• Accessing JMX for Oracle WebLogic 11g

  - by Anthony Shorten

  In Oracle Utilities Application Framework V4, we use the latest Oracle WebLogic release (11g). The instructions below illustrate a way of allowing a console like jconsole to remotely monitor and manage Oracle WebLogic using the JMX Mbeans. Typically management of Oracle WebLogic is done from Oracle Enterprise Manager or the Oracle Weblogic console application but you can also use JMX. To access the JMX capability for Oracle WebLogic 11g, for an Oracle Utilities Application Framework based product, using a JMX console (such as jconsole) the following process needs to be performed: Enable the JMX Management Server in the Oracle WebLogic console at splapp - Configuration - General - Advanced Settings option. Enable both Compatibility Mbean Server Enabled and Management EJB Enabled (this enables the legacy and new JMX interface). Save the changes This change will require a restart. In the startup of the Oracle WebLogic server in the $SPLSYSTEMLOGS/myserver.log (or %SPLESYSTEMLOGS%\myserver.log on Windows) you will see the BEA-149512 message indicating the Mbean servers have been started. The message will indicate the JMX URL that can be used to access the JMX Mbeans. The URL is in the format: service:jmx:iiop://host:port/jndi/mbeanserver where: host - Oracle WebLogic host name port - Oracle WebLogic port number mbeanserver - Mbean Server to access. Valid Values: weblogic.management.mbeanservers.runtime weblogic.management.mbeanservers.edit weblogic.management.mbeanservers.domainruntime For illustrative purposes we will use the domainruntime Mbean. Ensure that you execute the splenviron[.sh] utility to set the appropriate environment variables for the desired environment. Execute the following jconsole command to initiate the connection to the JMX Mbean server Windows: jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;%WL_HOME%\server\lib\wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote Linux/Unix jconsole -J-Djava.class.path=$JAVA_HOME/lib/jconsole.jar;$WL_HOME/server/lib/wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote You will see a New Connection Dialog. Specify the URL from the previous steps into the Remote process (i.,e. service:jmx:iiop...). The credentials are the credentials specified for the Oracle WebLogic console. You are now able to view the JMX classes available. Here is an example from my demonstration machine: Refer to the Oracle WebLogic Mbean documentation to understand the output.

• Windows Azure Use Case: Fast Acquisitions

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Many organizations absorb, take over or merge with other organizations. In these cases, one of the most difficult parts of the process is the merging or changing of the IT systems that the employees use to do their work, process payments, and even get paid. Normally this means that the two companies have disparate systems, and several approaches can be used to have the two organizations use technology between them. An organization may choose to retain both systems, and manage them separately. The advantage here is speed, and keeping the profit/loss sheets separate. Another choice is to slowly “sunset” or stop using one organization’s system, and cutting to the other system immediately or at a later date. Although a popular choice, one of the most difficult methods is to extract data and processes from one system and import it into the other. Employees at the transitioning system have to be trained on the new one, the data must be examined and cleansed, and there is inevitable disruption when this happens. Still another option is to integrate the systems. This may prove to be as much work as a transitional strategy, but may have less impact on the users or the balance sheet. Implementation: A distributed computing paradigm can be a good strategic solution to most of these strategies. Retaining both systems is made more simple by allowing the users at the second organization immediate access to the new system, because security accounts can be created quickly inside an application. There is no need to set up a VPN or any other connections than just to the Internet. Having the users stop using one system and start with the other is also simple in Windows Azure for the same reason. Extracting data to Azure holds the same limitations as an on-premise system, and may even be more problematic because of the large data transfers that might be required. In a distributed environment, you pay for the data transfer, so a mixed migration strategy is not recommended. However, if the data is slowly migrated over time with a defined cutover, this can be an effective strategy. If done properly, an integration strategy works very well for a distributed computing environment like Windows Azure. If the Azure code is architected as a series of services, then endpoints can expose the service into and out of not only the Azure platform, but internally as well. This is a form of the Hybrid Application use-case documented here.

