• LexisNexis and Oracle Join Forces to Prevent Fraud and Identity Abuse

  - by Tanu Sood

  Author: Mark Karlstrand About the Writer:Mark Karlstrand is a Senior Product Manager at Oracle focused on innovative security for enterprise web and mobile applications. Over the last sixteen years Mark has served as director in a number of tech startups before joining Oracle in 2007. Working with a team of talented architects and engineers Mark developed Oracle Adaptive Access Manager, a best of breed access security solution.The world’s top enterprise software company and the world leader in data driven solutions have teamed up to provide a new integrated security solution to prevent fraud and misuse of identities. LexisNexis Risk Solutions, a Gold level member of Oracle PartnerNetwork (OPN), today announced it has achieved Oracle Validated Integration of its Instant Authenticate product with Oracle Identity Management.Oracle provides the most complete Identity and Access Management platform. The only identity management provider to offer advanced capabilities including device fingerprinting, location intelligence, real-time risk analysis, context-aware authentication and authorization makes the Oracle offering unique in the industry. LexisNexis Risk Solutions provides the industry leading Instant Authenticate dynamic knowledge based authentication (KBA) service which offers customers a secure and cost effective means to authenticate new user or prove authentication for password resets, lockouts and such scenarios. Oracle and LexisNexis now offer an integrated solution that combines the power of the most advanced identity management platform and superior data driven user authentication to stop identity fraud in its tracks and, in turn, offer significant operational cost savings. The solution offers the ability to challenge users with dynamic knowledge based authentication based on the risk of an access request or transaction thereby offering an additional level to other authentication methods such as static challenge questions or one-time password when needed. For example, with Oracle Identity Management self-service, the forgotten password reset workflow utilizes advanced capabilities including device fingerprinting, location intelligence, risk analysis and one-time password (OTP) via short message service (SMS) to secure this sensitive flow. Even when a user has lost or misplaced his/her mobile phone and, therefore, cannot receive the SMS, the new integrated solution eliminates the need to contact the help desk. The Oracle Identity Management platform dynamically switches to use the LexisNexis Instant Authenticate service for authentication if the user is not able to authenticate via OTP. The advanced Oracle and LexisNexis integrated solution, thus, both improves user experience and saves money by avoiding unnecessary help desk calls. Oracle Identity and Access Management secures applications, Juniper SSL VPN and other web resources with a thoroughly modern layered and context-aware platform. Users don't gain access just because they happen to have a valid username and password. An enterprise utilizing the Oracle solution has the ability to predicate access based on the specific context of the current situation. The device, location, temporal data, and any number of other attributes are evaluated in real-time to determine the specific risk at that moment. If the risk is elevated a user can be challenged for additional authentication, refused access or allowed access with limited privileges. The LexisNexis Instant Authenticate dynamic KBA service plugs into the Oracle platform to provide an additional layer of security by validating a user's identity in high risk access or transactions. The large and varied pool of data the LexisNexis solution utilizes to quiz a user makes this challenge mechanism even more robust. This strong combination of Oracle and LexisNexis user authentication capabilities greatly mitigates the risk of exposing sensitive applications and services on the Internet which helps an enterprise grow their business with confidence.Resources:Press release: LexisNexis® Achieves Oracle Validated Integration with Oracle Identity Management Oracle Access Management (HTML)Oracle Adaptive Access Manager (pdf)

• Serial plans: Threshold / Parallel_degree_limit = 1

  - by jean-pierre.dijcks

  As a very short follow up on the previous post. So here is some more on getting a serial plan and why that happens Another reason - compared to the auto DOP is not on as we looked at in the earlier post - and often more prevalent to get a serial plan is if the plan simply does not take long enough to consider a parallel path. The resulting plan and note looks like this (note that this is a serial plan!): explain plan for select count(1) from sales; SELECT PLAN_TABLE_OUTPUT FROM TABLE(DBMS_XPLAN.DISPLAY()); PLAN_TABLE_OUTPUT -------------------------------------------------------------------------------- Plan hash value: 672559287 -------------------------------------------------------------------------------------- | Id  | Operation            | Name  | Rows  | Cost (%CPU)| Time     | Pstart| Pstop | -------------------------------------------------------------------------------------- PLAN_TABLE_OUTPUT -------------------------------------------------------------------------------- |   0 | SELECT STATEMENT     |       |     1 |     5   (0)| 00:00:01 |       |     | |   1 |  SORT AGGREGATE      |       |     1 |            |          |       |     | |   2 |   PARTITION RANGE ALL|       |   960 |     5   (0)| 00:00:01 |     1 |  16 | |   3 |    TABLE ACCESS FULL | SALES |   960 |     5   (0)| 00:00:01 |     1 |  16 | Note -----    - automatic DOP: Computed Degree of Parallelism is 1 because of parallel threshold 14 rows selected. The parallel threshold is referring to parallel_min_time_threshold and since I did not change the default (10s) the plan is not being considered for a parallel degree computation and is therefore staying with the serial execution. Now we go into the land of crazy: Assume I do want this DOP=1 to happen, I could set the parameter in the init.ora, but to highlight it in this case I changed it on the session: alter session set parallel_degree_limit = 1; The result I get is: ERROR: ORA-02097: parameter cannot be modified because specified value is invalid ORA-00096: invalid value 1 for parameter parallel_degree_limit, must be from among CPU IO AUTO INTEGER>=2 Which of course makes perfect sense...

