• What is the typical maximum number of database connections for Oracle running on Windows server ?

  - by Sake

  We are maintaining a database server that serve a large number of clients. Each client typically running serveral client-applications. The total number of connections to the database server (Oracle 9i) is reaching 800 connections on peak load. The windows 2003 server is starting to run out of memory. We are now planning to move to 64bit Windows in order to gain higher memory capability. As a developer I suggest moving to multi-tier architecture with conneciton pooling, which I believe is a natural solution to this problem. However, in order to support my idea, I want the information on: what exactly is the typical number of connections allowed for Oracle database ? What is the problem when the number connections is too high ? Too much memory comsumption ? or too many sockets opened ? or too many context switching between threads ? To be a little bit specific, how could Oracle Forms application scale to thousand of users without facing this problem ? Shall Oracle RAC applied to this case ? I'm sure the answer to this question should depend on quite a number of factors, like the exact spec of the hardware being used. I'm expecting a rough estimation or some experience from the real world.

• How do I find the Serial Number of a USB Drive?

  - by jamuraa

  I'm trying to re-enable USB Autoplay in a secure way, by installing a program on each of the computers that I use so that I can run my launcher (PStart in this case) whenever I plug in my specific USB drive. The tool that I'm using to enable this - AutoRunGuard - needs the serial number of the USB drive that I am using. I can't figure out where to find this in Windows. Ideally I would not need to install and run a separate program to do this (seemingly) simple task. Since this is a pretty easy question, bonus points if you also tell me how to discover it in Linux as well. What steps do I need to take to retrieve a USB Drive's serial number? UPDATE: Just incase people come here looking for the answer for AutoRunGuard, I discovered that they don't want the USB device serial number, but the volume serial number. The drive serial can be found by going into the command line, navigating to the drive, and executing dir. The volume serial number is found in the top two lines - use it without the dash.

• how to know which display number for the variable DISPLAY to be exported when ssh to server

  - by insidepower

  When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only export DISPLAY=localhost:0 && xclock export DISPLAY=localhost:1 && xclock export DISPLAY=localhost:2 && xclock export DISPLAY=localhost:... until the clock appear. Then i will use that display number. Each time log in to the server, the display number which is able to tunnel the gui data correct would be different. I know many of such similar questions has been asked and answer. However I couldn't find answer to my question, anyone know about it? Thanks!

• How to auto dial 9+Number on Cisco 7941 redial?

  - by NotDan

  Is it possible to set up a Cisco 7941 phone to dial 9 before the redial number? When I view missed calls, and try to redial one of the numbers, it always fails because it doesn't dial 9 first. I have to write the number down and then manually dial the 9 and then the number.

• How do I install Flash Player 11 debug version in 11.10?

  - by shanethehat

  I want to replace my existing browser plugin Flash Player with the debug version, and update to FP11 while I'm at it. I also want to install the debug version of the projector player and make it the default player for SWF files outside of the browser. First the browser plugin version. I've downloaded the installer from the official site, but I'm not sure what to do with the contents. There is a usr folder, and I presume that I am to write the contents of this to /usr. There is also a file called libflashplayer.so, and I have no idea what to do with that. For download for the projector player has confused me further because it only contains one file: flashplayerdebugger. I don't know what to do with this. If there is a way to install these softwares through apt-get or the Software Center I would love to hear about it, I have only found solutions for the standard player, but otherwise could someone please tell me what to do with these files? Update Ok, so I've figured out that if I dump the flashplayerdebugger file into /usr/lib/ I can point Eclipse at it and compile and test SWFs as expected from inside Eclipse. But how can I set that application as the default player when I select an SWF in Nautilus?

• Ubuntu 12.04 OpenCL with Intel and Radeon?

  - by Steve

  I want to setup my Ubuntu 12.04 with OpenCL(Open Computing Language) support for i7 2600k and Radeon HD5870. My Monitor is connected to the integrated Graphics of the i7. Intel OpenCL SDK is installed and working. Iteration of avaliable OpenCL devices shows 2 entries for Intel. As recommended I installed AMD APP SDK 2.6 first and then the fglrx driver. I installed fglrx from Ubuntu repositories. This works fine till here. When I run aticonfig --inital -f and restart the system I get into trouble.

• How do I source a shell script for Node Version Manager?

