• Recommended RAM and disc space for Oracle 11g on Windows

  - by Álvaro G. Vicario

  I need to provide the recommended amount of RAM and disc space (divided in two partitions) so the customer can create an appropriate virtual machine to run Oracle. All I could find in the documentation was a brief listing with minimum RAM and typical/advanced install types. The virtual machine will run latest Oracle Standard Edition One (11g release 2 so far) under Windows Server 2008 x64 and will host a reasonably low traffic web application. How much RAM and disc must I ask for in order to be safe? (Feel free to ask for further details if I've omitted something relevant.) Update: Rough estimations: Database size: 10 MB after installation Growth rate: +3MB per day on average Size of database 'active' data: (not sure of what this means, there's not actual archive so I guess all data is current) Amount of data written per second in peak hours: a few KB Number of client sessions: 3 or 4 at most Frequency and response size of most heavy requests: some reports make heavy table JOINS that need up to 20 seconds to complete but they won't return more than a few thousand rows with plain text. The app also handles BLOBs (typical size from 50KB to 200KB)

• php server settings for restrict post queries

  - by Korjavin Ivan

  I have php script on hosting, which receive big data with ajax/post. Just now, after some works on hosting, I see that script is broken. I checked with curl: file temp1: user_avatar=&user_baner=&user_sig=.... 237 chars total, and curl -H "X-Requested-With: XMLHttpRequest" -X POST --data @temp1 'http://host/mypage.php' works perfect. But with file temp2: name=%D0%9C%D0%B5%D0%B1%%B5%D0%BB%D1%8C%D0%A4%%B0%D0%B1%D1%80%D0%B8%D0%BA%D1%8A&user_payed=0000-00-00&...positions%5B5231%5D=on total chars: 65563 curl -H "X-Requested-With: XMLHttpRequest" -X POST --data @temp2 'http://host/mypage.php' curl return nothing. Looks like a problem with apache/php/php.ini or something like that. I check .htaccess php_value post_max_size 20M Which other parameters I should check? Is it possible that %BO encode kill php/apache? Or total number of parameters (about 2800) ?

• Version control and branching when using Oracle

  - by Ed Woodcock

  Hi folks: At work we're using Oracle and C#/ASP.net to handle a customer's website, this site is very large-scale so the database is very large. We use Perforce for our version control, and tack create or replace scripts to FogBugz cases whenever a database change, which has been fine until now, as we are now at a point where five developers are working on five expansions for the system, each on a seperate Perforce branch. Unfortunately, we cannot get duplicate databases, due to the database size, so everyone is still working from the same one. This is obviously a cause of problems: only ten minutes ago we had a bit of an issue where a stored procedure change for a branch propagated over to the Pre-Production server and caused a large number of crashes for the testers. Ideally, we would like a way to track these changes without having to manually keep track of them through FogBugz. My question is: how do you lot handle this situation? I'm sure there must be a good way by now to handle versioning, or at least tracking changes, in an Oracle database.

• Why are there tons of PHP processes open on my server?

  - by fiftyeight

  Today I saw that a website of mine isn't working so I ssh'd to the server and executed ps -eF. I see about 200 PHP processes that are running all for 4 hours. Apache is built with mpm event and mod fcgid. I killed all the PHP processes and now it's running fine, why does this happen? is this expected behavior? I don't really understand how processes how Apache keeps track of the number of PHP processes and their process IDs, so it would be nice if someone can also give some reference when I can read about this. Also, I used the "ab" command (Apache Benchmark) to see if this happens all the time, so I ran it about 4-5 times with 30 concurrent requests and again there are like 150 PHP processes running, when I keep running "ab" now it doesn't spawn more processes and the website is still working. Please shed some light on this! Thank you :)

• Set default expand/colapse state on pivot tables

  - by CLockeWork

  The Setup I have a pivot table in tabular form pulling data from an Analysis Services Cube. I want to calculate the number of days between two dates, but the setup will only allow me to pull in all date elements, not just the date. I’ve been able to deal with this easily enough by just grouping all the columns: The Problem The default state for the expand/collapse buttons in the image above is often collapsed, but that means the dates I need aren’t there and you have to open the group and manually expand them. This also happens in some random ways (as shown in the image) where only some rows expand. The Question I need a way to set these sections to always be expanded, so that the user never has to open the group to expand the rows. Ideally I’d like to avoid VBA because our end users often block it, but if that’s what’s needed then so be it. Is there a way to set my pivot table to never collapse it’s predefined groups? Note the end user is using Excel 2010

• is it possible to execute keyboard input programmaticly in linux?

