  • A tour of the GlassFish 3.1.2 DCOM support

    - by alexismp
    While we've mentioned the DCOM support in GlassFish 3.1.2 several times before, you'll probably find Byron's DCOM blog entry to be useful if you're using Windows as a deployment platform for your GlassFish cluster. Byron discusses how DCOM is used to communicate with remote Windows nodes participating in a GlassFish cluster, what Java libraries were used to wrap around DCOM, what new asadmin commands were addd (in particular validate-dcom) as well as some tips to make this all work on your specific environment. In addition to this blog post, you should considering reading the official product documentation : • Considerations for Using DCOM for Centralized Administration • Setting Up DCOM and Testing the DCOM Set Up

  • Generating an EJB SDO Service Interface for Oracle SOA Suite by Edwin Biemond

    - by JuergenKress
    In Oracle SOA Suite you can use the EJB adapter as a reference or service in your composite applications. The EJB adapter has a flexible binding integration, there are 3 ways for integrating the remote interface with your composite. First you have the java interface way which I described here this follows the JAX-WS way. It means you need to use Calendar for your Java date types and leads to one big WSDL when you add a wire to a service component. Read the full article here.

  • How and where do you store your private work/sourcecode?

    - by Amir Rezaei
    I have worked as a developer for over 10 years now. During that time I have had my own small projects where I have developed tools, applications and games. I have not found any robust solution to store my work. It’s always fun to get back to your code and see how you did before and how you would do it now. It’s just work that is unfortunate to lose. There are SVN solution such as Google’s Project Hosting. However I’m not interested in sharing my code or making it open source. Currently I’m hosting my own SVN server. So here comes my question: How and where do you store your private work/sourcecode? Requirements: Sourcecode versioning Backup Prefers free Edit: Remote access Edit: I have used Dropbox + TrueCrypt + SVN. Unfortunately you are limited to 5gb.

  • How to configure apache / php / postfix website emails when using vhosts?

    - by Alistair Buxton
    I have a LAMP webserver configured to serve multiple websites. Each virtual host has various PHP applications, mainly Wordpress. When users sign up to the Wordpress sites, email is sent by PHP through to postfix, and then on to the receiver. The problem is that postfix is identifying itself to the remote server with the contents of /etc/hostname, which is not a fully qualified domain name. Some mail servers reject this and the mail bounces. Additionally, the return path is being set to one of the vitual host domains, seemingly at random. I could set /etc/hostname to one of the website domain names, but then the emails from the other websites would have a wrong server in the headers, and this would not fix the return-path issue. Possibly related, apache2 says "could not determine the server's fully qualified domain name" on startup. How do I fix this so that each website can send email without revealing the other websites hosted on the server?

  • Accessibility bus warning when opening files in Eclipse from command line (Ubuntu 13.10)

    - by Reese
    Similar to closed issue Gnome Menu Broken? When opening a file from the command line for edits in Eclipse , I get this warning: ** (eclipse:nnnn): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. The 4-digit number at (eclipse:nnnn) changes each time I issue an 'eclipse some/file.ext' command. The file opens but the warning is an annoyance that shouldn't be happening, it may be indicative of some other problem. Updated Ubuntu 13.10 64-bit, updated Eclipse Luna.

