• xsltproc killed, out of memory

  - by David Parks

  I'm trying to split up a 13GB xml file into small ~50MB xml files with this XSLT style sheet. But this process kills xsltproc after I see it taking up over 1.7GB of memory (that's the total on the system). Is there any way to deal with huge XML files with xsltproc? Can I change my style sheet? Or should I use a different processor? Or am I just S.O.L.? <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:exsl="http://exslt.org/common" extension-element-prefixes="exsl" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:output method="xml" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:param name="block-size" select="75000"/> <xsl:template match="/"> <xsl:copy> <xsl:apply-templates select="mysqldump/database/table_data/row[position() mod $block-size = 1]" /> </xsl:copy> </xsl:template> <xsl:template match="row"> <exsl:document href="chunk-{position()}.xml"> <add> <xsl:for-each select=". | following-sibling::row[position() &lt; $block-size]" > <doc> <xsl:for-each select="field"> <field> <xsl:attribute name="name"><xsl:value-of select="./@name"/></xsl:attribute> <xsl:value-of select="."/> </field> <xsl:text>&#xa;</xsl:text> </xsl:for-each> </doc> </xsl:for-each> </add> </exsl:document> </xsl:template>

• Remote synchronization

  - by Tomas Mysik

  Hi all, today we would like to show you another improvement we have prepared for NetBeans 7.2. Today, let's talk a little bit about remote synchronization. If you already use our simple (S)FTP client, this enhancement could be useful for you. Simply right click on Source Files and select Synchronize. Please notice that the remote synchronization works better only on the whole project (it means that the Source Files must be selected). The Synchronize action is also available on individual files (more files can be selected at once) but the suggested operation (download, upload etc.) does not work so precisely. Also please notice that the suggested operations are not 100% reliable since the timestamps provided by FTP servers are not exact. Once the remote files (their names and paths only, of course) are fetched, the main dialog appears: As you can see, NetBeans tries to suggest you operations (upload, download etc.) which should be done for each individual file of your project. If you are interested only in some particular changes, you can simply filter the list: Since we have a file conflict, we need to resolve it first. Fortunately this is very easy because we just select the desired file and click the Diff button . The remote version of our file is downloaded and compared with the local version. The resut is displayed in the dialog where you can easily apply and/or refuse the remote changes or even simply type manually to the local version of the selected file: Once we are done with our changes, the operation for the selected file changes to Upload and the file is marked with * (since we made some changes). Please notice that if you now click the Cancel button, in fact no changes are done in our local file. As you can see, if we have one or more files selected, we can change their operation to: no operation (file won't be synchronized) download upload delete (both local and remote file) reset (the operation is resetted to the original one suggested by NetBeans and also all changes done via Diff action are discarded) Now we are ready to synchronize our project. NetBeans will show us the synchronization summary (this dialog can be omitted, see the Show Summary checkbox on the previous image). The synchronization itself starts and we can see its progress and of course its result. As always, all the operations can be reviewed in the Output window. That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans BugZilla (component php, subcomponent FTP support).

• Tweaking Remote Control (In-Kernel LIRC)

  - by Geoff

  I've recently rebuilt my MythTV box using Mythbuntu 12.04, to take advantage of newer hardware (Ivy Bridge). On my previous build I used lirc to manage the remote, i.e. the mapping of key codes - keypresses - application keys; it was quite a journey to learn it all, and I ended up fairly comfortable with how it all worked. What I have: I have a cheap Chinavasion remote and USB dongle, which I've found several articles on; these largely revolve around working with XBMC (interesting, but I don't think directly applicable) and also around getting a Harmony remote to work (it's a Chinavasion CVSB-983 - very useful, since I needed this to get my Harmony 900 working). Mythbuntu 12.04 64-bit MythTV 0.25 (likely irrelevant) How it is right now When I plug this in, it 'just works'. Which is great, except that Ubuntu uses it natively, and prevents some of the button presses from getting through to Myth. For example, I can send a button from the remote that equates to Ctrl-Alt-A (which I assume Ubuntu isn't interested in), and then trap that in Mythfrontend, but the remote's Play button is caught by Ubuntu (which displays a large circle with a line though it, as there's no media player loaded). I understand that this is because lirc is merged into the kernel now, and I like that. What I've done so far: Found the device using lsusb: $ lsusb Bus 001 Device 004: ID 073a:2230 Chaplet Systems, Inc. infrared dongle for remote Found the event device number: $ cat /proc/bus/input/devices I: Bus=0003 Vendor=073a Product=2230 Version=0110 N: Name="HID 073a:2230" P: Phys=usb-0000:00:1a.0-1.2/input0 S: Sysfs=/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2:1.0/input/input5 U: Uniq= H: Handlers=sysrq kbd mouse1 event5 js0 B: PROP=0 B: EV=10001f B: KEY=4c37fff072ff32d bf54445600000000 ffffffffff 30c100b17c007 ffa67bfad951dfff febeffdfffefffff fffffffffffffffe B: REL=343 B: ABS=100030000 B: MSC=10 Tested the input with evtest (I pressed Play): $ sudo evtest /dev/input/event5 Input driver version is 1.0.1 Input device ID: bus 0x3 vendor 0x73a product 0x2230 version 0x110 Input device name: "HID 073a:2230" Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 1 (KEY_ESC) Event code 2 (KEY_1) Event code 3 (KEY_2) Event code 4 (KEY_3) Event code 5 (KEY_4) Event code 6 (KEY_5) Event code 7 (KEY_6) <------------snipped lots of 'Event code' lines------------> Testing ...

I'd like to either remap each button press to something that Ubuntu/Unity will ignore, or even better pass the keypress directly to Myth (I suspect this later is only possible with lirc, but I could be wrong). I would really like to do this with the in-kernel drivers, i.e. without explicitly loading lirc; if that's the way the world is going, I'd rather find a way to map the current behaviour to what I want, rather than forcing the 'old' arrangement of loading lirc outside the kernel. Learning something new is also worthwhile! My guess: I'm assuming that this will require using setkeycodes, but have had trouble finding enough information to configure this. Any help greatly appreciated!