• Desktop login fails, terminal works

  - by Tobias

  I have a freshly setup 12.04 LTS pc system (120 GB SSD, 1 TB HDD, 16 GiB RAM); since a few days, I can't login to the graphical desktop anymore: there is very short flashing shell window which disappears very quickly, and I'm confronted with the login screen again. I believe there is something about modprobe and vbox, but I can't read it fast enough ... I can login to a terminal (Ctrl+Alt+F1). It did not help to chown all contents of my home directory to me:my-group, like suggested here. This is what I could find in /var/log, grepping for the date and time (I inserted linebreaks after <my-hostname>; real time values preserved): auth.log: <date> 22:43:01 <my-hostname> lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "tobias" <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session closed for user lightdm <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session opened for user tobias by (uid=0) <date> 22:43:08 <my-hostname> lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0 <date> 22:43:08 <my-hostname> lightdm: pam_unix(lightdm:session): session closed for user tobias <date> 22:43:09 <my-hostname> lightdm: pam_unix(lightdm:session): session opened for user lightdm by (uid=0) <date> 22:43:09 <my-hostname> lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0 <date> 22:43:10 <my-hostname> lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "tobias" <date> 22:43:10 <my-hostname> dbus[756]: [system] Rejected send message, 2 matched rules; type="method_call", sender="1:43" (uid=104 pid=1639 comm="/usr/lib/indicator-datetime/indicator-datetime-ser") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.15" (uid=0 pid=1005 comm="/usr/sbin/console-kit-daemon --no-daemon ") kern.log: <date> 22:43:00 <my-hostname> kernel: [ 16.084525] eth0: no IPv6 routers present syslog: <date> 22:43:00 <my-hostname> kernel: [ 16.084525] eth0: no IPv6 routers present <date> 22:43:01 <my-hostname> ntpdate[1492]: adjust time server 91.189.94.4 offset -0.162831 sec <date> 22:43:08 <my-hostname> acpid: client 969[0:0] has disconnected <date> 22:43:08 <my-hostname> acpid: client connected from 1553[0:0] <date> 22:43:08 <my-hostname> acpid: 1 client rule loaded I have Virtualbox and Truecrypt installed, but I can't think of a reason why they might prevent a graphical login. I'm confused: What is this about requirement "user ingroup nopasswdlogin" not met? I do login using a password, and the password works ok when logging in to a terminal! Can I somehow read the error output, e.g. by delaying it, redirecting it to a file, or having the system prompt me for pressing a key? Has possibly any recent update caused my problem? Should I install the pending updates? How, btw, without access to the graphical UI? I have some working knowledge about the Linux shell, but I'm new to Ubuntu. Any help would be appreciated.

• Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

  - by Chris Warner

  It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011.

• SQL – Business Intelligence: Derive Data or Information?

  - by Pinal Dave

  We all know the value of information in our lives. Whether it’s a personal decision or a business initiated one, people need it. But the question is: who is to make the distinction between data and information? We all come across a whole lot of data daily, that may be significant or not. We filter what’s required and forget about the rest. Information is filtered and distilled data. Filtering and distillation can also alter its actual meaning and natural state. Therefore, in this blog we discover some ways to ensure that we’re using business intelligence derived from the right information for making critical management decisions. Four key questions managers must ask themselves before making a decision: 1. Am I working with data or information? 2. What is it’s context? 3. How recent is it? 4. How was it derived or what is the source? The first question is probably the most important. You must know what you’re dealing with here. If you see use of adjectives and conclusions drawn, it’s information. Not raw data. You very next concern must be whether this is guised to present a particular viewpoint or perspective. It makes a lot of difference if you take a decision based on someone’s propaganda to distort real facts. Therefore, the context and the intentions of the distillation process must be clear to you. The next consideration is whether data is recent enough to hold any value. Since it has a very short shelf life, you must ensure that its context and value is not lost out of time. The last and the most important consideration is how was it derived in the first place. The observer effect is what calls the shots here. The source can change the context to a great extent if the collection methodology  and purpose is not clear. Gathering intelligence for decision making requires users to be keen observers and not take the information provided on its face value alone. These probing questions will allow you to make sure that you’re working with clean and accurate data devoid of any influence or manipulations. Only then can you be sure of deriving true business intelligence for your organization. BI technology is also a great way to ensure accuracy of reports. SQL BI Platform  provides advanced tools and techniques for all your BI needs and concerns. Koenig Solutions offers this course along with a host of other Business Intelligence and IT courses on all latest technologies available in the market today.

• Monitor SQL Server Replication Jobs

  - by Yaniv Etrogi

  The Replication infrastructure in SQL Server is implemented using SQL Server Agent to execute the various components involved in the form of a job (e.g. LogReader agent job, Distribution agent job, Merge agent job) SQL Server jobs execute a binary executable file which is basically C++ code. You can download all the scripts for this article here SQL Server Job Schedules By default each of job has only one schedule that is set to Start automatically when SQL Server Agent starts. This schedule ensures that when ever the SQL Server Agent service is started all the replication components are also put into action. This is OK and makes sense but there is one problem with this default configuration that needs improvement  -  if for any reason one of the components fails it remains down in a stopped state.   Unless you monitor the status of each component you will typically get to know about such a failure from a customer complaint as a result of missing data or data that is not up to date at the subscriber level. Furthermore, having any of these components in a stopped state can lead to more severe problems if not corrected within a short time. The action required to improve on this default settings is in fact very simple. Adding a second schedule that is set as a Daily Reoccurring schedule which runs every 1 minute does the trick. SQL Server Agent’s scheduler module knows how to handle overlapping schedules so if the job is already being executed by another schedule it will not get executed again at the same time. So, in the event of a failure the failed job remains down for at most 60 seconds. Many DBAs are not aware of this capability and so search for more complex solutions such as having an additional dedicated job running an external code in VBS or another scripting language that detects replication jobs in a stopped state and starts them but there is no need to seek such external solutions when what is needed can be accomplished by T-SQL code. SQL Server Jobs Status In addition to the 1 minute schedule we also want to ensure that key components in the replication are enabled so I can search for those components by their Category, and set their status to enabled in case they are disabled, by executing the stored procedure MonitorEnableReplicationAgents. The jobs that I typically have handled are listed below but you may want to extend this, so below is the query to return all jobs along with their category. SELECT category_id, name FROM msdb.dbo.syscategories ORDER BY category_id; Distribution Cleanup LogReader Agent Distribution Agent Snapshot Agent Jobs By default when a publication is created, a snapshot agent job also gets created with a daily schedule. I see more organizations where the snapshot agent job does not need to be executed automatically by the SQL Server Agent  scheduler than organizations who   need a new snapshot generated automatically. To assure this setting is in place I created the stored procedure MonitorSnapshotAgentsSchedules which disables snapshot agent jobs and also deletes the job schedule. It is worth mentioning that when the publication property immediate_sync is turned off then the snapshot files are not created when the Snapshot agent is executed by the job. You control this property when the publication is created with a parameter called @immediate_sync passed to sp_addpublication and for an existing publication you can use sp_changepublication. Implementation The scripts assume the existence of a database named PerfDB. Steps: Run the scripts to create the stored procedures in the PerfDB database. Create a job that executes the stored procedures every hour. -- Verify that the 1_Minute schedule exists. EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 13; /* LogReader */ -- Verify all replication agents are enabled. EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 13; /* LogReader */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 11; /* Distribution clean up */ -- Verify that Snapshot agents are disabled and have no schedule EXEC PerfDB.dbo.MonitorSnapshotAgentsSchedules; Want to read more of about replication?