• Oracle anuncia resultados de Q3 FY10

  - by Paulo Folgado

  Oracle Reports GAAP EPS of $0.23, Non-GAAP EPS of $0.38New Software Licenses Up 13%, Applications New Licenses Up 21%Oracle Corporation today announced fiscal 2010 Q3 GAAP total revenues were up 17% to $6.4 billion, while non-GAAP total revenues were up 18% to $6.5 billion. Excluding the impact of Sun Microsystems, Inc., which Oracle acquired on January 26, 2010, GAAP total revenue grew 7%. GAAP new software license revenues were up 13% to $1.7 billion, and up 10% to $1.7 billion excluding Sun. GAAP software license updates and product support revenues were up 13% to $3.3 billion, while non-GAAP software license updates and product support revenues were up 12% to $3.3 billion. GAAP operating income was down 5% to $1.8 billion, and GAAP operating margin was 29%. Non-GAAP operating income was up 13% to $2.9 billion, and non-GAAP operating margin was 45%. GAAP net income was down 10% to $1.2 billion, while non-GAAP net income was up 9% to $1.9 billion. GAAP earnings per share were $0.23, down 11% compared to last year while non-GAAP earnings per share were up 9% to $0.38. GAAP operating cash flow on a trailing twelve-month basis was $8.2 billion. "Our solid top line growth, coupled with disciplined expense management, was key in generating $8.0 billion of free cash flow over the last twelve months," said Oracle CFO Jeff Epstein."The Sun integration is going even better than we expected," said Oracle President, Safra Catz. "We believe that Sun will make a significant contribution to our fourth quarter earnings per share as well as meet the profitability goals we set for next year.""Exadata is the fastest growing product in Oracle's history," said Oracle President, Charles Phillips. "Introduced a little over a year ago, the Exadata pipeline is now approaching $400 million with Q4 bookings forecast at nearly $100 million. This strengthens both sales growth and profitability in our Sun server and storage businesses.""Every quarter we grab huge chunks of market share from SAP," said Oracle CEO, Larry Ellison. "SAP's most recent quarter was the best quarter of their year, only down 15%, while Oracle's application sales were up 21%. But SAP is well ahead of us in the number of CEOs for this year, announcing their third and fourth, while we only had one."In addition, Oracle's Board of Directors declared a cash dividend of $0.05 per share of outstanding common stock to be paid to stockholders of record as of the close of business on April 14, 2010, with a payment date of May 5, 2010.

• OWB 11gR2 &ndash; Degenerate Dimensions

  - by David Allan

  Ever wondered how to build degenerate dimensions in OWB and get the benefits of slowly changing dimensions and cube loading? Now its possible through some changes in 11gR2 to make the dimension and cube loading much more flexible. This will let you get the benefits of OWB's surrogate key handling and slowly changing dimension reference when loading the fact table and need degenerate dimensions (see Ralph Kimball's degenerate dimensions design tip). Here we will see how to use the cube operator to load slowly changing, regular and degenerate dimensions. The cube and cube operator can now work with dimensions which have no surrogate key as well as dimensions with surrogates, so you can get the benefit of the cube loading and incorporate the degenerate dimension loading. What you need to do is create a dimension in OWB that is purely used for ETL metadata; the dimension itself is never deployed (its table is, but has not data) it has no surrogate keys has a single level with a business attribute the degenerate dimension data and a dummy attribute, say description just to pass the OWB validation. When this degenerate dimension is added into a cube, you will need to configure the fact table created and set the 'Deployable' flag to FALSE for the foreign key generated to the degenerate dimension table. The degenerate dimension reference will then be in the cube operator and used when matching. Create the degenerate dimension using the regular wizard. Delete the Surrogate ID attribute, this is not needed. Define a level name for the dimension member (any name). After the wizard has completed, in the editor delete the hierarchy STANDARD that was automatically generated, there is only a single level, no need for a hierarchy and this shouldn't really be created. Deploy the implementing table DD_ORDERNUMBER_TAB, this needs to be deployed but with no data (the mapping here will do a left outer join of the source data with the empty degenerate dimension table). Now, go ahead and build your cube, use the regular TIMES dimension for example and your degenerate dimension DD_ORDERNUMBER, can add in SCD dimensions etc. Configure the fact table created and set Deployable to false, so the foreign key does not get generated. Can now use the cube in a mapping and load data into the fact table via the cube operator, this will look after surrogate lookups and slowly changing dimension references.   If you generate the SQL you will see the ON clause for matching includes the columns representing the degenerate dimension columns. Here we have seen how this use case for loading fact tables using degenerate dimensions becomes a whole lot simpler using OWB 11gR2. I'm sure there are other use cases where using this mix of dimensions with surrogate and regular identifiers is useful, Fact tables partitioned by date columns is another classic example that this will greatly help and make the cube operator much more useful. Good to hear any comments.

