  • Wiki based requirements engineering tool

    - by Shanon
    Hi, I'm looking to to build a wiki based tool the helps/aides in the requirements engineering process. More specifically I am hoping to end up with a tool that helps inexperienced users easily create and design requirements documents on a wiki platform. I was wondering if there exist any wiki/wiki platforms that either already exist or are easily extendible or would be worth looking at that for this purpose. For instance some of the features I was hoping to add would be to add structure to a document so that information is filled out in a standardised manner. Another idea I was looking at was to somehow create relationships between different types of documents (for example- a goal diagram gets evolves/ helps in the development of the class diagram). So far I have come across FOSwiki which claims to to fully customisalble...but I'm not sure what it means and what I can really do with that. Any input on FOSwiki is also highly appreciated.

  • Managing software projects - advice needed

    - by Callum
    I work for a large government department as part of an IT team that manages and develops websites as well as stand alone web applications. We’re running in to problems somewhere in the SDLC that don’t rear their ugly head until time and budget are starting to run out. We try to be “Agile” (software specifications are not as thorough as possible, clients have direct access to the developers any time they want) and we are also in a reasonably peculiar position in that we are not allowed to make profit from the services we provide. We only service the divisions within our government department, and can only charge for the time and effort we actually put in to a project. So if we deliver a project that we have over-quoted on, we will only invoice for the actual time spent. Our software specifications are not as thorough as they could be, but they always include at a minimum: Wireframe mockups for every form view A data dictionary of all field inputs Descriptions of any business rules that affect the system Descriptions of the outputs I’m new to software management, but I’ve overseen enough software projects now to know that as soon as users start observing demos of the system, they start making a huge amount of requests like “Can we add a few more fields to this report.. can we redesign the look of this interface.. can we send an email at this part of the workflow.. can we take this button off this view.. can we make this function redirect to a different screen.. can we change some text on this screen… can we create a special account where someone can log in and get access to X… this report takes too long to run can it be optimised.. can we remove this step in the workflow… there’s got to be a better image we can put here…” etc etc etc. Some changes are tiny and can be implemented reasonably quickly.. but there could be up to 50-100 or so of such requests during the course of the SDLC. Other change requests are what clients claim they “just assumed would be part of the system” even if not explicitly spelled out in the spec. We are having a lot of difficulty managing this process. With no experienced software project managers in our team, we need to come up with a better way to both internally identify whether work being requested is “out of spec”, and be able to communicate this to a client in such a manner that they can understand why what they are asking for is “extra” work. We need a way to track this work and be transparent with it. In the spirit of Agile development where we are not spec'ing software systems in to the ground and back again before development begins, and bearing in mind that clients have access to any developer any time they want it, I am looking for some tips and pointers from experienced software project managers on how to handle this sort of "scope creep" problem, in tracking it, being transparent with it, and communicating it to clients such that they understand it. Happy to clarify anything as needed. I really appreciate anyone who takes the time to offer some advice. Thanks.

  • Keyword Generator Tool Gets Your Ahead of the Competition

    A keyword generator tool provides ideas that website owners and search engine optimizers use for site and engine optimization. Key phrase generators rely on search query popularity from introductory keywords to a more complex keyword search management to drive more traffic to a website. It maximizes prospective and potential high-traffic keywords and integrates it with your sites campaign techniques. Keyword generator tool allows you to manage and add "exact match" and "phrase match" keywords to your lists, also allows you to create misspellings, combine and reverse keywords then automatically calculates the ad group focus score of your keyword lists.

