  • Solution for ora-1017 error for odp.net 2.111.7.0 ?

    - by Prithis
    Hi, As you are aware Oracle 11g has new facility of case sensitive password. We want to make use of it. When my C# application connects to oracle databse using ODP.Net 2.111.7.0 I am getting ora-1017 error. When we switch off this case sensitive feature it works without any change to the connection string. Any idea what is missing? is there any escape sequence we can use to specify lowercase characters in password? Thanks

  • using ansi sql syntax for formatting Numeric

    - by changed
    Hi I am using two different databases for my project. Oracle and apache derby and trying to use as much as possible ansi sql syntax supported by both of the databases. I have a table with column amount_paid NUMERIC(26,2), in a table. My old code which was using oracle db need to retrieve value in this format SELECT LTRIM(TO_CHAR(amount_paid,'9,999,999,999,999.99')) . How can i do this using ANSI sql syntax.

  • What is the network address (x.x.x.0) used for?

    - by Shtééf
    It appears to be common practice to not use the first address in a subnet, that is the IP 192.168.0.0/24, or a more exotic example would be 172.20.20.64/29. The ipcalc tool I frequently use follows the same practice: $ ipcalc -n -b 172.20.20.64/29 Address: 172.20.20.64 Netmask: 255.255.255.248 = 29 Wildcard: 0.0.0.7 => Network: 172.20.20.64/29 HostMin: 172.20.20.65 HostMax: 172.20.20.70 Broadcast: 172.20.20.71 Hosts/Net: 6 Class B, Private Internet But why is that HostMin is not simply 64 in this case? The 64 address is a valid address, right? And whatever the answer, does the same apply to IPv6? Perhaps slightly related: it also appears possible to use a TCP port 0 and an UDP port 0. Are these valid or used anywhere?

  • PHP, PEAR, and oci8 configuration

    - by zack_falcon
    I'll make this quick. I installed Oracle 11g (with appropriate database, users, etc), Apache 2.4.6, and PHP 5.5.4 on a Fedora 19 system. I wanted to connect PHP to Oracle. What I really wanted to do was to download MDB2_Driver_oci8, which I thought would be easy, but before I can do such a thing, PHP needs to have that plug-in enabled, so here's what I did: Tried to install oci8 via the following: pecl install oci8 When that didn't exactly work the first few times, I figured out I, for some reason, needed "Development tools" - via yum groupinstall "Development Tools" Then I figured out later that PHP actually doesn't do oci8 - it's PHP Devel. So, I had to install that too, via yum install php-devel. And then, I finally got to install oci8. It asked for the Oracle Directory, and that was that. But it said the following: Configuration option 'php_ini' is not set to php.ini location You should add 'extensions=oci8.so' to php.ini First, I did a locate oci8.so - found it in /usr/lib64/php/modules/ Second, I added what it told me to, to the php.ini file. Third, I checked the usual php_info() test page - no mention of OCI8. Uh-oh. Fourth, running both php -i and php -m listed oci8 as one of the modules. Weird. In desperation, I went ahead and downloaded the MDB2_Driver_oci8. Maybe that will fix things. Nope. When I loaded my PHP Webpage, it returned the following: Error message: extension oci8 is not compiled into PHP As well as: MDB2 error: not found Strange. And then I decided to check the error logs: PHP Startup - unable to load dynamic library '/usr/lib64/php/modules/oci8.so' - libclntsh.so.11.1: cannot open shared object file: No such file or directory in Unknown on line 0 And now I'm stuck. I tried going into the php.ini, and found that the extension_dir was commented out. I put it back in, which only seemed to break stuff. Things of note: I followed this (link) guide on how to configure PHP and install oci8. ./configure --with-oci8 doesn't work. Fedora says no such directory. As both the webpage files and the actual server reside on the same PC, I did not install the Oracle Client files. The extension_dir is commented out by default in the php.ini. This is just one of my problems in a long line of problems concerning the replication of an already existing and working, but dying, setup. It seems whenever I want to solve a problem, I have to do X first. And by doing X, I uncover another problem, which I have to solve by doing Y, which has its own problems, etc, etc. Any help would be much appreciated. Thanks.

