JTableCombo sample and jbo-34004

9i jdeveloper version : 9.0.3.1
When running the sample from http://otn.oracle.com/sample_code/products/jdev/jclient/jclient_table_combo_sample.html
in JDev 9.0.3.1, the following exception is thrown when attempting to change the location:
oracle.jbo.JboException: 34004
What can we do to avoid this error?
thanks,
Bert.

Grant,
You need the fix to Bug#2632152.
We are testing a patch set that includes this fix now, but I've emailed a spot-patch to other folks who have hit this issue. If you email me at [email protected] I will send the small JAR file to you as an attachment in the interim.
Thanks.

JBO-30003 and JBO-25019

We get JBO-30003 and JBO-25019 when calling oracle.jbo.common.ampool.ApplicationPoolImpl.useApplicationModule() with multiple (16) user sessions. I cannot duplicate the problem in my development/test/debug environment. We are using OC4J 9.0.2.0.0 (production version), Oracle9i JDeveloper 9.0.2.829, and Oracle RDBMS 8.1.7.1.1 on Windows 2000. I looked up the JBO error messages, but still cannot see the cause.
Any help would be greatly appreciated. Thank you.

Hi,
The exception stack indicates that BC4J had a problem faulting in the value of the PerSystemId attribute of the Person. BC4J was faulting in (from DB) this attribute value during ViewObject passivation. This means that BC4J believed that there was a new ViewRow which referred to this entity. The primary key of this Person entity instance was null so fault-in failed. Of course this is all very strange because it appears as if the PerSystemId is the PK!
I tried to reproduce this in a simple dept testcase in 9.0.3 without success. I did get a similar, not the same, exception stack in BC4J 9.0.2.799 with the following sample code:
import oracle.jbo.ViewObject;
import oracle.jbo.ApplicationModule;
import oracle.jbo.Row;
import oracle.jbo.client.Configuration;
     ApplicationModule am =   Configuration.createRootApplicationModule(
        "mypackage1.Mypackage1Module"
        , "Mypackage1ModuleLocal"
        , null);
     ViewObject vo = am.findViewObject("DeptView");
     Row row = vo.createRow();
     vo.insertRow(row);
     // simulate a passivation -- occurs during managed
     // state ApplicationModule release.
     int id = am.passivateState(null);

Hello.... I already loaded logic 9 on my laptop hard drive... I would to load all the samples and loops on an external drive... Do I need to reinstall from DVD's or can I drag and drop?

Hello.... I already loaded logic 9 on my laptop hard drive... I would to load all the samples and loops on an external drive... Do I need to reinstall from DVD's or can I drag and drop?

Thank you.... Would you know where they would be on my hard dive? Are they all together?

Is there any way to have a COMPLETE list of all samples and loops ( Logic 8

I'm sure it's been posted previously, but anyway, I'm looking to buy new Apple Loops libraries and I have faced the fact , that many of the sounds and loops produced by third parties manufacturers have been already included in Logic installation discs.
I have a list of Apple Loops DVD's that have been included with Logic somewhere, the problem is, Apple didn't post ( I believe) the credits of all 3rd party manufacturers that have produced these libraries that are included with Logic or Garage band. Is there any way to have a COMPLETE list of all samples and loops that are included with Apple DAW's so I wouldn't duplicate anything ? I'm pretty much positive that Apple had other companies to sound design and sample all libraries for them, so is there also a way to have a list of those manufacturers? Again, the objection is to start upgrading the sound library without any possible duplication?
Thanks in advance!

Chris, I certainly don't mind additional questions and postings.
I believe there are many issues with Apple Loops and Logic that need to be resolved and people need to be aware of that. Unfortunately, in opposite to the old "german" version of Logic , there's no lifetime tech support, you can't even call and ask the question after 60 days , which isn't right for a professional software of this level, especially considering the fact that many things still remain vague in Logic even for developers and tech support people!( believe me, I've called and asked!)
Issues like that need to be resolved over the phone with the company, period!
One thing I also learned over the years as a Mac OSX user, if something doesn't work, don't mess with it. Delete your drive and re-install everything. This is very frustrating , I know, but unfortunately this is the only way to deal with OSX issues, if you got a problem with your system, don't try to fix it. It's never gonna be the same again. I know , it's off the topic a little bit, but if your content is missing from the system files, before installing your new Logic, back up your important files, wipe up your drive and clean install Mac OSX , run updates and then install the Logic. Most likely , everything will be in it's place, at least 90% or more. I gave up trying to make two system in my house to be compatible 100% , but it's OK if they're 90% or more identical. I spent enormous amount of time trying to find out what's missing and where, I visited most of the forums and there's no clean answer.

