  • how to read a User uploaded file, without saving it to the database

    - by GoodGets
    I'd like to be able to read an XML file uploaded by the user (less than 100kb), but not have to first save that file to the database. I don't need that file past the current action (its contents get parsed and added to the database; however, parsing the file is not the problem). Since local files can be read with: File.read("export.opml") I thought about just creating a file_field for :uploaded_file, then trying to read it with File.read(params[:uploaded_file]) but all that does is throw a TypeError (can't convert HashWithIndifferentAccess into String). I really have tried a lot of various things (including reading from the /tmp directory as well), but could get none of them to work. I hope the brevity of my question doesn't mask the effort I've given to try to solve this on my own, but I didn't want to pollute this question with a hundred ways of how NOT to get it done. Big thanks to anyone who chimes in.

  • SUnreclaim size increasing in syc with a TCP-CLOSE_WAIT till application restart

    - by maver1k
    Recently found a behaviour where my application had a connection in TCP Close_wait state till the app was restarted (after about 5 hours). But during this period the SUnreclaim space was also increasing constantly and went down on restart. The application is runnning on a rhel5 os and Im not very familiar with the memory management system. Would appreciate if someone clould tell me what extactly is the Ureclaim space and why it is increasing in sync with the close_wait. Thanks.

  • Populate JSP dropdown with database info

    - by Cano63
    I'm looking for the way to populate a JSP dropdown. I want that when the JSP loads it fills the dropdown with the info that I have in a database table. I'm including the code of my class that will create the array and fill it with the database info. What I don't know is how to call that class from my JSP and fill the dropdown. // this will create my array public static ArrayList<DropDownBrands> getBrandsMakes() { ArrayList<DropDownBrands> arrayBrandsMake = new ArrayList<DropDownBrands>(); while (rs.next()) { arrayBrandsMake.add(loadOB(rs)); // CARGO MI ARREGLO CON UN OBJETO } return arrayBrandsMake; } // this will load my array object private static DropDownBrands loadOB(ResultSet rs) throws SQLException { DropDownBrands OB = new DropDownBrands(); OB.setBrands("BRAN"); return OB; }

  • Problems installing sql management studio express on win7-64

    - by P a u l
    Here's what happened: install sql express 2008 install sql 2008 sp1 download and install SSMSE x64. There is a popup re incompatibility with the OS, and the help takes you back to the sp1 download page. It won't install... in fact the install that comes up appears to be for sql server express and I see no mention of SSMSE anywhere in the tangle of dialogs. There appears to be no version of SSMSE for Win7-64 at this time. Do you know any way to fix this?

  • ASP.NET - dynamically creating database connection in datasets

    - by Foo
    I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects. Any ideas?