• Check Your LIC Policy Status Through SMS

  - by Suganya

  Most of us in India hold at least one Life Insurance Policy today. While we all know everything gets computerized these days, LIC also supports payment via internet. You can view details about how payment is made through internet here. Few years back LIC started supporting SMS’es as well. Now you really don’t need to have internet rather check your LIC policy status while on road by sending just one SMS to 56677. Now that we know LIC answers to our SMS, lets see the format in which we have to send our SMS and their meaning. The format in which the SMS has to be sent is ASKLIC <Policy No> [PREMIUM/REVIVAL/BONUS/LOAN/NOM] Send any one of the following [PREMIUM/REVIVAL/BONUS/LOAN/NOM] to get the details. For instance, If you send ASKLIC <Policy No> Premium , it would return your Installment premium under policy ASKLIC <Policy No> Revival , it would check If policy is lapsed and return revival amount payable ASKLIC <Policy No> Bonus , it would check and return the amount of Bonus invested ASKLIC <Policy No> Loan , it would check and return the amount available as Loan ASKLIC <Policy No> NOM , it would check and return the details of Nomination Also, as everyone knows there are lots of pension schemes as well available in LIC and if one is interested in getting the pension details, then the format for sending the SMS is LICPension <Policy No> [STAT /ECDUE/ANNPD/PDTHRU/AMOUNT/CHQRET] For instance, If you send LICPension <Policy No> STAT gives you the IPP Policy status details LICPension <Policy No> ECDUE gives you the existence certificate due details LICPension <Policy No> ANNPD gives you the last annuity released date LICPension <Policy No> CHQ/ECS/NEFT (PDTHRU) gives the details about annuity payment through LICPension <Policy No> AMOUNT gives details about annuity amount LICPension <Policy No> CHQRET gives details about cheque return information Just with one SMS get all your policy details and make life easier. Each SMS that you send would be charged depending on your service provider. This article titled,Check Your LIC Policy Status Through SMS, was originally published at Tech Dreams.

• The Incremental Architect&acute;s Napkin &ndash; #3 &ndash; Make Evolvability inevitable