  • Dependency Management tool for REST endpoints

    - by ShaggyInjun
    I work in a Rest Oriented envrionment. The number of endpoints is quite large and span multiple applications. The dependencies between the endpoints are large in number as well and not very well planned. Applications have cyclic dependencies amongst each other. Unfortunately, there is no central location where all the endpoints are documented and declare dependencies ( the endpoints that they inturn call ). Is there a tool that will help in such dependency management. I tried searching for a tool online, but not know what such a thing would be called, I am unable to find anything. P.S. Google only helps those who know what they need help with. :(

  • ACL tool for audit of Ubuntu production servers

    - by migrator
    In my production environment, I have close to 10 Ubuntu 12.04 Servers and I want to get the list of users from them. I am looking for some kind of script or tool (non-gui) to get the same. Yes, I can get the list from /etc/passwd and /etc/groups files but it would be good to have a tool or script to do this due to the following reasons. I have right now 10 systems in Ubuntu and 30 systems in Windows 2003. I am recommending my organization and IT to move all the systems to Ubuntu except the one running MS SQL server We do not have good Ubuntu admins with us and they should not mess up with the system if I give some manual commands I also need to find out date of creation of user, group, password standards like strength, expiry etc Please help me as I want to automate the process and get the list on weekly basis from IT team. Thanks in advance.

  • Advice on learning programming languages and math.

    - by Joris Ooms
    I feel like I'm getting stuck lately when it comes to learning about programming-related things; I thought I'd ask a question here and write it all down in the hope to get some pointers/advice from people. Perhaps writing it down helps me put things in perspective for myself aswell. I study Interactive Multimedia Design. This course is based on two things: graphic design on one hand, and web development on the other hand. I have quite a decent knowledge of web-related languages (the usual HTML/JS/PHP) and I'll be getting a course on ASP.NET next year. In my free time, I have learnt how to work with CodeIgniter, aswell as some diving into Ruby (and Rails) and basic iOS programming. In my first year of college I also did a class on Java (19/20 on the end result). This grade doesn't really mean anything though; I have the basics of OOP down but Java-wise, we learnt next to nothing. Considering the time I have been programming in, for example, PHP.. I can't say I'm bad at it. I'm definitely not good or great at it, but I'm decent. My teachers tell me I have the programming thing down. They just tell me I should keep on learning. So that's what I do, and I try to take in as much as possible; however, sometimes I'm unsure where to start and I have this tendency to always doubt myself. Now, for the 'question'. I want to get into iOS programming. I know iOS programming boils down to programming in Cocoa Touch and Objective-C. I also know Obj-C is a superset of C. I have done a class on C a couple of years ago, but I failed miserably. I got stuck at pointers and never really understood them.. Until like a month ago. I suddenly 'got' it. I have been working through a book on Objective-C for a week or so now, and I understand the basics (I'm at like.. chapter 6 or so). However, I keep running into similar problems as the ones I had when I did the C class: I suck at math. No, really. I come from a Latin-Modern Languages background in high school and I had nearly no math classes back then. I wanted to study Computer Science, but I failed there because of the miserable state of my mathematics knowledge. I can't explain why I'm suddenly talking about math here though, because it isn't directly related to programming.. yet it is. For example, the examples in the book I'm reading now are about programming a fraction-calculator. All good, I can do the programming when I get the formulas down.. but it takes me a full day or more to actually get to that point. I also find it hard to come up with ideas for myself. I made one small iOS app the other day and it's just a button / label kind of thing. When I press the button, it generates a random number. That's really all I could come up with. Can you 'learn' that? It probably comes down to creativity, but evidently, I'm not too great at being creative. Are there any sites or resources out there that provide something like a basic list of things you can program when you're just starting out? Maybe I'm focusing on too many things at once. I want to keep my HTML/CSS at a decent level, while learning PHP and CodeIgniter, while diving into Ruby on Rails and learning Objective-C and the iOS SDK at the same time. I just want to be good at something, I guess. The problem is that I can't seem to be happy with my PHP stuff. I want more, something 'harder'; that's why I decided to pick up the iOS thing. Like I said, I have the basics down of a lot of different languages. I can program something simple in Java, in C, in Objective-C as of this week.. but it ends there. Mostly because I can't come up with ideas for more complex applications, and also because I just doubt myself: 'Oh, that's too complex, I can never do that'. And then it ends there. To conclude my rant, let me basically rephrase my questions into a 'tl;dr' part. A. I want to get into iOS programming and I have basic knowledge of C/Objective-C. However, I struggle to come up with ideas of my own and implement them and I also suck at math which is something that isn't directly related to, yet often needed while programming. What can I do? B. I have an interest in a lot of different programming languages and I can't stop reading/learning. However, I don't feel like I'm good in anything. Should I perhaps focus on just one language for a year or longer, or keep taking it all in at the same time and hope I'll finally get them all down? C. Are there any resources out there that provide basic ideas of things I can program? I'm thinking about 'simple' command-line applications here to help me while studying C/Obj-C away from the whole iPhone SDK. Like I said, the examples in my book are mainly math-based (fraction calculator) and it's kinda hard. :( Thanks a lot for reading my post. I didn't plan it to be this long but oh well. Thanks in advance for any answers.