How to output sample and convert clocks to PFI lines of E-Series DAQ (DAQPad-6015)

Hi,
Can someone tell me how to output sample and convert clocks to PFI lines of E-Series DAQ (DAQPad-6015)?
Thank you very much.
Jack

John --
Windows is not an option for me. I like your idea of using a counter output -- it may be helpful as I am getting ramped up, but my application will eventually require both timer outputs.
I have a legacy C application written for Macintosh, and I am in the process of moving it onto OS X. So my options are to use DAQmx Base, or write an in-kernel driver. I actually have already done the latter for 6024/6025 E-series boards (for another company); for this client I was hoping to use the DAQmx Base to allow an easy transition to M-series boards, without the cost of writing and supporting a low-level driver.
The specific task I am doing is relatively straightforward. I record 2 channels of AI for a short period (usually about 250 ms.) and during this time I drive 2 external digital signals. Right now, I use the 2 timer outputs, which allows precise synchronization with the output and AI sampling.
I appreciate your comments, and thanks in advance for any additional suggestions you can lob my way.

Help required for sample and Hold

Hello,
I am working on a project Cerebral Oxygenation Monitoring. The concept is similar to pulse oximetry. I help already developed the hardware that includes the timing circuit , led driver for driving Red and IR Led, Amplifier and Filter Stage. I am getting the pulse signal but it is multiplexed signal corresponding to effect of both Red/IR Led. Now to separate it I need to use sample and hold circuit, whihc I can achieve with and IC LF398 but I want to minimise this part and directly take this multiplexed signal through DAQ Card in to LabVIEW and further create sample and hold in LabVIEW.
The sampling needs to be in synchronus with the Timing signal given to Red and IR. How I can achieve this in LabVIEW.
For eg: the Red Led is triggered with a pulse of 1 ms with a repeatation rate after 10 ms. So this timing pulse should trigger the sampling part.
Please Help.

CoastalMaineBird wrote:
Not sure what you need the HOLD part for.
Correct me if I'm wrong:
You have a 1 mSec pulse, every 10 mSec.
Each pulse triggers two LEDs: RED and IR
You have a single signal which contains the processed (through the body, or whatever) responses to BOTH of those signals.
So, how does a S&H, hardware or otherwise, separate the two responses?
Is one delayed in time, relative to the other?
YES you are right, 1 mSec pulse, every 10 mSec.
Above figure shows the trigger pulses generated using standard hardware. One triggers IR and other triggers RED. In above case I had kept repetation rate 4msec
This is the signal which I may get
Now how do I separate both of these signals in LabVIEW

Hello, I have a 5min. part of a piece of meditation music (I think its from the 1970-80s) is there a website that can upload my sample and tell me who it is ? I want to get a new version....Thanks

Well... it's not actually an iTunes or even an Apple question is it? But you can use either Shazam or Soundhound.
If you do a search for both of them, you will find the various options available to you, which include apps for portable devices and in the case of Shazam, a work-round that allows you to use an online option using your computer's microphone on either a PC or Mac.
There may be other services as well, but I know these two.
I do not receive any reward (financial or otherwise) as a result of mentioning either Shazam or Soundhound.

Since upgrading to OSx 10.9, I cannot place my music for iPhoto slideshows. The only music that works is the Sample and Theme music that comes with iPhoto. Any idea of what to do about this problem?

In iTunes go File -> Library -> Organise Library -> Reorganise Library.
Then quit and restart iPhoto.

