  • How to set WCF threads to schedual differently

    - by Gilad
    Hi, I'm running a winservice that has 2 main objectives. Execute/Handle exposed webmethods. Run Inner processes that consume allot of CPU. The problem is that when I execute many inner processes |(as tasks) that are queued to the threadpool or taskpool, the execution of the webmethods takes much more time as WCF also queues its executions to the same threadpool. This even happens when setting the inner processes task priority to lowest and setting the webmethods thread priority to heights. I hoped that Framework 4.0 would improve this, and they have, but still it takes quite allot of time for the system to handle the WCF queued tasks if the CPU is handling other inner tasks. Is it possible to change the Threadpool that WCF uses to a different one? Is it possible to manually change the task queue (global task queue, local task queue). Is it possible to manually handle 2 task queues that behave differently ? Any help in the subject would be appropriated. Gilad.

  • (Oracle Performance) Will a query based on a view limit the view using the where clause?

    - by BestPractices
    In Oracle (10g), when I use a View (not Materialized View), does Oracle take into account the where clause when it executes the view? Let's say I have: MY_VIEW = SELECT * FROM PERSON P, ORDERS O WHERE P.P_ID = O.P_ID And I then execute the following: SELECT * FROM MY_VIEW WHERE MY_VIEW.P_ID = '1234' When this executes, does oracle first execute the query for the view and THEN filter it based on my where clause (where MY_VIEW.P_ID = '1234') or does it do this filtering as part of the execution of the view? If it does not do the latter, and P_ID had an index, would I also lose out on the indexing capability since Oracle would be executing my query against the view which doesn't have the index rather than the base table which has the index?

  • No Hibernate Session bound to thread grails

    - by naresh
    Actually we've lot of quartz jobs in our application. For some time all of the jobs work fine. After some time all jobs are throwing the following exception. org.quartz.JobExecutionException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here [See nested exception: java.lang.IllegalStateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here] at grails.plugins.quartz.QuartzDisplayJob.execute(QuartzDisplayJob.groovy:37) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:573) Caused by: java.lang.IllegalStateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here at grails.plugins.quartz.QuartzDisplayJob.execute(QuartzDisplayJob.groovy:29) ... 2 more

  • SqlCeResultSet re-use

    - by pdiddy
    Can I reuse an existing result set to filter? Lets say I have a result set that contains all data. Then I want to filter that resultset. Can I just execute the sqlcommand on the same resultset? I tried and it didn't seem to work. Does someone know the reason? So the only way to make it work was to create a new resultset and execute the command on that one. So this way I'm always creating a new resulset, can this have some issue?

  • EXC_BAD_ACCESS signal received

    - by Hector Ramos
    When deploying the application to the device, the program will quit after a few cycles with the following error: Program received signal: "EXC_BAD_ACCESS". The program runs without any issue on the iPhone simulator, it will also debug and run as long as I step through the instructions one at a time. As soon as I let it run again, I will hit the EXC_BAD_ACCESS signal. In this particular case, it happened to be an error in the accelerometer code. It would not execute within the simulator, which is why it did not throw any errors. However, it would execute once deployed to the device. Most of the answers to this question deal with the general EXC_BAD_ACCESS error, so I will leave this open as a catch-all for the dreaded Bad Access error. EXC_BAD_ACCESS is typically thrown as the result of an illegal memory access. You can find more information in the answers below. Have you encountered the EXC_BAD_ACCESS signal before, and how did you deal with it?

  • How to fill a webdynpro table binded to a BAPI initially?

    - by Philipp Andre
    Hello SAP-Gurus, im fairly new to webdynpro abap and have the following problem: I created a service returning a set of all existing customers. This function works well, if i test it in a litte program simply printing out the lines. now i created a webdynpro containing a table to display these customers. I also did the binding! AND it works, but only if an event fires the execute...function. What i need is kind of "execute initially", means that the function gets executed when the table initially loads. How can i do this?