  • Intellectual Property for in house development

    - by Kyle Rogers
    My company is a sub contractor on a major government contract. Over the past 5 years we've been developing in house applications to help support our company and streamline our work. Apparently in 2008 our president of the company at that time signed a continuation of services contract with the company we subcontract with on this project. In the contract amendment various things were discussed such as intellectual property and the creation of new and existing tools. The contract states that all the subcontractor's tools/scripts/etc... become the intellectual property of the main contractor holder. Basically all tools that were created in support of the project which we work on are no longer ours exclusively and they have rights to them. My company really doesn't do software development specifically but because of this contract these tools helped tremendously with our daily tasking. Does my company have any sort of recourse or actions to help keep our tools? My team of developers were completely unaware of any of these negotiations and until recently were kept in the dark about the agreements that were made. Do we as developers have any rights to the software? Since our company is not a software development shop, we have created all these tools without any sort of agreements or contracts within the company stating that we give our company full rights to our creations? I was reading an article by Joel Spolsky on this topic and was just wonder if there is any advice out there to help assist us? Thank you Joel Spolsky's Article

  • What should I quote for a project I hope to get a job at the end of?

    - by thesunneversets
    Long story short: I applied for a (CakePHP, MySQL, etc) development job in London, UK. I grew up in Britain but am currently based quite a few thousand miles away in Canada, so I wasn't really expecting success. But quite a few emails and phone interviews later it seems that they really like me. At least to a point. Because such a major relocation would be a horrible thing to go wrong, they've sensibly suggested a trial run of getting me to build a website at a distance. I have the spec for this and it's quite a substantial amount of work. My problem is that I now need to suggest both a fee and a timescale for the job, and I haven't got any significant experience of working as a contractor. Looking at the spec, which is 1500 words of many concisely stated features, some fairly trivial and some moderately involved, I can easily imagine there being 2 weeks of intensive work there. (If everything went really well it might be closer to one week, but even though I want to impress, I definitely don't want to fall into the inexperienced-contractor trap of massively underestimating the amount of time a project will run to.) As an extra complication, there is no expectation that I should give up my day job to get this trial project done, so the hours will have to be clawed from evenings and weekends. I don't want to overcommit to a quick delivery date, only to find myself swiftly burning out due to an unrealistic workload. So, any advice for me? My main question is, what is a realistic hourly figure to demand of a stable but not excessively wealthy London-based company in the current market, bearing in mind that I'd like them to hire me afterwards? But any more general recommendations based on my circumstances above would be much appreciated too. Many thanks!

  • How do I get others to see past my prior inexperience?

    - by Kevin
    My core question is how do I proceed from the following predicament. I will be honest with you, I wasted my College Experience. I slacked off and didn't take any of my comp sci classes that seriously, somehow i still got out with a 3.25 GPA. But truth be told I learned nothing. I befriended most of my professors who went pretty lenient on me in terms of grading. However, I basically came out of College knowing how to program a simple calculator in VB.Net. I was (to my great surprise) hired by a very large respected company in Denver as a Junior developer. Well the long and the short of it is that I knew so little about programming that I quickly became the office pariah and was almost fired due to my incompetence. It has been 8 months now and I feel I have learned some basic things and I am not as picked on as I used to be by the other developers. However, everyone hates me and the first few months have given the other developers a horrible perception of me. I am no longer afraid of code or learning, but I have put my self in the precarious position of being the scapegoat of our department. I hate going to work every day because no one there is my friend and pretty much everyone is hostile to me. What should I do? Any advice?

