IP changes as this will automate that part of the process.   Secondly, you will have to have  a mechanism to replicate your storage across both sites.  Many SAN vendors natively support hardware based synchronous and asynchronous replication.  Some even support cluster shared volumes which were introduced in 2008 R2.   If your SANs do not support this natively, there are alternative file based replication products either software based like Double Take or hardware appliance like EMC.  Be sure to check with your vendor on the support of Disk majority if you’re replicating your quorum disk between SANs.   The last consideration is the ability to maintain quorum for your cluster.  If your replication provider does not support Disk Majority through replication, you will have to explore Node Majority with File Share Witness.  This will affect your design as a 3 node cluster with 1 node at the remote site and FSW at the production site would not have the ability to maintain quorum if the production site was lost. MS best practice for this would be to implement an even node cluster with 2 nodes at  each site and the FSW at a third site.   And there you have it.  While some considerations and research goes into implementing this solution, even a multi-subnet solution would be invaluable to organizations in the implementations of “warm” DR sites.

• JavaOne User Group Sunday

  - by Tori Wieldt

  Before any "official" sessions of JavaOne 2012, the Java community was already sizzling. User Group Sunday was a great success, with several sessions offered by Java community members for anyone wanting to attend. Sessions were both about Java and best practices for running a JUG. Technical sessions included "Autoscaling Web Java Applications: Handle Peak Traffic with Zero Downtime and Minimized Cost,"  "Using Java with HTML5 and CSS3," and "Gooey and Sticky Bits: Everything You Ever Wanted to Know About Java." Several sessions were about how to start and run a JUG, like "Getting Speakers, Finding Sponsors, Planning Events: A Day in the Life of a JUG" and "JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group." Badr ElHouari and Faiçal Boutaounte presented the session "Why Communities Are Important and How to Start One." They used the example of the Morocco JUG, which they started. Before the JUG, there was no "Java community," they explained. They shared their best practices, including: have fun, enjoy what you are doing get a free venue to have regular meetings, a University is a good choice run a conference, it gives you visibility and brings in new members students are a great way to grow a JUG Badr was proud to mention JMaghreb, a first-time conference that the Morocco JUG is hosting in November. They have secured sponsors and international speakers, and are able to offer a free conference for Java developers in North Africa. The session also included a free-flowing discussion about recruiters (OK to come to meetings, but not to dominate them), giving out email addresses (NEVER do without permission), no-show rates (50% for free events) and the importance of good content (good speakers really help!). Trisha Gee, member of the London Java Community (LJC) was one of the presenters for the session "Benefits of Open Source." She explained how open sourcing the LMAX Disruptor (a high performance inter-thread messaging library) gave her company LMAX several benefits, including more users, more really good quality new hires, and more access to 3rd party companies. Being open source raised the visibility of the company and the product, which was good in many ways. "We hired six really good coders in three months," Gee said. They also got community contributors for their code and more cred with technologists. "We had been unsuccessful at getting access to executives from other companies in the high-performance space. But once we were open source, the techies at the company had heard of us, knew our code was good, and that opened lots of doors for us." So, instead of "giving away the secret sauce," by going open source, LMAX gained many benefits. "It was a great day," said Bruno Souza, AKA The Brazilian Java Man, "the sessions were well attended and there was lots of good interaction." Sizzle and steak!

• Unable to Sign in to the Microsoft Online Services Signin application from Windows 7 client located behind ISA firewall