  • Problem with ColdFusion communicating with MySQL database

    - by Greg
    Hi, I have been working to migrate a non-profit website from a local server (running Windows XP) to a GoDaddy hosting account (running Linux). Most of the pages are written in ColdFusion. Things have gone smoothly, up until this point. There is a flash form within the site (see this page: http://www.preservenet.cornell.edu/employ/submitjob.cfm) which, when completed, takes the visitor to this page: submitjobaction.cfm . I'm not quite sure what to make of this error, since I copied exactly what had been in the old MySQL database, and the .cfm files are exactly as they had been when they worked on the old server. Am I missing something? Below is the code from the database that the error seems to be referring to. When I change "Positionlat" to some default value in the database as it suggests in the error, it says that another field needs a default value, and it's a neverending chain of errors as I try to correct it. This is probably a stupid error that I'm missing, but I've been working at it for days and can't find what I'm missing. I would really appreciate any help. Thanks! -Greg DROP TABLE IF EXISTS employopp; CREATE TABLE employopp ( POSTID int(10) NOT NULL auto_increment, USERID varchar(10) collate latin1_general_ci default NULL, STATUS varchar(10) collate latin1_general_ci NOT NULL default 'ACTIVE', TYPE varchar(50) collate latin1_general_ci default 'professional', JOBTITLE varchar(70) collate latin1_general_ci default NULL, NUMBER varchar(30) collate latin1_general_ci default NULL, SALARY varchar(40) collate latin1_general_ci default NULL, ORGNAME varchar(70) collate latin1_general_ci default NULL, DEPTNAME varchar(70) collate latin1_general_ci default NULL, ORGDETAILS mediumtext character set utf8 collate utf8_unicode_ci, ORGWEBSITE varchar(200) collate latin1_general_ci default NULL, ADDRESS varchar(60) collate latin1_general_ci default 'none given', ADDRESS2 varchar(60) collate latin1_general_ci default NULL, CITY varchar(30) collate latin1_general_ci default NULL, STATE varchar(30) collate latin1_general_ci default NULL, COUNTRY varchar(3) collate latin1_general_ci default 'USA', POSTALCODE varchar(10) collate latin1_general_ci default NULL, EMAIL varchar(75) collate latin1_general_ci default NULL, NOMAIL varchar(5) collate latin1_general_ci default NULL, PHONE varchar(20) collate latin1_general_ci default NULL, FAX varchar(20) collate latin1_general_ci default NULL, WEBSITE varchar(200) collate latin1_general_ci default NULL, POSTDATE varchar(10) collate latin1_general_ci default NULL, POSTUNTIL varchar(20) collate latin1_general_ci default 'select date', POSTUNTILFILLED varchar(20) collate latin1_general_ci NOT NULL default 'until filled', texteHTML mediumtext character set utf8 collate utf8_unicode_ci, HOWTOAPPLY mediumtext character set utf8 collate utf8_unicode_ci, CONFIRSTNM varchar(30) collate latin1_general_ci default NULL, CONLASTNM varchar(60) collate latin1_general_ci default NULL, POSITIONCITY varchar(30) collate latin1_general_ci default NULL, POSITIONSTATE varchar(30) collate latin1_general_ci default NULL, POSITIONCOUNTRY varchar(3) collate latin1_general_ci default 'USA', POSITIONLAT varchar(50) collate latin1_general_ci NOT NULL, POSITIONLNG varchar(50) collate latin1_general_ci NOT NULL, PRIMARY KEY (POSTID) ) ENGINE=MyISAM AUTO_INCREMENT=2007 DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;

  • OpenGL/Carbon/Cocoa Memory Management Autorelease issue

    - by Stephen Furlani
    Hoooboy, I've got another doozy of a memory problem. I'm creating a Carbon (AGL) Window, in C++ and it's telling me that I'm autorelease-ing it without a pool in place. uh... what? I thought Carbon existed outside of the NSAutoreleasePool... When I call glEnable(GL_TEXTURE_2D) to do some stuff, it gives me a EXC_BAD_ACCESS warning - but if the AGL Window is never getting release'd, then shouldn't it exist? Setting set objc-non-blocking-mode at (gdb) doesn't make the problem go away. So I guess my question is WHAT IS UP WITH CARBON/COCOA/NSAutoreleasePool? And... are there any resources for Objective-C++? Because crap like this keeps happening to me. Thanks, -Stephen --- CODE --- Test Draw Function void Channel::frameDraw( const uint32_t frameID) { eq::Channel::frameDraw( frameID ); getWindow()->makeCurrent(false); glEnable(GL_TEXTURE_2D); // Throws Error Here } Make Current (Equalizer API from Eyescale) void Window::makeCurrent( const bool useCache ) const { if( useCache && getPipe()->isCurrent( this )) return; _osWindow->makeCurrent(); } void AGLWindow::makeCurrent() const { aglSetCurrentContext( _aglContext ); AGLWindowIF::makeCurrent(); if( _aglContext ) { EQ_GL_ERROR( "After aglSetCurrentContext" ); } } _aglContext is a valid memory location (i.e. not NULL) when I step through. -S!

  • Database Instance

    - by Sam
    I read a statement from an exercise: construct a database instance which conforms to diagram 1 but not to diagram 2. The diagrams are different n-ary relationships that have different relationships. Diagram 1 has a many to one to many to one relationship. Diagram 2 has many to many to many to one relationship. So, to really understand this problem, what does a database instance mean? Is it to make an example or abstract entities like a1, a2, or a3. Thanks for your time.