Breakneck Speed. Lightning Fast. Perhaps even overwhelming. No matter which set of adjectives we use to describe it, social media’s rise into the enterprise mainstream has been unprecedented. Indeed, the big 4 social media powerhouses (Facebook, Google+, LinkedIn, and Twitter), have nearly 2 Billion users between them. You may be asking (as you should really) “That’s all well and good for the consumer, but for me at my company, what’s your point? Beyond the fact that I can check and post updates, that is.” Good question, kind sir. Impact of Social and Collaboration on Project Management I’ll dovetail this discussion to the project management realm, since that’s what I’m writing about. Speed is a big challenge for project-driven organizations. Anything that can help speed up project delivery - be it a new product introduction effort or a geographical expansion project - fast is a good thing. So where does this whole social thing fit particularly since there are already a host of tools to help with traditional project execution? The fact is companies have seen improvements in their productivity by deploying departmental collaboration and other social-oriented solutions. McKinsey’s survey on social tools shows we have reached critical scale: 72% of respondents report that their companies use at least one and over 40% say they are using social networks and blogs. We don’t hear as much about the impact of social media technologies at the project and project manager level, but that does not mean there is none. Consider the new hire. The type of individual entering the workforce and executing on projects is a generation of worker expecting visually appealing, easy to use and easy to understand technology meshing hand-in-hand with business processes. Consider the project manager. The social era has enhanced the role that the project manager must play. Today’s project manager must be a supreme communicator, an influencer, a sympathizer, a negotiator, and still manage to keep all stakeholders in the loop on project progress. Social tools play a significant role in this effort. Now consider the impact to the project team. The way that a project team functions has changed, with newer, social oriented technologies making the process of information dissemination and team communications much more fluid. It’s clear that a shift is occurring where “social” is intersecting with project management. The Rise of Social Project Management We refer to the melding of project management and social networking as Social Project Management. Social Project Management is based upon the philosophy that the project team is one part of an integrated whole, and that valuable and unique abilities exist within the larger organization. For this reason, Social Project Management systems should be integrated into the collaborative platform(s) of an organization, allowing communication to proceed outside the project boundaries. What makes social project management "social" is an implicit awareness where distributed teams build connected links in ways that were previously restricted to teams that were co-located. Just as critical, Social Project Management embraces the vision of seamless online collaboration within a project team, but also provides for, (and enhances) the use of rigorous project management techniques. Social Project Management acknowledges that projects (particularly large projects) are a social activity - people doing work with people, for other people, with commitments to yet other people. The more people (larger projects), the more interpersonal the interactions, and the more social affects the project. The Epitome of Social - Fusion Project Portfolio Management If I take this one level further to discuss Fusion Project Portfolio Management, the notion of Social Project Management is on full display. With Fusion Project Portfolio Management, project team members have a single place for interaction on projects and access to any other resources working within the Fusion ERP applications. This allows team members the opportunity to be informed with greater participation and provide better information. The application’s the visual appeal, and highly graphical nature makes it easy to navigate information. The project activity stream adds to the intuitive user experience. The goal of productivity is pervasive throughout Fusion Project Portfolio Management. Field research conducted with Oracle customers and partners showed that users needed a way to stay in the context of their core transactions and yet easily access social networking tools. This is manifested in the application so when a user executes a business process, they not only have the transactional application at their fingertips, but also have things like e-mail, SMS, text, instant messaging, chat – all providing a number of different ways to interact with people and/or groups of people, both internal and external to the project and enterprise. But in the end, connecting people is relatively easy. The larger issue is finding a way to serve up relevant, system-generated, actionable information, in real time, which will allow for more streamlined execution on key business processes. Fusion Project Portfolio Management’s design concept enables users to create project communities, establish discussion threads, manage event calendars as well as deliver project based work spaces to organize communications within the context of a project – all within a secure business environment. We’d love to hear from you and get your thoughts and ideas about how Social Project Management is impacting your organization.

  • How to ensure custom serverListener events fires before action events

    - by frank.nimphius
    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} Using JavaScript in ADF Faces you can queue custom events defined by an af:serverListener tag. If the custom event however is queued from an af:clientListener on a command component, then the command component's action and action listener methods fire before the queued custom event. If you have a use case, for example in combination with client side integration of 3rd party technologies like HTML, Applets or similar, then you want to change the order of execution. The way to change the execution order is to invoke the command item action from the client event method that handles the custom event propagated by the af:serverListener tag. The following four steps ensure your successful doing this 1.       Call cancel() on the event object passed to the client JavaScript function invoked by the af:clientListener tag 2.       Call the custom event as an immediate action by setting the last argument in the custom event call to true function invokeCustomEvent(evt){   evt.cancel();          var custEvent = new AdfCustomEvent(                         evt.getSource(),                         "mycustomevent",                                                                                                                    {message:"Hello World"},                         true);    custEvent.queue(); } 3.       When handling the custom event on the server, lookup the command item, for example a button, to queue its action event. This way you simulate a user clicking the button. Use the following code ActionEvent event = new ActionEvent(component); event.setPhaseId(PhaseId.INVOKE_APPLICATION); event.queue(); The component reference needs to be changed with the handle to the command item which action method you want to execute. 4.       If the command component has behavior tags, like af:fileDownloadActionListener, or af:setPropertyListener, defined, then these are also executed when the action event is queued. However, behavior tags, like the file download action listener, may require a full page refresh to be issued to work, in which case the custom event cannot be issued as a partial refresh. File download action tag: http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_fileDownloadActionListener.html " Since file downloads must be processed with an ordinary request - not XMLHttp AJAX requests - this tag forces partialSubmit to be false on the parent component, if it supports that attribute." To issue a custom event as a non-partial submit, the previously shown sample code would need to be changed as shown below function invokeCustomEvent(evt){   evt.cancel();          var custEvent = new AdfCustomEvent(                         evt.getSource(),                         "mycustomevent",                                                                                                                    {message:"Hello World"},                         true);    custEvent.queue(false); } To learn more about custom events and the af:serverListener, please refer to the tag documentation: http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_serverListener.html