  - by Taylor Hawkes

  For example is there a Linux command or way that I could from a program (c++ | python| or other) enter a serious of keyboard inputs that are interpreted as though they are keyboard inputs. I have a bad case of RSI from typing. To ease my pain I developed a voice controlled interface using pocket sphinx and a custom grammar and to run a number of very common commands. ex: "open chrome" , "open vim". basically what is shown here, but with slightly diff tools: http://bloc.eurion.net/archives/2008/writing-a-command-and-control-application-with-voice-recognition/ I have run into some limitation as I can only execute command line commands given a voice command. Rather than having a "voice command" - "command line command" mapping I would like to have "voice command" - "keyboard input" mapping. So when my active window is a browser and i type + n, and new tab opens. If i'm in vim and new vim tab opens. Any suggestions, ideas, tools or approaches to this problem would be much appreciated. I understand the answer may not be simple, but would like to develop it none the less.

• How can I justify software testing to management?

  - by Nate

  I work for a small company (less than 200 employees) whose software group only makes up a small part of our staff (4 employees, occasionally with a few contractors). The four of us have been making strides in transitioning to better practices, and one of the next logical steps is to improve our testing. As anyone who has done any meaningful tests knows, testing takes a lot of time - and at my company, it takes too much time to justify to management, so we generally do what little we do on the sly. I don't think this is serving us well, as we keep coming up against otherwise avoidable problems when we ship under-tested software. I would like to be able to come to management with a justification for hiring a dedicated software test engineer (someone who can both write automated tests and perform manual ones). Are there any good published studies that show the benefits of adding such a position to a small company? Where can I find information about costs associated with the position? I plan on doing a little number crunching on our own history, but having some external sources to point to would help bolster my case.

• Design pattern for client/server sessions?

  - by nonot1

  Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.

• Use apt-get source on a debian repo without using /etc/apt/source.list

  - by Erwan Queffélec

  I'm trying to use apt-get source as a regular user on a debian squeeze system. I want to retrieve the sources for cyrus-imapd-2.4 from the testing/wheezy repository. apt-get source works without root privileges; however, it seems there is no way to get apt-get to fetch anything from a repository that is not in /etc/apt/sources.list. Is there any command line option, alternate sources.list file, environment variable that will get apt to work with a custom repository ? I do have root access so I could change the /etc/apt/sources.list, however I really do not want to do that for a number of reason.

• .NET vs Windows 8: Rematch!

  - by Simon Cooper

  So, although you will be able to use your existing .NET skills to develop Metro apps, it turns out Microsoft are limiting Visual Studio 2011 Express to Metro-only. From the Express website: Visual Studio 11 Express for Windows 8 provides tools for Metro style app development. To create desktop apps, you need to use Visual Studio 11 Professional, or higher. Oh dear. To develop any sort of non-Metro application, you will need to pay for at least VS Professional. I suspect Microsoft (or at least, certain groups within Microsoft) have a very explicit strategy in mind. By making VS Express Metro-only, developers who don't want to pay for Professional will be forced to make their simple one-shot or open-source application in Metro. This increases the number of applications available for Windows 8 and Windows mobile devices, which in turn make those platforms more attractive for consumers. When you use the free VS 11 Express, instead of paying Microsoft, you provide them a service by making applications for Metro, which in turn makes Microsoft's mobile offering more attractive to consumers, increasing their market share. Of course, it remains to be seen if developers forced to jump onto the Metro bandwagon will simply jump ship to Android or iOS instead. At least, that's what I think is going on. With Microsoft, who really knows?