  • Is learning how to use C (or C++) a requirement in order to be a good (excellent) programmer?

    - by blueberryfields
    When I first started to learn how to program, real programmers could write assembly in their sleep. Any serious schooling in computer science would include a hefty bit of training and practice in programming using assembly. That has since changed, to the point where I see Computer Science degrees with assembly, if included at all, is relegated to one assignment, and one chapter, for a total of two weeks' work out of 4 years' schooling. C/C++ programming seems to have followed a similar path. I'm no longer surprised to interview university graduates who have not spent more than two weeks programming in C++, and have only read of C in a book somewhere. While the most serious CS degrees still seem to include significant time learning and using one or both of the languages, the trend is clearly towards less enforced C/C++ in school. It's clearly possible to make a career producing good work without ever reading or writing a single line of C or C++ code. Given all of that, is learning the two languages worth the effort? Are they at all required to excel? (beyond the obvious, non-language specific advice, such as "a good selection of languages is probably important for a comprehensive education", and "it's probably a good idea to keep trying out and learning new languages throughout a programmers' career, just to stretch the gray cells")

  • So my employer wants me to do less programming and focus on IT support

    - by Rich
    I was hired into a non tech company's IT department as a programmer a few years back, and after several rounds of lay offs, we're down to a skeleton crew. I've saved the company hundreds of thousands of dollars with my projects and management has been happy with them (although most of the stakeholders have since left the company). Management now wants me to limit the programming that I do and spend most of my time on IT support: putting out fires, dealing with vendors, outsourced contractors, supporting company systems, managing projects, etc. I am a little burnt out on programming since I've been pushed pretty hard for the past several years. However, I'm not sure if this is a good career move in the long run. I'm a decent programmer (and also good with databases) but not obsessed with it to the point of coding outside of work. I'm approaching my mid 30s and there's potential ageism to deal with down the line. While I'm fortunate to have survived the lay offs, it sorta feels like my job is being "dumbed down". I have both good technical skills and people skills...but it doesn't take a genius to do what I'm doing now. And my success is being increasingly linked to others' performance rather than my own... Just looking for some advice. Is it time to move on? That's not really an easy thing to do since I'd likely have to move to another area to find another comparable tech job. Should I go after another pure technical role? Or should I stay and try to make this work? People say do what you "enjoy" but it doesn't really matter to me as long as I'm getting paid. Also the ageism thing is on the horizon and could be an issue eventually. I'm making a decent (but not great) salary. Should I chase money and maximize my income while I still have a chance? Or be happy with a moderate salary and 40 hour work week?

