  Barry N. Perkins: Unique Business Value vs. Unique IT "Some solutions may look good today, solving a budget challenge by reducing cost, or solving a specific tactical challenge, but result in highly complex environments, that may be difficult to manage and maintain and limit the future potential of your business.

• Should I be put off a junior role that uses an online development test?

  - by Ninefingers

  I've applied for a junior development role, or rather been found by a recruiter looking for a developer. In order to get to a telephone interview stage I've been asked to sit one of those online coding assessments. This wasn't quite what I expected. I consider myself a fairly good developer for my age and experience, but I've no illusions about being Don Knuth or anything. The test was a series of incredibly obtuse questions asking about the results of various obscure evaluations. About 30 minutes in I was thinking to myself I hadn't intended to enter an obfuscated code contest/code golf exercise. After my last telephone interview I was asked to build something. I did. That seemed fair. Go away and work this out is more my in office experience of programming than "please evaluate this combination of lambdas, filters, maps, lists, tuples etc". So I'm a little put off, to be honest. I never claimed to know the language inside out or all the little corner cases. My questions, then: Should I be put off? Why? Why not? Are these kinds of tests what I should be expecting for junior roles? Should I learn stuff exam style? That seems to be the objective of these tests, for which you are timed and not supposed to use references or books? Normally, in the course of development I have a fairly good idea of basic types, rules, flow control and whatever. Occasionally I'll come up on something I need to use a regex for and have to go and remind myself of the exact piece of syntax I need if trying what I think should work doesn't. Or I'll come up against a module I've not used before and go and look it up. For example, if I wanted to write a server using sockets in C right now, I'd probably check the last piece of code I wrote doing that (and or the various books I have) and work from there. Chances are I probably couldn't do it exactly from scratch and from memory, although I can tell you you'd need a socket(), bind(), listen() and accept() call and you might also want select() depending on whether you intend to pthread_create or not. So I know what the calls are, but not their specific parameter list. What are your experiences if you are a recruiting manager? Are you after programmers who can quote you the API or do you not mind if your programmers have a few books on their desk and google function calls every so often?

• Safely deploying changes to production servers

  - by oazabir

  When you deploy incremental changes on a production server, which is running and live all the time, you some times see error messages like “Compiler Error Message: The Type ‘XXX’ exists in both…”. Sometimes you find Application_Start event not firing although you shipped a new class, dll or web.config. Sometimes you find static variables not getting initialized and so on. There are so many weird things happen on webservers when you incrementally deploy changes to the server and the server has been up and running for several weeks. So, I came up with a full proof house keeping steps that we always do whenever we deploy some incremental change to our websites. These steps ensure that the web sites are properly recycled , cached are cleared, all the data stored at Application level is initialized. First of all you should have multiple web servers behind load balancer. This way you can take one server our of the production traffic, do your deployment and house keeping tasks like restarting IIS, and then put it back. Then you can do it for the second server and so on. This ensures there’s no outage for customer. If you can do it reasonable fast, hopefully customers won’t notice discrepancy between the servers some having new code and some having old code. You should only do this when your changes aren’t drastic. For ex, you aren’t delivering a complete revamped UI. In that case, some users hitting server1 with latest UI will suddenly get a completely different experience and then on next page refresh, they might hit server2 with old code and get a totally different experience. This works for incremental non-dramatic changes only.   During deployment you should follow these steps: Take server X out of load balancer so that it does not get any traffic. Stop all windows services on the server. Stop IIS. Delete the Temporary ASP.NET folders of all .NET versions incase you have multiple .NET versions running. You can follow this link. Deploy the changes. Flush any distributed cache you have, for ex, Velocity or Memcached. Start IIS. Start the windows services on the server. Warm up all websites by hitting major URLs on the websites. You should have some automated script to do this. You can use tinyget to hit some major URLs, especially pages that take a lot of time to compile. Read my post on keeping websites warm with zero coding. Put server X back to load balancer so that it starts receiving traffic. That’s it. It should give you a clean deployment and prevent unexpected errors. You should print these steps and hang on the desk of your deployment guys so that they never forget during deployment pressure.

• Securing User Account Details with MySQL

  - by Antoinette O'Sullivan

  Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures. You can learn more about this and many other topics in the MySQL for Database Administrator course. For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security. The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and invisible to everyone else. You can use it to collect all your hard-to-remember server locations and paswords safe in the knowledge that your passwords are never invoked using clear text. The MySQL for Database Administrators course is a 5-day instructor-led course which is available as a: Training-on-Demand: Start training within 24 hours of registration, following lecture material at your own pace through streaming video and booking time on a lab environment to suit your schedule.