• Understanding Visitor Pattern

  - by Nezreli

  I have a hierarchy of classes that represents GUI controls. Something like this: Control-ContainerControl-Form I have to implement a series of algoritms that work with objects doing various stuff and I'm thinking that Visitor pattern would be the cleanest solution. Let take for example an algorithm which creates a Xml representaion of a hierarchy of objects. Using 'classic' approach I would do this: public abstract class Control { public virtual XmlElement ToXML(XmlDocument document) { XmlElement xml = document.CreateElement(this.GetType().Name); // Create element, fill it with attributes declared with control return xml; } } public abstract class ContainerControl : Control { public override XmlElement ToXML(XmlDocument document) { XmlElement xml = base.ToXML(document); // Use forech to fill XmlElement with child XmlElements return xml; } } public class Form : ContainerControl { public override XmlElement ToXML(XmlDocument document) { XmlElement xml = base.ToXML(document); // Fill remaining elements declared in Form class return xml; } } But I'm not sure how to do this with visitor pattern. This is the basic implementation: public class ToXmlVisitor : IVisitor { public void Visit(Form form) { } } Since even the abstract classes help with implementation I'm not sure how to do that properly in ToXmlVisitor. Perhaps there is a better solution to this problem. The reason that I'm considering Visitor pattern is that some algorithms will need references not available in project where the classes are implemented and there is a number of different algorithms so I'm avoiding large classes. Any thoughts are welcome.

• Why is it that software is still easily pirated today?

  - by mohabitar

  I've always been curious about this. Now I wouldn't call myself a programmer yet, but I'm learning, so maybe the answer to this is obvious. It just seems a little hard to believe that with all of our technological advances and the billions of dollars spent on engineering the most unbelievable and mind-blowing software, we still have no other means of protecting against piracy then a "serial number/activation key". I'm sure a ton of money, maybe even billions, went into creating Windows 7 or Office and even Snow Leopard, yet I can get it for free in less than 20 minutes. Same for all of Adobe's products, which are probably the easiest. I guess my question is: can there exist a fool proof and hack proof method of protecting your software against piracy? If not realistically, how about theoretically possible? Or no matter what mechanisms these companies deploy, hackers can always find a way around it? EDIT: So apparently, the answer is no. There's pretty much no way. And so I'm sure these big companies have realized this as well. Should they adopt another sales model rather than charging a crapload for their software (I know its justified and they put a lot of hard work into their software, but its still a lot of money). Are there any alternative solutions that will benefit both the company and the user (i.e. if you purchase our product, we'll apply $X dollars to your account that will apply to future purchases from our company)?

• How to change a function/formula in a whole column where I also have empty cells

  - by Zvi

  I have a column with a formula/function that has other cells as parameters. However in the column, every few rows I have a subtotal and blanks, for readability. Now I decided to change the formula/function but I can not do copy+paste on the whole column because of the subtotals/blank cells, and I can not do change+replace because there are parameters in the functions that uses other cells and thus it is different in each cell in the column. For example, if the formula is =if(A5>24,1,"") and I want to change it to =AA_userfn(A5,B5) Any idea how to change it easily? currently I copy+paste few rows at a time, but that is tedious. Maybe a Sub that will go all over the column (the column number as an input parameter) and looks for =if(, and then replaces it with =aa_userfn(Ax, By) where Ax and By are calculated based on the position of the cell currently changed in reference to the previous values in that cell. Any ideas will be welcomed

• How do you decide what kind of database to use?