  - by Ravindra Pamidi

  A while ago i helped a customer troubleshoot authentication problem with Microsoft Online Services Signin application.  This customer was evaluating Microsoft BPOS (Business Productivity Online Services) and was having trouble using the single sign on application behind ISA 2004 firewall.The network structure is fairly simple with single Windows 2003 Active Directory domain and Windows 7 clients. On a successful logon to the Microsoft Online Services Signin application, this application provides single signon functionality to all of Microsoft online services in the BPOS package. Symptoms:When trying to signin it fails with error "The service is currently unavailable. Please try again later. If problems continue, contact your service administrator". If ISA 2004 firewall is removed from the picture the authentication succeeds.Troubleshooting: Enabled ISA Server firewall logging along with Microsoft Network Monitor tool on the Windows 7 Client while reproducing the issue. Analysis of the ISA Server Firewall logs and Microsoft Network capture revealed that the Microsoft Online Services Sign In application when sending request to ISA Server does not send the domain credentials and as a result ISA Server responds with an error code of HTTP 407 Proxy authentication required listing out the supported authentication mechanisms.  The application in question is expected to send the credentials of the domain user in response to this request. However in this case, it fails to send the logged on user's domain credentials. Bit of researching on the Internet revealed that The "Microsoft Online Services Sign In" application by default does not support Outbound Internet Proxy authentication. In order for it to send the logged on user's domain credentials we had to make  changes to its configuration file "SignIn.exe.config" located under "Program Files\Microsoft Online Services\Sign In" folder. Step by Step details to configure the configuration file are documented on Microsoft TechNet website given below.  Configure your outbound authenticating proxy serverhttp://www.microsoft.com/online/help/en-us/helphowto/cc54100d-d149-45a9-8e96-f248ecb1b596.htm After the above problem was addressed we were still not able to use the "Microsoft Online Services Sign In" application and it failed with the same error.  Analysis of another network capture revealed that the application in question is now sending the required credentials and the connection seems to terminate at a later stage. Enabled verbose logging for the "Microsoft Online Services Sign In" application and then reproduced the problem. Analysis of the logs revealed a time difference between the local client and Microsoft Online services server of around seven minutes which is above the acceptable time skew of five minutes. Excerpt from Microsoft Online Services Sign In application verbose log:  1/26/2012 1:57:51 PM Verbose SingleSignOn.GetSSOGenericInterface SSO Interface URL: https://signinservice.apac.microsoftonline.com/ssoservice/UID1/26/2012 1:57:52 PM Exception SSOSignIn.SignIn The security timestamp is invalid because its creation time ('2012-01-26T08:34:52.767Z') is in the future. Current time is '2012-01-26T08:27:52.987Z' and allowed clock skew is '00:05:00'.1/26/2012 1:57:52 PM Exception SSOSignIn.SignIn  Although the Windows 7 Clients successfully synchronized time to the domain controller for the domain, the domain controller was not configured to synchronize time with external NTP servers. This caused a gradual drift in time on the network thus resulting in the above issue. Reconfigured the domain controller holding the PDC FSMO role to synchronize time with external time source ( time.nist.gov ) and edited the system policy on the ISA server firewall to allow NTP traffic to time.nist.gov Configure the time source for the forest:Windows Time Servicehttp://technet.microsoft.com/en-us/library/cc794937(WS.10).aspx Forced synchronization of Windows time using the command w32tm /resync on the domain controller and later on the clients each of which had corrected the seven minutes difference. This resolved the problem with logon to Microsoft Online Services Sign In.

• PASS Summit 2013 Review

  - by Ajarn Mark Caldwell

  As a long-standing member of PASS who lives in the greater Seattle area and has attended about nine of these Summits, let me start out by saying how GREAT it was to go to Charlotte, North Carolina this year.  Many of the new folks that I met at the Summit this year, upon hearing that I was from Seattle, commented that I must have been disappointed to have to travel to the Summit this year after 5 years in a row in Seattle.  Well, nothing could be further from the truth.  I cheered loudly when I first heard that the 2013 Summit would be outside Seattle.  I have many fond memories of trips to Orlando, Florida and Grapevine, Texas for past Summits (missed out on Denver, unfortunately).  And there is a funny dynamic that takes place when the conference is local.  If you do as I have done the last several years and saved my company money by not getting a hotel, but rather just commuting from home, then both family and coworkers tend to act like you’re just on a normal schedule.  For example, I have a young family, and my wife and kids really wanted to still see me come home “after work”, but there are a whole lot of after-hours activities, social events, and great food to be enjoyed at the Summit each year.  Even more so if you really capitalize on the opportunities to meet face-to-face with people you either met at previous summits or have spoken to or heard of, from Twitter, blogs, and forums.  Then there is also the lovely commuting in Seattle traffic from neighboring cities rather than the convenience of just walking across the street from your hotel.  So I’m just saying, there are really nice aspects of having the conference 2500 miles away. Beyond that, the training was fantastic as usual.  The SQL Server community has many outstanding presenters and experts with deep knowledge of the tools who are extremely willing to share all of that with anyone who wants to listen.  The opening video with PASS President Bill Graziano in a NASCAR race turned dream sequence was very well done, and the keynotes, as usual, were great.  This year I was particularly impressed with how well attended were the Professional Development sessions.  Not too many years ago, those were very sparsely attended, but this year, the two that I attended were standing-room only, and these were not tiny rooms.  I would say this is a testament to both the maturity of the attendees realizing how important these topics are to career success, as well as to the ever-increasing skills of the presenters and the program committee for selecting speakers and topics that resonated with people.  If, as is usually the case, you were not able to get to every session that you wanted to because there were just too darn many good ones, I encourage you to get the recordings. Overall, it was a great time as these events always are.  It was wonderful to see old friends and make new ones, and the people of Charlotte did an awesome job hosting the event and letting their hospitality shine (extra kudos to SQLSentry for all they did with the shuttle, maps, and other event sponsorships).  We’re back in Seattle next year (it is a release year, after all) but I would say that with the success of this year’s event, I strongly encourage the Board and PASS HQ to firmly reestablish the location rotation schedule.  I’ll even go so far as to suggest standardizing on an alternating Seattle – Charlotte schedule, or something like that. If you missed the Summit this year, start saving now, and register early, so you can join us!

