• Oracle Traffic Director – download and check out new cool features in 11.1.1.7.0 by Frances Zhao

  - by JuergenKress

  As Oracle's strategic layer-7 software load balancer product, Oracle Traffic Direct is fast, reliable, secure, easy-to-use and scalable; that you can deploy as the reliable entry point for all TCP, HTTP and HTTPS traffic to application servers and web servers in your network. The latest release Oracle Traffic Director 11.1.1.7.0 is available for ExaLogic and Database Appliance! For download and details please visit the Traffic Director OTN website. It this release, we have introduced some major new functionality and improvements. Web application firewall. Oracle Traffic Director supports web application firewalls. A web application firewall (WAF) is a filter or server plugin that applies a set of rules, called rule sets, to an HTTP request. Using a web application firewall, users can inspect traffic and deny requests to protect back-end applications from CSRF vulnerabilities and common attacks such as cross-site scripting. WebSocket Connections. Oracle Traffic Director handles WebSocket connections by default. WebSocket connections are long-lived and allow support for live content, games in real-time, video chatting, and so on. Support for LDAP/T3 Load Balancing. Oracle Traffic Director now supports basic LDAP/T3 load balancing at layer 7, where requests are handled as generic TCP connections for traffic tunneling. It works in full-NAT mode. Please download and try it out. For more information, check out the data sheet and the documentation.

• How do you manage a complexity jump?

  - by glenatron

  It seems an infrequent but common experience that sometimes you're working on a project and suddenly something turns up unexpectedly, throws a massive spanner in the works and ramps up the complexity a whole lot. For example, I was working on an application that talked to SOAP services on various other machines. I whipped up a prototype that worked fine, then went on to develop a regular front end and generally get everything up and running in a nice, fairly simple and easy to follow fashion. It worked great until we started testing across a wider network and suddenly pages started timing out as the latency of the connections and the time required to perform calculations on remote machines resulted in timed out requests to the soap services. It turned out that we needed to change the architecture to spin requests out onto their own threads and cache the returned data so it could be updated progressively in the background rather than performing calculations on a request by request basis. The details of that scenario are not too important - indeed it's not a great example as it was quite forseeable and people who have written a lot of apps of this type for this type of environment might have anticipated it - except that it illustrates a way that one can start with a simple premise and model and suddenly have an escalation of complexity well into the development of the project. What strategies do you have for dealing with these types of functional changes whose need arises - often as a result of environmental factors rather than specification change - later on in the development process or as a result of testing? How do you balance between avoiding the premature optimisation/ YAGNI/ overengineering risks of designing a solution that mitigates against possible but not necessarily probable issues as opposed to developing a simpler and easier solution that is likely to be as effective but doesn't incorporate preparedness for every possible eventuality?

• Release/Change management - best aproach

  - by Bob Rivers

  I asked this question an year ago in StackOverflow and never got a good answer. Since Programmers seems to be a better place to ask it, I'll give it a try... What is the better way to work with release management? More specifically what would be the best way to release packages? For example, assuming that you have a relatively stable system, a good quality assurance process (QA), etc. How do you prefer to release new versions? Let's assume that we are talking about a mid to large "centralized" web system (no clients), in-house development. This system can be considered "vital" for a corporate operations. I have a tendency to prefer to do this by releasing packets at regular intervals, not greater than 1 to 3 months. During this period, I will include into the package,fixes and improvements and make the implementation in production environment only once. But I've seen some people who prefer to place small changes in production, but with a greater frequency. The claim of these people is that by doing so, it is easier to identify bugs that have gone through the process of QA: in a package with 10 changes and another with only 1, it is much easier to know what caused the problem in the package with just one change... What is the opinion came from you?

• ClearTrace Supports Statement Level Events

  - by Bill Graziano

  One of the requests I get on a regular basis is to capture the performance of statement level events.  The latest beta has this feature available.  If you’re interested in this I’d like to get some feedback. I handle the SP:StmtCompleted and the SQL:StmtCompleted events.  These report CPU, reads, writes and duration. I’m not in any way saying it’s a good idea to trace these events.  Use with caution as this can make your traces much larger. If there are statement level events in the trace file they will be processed.  However the query screen displays batch level *OR* statement level events.  If it did both we’d be double counting. I don’t have very many traces with statement completed events in them.  That means I only did limited testing of how it parses these events.  It seems to work well so far though.  Your feedback is appreciated. If you ever write loops or cursors in stored procedures you’re going to get huge trace files.  Be warned. I also fixed an annoying bug where ClearTrace would fail and tell you a value had already been added.  This is a result of the collection I use being case-sensitive and SQL Server not being case-sensitive.  I thought I had properly coded around that but finally realized I hadn’t.  It should be fixed now. If you have any questions or problems the ClearTrace support forum is the best place for those.