  • SQL SERVER – 3 Challenges for DBA and Smart Solutions

    - by Pinal Dave
    Developer’s life is never easy. DBA’s life is even crazier. DBA’s Life When a developer wakes up in the morning, most of the time have no idea what different challenges they are going to face that day. Of course, most of the developers know the project and roadmap, which they are working on. However, developers have no clue what coding challenges which they are going face for that day. DBA’s life is even crazier. When DBA wakes up in the morning – they often thank that they were not disturbed during the night due to server issues. The very next thing they wish is that they do not want to challenge which they can’t solve for that day. The problems DBA face every single day are mostly unpredictable and they just have to solve them as they come during the day. Though the life of DBA is not always bad. There are always ways and methods how one can overcome various challenges. Let us see three of the challenges and how a DBA can use various tools to overcome them. Challenge #1 Synchronize Data Across Server A Very common challenge DBA receive is that they have to synchronize the data across the servers. If you try to manually write that up, it may take forever to accomplish the task. It is nearly impossible to do the same with the help of the T-SQL. However, thankfully there are tools like dbForge Studio which can save a day and synchronize data across servers. Read my detailed blog post about the same over here: SQL SERVER – Synchronize Data Exclusively with T-SQL. Challenge #2 SQL Report Builder DBA’s are often asked to build reports on the go. It really annoys DBA’s, but hardly people care about it. No matter how busy a DBA is, they are just called upon to build reports on things on very short notice. I personally like to avoid any task which is given to me accidently and personally building report can be boring. I rather spend time with High Availability, disaster recovery, performance tuning rather than building report. I use SQL third party tool when I have to work with SQL Report. Others have extended reporting capabilities. The latter group of products includes the SQL report builder built-in todbForge Studio for SQL Server. I have blogged about this earlier over here: SQL SERVER – SQL Report Builder in dbForge Studio for SQL Server. Challenge #3 Work with the OTHER Database The manager does not understand that MySQL is different from SQL Server and SQL Server is different from Oracle. For them everything is same. In my career hundreds of times I have faced a situation that I am given a database to manage or do some task when their regular DBA is on vacation or leave. When I try to explain I do not understand the underlying the technology, I have been usually told that my manager has trust on me and I can do anything. Honestly, I can’t but I hardly dare to argue. I fall back on the third party tool to manage database when it is not in my comfort zone. For example, I was once given MySQL performance tuning task (at that time I did not know MySQL so well). To simplify search for a problem query let us use MySQL Profiler in dbForge Studio for MySQL. It provides such commands as a Query Profiling Mode and Generate Execution Plan. Here is the blog post discussing about the same: MySQL – Profiler : A Simple and Convenient Tool for Profiling SQL Queries. Well, that’s it! There were many different such occasions when I have been saved by the tool. May be some other day I will write part 2 of this blog post.

  • Studentworker - being a superhero?

    - by Niklas H
    A couple of weeks ago I got a new job as a studentworker for a webagency. The job is 15-20 hours of week. Even though I am new in the company, I feel right at home and I enjoy working with my co-workers. To start of with, I was assigned to work on an internal tool in the company, in order to learn their systems and their development platform. The deadline for this project is this week, and I am right on time. But today (wednesday at noon) I received an email from my boss, asking me to do a new project that has a deadline at friday morning. The new assignment alone will be hard to finish on time, and on top of that I need to finish the other assignment on time. My question is: How do I handle my boss expecting me to be a superhero? EDIT: I will talk to my boss about delaying one of the projects. But another problem is that the new assignment will be hard to do on time (friday morning). I didn't have a say on the deadline - I just got a mail telling me the deadline. I am new in the company and want to stay, but I don't want to start off on the wrong foot with the boss.

  • What to do if I am working on a language that I don't like

    - by Sayem Ahmed
    Hi there, I really don't know if this is the right place to ask this question, but if it isn't, then I guess someone will notify. Anyway, I am working in a software development farm which is currently using PowerBuilder to develop a mid-size ERP solution. The work environment and company management are so great that it may be the best in the whole Bangladesh. Only problem is the technology that are currently being used, which is this PowerBuilder. Now I am a guy who tends to prefer modern development technologies, like DI containers, ORM, TDD, JQuery etc. PowerBuilder is a great tool too, but I couldn' like the application techniques used to build PB applications. These techniques are so inheritance-dependent that many a times these create a great deal of sufferings. I remember two days ago I had to change some processing logic in a core user object and as a result I had to test and re-test all the forms that the application have(apparently, there are almost 20 forms there, each of them with 3-4 kinds of functionalities). Also, learning PB is tough, because online material on this thing is very, very low. I can't afford to read all the documentation that PB provide because I have hard deadlines on the work that I have to do. Another thing with PB is that applications tend to rely on business logic that are implemented on databases which causes debugging to be a nightmare. As a result, I don't feel motivated enough to work in this IDE/System/Framework (or whatever) anymore. My productivity has greatly decreased, and I am not delivering quality code. I think I have the following options available to me - Remain in the current job, keep delivering worse code and let my productivity decrease day by day, taking salaries and bonuses but not delivering quality codes/doing my job the way I should, Search for a new job. At this point number 2 seems a good option, but there are also some issues. As I mentioned before, our management may be the best in the country. Our company owner is himself a software developer with 24 years of experience in software development. He is currently our Team Leader and System Analyst. He is by far the greatest manager and boss I have ever seen. He understands developer's mentality very well(as he IS himself a developer). He is also a great, kind and generous guy. Our company is only a start-up company with 10 developers. Among them, only 3-4 people knows about the business logic behind the ERP, and I am one of them. If I switch my current job, it may hamper the development of this product which I really don't want. I couldn't decide what to do in this situation, so I turned to the community for advice.