  • What does CONTROL mean in the context of the Certificate

    - by Ram
    Hi Everyone, I am trying to implement encryption in sql server 2005 through Certificate and Symmetric Key and i came to know that the application user should have the following access in order to Encrypt and Decrypt Data 1) CONTROL permission on Certificate and 2) REFERENCES on the Symmetric Key (Let me know if i am wrong) Now my concern is what does CONTROL mean in the context of Certificate? If my User1 has Control permission on my certificate Cert1 What all can he do, Is there a way to restrict him further, but user1 still be able to Encrypt\Decrypt the data I could not find any good practice doc for certificate and key management so can some one advice the good practice for this Thanks, Ram

  • How do you hit modifier keys when touch typing?

    - by Bob Ueland
    I am a programmer and I want to learn to touch type. As all programmers know, using modifier keys like Control, Command and Alt are essential. When programming I think that every second or third word I use involves a modifier key. But most touch typing learning software do not address these keys, it is as if they do not exist. Not only do they not let you practice them, they do not even tell you which fingers to use to hit them. Actually there is a touch typing game that I use called StarTyper (http://lidenanna.com) that lets you practice modifier keys and even make up your own custom words containing modifier keys. But not even this game tells you which fingers to use when hitting the modifier keys. Has anybody addressed this problem. Or are there just homespun methods that work for one person but not for the other?

  • HTTP triggers for Postgres

    - by HeineyBehinds
    I'm trying to write a Postgres trigger such that when a configuration table is updated, a backend component is notified and can handle the change. I know that Oracle has the concept of a web/HTTP trigger, where you can execute an HTTP GET from the Oracle instance itself to a URL that can then handle the request at the application layer. I'm wondering if Postgres (v. 9.0.5) has the same feature, or comes with anything similar (and, subsequently, how to set it up/configure it)?

  • Not really a quaestion...but i need help

    - by Dan F.
    I have to make a process in Oracle/PLSQL.....i have to verify that the interval of time between start_date and end_date from a new row that i create must not intersect other start_dates and end_dates from other rows. Now I need to check each row for that condition and if it doesn't correspond the repetitive instruction should stop and after that to display a message such as "The interval of time given is not correct". I don't know how to make repetitive instructions in Oracle/PLSQL and I would appreciate if you would help me.

  • Why is C++ backward compatibility important / necessary?

    - by Giorgio
    As far as understand it is a well-established opinion within the C++ community that C is an obsolete language that was useful 20 years ago but cannot support many modern good programming practices, or even encourages bad practices; certain features that were typical of C++ (C with classes) during the nineties are also obsolete and considered bad practice in modern C++ (e.g., new and delete should be replaced by smart pointer primitives). In view of this, I often wonder why backward compatibility with C and obsolete C++ features is still considered important: to my knowledge there is no 100% compatibility, but most of C and C++ are contained in C++11 as a subset. Of course, there is a lot of legacy code and libraries (possibly containing templates) that are written using a previous standard of the language and which still need to be maintained or used in connection with new code. Nevertheless, maybe it would still be possible to drop obsolete C and C++ features (e.g. the mentioned new / delete) from a future C++ standard so that it is impossible to use them in new code. In this way, old and dangerous programming practices would be quickly banned from new code, and modern, better programming practices would be enforced by the compiler. Legacy code could still be maintained using separate compilation (having C alongside C++ source files is already a common practice). Developers would have to choose between one compiler supporting the old-style C++ that was common during the nineties and a compiler supporting the modern C++? style (the question mark indicates a future, hypothetical revision). Only mixing the two styles would be forbidden. Would this be a viable strategy for encouraging the adoption of modern C++ practices? Are there conceptual reasons or technical problems (e.g. compiling existing templates) that make such a change undesirable or even impossible? Has such a development been proposed in the C++ community. If there has been some extended discussion on the topic, is there any material on-line?