  • VS 2010 Server Explorer Database Showing No Tables

    - by Andy
    I'm working on a .Net application that needs to read from an Oracle 10g database behind Siebel. In VS 2010 Server Explorer, I've created a connection using the OracleClient type connector with a reference to the Oracle TNS service name as the "server name." The "Test Connection" button shows that the connection is successful. However, in the Server Explorer, when I go to expand the Tables, no tables are shown. I know for a fact that there are 3000+ tables in the database (thanks Siebel). Anyone know what's happening here? I'd like to create an Entity Framework 4.0 Entity Data Model... Thanks for the help!

  • Wisdom of merging 100s of Oracle instances into one instance

    - by hoytster
    Our application runs on the web, is mostly an inquiry tool, does some transactions. We host the Oracle database. The app has always had a different instance of Oracle for each customer. A customer is a company which pays us to provide our service to the company's employees, typically 10,000-25,000 employees per customer. We do a major release every few years, and migrating to that new release is challenging: we might have a team at the customer site for a couple weeks, explaining new functionality and setting up the driving data to suit that customer. We're considering going multi-client, putting all our customers into a single shared Oracle 11g instance on a big honkin' Windows Server 2008 server -- in order to reduce costs. I'm wondering if that's advisable. There are some advantages to having separate instances for each customer. Tell me if these are bogus, please. In my rough guess about decreasing importance: Our customers MyCorp and YourCo can be migrated separately when breaking changes are made to the schema. (With multi-client, we'd be migrating 300+ customers overnight!?!) MyCorp's data can be easily backed up and (!!!) restored, without affecting other customers. MyCorp's data is securely separated from their competitor YourCo's data, without depending on developers to get the code right and/or DBAs getting the configuration right. Performance is better because the database is smaller (5,000 vs 2,000,000 rows in ~50 tables). If MyCorp's offices are (mostly) in just one region, then the MyCorp's instance can be geographically co-located there, so network lag doesn't hurt performance. We can provide better service to global clients, for the same reason. In MyCorp wants to take their database in-house, then we can easily export their instance, to get MyCorp their data. Load-balancing is easier because instances can be placed on different servers (this is with a web farm). When a DEV or QA instance is needed, it's easier to clone the real instance and anonymize the data, because there's much less data. Because they're small enough, developers can have their own instance running locally, so they can work on code while waiting at the airport and while in-flight, without fighting VPN hassles. Q1: What are other advantages of separate instances? We are contemplating changing the database schema and merging all of our customers into one Oracle instance, running on one hefty server. Here are advantages of the multi-client instance approach, most important first (my WAG). Please snipe if these are bogus: Less work for the DBAs, since they only need to maintain one instance instead of hundreds. Less DBA work translates to cheaper, our main motive for this change. With just one instance, the DBAs can do a better job of optimizing performance. They'll have time to add appropriate indexes and review our SQL. It will be easier for developers to debug & enhance the application, because there is only one schema and one app (there might be dozens of schema versions if there are hundreds of instances, with a different version of the app for each version of the schema). This reduces costs too. The alternative is having to start every debug session with (1) What version is this customer running and (2) Let's struggle to recreate the corresponding development environment, code and database. (We need a Virtual Machine that includes the code AND database instance for each patch and release!) Licensing Oracle is cheaper because it's priced per server irrespective of heft (or something -- I don't know anything about the subject). The database becomes a viable persistent store for web session data, because there is just one instance. Some database operations are easier with one multi-client instance, like finding a participant when they're hazy about which customer they (or their spouse, maybe) works for: all the names are in one table. Reporting across customers is straightforward. Q2: What are other advantages of having multiple clients in one instance? Q3: Which approach do you think is better (why)? Instance per customer, or all customers in one instance? I'm concerned that having one multi-client instance makes migration near-impossible, and that's a deal killer... ... unless there is a compromise solution like having two multi-client instances, the old and the new. In that case case, we would design cross-instance solutions for finding participants, reporting, etc. so customers could go from one multi-client instance to the next without anything breaking. THANKS SO MUCH for your collective advice! This issue is beyond me -- but not beyond the collective you. :) Hoytster

  • How to recreate missing Team Foundation Server database?