  • Networking Guidelines

    - by ACShorten
    One of the things I have noticed in my years in IT is the changes in networking. In the past networking was pretty simple with the host name and name resolution (via DNS) being pretty simple. Some sites still use this simple networking setup. These days, more complex name resolution, proxies, firewalls, demarcation nd virtualization, can make networking more complex. This can cause issues when installing products with in built networking that can frustrate even seasoned veterans. I have put together a few basic guidelines to hopefully help along with product installation and getting a product to operate in a somewhat complex network setup. All the components of the product (including the infrastructure) need to communicate via a network (even it is within a local machine/host). Ensure any host names referred to within configuration files are accessible via your networking setup. This may mean defining the hosts to the machines, to the DNS for name resolution and even your firewall to allow machines to communicate within your network. Make sure the ports used for any of the infrastructure are accessible (even through your firewall) and are unique within the host. Host duplication can cause the product to fail on startup as the port is already in use. If there are still issues, consider using localhost as your host name. I have used this in so many situations that I tend to use it now as a default anytime I install anything myself. Most Oracle products suggest to use localhost when using dynamic host or dynamic IP addresses and this is no different for the Oracle Utilities Application Framework. If you do use localhost then installing a Loopback Adapter for the operating system is recommended to force networking to a minimum. Usually localhost resolves to 127.0.0.1. When using multiple network connections, especially in a virtualized environment, ensure the host and ports used are relevent for the network cards you have setup. One of the common issues is finding the product is using a vierualized network card only to find that it is not setup for correct networking. If you are using the batch component, do not forget to ensure that the multicast protocol is enabled on your host and that the multicast address and port number specified are valid and accessible from all machines in the batch cluster (if clustering used). The same advice applies if you are using unicast where each host/port combination should be accessible. Hopefully these basic networking recommendations will help minimize any networking issues you might encounter.