  - by Matthew Patrick Cashatt

  Hi and thanks for looking! I am new to Linux/Ubuntu, but I have set up an Ubuntu box on which to run Node.js. I have had moderate success, but now I need to be able to easily upgrade my version of Node. Many folks recommend using Node Version Manager. I followed the directions, but when I try to do something like this: nvm ls I get a messaging stating that No command NVM found I have gone back to check the steps I followed to install NVM, but there is one part that is tricky for may and I think to be the culprit: sourcing the file for bash. From the instructions: To activate nvm, you need to source it from your bash shell . ~/nvm/nvm.sh I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login. Often I also put in a line to use a specific version of node. So which file should I add this to? I am guessing profile since it's ubuntu?? Also, where in the file do I add this line? After I have added this line, do I need to reboot or anything? Any help would be deeply appreciated--especially if you can show me an example profile file with . ~/nvm/nvm.sh integrated so that I can see usage. Thanks, Matt

• When will a newer version of flex for windows be available?

  - by Jorn

  I'm using flex (lexical analyzer, not Adobe Flex) on a project. However, I want to be able to compile on Windows platforms as well, but the Windows version's newest version is only 2.5.4a, so it won't compile my file for version 2.5.35. And no, I can't downgrade to the highest supported Windows version. Anyone know about plans to upgrade the windows version, or have a suggestion to compile on windows anyway?

• Algorithm to add two digits to the end of a number to calculate a specific modulus?

  - by Jim

  So, lets say I have a number 123456. 123456 % 97 = 72. How can I determine what two digits need to be added to the end of 123456 such that the new number % 97 = 1? Note--it must always be two digits. For example, 12345676 % 97 = 1. In this case, I need to add the digits "76" to the end of the number. (This is for IBAN number calculation.)

• How do I install the latest version of packages in Ubuntu?

  - by Roman

  For example I want to install the latest version of "numpy". I type the following: "sudo apt-get install python-numpy". When I type this the first time it installs something and if I type this the second time it writes that I have already the latest version of numpy. However, I see that my version of numpy is 1.1.1. and I know that it NOT the latest version. Why it happens and how this problem can be solved? I can find the *tar.gz file with the latest version, I can extract files with the archive and than I need to rune one of the scripts which will be somewhere among the extracted files. But I do not like this way. It is too complicated. I do not know where I should put all these files, I do not know which dependencies I should install before I run the script for the installation of numpy, I do not know where numpy will be put after installation and so on. Is there an easy way to get the latest version of numpy?

• Why did Ubuntu suddenly get so slow?

  - by user101383

  12.10 has been slowing down mysteriously. Normally, in past versions, I can log in, open Firefox, and it will pop up within seconds. 12.10 is like that upon install too, though once I install my old apps, it gets very slow by Ubuntu standards.

• How to obtain a random sub-datatable from another data table

  - by developerit

  Introduction In this article, I’ll show how to get a random subset of data from a DataTable. This is useful when you already have queries that are filtered correctly but returns all the rows. Analysis I came across this situation when I wanted to display a random tag cloud. I already had the query to get the keywords ordered by number of clicks and I wanted to created a tag cloud. Tags that are the most popular should have more chance to get picked and should be displayed larger than less popular ones. Implementation In this code snippet, there is everything you need. ' Min size, in pixel for the tag Private Const MIN_FONT_SIZE As Integer = 9 ' Max size, in pixel for the tag Private Const MAX_FONT_SIZE As Integer = 14 ' Basic function that retreives Tags from a DataBase Public Shared Function GetTags() As MediasTagsDataTable ' Simple call to the TableAdapter, to get the Tags ordered by number of clicks Dim dt As MediasTagsDataTable = taMediasTags.GetDataValide ' If the query returned no result, return an empty DataTable If dt Is Nothing OrElse dt.Rows.Count < 1 Then Return New MediasTagsDataTable End If ' Set the font-size of the group of data ' We are dividing our results into sub set, according to their number of clicks ' Example: 10 results -> [0,2] will get font size 9, [3,5] will get font size 10, [6,8] wil get 11, ... ' This is the number of elements in one group Dim groupLenth As Integer = CType(Math.Floor(dt.Rows.Count / (MAX_FONT_SIZE - MIN_FONT_SIZE)), Integer) ' Counter of elements in the same group Dim counter As Integer = 0 ' Counter of groups Dim groupCounter As Integer = 0 ' Loop througt the list For Each row As MediasTagsRow In dt ' Set the font-size in a custom column row.c_FontSize = MIN_FONT_SIZE + groupCounter ' Increment the counter counter += 1 ' If the group counter is less than the counter If groupLenth <= counter Then ' Start a new group counter = 0 groupCounter += 1 End If Next ' Return the new DataTable with font-size Return dt End Function ' Function that generate the random sub set Public Shared Function GetRandomSampleTags(ByVal KeyCount As Integer) As MediasTagsDataTable ' Get the data Dim dt As MediasTagsDataTable = GetTags() ' Create a new DataTable that will contains the random set Dim rep As MediasTagsDataTable = New MediasTagsDataTable ' Count the number of row in the new DataTable Dim count As Integer = 0 ' Random number generator Dim rand As New Random() While count < KeyCount Randomize() ' Pick a random row Dim r As Integer = rand.Next(0, dt.Rows.Count - 1) Dim tmpRow As MediasTagsRow = dt(r) ' Import it into the new DataTable rep.ImportRow(tmpRow) ' Remove it from the old one, to be sure not to pick it again dt.Rows.RemoveAt(r) ' Increment the counter count += 1 End While ' Return the new sub set Return rep End Function Pro’s This method is good because it doesn’t require much work to get it work fast. It is a good concept when you are working with small tables, let says less than 100 records. Con’s If you have more than 100 records, out of memory exception may occur since we are coping and duplicating rows. I would consider using a stored procedure instead.