  - by Jason Baker

  I really dislike the name "NoSQL", because it isn't very descriptive. It tells me what the databases aren't where I'm more interested in what the databases are. I really think that this category really encompasses several categories of database. I'm just trying to get a general idea of what job each particular database is the best tool for. A few assumptions I'd like to make (and would ask you to make): Assume that you have the capability to hire any number of brilliant engineers who are equally experienced with every database technology that has ever existed. Assume you have the technical infrastructure to support any given database (including available servers and sysadmins who can support said database). Assume that each database has the best support possible for free. Assume you have 100% buy-in from management. Assume you have an infinite amount of money to throw at the problem. Now, I realize that the above assumptions eliminate a lot of valid considerations that are involved in choosing a database, but my focus is on figuring out what database is best for the job on a purely technical level. So, given the above assumptions, the question is: what jobs are each database (including both SQL and NoSQL) the best tool for and why?

• MSDeploy - possible to call setAcl on multiple destinations in one go?

  - by growse

  I'm building a nice little continuous integration environment for our development team, based on TeamCity. It's working rather nicely, as it can build a mix of .NET and PHP projects, and push them to our internal and external platforms. I'm primarily using MsDeploy to push everything to the internal platform, as that's all IIS based. However, there's a number of builds where I need to set directory permissions on the destination directory. I can use the setAcl operator just fine, but that only seems to take a single destination as an argument. Therefore, if I need to alter the permissions on 5 destination directories, I need to call MsDeploy 5 times, which seems a lot of overhead. Is there a sensible way around this? Reading the documentation, I don't think MsDeploy takes more than a single argument for the setAcl operator, but could be wrong. Is there a better way for a build server to set multiple directory permissions in one go?

• Message Driven Bean JMS integration

  - by Anthony Shorten

  In Oracle Utilities Application Framework V4.1 and above the product introduced the concept of real time JMS integration within the Framework for interfacing. Customer familiar with older versions of the Framework will recall that we used a component called the Multi-purpose Listener (MPL) which was a very light service bus for calling interface channels (including JMS). The MPL is not supplied with all products and customers prefer to use Oracle SOA Suite and native methods rather then MPL. In Oracle Utilities Application Framework V4.1 (and for Oracle Utilities Application Framework V2.2 via Patches 9454971, 9256359, 9672027 and 9838219) we introduced real time JMS integration natively for outbound JMS integration and using Message Driven Beans (MDB) for incoming integration. The outbound integration has not changed a lot between releases where you create an Outbound Message Type to indicate the record types to send out, create a JMS sender (though now you use the Real Time Sender) and then create an External System definition to complete the configuration. When an outbound message appears in the table of the type and external system configured (via a business event such as an algorithm or plug-in script) the Oracle Utilities Application Framework will place the message on the configured Queue linked to the JMS Sender. The inbound integration has changed. In the past you created XAI Receivers and specified configuration about what types of transactions to process. This is now all configuration file driven. The configuration files for the Business Application Server (ejb-jar.xml and weblogic-ejb-jar.xml) define Message Driven Beans and the queues to monitor. When a message appears on the queue, the MDB processes it through our web services interface. Configuration of the MDB can be native (via editing the configuration files) or through the new user exit capabilities (which is aimed at maintaining custom configuration across upgrades). The latter is better as you build fragments of configuration to make it easier to maintain. In the next few weeks a number of new whitepaper will be released to illustrate the features of the Oracle WebLogic JMS and Oracle SOA Suite integration capabilities.

• Calculating the "power" of a player in a "Defend Your Castle" type game

  - by Jesse Emond

  I'm a making a "Defend Your Castle" type game, where each player has a castle and must send units to destroy the opponent's castle. It looks like this (and yeah, this is the actual game, not a quick paint drawing..): Now, I'm trying to implement the AI of the opponent, and I'd like to create 4 different AI levels: Easy, Normal, Hard and Hardcore. I've never made any "serious" AI before and I'd like to create a quite complete one this time. My idea is to calculate a player's "power" score, based on the current health of its castle and the individual "power" score of its units. Then, the AI would just try to keep a score close to the player's one(Easy would stay below it, Normal would stay near it and Hard would try to get above it). But I just don't know how to calculate a player's power score. There are just too many variables to take into account and I don't know how to properly use them to create one significant number(the power level). Could anyone help me out on this one? Here are the variables that should influence a player's power score: Current castle health, the unit's total health, damage, speed and attack range. Also, the player can have increased Income(the money bag), damage(the + Damage) and speed(the + speed)... How could I include them in the score? I'm really stuck here... Or is there an other way that I could implement AI for this type of game? Thanks for your precious time.