• Windows Phone 8, possible tablets and what the latest update might mean

  - by Roger Hart

  Microsoft have just announced an update to Windows Phone 8. As one of the five, maybe six people who actually bought a WP8 handset I found this interesting. Then I read the blog post about it, and rushed off to write somewhat less than a thousand words about a single picture. The blog post announces an extra column of tiles on the start screen, and support for higher resolutions. If we ignore all the usual flummery about how this will make your life better, that (and the rotation lock) sounds a little like stage setting for tablets. Looking at the preview screenshot, I started to wonder. What it’s called Phablet_5F00_StartScreenProductivity_5F00_01_5F00_072A1240.jpg Pretty conclusive. If you can brand something a “phablet” and sleep at night you’re made of sterner stuff than I am, but that’s beside the point. It’s explicit in the post that Microsoft are expecting a broader range of form factors for WP8, but they stop short of quite calling out tablet size. The extra columns and resolution definitely back that up, so why stop at a 6 inch “phablet”? Sadly, the string of numbers there don’t really look like a Lumia model number – that would be a bit tendentious even for a speculative blog post about a single screenshot. “Productivity” is interesting too. I get into this a bit more below, but this is a pretty clear pitch for a business device. What it looks like Something that would look quite decent on a 7 inch screen, but something a bit too vertical to go toe-to-toe with the Surface. Certainly, it would look a lot better on a large-factor phone than any of the current models. Those tiles are going to get cramped and a bit ugly if the handsets aren’t getting bigger. What’s on it You have a bunch of missed calls, you rarely text, use a stocks app, and your budget spreadsheet and meeting notes are a thumb-reach away. Outlook is your main form of email. You care enough about LinkedIn to not only install its app but give it a huge live tile. There’s no beating about the bush here, the implicit persona is a corporate exec. With Nokia in the bag and Blackberry pushing daisies, that may not be a stupid play. There’s almost certainly a niche there if they can parlay their corporate credentials into filling it before BYOD (which functionally means an iPhone) reaches the late adopters. The really quite slick WP8 Office implementation ought to help here. This is the face they’ve chosen to present, the cultural milieu they’re normalizing for Windows Phone. It’s an iPhone for Serious Business Grown-ups. Could work, I guess. Does it mean anything? Is the latest WP8 update a sign that we can expect to see tablets running Windows Phone rather than WinRT? Well, WinRT tablets haven’t exactly taken off but I’m not quite going to make a leap like that just from a file name and a column of icons. I feel pretty safe, however, conjecturing that Microsoft would like to squeeze a WP8 “phablet” into the palm of every exec who’s ever grumbled about their Blackberry, and this release might get them a bit closer. If it works well incrementing up to larger devices, then that could be a fair hedge against WinRt crashing and burning any harder in the marketplace.

• Oracle Tutor: Installing Is Not Implementing or Why CIO's should care about End User Adoption

  - by emily.chorba(at)oracle.com

  Eighteen months ago I showed Tutor and UPK Productive Day One overview to a CIO friend of mine. He works in a manufacturing business which had been recently purchased by a global conglomerate. He had a major implementation coming up, but said that the corporate team would be coming in to handle the project. I asked about their end user training approach, but it was unclear to him at the time. We were in touch over the course of the implementation project. The major activities were data conversion, how-to workshops, General Ledger realignment, and report definition. The message was "Here's how we do it at corporate, and here's how you are going to do it." In short, it was an application software installation. The corporate team had experience and confidence and the effort through go-live was smooth. Some weeks after cutover, problems with customer orders began to surface. Orders could not be fulfilled in a timely fashion. The problem got worse, and the corporate emergency team was called in. After many days of analysis, the issue was tracked down and resolved, but by then there were weeks of backorders, and their customer base was impacted in a significant way. It took three months of constant handholding of customers by the sales force for good will to be reestablished, and this itself diminished a new product sales push. I learned of these results in a recent conversation with the CIO. I asked him what the solution to the problem was, and he replied that it was twofold. The first component was a lack of understanding by customer service reps about how a particular data item in order entry was to be filled in, resulting in discrepant order data. The second component was that product planners were using this data, along with data from other sources, to fill in a spreadsheet based on the abandoned system. This spreadsheet was the primary input for planning data. The result of these two inaccuracies was that key parts were not being ordered to effectively meet demand and the lead time for finished goods was pushed out by weeks. I reminded him about the Productive Day One approach, and it's focus on methodology and tools for end user training. A more collaborative solution workshop would have identified proper applications use in the new environment. Using UPK to document correct transaction entry would have provided effective guidelines to the CSRs for data entry. Using Oracle Tutor to document the manual tasks would have eliminated the use of an out of date spreadsheet. As we talked this over, he said, "I wish I knew when I started what I know now." Effective end user adoption is the most critical and most overlooked success factor in applications implementations. When the switch is thrown at go-live, employees need to know how to use the new systems to do their jobs. Their jobs are made up of manual steps and systems steps which must be performed in the right order for the implementing organization to operate smoothly. Use Tutor to document the manual policies and procedures, use UPK to document the systems tasks, and develop this documentation in conjunction with a solution workshop. This is the path to develop effective end user training material for a smooth implementation. Learn More For more information about Tutor, visit Oracle.com or the Tutor Blog.