• 12.04 GPU lockup

  - by soandos

  I was able to install Ubuntu 12.04 using the alternative version of the image, (64 bit) but when I start the system it tells me the GPU locked up, and instead presents a text only screen. I understand that this site is not for bug reports, but at the same time, I know that there are some versions of the installer than have to be compatible with my graphics card (Nvidia GTS 360M). I assumed that the mere fact that the alternative installer ran was an indication that I could get some sort of graphical interface running after the install. Is there some way of getting some type of graphical interface running on my machine? Even better would be is there a way to get the rest of the system running as normal (i.e. GPU up and running)? If an internet connection is required to download driver support or something similar, directions for how to configure a wireless connection with WPA2-Personal protection from the text-only interface (bash). Any help would be appreciated. Note: I was able to find this which tells me that the card is supported. Note 2: In the install software stage of the install, I was unable to install anything (no internet connection) Update: The exact error message is [8.591394] [drm] 0000:01:00.0: GPU Lockup - switching to software fbcon Update 2: If I try to install with the regular version of Ubuntu, the screen goes staticy. This also happens if I install with Wubi (distasteful I know) and then try to use Ubuntu. Update 3: I've tried xforcevesa, nomodeset and xforcevesa nomodeset as my wubi boot options. Update 4: Thanks to jokerdino, I can now connect to the internet, so internet tools would now be a possibility.

• Undeploy multiple SOA composites with WLST or ANT by Danilo Schmiedel

  - by JuergenKress

  As part of our current project the Build Management team asked for a solution to undeploy multiple composites at one time. Of course you have the “Undeploy All from This Partition” menu option in Enterprise Manager but since we have a lot of deployments every day the guys wanted to have a script solution. It is even more important for the nightly deployments on our continuous integration environment – strange, we couldn’t find anybody who wants to do the undeployment via Enterprise Manager manually every night ;-) However with WLST or ANT the SOA Suite comes with two options to undeploy composites via script. In this article I’d like to explain you both ways. Undeployment with WLST You can test the steps below on Oracle's Pre-built Virtual Machine for SOA Suite and BPM Suite 11g. Change to the WLST directory under MIDDLEWARE_HOME/Oracle_SOA1/common/bin. cd /oracle/fmwhome/Oracle_SOA1/common/bin/ Open WLST ./wlst.sh Connect to the SOA server Read the full article by Danilo Schmiedel SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit  www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

• SQL Saturday #274 Slovenia

  - by Dejan Sarka

  Yes, here it is SQL Saturday #274 is coming to Slovenia (#sqlsatSlovenia). The event will take place on Saturday, December 21st, at company pixi* labs, Informacijske tehnologije, d.o.o. Poslovna cona A 2 SI-4208 Šencur This company generously offered to host the event. We, the whole Slovenian SQL Server community, are very grateful for this. At this time, a call for speakers went out, and we are already getting the first proposals. We are especially happy that we will get possibility to show the foreign speakers how beautiful Slovenia and especially the capital Ljubljana is in December. Expect a lot of partying right on the streets, no matter of weather. Be prepared, we have slightly weird customs when it comes to drinks. For example, our regular special discount offer is not three drinks for the price of two; it is six drinks for the price of five. If you are a speaker or want to become one, consider sending a proposal. Since most of the sessions will be held in English and you don’t want to speak, consider coming as a visitor as well. Or maybe you would be interested to become a sponsor. Although we are targeting a low budgeted event, any kind of sponsorship is very welcome. Please feel free to contact the organizers if you are interested to become a sponsor: Matija Lah – [email protected], Mladen Prajdic - [email protected], or Dejan Sarka  - [email protected]. Looking forward to see you all!

