  • mysql innodb max size of transaction

    - by chris
    Using mysql 5.1.41 and innodb I'm doing some data import, but can't use load data infile, so I'm manually issuing insert statements. I found that it's much faster to disable auto commit and issue say, 100 insert statements and then commit, instead of the implicit commit after each insert. It got me thinking, what limits are there to how much data I can put into a transaction? Is there a limit on the number of statements, or does it have to do with the size in bytes etc...?

  • Has anyone here tried using the iSeries Python port?

    - by nearly_lunchtime
    I found http://www.iseriespython.com/, which is a version of Python for the iSeries apparently including some system specific data access classes. I am keen to try this out, but will have to get approval at work to do so. My questions are: Does the port work well, or are there limits to what the interpreter can handle compared with standard Python implementations? Does the iSeries database access layer work well, creating usable objects from table definitions?

  • How to run Cg vertex/fragment shader on CPU?

    - by Andy
    Hi all, I'm playing about with some vertex and fragment shaders using Cg on my little netbook (running Linux). Clearly I'm going to frequently hit resource limits for my graphics controller, so was wondering if there's a nice way to run the shaders on the CPU, just to test them. Something like D3D's refrast... TIA Andy

  • Is it possible to run Weblogic with 8gb heap size in a 64bit java/linux environment

    - by Per Arneng
    Setup: 64bit Linux 64bit SUN Jvm 1.6.0_20 Weblogic 10.3 Is it possible to run Weblogic 10.3 in this setup with a maximum heap size of 8gb? We have recived answers from oracle support that states that it might not be possible to address more than 4gb with this setup. Please submit any official links that support any statements that it is possible to run this setup with more than 4gb of heap size. We can not find any documentation of any limits of heap size when running with this setup. Thanx

  • JMS Topic message size

    - by jjoshi
    Our application uses a topic to push message to a small set of subscribers. what sort of things should i look for when modeling a jms message with respect to the size of the actual message to be pushed. Are there any known limits or is application server specific? Any best practices or suggestions on this topic (pun unintended)?

  • XHTML 1.0 Transitive, is there a tool that can refactor HTML?

    - by GenEric35
    I have a Asp.net web application running with the following config setting. <xhtmlConformance mode="Legacy"/> This limits use of AJAX and compatibility with multiple browser. If my understanding is correct, the HTML code of the aspx pages need to be fixed to comply with XHTML 1.0 Transitional. There are alot of HTML pages, ~1000, is there a tool that could speed up this process?

  • Difference between library and native library

    - by Alvin
    Could anyone tell me the difference between library and native library in terms of java? I found the word "native library" in the following line: Type 1 - drivers that implement the JDBC API as a mapping to another data access API, such as ODBC. Drivers of this type are generally dependent on a native library, which limits their portability. The JDBC-ODBC Bridge driver is an example of a Type 1 driver. which you can found here

  • Recommended way to perform Lucene search without limit

    - by Thomas
    The Lucene documents tell me that "Hits" will be removed from the API in Lucene 3.0. Deprecated. Hits will be removed in Lucene 3.0. Use search(Query, Filter, int) instead. The proposed overload limits the number of documents returned to the value of the int. So my question is: what is the recommended way to perform a search in Lucene with no limit on the number of documents to be returned?

  • Trying to run multiple HTTP requests in parallel, but being limited by Windows (registry)

    - by Nailuj
    I'm developing an application (winforms C# .NET 4.0) where I access a lookup functionality from a 3rd party through a simple HTTP request. I call an url with a parameter, and in return I get a small string with the result of the lookup. Simple enough. The challenge is however, that I have to do lots of these lookups (a couple of thousands), and I would like to limit the time needed. Therefore I would like to run requests in parallel (say 10-20). I use a ThreadPool to do this, and the short version of my code looks like this: public void startAsyncLookup(Action<LookupResult> returnLookupResult) { this.returnLookupResult = returnLookupResult; foreach (string number in numbersToLookup) { ThreadPool.QueueUserWorkItem(lookupNumber, number); } } public void lookupNumber(Object threadContext) { string numberToLookup = (string)threadContext; string url = @"http://some.url.com/?number=" + numberToLookup; WebClient webClient = new WebClient(); Stream responseData = webClient.OpenRead(url); LookupResult lookupResult = parseLookupResult(responseData); returnLookupResult(lookupResult); } I fill up numbersToLookup (a List<String>) from another place, call startAsyncLookup and provide it with a call-back function returnLookupResult to return each result. This works, but I found that I'm not getting the throughput I want. Initially I thought it might be the 3rd party having a poor system on their end, but I excluded this by trying to run the same code from two different machines at the same time. Each of the two took as long as one did alone, so I could rule out that one. A colleague then tipped me that this might be a limitation in Windows. I googled a bit, and found amongst others this post saying that by default Windows limits the number of simultaneous request to the same web server to 4 for HTTP 1.0 and to 2 for HTTP 1.1 (for HTTP 1.1 this is actually according to the specification (RFC2068)). The same post referred to above also provided a way to increase these limits. By adding two registry values to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings] (MaxConnectionsPerServer and MaxConnectionsPer1_0Server), I could control this myself. So, I tried this (sat both to 20), restarted my computer, and tried to run my program again. Sadly though, it didn't seem to help any. I also kept an eye on the Resource Monitor (see screen shot) while running my batch lookup, and I noticed that my application (the one with the title blacked out) still only was using two TCP connections. So, the question is, why isn't this working? Is the post I linked to using the wrong registry values? Is this perhaps not possible to "hack" in Windows any longer (I'm on Windows 7)? Any ideas would be highly appreciated :) And just in case anyone should wonder, I have also tried with different settings for MaxThreads on ThreadPool (everyting from 10 to 100), and this didn't seem to affect my throughput at all, so the problem shouldn't be there either.

  • What can you do and not do with java annotations?

    - by swampsjohn
    The typical use-case is for simple things like @Override, but clearly you can do a lot more with them. If you push the limits of them, you get things like Project Lombok, though my understanding is that that's a huge abuse of annotations. What exactly can you do? What sort of things can you do at compile-time and run-time with annotations? What can you not do?

  • Adding a view with a view controller as a subview of another view controller. Doesn't work.

    - by Tom
    I'm trying to essentially re-implement the UISplitViewController (because it has its limits), but when I create a UIViewController viewController, and then do an "[viewController.view addSubview contentViewController.view]" on it, to add a view that already has a view controller, that content view doesn't seem to get initialised by its view controller. I guess its view controller is getting detached or deallocated, is this the case?

  • Is it possible in .NET to set the local endpoint (IP address) when using webclient to consume a web

    - by Tom
    I'm wondering if it is possible using .NET to call a remote web service and in effect specify which IP the call is made on. I'm consuming a service that limits the number of calls I can make based on IP. The service costs in the 20k range after the free limit is used up. I'm very close to enough calls but not quite there using the free service. My server has 3 IP so I could in effect triple the number of calls I could make to the remote service by changing the IP.

  • Measuring the limit of a point on a smooth.spline in R

    - by Subtle Array
    I'm not sure if that's the right terminology. I've entered some data into R, and I've put a smoothingSpline through it using the following command. smoothingSpline = smooth.spline(year, rate, spar=0.35) plot(x,y) lines(smoothingSpline) Now I'd like to measure some limits (or where the curve is at a given y point), and maybe to some predictive analysis on points that extend beyond the graph. Are there commands in R for doing this?