• Performing an upgrade from TFS 2008 to TFS 2010

  - by Enrique Lima

  I recently had to go through the process of migrating a TFS 2008 SP1 to a TFS 2010 environment. I will go into the details of the tasks that I went through, but first I want to explain why I define it as a migration and not an upgrade. When this environment was setup, based on support and limitations for TFS 2008, we used a 32 bit platform for the TFS Application Tier and Build Servers.  The Data Tier, since we were installing SP1 for TFS 2008, was done as a 64 bit installation.  We knew at that point that TFS 2010 was in the picture so that served as further motivation to make that a 64bit install of SQL Server.  The SQL Server at that point was a single instance (Default) installation too.  We had a pretty good strategy in place for backups of the databases supporting the environment (and this made the migration so much smoother), so we were pretty familiar with the databases and the purpose they serve. I am sure many of you that have gone through a TFS 2008 installation have encountered challenges and trials.  And likely even more so if you, like me, needed to configure your deployment for SSL.  So, frankly I was a little concerned about the process of migrating.  They say practice makes perfect, and this environment I worked on is in some way my brain child, so I was not ready nor willing for this to be a failure or something that would impact my client’s work. Prior to going through the migration process, we did the install of the environment.  The Data Tier was the same, with a new Named instance in place to host the 2010 install.  The Application Tier was in place too, and we did the DefaultCollection configuration to test and validate all components were in place as they should. Anyway, on to the tasks for the migration (thanks to Martin Hinselwood for his very thorough documentation): Close access to TFS 2008, you want to make sure all code is checked in and ready to go.  We stated a difference of 8 hours between code lock and the start of migration to give time for any unexpected delay.  How do we close access?  Stop IIS. Backup your databases.  Which ones? TfsActivityLogging TfsBuild TfsIntegration TfsVersionControl TfsWorkItemTracking TfsWorkItemTrackingAttachments Restore the databases to the new Named Instance (make sure you keep the same names) Now comes the fun part! The actual import/migration of the databases.  A couple of things happen here. The TfsIntegration database will be scanned, the other databases will be checked to validate they exist.  Those databases will go through a process of data being extracted and transferred to the TfsVersionControl database to then be renamed to Tfs_<Collection>. You will be using a tool called tfsconfig and the option import. This tool is located in the TFS 2010 installation path (C:\Program Files\Microsoft Team Foundation Server 2010\Tools),  the command to use is as follows:    tfsconfig import /sqlinstance:<instance> /collectionName:<name> /confirmed Where <instance> is going to be the SQL Server instance where you restored the databases to.  <name> is the name you will give the collection. And to explain /confirmed, well this means you have done a backup of the databases, why?  well remember you are going to merge the databases you restored when you execute the tfsconfig import command. The process will go through about 200 tasks, once it completes go to Team Foundation Server Administration Console and validate your imported databases and contents. We’ll keep this manageable, so the next post is about how to complete that implementation with the SSL configuration.

• How do you play or record audio (to .WAV) on Linux in C++? [closed]

  - by Jacky Alcine

  Hello, I've been looking for a way to play and record audio on a Linux (preferably Ubuntu) system. I'm currently working on a front-end to a voice recognition toolkit that'll automate a few steps required to adapt a voice model for PocketSphinx and Julius. Suggestions of alternative means of audio input/output are welcome, as well as a fix to the bug shown below. Here is the current code I've used so far to play a .WAV file: void Engine::sayText ( const string OutputText ) { string audioUri = "temp.wav"; string requestUri = this->getRequestUri( OPENMARY_PROCESS , OutputText.c_str( ) ); int error , audioStream; pa_simple *pulseConnection; pa_sample_spec simpleSpecs; simpleSpecs.format = PA_SAMPLE_S16LE; simpleSpecs.rate = 44100; simpleSpecs.channels = 2; eprintf( E_MESSAGE , "Generating audio for '%s' from '%s'..." , OutputText.c_str( ) , requestUri.c_str( ) ); FILE* audio = this->getHttpFile( requestUri , audioUri ); fclose(audio); eprintf( E_MESSAGE , "Generated audio."); if ( ( audioStream = open( audioUri.c_str( ) , O_RDONLY ) ) < 0 ) { fprintf( stderr , __FILE__": open() failed: %s\n" , strerror( errno ) ); goto finish; } if ( dup2( audioStream , STDIN_FILENO ) < 0 ) { fprintf( stderr , __FILE__": dup2() failed: %s\n" , strerror( errno ) ); goto finish; } close( audioStream ); pulseConnection = pa_simple_new( NULL , "AudioPush" , PA_STREAM_PLAYBACK , NULL , "openMary C++" , &simpleSpecs , NULL , NULL , &error ); for (int i = 0;;i++ ) { const int bufferSize = 1024; uint8_t audioBuffer[bufferSize]; ssize_t r; eprintf( E_MESSAGE , "Buffering %d..",i); /* Read some data ... */ if ( ( r = read( STDIN_FILENO , audioBuffer , sizeof (audioBuffer ) ) ) <= 0 ) { if ( r == 0 ) /* EOF */ break; eprintf( E_ERROR , __FILE__": read() failed: %s\n" , strerror( errno ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } /* ... and play it */ if ( pa_simple_write( pulseConnection , audioBuffer , ( size_t ) r , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_write() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } usleep(2); } /* Make sure that every single sample was played */ if ( pa_simple_drain( pulseConnection , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_drain() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } } NOTE: If you want the rest of the code to this file, you can download it here directly from Launchpad.

• apt-get install is not able to access /etc

  - by HorusKol

  I put together an ubuntu 12.04 server a couple of weeks ago and everything seemed fine until this morning. Suddenly, I'm having trouble installing new packages - at first I thought there was something wrong with tinyproxy and so I tried installing squid instead. However, I get similar results: Starting tinyproxy: tinyproxy: Could not open config file "/etc/tinyproxy.conf".\ ... /var/lib/dpkg/info/squid3.postinst: 1: /var/lib/dpkg/info/squid3.postinst: cannot open /etc/squid3/squid.conf: No such file It seems that apt-get is not creating the configuration files needed for these programs. I haven't modified any configuration or user groups since the last successful update/install of packages. /etc is present, and is populated with a nice healthy tree of configuration files. It is owned and grouped to root, and has the properties drwxr-xr-x - all the files and folders inside seem to be fine to, as far as I can tell. I've even been able to edit/save a couple as sudo.