  - by Ralf Westphal

  Originally posted on: http://geekswithblogs.net/theArchitectsNapkin/archive/2014/06/04/the-incremental-architectacutes-napkin-ndash-3-ndash-make-evolvability-inevitable.aspxThe easier something to measure the more likely it will be produced. Deviations between what is and what should be can be readily detected. That´s what automated acceptance tests are for. That´s what sprint reviews in Scrum are for. It´s no small wonder our software looks like it looks. It has all the traits whose conformance with requirements can easily be measured. And it´s lacking traits which cannot easily be measured. Evolvability (or Changeability) is such a trait. If an operation is correct, if an operation if fast enough, that can be checked very easily. But whether Evolvability is high or low, that cannot be checked by taking a measure or two. Evolvability might correlate with certain traits, e.g. number of lines of code (LOC) per function or Cyclomatic Complexity or test coverage. But there is no threshold value signalling “evolvability too low”; also Evolvability is hardly tangible for the customer. Nevertheless Evolvability is of great importance - at least in the long run. You can get away without much of it for a short time. Eventually, though, it´s needed like any other requirement. Or even more. Because without Evolvability no other requirement can be implemented. Evolvability is the foundation on which all else is build. Such fundamental importance is in stark contrast with its immeasurability. To compensate this, Evolvability must be put at the very center of software development. It must become the hub around everything else revolves. Since we cannot measure Evolvability, though, we cannot start watching it more. Instead we need to establish practices to keep it high (enough) at all times. Chefs have known that for long. That´s why everybody in a restaurant kitchen is constantly seeing after cleanliness. Hygiene is important as is to have clean tools at standardized locations. Only then the health of the patrons can be guaranteed and production efficiency is constantly high. Still a kitchen´s level of cleanliness is easier to measure than software Evolvability. That´s why important practices like reviews, pair programming, or TDD are not enough, I guess. What we need to keep Evolvability in focus and high is… to continually evolve. Change must not be something to avoid but too embrace. To me that means the whole change cycle from requirement analysis to delivery needs to be gone through more often. Scrum´s sprints of 4, 2 even 1 week are too long. Kanban´s flow of user stories across is too unreliable; it takes as long as it takes. Instead we should fix the cycle time at 2 days max. I call that Spinning. No increment must take longer than from this morning until tomorrow evening to finish. Then it should be acceptance checked by the customer (or his/her representative, e.g. a Product Owner). For me there are several resasons for such a fixed and short cycle time for each increment: Clear expectations Absolute estimates (“This will take X days to complete.”) are near impossible in software development as explained previously. Too much unplanned research and engineering work lurk in every feature. And then pervasive interruptions of work by peers and management. However, the smaller the scope the better our absolute estimates become. That´s because we understand better what really are the requirements and what the solution should look like. But maybe more importantly the shorter the timespan the more we can control how we use our time. So much can happen over the course of a week and longer timespans. But if push comes to shove I can block out all distractions and interruptions for a day or possibly two. That´s why I believe we can give rough absolute estimates on 3 levels: Noon Tonight Tomorrow Think of a meeting with a Product Owner at 8:30 in the morning. If she asks you, how long it will take you to implement a user story or bug fix, you can say, “It´ll be fixed by noon.”, or you can say, “I can manage to implement it until tonight before I leave.”, or you can say, “You´ll get it by tomorrow night at latest.” Yes, I believe all else would be naive. If you´re not confident to get something done by tomorrow night (some 34h from now) you just cannot reliably commit to any timeframe. That means you should not promise anything, you should not even start working on the issue. So when estimating use these four categories: Noon, Tonight, Tomorrow, NoClue - with NoClue meaning the requirement needs to be broken down further so each aspect can be assigned to one of the first three categories. If you like absolute estimates, here you go. But don´t do deep estimates. Don´t estimate dozens of issues; don´t think ahead (“Issue A is a Tonight, then B will be a Tomorrow, after that it´s C as a Noon, finally D is a Tonight - that´s what I´ll do this week.”). Just estimate so Work-in-Progress (WIP) is 1 for everybody - plus a small number of buffer issues. To be blunt: Yes, this makes promises impossible as to what a team will deliver in terms of scope at a certain date in the future. But it will give a Product Owner a clear picture of what to pull for acceptance feedback tonight and tomorrow. Trust through reliability Our trade is lacking trust. Customers don´t trust software companies/departments much. Managers don´t trust developers much. I find that perfectly understandable in the light of what we´re trying to accomplish: delivering software in the face of uncertainty by means of material good production. Customers as well as managers still expect software development to be close to production of houses or cars. But that´s a fundamental misunderstanding. Software development ist development. It´s basically research. As software developers we´re constantly executing experiments to find out what really provides value to users. We don´t know what they need, we just have mediated hypothesises. That´s why we cannot reliably deliver on preposterous demands. So trust is out of the window in no time. If we switch to delivering in short cycles, though, we can regain trust. Because estimates - explicit or implicit - up to 32 hours at most can be satisfied. I´d say: reliability over scope. It´s more important to reliably deliver what was promised then to cover a lot of requirement area. So when in doubt promise less - but deliver without delay. Deliver on scope (Functionality and Quality); but also deliver on Evolvability, i.e. on inner quality according to accepted principles. Always. Trust will be the reward. Less complexity of communication will follow. More goodwill buffer will follow. So don´t wait for some Kanban board to show you, that flow can be improved by scheduling smaller stories. You don´t need to learn that the hard way. Just start with small batch sizes of three different sizes. Fast feedback What has been finished can be checked for acceptance. Why wait for a sprint of several weeks to end? Why let the mental model of the issue and its solution dissipate? If you get final feedback after one or two weeks, you hardly remember what you did and why you did it. Resoning becomes hard. But more importantly youo probably are not in the mood anymore to go back to something you deemed done a long time ago. It´s boring, it´s frustrating to open up that mental box again. Learning is harder the longer it takes from event to feedback. Effort can be wasted between event (finishing an issue) and feedback, because other work might go in the wrong direction based on false premises. Checking finished issues for acceptance is the most important task of a Product Owner. It´s even more important than planning new issues. Because as long as work started