• Viewing at Impossible Angles

  - by kemer

  The picture of the little screwdriver with the Allen wrench head to the right is bound to invoke a little nostalgia for those readers who were Sun customers in the late 80s. This tool was a very popular give-away: it was essential for installing and removing Multibus (you youngsters will have to look that up on Wikipedia…) cards in our systems. Back then our mid-sized systems were gargantuan: it was routine for us to schlep around a 200 lb. desk side box and 90 lb. monitor to demo a piece of software your smart phone will run better today. We were very close to the hardware, and the first thing a new field sales systems engineer had to learn was how put together a system. If you were lucky, a grizzled service engineer might run you through the process once, then threaten your health and existence should you ever screw it up so that he had to fix it. Nowadays we make it much easier to learn the ins and outs of our hardware with simulations–3D animations–that take you through the process of putting together or replacing pieces of a system. Most recently, we have posted three sophisticated PDFs that take advantage of Acrobat 9 features to provide a really intelligent approach to documenting hardware installation and repair: Sun Fire X4800/X4800 M2 Animations for Chassis Components Sun Fire X4800/X4800 M2 Animations for Sub Assembly Module (SAM) Sun Fire X4800/X4800 M2 Animations for CMOD Download one of these documents and take a close look at it. You can view the hardware from any angle, including impossible ones. Each document has a number of procedures, that break down into steps. Click on a procedure, then a step and you will see it animated in the drawing. Of course hardware design has generally eliminated the need for things like our old giveaway tools: components snap and lock in. Often you can replace redundant units while the system is hot, but for heaven’s sake, you’ll want to verify that you can do that before you try it! Meanwhile, we can all look forward to a growing portfolio of these intelligent documents. We would love to hear what you think about them. –Kemer

• Sometimes keyboard & touchpad work... sometimes not

  - by Voyagerfan5761

  When I first ran Ubuntu from CD on this Dell Inspiron 2650, it worked for about ten to fifteen minutes, then it hung (I was probably trying to do too much at once from a Live CD). The next time, my mouse and keyboard didn't work. I rebooted three times and finally got them working. I then installed Ubuntu alongside Windows XP. After installing, selecting the OS in GRUB worked, but my touchpad and keyboard were again not working. I rebooted, and they worked. (I fortunately had a USB mouse with which to reboot.) Booting Ubuntu and then rebooting to enable my keyboard and touchpad has become a routine ever since. Often several reboots are required; at one point I had to reboot over a dozen times in a row before getting a session where everything worked properly. (My installation has been in place for about three days a week now.) I've looked around for a device manager equivalent to no avail. Sometimes the hardware is properly detected, and sometimes it's not. Once or twice I've had the keyboard detected properly but the touchpad not. Plugging in my wireless card also sometimes requires a plug, unplug, and plug again to get it working. So is there some solution? I'm without an Internet connection at home, and this "laptop" is really a wall wart on my desk, so suggestions for packages may take a while to test. Xorg logs I captured two three four sample Xorg logs: one from a startup where the devices worked; one from when they didn't; one from a session where Ubuntu thought my touchpad was a normal mouse; and one from a session where my keyboard worked but the touchpad didn't. See this gist. Updated 2010-12-15 01:50 UTC with Xorg.0.log.keyboardonly file illustrating the case where the keyboard worked but not the touchpad. Updated 2011-01-11 04:10 UTC with Xorg.0.log.touchpadregmouse to illustrate a case where the touchpad was detected as a regular mouse (no "Touchpad" tab in mouse prefs).