  • Running Jar file in Windows

    - by BlackPanther
    I have a "helloworld.jar" file. For running a JAR file I am using a command-line window and executing the following command: java -jar helloworld.jar By using this command I can execute the JAR file. But instead of doing it in a command-line window, I want to execute the JAR file if I double click on the JAR file. I did some Google search for this. But I cannot do this. For this do I need to install any software? Can any one provide me help on this?

  • Rx: Piecing together multiple IObservable web requests

    - by McLovin
    Hello, I'm creating multiple asynchronous web requests using IObservables and reactive extensions. So this creates observable for "GET" web request: var tweetObservalue = from request in WebRequestExtensions.CreateWebRequest(outUrl + querystring, method) from response in request.GetResponseAsync() let responseStream = response.GetResponseStream() let reader = new StreamReader(responseStream) select reader.ReadToEnd(); And I can do tweetObservable.Subscribe(response => dosomethingwithresponse(response)); What is the correct way of executing multiple asynchronous web requests with IObservables and LINQ that have to wait until other requests have been finished? For example first I would like to verify user info: create userInfoObservable, then if user info is correct I want to update stats so I get updateStatusObservable then if status is updated I would like create friendshipObservable and so on. Also bonus question, there is a case where I would like to execute web calls simultaneously and when all are finished execute another observable which will until other calls are finished. Thank you.

  • Help with Linked Server Error

    - by Randy Minder
    In SSMS 2008, I am trying to execute a stored procedure in a database on another server. The call looks something like the following: EXEC [RemoteServer].Database.Schema.StoredProcedureName @param1, @param2 The linked server is set up correctly, and has both RPC and RPC OUT set to true. Security on the linked server is set to Be made using the login's current security context. When I attempt to execute the stored procedure, I get the following error: Msg 18483, Level 14, State 1, Line 1 Could not connect to server 'RemoteServer' because '' is not defined as a remote login at the server. Verify that you have specified the correct login name. I am connected to the local server using Windows Authentication. Anyone know why I would be getting this error?

  • jQuery events .load(), .ready(), .unload()

    - by Eric
    Hi folks, Just a simple question, for the jquery event. Are the .load(), .ready() and .unload() run in order when the DOM is loaded? The answer seems yes when I see the jQuery Documentation. <script type="text/javascript"> $(window).load(function () { // run code initializeCode(); }); $(document).ready(function() { //run code that MUST be after initialize }); $(window).unload(function() { Cleanup(); }); </script> However, the code inside the .ready() is execute before the initializeCode(); is execute, so I feel really strange. And now I have to place my code inside the .onload() method and just after the initializeCode(); line, which means to be inside the .ready() block. Could someone explain me more about this, as I am new to jQuery. Thank you so much.

  • SQL Server 2005 Error 701 - out of memory

    - by Tufo
    I'm currently having following error message when executing a .sql file with about 26MB on SQL Server 2005: Msg 701, Level 17, State 123 There is insufficient system memory to run this query. I'm working with 4GB RAM, 64Bit Windows 7 Ultimate, Core2Duo T6400(2GHz)... Is there a way to execute it without receiving this message (maybe force SQL Server to use swap file?) or a way to execute it in parts (like 100 queries a time)... The file is basically a CREATE TABLE followed by thousads of INSERT queries and I have a lot of those (converted .DBF files to SQL queries using ABC DBF Converter) Any idea will be very appreciated!

  • Using pyodbc to insert rows into a MS Access MDB, how do I escape the paramaters?

