  • Why do most Database developers hate Agile

    - by Calm Storm
    To me "Agile" methodology is a common-sense oriented approach and one that should likely be adopted for most software projects. I find that while a lot of Middle Tier Developers and Front End developers find it a very sensible project delivery model, plenty of Database developers (and good ones) seem to be totally against it. They are very keen on knowing the biggest picture and designing a database solution that will cater to that. They do not seem to like "Vertical striping" of a functionality. They would rather see the complete design document/feature document instead of concentrating on small user stories. Sarcasm aside, can someone realistically provide some insight as to why this mentality is prevalent? Especially DB devs? What would be a convincing argument against that?

  • JBoss database connection pool configuration

    - by Qben
    I am facing an connection pool issue in my clustered JBoss installation. From time to time one of my connection pools will hit the roof and I get a lot of these in my logfile. java.sql.SQLException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); The odd thing is that I can see in the JMX console that the ConnectionCount hit the roof, but at the same time InUseConnectionCount is often quite small. The problem will resolve itself after a couple of minutes but during recovery phase my application will not work (for obvious reasons). The question is if this indicate an error in the configured timeouts of the connections (I pretty much use defaults), or if my pool is simply too small to handle the peaks. Under normal operation I would say I use ~40% of the configured max number of connections. The reason I just don't increase the max number of connection is that if I actually used up all connections I suspect that InUseConnectionCount would hit the roof. Hence I suspect I might have more issues than just a too small pool size. Maybe InUseConnectionCount has decreased at the time I check jmx-console and it actually do hit the roof? I tend to collect data every second minute. Any hints are more than welcome.

  • what are the limitations of mobile phones and web development

    - by Kieran
    simple really.. I am have been asked to do a mobile site (straight html + css (+ maybe jquery mobile later on)). The site will need to support the new type smart phone and the old type Nokia/(Symbian OS) with the web browser. Doubts and reservations aside as to anyone without a smart phone would bother visiting this site it still needs to support it. My first question is do older phones support PNG images and transparancey... But this has led me to a much broader question of what are some of the limitations of developing for older phone platforms is there anything that has caught mobile web devs out and had them scratching their head for an afternoon.. what are the limitations of mobile phones?

  • Custom object based on database table

    - by Archangel
    Suppose that I have a database query which looks like below - select name, gender, birthday from person where person_id = 1; When this query is executed, some records from the database are returned. I want to make a custom object which will contain the exact attributes as the column names, with the corresponding values. As an example, suppose that the object is X. So it will have three attributes which are X.name, X.gender and X.birthday, with the corresponding values from the records. Is it doable in PHP? If so, then how?

  • Doctrine SQL Server uniqueidentifier isn't cast as char or nvarchar when retrieved from the database

    - by Tres
    When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

  • Best windows iphone app development alternative

    - by Nash0
    What do you think is the best way to develop iphone apps on windows? What are the pros / cons of your method, and why do you use it over other options? How complex is your method in relation to other options? I am more interested in standalone and web apps but fell free to discuss gaming graphics. Yes I know you need to build on a mac to be able to put it on the app store, so no "use a mac" answers please.

  • ajax page works in development (vs2010) but does a full postback on production win2k8R2

    - by merk
    Hi all, I have a stupid simple page. I've got a panel and a button. Clicking the button either hides or displays the panel. That much works. I added in a script manager control and update panel - put all the page contents in the updatepanel/contenttemplate When i run this under vs2010 and click the button, the page does NOT post back - the panel just appears or disappears without the whole page refreshing, which is what i wanted. I upload this to my IIS7.5 server and the page is posting back/whole page is refreshing when i click the button. Do i need to configure anything on the server to enable ajax? thanks

  • Design Solution For Storing-Fetching Images

    - by Chaitanya
    This is a design doubt am facing, I have a collection of 1500 images which are to be displayed on an asp.net page, the images to be displayed differ from one page to another, the count of these images will increase in the time to come, a.) is it a good idea to have the images on the database, but the round trip time to fetch the images from the database might be high. b.) is it good to have all the images on a directory, and have a virtual file system over it, and the application will access the images from the directory Do we have in particular any design strategy in a traditional database for fetching images with the least round trip time, does any solution other than usage of a traditional database exists? ps: I use SQL Server to store these images.