• New JavaScript Editor

  - by Petr

  I did not write a blog post here for a few weeks. I think the last my post was  about releasing NetBeans 7.1 in the beginning of January. The reason is not that I would change the job:), but that I have concentrated on new JavaScript support/editor. The new JavaScript editor is written basically from scratch. The answer for the question "Why from beginning again, why do you just improve the old one?" is not easy and the decision has more aspects. One of the main reasons is that the old support was written 4 years ago and the architecture is limited. Also during the time, the APIs were changed and it was very hard to keep the editor up to date. Also there is a license issue etc. In short, it is time to rewrite the old JS editor.  We build up strong community about the PHP support in NetBeans and because many PHP developers also write JavaScript code I would like to ask you for a help. There is a continual PHP build with the new JavaScript support. You can download the result of the builds here. It's a zip file. You can unzip the file anywhere, where you want. I recommend to run the build with the new userdir, to avoid damaging your current userdir. It shouldn't happened, but just to be sure:). You can achieve this through the switch --userdir. So start the unzipped file from command line from the folder, where you unzipped it, can be done with this command on unix: bin/netbeans.sh --userdir /path/to/new/userdir and on windows: bin\netbeans.exe --userdir D:\path\to\new\userdir For the developers who use continual php build already, it's well known. There is also full IDE build with the new JavaScript support for people, who need more than only PHP support.  Because the builds with the new JavaScript editor is created from a branch, there are not nightly builds available. They will be, when we merge the branch to the trunk, but so far we have to work only with the mentioned continual build. We will merge our branch after branching NetBeans 7.2 from trunk. This is also answer for the question, what release of NetBeans will contain the new JS support. It should be the release after NetBeans 7.2. I'm asking you whether you could play with the builds or better, could work in the builds with new JavaScript support and tell us every issue that you run in. It can be everything what doesn't fit you, something doesn't work as you expected, something is slow, you want change the behaviour of a feature etc. Your input / comments are very important for us and it will help us to achieve the new JavaScript support that you need.  The best way how to communicate issues is through our Bugzilla, because it is simple to track them. Sure you can write comment here:), but still I prefer Bugzilla for any issue. You can click here (you should be already log in Bugzilla), a form for the new JavaScript issue is opened, with pre-filled component Editor and NO72 keyword. I will write about the single features later, but now I will mentioned a few features that should work in better way than in the old support.  Syntactic and semantic colouring Navigator Mark Occurrences and GoTo Declaration  Code Completion Code Completion is invoked through keyboard shortcut CTRL+SPACE. The first invocation offers items that are found through a source model. Almost all editor features are based on the model, that is build from source code. There is a lot of work on the model yet, but it should offer better results. When the pop up window with code completion items is open and you press CTRL+SPACE again, then the code completion offers all elements that are in the project. In the pictures all elements that starts with letter 't'. Formatter with many options and more :) A few features are not still implemented that are supported in the old JavaScript support (for example jQuery support), but we are adding this features ASAP.

Quoting the Oracle® Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework11g Release 1 (11.1.1.4.0) documentatiom http://download.oracle.com/docs/cd/E17904_01/web.1111/b31973/ap_config.htm#BABFIGBA "When a request is sent to the server, a session timeout value is written to the page and the session timeout warning interval is defined by the context parameter  oracle.adf.view.rich.sessionHandling.WARNING_BEFORE_TIMEOUT. The user is given the opportunity to extend the session in a warning dialog, and a notification is sent when the session has expired and the page is refreshed. Depending on the application security configuration, the user may be redirected to the log in page when the session expires. Use the oracle.adf.view.rich.sessionHandling.WARNING_BEFORE_TIMEOUT context parameter to set the number of seconds prior to the session time out when a warning dialog is displayed. If the value of WARNING_BEFORE_TIMEOUT is less than 120 seconds, if client state saving is used for the page, or if the session has been invalidated, the feature is disabled. The session time-out value it taken directly from the session. Example A-3 shows configuration of the warning dialog to display at 120 seconds before the time-out of the session. Example A-3 Configuration of Session Time-out Warning <context-param>    <param-name>        oracle.adf.view.rich.sessionHandling.WARNING_BEFORE_TIMEOUT   </param-name>    <param-value>120</param-value> </context-param> The default value of this parameter is 120 seconds. To prevent notification of the user too frequently when the session time-out is set too short, the actual value of WARNING_BEFORE_TIMEOUT is determined dynamically, where the session time-out must be more than 2 minutes or the feature is disabled.

• Should I break contract early?

  - by cbang

  About 7 months ago I made the switch from a 5 year permie role (as a support developer in C#) to a contract role. I did this because I was stagnating in my old role. The extra cash contracting is really helping too. Unfortunately my team leader has taken a dislike to me from day 1. He regularly tells me I went out contracting too early, and frequently remarks that people in their 20's have no idea what they are talking about (I am 29). I was recently given the task of configuring our reports via our in house reporting library. It works off of a database driven criteria base, with controls being loaded as needed. The configs can get fairly complex, with controls having various levels of dependency on each other. I had a short time frame to get 50 reports working, and I was told to just get the basic configuration done, after which they will be handed over to the reporting team for fine tuning, then the test team. Our updated system was deployed 2 weeks ago, and it turned out that about 15 reports had issues causing incorrect data to be returned. Upon investigation I discovered that the reporting team hadn't even looked at them, and the test team hadn't bothered to test the reports. In spite of this, my team leader has told me that it is 100% my fault. As a result, our help desk got hit hard. I worked back until 2am that night to fix the highest priority issues (on my wedding anniversary!). The next day I arrive at work at 7:45 am to continue with the fixes. I got no thanks, but keep getting repeatedly told by my manager that "I fucked up" and "this is all my fault". I told my team leader I would spend part of my weekend working to fix the remaining issues. His response was "so you fucking should! you fucked it all up!" in front of the rest of the team. I responded "No worries." and left. I spent a decent chunk of my weekend working on it. Within 2 business days of finding out about the issues, I had all the medium and high priority issues fixed. The only comments my team leader has made to me in the last 2 weeks is to tell me how I have caused a big mess, and to tell me it was all my fault. I get this multiple times a day. If I make any jokes to anyone else in the team, I get told not to be a smartass... even though the rest of the team jokes throughout the day. Apart from that, all I get is angry looks any time I am anywhere near the guy. I don't give any response other than "alright" or silence when he starts giving me a hard time. Today we found out that the pilot release for the next stage has been pushed back. My team leader has said this was caused by me (but the higher ups said no such thing). He also said I have "no understanding of the ramifications of my actions". My question is, should I break contract (I am contracted until June 30) and find another role? No one else in my team will speak up in my favour, as they are contractors too and have no interest in rocking the boat. I could complain to my team leaders boss, but I can't see that helping, as I will still be stuck in the same team. As this is my first contract, I imagine getting the next one will be hard without a reference. I can't figure out if this guy is trying to get me fired up to provoke a confrontation (the guy loves conflict), or if he is just venting anger, or what. Copping this blame day after day is really wearing me down and making me depressed... especially since I have a wife and kid to support).

• Enterprise Integration: Can Companies Afford It?