• Adaptive Case Management Modeling with CMMN by Jessica Ray

  - by JuergenKress

  A new version of Oracle BPM Suite 11.1.1.7 with Adaptive Case Management (ACM) is now available, so what will that mean for requirements gathering? BPM project requirements can be documented using Business Process Model and Notation (BPMN 2.0). For ACM, there is a new notation in the works. It is called Case Management Model and Notation (CMMN). For now, this notation isn’t included as a modeling tool in the new version of Oracle BPM Suite 11.1.1.7 with ACM, but it is possible that a modeling tool could be included in a future release. What is CMMN? CMMN is a standard intended to capture the common elements that Case Management Products use, the same way that BPMN is a standard for BPM products (such as Oracle BPM). CMMN is created by the Object Management Group (OMG) and is still in the beta version. In April 2014, OMG released the second beta version the CMMN 1.0, and the most recent version is available here. CMMN captures some of the elements that are commonly used when talking about ACM such as Cases, Milestones, and Tasks. It also introduces some elements that you may not automatically hear when talking about ACM such as Stages, Events, and Decorators. Here is a quick summary at a few (but not all) of the elements of CMMN taken from the CMMN spec. A Few CMMN Elements Read the complete article here SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

• Most effective work habit for coding? [on hold]

  - by Cris

  Working on a big solo project (~15,000 LOC), I am encountering the following phenomenon: I seem to work best when I program in short bursts of 10-15 minutes. Right now I am working on a section which is a complete first time for me architecturally and if I have any architectural issues that emerge when doing the implementation, I seem to be able to best serve these by taking a total break. Then, later, sketching out the ideas on some paper. And when I feel I have sufficient clarity, then going back to code. This iterates until that architectural issue for that section is resolved. This seems quite counter intuitive: that I can progress more quickly by coding less, and taking more breaks. I am nearing the end of the sections which are "first times" for me, and about to dive into stuff which I am much more familiar and am wondering if this counter intuitive efficiency will continue. So my question is: even for regular coding of sections one is familiar with, which don't require constant re-clarification of the best architecture, is more progress to be attained by taking more breaks and coding in bursts?

• How to structure git repositories for project?

  - by littledynamo

  I'm working on a content synchronisation module for Drupal. There is a server module, which sits on ona website and exposes content via a web service. There is a also a client module, which sits on a different site and fetches and imports the content at regular intervals. The server is created on Drupal 6. The client is created on Drupal 7. There is going to be a need for a Druapl 7 version of the server. And then there will be a need for a Drupal 8 version of both the client and the server once it is released next year. I'm fairly new to git and source control, so I was wondering what is the best way to setup the git repositories? Would it be a case of having a separate repository for each instance, i.e: Drupal 6 server = 1 repository Drupal 6 client = 1 repository Drupal 7 server = 1 repository Drupal 7 client = 1 repository etc Or would it make more sense to have one repository for the server and another for the client then create branches for each Drupal version? Currently I have 2 repositories - one for the client and another for the server.

• Developer momentum on open source projects

  - by sashang

  Hi I've been struggling to develop momentum contributing to open source projects. I have in the past tried with gcc and contributed a fix to libstdc++ but it was a once off and even though I spent months in my spare time on the dev mailing list and reading through things I just never seemed to develop any momentum with the code. Eventually I unsubscribed and got my free time back and uncluttered my mailbox. Like a lot of people I have some little open source defunct projects lying around on the net, but they're not large and I'm the only contributor. At the moment I'm more interested in contributing to a large open source project and want to know how people got started because I find it difficult while working full time to develop any momentum with the code base. Other more regular contributors, who are on the project full-time, are able to make changes at will and as result enter that positive feedback cycle where they understand the code and also know where it's heading. It makes the barrier to entry higher for those that come along later. My questions are to people who actively contribute to large opensource projects, like the Linux kernel, or gcc or clang/llvm or anything else with say a developer head count of more than 10. How did you get started? Was there a large chunk of time in your life that you just could dedicate to working on the project? I know in Linus's case he had a chunk of time (6 months) to get it started. What barriers to entry did you encounter? Can you describe the initial stages of the time spent with the project, from when you had little understanding of the code to when you understood enough to commit regularly. Thanks