  • Multiple stores for the same niche

    - by pandronic
    I started developing a new niche of products in my country about 3 years ago. That's when I opened my first store. Everything went fine, until a year ago, when someone I thought was a friend secretly stole my idea and made his own competing store. I was pretty upset when I caught him and decided to make it as difficult as possible for him, so I made another 4 stores, trying to get him as low as possible in the search results. The new sites have similar products (although not 100% identical), slightly different titles, images and prices. They look different and are built on different e-commerce platforms. They are all hosted on the same server, have roughly the same backlinks, use the same Google account for Analytics, have the same support phone numbers etc etc. I wasn't thinking that I'm doing something fishy, so I didn't try to hide anything. Trouble is that those sites, after doing fine for a few months, dropped like bricks in search results, almost to the point that they can't be found at all. At the moment, the only site that ranks relatively well is the original one and a couple of secondary pages with no importance from one of the other sites. How did this happen? Does Google have something against this practice? Did they take action by themselves when they realized that I was trying to monopolize this niche, or did my competitor report me for some kind of webspam? And more importantly, what do I do now? Do I shutdown all but my original site and 301 redirect users to it from the others? Can I report my competitor for engaging in the same practice? (He fought back and now he has 3-4 sites, some of which still rank kind of OKish, also he has no idea about web development, SEO or marketing, he just crudely copies what I do and is slowly but surely starting to do better than me).

  • If some standards apply when "it depends" then should I stick with custom approaches?

    - by Travis J
    If I have an unconventional approach which works better than the industry standard, should I just stick with it even though in principal it violates those standards? What I am talking about is referential integrity for relational database management systems. The standard for enforcing referential integrity is to CASCADE delete. In practice, this is just not going to work all the time. In my current case, it does not. The alternative suggested is to either change the reference to NULL, DEFAULT, or just to take NO ACTION - usually in the form of a "soft delete". I am all about enforcing referential integrity. Love it. However, sometimes it just does not fully apply to use all the standards in practice. My approach has been to slightly abandon a small part of one of those practices which is the part about leaving "hanging references" around. Oops. The trade off is plentiful in this situation I believe. Instead of having deprecated data in the production database, a splattering of "soft delete" logic all across my controllers (and views sometimes depending on how far down the chain the soft delete occurred), and the prospect of queries taking longer and longer - instead of all that - I now have a recycle bin and centralized logic. The only tradeoff is that I must explicitly manage the possibility of "hanging references" which can be done through generics with one class. Any thoughts?

  • TDD/Tests too much an overhead/maintenance burden?

    - by MeshMan
    So you've heard it many times from those who do not truly understand the values of testing. Just to start things out, I'm a follower of Agile and Testing... I recently had a discussion about performing TDD on a product re-write where the current team does not practice unit testing on any level, and probably have never heard of the dependency injection technique or test patterns/design etc (we won't even get on to clean code). Now, I am fully responsible for the rewrite of this product and I'm told that attempting it in the fashion of TDD, will merely make it a maintenance nightmare and impossible for the team maintain. Furthermore, as it's a front-end application (not web-based), adding tests is pointless, as the business drive changes (by changes they mean improvements of course), the tests will become out of date, other developers who come on to the project in the future will not maintain them and become more of a burden for them to fix etc. I can understand that TDD in a team that does not currently hold any testing experience doesn't sound good, but my argument in this case is that I can teach my practice to those around me, but further more, I know that TDD makes BETTER software. Even if I was to produce the software using TDD, and throw all the tests away on handing it over to a maintenance team, it surely would be a better approach than not using TDD at all from the start? I've been shot down as I've mentioned doing TDD on most projects for a team that have never heard of it. The thought of "interfaces" and strange looking DI constructors scares them off... Can anyone please help me in what is normally a very short conversation of trying to sell TDD and my approach to people? I usually have a very short window of argument before falling at the knees to the company/team.

  • SO-overflow induced passivity - how to cope?

    - by Ruben
    After not really working on my pet project for a while, I discovered Stackoverflow and upon perusing it more intensely I was quite amazed. I'm a bit of a perfectionist, so when I found eye-openers here highlighting many of the mistakes I made, I first wanted to fix everything. However, it's a pet project for a reason: I'm self-taught and I'm studying psychology, so programming skills can never become priority one (though it often helps, even in this field). Issues that stuck out were numerous security issues (e.g. CSRF-prevention and bcrypt eluded me) not object-oriented (at least the PHP part, the JS-part mostly is) no PHP framework used, so many of my DIY takes on commonly-tackled components (auth, ...) are either bad or inefficient really poor MySQL usage (no prepared statements, mysql extension, heard about setting proper indices two days ago) using mootools even though JQuery seems to be fashionable, so there's more probably always going to be better integration with services I'd like to use (like google visualization) So, my SO-induced frenzy turned into passivity. I can't do it all (soon) in the rather small amount of spare time I can spend on working on my project. I can leave some of the issues be in good conscience (speed stuff: an unfinished & unpublished project will never become popular, right?). No clear conscience without good security though and if I don't use a framework for auth and other complex stuff I'll regret having to do it myself. One obvious answer would probably be going open-source, but I think the project would need to become more impressive before others would commit to it. I can't afford to employ someone either. I do think the project deserves being worked on, though. How should I tackle it anyway? What's the best practice for little-practice people?