• Enabling Google Webmaster Tools With Your GWB Blog

  - by ToStringTheory

  I’ll be honest and save you some time, if you don’t have your own domain for your GWB blog, this won’t help, you may just want to move on…  I don’t want to waste your time……… Still here?  Good.  How great are Google’s website tools?  I don’t just mean Analytics which rocks, but also their Webmaster Tools (https://www.google.com/webmasters/tools/) which gives you a glimpse into the queries that provide you your website traffic, search engine behavior on your site, and important keywords, just to name a few.   Pictured Above: Cool statistics. Problem Thanks to svickn over at wtfnext.com (another GeeksWithBlogs blog), we already have the knowledge on how to setup Google Analytics (wtfnext.com - How to: Set up Google Analytics on your GeeksWithBlogs blog).  However, one of the questions raised in the post, and even semi-answered in the questions, was how to setup Google Webmaster Tools with your blog as well. At first glance, it seems like it can’t be done.  Google graciously gives you several different options on how to authorize that you own a site.  The authentication options are: 1. (Recommended) – Upload an HTML file to your server 2. Add a meta tag to your site’s home page 3. Use your Google Analytics account 4. Add a DNS record to your domain’s configuration Since you don’t have access to the base path, you can’t do #1.  Same goes for #2 since you can’t edit the master/index page.  As for #3, they REQUIRE the Analytics code to be in the <head> section of your page, so even though we can use the workaround of hosting it in the news section, it won’t allow it since it isn’t in the correct place. Solution Last I checked, I didn’t see the DNS record option for Webmaster Tools.  Maybe this was recently added, or maybe I don’t remember it since I was always able to use some other method to authorize it.  In this case though, this is the option that we need.  My registrar wasn’t in their list, but they provide detailed enough instructions for the ‘Other’ option: Simply create a TXT record with your domain hoster (mine is DynDns), fill in the tag information, and then click verify.  My entry was able to be resolved immediately, but since you are working with DNS, it may take longer.  If after 24 hours you still aren’t able to verify, you can use a site such as mxtoolbox.com, and in the searchbox type “txt: {domain-name-here}”, to see if your TXT record was entered successfully. It is pretty simple to setup the TXT entry in DynDns, but if you have questions/comments, feel free to post them. Conclusion With this simple workaround (not really a workaround, but feature since they offer it..), you are now able to see loads of information regarding your standings in the world of the Google Search Engine.  No critical issues?  Did I do something wrong?! As an aside, you can do the same thing with the Bing Webmaster Tools by adding a CNAME record to bing.verify.com…  Instructions can be found on the ‘Add Site’ popup when adding your site. If you don’t have your own domain, but continued, to read to this point – thank you!

• How do you update live web sites with code changes?