• It's Raining Solaris Training

  - by rajeshr

  That the popularity of Solaris 11 is only growing is clear from how regular the training sessions have been around this product. It's such an excitement to be going around sharing knowledge on Solaris, more so to explore the nitty gritty of many new and evolving features. Trust me, it's only getting better! In the process, just like in the past I stumbled on several individuals, each teaching me a lesson or two. I'm grateful. And if I've managed to get over the laziness to come back to the web logs with a collection of class photos from the last couple of months, it's because of a sense of gratitude to all 'em in the picture below. Solaris 11 Network Administration Pilot Teach in Bangalore. Sun Identity Manager (n.k.a Oracle Waveset IDM) Deployment Fundamentals Training. I'm missing from the snap because these delegates sat well over 10,000 Kms away from where I taught this class from, but were kind enough to help me associate a face with the voice by sending me a group photograph. If you want to attend one such OU program cutting down the travel, try OU's Live Virtual Class (a.k.a LVC) . Transition to Solaris 11 in Mumbai. Solaris 11 Advanced Administration Session in Bangalore. Transition to Solaris 11 in Mumbai. Attending Gary Riseborough's Exadata Training at Singapore. Solaris 11 Advanced Administration Session in Bangalore. If only the participants of each LVC session belonged to the same location, there would've been additional three group photographs occupying this space! Thank you everyone for many many memorable moments.

• organization of DLL linked functions

  - by m25

  So this is a code organization question. I got my basic code working but when I expand it will be terrible. I have a DLL that I don't have a .lib for. Therefore I have to use the whole loadLibrary()/getprocaddress() combo. it works great. But this DLL that i'm referencing at 100+ functions. my current process is (1) typedef a type for the function. or typedef short(_stdcall *type1)(void); then (2) assign a function name that I want to use such as type1 function_1, then (3) I do the whole LoadLibrary, then do something like function_1 = (type1)GetProcAddress(hinstLib, "_mangled_funcName@5"); normally I would like to do all of my function definitions in a header file but because I have to do use the load library function, its not that easy. the code will be a mess. Right now i'm doing (1) and (2) in a header file and was considering making a function in another .cpp file to do the load library and dump all of the (3)'s in there. I considered using a namespace for the functions so I can use them in the main function and not have to pass over to the other function. Any other tips on how to organize this code to where it is readable and organized? My goals are to be able to use function_1 as a regular function in the main code. if I have to a ref::function_1 that would be okay but I would prefer to avoid it. this code for all practical purposes is just plane C at the moment. thanks in advance for any advice!

• How can rotating release managers improve a project's velocity and stability?

  - by Yannis Rizos

  The Wikipedia article on Parrot VM includes this unreferenced claim: Core committers take turns producing releases in a revolving schedule, where no single committer is responsible for multiple releases in a row. This practice has improved the project's velocity and stability. Parrot's Release Manager role documentation doesn't offer any further insight into the process, and I couldn't find any reference for the claim. My first thoughts were that rotating release managers seems like a good idea, sharing the responsibility between as many people as possible, and having a certain degree of polyphony in releases. Is it, though? Rotating release managers has been proposed for Launchpad, and there were some interesting counterarguments: Release management is something that requires a good understanding of all parts of the code and the authority to make calls under pressure if issues come up during the release itself The less change we can have to the release process the better from an operational perspective Don't really want an engineer to have to learn all this stuff on the job as well as have other things to take care of (regular development responsibilities) Any change of timezones of the releases would need to be approved with the SAs and: I think this would be a great idea (mainly because of my lust for power), but I also think that there should be some way making sure that a release manager doesn't get overwhelmed if something disastrous happens during release week, maybe by have a deputy release manager at the same time (maybe just falling back to Francis or Kiko would be sufficient). The practice doesn't appear to be very common, and the counterarguments seem reasonalbe and convincing. I'm quite confused on how it would improve a project's velocity and stability, is there something I'm missing, or is this just a bad edit on the Wikipedia article? Worth noting that the top voted answer in the related "Is rotating the lead developer a good or bad idea?" question boldly notes: Don't rotate.

• What's the best practice to do SOA exception handling?