    I love the Mythbusters television show.  That has to be one of the coolest jobs in the world…it involves investigation, problem solving, science, trial & error, searching for the truth, robotics and remote controls, and in the end, you usually get to blow stuff up.  How great is that?!  I know I’ll never forget the episode where they blew up a cement truck.  That was truly awesome. Well, perhaps not quite made for TV, but pretty cool nonetheless, Paul Randal (@PaulRandal) has been doing some SQL Server myth busting here in the month of April with his DBA Myth a Day series.  It starts with In-Flight Transactions Continue After a Failover.  Check it out!

  • How can I send audio input as chunked HTTP?

    - by Noli
    I am trying to create an interface with an external server, and don't know where to start. I would need to take audio as input to my computer, and send it to the remote server as a chunked HTTP request. The api that i'm trying to connect to is described here p1-5 http://dragonmobile.nuancemobiledeveloper.com/public/Help/HttpInterface/HTTP_Services_for_NDEV_v1.2_Silver_Version.pdf I have never worked with audio programmatically, so don't know what would be the most straighforward way to go about this? Are there solutions that exist out there that already do this? I've come across references to Shoutcast, VLC, Icecast, FFMPeg, Darkice, but I don't know if those are appropriate for what I'm trying to accomplish or not. Would appreciate any guidance, Thanks

  • 2nd instance of Firefox does not obey GTK2 customizations

    - by Cocoro Cara
    Hi On Ubuntu 10.10 I started a 2nd instance of Firefox using the command: $ firefox -ProfileManager -no-remote & Created a new profile and everything works smoothly except for the fact that this instance of FF does not obey by GTK2 customizations that I have placed in ~/.gtkrc-2.0 Moreover, only SOME of the customizations are not obeyed. For example, the vertical scrollbars are supposed to be on the left, but they are on the right. The scrollbar arrows are together (Mac-like) as specified, so is the scrollbar width. The first instance obeys all customizations with scrollbars on the left. Any ideas?

  • How to access shared folders from file editors?

    - by Marchosius
    I am running a xampp server on one of my other computers, and when using the brows functionality from text editors like gedit, bluefish and Eclipse/Aptana studio I can access the shares I made for the sites running on the server. Even when I right click-edit with-application with the the file browser it does not open the file in the editor. How can get this to work without having to copy the file over from the share then edit and then upload again after I am done? Similar issue when trying to upload a file to hosting server direct from the file server I have with filezilla. with this I also need to copy the file over to my pc and then from there upload to the hosting server with filezilla. EDIT: For eclipse I found a build in functionality to do this. (new-remote system connection-Enter the access details) Nothing yet on FileZilla Hope my Question is clear

  • Cannot escape character '@' in fstab file

    - by ubuntico
    I want to attach remote FTP directory as a local directory in my system. I will use curlftpfs line in the fstab file , but to login I have to pass my user name and password. The user name has a special character (@) and it needs to be escaped via octal ascii code. The octal ascii for '@' is 100. But when I try to enter the following into the FSTAB file, curlftpfs#myself\100myself.com:ftpPassword@ftp://ftp.mysite.com /mnt/somedir I get an error saying Error connecting to ftp: Couldn't resolve host 'myself.com:ftpPassword@ftp://ftp.mysite.com' The fstab does not recognize escaped symbol @ (\100) and thinks that the FTP site should start immediately after the @ symbol (just like I haven't escaped it). Can someone help? Why I cannot escape @, when it can be done for space character, for example?

  • How do I efficiently code both the client and server at the same time?

    - by liamzebedee
    I'm coding my game using a client-server model. When playing on singleplayer, the game starts a local server, and interacts with it just like a remote server (multiplayer). I have done this to avoid coding separate singleplayer and multiplayer code. I have just started coding and have encountered a major problem. Currently I'm developing the game in Eclipse, having all the game classes organized into packages. Then, in my server code, I just use all the classes in the client packages. The problem is, these client classes have variables that are specific to rendering, which obviously wouldn't be performed on a server. Should I create modified versions of the client classes to use in the server? Or should I just modify the client classes with a boolean, to indicate if its the client/server using it. Are there any other options I have? I just had a thought about maybe using the server class as the core class, then extending it with rendering stuff?