  - by Aaron Anodide

  I know this is a very basic question. If someone could humor me and tell me how they would handle this, I'd be greatful. I decided to post this because I am about to install SynchToy to remedy the issue below, and I feel a bit unprofessional using a "Toy" but I can't think of a better way. Many times I find when I am in this situation, I am missing some painfully obvious way to do things - this comes from being the only developer in the company. ASP.NET web application developed on my computer at work Solution has 2 projects: Website (files) WebsiteLib (C#/dll) Using a Git repository Deployed on a GoGrid 2008R2 web server Deployment: Make code changes. Push to Git. Remote desktop to server. Pull from Git. Overwrite the live files by dragging/dropping with windows explorer. In Step 5 I delete all the files from the website root.. this can't be a good thing to do. That's why I am about to install SynchToy... UPDATE: THANKS for all the useful responses. I can't pick which one to mark answer - between using a web deployment - it looks like I have several useful suggesitons: Web Project = whole site packaged into a single DLL - downside for me I can't push simple updates - being a lone developer in a company of 50, this remains something that is simpler at times. Pulling straight from SCM into web root of site - i originally didn't do this out of fear that my SCM hidden directory might end up being exposed, but the answers here helped me get over that (although i still don't like having one more thing to worry about forgetting to make sure is still true over time) Using a web farm, and systematically deploying to nodes - this is the ideal solution for zero downtime, which is actually something I care about since the site is essentially a real time revenue source for my company - i might have a hard time convincing them to double the cost of the servers though. -- finally, the re-enforcement of the basic principal that there needs to be a single click deployment for the site OR ELSE THERE SOMETHING WRONG is probably the most useful thing I got out of the answers. UPDATE 2: I thought I come back to this and update with the actual solution that's been in place for many months now and is working perfectly (for my single web server solution). The process I use is: Make code changes Push to Git Remote desktop to server Pull from Git Run the following batch script: cd C:\Users\Administrator %systemroot%\system32\inetsrv\appcmd.exe stop site "/site.name:Default Web Site" robocopy Documents\code\da\1\work\Tree\LendingTreeWebSite1 c:\inetpub\wwwroot /E /XF connectionsconfig Web.config %systemroot%\system32\inetsrv\appcmd.exe start site "/site.name:Default Web Site" As you can see this brings the site down, uses robocopy to intelligently copy the files that have changed then brings the site back up. It typically runs in less than 2 seconds. Since peak traffic on this site is about 2 requests per second, missing 4 requests per site update is acceptable. Sine I've gotten more proficient with Git I've found that the first four steps above being a "manual process" is also acceptable, although I'm sure I could roll the whole thing into a single click if I wanted to. The documentation for AppCmd.exe is here. The documentation for Robocopy is here.

• When things go awry

  - by Phil Factor

  The moment the Entrepreneur opened his mouth on prime-time national TV, spelled out the URL and waxed big on how exciting ‘his’ new website was, I knew I was in for a busy night. I’d designed and built it. All at once, half a million people tried to log into the website. Although all my stress-testing paid off, I have to admit that the network locked up tight long before there was any danger of a database or website problem. Soon afterwards, the Entrepreneur and the Big Boss were there in the autopsy meeting. We picked through all our systems in detail to see how they’d borne the unexpected strain. Mercifully, in view of the sour mood of the Big Boss, it turned out that the only thing we could have done better was buy a bigger pipe to and from the internet. We’d specified that ‘big pipe’ when designing the system. The Big Boss had then railed at the cost and so we’d subsequently compromised. I felt that my design decisions were vindicated. The Big Boss brooded for a while. Then he made the significant comment: “What really ****** me off is the fact that, for ten minutes, we couldn’t take people’s money.” At that point I stopped feeling smug. Had the internet connection been better, the system would have reached its limit and failed rather precipitously, and that wasn’t what he wanted. Then it occurred to me that what had gummed up the connection was all those images on the site, that had made it so impressive for the visitors. If there had been a way to automatically pare down the site to the bare essentials under stress… Hmm. I began to consider disaster-recovery in the broadest sense – maintaining a service in spite of unusual or unexpected events. What he said makes a lot of sense: sacrifice whatever isn’t essential to keep the core service running when we approach the capacity limits. Maybe in IT we should borrow (or revive) the business concept of the ‘Skeleton service’, maintaining only the priority parts under stress, using a process that is well-prepared and carefully rehearsed. How might this work? Whatever the event we have to prepare for, it is all about understanding the priorities; knowing what one can dispense with when the going gets tough. In the event of database disaster, it’s much faster to deploy a skeletal system with only the essential data than to restore the entire system, though there would have to be a reconciliation process to update the revived database retrospectively, once the emergency was over. It isn’t just the database that could be designed for resilience. One could prepare for unusually high traffic in a website by designing a system that degraded gradually to a ‘skeletal’ site, one that maintained the commercial essentials without fat images, JavaScript libraries and razzmatazz. This is all what the Big Boss scathingly called ‘a mere technicality’. It seems to me that what is needed first is a culture of application and database design which acknowledges that we live in a very imperfect world, and react accordingly when things go awry.