  • What are benefit/drawbacks of classifying defects during a peer code review

    - by DXM
    About 3 months ago, our engineering group rolled out Review Board to be used for all peer code reviews. Today, I had a discussion with one of the people involved in that process and found out that we are already looking for a replacement (possibly something commercial) because of several missing features. One of the features that is apparently asked by many people is the ability to classify/categorize each code review comment (i.e. is it a style issue, coding convention, resource leak, logic error, crash... whatever). For those teams that regularly practice code review, is this categorization a common practice? Do you do it? have you done it in the past? Is it good/bad? On one hand, it gives the team some more metrics and possibly will indicate more specific areas where developers may potentially need to be trained in (at least that seems to be the argument). Are there other benefits? And on the other hand, and this is my concern, is that it will slow down code review process that much more. As a team lead, I've done a fairly large share of reviews, and I've always liked the ability, to highlight a chunk of code, hammer off a comment and move on as fast as possible. Although I haven't tried it personally, I have a feeling that expanding that combo box every time and scrolling/searching for the right category would feel like something is tripping you. Also if we start keeping metrics on this stuff, my other concern is that valuable code review meeting time will be spent on arguing whether something is a logic error or if it should be classified as a crash.

  • What are the best practices for phasing out obsolete code?

    - by P.Brian.Mackey
    I have the need to phase out an obsolete method. I am aware of the [Obsolete] attribute. Does Microsoft have a recommended best practice guide for doing this? Here's my current plan: A. I do not want to create a new assembly because developers would have to add a new reference to their projects and I expect to get a lot of grief from my boss and co-workers if they must do this. We also do not maintain multiple assembly versions. We only use the latest version. Changing this practice would require changing our deployment process which is a big issue (have to teach people how to do things with TFS instead of FinalBuilder and get them to give up FinalBuilder) B. Mark the old method obsolete. C. Because the implementation is changing (not the method signature), I need to rename the method rather than create an overload. So, to make users aware of the proper method I plan to add a message to the [Obsolete] attribute. This part bothers me, because the only change I'm making is decoupling the method from the connection string. But, because I'm not adding a new assembly, I see no way around this. Result: [Obsolete("Please don't use this anymore because it does not implement IMyDbProvider. Use XXX instead.")]; /// <summary> /// /// </summary> /// <param name="settingName"></param> /// <returns></returns> public static Dictionary<string, Setting> ReadSettings(string settingName) { return ReadSettings(settingName, SomeGeneralClass.ConnectionString); } public Dictionary<string, Setting> ReadSettings2(string settingName) { return ReadSettings(settingName);// IMyDbProvider.ConnectionString private member added to class. Probably have to make this an instance method. }

  • Review: Data Modeling 101

    I just recently read “Data Modeling 101”by Scott W. Ambler where he gave an overview of fundamental data modeling skills. I think this article was excellent for anyone who was just starting to learn or refresh their skills in regards to the modeling of data.  Scott defines data modeling as the act of exploring data oriented structures.  He goes on to explain about how data models are actually used by defining three different types of models. Types of Data Models Conceptual Data Model  Logical Data Model (LDMs) Physical Data Model(PDMs) He further expands on modeling by exploring common data modeling notations because there are no industry standards for the practice of data modeling. Scott then defines how to actually model data by expanding on entities, attributes, identities, and relationships which are the basic building blocks of data models. In addition he discusses the value of normalization for redundancy and demoralization for performance. Finally, he discuss ways in which Developers and DBAs can become better data modelers through the use of practice, and seeking guidance from more experienced data modelers.