is not released (accepted) it´s potential waste. So before starting new work better make sure work already done has value. By putting the emphasis on acceptance rather than planning true pull is established. As long as planning and starting work is more important, it´s a push process. Accept a Noon issue on the same day before leaving. Accept a Tonight issue before leaving today or first thing tomorrow morning. Accept a Tomorrow issue tomorrow night before leaving or early the day after tomorrow. After acceptance the developer(s) can start working on the next issue. Flexibility As if reliability/trust and fast feedback for less waste weren´t enough economic incentive, there is flexibility. After each issue the Product Owner can change course. If on Monday morning feature slices A, B, C, D, E were important and A, B, C were scheduled for acceptance by Monday evening and Tuesday evening, the Product Owner can change her mind at any time. Maybe after A got accepted she asks for continuation with D. But maybe, just maybe, she has gotten a completely different idea by then. Maybe she wants work to continue on F. And after B it´s neither D nor E, but G. And after G it´s D. With Spinning every 32 hours at latest priorities can be changed. And nothing is lost. Because what got accepted is of value. It provides an incremental value to the customer/user. Or it provides internal value to the Product Owner as increased knowledge/decreased uncertainty. I find such reactivity over commitment economically very benefical. Why commit a team to some workload for several weeks? It´s unnecessary at beast, and inflexible and wasteful at worst. If we cannot promise delivery of a certain scope on a certain date - which is what customers/management usually want -, we can at least provide them with unpredecented flexibility in the face of high uncertainty. Where the path is not clear, cannot be clear, make small steps so you´re able to change your course at any time. Premature completion Customers/management are used to premeditating budgets. They want to know exactly how much to pay for a certain amount of requirements. That´s understandable. But it does not match with the nature of software development. We should know that by now. Maybe there´s somewhere in the world some team who can consistently deliver on scope, quality, and time, and budget. Great! Congratulations! I, however, haven´t seen such a team yet. Which does not mean it´s impossible, but I think it´s nothing I can recommend to strive for. Rather I´d say: Don´t try this at home. It might hurt you one way or the other. However, what we can do, is allow customers/management stop work on features at any moment. With spinning every 32 hours a feature can be declared as finished - even though it might not be completed according to initial definition. I think, progress over completion is an important offer software development can make. Why think in terms of completion beyond a promise for the next 32 hours? Isn´t it more important to constantly move forward? Step by step. We´re not running sprints, we´re not running marathons, not even ultra-marathons. We´re in the sport of running forever. That makes it futile to stare at the finishing line. The very concept of a burn-down chart is misleading (in most cases). Whoever can only think in terms of completed requirements shuts out the chance for saving money. The requirements for a features mostly are uncertain. So how does a Product Owner know in the first place, how much is needed. Maybe more than specified is needed - which gets uncovered step by step with each finished increment. Maybe less than specified is needed. After each 4–32 hour increment the Product Owner can do an experient (or invite users to an experiment) if a particular trait of the software system is already good enough. And if so, she can switch the attention to a different aspect. In the end, requirements A, B, C then could be finished just 70%, 80%, and 50%. What the heck? It´s good enough - for now. 33% money saved. Wouldn´t that be splendid? Isn´t that a stunning argument for any budget-sensitive customer? You can save money and still get what you need? Pull on practices So far, in addition to more trust, more flexibility, less money spent, Spinning led to “doing less” which also means less code which of course means higher Evolvability per se. Last but not least, though, I think Spinning´s short acceptance cycles have one more effect. They excert pull-power on all sorts of practices known for increasing Evolvability. If, for example, you believe high automated test coverage helps Evolvability by lowering the fear of inadverted damage to a code base, why isn´t 90% of the developer community practicing automated tests consistently? I think, the answer is simple: Because they can do without. Somehow they manage to do enough manual checks before their rare releases/acceptance checks to ensure good enough correctness - at least in the short term. The same goes for other practices like component orientation, continuous build/integration, code reviews etc. None of that is compelling, urgent, imperative. Something else always seems more important. So Evolvability principles and practices fall through the cracks most of the time - until a project hits a wall. Then everybody becomes desperate; but by then (re)gaining Evolvability has become as very, very difficult and tedious undertaking. Sometimes up to the point where the existence of a project/company is in danger. With Spinning that´s different. If you´re practicing Spinning you cannot avoid all those practices. With Spinning you very quickly realize you cannot deliver reliably even on your 32 hour promises. Spinning thus is pulling on developers to adopt principles and practices for Evolvability. They will start actively looking for ways to keep their delivery rate high. And if not, management will soon tell them to do that. Because first the Product Owner then management will notice an increasing difficulty to deliver value within 32 hours. There, finally there emerges a way to measure Evolvability: The more frequent developers tell the Product Owner there is no way to deliver anything worth of feedback until tomorrow night, the poorer Evolvability is. Don´t count the “WTF!”, count the “No way!” utterances. In closing For sustainable software development we need to put Evolvability first. Functionality and Quality must not rule software development but be implemented within a framework ensuring (enough) Evolvability. Since Evolvability cannot be measured easily, I think we need to put software development “under pressure”. Software needs to be changed more often, in smaller increments. Each increment being relevant to the customer/user in some way. That does not mean each increment is worthy of shipment. It´s sufficient to gain further insight from it. Increments primarily serve the reduction of uncertainty, not sales. Sales even needs to be decoupled from this incremental progress. No more promises to sales. No more delivery au point. Rather sales should look at a stream of accepted increments (or incremental releases) and scoup from that whatever they find valuable. Sales and marketing need to realize they should work on what´s there, not what might be possible in the future. But I digress… In my view a Spinning cycle - which is not easy to reach, which requires practice - is the core practice to compensate the immeasurability of Evolvability. From start to finish of each issue in 32 hours max - that´s the challenge we need to accept if we´re serious increasing Evolvability. Fortunately higher Evolvability is not the only outcome of Spinning. Customer/management will like the increased flexibility and “getting more bang for the buck”.