• Cloud Adoption Challenges

  - by Herve Roggero

  Originally posted on: http://geekswithblogs.net/hroggero/archive/2013/11/07/cloud-adoption-challenges.aspxWhile cloud computing makes sense for most organizations and countless projects, I have seen customers significantly struggle with cloud adoption challenges. This blog post is not an attempt to provide a generic assessment of cloud adoption; rather it is an account of personal experiences in the field, some of which may or may not apply to your organization. Cloud First, Burst? In the rush to cloud adoption some companies have made the decision to redesign their core system with a cloud first approach. However a cloud first approach means that the system may not work anymore on-premises after it has been redesigned, specifically if the system depends on Platform as a Service (PaaS) components (such as Azure Tables). While PaaS makes sense when your company is in a position to adopt the cloud exclusively, it can be difficult to leverage with systems that need to work in different clouds or on-premises. As a result, some companies are starting to rethink their cloud strategy by designing for on-premises first, and modify only the necessary components to burst when needed in the cloud. This generally means that the components need to work equally well in any environment, which requires leveraging Infrastructure as a Service (IaaS) or additional investments for PaaS applications, or both.  What’s the Problem? Although most companies can benefit from cloud computing, not all of them can clearly identify a business reason for doing so other than in very generic terms. I heard many companies claim “it’s cheaper”, or “it allows us to scale”, without any specific metric or clear strategy behind the adoption decision. Other companies have a very clear strategy behind cloud adoption and can precisely articulate business benefits, such as “we have a 500% increase in traffic twice a year, so we need to burst in the cloud to avoid doubling our network and server capacity”. Understanding the problem being solved through by adopting cloud computing can significantly help organizations determine the optimum path and timeline to adoption. Performance or Scalability? I stopped counting the number of times I heard “the cloud doesn’t scale; our database runs faster on a laptop”.  While performance and scalability are related concepts, they are nonetheless different in nature. Performance is a measure of response time under a given load (meaning with a specific number of users), while scalability is the performance curve over various loads. For example one system could see great performance with 100 users, but timeout with 1,000 users, in which case the system wouldn’t scale. However another system could have average performance with 100 users, but display the exact same performance with 1,000,000 users, in which case the system would scale. Understanding that cloud computing does not usually provide high performance, but instead provides the tools necessary to build a scalable system (usually using PaaS services such as queuing and data federation), is fundamental to proper cloud adoption. Uptime? Last but not least, you may want to read the Service Level Agreement of your cloud provider in detail if you haven’t done so. If you are expecting 99.99% uptime annually you may be in for a surprise. Depending on the component being used, there may be no associated SLA at all! Other components may be restarted at any time, or services may experience failover conditions weekly ( or more) based on current overall conditions of the cloud service provider, most of which are outside of your control. As a result, for PaaS cloud environments (and to a certain extent some IaaS systems), applications need to assume failure and gracefully retry to be successful in the cloud in order to provide service continuity to end users.

• Is Visual Source Safe (The latest Version) really that bad? Why? What's the Best Alternative? Why? [closed]

  - by hanzolo

  Over the years I've constantly heard horror stories, had people say "Real Programmers Dont Use VSS", and so on. BUT, then in the workplace I've worked at two companies, one, a very well known public facing high traffic website, and another high end Financial Services "Web-Based" hosted solution catering to some very large, very well known companies, which is where I currently Reside and everything's working just fine (KNOCK KNOCK!!). I'm constantly interfacing with EXTREMELY Old technology with some of these financial institutions.. OLD LIKE YOU WOULDN'T BELIEVE.. which leads me to the conclusion that if it works "LEAVE IT", and that maybe there's some value in old technology? at least enough value to overrule a rewrite!? right?? Is there something fundamentally flawed with the underlying technology that VSS uses? I have a feeling that if i said "someone said VSS Sucks" they would beg to differ, most likely give me this look like i dont know -ish, and I'd never gain back their respect and my credibility (well, that'll be hard to blow.. lol), BUT, give me an argument that I can take to someone whose been coding for 30 years, that builds Platforms that leverage current technology (.NET 3.5 / SQL 2008 R2 ), write's their own ORM with scaffolding and is able to provide a quality platform that supports thousands of concurrent users on a multi-tenant hosted solution, and does not agree with any benefits from having Source Control Integrated, and yet uses the Infamous Visual Source Safe. I have extensive experience with TFS up to 2010, and honestly I think it's great when a team (beyond developers) can embrace it. I've worked side by side with someone whose a die hard SVN'r and from a purist standpoint, I see the beauty in it (I need a bit more, out of my SS, but it surely suffices). So, why are such smarties not running away from Visual Source Safe? surely if it was so bad, it would've have been realized by now, and I would not be sitting here with this simple old, Check In, Check Out, Version Resistant, Label Intensive system. But here I am... I would love to drop an argument that would be the end all argument, but if it's a matter of opinion and personal experience, there seems to be too much leeway for keeping VSS. UPDATE: I guess the best case is to have the VSS supporters check other people's experiences and draw from that until we (please no) experience the breaking factor ourselves. Until then, i wont be engaging in a discussion to migrate off of VSS.. UPDATE 11-2012: So i was able to convince everyone at my work place that since MS is sun downing Visual Source Safe it might be time to migrate over to TFS. I was able to convince them and have recently upgraded our team to Visual Studio 2012 and TFS 2012. The migration was fairly painless, had to run analyze.exe which found a bunch of errors (not sure they'll ever affect the project) and then manually run the VSSConverter.exe. Again, painless, except it took 16 hours to migrate 5 years worth of everything.. and now we're on TFS.. much more integrated.. much more cooler.. so all in all, VSS served it's purpose for years without hick-up. There were no horror stories and Visual Source Save as source control worked just fine. so to all the nay sayers (me included). there's nothing wrong with using VSS. i wouldnt start a new project with it, and i would definitely consider migrating to TFS. (it's really not super difficult and a new "wizard" type converter is due out any day now so migrating should be painless). But from my experience, it worked just fine and got the job done.