  • As a team should we develop locally and merge into the dev server, or develop on the dev server?

    - by CogitoErgoSum
    Hey, Recently I was tasked with writing up formal procedures for a team based development enviroment. We have several projects with multiple modules each. Right now there are only two programmers, however there are plans to expand to 4-6 programmers. Each programmer will be working on the same project and possibly pages which may cause over writing or error issues. So far the ideal solution I have thought up is: Local development (WAMP/VM or some virtual server instance on their own machine). Once a developer has finished their developments, they check it into the CVS Repository and merge it wih other fixes etc. The CVS version is then deployed to the primary dev server for testing by the devs. The MySQL DAtabases are kept on the primary dev server and users may remotely connect to it. Any Schema / Data alterations are run through a DB Admin who will notify all devs of any DB Changes (Which should be rare). Does anyone see an issue with this or have a better solution?

  • Trying to trigger php script, get EXC_BAD_ACCESS iPhone development

  • "Did you mean" feature on a dictionary database

    - by Hazar
    I have a ~300.000 row table; which includes technical terms; queried using PHP and MySQL + FULLTEXT indexes. But when I searching a wrong typed term; for example "hyperpext"; naturally giving no results. I need to "compansate" little writing errors and getting nearest record from database. How I can accomplish such feaure? I know (actually, learned today) about Levenshtein distance, Soundex and Metaphone algorithms but currently not having a solid idea to implement this to querying against database. Best regards. (Sorry about my poor English, I'm trying to do my best)

  • Is MySQL Replication Appropriate in this case?

    - by MJB
    I have a series of databases, each of which is basically standalone. It initially seemed like I needed a replication solution, but the more I researched it, the more it felt like replication was overkill and not useful anyway. I have not done MySQL replication before, so I have been reading up on the online docs, googling, and searching SO for relevant questions, but I can't find a scenario quite like mine. Here is a brief description of my issue: The various databases almost never have a live connection to each other. They need to be able to "sync" by copying files to a thumb drive and then moving them to the proper destination. It is OK for the data to not match exactly, but they should have the same parent-child relationships. That is, if a generated key differs between databases, no big deal. But the visible data must match. Timing is not critical. Updates can be done a week later, or even a month later, as long as they are done eventually. Updates cannot be guaranteed to be in the proper order, or in any order for that matter. They will be in order from each database; just not between databases. Rather than a set of master-slave relationships, it is more like a central database (R/W) and multiple remote databases (also R/W). I won't know how many remote databases I have until they are created. And the central DB won't know that a database exists until data arrives from it. (To me, this implies I cannot use the method of giving each its own unique identity range to guarantee uniqueness in the central database.) It appears to me that the bottom line is that I don't want "replication" so much as I want "awareness". I want the central database to know what happened in the remote databases, but there is no time requirement. I want the remote databases to be aware of the central database, but they don't need to know about each other. WTH is my question? It is this: Does this scenario sound like any of the typical replication scenarios, or does it sound like I have to roll my own? Perhaps #7 above is the only one that matters, and given that requirement, out-of-the-box replication is impossible. EDIT: I realize that this question might be more suited to ServerFault. I also searched there and found no answers to my questions. And based on the replication questions I did find both on SO and SF, it seemed that the decision was 50-50 over where to put my question. Sorry if I guessed wrong.