  - by Ralph Wheaton

  Each year, my company holds a global sales conference where employees and partners from around the world some together to collaborate, share knowledge and ideas and learn about future plans.  As a member of the professional services division, several of us had been asked to make a presentation, an elevator pitch in 3 minutes or less that relates to a success we have worked on or directly relates to our tag (that is, our primary technology focus).  Mine happens to be Enterprise Integration as it relates Business Intelligence.  I found it rather difficult to present that pitch in a short amount of time and had to pare it down.  At any rate, in just a little over 3 minutes, this is the presentation I submitted.  Here is a link to the full presentation video in WMV format.   Many companies today subscribe to a buy versus build mentality in an attempt to drive down costs and improve time to implementation. Sometimes this makes sense, especially as it relates to specialized software or software that performs a small number of tasks extremely well. However, if not carefully considered or planned out, this oftentimes leads to multiple disparate systems with silos of data or multiple versions of the same data. For instance, client data (contact information, addresses, phone numbers, opportunities, sales) stored in your CRM system may not play well with Accounts Receivables. Employee data may be stored across multiple systems such as HR, Time Entry and Payroll. Other data (such as member data) may not originate internally, but be provided by multiple outside sources in multiple formats. And to top it all off, some data may have to be manually entered into multiple systems to keep it all synchronized. When left to grow out of control like this, overall performance is lacking, stability is questionable and maintenance is frequent and costly. Worse yet, in many cases, this topology, this hodgepodge of data creates a reporting nightmare. Decision makers are forced to try to put together pieces of the puzzle attempting to find the information they need, wading through multiple systems to find what they think is the single version of the truth. More often than not, they find they are missing pieces, pieces that may be crucial to growing the business rather than closing the business. across applications. Master data owners are defined to establish single sources of data (such as the CRM system owns client data). Other systems subscribe to the master data and changes are replicated to subscribers as they are made. This can be one way (no changes are allowed on the subscriber systems) or bi-directional. But at all times, the master data owner is current or up to date. And all data, whether internal or external, use the same processes and methods to move data from one place to another, leveraging the same validations, lookups and transformations enterprise wide, eliminating inconsistencies and siloed data. Once implemented, an enterprise integration solution improves performance and stability by reducing the number of moving parts and eliminating inconsistent data. Overall maintenance costs are mitigated by reducing touch points or the number of places that require modification when a business rule is changed or another data element is added. Most importantly, however, now decision makers can easily extract and piece together the information they need to grow their business, improve customer satisfaction and so on. So, in implementing an enterprise integration solution, companies can position themselves for the future, allowing for easy transition to data marts, data warehousing and, ultimately, business intelligence. Along this path, companies can achieve growth in size, intelligence and complexity. Truly, the question is not can companies afford to implement an enterprise integration solution, but can they afford not to.   Ralph Wheaton Microsoft Certified Technology Specialist Microsoft Certified Professional Developer Microsoft VTS-P BizTalk, .Net

• Copying A Slide From One Presentation To Another

  - by Tim Murphy

  There are many ways to generate a PowerPoint presentation using Open XML.  The first way is to build it by hand strictly using the SDK.  Alternately you can modify a copy of a base presentation in place.  The third approach to generate a presentation is to build a new presentation from the parts of an existing presentation by copying slides as needed.  This post will focus on the third option. In order to make this solution a little more elegant I am going to create a VSTO add-in as I did in my previous post.  This one is going to insert Tags to identify slides instead of NonVisualDrawingProperties which I used to identify charts, tables and images.  The code itself is fairly short. SlideNameForm dialog = new SlideNameForm(); Selection selection = Globals.ThisAddIn.Application.ActiveWindow.Selection;   if(dialog.ShowDialog() == DialogResult.OK) { selection.SlideRange.Tags.Add(dialog.slideName,dialog.slideName); } Zeyad Rajabi has a good post here on combining slides from two presentations.  The example he gives is great if you are doing a straight merge.  But what if you want to use your source file as almost a supermarket where you pick and chose slides and may even insert them repeatedly?  The following code uses the tags we created in the previous step to pick a particular slide an copy it to a destination file. using (PresentationDocument newDocument = PresentationDocument.Open(OutputFileText.Text,true)) { PresentationDocument templateDocument = PresentationDocument.Open(FileNameText.Text, false);   uniqueId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideMasterIdList); uint maxId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideIdList);   SlidePart oldPart = GetSlidePartByTagName(templateDocument, SlideToCopyText.Text);   SlidePart newPart = newDocument.PresentationPart.AddPart<SlidePart>(oldPart, "sourceId1");   SlideMasterPart newMasterPart = newDocument.PresentationPart.AddPart(newPart.SlideLayoutPart.SlideMasterPart);   SlideIdList idList = newDocument.PresentationPart.Presentation.SlideIdList;   // create new slide ID maxId++; SlideId newId = new SlideId(); newId.Id = maxId; newId.RelationshipId = "sourceId1"; idList.Append(newId);   // Create new master slide ID uniqueId++; SlideMasterId newMasterId = new SlideMasterId(); newMasterId.Id = uniqueId; newMasterId.RelationshipId = newDocument.PresentationPart.GetIdOfPart(newMasterPart); newDocument.PresentationPart.Presentation.SlideMasterIdList.Append(newMasterId);   // change slide layout ID FixSlideLayoutIds(newDocument.PresentationPart);     //newPart.Slide.Save(); newDocument.PresentationPart.Presentation.Save(); } The GetMaxIDFromChild and FixSlideLayoutID methods are barrowed from Zeyad’s article.  The GetSlidePartByTagName method is listed below.  It is really one LINQ query that finds SlideParts with child Tags that have the requested Name. private SlidePart GetSlidePartByTagName(PresentationDocument templateDocument, string tagName) { return (from p in templateDocument.PresentationPart.SlideParts where p.UserDefinedTagsParts.First().TagList.Descendants <DocumentFormat.OpenXml.Presentation.Tag>().First().Name == tagName.ToUpper() select p).First(); } This is what really makes the difference from what Zeyad posted.  The most powerful thing you can have when generating documents from templates is a consistent way of naming items to be manipulated.  I will be show more approaches like this in upcoming posts. del.icio.us Tags: Office Open XML,Presentation,PowerPoint,VSTO,TagList

• Free RAM disappears - Memory leak?