• Come up with a real-world problem in which only the best solution will do (a problem from Introduction to algorithms) [closed]

  - by Mike

  EDITED (I realized that the question certainly needs a context) The problem 1.1-5 in the book of Thomas Cormen et al Introduction to algorithms is: "Come up with a real-world problem in which only the best solution will do. Then come up with one in which a solution that is “approximately” the best is good enough." I'm interested in its first statement. And (from my understanding) it is asked to name a real-world problem where only the exact solution will work as opposed to a real-world problem where good-enough solution will be ok. So what is the difference between the exact and good enough solution. Consider some physics problem for example the simulation of the fulid flow in the permeable medium. To make this simulation happen some simplyfing assumptions have to be made when deriving a mathematical model. Otherwise the model becomes at least complex and unsolvable. Virtually any particle in the universe has its influence on the fluid flow. But not all particles are equal. Those that form the permeable medium are much more influental than the ones located light years away. Then when the mathematical model needs to be solved an exact solution can rarely be found unless the mathematical model is simple enough (wich probably means the model isn't close to reality). We take an approximate numerical method and after hours of coding and days of verification come up with the program or algorithm which is a solution. And if the model and an algorithm give results close to a real problem by some degree that is good enough soultion. Its worth noting the difference between exact solution algorithm and exact computation result. When considering real-world problems and real-world computation machines I believe all physical problems solutions where any calculations are taken can not be exact because universal physical constants are represented approximately in the computer. Any numbers are represented with the limited precision, at least limited by amount of memory available to computing machine. I can imagine plenty of problems where good-enough, good to some degree solution will work, like train scheduling, automated trading, satellite orbit calculation, health care expert systems. In that cases exact solutions can't be derived due to constraints on computation time, limitations in computer memory or due to the nature of problems. I googled this question and like what this guy suggests: there're kinds of mathematical problems that need exact solutions (little note here: because the question is taken from the book "Introduction to algorithms" the term "solution" means an algorithm or a program, which in this case gives exact answer on each input). But that's probably more of theoretical interest. So I would like to narrow down the question to: What are the real-world practical problems where only the best (exact) solution algorithm or program will do (but not the good-enough solution)? There are problems like breaking of cryptographic ciphers where only exact solution matters in practice and again in practice the process of deciphering without knowing a secret should take reasonable amount of time. Returning to the original question this is the problem where good-enough (fast-enough) solution will do there's no practical need in instant crack though it's desired. So the quality of "best" can be understood in any sense: exact, fastest, requiring least memory, having minimal possible network traffic etc. And still I want this question to be theoretical if possible. In a sense that there may be example of computer X that has limited resource R of amount Y where the best solution to problem P is the one that takes not more than available Y for inputs of size N*Y. But that's the problem of finding solution for P on computer X which is... well, good enough. My final thought that we live in a world where it is required from programming solutions to practical purposes to be good enough. In rare cases really very very good but still not the best ones. Isn't it? :) If it's not can you provide an example? Or can you name any such unsolved problem of practical interest?

• Unable to debug simple Java application in Eclipse. Cannot connect to VM. AGENT_ERROR_TRANSPORT_INIT(197)

  - by Heptaparaparshi

  When i try to debug a simple application in Eclipse i receive a following error: Cannot connect to VM com.sun.jdi.connect.TransportTimeoutException And console provides me with a lonely string: FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197) I have JRE 1.6, JRE 1.7 and JDK 1.7 installed. Tried all of them. I've seen tons of same topics, but not a single answer helped me to solve my issue. Here they are: 1) Disable Firewall. Doesn't help. I have latest Avast ver. 9.0 at the moment. I'm a bit suspicious about that software, because before updating my Avast i was able to debug in Eclipse. I think it may cause this error, but i do not have direct clues :). I may ping my machine, firewall doesn't block Eclipse traffic, etc. 2) Add strings to hosts file. No reaction. ::1 localhost.localdomain localhost 127.0.0.1 localhost 3) Changing Network Settings in Java Control Panel to "Direct" connection. Doubtful advice. Also read that thing: http://wiki.eclipse.org/Debug/FAQ Can anyone help me to find out what is happening? Or guide me in the right direction?