• Customization: It’s Wanted in Enterprise Tech Platforms Too

  - by Mike Stiles

  Did you know that every customer service person does their job the exact same way in every business organization?  And did you know that every business organization cares about the exact same metrics? I hope not, because both those things couldn’t be farther from the truth. And if there are different needs and approaches in different enterprises, it stands to reason technology platforms must become increasingly customizable. Oracle Social Cloud sees that coming and is doing something about it, at least in terms of social media management. Today we introduce Social Station, a customizable user experience workspace within the Oracle Social Relationship Management (SRM) platform. We think a lot about customer-centricity and customer experience around here, and we know our own customers are ready to start moving forward in being able to set up their work environments in the ways that work best for them. That kind of thing increases productivity, helps deliver on social objectives faster, and generally just makes life more pleasant. A recent IDG Enterprise report says that enterprises currently investing in more consumerized, easy-to-use technologies experience a 56% increase in employee productivity and a 46% increase in customer satisfaction. Imagine that. When you make it easier and more pleasant for employees to help customers, more customers get helped and everyone ends up happier. So what does this Social Station do and what does it mean, exactly? It’s an innovative move to take some pretty high-end tech (take a bow developers) and simplify it, making things more intuitive: Drag and drop lets you easily build out and personalize your social workspace with different modules. The new Custom Analytics module can mix and match over 120 metrics with thousands of customizable reporting options. You can check constantly refreshed updates and keep a real-time eye on the numbers you’re trying to move. One-click sharing and annotation in the Custom Analytics module improves sharing and collaboration across teams, departments and executives. Multi-view layout helps you leverage social insights by letting you monitor conversations by network, stream, metric, graph type, date range, and relative time period. The Enhanced Calendar is a better visual representation of content, posts, networks and views, letting you easily toggle between functions and views. The Oracle Social Station sets us up to always be developing & launching additional social modules for you, covering areas like content curation, influencer engagement, and command center creation. Oracle Social Cloud Group VP Meg Bear says, “Consumers today have high expectations of their technology application capabilities and usability, and those expectations don’t stop when they enter their workplaces.” In other words, internal enterprise technology platforms must reflect the personalization and customization being called for in consumer products and marketing. “One size fits all” is becoming an endangered concept. @mikestiles @oraclesocial

• SnagIt Live Writer Plug-in updated

  - by Rick Strahl

  I've updated my free SnagIt Live Writer plug-in again as there have been a few issues with the new release of SnagIt 11. It appears that TechSmith has trimmed the COM object and removed a bunch of redundant functionality which has broken the older plug-in. I also updated the layout and added SnagIt's latest icons to the form. Finally I've moved the source code to Github for easier browsing and downloading for anybody interested and easier updating for me. This plug-in is not new - I created it a number of years back, but I use the hell out it both for my blogging and for a few internal apps that with MetaWebLogApi to update online content. The plug-in makes it super easy to add captured image content directly into a post and upload it to the server. What does it do? Once installed the plug-in shows up in the list of plug-ins. When you click it launches a SnagIt Capture Dialog: Typically you set the capture settings once, and then save your settings. After that a single click or ENTER press gets you off capturing. If you choose the Show in SnagIt preview window option, the image you capture is is displayed in the preview editor to mark up images, which is one of SnagIt's great strengths IMHO. The image editor has a bunch of really nice effects for framing and marking up and highlighting of images that is really sweet. Here's a capture from a previous image in the SnagIt editor where I applied the saw tooth cutout effect: Images are saved to disk and can optionally be deleted immediately, since Live Writer creates copies of original images in its own folders before uploading the files. No need to keep the originals around typically. The plug-in works with SnagIt Versions 7 and later. It's a simple thing of course - nothing magic here, but incredibly useful at least to me. If you're using Live Writer and you own a copy of SnagIt do yourself a favor and grab this and install it as a plug-in.

• Emoti-phrases

  - by Tony Davis

  Surely the next radical step in the development of User-interface design is for applications to react appropriately to the rising tide of bewilderment, frustration or antipathy of the users. When an application understands that rapport is lost, it should respond accordingly. When we, for example, become confused by an unforgiving interface, shouldn't there be a way of signalling our bewilderment and having the application respond appropriately? There is surprisingly little in the current interface standards that would help. If we're getting frustrated with an unresponsive application, perhaps we could let it know of our increasing irritation by means of an "I'm getting angry and exasperated" slider. Although, by 'responding appropriately', I don't include playing a "we are experiencing unusually heavy traffic: your application usage is important to us" message, accompanied by calming muzak. When confronted with a tide of wizards, 'are you sure?' messages, or page-after-page of tiresome and barely-relevant options, how one yearns for a handy 'JFDI' (Just Flaming Do It) button. One click and the application miraculously desists with its annoying questions and just gets on with the job, using the defaults, or whatever we selected last time. Much more satisfying, and more direct to most developers and DBAs, however, would be the facility to communicate to the application via a twitter-style input field, or via parameters to command-line applications ("I don't want a wide-ranging debate with you; just open the bl**dy PDF!" or, or "Don't forget which of us has the close button"). Although to avoid too much cultural-dependence, perhaps we should take the lead from emoticons, and use a set of standardized emoti-phrases such as 'sez you', 'huh?', 'Pshaw!', or 'meh', which could be used to vent a range of feelings in any given application, whether it be SQL Server stubbornly refusing to give us the result we are expecting, or when an online-survey is getting too personal. Or a 'Lingua Glaswegia' perhaps: 'Atsabelter' ("very good") 'Atspish' ("must try harder") 'AnThenYerArsFellAff ' ("I don't quite trust these results") 'BileYerHeid' or 'ShutYerGub' ("please stop these inane questions") There would, of course, have to be an ANSI standards body to define the phrases that were acceptable. Presumably, there would be a tussle amongst the different international standards organizations. Meanwhile Oracle, Microsoft and Apple would each release non-standard extensions. Time then, surely, to plant emoti-phrases on the lot of them and develop a user-driven consensus. Send us your suggestions! The best one will win an iPod nano! Cheers! Tony.