• Turnkey with LightSwitch

  - by Laila

  Microsoft has long wanted to find a replacement for Microsoft Access. The best attempt yet, which is due out in, or before, September is Visual Studio LightSwitch, with which it is said to be as 'easy as flipping a switch' to use Silverlight to create simple form-driven business applications. It is easy to get confused by the various initiatives from Microsoft. No, this isn't WebMatrix. There is no 'Razor', for this isn't meant for cute little ecommerce sites, but is designed to build simple database-applications of the card-box type. It is more clearly a .NET-based solution to the problem that every business seems to suffer from; the plethora of Access-based, and Excel-based 'private' and departmental database-applications. These are a nightmare for any IT department since they are often 'stealth' applications built by the business in the teeth of opposition from the IT Department zealots. As they are undocumented, it is scarily easy to bring a whole department into disarray by decommissioning a PC tucked under a desk somewhere. With LightSwitch, it is easy to re-write such applications in a standard, maintainable, way, using a SQL Server database, deployed somewhere reasonably safe such as Azure. Even Sharepoint or Windows Communication Foundation can be used as data sources. Oracle's ApEx has taken off remarkably well, and has shaken the perception that, for the business user, Oracle must remain a mystic force accessible only to the priests and acolytes. Microsoft, by comparison had only Access, which was first released in 1992, the year of the Madonna conical bustier. It looks just as dated. Microsoft badly needed an entirely new solution to the same business requirement that led to Access's and Foxpro's long-time popularity, but which had the same allure as ApEx. LightSwitch is sound in its ideas, and comfortingly conventional in its architecture. By giving an easy access to SQL Server databases, and providing a 'thumb and blanket' migration path to Access-heads, LightSwitch seems likely to offer a simple way of pulling more Microsoft users into the .NET community. If Microsoft puts its weight behind it, then it will give some glimmer of hope to the many Silverlight developers that Microsoft is capable of seeing through its .NET revolution.

• As a tooling/automation developer, can I be making better use of OOP?

  - by Tom Pickles

  My time as a developer (~8 yrs) has been spent creating tooling/automation of one sort or another. The tools I develop usually interface with one or more API's. These API's could be win32, WMI, VMWare, a help-desk application, LDAP, you get the picture. The apps I develop could be just to pull back data and store/report. It could be to provision groups of VM's to create live like mock environments, update a trouble ticket etc. I've been developing in .Net and I'm currently reading into design patterns and trying to think about how I can improve my skills to make better use of and increase my understanding of OOP. For example, I've never used an interface of my own making in anger (which is probably not a good thing), because I honestly cannot identify where using one would benefit later on when modifying my code. My classes are usually very specific and I don't create similar classes with similar properties/methods which could use a common interface (like perhaps a car dealership or shop application might). I generally use an n-tier approach to my apps, having a presentation layer, a business logic/manager layer which interfaces with layer(s) that make calls to the API's I'm working with. My business entities are always just method-less container objects, which I populate with data and pass back and forth between my API interfacing layer using static methods to proxy/validate between the front and the back end. My code by nature of my work, has few common components, at least from what I can see. So I'm struggling to see how I can better make use of OOP design and perhaps reusable patterns. Am I right to be concerned that I could be being smarter about how I work, or is what I'm doing now right for my line of work? Or, am I missing something fundamental in OOP? EDIT: Here is some basic code to show how my mgr and api facing layers work. I use static classes as they do not persist any data, only facilitate moving it between layers. public static class MgrClass { public static bool PowerOnVM(string VMName) { // Perform logic to validate or apply biz logic // call APIClass to do the work return APIClass.PowerOnVM(VMName); } } public static class APIClass { public static bool PowerOnVM(string VMName) { // Calls to 3rd party API to power on a virtual machine // returns true or false if was successful for example } }

• OOF checklist

  - by Daniel Moth

  When going on vacation or otherwise being out of office (known as OOF in Microsoft), it is polite and professional that our absence creates the minimum disruption possible to the rest of the business, and especially our colleagues. Below is my OOF checklist - I try to do these as soon as I know I'll be OOF, rather than leave it for the night before. Let the relevant folks on the team know the planned dates of absence and check if anybody was expecting something from you during that timeframe. Reset expectations with them, and as applicable try to find another owner for individual activities that cannot wait. Go through your calendar for the OOF period and decline every meeting occurrence so the owner of the meeting knows that you won't be attending (similar to my post about responding to invites). If it is your meeting cancel it so that people don’t turn up without the meeting organizer being there. Do this even for meetings were the folks should know due to step #1. Over-communicating is a good thing here and keeps calendars all around up to date. Enter your OOF dates in whatever tool your company uses. Typically that is the notification to your manager. In your Outlook calendar, create a local Appointment (don't invite anyone) for the date range (All day event) setting the "Show As" dropdown to "Out of Office". This way, people won’t try to schedule meetings with you on that day. If you use Lync, set the status to "Off Work" for that period. If you won't be responding to email (which when on your vacation you definitely shouldn't) then in Outlook setup "Automatic Replies (Out of Office)" for that period. This way people won’t think you are rude when not replying to their emails. In your OOF message point to an alias (ideally of many people) as a fallback for urgent queries. If you want to proactively notify individuals of your OOFage then schedule and send a multi-day meeting request for the entire period. Remember to set the "Show As" to "Free" (so their calendar doesn’t show busy/oof to others), set the "Reminder" to "None" (so they don’t get a reminder about it), set "Low Importance", and uncheck both "Response Options" so if they don't want this on their calendar, it is just one click for them to get rid of it. Aside: I have another post with advice on sending invites. If you care about people who would not observe the above but could drop by your office, stick a physical OOF note at your office door or chair/monitor or desk. Have I missed any?