  • IntelliTrace As a Learning Tool for MVC2 in a VS2010 Project

    - by Sam Abraham
    IntelliTrace is a new feature in Visual Studio 2010 Ultimate Edition. I see this valuable tool as a “Program Execution Recorder” that captures information about events and calls taking place as soon as we hit the VS2010 play (Start Debugging) button or the F5 key. Many online resources already discuss IntelliTrace and the benefit it brings to both developers and testers alike so I see no value of just repeating this information.  In this brief blog entry, I would like to share with you how I will be using IntelliTrace in my upcoming talk at the Ft Lauderdale ArcSig .Net User Group Meeting on April 20th 2010 (check http://www.fladotnet.com for more information), as a learning tool to demonstrate the internals of the lifecycle of an MVC2 application.  I will also be providing some helpful links that cover IntelliTrace in more detail at the end of my article for reference. IntelliTrace is setup by default to only capture execution events. Microsoft did such a great job on optimizing its recording process that I haven’t even felt the slightest performance hit with IntelliTrace running as I was debugging my solutions and projects.  For my purposes here however, I needed to capture more information beyond execution events, so I turned on the option for capturing calls in addition to events as shown in Figures 1 and 2. Changing capture options will require us to stop our debugging session and start over for the new settings to take place. Figure 1 – Access IntelliTrace options via the Tools->Options menu items Figure 2 – Change IntelliTrace Options to capture call information as well as events Notice the warning with regards to potentially degrading performance when selecting to capture call information in addition to the default events-only setting. I have found this warning to be sure true. My subsequent tests showed slowness in page load times compared to rendering those same exact pages with the “event-only” option selected. Execution recording is auto-started along with the new debugging session of our project. At this point, we can simply interact with the application and continue executing normally until we decide to “playback” the code we have executed so far.  For code replay, first step is to “break” the current execution as show in Figure 3.   Figure 3 – Break to replay recording A few tries later, I found a good process to quickly find and demonstrate the MVC2 page lifecycle. First-off, we start with the event view as shown in Figure 4 until we find an interesting event that needs further studying.  Figure 4 – Going through IntelliTrace’s events and picking as specific entry of interest We now can, for instance, study how the highlighted HTTP GET request is being handled, by clicking on the “Calls View” for that particular event. Notice that IntelliTrace shows us all calls that took place in servicing that GET request. Double clicking on any call takes us to a more granular view of the call stack within that clicked call, up until getting to a specific line of code where we can do a line-by-line replay of the execution from that point onwards using F10 or F11 just like our typical good old VS2008 debugging helped us accomplish. Figure 5 – switching to call view on an event of interest Figure 6 – Double clicking on call shows a more granular view of the call stack. In conclusion, the introduction of IntelliTrace as a new addition to the VS developers’ tool arsenal enhances development and debugging experience and effectively tackles the “no-repro” problem. It will also hopefully enhance my audience’s experience listening to me speaking about  an MVC2 page lifecycle which I can now easily visually demonstrate, thereby improving the probability of keeping everybody awake a little longer.

  • JMX Based Monitoring - Part Two - JVM Monitoring

    - by Anthony Shorten
    This the second article in the series focussing on the JMX based monitoring capabilities possible with the Oracle Utilities Application Framework. In all versions of the Oracle utilities Application Framework, it is possible to use the basic JMX based monitoring available with the Java Virtual Machine to provide basic statistics ablut the JVM. In Java 5 and above, the JVM automatically allowed local monitoring of the JVM statistics from an approporiate console. When I say local I mean the monitoring tool must be executed from the same machine (and in some cases the same user that is running the JVM) to connect to the JVM directly. If you are using jconsole, for example, then you must have access to a GUI (X-Windows or Windows) to display the jconsole output. This is the easist way of monitoring without doing too much configration but is not always practical. Java offers a remote monitorig capability to allow yo to connect to a remotely executing JVM from a console (like jconsole). To use this facility additional JVM options must be added to the command line that started the JVM. Details of the additional options for the version of the Java you are running is located at the JMX information site. Typically to remotely connect to a running JVM that JVM must be configured with the following categories of options: JMX Port - The JVM must allow connections on a listening port specified on the command line Connection security - The connection to the JVM can be secured. This is recommended as JMX is not just a monitoring protocol it is a managemet protocol. It is possible to change values in a running JVM using JMX and there are NO "Are you sure?" safeguards. For a Oracle Utilities Application Framework based application there are a few guidelines when configuring and using this JMX based remote monitoring of the JVM's: Online JVM - The JVM used to run the online system is embedded within the J2EE Web Application Server. To enable JMX monitoring on this JVM you can either change the startup script that starts the Web Application Server or check whether your J2EE Web Application natively supports JVM statistics collection. Child JVM's (COBOL only) - The Child JVM's should not be monitored using this method as they are recycled regularly by the configuration and therefore statistics collected are of little value. Batch Threadpoools - Batch already has a JMX interface (which will be covered in another article). Additional monitoring can be enabled but the base supported monitoring is sufficient for most needs. If you are an Oracle Utilities Application Framework site, then you can specify the additional options for JMX Java monitoring on the OPTS paramaters supported for each component of the architecture. Just ensure the port numbers used are unique for each JVM running on any machine.