  • Benchmarking MySQL Replication with Multi-Threaded Slaves

    - by Mat Keep
    0 0 1 1145 6530 Homework 54 15 7660 14.0 Normal 0 false false false EN-US JA X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:Cambria; mso-ascii-font-family:Cambria; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Cambria; mso-hansi-theme-font:minor-latin; mso-ansi-language:EN-US;} The objective of this benchmark is to measure the performance improvement achieved when enabling the Multi-Threaded Slave enhancement delivered as a part MySQL 5.6. As the results demonstrate, Multi-Threaded Slaves delivers 5x higher replication performance based on a configuration with 10 databases/schemas. For real-world deployments, higher replication performance directly translates to: · Improved consistency of reads from slaves (i.e. reduced risk of reading "stale" data) · Reduced risk of data loss should the master fail before replicating all events in its binary log (binlog) The multi-threaded slave splits processing between worker threads based on schema, allowing updates to be applied in parallel, rather than sequentially. This delivers benefits to those workloads that isolate application data using databases - e.g. multi-tenant systems deployed in cloud environments. Multi-Threaded Slaves are just one of many enhancements to replication previewed as part of the MySQL 5.6 Development Release, which include: · Global Transaction Identifiers coupled with MySQL utilities for automatic failover / switchover and slave promotion · Crash Safe Slaves and Binlog · Optimized Row Based Replication · Replication Event Checksums · Time Delayed Replication These and many more are discussed in the “MySQL 5.6 Replication: Enabling the Next Generation of Web & Cloud Services” Developer Zone article  Back to the benchmark - details are as follows. Environment The test environment consisted of two Linux servers: · one running the replication master · one running the replication slave. Only the slave was involved in the actual measurements, and was based on the following configuration: - Hardware: Oracle Sun Fire X4170 M2 Server - CPU: 2 sockets, 6 cores with hyper-threading, 2930 MHz. - OS: 64-bit Oracle Enterprise Linux 6.1 - Memory: 48 GB Test Procedure Initial Setup: Two MySQL servers were started on two different hosts, configured as replication master and slave. 10 sysbench schemas were created, each with a single table: CREATE TABLE `sbtest` (    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,    `k` int(10) unsigned NOT NULL DEFAULT '0',    `c` char(120) NOT NULL DEFAULT '',    `pad` char(60) NOT NULL DEFAULT '',    PRIMARY KEY (`id`),    KEY `k` (`k`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 10,000 rows were inserted in each of the 10 tables, for a total of 100,000 rows. When the inserts had replicated to the slave, the slave threads were stopped. The slave data directory was copied to a backup location and the slave threads position in the master binlog noted. 10 sysbench clients, each configured with 10 threads, were spawned at the same time to generate a random schema load against each of the 10 schemas on the master. Each sysbench client executed 10,000 "update key" statements: UPDATE sbtest set k=k+1 WHERE id = <random row> In total, this generated 100,000 update statements to later replicate during the test itself. Test Methodology: The number of slave workers to test with was configured using: SET GLOBAL slave_parallel_workers=<workers> Then the slave IO thread was started and the test waited for all the update queries to be copied over to the relay log on the slave. The benchmark clock was started and then the slave SQL thread was started. The test waited for the slave SQL thread to finish executing the 100k update queries, doing "select master_pos_wait()". When master_pos_wait() returned, the benchmark clock was stopped and the duration calculated. The calculated duration from the benchmark clock should be close to the time it took for the SQL thread to execute the 100,000 update queries. The 100k queries divided by this duration gave the benchmark metric, reported as Queries Per Second (QPS). Test Reset: The test-reset cycle was implemented as follows: · the slave was stopped · the slave data directory replaced with the previous backup · the slave restarted with the slave threads replication pointer repositioned to the point before the update queries in the binlog. The test could then be repeated with identical set of queries but a different number of slave worker threads, enabling a fair comparison. The Test-Reset cycle was repeated 3 times for 0-24 number of workers and the QPS metric calculated and averaged for each worker count. MySQL Configuration The relevant configuration settings used for MySQL are as follows: binlog-format=STATEMENT relay-log-info-repository=TABLE master-info-repository=TABLE As described in the test procedure, the slave_parallel_workers setting was modified as part of the test logic. The consequence of changing this setting is: 0 worker threads:    - current (i.e. single threaded) sequential mode    - 1 x IO thread and 1 x SQL thread    - SQL thread both reads and executes the events 1 worker thread:    - sequential mode    - 1 x IO thread, 1 x Coordinator SQL thread and 1 x Worker thread    - coordinator reads the event and hands it to the worker who executes 2+ worker threads:    - parallel execution    - 1 x IO thread, 1 x Coordinator SQL thread and 2+ Worker threads    - coordinator reads events and hands them to the workers who execute them Results Figure 1 below shows that Multi-Threaded Slaves deliver ~5x higher replication performance when configured with 10 worker threads, with the load evenly distributed across our 10 x schemas. This result is compared to the current replication implementation which is based on a single SQL thread only (i.e. zero worker threads). Figure 1: 5x Higher Performance with Multi-Threaded Slaves The following figure shows more detailed results, with QPS sampled and reported as the worker threads are incremented. The raw numbers behind this graph are reported in the Appendix section of this post. Figure 2: Detailed Results As the results above show, the configuration does not scale noticably from 5 to 9 worker threads. When configured with 10 worker threads however, scalability increases significantly. The conclusion therefore is that it is desirable to configure the same number of worker threads as schemas. Other conclusions from the results: · Running with 1 worker compared to zero workers just introduces overhead without the benefit of parallel execution. · As expected, having more workers than schemas adds no visible benefit. Aside from what is shown in the results above, testing also demonstrated that the following settings had a very positive effect on slave performance: relay-log-info-repository=TABLE master-info-repository=TABLE For 5+ workers, it was up to 2.3 times as fast to run with TABLE compared to FILE. Conclusion As the results demonstrate, Multi-Threaded Slaves deliver significant performance increases to MySQL replication when handling multiple schemas. This, and the other replication enhancements introduced in MySQL 5.6 are fully available for you to download and evaluate now from the MySQL Developer site (select Development Release tab). You can learn more about MySQL 5.6 from the documentation  Please don’t hesitate to comment on this or other replication blogs with feedback and questions. Appendix – Detailed Results

