• Oracle: delete suddenly taking a long time

  - by Damo

  Hi We have a feed process which runs every day of the year. As part of that we delete every row from a table (approx 1 million rows) every day, repopulate it using 5 different stored procedures and then commit the transaction. This is the only commit statement that we call. All of a sudden the delete has started takign about 2 hours to complete. The delete is also very simple (delete from T_PROFILE_WORK) This has worked perfectly well for the past year, but in the past week i have noticed this issue. Any help on this is greatly appreciated Thanks Damien

• What is the best way to pass server side variables to JavaScript on the client side?

  - by steve_c

  Our application uses a lot of configuration options. Those options need to be reflected on the client side in the form of User preferences, site wide preferences, etc. Currently, we pass server side settings down to the client side in the form of JSON that is stored in custom attributes in the markup for a specific element (and no, our application currently doesn't worry about W3C validation). We then retrieve the data from the custom attribute, and parse it into a JSON object for use in script using jQuery. One drawback to this is referencing attributes on elements from within event handlers. I know this is frowned upon, as it can create circular references, and subsequently memory leaks. I would much prefer to use jQuery's data function, but you can't invoke this from the server side at page render time. What does everyone else do in this type of scenario?

• jQuery plugin call internal function

  - by pbcoder

  I want to call removeSomething() (see in line 9) internally: JS-Code is: (function($){ $.fn.extend({ Engine: function(options) { var defaults = { ... }; var options = $.extend(defaults, options); removeSomething(); //----------------------------------------------------------------------- //Public Functions ------------------------------------------------------ //----------------------------------------------------------------------- this.removeSomething = function() { ... }; } }); })(jQuery); But if I call removeSomething console outputs that removeSomething is not a function, how do I have to call this function? The function should be available internally and externally. Thanks for help!

• Parsing plain data with Javascript (JQuery)

  - by Angelus

  Well , I have this text in a Javascript Var: GIMP Palette Name: Named Colors Columns: 16 # 255 250 250 snow (255 250 250) 248 248 255 ghost white (248 248 255) 245 245 245 white smoke (245 245 245) 220 220 220 gainsboro (220 220 220) 255 250 240 floral white (255 250 240) 253 245 230 old lace (253 245 230) 250 240 230 linen (250 240 230) 250 235 215 antique white (250 235 215) 255 239 213 papaya whip (255 239 213) And What I need is to cut it in lines and put them in one Array , after that i must separate each number and the rest in an string. I'm getting crazy searching functions to do that but now i can't see anyone in Javascript. modified End expected format will be first the next: array[0]='255 250 250 snow (255 250 250)' Then i wanna take it and extract each line into some vars to use them: colour[0]=255; colour[1]=250; colour[2]=250; string=snow (255 250 250); (the vars will be reused with each line)

• Windows Mobile 6.x How to explicitly lock the app in one orientation?

  - by Stuart

  I'm trying to get an app on the WinMo App Store. As part of this, Microsoft App's Store has asked that I need to support landscape as well as portrait. What they've said is OK is: If dynamic switching is implicitly allowed, the app will be tested just as if it supports both portrait and landscape even if only a portrait or landscape resolution is checked. You may explicitly lock the app in one orientation (which means portrait mode if the app does not handle landscape mode functions), provided the default OS orientation is preserved once the app exits. I'd love to do answer 2 - but I can't find any way of doing it - and they won't provide me any other clues - they suggested I ask on the forums... so here I am on Stack Overflow - far better than on the forums :) Anyone got any suggestions?

• Send custom data when initializing java WebService over soap

  - by Mesni

  Hello. I have a question about sending additional data over soap to the functions. My webService function requests only one integer, for example an getDocumentPrivilage(DocumentID). In another WebService user registered and he got an unique ID, so the other application can see who he is. So on Service one he registers, gets id and it has to send it to the other webservice tor the privilage. Id dont wish to rewrite the function so that it gets the unique ID (like this getDocumentPrivilage(uniqID,DocumentID)) but, the wish is that i would be able to create a client that sends this data at the initialization or somehow as some sort of parameter behind the function. Is this possible?? I tried the ServiceLifecycle but cant see any setting i've given in. Im using WebSphere CE for the server and Jax-ws Creating the webapp in java. Thank you very much in advance. lp, Mesni

• Best way to handle MySQL date for performance with thousands of users

  - by bitLost

  I am currently part of a team designing a site that will potentially have thousands of users who will be doing a number of date related searches. During the design phase we have been trying to determine which makes more sense for performance optimization. Should we store the datetime field as a mysql datetime. Or should be break it up into a number of fields (year, month, day, hour, minute, ...) The question is with a large data set and a potentially large set of users, would we gain performance wise breaking the datetime into multiple fields and saving on relying on mysql date functions? Or is mysql already optimized for this?