• Want custom title / image / description in facebook share link

  - by Ezop

  Hi! I am making a flash app that demonstrates potensial traffic injuries when driving at different speeds. I want the user to be able to share this information on facebook. However this demands that i can customize the text that will appear on facebook in some manner. I am making an url that is opened in a blank window (from the flash app itself). I specify the u and t parameters, putting the generated message as the t parameter. But this seems to always be overridden by the pages title. If i omit the title tag from the html code, the file name is used (also overriding the specified title). http://www.facebook.com/sharer.php?u=http://espentokerud.com/face/addiste.html&t=test; I also tried url-encoding the url, but to no avail. http://www.facebook.com/sharer.php?u=http%3a%2f%2fespentokerud.com%2fface%2faddiste.html&t=test; I also tried using the addthis API, but experience the same shortcomings. The funny thing is that if i post a swf, the title and description can be customized, and it is also possible to specify a screenshot. But if i dont post a swf, this seems to be ignored. I am aware that I can use meta tags on the html page to specify the thumbnail image, title and description, but some of this content has to be based on calculations inside the flash app. Can anyone help me out or point me in the right direction? I am thankful for any help!

• Jquery.get() not returning any data

  - by David Waters

  Hi I am trying to scrape other people web pages (for the forces of good not evil). I am currently trying to do this with javascript/jquery from with in a browser. I am finding that the no data is returned from the jquery.get() success call back function. My code. $.get('http://www.google.co.uk/', function (data, textStatus, XMLHttpRequest){ alert("status " + textStatus); alert('data:' + data); window.data=data; window.textStatus=textStatus; window.httpReq = XMLHttpRequest}); In my mind this should simply do a get on google store the data in window.data and we are all good. What happens is we get textStatus == success and data == "". the status on the XMLHttpRequest is 4(success). I have looked at the network traffic using a transparent proxy (Charles) and everything looks find there http status 200 plenty of data being returned. I am running this just from the Firebug console in Firefox. Any ideas?

• Windows services with windows forms in the same process

  - by andrecarlucci

  Hello, I have a c# application that runs as a windows service controlling socket connections and other things. Also, there is another windows forms application to control and configure this service (systray with start, stop, show form with configuration parameters). I'm using .net remoting to do the IPC and that was fine, but now I want to show some real traffic and other reports and remoting will not meet my performance requirements. So I want to combine both applications in one. Here is the problem: When I started the form from the windows service, nothing happened. Googling around I've found that I have to right click the service, go to Log on and check the "Allow service to interact with desktop" option. Since I don't want to ask my users to do that, I got some code googling again to set this option in the user's regedit during installation time. The problem is that even setting this option, it doesn't work. I have to open the Log On options of the service (it is checked), uncheck and check again. So, how to solve that? How is the best way to have a windows service with a systray control in the same process, available to any user logging in? UPDATE: Thanks for the comments so far, guys. I agree it is better to use IPC and I know that it is bad to mix windows services and user interfaces. Even though, I want to know how to do that.

• We have multiple app servers running against a single database. How do I ensure that each row in a q

  - by Dave

  We have about 7 app servers running .NET windows services that ping a single sql server 2005 queue table and fetch a fixed amount of records to process at fixed intervals. The amount of records to process and the amount of time between fetches are both configurable and are initially set to 100 and 30 seconds initially. Currently, my queue table has an int status column which can be either "Ready, Processing, Complete, Error". The proc that fetches the records has a sql transaction with the following code inside the transaction: 1) Fetch x number of records into temp table where the status is "Ready". The select uses a holdlock hint 2) Update the status on those records in the Queue table to "Processing" The .NET services do some processing that may take seconds or even minutes per record. Another proc is called per record that simply updates the status to "Complete". The update proc has no transaction as I'm leaning on the implicit transaction as part of the update clause here. I don't know the traffic exceptions for this but figure it will be under 10k records per day. Is this the best way to handle this scenario? If so, are there any details that I've left out, such as a hint here or there? Thanks! Dave

• Flex vs. jQuery vs. GWTvs./ Closre vs. Cappuccino vs. plain JS and HTML5?