• What You Said: Staying Productive While Working from home

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your telecommuting/work-from-home productivity tips. Now we’re back with a tips and tricks roundup; read on to see how your fellow readers stay focused at home. By far and away the most common technique deployed as carefully isolating work from home life. Carol writes: I love working from home and have done so for 6 years now. I have a routine just as if I was going to an office, except my commute is 12 steps. I get ready for work, grab my purse and smart phone and go to up the steps to my office. I maintain a separate phone line and voice mail for work that I cannot answer from anywhere but my work desk. I use call forwarding when I travel so only my office phone number is published. I have VOIP phone service so I can forward calls from the internet if I forget, or need to change where the phone is forwarded. I do have a wired and wireless head set so I can go get a cold drink if on one of those long boring conference calls. I plan my ‘get off from work’ time and try to stick to it, as with any job some days I am late getting off, but it all works out. I make sure my office is for work only, any other computer play time is in a different part of the house on different computer. My office has laptop, dock, couple of monitors, multipurpose printer, fax, scanner, file cabinets – just like the office at a company. I just also happen to have a couple of golden retrievers that come to work with me and usually lay quietly until 5, and yes they know it is 5pm sometimes before I do. For me, one of the biggest concerns when working from home is not being unproductive, but the danger of never stopping work. You could keep going and going because let’s face it – the company will let you do it, so I set myself up to prevent that and maintain a separateness.

• reference list for non-IT driven algorithmic patterns

  - by Quicker

  I am looking for a reference list for non-IT driven algorithmic patterns (which still can be helped with IT implementations of IT). An Example List would be: name; short desc; reference Travelling Salesman; find the shortest possible route on a multiple target path; http://en.wikipedia.org/wiki/Travelling_salesman_problem Ressource Disposition (aka Regulation); Distribute a limited/exceeding input on a given number output receivers based on distribution rules; http://database-programmer.blogspot.de/2010/12/critical-analysis-of-algorithm-sproc.html If there is no such list, but you instantly think of something specific, please 'put it on the desk'. Maybe I can compile something out of the input I get here (actually I am very frustrated as I did not find any such list via research by myself). Details on Scoping: I found it very hard to formulate what I want in a way everything is out that I do not need (which may be the issue why I did not find anything at google). There is a database centric definition for what I am looking for in the section 'Processes' of the second example link. That somehow fits, but the database focus sort of drifts away from the pattern thinking, which I have in mind. So here are my own thoughts around what's in and what's out: I am NOT looking for a foundational algo ref list, which is implemented as basis for any programming language. Eg. the php reference describes substr and strlen. That implements algos, but is not what I am looking for. the problem the algo does address would even exist, if there were no computers (or other IT components) the main focus of the algo is NOT to help other algo's chances are high, that there are implementions of the solution or any workaround without any IT support out there in the world however the algo could be benefitialy implemented/fully supported by a software application = means: the problem of the algo has to be addressed anyway, but running an algo implementation with software automates the process (that is why I posted it on stackoverflow and not somewhere else) typically such algo implementations have more than one input field value and more than one output field value - which implies it could not be implemented as simple function (which is fixed to produce not more than one output value) in a normalized data model often times such algo implementation outputs span accross multiple rows (sometimes multiple tables), whereby the number of output rows depends on the input paraters and rows in the table(s) at start time - which implies that any algo implementation/procedure must interact with a database (read and/or write) I am mainly looking for patterns, not for specific implementations. Example: The Travelling Salesman assumes any coordinates, however it does not say: You need a table targets with fields x and y. - however sometimes descriptions are focussed on examples with specific implementations very much - no worries, as long as the pattern gets clear