• JDeveloper 11g R1 (11.1.1.4.0) - New Features on ADF Desktop Integration Explained

  - by juan.ruiz

  One of the areas that introduced many new features on the latest release (11.1.1.4.0)  of JDeveloper 11g R1 is ADF Desktop integration - in this article I’ll provide an overview of these new features. New ADF Desktop Integration Ribbon in Excel - After installing the ADF desktop integration add-in and depending on the mode in which you open the desktop integration workbook, the ADF Desktop integration ribbon for design time and runtime are displayed as a separate tab within Excel. In previous version the ADF Desktop integration environment used to be placed inside the add-ins tab. Above you can see both, design time ribbon as well as runtime ribbon. On the design time ribbon you can manage the workbook and worksheet properties, worksheet component properties, diagnostics, execution and publication of the workbook. The runtime version of the ribbon is totally customizable and represents what it used to be the runtime menu on the spreadsheet, in this ribbon you can include all the operations and actions that could be executed by the end user while working with the spreadsheet data. Diagnostics - A very important aspect for developers is how to debug or verify the interactions of the client with the server, for that ADF desktop integration has provided since day one a series of diagnostics tools. In this release the diagnostics tools are more visible and are really easy to configure. You can access the client console while testing the workbook, or you can simple dump all the messages to a log file – having the ability of setting the output level for both. Security - There are a number of enhancements on security but the one with more impact for developers is tha security now is optional when using ADF Desktop Integration. Until this version every time that you wanted to work with ADFdi it was a must that the application was previously secured. In this release security is optional which means that if you have previously defined security on your application, then you must secure the ADFdi servlet as explained in one of my previous (ADD LINK) posts. In the other hand, if but the time that you start working with ADFdi you have not defined security, you can test and publish your workbooks without adding security. Support for Continuous Integration - In this release we have added tooling for continuous integration building. in the ADF desktop integration space, the concept translates to adding functionality that developers can use to publish ADFdi workbooks as part of their entire application build. For that purpose, we have a publish tool that can be easily invoke from an ANT task such that all the design time workbooks are re-published into the latest version of the application building process. Key Column - At runtime, on any worksheet containing editable tables you will notice a new additional column called the key column. The purpose of this column is to make the end user aware that all rows on the table need to be selected at the time of sorting. The users cannot alter the value of this column. From the developers points of view there are no steps required in order to have the key column included into the worksheets. Installation and Creation of New Workbooks - Both use cases can be executed now directly from JDeveloper. As part of the Tools menu options the developer can install the ADF desktop integration designer. Also, creating new workbooks that previously was done through that convert tool shipped with JDeveloper is now automatic done from the New Gallery. Creating a new ADFdi workbook adds metadata information information to the Excel workbook so you can work in design time. Other Enhancements Support for Excel 2010 and the ADF components ready-only enabled don’t allow to change its value – the cell in Excel is automatically protected, this could cause confusion among customers of previous releases.

• Getting Started with NASM

  - by MarkPearl

  Today I got to play with NASM. This is an assembler and disassembler that can be used to write 16-bit, 32-bit & 64-bit programs. Let me say upfront that the last time I looked at assembly code at any depth was when I was studying Computer Science in Pietermaritzburg – ten years ago – and we never ever got to touch any real assembly code so a lot of what I am looking at today is very new to me. The first thing I did was download NASM compiler. This turned out to be a bit more complicated than I thought. Originally I went to http://www.nasm.us/ and downloaded the nasm-2.09.04.zip file which I thought had all I needed. No luck! It seemed to just have the uncompiled code, and from what I could tell I would need to recompile and build it – possibly in c++? Well, I wasn’t going to waste my time with that, so a bit more searching and I found the Win32 (http://www.nasm.us/pub/nasm/releasebuilds/2.09.04/win32/) folder Nasm.exe which I downloaded. Choosing an IDE So, I have NASM compiler but to compile anything you need to pass a string of special characters in the command prompt. That’s fine if I was going to just do one program once every couple of years, but since I am aiming to do quite a bit more exploration of NASM I began searching for an IDE. There were a few options, even apparently Visual Studio with a bit of tweeking could do the job, but from past experience I wanted to avoid the VS route as it can sometimes get confusing. I eventually settled on TextPad which I had used a few years ago for a similar project and it had been simple enough yet powerful enough to do the job. A bit of searching and I found a syntax file for NASM and everything seemed hunky dory. Configuring TextPad to run the NASM Compiler Next was to get TextPad to run the NASM compiler. TextPad has this external tools option that allows one to configure special commands. To simplify the process I first created a bat file in the NASM directory that allowed me to simply compile asm files. The bat file was called as.bat and had just one line of code… nasm -f bin %1.asm -o %1.com -l %1.lst Once I had created as.bat I just needed to go into TextPad and create a tool. I have made a quick video of that just showing you where the various settings are which is viewable below. The 64Bit Problem So I now have an ‘IDE’ linked to my NASM compiler so everything should be fine right? No! Whenever I tried to compile an asm program it compiles fine, but when I try and run it I get an error – “This version of the file is not compatible with the version Windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." Well.. it turns out there are a few complications with having a 64 bit OS! So after searching google and coming to any real solution that I could find other than perhaps attempting to build the code for nasm, I eventually resorted to running a VM with Windows XP on it and putting NASM there… My first hello world program So I attempt my first hello world program as per an example I found… the code was quite simple and is shown below… bits16 org 0x100 jmp main message: db 'Hello World',0ah,0dh,'$' main: mov dx,message mov ah,09 int 21h int 20h Running the build tool from TextPad and everything compiles fine and I now have a console app with helllo world shown. Conclusion It’s very early days with NASM. I have been spoilt with Visual Studio and high order languages so I assume it will be a painful ride getting into the basics of assembly programming but I am hoping that at the end of it, I will at least have a bit more exposure to a language closer to the metal.