• Inside Red Gate - Divisions

  - by Simon Cooper

  When I joined Red Gate back in 2007, there were around 80 people in the company. Now, around 3 years later, it's grown to more than 200. It's a constant battle against Dunbar's number; the maximum number of people you can keep track of in a social group, to try and maintain that 'small company' feel that attracted myself and so many others to apply in the first place. There are several strategies the company's developed over the years to try and mitigate the effects of Dunbar's number. One of the main ones has been divisionalisation. Divisions The first division, .NET, appeared around the same time that I started in 2007. This combined the development, sales, marketing and management of the .NET tools (then, ANTS Profiler v3) into a separate section of the office. The idea was to increase the cohesion and communication between the different people involved in the entire lifecycle of the tools; from initial product development, through to marketing, then to customer support, who would feed back to the development team. This was such a success that the other development teams were re-worked around this model in 2009. Nowadays there are 4 divisions - SQL Tools, DBA, .NET, and New Business. Along the way there have been various tweaks to the details - the sales teams have been merged into the divisions, marketing and product support have been (mostly) centralised - but the same basic model remains. So, how has this helped? As Red Gate has continued to grow over the years, divisionalisation has turned Red Gate from a monolithic software company into what one person described as a 'federation of small businesses'. Each division is free to structure itself as it sees fit, it's free to decide what to concentrate development work on, organise its own newsletters and webinars, decide its own release schedule. Each division is its own small business. In terms of numbers, the size of each division varies from 20 people (.NET) to 52 (SQL Tools); well below Dunbar's number. From a developer's perspective, this means organisational structure is very flat & wide - there's only 2 layers between myself and the CEOs (not that it matters much; everyone can go and have a chat to Neil or Simon, or anyone else inbetween, whenever they want. Provided you can catch them at their desk!). As Red Gate grows, and expands into new areas, new divisions will be created as needed, old ones merged or disbanded, but the division structure will help to maintain that small-company feel that keeps Red Gate working as it does.

• Add a Cache Clearing Button to Firefox

  - by Asian Angel

  While emptying your browser’s cache may not be something that you need to worry with often or at all there are times when clearing it can be helpful. The Empty Cache Button extension lets you have instant on-demand cache clearing in Firefox. Some reasons why you might want or need to clear your browser’s cache: Clear out older (or out of date) versions of images, etc. from your favorite websites Free up disk space Clearing the cache may help fix browser behavior issues Help protect privacy (i.e. images, etc. displayed within a personal account) Before For our example we loaded three webpages in order to add content to our browser’s cache. Using the “CacheViewer” we were able to easily see the contents of our browser’s cache after the webpages finished loading. What if you need to clear your cache immediately without restarting your browser (if the options are set to empty the cache on browser exit)? Note: CacheViewer is available via a separate extension and can be found here. Empty Cache Button in Action Once you install the extension all that you need to do is right click on any of your browser’s toolbars and select “Customise”. Drag the “Toolbar Button” to an appropriate location in your browser’s UI and you are ready to go. To clear your browser’s cache simply click the button…that is all there is to it. When the cache is empty you will see this small message window appear in the lower right corner of your “Desktop”. Opening up the “CacheViewer” again shows that everything has been cleared out. Terrific! Conclusion If you ever find yourself needing to clear your browser’s cache immediately then the Empty Cache Button extension provides an easy way to do so without restarting your browser (if the options are set to empty the cache on browser exit).

As Oracle has continued to acquire new companies and technologies, it has become essential that we also create a single, unified language and approach for implementation - across the Oracle ecosystem.With the release of OUM 5.1 in 2009, OUM provided full support for all enterprise application implementation projects including Oracle E-Business Suite R12, Siebel CRM, PeopleSoft Enterprise, and JD Edwards EnterpriseOne projects. In 2010, we released OUM training that supports the use of OUM on these types of projects.That support represented a major milestone in the evolution of OUM and enabled implementers to transition to OUM. Consequently, we announced a staggered retirement schedule for Oracle's legacy methods. On January 31, 2011 we announced the retirement of:Oracle Application Implementation Method (AIM)Oracle AIM for Business Flows (ABF)Siebel Results RoadmapLater this year, we will announce the retirement of Compass - the legacy PeopleSoft method - and Data Warehouse Method Fast Track.OUM is available free of charge to Oracle Gold, Platinum, and Diamond partners through the Oracle Partner Network (OPN) [OUM on OPN]. The OUM Customer Program allows customers to obtain copies of the method for their internal use by contracting with Oracle for an engagement of two weeks or longer meeting some additional minimum criteria.There be more retirement announcements in the coming months. For now it's "Adios AIM." Thanks for the memories...