  - by Izzy

  On a fresh started system, free reports about 1.5G used RAM (8G RAM alltogether, Ubuntu 12.04 with lightdm and plasma desktop, one konsole window started). Having the apps running I use, it still consumes not more than 2G. However, having the system running for a couple of days, more and more of my free RAM disappears -- without showing up in the list of used apps: while smem --pie=name reports less than 20% used (and 80% being available), everything else says differently. free -m for example reports on about day 7: total used free shared buffers cached Mem: 7459 7013 446 0 178 997 -/+ buffers/cache: 5836 1623 Swap: 9536 296 9240 (so you can see, it's not the buffers or the cache). Today this finally ended with the system crashing completely: the windows manager being gone, apps "hanging in the air" (frameless) -- and a popup notifying me about "too many open files". Syslog reports: kernel: [856738.020829] VFS: file-max limit 752838 reached So I closed those applications I was able to close, and killed X using Ctrl-Alt-backspace. X tried to come up again after that with failsafeX, but was unable to do so as it could no longer detect its configuration. So I switched to a console using Ctrl-Alt-F2, captured all information I could think of (vmstat, free, smem, proc/meminfo, lsof, ps aux), and finally rebooted. X again came up with failsafeX; this time I told it to "recover from my backed-up configuration", then switched to a console and successfully used startx to bring up the graphical environment. I have no real clue to what is causing this issue -- though it must have to do either with X itself, or with some user processes running on X -- as after killing X, free -m output looked like this: total used free shared buffers cached Mem: 7459 2677 4781 0 62 419 -/+ buffers/cache: 2195 5263 Swap: 9536 59 9477 (~3.5GB being freed) -- to compare with the output after a fresh start: total used free shared buffers cached Mem: 7459 1483 5975 0 63 730 -/+ buffers/cache: 689 6769 Swap: 9536 0 9536 Two more helpful outputs are provided by memstat -u. Shortly before the crash: User Count Swap USS PSS RSS mail 1 0 200 207 616 whoopsie 1 764 740 817 2300 colord 1 3200 836 894 2156 root 62 70404 352996 382260 569920 izzy 80 177508 1465416 1519266 1851840 After having X killed: User Count Swap USS PSS RSS mail 1 0 184 188 356 izzy 1 1400 708 739 1080 whoopsie 1 848 668 826 1772 colord 1 3204 804 888 1728 root 62 54876 131708 149950 267860 And after a restart, back in X: User Count Swap USS PSS RSS mail 1 0 212 217 628 whoopsie 1 0 1536 1880 5096 colord 1 0 3740 4217 7936 root 54 0 148668 180911 345132 izzy 47 0 370928 437562 915056 Edit: Just added two graphs from my monitoring system. Interesting to see: everytime when there's a "jump" in memory consumption, CPU peaks as well. Just found this right now -- and it reminds me of another indicator pointing to X itself: Often when returning to my machine and unlocking the screen, I found something doing heavvy work on my CPU. Checking with top, it always turned out to be /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none. So after this long explanation, finally my questions: What could be the possible causes? How can I better identify involved processes/applications? What steps could be taken to avoid this behaviour -- short from rebooting the machine all X days? I was running 8.04 (Hardy) for about 5 years on my old machine, never having experienced the like (always more than 100 days uptime, before rebooting for e.g. kernel updates). This now is a complete new machine with a fresh install of 8.04. In case it matters, some specs: AMD A4-3400 APU with Radeon(tm) HD Graphics, using the open-source ati/radeon driver (so no fglrx installed), 8GB RAM, WDC WD1002FAEX-0 hdd (1TB), Asus F1A75-V Evo mainboard. Ubuntu 12.04 64-bit with KDE4/Plasma. Apps usually open more or less permanently include Evolution, Firefox, konsole (with Midnight Commander running inside, about 4 tabs), and LibreOffice -- plus occasionally Calibre, Gimp and Moneyplex (banking software I'm already using for almost 20 years now, in a version which did fine on Hardy).

• Why would Copying a Large Image to the Clipboard Freeze a Computer?

  - by Akemi Iwaya

  Sometimes, something really odd happens when using our computers that makes no sense at all…such as copying a simple image to the clipboard and the computer freezing up because of it. An image is an image, right? Today’s SuperUser post has the answer to a puzzled reader’s dilemna. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Original image courtesy of Wikimedia. The Question SuperUser reader Joban Dhillon wants to know why copying an image to the clipboard on his computer freezes it up: I was messing around with some height map images and found this one: (http://upload.wikimedia.org/wikipedia/commons/1/15/Srtm_ramp2.world.21600×10800.jpg) The image is 21,600*10,800 pixels in size. When I right click and select “Copy Image” in my browser (I am using Google Chrome), it slows down my computer until it freezes. After that I must restart. I am curious about why this happens. I presume it is the size of the image, although it is only about 6 MB when saved to my computer. I am also using Windows 8.1 Why would a simple image freeze Joban’s computer up after copying it to the clipboard? The Answer SuperUser contributor Mokubai has the answer for us: “Copy Image” is copying the raw image data, rather than the image file itself, to your clipboard. The raw image data will be 21,600 x 10,800 x 3 (24 bit image) = 699,840,000 bytes of data. That is approximately 700 MB of data your browser is trying to copy to the clipboard. JPEG compresses the raw data using a lossy algorithm and can get pretty good compression. Hence the compressed file is only 6 MB. The reason it makes your computer slow is that it is probably filling your memory up with at least the 700 MB of image data that your browser is using to show you the image, another 700 MB (along with whatever overhead the clipboard incurs) to store it on the clipboard, and a not insignificant amount of processing power to convert the image into a format that can be stored on the clipboard. Chances are that if you have less than 4 GB of physical RAM, then those copies of the image data are forcing your computer to page memory out to the swap file in an attempt to fulfil both memory demands at the same time. This will cause programs and disk access to be sluggish as they use the disk and try to use the data that may have just been paged out. In short: Do not use the clipboard for huge images unless you have a lot of memory and a bit of time to spare. Like pretty graphs? This is what happens when I load that image in Google Chrome, then copy it to the clipboard on my machine with 12 GB of RAM: It starts off at the lower point using 2.8 GB of RAM, loading the image punches it up to 3.6 GB (approximately the 700 MB), then copying it to the clipboard spikes way up there at 6.3 GB of RAM before settling back down at the 4.5-ish you would expect to see for a program and two copies of a rather large image. That is a whopping 3.7 GB of image data being worked on at the peak, which is probably the initial image, a reserved quantity for the clipboard, and perhaps a couple of conversion buffers. That is enough to bring any machine with less than 8 GB of RAM to its knees. Strangely, doing the same thing in Firefox just copies the image file rather than the image data (without the scary memory surge). Have something to add to the explanation? Sound off in the comments.