  - by Laith J

  Hello, I'm creating my first web application and I'm really confused as to what technology to go for. My application needs to look serious (like an application), it doesn't need many colorful graphical interfaces. It only needs a toolbar, a tab bar, a split panel (preferably 3 columns), an easily-formatable text field, and a status bar. It will connect to a MySQL database through PHP (unless I go for GWT). Users will upload files. My evaluation of the options: Flex: Probably the easiest to develop but I'm pretty sure my application is something one would use on an iPad and with Flash's future on the iPad still unsure, I don't want to take the risk, otherwise Flex would've been my choice. jQuery: I've heard a lot about it and a lot of people recommend but I don't know how easy it is to use and how customizable the look of my app is. GWT: The problem with GWT is that it doesn't have many widgets. Another problem is that I'm gonna have to host the files in AppEngine's datastore and transfer them back and forth to a web server that will do operations on them (I need to process them) which adds more traffic and slows the process which worsens the user experience. Closure: It has a nice toolbar and a nice text field. I'm not sure how easy it is to use. Plus, I read an article that makes it sound really bad. Cappuccino: It has a very nice UI and it has a mac feel. I'm planning to give my application a mac feel anyway so this will save me a lot of theming. But if I go for this option I won't be able to make use of HTML5's new features (especially working offline). Plain JS and HTML5: This gives me the most flexibility but it is the hardest to work for. I'm sorry if this is subjective but I really need help with this.

• Is background tasks the solution for this problem?

  - by Trinca

  Hi. I need to develop an enterprise app that monitors the network traffic. Basically it detects if the user is in wi-fi or cellular data and save the amount of bytes was sent and received in a period of time. I saw an App at the AppStore that do exactly this job. Detecting wi-fi or cellular data is quite simple using the Reachability Sample provided by Apple. My problem is to keep monitoring the bytes sent and received while the app is in background. As it is an enterprise App, I used UIBackgroundModes "voip" to avoid the app to be terminated. I also installed the setKeepAliveTimeout method and I'm able to see the logs each 10 minutes, BUT only for 10 seconds after the method runs. I mean, setKeepAliveTimeout brings my App to run a Timer for 10 seconds each 1o minutes. I'm thinking wether or not a task in background is the best solution for my problem. I'll appreciate any comments. EDIT: Ok guys. Thats the perfect way to do it. First of all you must read this: http://www.christian-fries.de/blog/files/tag-ios.html I tried this and it works really fine. All we need to do is to create a second thread detached from the main one. This way we have a continuos threading running forever. You must see the GCD docs at Apple's website also. Second thing you should consider for an enterprise App is to set it up as a voip App, this way iOS will put your App running even after a reboot. It's a special behavior iOS has to keep voip Apps running. Thats it guys. I hope it can help you.

• How do I code Citrix web sites to use a Secure Gateway (CSG)?

  - by RAVolt

  I'm using Citrix's sample code as a base and trying to get it to generate ICA files that direct the client to use their Secure Gateway (CSG) provider. My configuration is that the ICA file's server address is replaced with a CSG ticket and traffic is forced to go to the CSG. The challenge is that both the Citrix App Server (that's providing the ICA session on 1494) and the CSG have to coordinate through a Secure Ticket Authority (STA). That means that my code needs to talk to the STA as it creates the ICA file because STA holds a ticket that the CSG needs embedded into the ICA file. Confusing? Sure! But it's much more secure. The pre-CSG code looks like this: AppLaunchInfo launchInfo = (AppLaunchInfo)userContext.launchApp(appID, new AppLaunchParams(ClientType.ICA_30)); ICAFile icaFile = userContext.convertToICAFile(launchInfo, null, null); I tried to the SSLEnabled information to the ICA generation, but it was not enough. here's that code: launchInfo.setSSLEnabled(true); launchInfo.setSSLAddress(new ServiceAddress("CSG URL", 443)); Now, it looks like I need to register the STA when I configure my farm: ConnectionRoutingPolicy policy = config.getDMZRoutingPolicy(); policy.getRules().clear(); //Set the Secure Ticketing Authorities (STAs). STAGroup STAgr = new STAGroup(); STAgr.addSTAURL(@"http://CitrixAppServerURL/scripts/ctxsta.dll"); //creat Secure Gateway conenction SGConnectionRoute SGRoute = new SGConnectionRoute(@"https://CSGURL"); SGRoute.setUseSessionReliability(false); SGRoute.setGatewayPort(80); SGRoute.setTicketAuthorities(STAgr); // add the SGRoute to the policy policy.setDefault(SGRoute); This is based on code I found on the Citrix Forums; however, it breaks my ability to connect with the Farm and get my application list! Can someone point me to an example of code that works? Or a reference document?