• Multiple render targets and gamma correctness in Direct3D9

  - by Mario

  Let's say in a deferred renderer when building your G-Buffer you're going to render texture color, normals, depth and whatever else to your multiple render targets at once. Now if you want to have a gamma-correct rendering pipeline and you use regular sRGB textures as well as rendertargets, you'll need to apply some conversions along the way, because your filtering, sampling and calculations should happen in linear space, not sRGB space. Of course, you could store linear color in your textures and rendertargets, but this might very well introduce bad precision and banding issues. Reading from sRGB textures is easy: just set SRGBTexture = true; in your texture sampler in your HLSL effect code and the hardware does the conversion sRGB-linear for you. Writing to an sRGB rendertarget is theoretically easy, too: just set SRGBWriteEnable = true; in your effect pass in HLSL and your linear colors will be converted to sRGB space automatically. But how does this work with multiple rendertargets? I only want to do these corrections to the color textures and rendertarget, not to the normals, depth, specularity or whatever else I'll be rendering to my G-Buffer. Ok, so I just don't apply SRGBTexture = true; to my non-color textures, but when using SRGBWriteEnable = true; I'll do a gamma correction to all the values I write out to my rendertargets, no matter what I actually store there. I found some info on gamma over at Microsoft: http://msdn.microsoft.com/en-us/library/windows/desktop/bb173460%28v=vs.85%29.aspx For hardware that supports Multiple Render Targets (Direct3D 9) or Multiple-element Textures (Direct3D 9), only the first render target or element is written. If I understand correctly, SRGBWriteEnable should only be applied to the first rendertarget, but according to my tests it doesn't and is used for all rendertargets instead. Now the only alternative seems to be to handle these corrections manually in my shader and only correct the actual color output, but I'm not totally sure, that this'll not have any negative impact on color correctness. E.g. if the GPU does any blending or filtering or multisampling after the Linear-sRGB conversion... Do I even need gamma correction in this case, if I'm just writing texture color without lighting to my rendertarget? As far as I know, I DO need it because of the texture filtering and mip sampling happening in sRGB space instead, if I don't correct for it. Anyway, it'd be interesting to hear other people's solutions or thoughts about this.

• RPi and Java Embedded GPIO: Sensor Reading using Java Code

  - by hinkmond

  And, now to program the Java code for reading the fancy-schmancy static electricity sensor connected to your Raspberry Pi, here is the source code we'll use: First, we need to initialize ourselves... /* * Java Embedded Raspberry Pi GPIO Input app */ package jerpigpioinput; import java.io.FileWriter; import java.io.RandomAccessFile; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Calendar; /** * * @author hinkmond */ public class JerpiGPIOInput { static final String GPIO_IN = "in"; // Add which GPIO ports to read here static String[] GpioChannels = { "7" }; /** * @param args the command line arguments */ public static void main(String[] args) { try { /*** Init GPIO port(s) for input ***/ // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); for (String gpioChannel : GpioChannels) { System.out.println(gpioChannel); // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write(GPIO_IN); directionFile.flush(); } And, next we will open up a RandomAccessFile pointer to the GPIO port. /*** Read data from each GPIO port ***/ RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; int sleepPeriod = 10; final int MAXBUF = 256; byte[] inBytes = new byte[MAXBUF]; String inLine; int zeroCounter = 0; // Get current timestamp with Calendar() Calendar cal; DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss.SSS"); String dateStr; // Open RandomAccessFile handle to each GPIO port for (int channum=0; channum Then, loop forever to read in the values to the console. // Loop forever while (true) { // Get current timestamp for latest event cal = Calendar.getInstance(); dateStr = dateFormat.format(cal.getTime()); // Use RandomAccessFile handle to read in GPIO port value for (int channum=0; channum Rinse, lather, and repeat... Compile this Java code on your host PC or Mac with javac from the JDK. Copy over the JAR or class file to your Raspberry Pi, "sudo -i" to become root, then start up this Java app in a shell on your RPi. That's it! You should see a "1" value get logged each time you bring a statically charged item (like a balloon you rub on the cat) near the antenna of the sensor. There you go. You've just seen how Java Embedded technology on the Raspberry Pi is an easy way to access sensors. Hinkmond

• A view from the call center for the Nashville Flood telethon

  - by Rob Foster

  I want to break away from my usual topic of something technical and talk about what I experienced tonight while working in the call center for the Nashville Flood telethon, which was broadcast on WSMV, CNN, and The Weather Channel.  We started receiving calls about 7pm local time and to be honest, I had no idea what to expect when going into this.  I mean, I'm a pretty good talker, but this is different...We had a good script of what to say and how we were supposed to say it, as well as paper forms and pens that we used to collect information from people who wanted to donate their money to help.  I took my first few calls pretty easily and it went pretty quick and easy.  Everyone was upbeat and happy to be in the call center as well as people happy to be donating money. Pizza, snacks, and soft drinks were flowing well.  Everyone is smiling and happy.  :) About 3 or 4 calls into my night, I got a call from a lady that had lost 2 family members in West Nashville who drowned in the floods.  She was crying when she called and I of course tried to console her.  She told me how bad her situation was, losing family members and much of her neighborhood.  After all this, she still just wanted to help other people.  She was donating all the money that she could to the telethon and I want to share a direct quote from her: "I want to donate this instead of buying flowers for my family members' funeral because people out there need help.". Please let me pause while I get myself together <again>.  That caught me so off guard (and still does). I had kids calling wanting to donate their allowance, open their piggy banks, whatever they could do.  These are kids.  Kids not much older than my boys.  Kids who should be focused on buying the next cool video game or toy or whatever but wanted to do something.  Everyone just seemed to want to help. I took calls from as far away as British Columbia as well and pretty much coast to coast.  how cool is that? Yet another thing that caught me off guard.  This kind lady that called from British Columbia told me how much she loved visiting Nashville and just hated to see this happen.  I belive that she said that she will be attending the CMA Fest this year too.  I was sure to tell her not to cancel her plans!  :) It felt like every call I took (and I took A LOT, as did everyone else) was very personal and heartfelt.  I've never had the privelage to do anything like this and fell lucky to have been able to help out with answering phones and logging donations.  Nashville will bounce back very quickly, people are out there day and night helping each other, and the spirits are very high here.  I hope that one day, my kids read this blog and better understand who they are, where they come from, and what the human spirt is and can be.  I love this city, I love the people here, I love the culture and even more than ever am proud to say that this is me.  This is us.  We are Nashville!