• Iptables massive 1:1 NAT

  - by TiFFolk

  I have to connect two LANs: LAN1: 10.10.0.0/16 and LAN2: 192.168.0.0/16. I can't do simple routing, because 192.168.0.0/16 net is prohibited in LAN1, so I am thinking of using Full cone nat (1:1) to translate 192.168.x.y/16 to 10.11.x.y/16. Each translation is done by this rules: iptables -t nat -A PREROUTING -d 10.11.0.0/16 -j DNAT --to-destination 192.168.0.0/16 iptables -t nat -A POSTROUTING -s 192.168.0.0/16 -j SNAT --to-source 10.11.0.0/16 But I will have to enter 254*254*2 rules, what will, I think, result in enormous performance degradation. So, is there a way to write such one-to-one translation with minimum number of rules?

• How should developers handle subpar working conditions? [closed]

  - by ivar

  I have been working in my current job for less than a year and at the beginning didn't have the courage to say anything about the things that bothered me. Now I'm a bit fed up and need things to get better. The first problem is not random but I'll mention it anyway. We are running out of space so every new employee gets a smaller table. We are promised that the space problem will be fixed soon. Almost every employee has a different keyboard, mouse, headphones (if any). Mine are $10 keyboard, some random cheap mouse and some random crappy headphones with a mic. All these were used and dirty when I got them. The number of monitor is 1-3 and with different sizes. I have 2 nice monitors and can't complain but some are given 1 small monitor. When it's their first job they don't have the guts to ask for 2 even if most others have 2. Nobody seems to care too. Project manager asked if it's ok? He obviously said he can handle the 1 small one. Then the manager said you can go ask for 1 more. I'm watching this and think go and ask where? The company is trying to hire more people but is not doing much after the person has signed the contract. We are put in one room that is open to the hallway and it's super noisy. Almost like a zoo at times. Even if nobody is talking the crappy keyboards make too much noise. Is this normal? Am I too negative and should I just do my job with what I was given? Should I demand better things? Should the company have some system that everybody gets things in some price range?

• FrameworkFolders support for WebCenter Portal

  - by Justin Paul-Oracle

  Oracle WebCenter Content Server includes components that provide a hierarchical folder interface, similar to a conventional file system, for organizing and managing some or all of the content in the repository. We used Contribution Folders (folders_g) which is being replaced by the new Folders (FrameworkFolders) component. The newer FrameworkFolders component fixes a number of limitations that folders_g had and adds a ton of new features. If you have played with the WebCenter Content mobile app, you will notice that it uses FrameworkFolders too. WebCenter Portal requires the use of the folders_g component. Given the fact that folders_g and FrameworkFolders component do not go well together and must never be enabled together on any system, you could never use the new features if you planned to use integrate Content with Portal. I still remember presenting a demo with a colleague for a client and he was showing off the mobile capabilities in Portal (which are pretty impressive by the way) and was getting all the glory; while I was sitting back wanting to show off the Content app but could not (no FrameworkFolders). Not any more; Oracle has released bundle patches for both WebCenter Content and Portal in April 2014 which bring home the support for FrameworkFolders. These patches will bring these products to version 11.1.1.8.3. You can enable support for FrameworkFolders on new Content and Portal installations where the folders_g component has never been enabled using the following patches: Download and apply the WebCenter Content MLR03 patch 18088049. Download and apply the WebCenter Portal BP3 patch 18085041. Download and apply the WebCenterConfigure component patch 18387955. Before applying this patch on the Content Server ensure that WebCenter Content MLR03 patch 18088049 has already been applied. You can find detailed instructions on how to enable FrameworkFolders support in the Oracle® Fusion Middleware Installation Guide for Oracle WebCenter Portal 11g Release 1 (11.1.1.8.3). There may be another bundle patches release (version 11.1.1.8.4) for many FMW products (including WebCenter Portal) in July 2014 which could further enhance the FrameworkFolders support.