  • GitHub: Are there external tools for managing issues list vs. project backlog

    - by DXM
    Recently I posted one of my the projects1 on GitHub and as I was exploring capabilities of the site, I noticed they have a rather decent issue tracking section. I want to use that section as a) other people can report bugs if they'd like and b) other people can see which bugs I'm aware of. However, as others have noted, issues list cannot be prioritized in order to create a project backlog. For now my backlog has been a text file, but I'd like to be able to have it integrated so the same information isn't maintained in different places. Having a fully ordered list, which is something we also practice at work, has been very useful as I can open one file, start with line 1 and fire off 2 or 3 items in one sitting without having to go back to a full issues/stories bucket. GitHub doesn't offer this. What GitHub does offer is a very nice and clean API so issues can easily be exported into anything else. I've searched to see if there are other websites (like Trello) that integrate with GitHub issues, but did not find anything. Does anyone know of such a product, service or offline tool? Those that use GitHub, what is your experience in managing backlog? I kinda hate the idea of manually managing two disconnected lists like some people seem to be doing with Wiki project pages. 1 - are shameless plugs allowed no this site? Searched but didn't find a definite answer. If it's bad practice, STOP and don't read further As a developer I got sick and tired of navigating to same set of folders 30 times a day, so I wrote a little, auto-collapsible utility that gets stuck to the desktop and allows easy access to the folders you constantly use.

  • What do you do if you reach a design dead-end in evolutionary methods like Agile or XP?

    - by Dipan Mehta
    As I was reading Martin Fowler's famous blog post Is Design Dead?, one of the striking impressions I got is that given the fact that in Agile Methodology and Extreme Programming, the design as well as programming is evolutionary, there are always points where things need to get refactored. It may be possible that when a programmer's level is good, and they understand design implications and don't make critical mistakes, the code continues to evolve. However, in a normal context, what is the ground reality in this context? In a normal day given some significant development goes into product, and when critical change occurs in requirement isn't it a constraint that how much ever we wish, fundamental design aspects cannot be modified? (without throwing away major part of the code). Is it not quite likely that one reaches dead-end on any further possible improvement on design and requirements? I am not advocating any non-Agile practice here, but I want to know from people who practice agile or iterative or evolutionary development methods, as for their real experiences. Have you ever reached such dead-ends? How have you managed to avoid it or escaped it? Or are there measures to ensure that design remains clean and flexible as it evolves?

  • geomipmapping using displacement mapping (and glVertexAttribDivisor)

    - by Will
    I wake up with a clear vision, but sadly my laptop card doesn't do displacement mapping nor glVertexAttribDivisor so I can't test it out; I'm left sharing here: With geomipmapping, the grid at any factor is transposable - if you pass in an offset - say as a uniform - you can reuse the same vertex and index array again and again. If you also pass in the offset into the heightmap as a uniform, the vertex shader can do displacement mapping. If the displacement map is mipmapped, you get the advantages of trilinear filtering for distant maps. And, if the scenery is closer, rather than exposing that the you have a world made out of quads, you can use your transposable grid vertex array and indices to do vertex-shader interpolation (fancy splines) to do super-smooth infinite zoom? So I have some questions: does it work? In theory, in practice? does anyone do it? Does this technique have a name? Papers, demos, anything I can look at? does glVertexAttribDivisor mean that you can have a single glMultiDrawElementsEXT or similar approach to draw all your terrain tiles in one call rather than setting up the uniforms and emitting each tile? Would this offer any noticeable gains? does a heightmap that is GL_LUMINANCE take just one byte per pixel(=vertex)? (On mainstream cards, obviously. Does storage vary in practice?) Does going to the effort of reusing the same vertices and indices mean that you can basically fill the GPU RAM with heightmap and not a lot else, giving you either bigger landscapes or more detailed landscapes/meshes for the same bang? is mipmapping the displacement map going to work? On future cards? Is it going to introduce unsurmountable inaccuracies if it is enabled?

  • Are certain problems solved more elegantly with AOP?

    - by Winston Ewert
    I've come across the idea of Aspect Oriented Programming, and I have some concerns with it. The basic idea seems to be that we want to take cross-cutting concerns which aren't well modularized using object and modularize them. That is all very fine and well. But the implementation of AOP seems to be that of modifying code from outside of the module. So, for example, an aspect could be written that changes what happens when a particular object is passed as a parameter in a function. This seems to go directly against the idea of modules. I should not be able to modify a module's behavior from outside of that module, otherwise the whole point of modules are overturned. But aspects seem to be doing exactly that! Basically, aspects seems to be a form of code patching. It may useful for some quick hacks; but, as a general principle perhaps its not something you want to do. Aspect Oriented Programming seems to me taking a bad practice and raising to a general design principle. Is AOP a good practice? Are certain programming problems solved more elegantly with AOP?