  • When to use @Singleton in a Jersey resource

    - by dexter
    I have a Jersey resource that access the database. Basically it opens a database connection in the initialization of the resource. Performs queries on the resource's methods. I have observed that when I do not use @Singleton, the database is being open at each request. And we know opening a connection is really expensive right? So my question is, should I specify that the resource be singleton or is it really better to keep it at per request especially when the resource is connecting to the database? My resource code looks like this: //Use @Singleton here or not? @Path(/myservice/) public class MyResource { private ResponseGenerator responser; private Log logger = LogFactory.getLog(MyResource.class); public MyResource() { responser = new ResponseGenerator(); } @GET @Path("/clients") public String getClients() { logger.info("GETTING LIST OF CLIENTS"); return responser.returnClients(); } ... // some more methods ... } And I connect to the database using a code similar to this: public class ResponseGenerator { private Connection conn; private PreparedStatement prepStmt; private ResultSet rs; public ResponseGenerator(){ Class.forName("org.h2.Driver"); conn = DriverManager.getConnection("jdbc:h2:testdb"); } public String returnClients(){ String result; try{ prepStmt = conn.prepareStatement("SELECT * FROM hosts"); rs = prepStmt.executeQuery(); ... //do some processing here ... } catch (SQLException se){ logger.warn("Some message"); } finally { rs.close(); prepStmt.close(); // should I also close the connection here (in every method) if I stick to per request // and add getting of connection at the start of every method // conn.close(); } return result } ... // some more methods ... } Some comments on best practices for the code will also be helpful.

  • Accessing global variables within functions in PHP

    - by st3
    There are multiple times in one page where I need to connect and subsequently query a MySQL database, yet my code won't let me. I think it might be something to do with how my files are nested but it makes no sense. I am opening the SQL connection in the header file. The top of the offending page looks like the following: <?php $page_title = 'Dashboard'; include('templates/header.inc'); // includes a 'require_once('mysqli_connect.php') and a small query to the database; require_once('includes/functions.php'); require_once('includes/dashboard_sql.php'); // Contains functions which connect to database (which are failing.) ?> I get the PHP error Notice: Undefined variable: dbc in /Library/WebServer/Documents/pediatory_site/includes/dashboard_sql.php Where $dbc is the database connection defined in mysqli_connect.php. If anyone could help me out that would be great.

  • Web-Application development startup advice

    - by rpr
    Dear programmers of StackOverflow, recently me and two of my friends from college started a software company. We are developing web-applications using GWT-Spring-Hibernate and other helper frameworks. In a couple of months, we managed to set up a stable back-end and produced some demo programs for CRM solutions. Our area of interest is CRM where we can combine the flexibility of our back-end with the slick looking GWT based GUIs. Unfortunately we live in a third world country (well, kind of two and a half :) and no one here gives our work enough credit, or really cares about the advantages of web-apps. We are stuck at the moment because our current clients do not want to pay that much money for just "putting their local app on the web". Since we can not find satisfying work here, we have decided to work online/international. I was wondering if you guys know a good freelance kind of sites where we can throw ourselves into the market.. Also a question from frustration, to those who are in the field or knowledgeable/interested about web based CRM, how much would you ask/pay for lets say a web app which will keep track of all the patients of a multi-branch clinic also allowing the patients to access to view their own records? Including tiered authorization, logging etc.. Many thanks in advance for your responses!

  • sqlite3.OperationalError: database is locked - non-threaded application

    - by James C
    Hi, I have a Python application which throws the standard sqlite3.OperationalError: database is locked error. I have looked around the internet and could not find any solution which worked (please note that there is no multiprocesses/threading going on, and as you can see I have tried raising the timeout parameter). The sqlite file is stored on the local hard drive. The following function is one of many which accesses the sqlite database, and runs fine the first time it is called, but throws the above error the second time it is called (it is called as part of a for loop in another function): def update_index(filepath): path = get_setting('Local', 'web') stat = os.stat(filepath) modified = stat.st_mtime index_file = get_setting('Local', 'index') connection = sqlite3.connect(index_file, 30) cursor = connection.cursor() head, tail = os.path.split(filepath) cursor.execute('UPDATE hwlive SET date=? WHERE path=? AND name=?;', (modified, head, tail)) connection.commit() connection.close() Many thanks.