• Spotlight on an office - Nairobi, Kenya

  - by Maria Sandu

  Hi everyone, my name is Joash Mitei. I am a graduate Intern at Oracle Systems Kenya and I will briefly take you through our offices and the working environment here in Nairobi, Kenya. I’ve been with Oracle since February 2012 and I’m responsible for Applications Pre-sales focusing on Oracle EPM and E-Business Suite. My background is Finance and Accounting therefore joining Oracle was almost a totally a different ball game but the transition has been smooth. The Oracle offices here are located on the second floor of Mebank Towers. We moved to the 2nd floor just three months ago from the 5th floor mainly because of the growing workforce. We are covering the whole Eastern Africa region hence diversity in culture is evident. This is a plus since you get to interact with people of very different backgrounds, cultures and ways of thinking. The building itself is on the outskirts of the CBD hence free from the hustle and bustle of the town. The office is split into different sections; there is a main working area which has an open desk design that fosters interaction between colleagues, there are 4 conference rooms for meetings and presentations, there are 3 quiet rooms for a little privacy when needed and there is a dining area for meals and ‘hanging out’. The working environment is world-class, to say the least. The employees are very professional, quite smart and needless to say, very busy. There are 4 interns covering sales and pre-sales in both Tech and Apps. As an intern you get support from your supervisor but you are required to show initiative yourself and thus the need to be very pro-active and inquisitive. The local management is well structured and communicative to ensure effectiveness and efficiency in the office. Apart from the daily work, we usually have events to boost staff morale such as ‘TGIF hang -out’, football matches against each other or versus other companies, and team building retreats. All these are monumental in fostering the RED POTENTIAL. We also do numerous CSR activities in the local communities . Well, that’s the Kenyan office for you. Glad to be your tour guide. Have a superb day!

• Spotlight on an office - Moscow

  - by Maria Sandu

  Probably the most famous place in Moscow, after Red Square, is the centre of Moscow. Here you can find beautiful buildings that seem to touch the sky, located on the banks of the river. In one of these high towers you can find the Oracle offices, friendly and modern. The stunning view will keep capture your attention for a couple of minutes and then you can enjoy a delicious coffee and take a seat at your desk, starting a new day. My name is Dmitry and I can tell you that we’re enjoying every minute spent in the office and that’s because of the pleasant atmosphere. As soon as you enter the offices, the friendly environment will make you feel more relaxed. Even though the space is split between the different departments, we interact and communicate a lot. We take our cup of coffee or tea together and discuss our achievements and all sort of subjects in the kitchen or in the open space. One of my favorite parts are the festive events when we celebrate with cakes and goodies. Any birthday or new arrival is a good reason for a tea party! We have some work-related traditions that help us as employees. One of them is the monthly Tech Hour when Experts from the Pre-sales team discuss technical topics and about the most recent innovations within the company. Lunch is another good opportunity to interact and chat. We have a variety of options, such as the two kitchens or the vast number of restaurants where you can serve up anything you want. As we are right in the centre of Moscow, you can choose between Sushi, Italian Pasta and all sorts of food. We usually go with our colleagues to have lunch. If you care about your health, I have very good news for you as nearby there are two first-class fitness centres with swimming pools, yoga and various sport classes that you can attend. My suggestion would be to either start or end your day with a visit to the swimming pool for a well-deserved hour of relaxation. As I mentioned before, we’re right in the heart of Moscow, so after work you can spend some time in the large shopping centers where you can choose between many different entertainment options. We often go to bowling or to the cinema. I hope I have given you a glimpse into working life at the Oracle offices in Moscow, a really great and pleasant place to work in, so follow us on http://campus.oracle.com for our latest vacancies and internships.

• Usage of Pirated software at a company

  - by hakesh

  Hi, I am redirected from stack over flow since the topic is ethics rather than about programming. Thank you for letting me know that. and please give me advices. So, I started to work at a company as an engineer a couple of months ago. It's a small company and what they basically do is answering service on phones. Now they are switching from normal phones to IP phones so that computers take more important place in the work. However, all the computers used by workers are equipped with pirated software ,even their operating systems are. Moreover, they don't even buy one license to make copies for other computers. In other words, they do not spend any money for the software in office. I am not saying copying a licensed one is legit, but the situation is too much. There is one guy who did installing those pirated soft. He does not feel any sense of guilt and even justified when I asked about it. and he is not even a specialist. He just searched on the internet to install pirated software. Our boss does not have any knowledge of computers, so he took cheaper way. How do you guys think about this? Since I am still new to the company, I am not doing maintenance or managing on those cracked computers. But I have to use those software daily. And later on I will be doing support, help desk kind of staff. I really don't want to take responsibility for operating pirated software. and from an aspect of developer and engineer, pirated software are not able to get legal support and it may work unexpectedly. So, I am thinking about changing job. Am I thinking too much? should I wait until I have more credit from the boss and try to change his policy? So far, the boss does not take any words from me. Any opinions are welcome. Thank you