• Have Your Cake and Eat it Too: Industry Best Practices + Flexibility

  - by Oracle Accelerate for Midsize Companies

  By Richard Garraputa, VP of Sales & Marketing, brij Richard joined brij in 1996 after graduating from the University of North Carolina at Greensboro with degrees in Information Systems and Accounting. He directs brij’s overall strategies of both the business development and marketing departments. Companies looking for new ERP systems spend so much time comparing features and functions of software products but too often short change the value of their own processes.  Company managers I meet often claim that they are implementing a new ERP system so they can perform better and faster.  When asked how, the answer is often “by implementing best practices”.  But the term ‘best practices’ is frequently used to mean ‘doing things the way everyone else does them’ rather than a starting point or benchmark to build upon by adding your own value. Of course, implementing standardized processes across an enterprise is an important step in improving operational efficiencies.  But not all companies are alike.  Do you ever tell your customers “We are just like our competition and have no competitive differentiation”?  Probably not.  So why should the implementation of your business processes be just like your competitor’s?  Even within the same industry, companies differentiate themselves by leveraging their unique expertise and approach to business.  These unique aspects—the competitive differentiators that companies use to thrive in a crowded marketplace—can and should be supported by the implementation of business systems like ERP. Modern ERP systems like Oracle’s JD Edwards EnterpriseOne have a broad and deep functional footprint designed to integrate a company’s core operations.  But how can a company take advantage of this footprint without blowing up their implementation budget?  Some ERP vendors claim to solve this challenge by stating that their systems come pre-configured with ‘best practices’.  Too often what they are really saying is that you will have to abandon your key operational differentiators to fit a vendor’s template for your business—or extend your implementation and postpone the realization of any benefits. Thankfully for midsize companies, there is an alternative to the undesirable options of extended implementation projects or abandoning their competitive differentiators.  Oracle Accelerate Solutions speed the time it takes to implement JD Edwards EnterpriseOne solution based on your unique business characteristics, getting your new ERP system up and running faster without forcing your business to fit a cookie-cutter solution. We’ve been a JD Edwards implementation partner since 1986 and we now leverage Oracle Business Accelerators—cloud based rapid implementation tools built and maintained by Oracle. Oracle Business Accelerators deliver the benefits of embedded industry best practices without forcing every customer in to one set of processes like many template or “clone and go” approaches do. You retain the ability to reconfigure your applications—without customization—as your business changes. Wielded by Oracle partners with industry-specific domain expertise, Oracle Accelerate Solution implementations powered by Oracle Business Accelerators help automate the application configuration to fit your business better, faster. For example, on a recent project at a manufacturing company, the project manager told me that Oracle Business Accelerators helped get them to Conference Room Pilot 20% faster than with a traditional approach. Time savings equal cost savings. And if ‘better and faster’ is your goal for your business performance, shouldn’t it be the goal for your ERP implementation as well? Established in 1986, brij has been dedicated solely to helping its customers implement Oracle’s JD Edwards solutions and to maximize the value of those customers’ IT investments. They are a Gold level member in Oracle PartnerNetwork and an Oracle Accelerate Solution provider.

• DataContractSerializer: type is not serializable because it is not public?

  - by Michael B. McLaughlin

  I recently ran into an odd and annoying error when working with the DataContractSerializer class for a WP7 project. I thought I’d share it to save others who might encounter it the same annoyance I had. So I had an instance of  ObservableCollection<T> that I was trying to serialize (with T being a class I wrote for the project) and whenever it would hit the code to save it, it would give me: The data contract type 'ProjectName.MyMagicItemsClass' is not serializable because it is not public. Making the type public will fix this error. Alternatively, you can make it internal, and use the InternalsVisibleToAttribute attribute on your assembly in order to enable serialization of internal members - see documentation for more details. Be aware that doing so has certain security implications. This, of course, was malarkey. I was trying to write an instance of MyAwesomeClass that looked like this: [DataContract] public class MyAwesomeClass { [DataMember] public ObservableCollection<MyMagicItemsClass> GreatItems { get; set; }   [DataMember] public ObservableCollection<MyMagicItemsClass> SuperbItems { get; set; }     public MyAwesomeClass { GreatItems = new ObservableCollection<MyMagicItemsClass>(); SuperbItems = new ObservableCollection<MyMagicItemsClass>(); } }   That’s all well and fine. And MyMagicItemsClass was also public with a parameterless public constructor. It too had DataContractAttribute applied to it and it had DataMemberAttribute applied to all the properties and fields I wanted to serialize. Everything should be cool, but it’s not because I keep getting that “not public” exception. I could tell you about all the things I tried (generating a List<T> on the fly to make sure it wasn’t ObservableCollection<T>, trying to serialize the the Collections directly, moving it all to a separate library project, etc.), but I want to keep this short. In the end, I remembered my the “Debug->Exceptions…” VS menu option that brings up the list of exception-related circumstances under which the Visual Studio debugger will break. I checked the “Thrown” checkbox for “Common Language Runtime Exceptions”, started the project under the debugger, and voilà: the true problem revealed itself. Some of my properties had fairly elaborate setters whose logic I wanted to ignore. So for some of them, I applied an IgnoreDataMember attribute to them and applied the DataMember attribute to the underlying fields instead. All of which, in line with good programming practices, were private. Well, it just so happens that WP7 apps run in a “partial trust” environment and outside of “full trust”-land, DataContractSerializer refuses to serialize or deserialize non-public members. Of course that exception was swallowed up internally by .NET so all I ever saw was that bizarre message about things that I knew for certain were public being “not public”. I changed all the private fields I was serializing to public and everything worked just fine. In hindsight it all makes perfect sense. The serializer uses reflection to build up its graph of the object in order to write it out. In partial trust, you don’t want people using reflection to get at non-public members of an object since there are potential security problems with allowing that (you could break out of the sandbox pretty quickly by reflecting and calling the appropriate methods and cause some havoc by reflecting and setting the appropriate fields in certain circumstances. The fact that you cannot reflect your own assembly seems a bit heavy-handed, but then again I’m not a compiler writer or a framework designer and I have no idea what sorts of difficulties would go into allowing that from a compilation standpoint or what sorts of security problems allowing that could present (if any). So, lesson learned. If you get an incomprehensible exception message, turn on break on all thrown exceptions and try running it again (it might take a couple of tries, depending) and see what pops out. Chances are you’ll find the buried exception that actually explains what was going on. And if you’re getting a weird exception when trying to use DataContractSerializer complaining about public types not being public, chances are you’re trying to serialize a private or protected field/property.