• SSIS and StreamInsight Working Together.

  I have been thinking a lot recently about what it would be like to have StreamInsight and SSIS working together.  Well the CAT team have produced a paper on some of our options here. Here are some of my thoughts. There is of course a slight mismatch in their types of usage.  StreamInsight is an Event Stream processing engine capable of operating on new data in the sub second timeframe.  The engine allows you to do real time analytics and take decisions on events that have potentially only just happened.  SSIS on the other hand is a batch processing engine.  In general I do not like having to invoke the same package more than once every 90 seconds or so as it can start to get expensive.  Usually when doing batch processing we have an hour or longer of grace before we have to move data from A –> B. StreamInsight operates on streams of data.  Before anyone mentions it yes I know StreamInsight is equally adept at using the IEnumerable interface, but I would argue live streaming and real-time analytics is a primary goal of the product.  SSIS does not have an “Always On” button I do not like the idea of embedding StreamInsight inside SSIS using a transform particularly.  It means StreamInsight becomes a batch processing engine because it can only operate when the SSIS package is running and SSIS is in charge of when that happens. If I am to have StreamInsight within SSIS then I prefer to have StreamInsight on the adapters.  This way you can force the adapters to stay open and introduce events into your Pipeline.   SSIS has a much richer set of transforms out of the box than StreamInsight.  Although “Always On” was not a design goal of SSIS I have used it like this and it works just fine. SSIS being called from within StreamInsight, now that excites me.  see below   For a while now I have been thinking what it would be like to decouple the Data Flow task from the SSIS package and expose it as something with which you can interact.  Anything can instantiate this version of a DFT as it would expose one or more  input interfaces and one or more output interfaces.  I can imagine that this would be a big hit when moving to “The Cloud” as well.  I could see the Data Flow task maybe being hosted in Azure Appfabric or some such layer. StreamInsight would be able to take advantage of this as well.   I am interested to see where this goes and will be pressing for more meat around the subject when I visit Redmond soon.

• Log Debug Messages without Debug Serial on Shipped Device

  - by Kate Moss' Open Space

  Debug message is one of the ancient but useful way for problem resolving. Message is redirected to PB if KITL is enabled otherwise it goes to default debug port, usually a serial port on most of the platform but it really depends on how OEMWriteDebugString and OEMWriteDebugByte are implemented. For many reasons, we don't want to have a debug serial port, for example, we don't have enough spare serial ports and it can affect the performance. So some of the BSP designers decide to dump the messages into other media, could be a log file, shared memory or any solution that is suitable for the need. In CE 5.0 and previous, OAL and Kernel are linked into one binaries; in the other word, you can use whatever function in kernel, such as SC_CreateFileW to access filesystem in OAL, even this is strongly not recommended. But since the OAL is being a standalone executable in CE 6.0, we no longer can use this back door but only interface exported in NKGlobal which just provides enough for OAL but no more. Accessing filesystem or using sync object to communicate to other drivers or application is even not an option. Sounds like the kernel lock itself up; of course, OAL is in kernel space, you can still do whatever you want to hack into kernel, but once again, it is not only make it a dirty solution but also fragile. So isn't there an elegant solution? Let's see how a debug message print out. In private\winceos\COREOS\nk\kernel\printf.c, the OutputDebugStringW is the one for pumping out the messages; most of the code is for error handling and serialization but what really interesting is the following code piece     if (g_cInterruptsOff) {         OEMWriteDebugString ((unsigned short *)str);     } else {         g_pNKGlobal->pfnWriteDebugString ((unsigned short *)str);     }     CELOG_OutputDebugString(dwActvProcId, dwCurThId, str); It outputs the message to default debug output (is redirected to KITL when available) or OAL when needed but note that highlight part, it also invokes CELOG_OutputDebugString. Follow the thread to private\winceos\COREOS\nk\logger\CeLogInstrumentation.c, this function dump whatever input to CELOG. So whatever the debug message is we always got a clone in CELOG. General speaking, all of the debug message is logged to CELOG already, so what you need to do is using celogflush.exe with CELZONE_DEBUG zone, and then viewing the data using the by Readlog tool. Here are some information about these tools CELOG - http://msdn.microsoft.com/en-us/library/ee479818.aspx READLOG - http://msdn.microsoft.com/en-us/library/ee481220.aspx Also for advanced reader, I encourage you to dig into private\winceos\COREOS\nk\celog\celogdll, the source of CELOG.DLL and use it as a starting point to create a more lightweight debug message logger for your own device!

  If you find that you have a need to created multiple Custom Functoids you may also choose to create a Custom Functoid Library - a single project containing many custom functoids.  As previsouly discussed, the Custom Functoid Wizard can be used to create a project with a new custom functoid inside.  But what if you want to extend this project to include more custom functoids and create your Custom Functoid Library?  First create a Custom Functoid Library project and your first Custom Functoid using the Custom Functoid Wizard. When you open your Custom Functoid Library project in Visual Studio you will see that it contains your custom functoid class file along with its resource file.  One of the items this resource file contains is the ID of the the custom functoid.  Each custom functoid needs a unique ID that is over 6000.  When creating a Custom Functoid Library I would first suggest that you delete the ID from this resource file and instead create a _FunctoidIDs class containing constants for each of your custom functoids.  In this way you can easily see which custom functoid IDs are assigned to which custom functoid and which ID is next in the sequence of availability: namespace MyCompany.BizTalk.Functoids.TestFunctoids {     class _FunctoidIDs     {         public const int TestFunctoid                       = 6001;     } } You will then need to update the base() function in your existing functoid class to reference these constant values rather than the current resource file. From:    int functoidID;    // This has to be a number greater than 6000    functoidID = System.Convert.ToInt32(resmgr.GetString("FunctoidId"));    this.ID = functoidID; To: this.ID = _FunctoidIDs.TestFunctoid; To create a new custom functoid you can copy the existing custom functoid, renaming the resultant class file as appropriate.  Once it is renamed you will need to change the Class name, ResourceName reference and Base function name in the class code to those of your new custom functoid.  You will also need to create a new constant value in the _FunctoidIDs class and update the ID reference in your code to match this.  Assuming that you need some different functionalty from your new  customfunctoid you will need to check or amend the following in your functoid class file: Min and Max connections Functoid Category Input and Output connection types The parameters and functionality of the Execute function To change the appearance of you new custom functoid you will need to check or amend the following in the functoid resource file: Name Description Tooltip Exception Icon You can change the String values by double clicking the resource file and amending the value fields in the string table. To amend the functoid icon you will need to create a 16x16 bitmap image.  Once you have saved this you are then ready to import it into the functoid resource file.  In Visual Studio change the resource view to images, right click the icon and choose import from file. You have now completed your new custom functoid and created a Custom Functoid Library.  You can test your new library of functoids by building the project, copying the resultant DLL to C:\Program Files\Microsoft BizTalk Server 2009\Developer Tools\Mapper Extensions and then resetting the toolbox in Visual Studio.