• How to get array keys in Javascript?

  - by DisgruntledGoat

  I have an array created with this code: var widthRange = new Array(); widthRange[46] = { sel:46, min:0, max:52 }; widthRange[66] = { sel:66, min:52, max:70 }; widthRange[90] = { sel:90, min:70, max:94 }; I want to get each of the values 46, 66, 90 in a loop. I tried for (var key in widthRange) but this gives me a whole bunch of extra properties (I assume they are functions on the object). I can't use a regular for loop since the values are not sequential.

• STL deque accessing by index is O(1)?

  - by jasonline

  I've read that accessing elements by position index can be done in constant time in a STL deque. As far as I know, elements in a deque may be stored in several non-contiguous locations, eliminating safe access through pointer arithmetic. For example: abc-defghi-jkl-mnop The elements of the deque above consists of a single character. The set of characters in one group indicate it is allocated in contiguous memory (e.g. abc is in a single block of memory, defhi is located in another block of memory, etc.). Can anyone explain how accessing by position index can be done in constant time, especially if the element to be accessed is in the second block? Or does a deque have a pointer to the group of blocks? Update: Or is there any other common implementation for a deque?

• amp is included in url struts tag

  - by lakshmanan

  Hi, In my web application, I use strust2 url tag to pass parameters like id etc., For example, I use a link to delete an entity and I use param to pass the id of the entity to be deleted. And I follow this throughout my web app for adding, editing, deleting an entity. During run time, sometimes, I don't get the params to be stored in my action's bean properties. When I see the link that is generated, I get something like <a href='/projit1/p/discuss/viewDiscussion.action?d=11&amp;amp;amp;projid=11&amp;amp;disid=4'> What are these amps for ? why do they sit in between the action calls (made by link via url tag actions ) ? By the time I traverse back and forth in my web app, I get 10s and 20s of amp sitting in the request URL. What is the problem here ? Please help.

• StreamWriter does throw exception underlying connection is broken?

  - by Jane

  I am using StreamWriter instantiated over a Tcpstream like this streamWriter = new StreamWriter(tcpClient.GetStream()); I am confused about the behaviour of following calls with regards to Exceptions. The following two functions are expected to raise IOException , Surprisingly they do not raise the IOException when the server is to which the tcpClient is connected is disconnected and therefore the underlying TCP client connection is broken.. These two lines execute without raising any Exception. Why ? streamWriter.WriteLine(strBuffer); streamWriter.Flush();

• Java or Python distributed compute job (on a student budget)?

  - by midget_sadhu

  I have a large dataset (c. 40G) that I want to use for some NLP (largely embarrassingly parallel) over a couple of computers in the lab, to which i do not have root access, and only 1G of user space. I experimented with hadoop, but of course this was dead in the water-- the data is stored on an external usb hard drive, and i cant load it on to the dfs because of the 1G user space cap. I have been looking into a couple of python based options (as I'd rather use NLTK instead of Java's lingpipe if I can help it), and it seems distributed compute options look like: Ipython DISCO After my hadoop experience, i am trying to make sure i try and make an informed choice -- any help on what might be more appropriate would be greatly appreciated. Amazon's EC2 etc not really an option, as i have next to no budget.

• How does a Java Arraylist contains() method evaluate objects?

  - by mvid

  Say i create one object and add it to my ArrayList. If I then create another object with exactly the same constructor input, will the contain() method evaluate the two objects to be the same? Assume the constructor doesn't do anything funny with the input, and the variables stored in both objects are identical. ArrayList<Thing> basket = new ArrayList<Thing>(); Thing thing = new Thing(100); basket.add(thing); Thing another = new Thing(100); basket.contains(another); // true or false?

• Read and write .NET Objects in SQL Database without serialization.

  - by Mohit

  Hello, I have a small query. I need to create a Caching Service of my own that will write and read .NET Objects to and from the Database. Now, I have achieved that with the help of Binary Serialization. But the Problem is I need to deliberately marked my objects as [Serializable], which makes me think that what if someone will try to add an object which is not marked as [Serializable]. Thus, I need to find a way to read and write Objects to Database without Serialization. I have one thought too.. As we all know Session can store any object in it. Now, we can make sessions to be stored in the DB, outproc. What mechanism it uses to store these objects without serializing or deserializing. Any help will be highly appreciated. Thanks. M.B

• Controlling a browser from Python

  - by Noio

  I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

• Defining multiple VBA objects within one function or sub-routine?