  - by sun1991

  Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful to do when they occur. Any attempt to bake such capabilities into the client creates an inordinate degree of coupling between the client and the object, raising serious design questions. How could the client possibly know more about the error than the service, unless it is tightly coupled to it? What if the error originated several layers below the service—should the client be coupled to those lowlevel layers? Should the client try the call again? How often and how frequently? Should the client inform the user of the error? Is there a user? By having all service exceptions be indistinguishable from one another, WCF decouples the client from the service. The less the client knows about what happened on the service side, the more decoupled the interaction will be. On the other side, here's what my colleague suggest: I believe it’s simply incorrect, as it does not align with best practices in building a service oriented architecture and it ignores the general idea that there are problems that users are able to recover from, such as not keying a value correctly. If we considered only systems exceptions, perhaps this idea holds, but systems exceptions are only part of the exception domain. User recoverable exceptions are the other part of the domain and are likely to happen on a regular basis. I believe the correct way to build a service oriented architecture is to map user recoverable situations to checked exceptions, then to marshall each checked exception back to the client as a unique exception that client application programmers are able to handle appropriately. Marshall all runtime exceptions back to the client as a system exception, along with the stack trace so that it is easy to troubleshoot the root cause. I'd like to know what you think about this? Thank you.

• Are web application usability issues equal to website usability issues?

  - by Kor

  I've been reading two books about web usability issues and tests (Rocket Surgery Made Easy¹ and Prioritizing Web Usability²) and they claim some strategies and typical problems about website usability and how to lead them. However, I want to do a web application, and I think I lost track of what I am trying to solve. These two books claim to work with raw websites (e-commerce, business sites, even intranet), but I'm not sure if everything about web usability is applicable to web application usability. They sure talk about always having available (and usable) the Back button, to focus on short information rather than big amounts of text, etc., but they could be inaccurate in deeper problems that may be easier (or just skippable) in regular websites. Has anybody some experience in this field and could tell me if both web applications and websites share their usability issues? Thanks in advance Edit: Quoting Wikipedia, a website is a collection of related web pages containing images, videos or other digital assets, and a web application is an application that is accessed over a network such as the Internet or an intranet. To sum up, both shows/lets you search/produce information but websites are "simple" in interaction and keep the classics of websites (one-click actions) and the other one is closer to desktop applications in the meaning of their uses and ways of interaction (double click, modal windows, asynchronous calls [to keep you in the same "environment" instead of reloading it] etc.). I don't know if this clarifies the difference. Edit 2: Quoting @Victor and myself, a website is anything running in your browser, but a web application is somewhat running in your browser that could be running in your desktop, with similar behaviors and features. Gmail is a web application that could replace Outlook. GDocs could replace Office. Grooveshark could replace your music player, etc.

• Script/tool to import series of snapshots, each being a new edition, into GIT, populating source tree?

  - by Rob

  I've developed code locally and taken a fairly regular snapshot whenever I reach a significant point in development, e.g. a working build. So I have a long-ish list of about 40 folders, each folder being a snapshot e.g. in ascending date YYYYMMDD order, e.g.:- 20100523 20100614 20100721 20100722 20100809 20100901 20101001 20101003 20101104 20101119 20101203 20101218 20110102 I'm looking for a script to import each of these snapshots into GIT. The end result being that the latest code is the same as the last snapshot, and other editions are accessible and are as numbered. Some other requirements: that the latest edition is not cumulative of the previous snapshots, i.e., files that appeared in older snapshots but which don't appear in later ones (e.g. due to refactoring etc.) should not appear in the latest edition of the code. meanwhile, there should be continuity between files that do persist between snapshots. I would like GIT to know that there are previous editions of these files and not treat them as brand new files within each edition. Some background about my aim: I need to formally revision control this work rather than keep local private snapshot copies. I plan to release this work as open source, so version controlling would be highly recommended I am evaluating some of the current popular version control systems (Subversion and GIT) BUT I definitely need a working solution in GIT as well as subversion. I'm not looking to be persuaded to use one particular tool, I need a solution for each tool I am considering. (I haved posted an answer separately for each tool so separate camps of folks who have expertise in GIT and Subversion will be able to give focused answers on one or the other). The same but separate question for Subversion: Script/tool to import series of snapshots, each being a new revision, into Subversion, populating source tree?