  • Live Meeting error: malformed email address... or IS IT???

    - by PeterBrunone
    During a remote SharePoint training session this morning, Live Meeting presented one of our instructors with the following gem:  "An attendee email address is malformed".  This was particularly troubling since a wizard took care of adding all the entries, and they looked correct (even after being sifted through my character analysis tool).As it turns out, the addresses were indeed correct.  As sometimes happens, though, at the line breaks, it looked like there was no space between the semicolon and the following email address.  Since I'm a member in good standing of the "I wonder what this button does" school of thought, I added an extra space after each of these cramped little semicolons -- and the invitation executed flawlessly.Coincidence?  Maybe... but you can bet I'm going to keep trying dumb stuff like that when the error message doesn't make sense.  Think of it as the tech support equivalent of "Ask a silly question..."

    I had no internship a few months ago, so I basically went on a 'resume mailing' spree and emailed a lot of companies that I was interested in working for and that had my line of work. This didn't prove futile until a company accepted me into their internship program but said that I would be working remotely. I had no problem with that, the project was good and I was interested. Now I have another internship at a company that is close to my home and I don't want to miss it at all! I can manage both internships side-by-side. In the day, I will do the internship that is closer to my home and at night (and other times), I can manage the remote internship. My question is -- should I both? I am particularly interested in how two internships at the same time are viewed. Would it look good or bad? PS: Neither is paying me anything, so money is not a factor.

  • Cloud availability of short-term "virgin" Windows instances?

    - by Thorbjørn Ravn Andersen
    I have a situation where we on a regular basis need a freshly installed "virgin" Windows installation to do various work in isolation on, and building one from scratch every time in a vmware instance is getting tedious. Perhaps there are cloud offerings providing a service allowing to request one or more Windows instances and after a very short while they were available for logging in through Remote Desktop? After usage they were just recycled without having to pay for a full Windows license every time. Do this exist for a reasonable price? What is your personal experiences with this?

  • Information about SATA, IDE (PATA) controllers

    - by Adam Matan
    I have a remote computer on which I want to install a new hard drive for rsync backup. The problem is, I don't know what controller technology is used (PATA, SATA, SATA2, ...) and how many available slots are left. I want to spare me an unnecessary drive just for opening the chassis and looking into wires. How do I query the SATA or PATA controllers? I'm interested in the following points: Which controllers exist in the machine How many (and which) disks are attached to each controller How many available slots are there