• Macbook (non-pro, late 2010) Power Management Issues relating to Nvidia-Current drivers

  - by gbvitaobscura

  I have tried many potential solutions but to no avail! (this is going to be a long post) Essentially, when I first install ubuntu (I have tested 10.11-12.04 beta) I can change the brightness of the macbook backlight. One of the first things I usually do once my machine finishes installing is enter "sudo apt-get install nvidia-current" into the terminal to get my Nvidia graphics card set up. Before I install nvidia-current power management works flawlessly. After installing nvidia-current my graphics driver works mostly properly (more on that later). When I press F1 or F2 notify osd pops up and shows icon for the backlight along with a meter which changes according to how much I press F1 or F2, but the backlight does not change brightness at all. Two supplementary facts: when I am running off of battery power the backlight does not dim ever, also changing the backlight brightness through the terminal does not work (it recognizes the command but changes nothing). Things which did not work: 1. editing xorg.conf 2. python script/hack 3. editing grub Things which did work: 1. removing Nvidia-Current Final piece of information: Although my graphics card works in every way but Power Management it can not be found through System Settings/Details (Graphics Unknown) I'm using the NVIDIA GeForce 320M. the output of lspci is: 00:00.0 Host bridge: NVIDIA Corporation MCP89 HOST Bridge (rev a1) 00:00.1 RAM memory: NVIDIA Corporation MCP89 Memory Controller (rev a1) 00:01.0 RAM memory: NVIDIA Corporation Device 0d6d (rev a1) 00:01.1 RAM memory: NVIDIA Corporation Device 0d6e (rev a1) 00:01.2 RAM memory: NVIDIA Corporation Device 0d6f (rev a1) 00:01.3 RAM memory: NVIDIA Corporation Device 0d70 (rev a1) 00:02.0 RAM memory: NVIDIA Corporation Device 0d71 (rev a1) 00:02.1 RAM memory: NVIDIA Corporation Device 0d72 (rev a1) 00:03.0 ISA bridge: NVIDIA Corporation MCP89 LPC Bridge (rev a2) 00:03.1 RAM memory: NVIDIA Corporation MCP89 Memory Controller (rev a1) 00:03.2 SMBus: NVIDIA Corporation MCP89 SMBus (rev a1) 00:03.3 RAM memory: NVIDIA Corporation MCP89 Memory Controller (rev a1) 00:03.4 Co-processor: NVIDIA Corporation MCP89 Co-Processor (rev a1) 00:04.0 USB controller: NVIDIA Corporation MCP89 OHCI USB 1.1 Controller (rev a1) 00:04.1 USB controller: NVIDIA Corporation MCP89 EHCI USB 2.0 Controller (rev a2) 00:06.0 USB controller: NVIDIA Corporation MCP89 OHCI USB 1.1 Controller (rev a1) 00:06.1 USB controller: NVIDIA Corporation MCP89 EHCI USB 2.0 Controller (rev a2) 00:08.0 Audio device: NVIDIA Corporation MCP89 High Definition Audio (rev a2) 00:09.0 Ethernet controller: NVIDIA Corporation MCP89 Ethernet (rev a1) 00:0a.0 IDE interface: NVIDIA Corporation MCP89 SATA Controller (rev a2) 00:0b.0 RAM memory: NVIDIA Corporation Device 0d75 (rev a1) 00:15.0 PCI bridge: NVIDIA Corporation Device 0d9b (rev a1) 00:17.0 PCI bridge: NVIDIA Corporation MCP89 PCI Express Bridge (rev a1) 01:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01) 02:00.0 VGA compatible controller: NVIDIA Corporation Device 08a0 (rev a2) There is a very similar bug on Launchpad which I have posted below. https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/764195

• How to recover from finite-state-machine breakdown?

  - by Earl Grey

  My question may seems very scientific but I think it's a common problem and seasoned developers and programmers hopefully will have some advice to avoid the problem I mention in title. Btw., what I describe bellow is a real problem I am trying to proactively solve in my iOS project, I want to avoid it at all cost. By finite state machine I mean this I have a UI with a few buttons, several session states relevant to that UI and what this UI represents, I have some data which values are partly displayed in the UI, I receive and handle some external triggers (represented by callbacks from sensors). I made state diagrams to better map the relevant scenarios that are desirable and alowable in that UI and application. As I slowly implement the code, the app starts to behave more and more like it should. However, I am not very confident that it is robust enough. My doubts come from watching my own thinking and implementation process as it goes. I was confident that I had everything covered, but it was enough to make a few brute tests in the UI and I quickly realized that there are still gaps in the behavior ..I patched them. However, as each component depends and behaves based on input from some other component, a certain input from user or some external source trigers a chain of events, state changes..etc. I have several components and each behave like this Trigger received on input - trigger and its sender analyzed - output something (a message, a state change) based on analysis The problem is, this is not completely selfcontained, and my components (a database item, a session state, some button's state)...COULD be changed, influenced, deleted, or otherwise modified, outside the scope of the event-chain or desirable scenario. (phone crashes, battery is empty phone turn of suddenly) This will introduce a nonvalid situation into the system, from which the system potentially COULD NOT BE ABLE to recover. I see this (althought people do not realize this is the problem) in many of my competitors apps that are on apple store, customers write things like this "I added three documents, and after going there and there, i cannot open them, even if a see them." or "I recorded videos everyday, but after recording a too log video, I cannot turn of captions on them.., and the button for captions doesn't work".. These are just shortened examples, customers often describe it in more detail..from the descriptions and behavior described in them, I assume that the particular app has a FSM breakdown. So the ultimate question is how can I avoid this, and how to protect the system from blocking itself? EDIT I am talking in the context of one viewcontroller's view on the phone, I mean one part of the application. I Understand the MVC pattern, I have separate modules for distinct functionality..everything I describe is relevant to one canvas on the UI.