• Help yourself . if you like

  - by rachelp

  At Red Gate we enjoy talking to our customers. Really! If you've read recent blog posts by members of some of our customer-facing teams, you'll have spotted the pleasure they take in their work. In case you missed those posts, here they are: From our Finance team: Finance: Friends, not foes! From our reception desk: The Front line of Communication However, we recognise that sometimes our customers would like to be able to solve their problems or answer their questions without talking to us - they're in a hurry, it's outside office hours . or perhaps they just prefer not to pick up the phone and call.   Self-service customer care So we've begun a programme of work to enable more self-service; whether it's finding the answer to a "how do i.?" question or getting access to a record of what product licenses they own, we want to make it much easier for our customers to get hold of this information for themselves. If they want to.   Phase 1: make it easier to find information We decided to start by tackling findability. We've got loads of useful information on our website, but it's sometimes difficult to find, so we've been working on improving our site search. Step 1 has been to replace the search engine, clean up the search UI, and make it consistent across the site. We're nearly there! The idea is that if we improve the site search it will be easier - and much more pleasant - for people to find the information they need. The new search will go live some time in April, and then we'll be gathering feedback, looking at web analytics (more about this in an earlier article), and working out what improvements we still need to make. We'd love to hear what you think, so do give your feedback or drop us a line. Or pick up the phone and call, if you like.   What do you think? While I've got your attention, I'd love to hear what people think about self-service customer care. Do you like to call, email, live chat . or do you prefer to dig around and find out answers yourself? Who's getting it right: what self-service sites do you like? p.s. Watch this space for news of phase 2.

• Oracle Application Server Performance Monitoring and Tuning (CPU load high)

  - by Berkay

  Oracle Application Server Performance Monitoring and Tuning (CPU load high) i have just hired by a company and my boss give me a performance issue to solve as soon as possible. I don't have any experience with the Java EE before at the server side. Let me begin what i learned about the system and still couldn't find the solution: We have an Oracle Application Server (10.1.) and Oracle Database server (9.2.), the software guys wrote a kind of big J2EE project (X project) using specifically JSF 1.2 with Ajax which is only used in this project. They actively use PL/SQL in their code. So, we started the application server (Solaris machine), everything seems OK. users start using the app starting Monday from different locations (app 200 have user accounts,i just checked and see that the connection pool is set right, the session are active only 15 minutes). After sometime (2 days) CPU utilization gets high,%60, at night it is still same nothing changed (the online user amount is nearly 1 or 2 at this time), even it starts using the CPU allocated for other applications on the same server because they freed If we don't restart the server, the utilization becomes %90 following 2 days, application is so slow that end users starts calling. The main problem is software engineers say that code is clear, and the System and DBA managers say that we have the correct configuration,the other applications seems OK why this problem happens only for X application. I start copying the DB to a test platform and upgrade it to the latest version, also did in same with the application server (Weblogic) if there is a bug or not. i only tested by myself only one user and weblogic admin panel i can track the threads and dump them. i noticed that there are some threads showing as a hogging. when i checked the manuals and control the trace i see that it directs me the line number where PL/SQL code is called from a .java file. The software eng. says that yes we have really complex PL/SQL codes but what's the relation with Application server? this is the problem of DB server, i guess they're right... I know the question has many holes, i'd like to give more in detail but i appreciate the way you guide me. Thanks in advance ... Edit: The server both in CPU and Memory enough to run more complex applications

• Installing OpenLDAP on Fedora 12: ldap_bind: Invalid credentials (49)