• How to get 32 bit version of libraries on Ubuntu 64 bit?

  - by Olivier Lalonde

  I'm trying to compile a program which uses Google's V8 library (which is 32 bit). Therefore any library I use within my program also has to be 32 bit. Where can I download the 32 bit version of libraries on Ubuntu 64 bit? More specifically, I'm looking for the libnotify 32 bit version. This is the errors I am getting right now: g++ -o shell -m32 shell.o -L../v8 -lv8 -lpthread `pkg-config --libs libnotify glib-2.0` /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.3/../../../libnotify.so when searching for -lnotify /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.3/../../../libnotify.a when searching for -lnotify /usr/bin/ld: skipping incompatible /usr/lib/libnotify.so when searching for -lnotify /usr/bin/ld: skipping incompatible /usr/lib/libnotify.a when searching for -lnotify /usr/bin/ld: cannot find -lnotify collect2: ld returned 1 exit status Thanks!

• Stage3D Camera problem

  - by Thomas Versteeg

  I am trying to create a 2D Stage3D game where you can move the camera around the level in an RTS style. I thought about using Orthographic Matrix3D functions for this but when I try to scroll the whole "stage" also scrolls. This is the Camera code: public function Camera2D(width:int, height:int, zoom:Number = 1) { resize(width, height); _zoom = zoom; } public function resize(width:Number, height:Number):void { _width = width; _height = height; _projectionMatrix = makeMatrix(0, width, 0, height); _recalculate = true; } protected function makeMatrix(left:Number, right:Number, top:Number, bottom:Number, zNear:Number = 0, zFar:Number = 1):Matrix3D { return new Matrix3D(Vector.<Number>([ 2 / (right - left), 0, 0, 0, 0, 2 / (top - bottom), 0, 0, 0, 0, 1 / (zFar - zNear), 0, 0, 0, zNear / (zNear - zFar), 1 ])); } public function get viewMatrix():Matrix3D { if (_recalculate) { _recalculate = false; _viewMatrix.identity(); _viewMatrix.appendTranslation( -_width / 2 - _x, -_height / 2 - y, 0); _viewMatrix.appendScale(_zoom, _zoom, 1); _renderMatrix.identity(); _renderMatrix.append(_viewMatrix); _renderMatrix.append(_projectionMatrix); } return _renderMatrix; } Here are two screenshots to show what I mean: How do I only let the inside of the stage3D scroll and not the whole stage?

• How do I install an older 2.6.37 Kernel Version?

  - by Seyed Mohammad

  I have a Sony VAIO P netbook and for several issues (graphics driver, audio driver and power management), I want to install an older version of the Linux kernel on Ubuntu 11.10 (actually its Xubuntu) that seems to be much more suitable. So I searched for Ubuntu kernels and found this link which includes all versions of the Linux kernel distributed by Ubuntu. I am looking for a version before 2.6.38 (to escape the known power management issue) and of course solve my many driver problems! I guess my best bet is 2.6.37 but there are several 2.6.37.x-x kernels! Can someone point me to the right choice? In each folder (for example: this one) there are several DEB packages. Which packages should I install? (Note: I have a 32-bit system) What is the installation process? sudo dpkg -i *.deb ? Is this fine or additional steps are required? Thanks.

This is the Camera code: public function Camera2D(width:int, height:int, zoom:Number = 1) { resize(width, height); _zoom = zoom; } public function resize(width:Number, height:Number):void { _width = width; _height = height; _projectionMatrix = makeMatrix(0, width, 0, height); _recalculate = true; } protected function makeMatrix(left:Number, right:Number, top:Number, bottom:Number, zNear:Number = 0, zFar:Number = 1):Matrix3D { return new Matrix3D(Vector.<Number>([ 2 / (right - left), 0, 0, 0, 0, 2 / (top - bottom), 0, 0, 0, 0, 1 / (zFar - zNear), 0, 0, 0, zNear / (zNear - zFar), 1 ])); } public function get viewMatrix():Matrix3D { if (_recalculate) { _recalculate = false; _viewMatrix.identity(); _viewMatrix.appendTranslation( -_width / 2 - _x, -_height / 2 - y, 0); _viewMatrix.appendScale(_zoom, _zoom, 1); _renderMatrix.identity(); _renderMatrix.append(_viewMatrix); _renderMatrix.append(_projectionMatrix); } return _renderMatrix; } And the camera is send directly to the GPU with: c3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 0, cameraMatrix, true); And these are the shaders: ------Vertex Shader------ m44 op, va0, vc0 mov v0, va1.xy mov v0.z, va0.z ------Fragment Shader------ tex ft0, v0, fs0 <2d,linear,nomip> mov oc, ft1 Here is a example and here are two screenshots to show what I mean: How do I only let the inside of the stage3D scroll and not the whole stage?