• How to capture a Header or Trailer Count Value in a Flat File and Assign to a Variable

  - by Compudicted

  Recently I had several questions concerning how to process files that carry a header and trailer in them. Typically those files are a product of data extract from non Microsoft products e.g. Oracle database encompassing various tables data where every row starts with an identifier. For example such a file data record could look like: HDR,INTF_01,OUT,TEST,3/9/2011 11:23 B1,121156789,DATA TEST DATA,2011-03-09 10:00:00,Y,TEST 18 10:00:44,2011-07-18 10:00:44,Y B2,TEST DATA,2011-03-18 10:00:44,Y B3,LEG 1 TEST DATA,TRAN TEST,N B4,LEG 2 TEST DATA,TRAN TEST,Y FTR,4,TEST END,3/9/2011 11:27 A developer is normally able to break the records using a Conditional Split Transformation component by employing an expression similar to Output1 -- SUBSTRING(Output1,1,2) == "B1" and so on, but often a verification is required after this step to check if the number of data records read corresponds to the number specified in the trailer record of the file. This portion sometimes stumbles some people so I decided to share what I came up with. As an aside, I want to mention that the approach I use is slightly more portable than some others I saw because I use a separate DFT that can be copied and pasted into a new SSIS package designer surface or re-used within the same package again and it can survive several trailer/footer records (!). See how a ready DFT can look: The first step is to create a Flat File Connection Manager and make sure you get the row split into columns like this: After you are done with the Flat File connection, move onto adding an aggregate which is in use to simply assign a value to a variable (here the aggregate is used to handle the possibility of multiple footers/headers): The next step is adding a Script Transformation as destination that requires very little coding. First, some variable setup: and finally the code: As you can see it is important to place your code into the appropriate routine in the script, otherwise the end result may not be as expected. As the last step you would use the regular Script Component to compare the variable value obtained from the DFT above to a package variable value obtained say via a Row Count component to determine if the file being processed has the right number of rows.

• Geekswithblogs.net Influencer Programm

  - by Staff of Geeks

  Recently, @StaffOfGeeks announced to a select group of bloggers, the Geekswithblogs.net Influencer Program.  Here is a little detail about the program. Description (from Influencer Page): Geekswithblogs.net is a community of bloggers passionate about contributing information to the world of developers and IT professionals. Our bloggers are some of the best in the world and receive honors on a regular basis for outside companies (such as the Microsoft© MVP Program). The Geekswithblogs.net Influencer Program is our way as Staff of Geeks to show our appreciation for those bloggers who have the greatest influence on the site. Each influencer in the program is awarded by the amount of posts, views, and comments they receive on their posts in the previous quarter. Each quarter, we select the top 25 bloggers of influence and give them special access to products and services we have obtained through our network of partners. Here is how it works.  Each quarter we select the top 25 bloggers bases on the amount of posts that created in that quarter, and apply points to the views and comments those posts receive.  The selection is purely off of the numbers, we do not select any based on any other basis.  In fact in the first round, several of our key bloggers did not qualify in the top 25.  Though they are still loved dearly, we wanted a program that anyone could be a part of if they put in the hard work. This said, the first quarter ends at the end of March and we will have another round of influencers joining us.  Keep the posts rolling and maybe you will be selected as an influencer! Visit the influencers page to see who has the greatest influence on Geekswithblogs right now.   Technorati Tags: Geekswithblogs

• Java Management Extensions with Oracle WebLogic Server 12c–Webcast Nocember 13th 2012

  - by JuergenKress

  Date: Tuesday, November 13, 2012 Time: 10:00 AM PST You’re responsible for evaluating technologies to monitor and configure Oracle WebLogic Server. This Webcast will help you get a complete picture of what Oracle WebLogic Server 12c with Java Management Extensions (JMX) can do for you. Dr. Frank Munz will explain the development of JMX with Spring and compare it to Java EE. A new feature of Oracle WebLogic Server 12c, the RESTful Management API, will also be examined. Learn how JMX in Oracle WebLogic Server 12c is: Highly efficient. It uses WebLogic Scripting Tool (WLST) instead of a client JMX program written in Java, resulting in little overhead. Effective. It bundles optimized tools such as WLST and WebLogic Diagnostic Framework to eliminate the requirement for Java programming on the client side. Compliant. It is fully standard-compliant but also works with open source clients and frameworks. Register for the Webcast today. Speakers: Dr. Frank Munz, Oracle Technologist of the Year Dave Cabelus, Senior Principal Product Manager, Oracle WebLogic Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).