  - by Harokitty

  I have the following VBA code: Option Explicit Private a(2) as Double Private b(2) as Double Public Function Hello(X1 As Double, X2 As Double) As Double a(1) = X1 + X2 a(2) = X1/X2 b(1) = X1 b(2) = X2^2 Hello = a(1)+a(2)+b(1)+b(2) End Function Within the function Hello I have defined a(1),a(2),b(1),b(2). However, I want to make some function or sub-routine that accepts X1 and X2 as arguments and spits out the values for a(1),a(2),b(1),b(2). This is because I use the above definitions for a(1),a(2),b(1),b(2) in about 20 functions in my module and would like to avoid having to do the following in each function that I use thesis in: a(1) = X1 + X2 a(2) = X1/X2 b(1) = X1 b(2) = X2^2

• PHP upload to GoDaddy hosted site

  - by 105894384987190582154

  Hi, relatively new to both hosting and PHP, so apologies for (probably) missing the obvious, but… I built a page which would allow file uploads to my site, following the example laid out here: W3Schools PHP upload exercise Through the File Manage on my Godaddy hosting, I created a folder named ’upload’ so that the file would land there after being uploaded through the page I had built. Part of the returned page that appears after submitted the file reads: Temp file: d:temptmpphpE4C9.tmp Stored in: upload/testfile.txt which would indicate that the file has been sucesscully uploaded given the code in the example. However, I cannot see the file in the ’upload’ folder via my File Manage, or anywhere else on the hosting of my site (as far as I can see). I also cannot see the ’temp’ folder anywhere either… Any help or clarification would be greatly appreciated. Thanks Tim

• What are some ways to identify a logged in user on the web?

  - by farinspace

  Here is the scenario: There are 5 websites (different domain names) that need to share a session. I am using a bit of code on each site which returns a "blank.gif" image and at the same time sets the session (syncing it up to the current session). Each of the sites calls a session-img from each of the other sites. Also, all sites have access to the same database (where the session is stored). This works great on FF and Chrome, but not on IE (or Safari PC)... I need to come up with an alternative method to keep a session active? The app is a small custom CMS, so really only 2-3 people will be using it. I can probably identify user logins by IP and then continue to check for the IP accross all sites... Is there something more granular such as a computer uuid that i can check for?

• biginteger calculation problem

  - by murali

  I am using the following code but the parameters are not passed to the methods. BigInteger p = BigInteger.valueOf(0); BigInteger u1 = obj.bigi_calc(g1, l); In this g1,l are long values. The method is private BigInteger bigi_calc(long g1, long l){ BigInteger cal = BigInteger.valueOf(g1); BigInteger cal1= BigInteger.valueOf(l); for(BigInteger f = BigInteger.ONE;f.compareTo(cal1)>0;f=f.add(BigInteger.ONE)){ //BigInteger p= BigInteger.valueOf(0); p = cal.multiply(cal1); System.out.println("check p"+p); } // System.out.println("check p"+p); return p; } The elipse shows that it may be out of sync, but the parameters are not passed to the functions. Can you please help me to solve this problem?

• jquery toggle+paginate+multiple instances

  - by mark

  Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

• How do I choose a database?

  - by liamzebedee

  I need a comparison table of some sort for database varieties (MySQL, SQLite etc.). I can't find one. My use case is, I am implementing storage of objects in a distributed hash table. I need a database solution that is: Fast for sorting Simplistic (no users, preferably no additional structures like multiple tables etc.) Concurrent (if possible) Multi-platform File based (not stored in memory primarily) Centralized I will be programming in Go. As I understand, I believe I need what is called a Document Orientated Database, because I am storing objects, identified by keys. EDIT: While I am implementing a DHT, I will also be storing metadata about the objects, such as access counts etc. It would also be preferable to have TLL (time to live)

• OO C++ - Virtual Methods

  - by Phorce

  Just a really quick question here. I'm using virtual functions to read in from a text file. Now, it's virtual because in one aspect I want the values to be normalised, and, in the other respect I don't want them to be normalised. I have tried to do this: bool readwav(string theFile, 'native'); So in theory, if the 'native' is used, this method should be called, however, if 'double' is called then a different version of the method is called. Same for if the value is empty, it should just perform the native option. First question, why doesn't the declaration above work? Also, is this the best route to go down? Or, would it be better to have just one class method that switches between the options. Thanks :)