• Is there a rational reason to wait for the release date to download, install or update to the next version of Ubuntu?

  - by badp

  Today, October 6th 2010, Ubuntu 10.10 is in Feature Definition Freeze, Debian Import Freeze, Feature Freeze, User Interface Freeze, Beta Freeze, Documentation String Freeze, Final Freeze, Kernel Freeze and past the Translation Deadlines in both the non-language pack and language pack editions as the release schedule details. Basically, except for last minute bugfixes, the version of Ubuntu 10.10 you can download today is identical to the version of Ubuntu 10.10 you can download on the 10th when it gets released. If you downloaded and installed Ubuntu 10.10 today, you would: help find glaring issues for last minute fixing help defray the network load on October 10th see Ubuntu 10.10 in action without waiting Those sound like pretty strong arguments... to me, and indeed I've been using Ubuntu 10.10 for a month now roughly. However, most people prefer to make the jump with everybody else on release day. What are the rational reasons for that?

• What is the version numbering logic for open source developers managing software releases?

  - by Stephen Myall

  I guess this is more of a general question that I cant find the the answer to anywhere. What is the version numbering logic for open source developers managing software releases and is there any governance or guidance I can read up on. The origins of this question comes from me reviewing and researching software on countless websites that I would like to use on my Ubuntu OS. Through experience, I am learning some sites are much better than others explaining if a release is a stable, experimental or maintenance release but these explanations are not consistent with any version numbering logic I am familiar with.

• How can a large, Fortran-based number crunching codebase be modernized?

  - by Dave Mateer

  A friend in academia asked me for advice (I'm a C# business application developer). He has a legacy codebase which he wrote in Fortran in the medical imaging field. It does a huge amount of number crunching using vectors. He uses a cluster (30ish cores) and has now gone towards a single workstation with 500ish GPUS in it. However where to go next with the codebase so: Other people can maintain it over next 10 year cycle Get faster at tweaking the software Can run on different infrastructures without recompiles After some research from me (this is a super interesting area) some options are: Use Python and CUDA from Nvidia Rewrite in a functional language. For example, F# or Haskell Go cloud based and use something like Hadoop and Java Learn C What has been your experience with this? What should my friend be looking at to modernize his codebase? UPDATE: Thanks @Mark and everyone who has answered. The reasons my friend is asking this question is that it's a perfect time in the projects lifecycle to do a review. Bringing research assistants up to speed in Fortran takes time (I like C#, and especially the tooling and can't imagine going back to older languages!!) I liked the suggestion of keeping the pure number crunching in Fortran, but wrapping it in something newer. Perhaps Python as that seems to be getting a stronghold in academia as a general-purpose programming language that is fairly easy to pick up. See Medical Imaging and a guy who has written a Fortran wrapper for CUDA, Can I legally publish my Fortran 90 wrappers to Nvidias' CUFFT library (from the CUDA SDK)?.

• Ubuntu has LTS and normal version now. Does Lubuntu have the same?

  - by Elysium

  I am wondering if this is the right place for this question, but if not...then the moderators will surely tell me so. Anyway....there is Ubuntu 12.04 LTS and the normal 12.10 version. Is that the same with Lubuntu? On their site, for some reason, they seem to be promoting the 12.10 version while for me an LTS is always more appealing. I am wondering if they have the same ideology as the Ubuntu team. UPDATE: Is it okay to talk about Lubuntu here at all? I understand that it is a flavour of Ubuntu...but still. Are they 2 very different teams?

• Upgrading Beta to full version work without bugs? [closed]

  - by Nicky Bailuc

  Possible Duplicate: I installed an alpha or beta, am I up to date with the final release if I keep upgrading? When the Beta version of 13.4 comes out, I would like to install it and therefore put all my programs, files, and data on it. On the 18th when the original version of 13.4 comes out, will I be able to upgrade the beta into the original without any issues and successfully run it without bugs. I'm asking this because when i upgraded 12.4 to 12.10 it had a lot of glitches to it. Will the 13.4 run the same after upgrading as if I was to install the it directly as it is?