    - by Amadiere
    I've been trying out TFS 2010 Beta 2 on my local machine, or at least, had installed ready to do so. I had some issues with my MSSQL2008 server so I completely uninstalled and re-installed it and that sorted it. However, I'm now in limbo with TFS. I have the software installed, but it has none of the SQL databases installed that go with it. I had no data and am not precious about how to go about it. I figure completely uninstalling and re-installing might be an idea and will most likely fix it (repair didn't work). Is there a quicker way? Is there a command line utility that I can run, or a SQL script to recreate it all?

  • jQuery - Image management

    - by kape123
    Is there a jQuery plug-in / JavaScript control that will allow me to display array of images, but with (at least) option to delete image on certain user action. Something like this: http://www.gmarwaha.com/jquery/jcarousellite/index.php but with dedicated delete button on every image. First extra option that I can think of is to rearrange order of images. If not... I guess I'll start extending mentioned jcarousellite myself....

  • Developer workload management software: recommendations?

    - by PaddyC
    In my place, we use two issue tracking tools, one for production bugs, and another for issues on projects in development. These tools are good for managers. However, at an individual level, other work can also arrive through desk visits, email, or the phone, and those allocating the work aren't always interested in issue tracking systems. I've recently rolled off an 18-month project where I got into a cycle of overtime, and I found that I didn't always have good visibility of all work assigned to me. As a result, I was always very busy, and felt constantly laden down with work, but didn't have the clear data to show my manager (or, ironically, the time to stop and gather the information!). A handwritten list, updated at the end of each day, is a good start, but can anyone recommend better tools to help me get a clear view of my own workload? Ideally, I'm thinking of software tools for developers, which could incorporate estimates, but all suggestions welcome. Thanks, Paddy

  • How to restore PostgreSQL database from .tar file?

    - by Stephen
    I have all PostgreSQL databases backed up during incremental backups using WHM, which creates a $dbName.tar file. Data is stored in these .tar files, but I do not know how to restore it back into the individual databases via SSH. In particular the file location. I have been using: pg_restore -d client03 /backup/cpbackup/daily/client03/psql/client03.tar which generates the error 'could not open input file: Permission denied' Any assistance appreciated.

  • Instance management with Dependency injection (DI)

    - by Sven
    Hello I'm trying to understand how DI exactly works. I'm currently using Windsor as DI container. I use this to load my services dynamically in code without direct reference. But I have change behaviour and want to know a bit more on the instance mgmt using DI. I have a web app projct, here is a WCF service using PerCall as instancemode. This means, new instance/call. In this WCF I call a service (loaded via DI) and this service calls another service (again loaded via DI). The WCF is a new instance in the appdomain, but what about the services. They are also new instances? Is this DI container shared among all WCF instances and are the services in this container also single instances? Can anyone clarify?

  • Storing date and time as epoch vs native datetime format in the database

    - by zakovyrya
    For most of my tasks I find it much easier to work with date and time in the epoch format: it's trivial to calculate timespan or determine if some event happened before or after another, I don't have to deal with time-zone issues if the data comes from different geographical sources, in case of scripting languages what I usually get from database when I request a datetime-typed column is a string that I need to parse in order to work with it. This list can go on, but for me in order to keep my code portable that's enough to ditch database's native datetime format and store date and time as integer. What do you guys think?

  • database security with php page that spits out XML

    - by Rees
    Hello, I just created a PHP page that spits outs some data from my database in an XML format. This data is fetched from a flex application I made. I had spent a long time formatting my tables and database information and do not want anyone to be able to simply type www.mysite.com/page_that_spits_out_XML.php and steal my data. However, at the same time I need to be able to access this page from my flex application. Is there a way I can prevent other people from doing this? Thank you!

  • Normalization in plain English

    - by Yada
    I sort of understand the concept of database normalization but always have a hard time explaining it in plain English especially for a job interview. I have read the wikipedia post, but still find it hard to explain the concept to none developers. "Design a database in a way not to get duplicated data" is the first thing that comes to mind. Does anyone was a nice way to explain the concept of database normalization in plain English. And what are some nice examples to show the differences between first, second and third normal forms. Say you go to a job interview and the person asks: Explain the concept of normalization and how would go about designing a normalized database. What key points are the interviewer looking for?