  - by Arcturus

  Hello. I've been trying to set up the OpenLDAP installed by default on Fedora 12, very unsuccessfully. My ultimate goal is to use LDAP authentication for user login and Apache, using the OpenLDAP server running on the same machine. The server is running, but the error I always get when I try to use ldapsearch or ldapadd is: ldap_bind: Invalid credentials (49) I've been following these tutorials, but none of them helped me: http://www.howtoforge.com/openldap_fedora7 http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-ldap-quickstart.html http://www.howtoforge.com/linux_ldap_authentication http://docs.fedoraproject.org/deployment-guide/f12/en-US/html/s1-ldap-pam.html http://www.openldap.org/doc/admin24/quickstart.html First, some components were already installed, and I installed these with yum: yum install openldap-servers openldap-devel Then, I created a basic slapd.conf file in /etc/openldap: database bdb suffix "dc=sniejana-sandbox,dc=com" rootdn "cn=root,dc=sniejana-sandbox,dc=com" rootpw {SSHA}cxdz55ygPu4T3ykg7dgu+L0VRvsFSeom directory /var/lib/ldap/sniejana-sandbox.com I obtained the rootpw with this command: slappasswd -s changeme I also created the /var/lib/ldap/sniejana-sandbox.com directory and made sure the entire contents of /var/lib/ldap were owned by the ldap user. I found two ldap.conf files, one in /etc and one in /etc/openldap. I don't know which is the right one. If I understood correctly, this file is to configure the client. I put this in both: HOST localhost BASE dc=sniejana-sandbox,dc=com I then ran the server with: service slapd start It said OK. Most of the tutorials above say to use the command ldapsearch -D "cn=Manager,dc=my-domain,dc=com" -W to ensure that everything's working. When I execute this command, a password prompt appears, and after entering the password, I get the error. ldapsearch -D "cn=root,dc=sniejana-sandbox,dc=com" -W Enter LDAP password: ldap_bind: Invalid credentials (49) The same thing happens when trying to use ldapadd. I tried with an encrypted and unencrypted password in slapd.conf, it doesn't change anything. Adding a -x for simple authentication doesn't change anything either. netstat -ap confirms the server is listening: tcp 0 0 *:ldap *:* LISTEN 4148/slapd tcp 0 0 *:ldap *:* LISTEN 4148/slapd ps -ef|grep slapd confirms the process is running: ldap 4148 1 0 15:22 ? 00:00:00 /usr/sbin/slapd -h ldap:/// -u ldap Running slaptest procudes config file testing succeeded. I read somewhere that the command ldapsearch -x -b '' -s base '(objectclass=*)' namingContext can confirm the server is running. It appears to work: # extended LDIF # # LDAPv3 # base <> with scope baseObject # filter: (objectclass=*) # requesting: namingContext # # dn: # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 I'm running out of ideas. Am I missing something obvious?

• How do multiple displays work on a AMD 785G / ATI HD 4200 motherboard?

  - by aireq

  I just ordered a ASUS M4A785TD-V EVO which has the AMD 785G chipset and HD4200 integrated graphic. The board has VGA, DVI, and HDMI outputs. I'm wondering how many outputs I can run at once, and from what connectors? My guess is that I can only use the VGA, and either the DVI or the HDMI in a dual setup. But not the HDMI and the DVI at the same time. Is this correct? If I have devices plugged into both the HDMI and the DVI ports is there a way to choose between which port I want to use? I have a dual 19" monitor setup, as well as a LCD TV. I'd like to run the VGA and the DVI into my two monitors, and then the HDMI to my TV. Then when I want to watch something on the TV I'd like to be able to switch over from the DVI to the HDMI. Is this possible with out crawling under my desk and unplugging/plugging things in? Update I found the following in the manual off ASUS's website, which confirms my original suspicion that HDMI and DVI can't be used at the same time. But I'd still like to know if it's possible through software to switch between using the HDMI and DVI.

• How to restrict file system when logged into terminal services

  - by pghcpa

  What I need to accomplish: With one login, when user is physically in the building I need them to see everything. When they are using terminal services with same login they should not be able to see the file system on the network. I can lock down the PC running terminal services as that is its only use. Details: Windows/2003 Server with terminal services. One login for a user (e.g., johndoe). When johndoe logs into the network at his desk in the office, he can see the network files according to group policy. When johndoe logs into terminal services from outside the building, we do not want to allow him see the network. Using 2x to do a published app, but that app has a "feature" that allows user to see network. Published application on termina services (only) is a document management system that is tied to windows login, so I can't give them two logins. With one login, when they are in the building I need them to see everything. When they are using terminal services they should not be able to see the network. I can lock down the PC running terminal services as that is its only use.