• Shutdown Hangs for 5 Minutes on Kubuntu 14.04

  - by Augustinus

  I've had persistent problems with a 5 minute hang at shutdown for the last three versions of Kubuntu (13.04, 13.10, and now 14.04). I suspect this is not a KDE-specific problem. Recently, I performed a fresh installation of Kubuntu 14.04 from a live-USB, and shutdown worked normally for about a week. The hang-up is now happening again, and I can't figure out why. A brief description of the problem: The hang-up occurs with all methods of initiating a normal shutdown: Clicking the shutdown or restart button in KDE, sudo shutdown -h now, sudo reboot The shutdown splash screen appears. Using the down-arrow to access verbose messages, I see "Asking all remaining processes to terminate." This message remains for 5 minutes with no disk activity. Finally, a rapid series of messages flurries to the screen: * All processes ended within 300 seconds... [ OK ] nm-dispatcher.action: Caught signal 15, shutting down... ModemManager[852]: <warn> Could not acquire the 'org.freedesktop.ModemManager1' service name ModemManager[852]: <info> ModemManager is shut down * Deactivating swap... [ OK ] * Unmounting local filesystems... [ OK ] * Will now restart` Possible Sources of the Problem: Before the problem re-appeared, I have mainly been doing routine computing. I have kept the system up-to-date using apt-get upgrade and apt-get dist-upgrade. The only other notable incident was a power failure. I do not have the computer connected to a UPS, so the power failure resulted in an immediate shutdown. Could this have corrupted an important file which must be accessed at shutdown? Is there any way that could cause a 5-minute hang-up? Here is a list of packages that have been updated before the problem appeared: bash iotop dpkg dpkg-dev python3-software-properties libdpkg-perl software-properties-kde software-properties-common akonadi-backend-mysql libakonadiprotocolinternals1 akonadi-server firefox-locale-en firefox flashplugin-installer libqapt2 libqapt2-runtime thunderbird openjdk-7-jre-headless thunderbird-locale-en kubuntu-driver-manager qapt-deb-installer openjdk-7-jre qapt-batch icedtea-7-jre-jamvm libelf1 dpkg dpkg-dev libdpkg-perl libjbig0 gettext-base libgettextpo-dev libssl1.0.0 libgettextpo0 libasprintf-dev linux-headers-3.13.0-24 gettext libasprintf0c2 linux-headers-3.13.0-24-generic openssl linux-libc-dev gstreamer0.10-qapt kubuntu-desktop linux-image-extra-3.13.0-24-generic linux-image-3.13.0-24-generic I would appreciate any help with this.

• Oracle VM Deep Dives

  - by rickramsey

  "With IT staff now tasked to deliver on-demand services, datacenter virtualization requirements have gone beyond simple consolidation and cost reduction. Simply provisioning and delivering an operating environment falls short. IT organizations must rapidly deliver services, such as infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). Virtualization solutions need to be application-driven and enable:" "Easier deployment and management of business critical applications" "Rapid and automated provisioning of the entire application stack inside the virtual machine" "Integrated management of the complete stack including the VM and the applications running inside the VM." Application Driven Virtualization, an Oracle white paper That was published in August of 2011. The new release of Oracle VM Server delivers significant virtual networking performance improvements, among other things. If you're not sure how virtual networks work or how to use them, these two articles by Greg King and friends might help. Looking Under the Hood at Virtual Networking by Greg King Oracle VM Server for x86 lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to. Greg King explains how you go about doing this, and how Oracle VM Server for x86 implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs. Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86. Fundamental Concepts of VLAN Networks by Greg King and Don Smerker Oracle VM Server for x86 supports a wide range of options in network design, varying in complexity from a single network to configurations that include network bonds, VLANS, bridges, and multiple networks connecting the Oracle VM servers and guests. You can create separate networks to isolate traffic, or you can configure a single network for multiple roles. Network design depends on many factors, including the number and type of network interfaces, reliability and performance goals, the number of Oracle VM servers and guests, and the anticipated workload. The Oracle VM Manager GUI presents four different ways to create an Oracle VM network: Bonds and ports VLANs Both bond/ports and VLANS A local network This article focuses the second option, designing a complex Oracle VM network infrastructure using only VLANs, and it steps through the concepts needed to create a robust network infrastructure for your Oracle VM servers and guests.