• What is the SharePoint Action Framework and Why do I need it ?

  - by SAF

  For those out there that are a little curious as to whether SAF is any use to your organisation, please read this FAQ.  What is SAF ? SAF is free to use. SAF is the "SharePoint Action Framework", it was built by myself and Hugo (plus a few others along the way). SAF is written entirely in C# code available from : http://saf.codeplex.com.   SAF is a way to automate SharePoint configuration changes. An Action is a command/class/task/script written in C# that performs a unit of execution against SharePoint such as "CreateWeb"  or "AddLookupColumn". A SAF Macro is collection of one or more Actions. SAF Macro can be run from Msbuild, a Feature, StsAdm or common plain old .Net code. Parameters can be passed to a Macro at run-time from a variety of sources such as "Environment Variable", "*.config", "Msbuild Properties", Feature Properties, command line args, .net code. SAF emits lots of trace statements at run-time, these can be viewed using "DebugView". One Action can pass parameters to another Action. Parameters can be set using Expression Syntax such as "DateTime.Now".  You should consider SAF is you suffer from one of the following symptoms... "Our developers write lots of code to deploy changes at release time - it's always rushed" "I don't want my developers shelling out to Powershell or Stsadm from a Feature". "We have loads of Console applications now, I have lost track of where they are, or what they do" "We seem to be writing similar scripts against SharePoint in lots of ways, testing is hard". "My scripts often have lots of errors - they are done at the last minute". "When something goes wrong - I have no idea what went wrong or how to solve it". "Our Features get stuck and bomb out half way through - there no way to roll them back". "We have tons of Features now - I can't keep track". "We deploy Features to run one-off tasks" "We have a library of reusable scripts, but, we can only run it in one way, sometimes we want to run it from MSbuild and a Feature". "I want to automate the deployment of changes to our development environment". "I would like to run a housekeeping task on a scheduled basis"   So I like the sound of SAF - what's the problems ?  Realistically, there are few things that need to be considered: Someone on your team will need to spend a day or 2 understanding SAF and deciding exactly how you want to use it. I would suggest a Tech Lead, SysAdm or SP Architect will need to download it, try out the examples, look through the unit tests. Ask us questions. Although, SAF can be downloaded and set to go in a few minutes, you will still need to address issues such as - "Do you want to execute your Macros in MsBuild or from a Feature ?" You will need to decide who is going to do your deployments - is it each developer to themself, or do you require a dedicated Build Manager ? As most environments (Dev, QA, Live etc) require different settings (e.g. Urls, Database names, accounts etc), you will more than likely want to define these and set a properties file up for each environment. (These can then be injected into Saf at run-time). There may be no Action to solve your particular problem. If this is the case, suggest it to us - we can try and write it, or write it yourself. It's very easy to write a new Action - we have an approach to easily unit test it, document it and author it. For example, I wrote one to deploy  a WSP in 2 hours the other day. Alternatively, Saf can also call Stsadm commands and Powershell scripts.   Anyway, I do hope this helps! If you still need help, or a quick start, we can also offer consultancy around SAF. If you want to know more give us a call or drop an email to [email protected]

• Creating a new naming context in OUD

  - by Sylvain Duloutre

  A naming context (also known as a directory suffix) is a DN that identifies the top entry in a locally held directory hierarchy. A new naming context can be created using ODSM, the OUD gui admin console, as described in http://docs.oracle.com/cd/E29407_01/admin.111200/e22648/server_config.htm#CBDGCJGF It can also be created using the dsconfig command lione as described below: Creation of a new naming context consists in 3 steps: First create a Local Backend Workflow element (myNewDb in this exemple) ,  responsible for the naming context base dn, e.g o=example. dsconfig create-workflow-element \           --set base-dn:o=example \           --set enabled:true \           --type db-local-backend \           --element-name myNewDb \           --hostname <your host> \           --port <admin port> \           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Second, create a Workflow element (workFlowForMyNewDb in this exemple) associated with the Local Backend Workflow element. WorkFlow elements are used to route LDAP requests to the appropriate database, based on the target base dn. dsconfig create-workflow \           --set base-dn:o=example \           --set enabled:true \           --set workflow-element:myNewDb \           --type generic \           --workflow-name workFlowForMyNewDb \           --hostname <your host name> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Then, the workflow element must be made visible outside of the directory, i.e added to the internal "routing table". This is done by adding the Workflow to the appropriate Network Group. A Network group  is used to classify incoming client connections and route requests to workflows. dsconfig set-network-group-prop \           --group-name network-group \           --add workflow:workFlowForMyNewDb \           --hostname <your hostname> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt At that stage, it is possible to import entries to the new naming context o=example.

• Web Application Integration Steps in OAM 11gR2 (High Level)