• Java EE @ No Fluff Just Stuff Tour

  - by reza_rahman

  If you work in the US and still don't know what the No Fluff Just Stuff (NFJS) Tour is, you are doing yourself a very serious disfavor. NFJS is by far the cheapest and most effective way to stay up to date through some world class speakers and talks. This is most certainly true for US enterprise Java developers in particular. Following the US cultural tradition of old-fashioned roadshows, NFJS is basically a set program of speakers and topics offered at major US cities year round. Many now famous world class technology speakers can trace their humble roots to NFJS. Via NFJS you basically get to have amazing training without paying for an expensive venue, lodging or travel. The events are usually on the weekends so you don't need to even skip work if you want (a great feature for consultants on tight budgets and deadlines). I am proud to share with you that I recently joined the NFJS troupe. My hope is that this will help solve the lingering problem of effectively spreading the Java EE message here in the US. For NFJS I hope my joining will help beef up perhaps much desired Java content. In any case, simply being accepted into this legendary program is an honor I could have perhaps only dreamed of a few years ago. I am very grateful to Jay Zimmerman for seeing the value in me and the Java EE content. The current speaker line-up consists of the likes of Neal Ford, Venkat Subramaniam, Nathaniel Schutta, Tim Berglund and many other great speakers. I actually had my tour debut on April 4-5 with the NFJS New York Software Symposium - basically a short train commute away from my home office. The show is traditionally one of the smaller ones and it was not that bad for a start. I look forward to doing a few more in the coming months (more on that a bit later). I had four talks back to back (really my most favorite four at the moment). The first one was a talk on JMS 2 - some of you might already know JMS is one of my most favored Java EE APIs. The slides for the talk are posted below: What’s New in Java Message Service 2 from Reza Rahman The next talk I delivered was my Cargo Tracker/Java EE + DDD talk. This talk basically overviews DDD and describes how DDD maps to Java EE using code examples/demos from the Cargo Tracker Java EE Blue Prints project. Applied Domain-Driven Design Blue Prints for Java EE from Reza Rahman The third talk I delivered was our flagship Java EE 7/8 talk. As you may know, currently the talk is basically about Java EE 7. I'll probably slowly evolve this talk to gradually transform it into a Java EE 8 talk as we move forward (I'll blog about that separately shortly). The following is the slide deck for the talk: JavaEE.Next(): Java EE 7, 8, and Beyond from Reza Rahman My last talk for the show was my JavaScript+Java EE 7 talk. This talk is basically about aligning EE 7 with the emerging JavaScript ecosystem (specifically AngularJS). The slide deck for the talk is here: JavaScript/HTML5 Rich Clients Using Java EE 7 from Reza Rahman Unsurprisingly this talk was well-attended. The demo application code is posted on GitHub. The code should be a helpful resource if this development model is something that interests you. Do let me know if you need help with it but the instructions should be fairly self-explanatory. My next NFJS show is the Central Ohio Software Symposium in Columbus on June 6-8 (sorry for the late notice - it's been a really crazy few weeks). Here's my tour schedule so far, I'll keep you up-to-date as the tour goes forward: June 6 - 8, Columbus Ohio. June 24 - 27, Denver Colorado (UberConf) - my most extensive agenda on the tour so far. July 18 - 20, Austin Texas. I hope you'll take this opportunity to get some updates on Java EE as well as the other awesome content on the tour?

• Converting a PV vm back into an HVM vm

  - by wim.coekaerts

  I have been doing some Oracle VM benchmark stuff in the last week or 2 in my off hours and yesterday I wanted to convert one of my VMs that was based on a paravirt kernel into a vm that just boots as a regular hardware virt VM with a standard x86-64 kernel. It took me a little while to figure out the fastest way so now that I have it pretty much down I wanted to share the steps. A PV kernel uses pygrub and a paravirt kernel image that lives on the vm image virtual disk. since this disk image does not have to be bootable it doesn't contain a boot sector and if you just restart the VM in hvm mode the virtual bios will just not do much as it can't start the boot process from disk The first thing I do is make a backup of my vm.cfg file :-) and then edit it as follows : the original file contains : bootloader = '/usr/bin/pygrub' I replace that with : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' kernel = '/usr/lib/xen/boot/hvmloader' then changing the disk files. I change my xvd disks to hd disks and I copy over the iso image of my instal lDVD. In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

• IE9 and the Mystery of the Broken Video Tag

  - by David Wesst

  I was very excited when Microsoft released the Internet Explorer 9 Release Candidate. As far as I was concerned, this was another nail in the coffin for IE6 and step in the right direction for us .NET web developers as our base camp was finally starting to support the latest and greatest future-web standards. Unfortunately, my celebration was short lived as I soon hit a snag while loading up an HTML5 site I was building in Visual Studio 2010. The Mystery After updating Internet Explorer, I ran my HTML5 site that had the oh-so-lovely HTML5 video tag showing a video. Even though this worked in IE9 Beta, it appeared that IE9 RC could not load the same file. I figured that it was the video codec. Maybe IE9 RC no longer supported the video codec I used to encode my video. Here's the code I used: <video width="854" height="480" id="myOtherVideo" autoplay="" controls=""> <source src="/DemoSite1/Media/big_buck_bunny.mp4"/> <div> <p>Your browser does not support HTML5 Video.</p> </div> </video> As you can see from the code, I had the "fail-safe" code inside the video tag. The idea there being that if the video tag, or the video files themselves, are not supported by the browser my video should fail gracefully. What was even more strange was the fact that it worked in all the other HTML5 browsers that supported video. The Investigation Whoa! DJ stop the music. How can any of that make sense? Would the IE team really take such huge strides forward only to forget to include a feature that was already in the beta? I don't think so. I did plenty of searching on the web and asking around on the web, but could not seem to find anyone else having the same problem. Eventually I came across this post talking about declaring the MIME type in the .htaccess file. That got me thinking: does my web server support the video MIME type? I was using VS2010, so how do I know what kind of MIME types are supported by default? Still, my page hosted in Cassini (the web development server in VS2010) works on the other browsers. Why wouldn't it work with IE9 RC? To answer that, it was time to open up the upgraded toolbox known as the Developer's Tools in IE9 and use the new Network Tab. The Conclusion If you take a closer look at the results displayed from the Network tab, you can see that IE9 RC has interpreted the video file as text/html rather than video/mp4. To make this work, I decided to use IIS to debug my HTML5 web application by setting the web project's properties. Then, I added the MIME types that I want to support (i.e. video/mp4, video/ogg, video/webm). Et voila! The Mystery of the Broken Video Tag is solved. After Thoughts After solving the mystery, I still had the question about why my site worked in Chrome, Safari, and Firefox 3.6. After asking around, the best answer that I received was from my colleague Tyler Doerksen. He said that IE9 likely depends on the server telling it what kind of file it is downloading rather than trying to read the metadata about the data it is trying to download before doing anything. I have no facts to back this up, but it makes sense to me. In a browser war where milliseconds can make your browser fall back a few places in the race for supremacy, maybe the IE team opted to depend on the server knowing what kind of content it is serving up. Makes sense to me. In any case, that is just an educated guess. If you have any comments, feel free to post on them below. This post also appears at http://david.wes.st