    - by MDBGuy
    Hi, I'm using pyodbc to talk to a legacy Access 2000 .mdb file. I've got a cursor, and am trying to execute this: c.execute("INSERT INTO [Accounts] ([Name], [TypeID], [StatusID], [AccountCat], [id]) VALUES (?, ?, ?, ?, ?)", [u'test', 20, 10, 4, 2]) However, doing so results in pyodbc.Error: ('HYC00', '[HYC00] [Microsoft][ODBC Microsoft Access Driver]Optional feature not implemented (106) (SQLBindParameter)') I understand I can simply change the question marks to the literal values, but in my experience proper escaping of strings across databases is... not pretty. PHP and mysql team up to bring mysql_real_escape_string and friends, but I can't seem to find pyodbc's function for escaping values. If you could let me know what the recommended way of inserting this data (from python) is, that'd be very helpful. Alternatively, if you have a python function to escape the odbc strings, that would also be great. Thanks for the help.

  • Can somebody explain in a few sentences how these technologies relate: Flex, Flash, Air, ActionScrip

    - by SimpaCar
    I've read about each of these but I still don't understand how they all inter-operate, which are competing technologies, or even really what each of them is distinctly. Flash, Air, Flex... Are these all "containers"/JVM-like runtime environments, in which ActionScript code runs? SWF,FLV,AIR... Are these competing file formats which a Flash, Air or Flex runtime environment executes? ActionScript is a C-like language which compiles to SWF, FLV or AIR files? Sorry, with all the marketing around these terms, some of which are used interchangeably, I am quite lost. Suppose I wanted to write an AIR application... what would that entail? Writing ActionScript, compiling it to a SWF, and then installing the AIR runtime to execute it? How's that different than Flash? If I want to play AIR applications do I need a separate AIR runtime or does Flash execute AIR apps?

  • TAPI App on 64bits OS

    - by mvg
    I have a TAPI Application (Delphi 2007) working on 32bits OSs (XP, Vista, Win7). The TAPI server is 32bits Windows 2003 SP2. While TAPI APP is running on 64bits OS, I can connect to the line but i cannot get TAPI messages on my App. I can see messages have arrived on machine through Tracing tapisrv but the WaitForSingleObjectEx to the event handle (returned by lineInitializeEx) is never signaled (always returns WAIT_TIMEOUT). I've also tried C++ code and 64bits compiler but the 64bits App had the same behavior (except not even starting on 32bits OS :-) ). Is there any ideas how i can receive the TAPI messages to my App??? EDIT: Well, it seems that only the messages regarding incoming calls are cut. If (while App is running) i execute "tcmsetup /c /d" (=disable TAPI) then i DO receive LINE_CLOSE and LINE_REMOVE messages. Then, if i execute "tcmsetup /c server_name", i DO get the LINE_CREATE message. I can lineOpen the new line provided but still CANNOT get LINE_APPNEWCALL, LINE_CALLSTATE etc

  • Editing a 9gb .sql file

    - by CERIQ
    Hi. I've got a "slightly" large sql script saved as a textfile. It totals in at 8.92gb, so it's a bit of a beast. I've got to do some search and replaces in this file(specifically, change all NOT NULL to NULL, so all fields are nullable) and then execute the darned thing. Does anyone have any suggestions for a text editor that would be capable of this? The other way that I can see to solve the problem is to write a program that reads a chunk, does a replace on the stuff I need, and then save it to a new file, but I'd rather use some standard way of doing this. It also does not solve the problem of opening the beast up in sql server management studio to execute the darned thing... Any ideas? Thanks, Eric

  • What Easter Eggs have you placed in code?

    I know it is illegal to place Easter eggs in code via Microsoft's quarrel with the law a few years back. Microsoft has decided that if you place Easter eggs in code, it is an immediate grounds for termination, but they are still out there in the wild. I know I put my name in the code a lot that will never show up to the users, but it is always fun to do. So, what Easter eggs have you seen or placed in your programs/code?

  • UIControlEventTouchDragExit only fires ~100 pixels out

I was told in another answer to use UIControlEventTouchDragExit however this event only fires when the touch gets about 100 pixels away from the button, whereas I would like it to be immediate. The apple docs say that goes according to the bounds however my understand is the bounds and the frame are the same unless you rotate the UIbutton (or whatever)