  - by Venkata Srikanth

  Install OAM, Webtier (OHS) and WebGate as per the standard installation steps. Create a WebGate instance (i.e deploy WebGate) A WebGate instance must be created that will copy required bits of agent from WEBGATE_HOME to WebGate instance location that shares the same INSTANCE_HOME with OHS ./deployWebGateInstance.sh –w /Oracle/Middleware/Oracle_WT1/instances/instance1/config/ohs1 –oh /Oracle/Middleware/Oracle_OAMWebGate1 Note: Here –w flag indicates OHS instance folder and –oh indicates the WebGate Oracle home Configure WebGate In the webgate configuration the EditHttpdConf utility will copy OUI instantiated apache_webgate.template from WEBGATE_HOME to webgate instance location (renamed to webgate.conf), and update httpd.conf with one additional line to include webgate.conf. export LD_LIBRARY_PATH=$ LD_LIBRARY_PATH:/Oracle/Middleware/Oracle_WT1/lib Navigate to /Oracle/Middleware/Oracle_OAMWebGate1/webgate/ohs/tools/setup/InstallTools ./EditHttpdConf –w /Oracle/Middleware/Oracle_WT1/instances/instace1/config/OHS/ohs1 –oh /Oracle/Middleware/Oracle_OAMWebGate1 –o webgate.conf Register WebGate Use RREG tool to register the OAM 11G WebGate Navigate to /Oracle/Middleware/Oracle_IDM1/oam/server/rreg/input Edit OAM11Grequest.xml. Change the specific xml content to include the weblogic admin URL, agentBaseURL, host identifier etc.. Navigate to /Oracle/Middleware/Oracle_IDM1/oam/server/rreg/bin Set permissions to oamreg.sh à chmod 777 oamreg.sh Edit oamreg.sh and set OAM_REG_HOME=/Oracle/Middleware/Oracle_IDM1/oam/server/rreg ./oamreg.sh inband input/OAM11Grequest.xml Enter the WebLogic admin credentials when prompted. After performing the above steps, there will be two artifcats created under Oracle/Middleware/Oracle_IDM1/oam/server/rreg/output, namely ObAccessClient.xml (Stroing webgate config parameters) and cwallet.sso (storing the agent key). These files must be copied to WebGate instance config folder (/Oracle/Middleware/Oracle_WT1/instances/instance1/config/ohs1/webgate/config) Restart OHS Deploy the web application (myApp) in WebLogic application server Proxy Configuration in OHS The mod_wl_ohs module enables requests to be proxied from Oracle HTTP Server 11g to Oracle WebLogic Server. Navigate to /Oracle/Middleware/Oracle_WT1/instances/instance1/config/OHS/ohs1 Edit mod_wl_ohs.conf file to include the following: <IfModule weblogic_module> WebLogicHost <WEBLOGIC_HOST> WebLogicPort <WEBLOGIC_PORT> # Debug ON # WLLogFile /tmp/weblogic.log MatchExpression *.jsp </IfModule> <Location /myApp> SetHandler weblogic-handler # PathTrim /weblogic # ErrorPage http:/WEBLOGIC_HOME:WEBLOGIC_PORT/ </Location> Note: Here WEBLOGIC_HOST and WEBLOGIC_PORT are the WebLogic admin server host and port respectively Restart OHS. Now if we access the web application URL with OHS host and port (Ex: http://OHS_HOST:<OHS_PORT>/myApp) so that the requests will be proxied to WebLogic server. Create a new application domain Login to OAM Admin Console Navigate to Shared Componentsà Authentication Schemesà Create Authentication Scheme (Ex: LDAP Auth Scheme. Here the scheme is assoicated with LDAP Authentication Module) Navigate to Policy Configuration à Application Domain à Create Application Domain Enter the Application Domain Name and Click Apply. Navigate to Resources tab and add the resource urls (Web Application URLs that needs to be protected) Navigate to Authentication Policy tab à Create a new authentication ploicy by providing the Resource URLs (The sample Web Application URLs) and Authentication Scheme. Navigate to Authorization Policy tab à Create a new authorization policy à Enter authorization policy name and navigate to Resource Tab à Attach the Reource URL, Host Identifiers here. Navigate to Conditions tab à Add the conditions like whom to allow and whom to deny access. Navigate to Rules tab à Crate the Allow Rule and Deny Rule with the available conditions from the previous step so that the Authorization Policy may authorize the logins. Navigate to Resources tab and attach the Authentication and Authorization plocies created in the above steps. Test the Web Application Integration.

• WebLogic Server–Use the Execution Context ID in Applications–Lessons From Hansel and Gretel

  - by james.bayer

  I learned a neat trick this week.  Don’t let your breadcrumbs go to waste like Hansel and Gretel did!  Keep track of the code path, logs and errors for each request as they flow through the system.  Earlier this week an OTN forum post in the WLS – General category by Oracle Ace John Stegeman asked a question how to retrieve the Execution Context ID so that it could be used on an error page that a user could provide to a help desk or use to check with application administrators so they could look up what went wrong.  What is the Execution Context ID (ECID)?  Fusion Middleware injects an ECID as a request enters the system and it says with the request as it flows from Oracle HTTP Server to Oracle Web Cache to multiple WebLogic Servers to the Oracle Database. It’s a way to uniquely identify a request across tiers.  According to the documentation it’s: The value of the ECID is a unique identifier that can be used to correlate individual events as being part of the same request execution flow. For example, events that are identified as being related to a particular request typically have the same ECID value.  The format of the ECID string itself is determined by an internal mechanism that is subject to change; therefore, you should not have or place any dependencies on that format. The novel idea that I see John had was to extend this concept beyond the diagnostic information that is captured by Fusion Middleware.  Why not also use this identifier in your logs and errors so you can correlate even more information together!  Your logging might already identify the user, so why not identify the request so you filter down even more.  All you need to do inside of WebLogic Server to get ahold of this information is invoke DiagnosticConextHelper: weblogic.diagnostics.context.DiagnosticContextHelper.getContextId() This class has other helpful methods to see other values tracked by the diagnostics framework too.  This way I can see even more detail and get information across tiers. In performance profiling, this can be very handy to track down where time is being spent in code.  I’ve blogged and made videos about this before.  JRockit Flight Recorder can use the WLDF Diagnostic Volume in WLS 10.3.3+ to automatically capture and correlate lots of helpful information for each request without installing any special agents and with the out-of-the-box JRockit and WLS settings!  You can see here how information is displayed in JRockit Flight Recorder about a single request as it calls a Servlet, which calls an EJB, which gets a DB connection, which starts a transaction, etc.  You can get timings around everything and even see the SQL that is used. http://download.oracle.com/docs/cd/E21764_01/web.1111/e13714/using_flightrecorder.htm#WLDFC480 Recent versions of the WLS console also are able to visualize this data too, so it works with other JVMs besides JRockit when you turn on WLDF instrumentation. I wrote a little sample application that verified to myself that the ECID did actually cross JVM boundaries.  I invoked a Servlet in one JVM, which acted as an EJB client to Stateless Session Bean running in another JVM.  Each call returned the same ECID.  You need to turn on WLDF Instrumentation for this to work otherwise the framework returns null.  I’m glad John put me on to this API as I have some interesting ideas on how to correlate some information together.