• How to create single integer index value based on two integers where first is unlimited?

  - by Jan Doggen

  I have table data containing an integer value X ranging from 1.... unknown, and an integer value Y ranging from 1..9 The data need to be presented in order 'X then Y'. For one visual component I can set multiple index names: X;Y But for another component I need a one-dimensional integer value as index (sort order). If X were limited to an upper bound of say 100, the one-dimensional value could simply be X*100 + Y. If the one-dimensional value could have been a real, it could be X + Y/10. But if I want to keep X unlimited, is there a way to calculate a single integer 'indexing' value from X and Y? [Added] Background information: I have a Gantt/TreeList component where the tasks are ordered on a TaskIndex integer. This does not need to be a real database field, I can make it a calculated field in the underlying client dataset. My table data is e.g. as follows: ID Baseline ParentID 1 0 0 (task) 5 2 1 (baseline) 8 1 1 (baseline) 9 0 0 (task) 12 0 0 (task) 16 1 12 (baseline) Task 1 has two baselines numbered 1 and 2 (IDs 8 and 5) Task 9 has no baselines Task 12 has one baseline numbered 1 (ID 16) Baselines number 1-9 (the Y variable from my question); 0 or null identify the tasks ID's are unlimited (the X variable) The user plays with visibility of baselines, e.g. he wants to see all tasks with all baselines labeled 1. This is done by updating a filter on the table. Right now I constantly have to recalculate TaskIndex after changing the filter (looping through records). It would be nice if TaskIndex could be calculated on the fly for each record knowing only the data in the current record (I work in Delphi where a client dataset has an OnCalcFields event handler, that is triggered for each record when necessary). I have no control over the inner workings of the visual component.

• What are the maths behind 'Raiden 2' purple laser?

  - by Aybe

  The path of the laser is affected by user input and enemies present on the screen. Here is a video, at 5:00 minutes the laser in question is shown : Raiden II (PS) - 1 Loop Clear - Part 2 UPDATE Here is a test using Inkscape, ship is at bottom, the first 4 enemies are targeted by the plasma. There seems to be a sort of pattern. I moved the ship first, then the handle from it to form a 45° angle, then while trying to fit the curve I found a pattern of parallel handles and continued so until I reached the last enemy. Update, 5/26/2012 : I started an XNA project using beziers, there is still some work needed, will update the question next week. Stay tuned ! Update : 5/30/2012 : It really seems that they are using Bézier curves, I think I will be able to replicate/imitate a plasma of such grade. There are two new topics I discovered since last time : Arc length, Runge's phenomenon, first one should help in having a linear movement possible over a Bézier curve, second should help in optimizing the number of vertices. Next time I will put a video so you can see the progress 8-)

• OSB and Ubuntu 10.04 - Too Many Open Files

  - by jeff.x.davies

  When installing the latest Oracle Service Bus (11gR1PS3) onto my Ubuntu 10.04 system, the Eclipse IDE was complaining about there being too many open files. The Oracle Service Bus and the Oracle Enterprise Pack for Eclipse (aka OEPE) do make use of ALOT of files. By default, Ubuntu will restrict each user to 1024 open files. A much more realistic number for OSB development is 4096. Changing the file limit in Ubuntu is fairly simple (if arcane). You will need to modify two different files and then restart your server. First, you need to modify the limits.conf file as the root user. Open a terminal window and enter the following command: sudo gedit /etc/security/limits.conf Add the following 2 lines to the file. The asterisk simply means that the rule will apply to all users. * soft nofile 4096 * hard nofile 4096 Save your changes and close gedit. The second file to change is the common-session file. Use the following command: sudo gedit /etc/pam.d/common-session Add the following line: session required pam_limits.so Save the file and exit gedit. Restart your machine. You shouldn't have any more problems with too many open files anymore.