Can anybody explain me how to sample and play audio files with logic's EXS2

can anybody explain me how to sample and play audio files with logic's EXS24 Sampler???
i cant find a way to upload and manage my own audio content on this sampler...

i uderstand , thanx...
i managed to open an audio file and placed it in the sampler,i can play t sample in the little keyboard in the zones section, howver i dont know how to play it with my controller... the sample shows in C1 on logic's keyboard but if i play C1 on my controller nothing happens... how can i fix this?
Also, i noticed the sample plays from beginning to end once i click on it, how do i do to just make it last until i release the key? like a logic sound??? (in case i want to play a small portion of the sample only)
Thanx

SSD: for OS and apps, or for samples and audio?

I'm thinking about adding a 256 gig solid state drive; I currently have two 1TB drives. I tend to use large sample-based instruments - Play, Ivory, Vienna, Kontakt, Omnisphere, etc. - but not particularly great track counts. If I used it as the startup disk, 256 gigs would be way more than enough (because audio and video files are on other disks.) As a sample disk it would hold my most demanding and most often used libraries.
What would be the most efficient use of that SSD speed - OS and apps, or streaming samples and audio?

Thanks for the recommendation on size. I found a great answer to my question about file locations at:
http://discussions.apple.com/message.jspa?messageID=12293000#12293000
Using the advanced Options (control click the active admin account) in the accounts pane in System Preferences, one can specify a new location for the home folder. Very practical and way easier than trying to go into all the app's libraries to tell them where their files are.
Now I can just copy my home folder to the internal drive, and delete it on the SSD. After a restart, this new location will be recognized as the correct home folder.

Sample and hold

Could you please help me in getting the sample and and hold (Or Peak and hold )functionality of any any given input using LABVIEW
Regards,
Sharanu

If Dennis has already answered your question, than you can disregard
this message. I got the sense that your question wasn't about the
"sample-and-hold" circuitry built into DAQ cards capable of
simultaneous sampling, but actually was a software question about
tracking and holding peak (or maximum) values that are coming in
through an analog input. If this is the case, please provide a little
more information about your program, and I'm sure we can help you out.

Sample and hold inputs on 6023e card

I am using a 6023E card and need to input 2 similiar channels into Labview and see the amplitude and phase differences. I have the program working for simulated inputs but the problem (according to NI) seems to be that the time delay in switching between channels causes the phase numbers to be wrong.
Has anyone used a sample and hold vi or something like it that will allow both signals to be read with respect to the same reference? I realize that there are better cards that will do this but this is a student lab and we need 16 of them so cost is a big problem.
Any suggestions would be appreciated.
Thanks
Dave

There are two ways of correcting for the multiplexing delay of your board.
- You can either use the method I suggested in your previous posting http://exchange.ni.com/servlet/Redirect?id=10455451 or
- You can re-align your signals so they are "in phase". To do so use the Align Waveforms VIs located in your Analyze>>Waveform Conditioning palette. The output of these VIs will be your time signals resampled so they are aligned. Check-out the example called "Correct for MIO inter-channel delay (continuous).vi". But, as mentioned, this method is "overkill" in your case. I'd recommend you to use the first method which is both faster and more accurate.

Sample and Hold Application.

I am acquiring data with the NI ELVIS on an analog input channel A0.
I need to sample and hold the data according to a 480 Hz (2.08 ms) clock as follows:
1. Acquire data for the 0.69 ms (1st third of the cycle) and place the data into a new waveform.
2. Acquire data from 0.69 ms to 1.39 ms (the 2nd third of the cycle) and place the data into a new waveform.
3. Acquire data from 1.39 ms to 2.08 ms (last third of the cycle) and place the data into a new waveform.
Currently, I have built a VI (attached) to generate two clock signals. The first clock signal turns on a red LED for 0.69ms then turns off for the rest of the cycle. The second clock signal turns on when the first clock signal transititions to a low state for the next 0.69 ms and remains off for the rest of the cycle. Both LED illumination signals are picked up by a photodetector, so this is why I need the sample and hold application explained above.
If you could help that would be great. My current VI is attached. Thanks so much!

Correct me if I'm wrong, you are turning on two LEDs in a pattern and reading the light level. You want to have three separate waveforms for the light reading, based on when the lights are turned on and off.
If this is the case, here is what I would try:
Trigger your analog input reading off of the turning on of the first LED. You might have to put an initial delay into your clock pulse (that turns on the first LED). This initial delay will insure that the LED is not turned on before the analog input has been started. Data collection will start when the first LED is turned on (the trigger) and will end after the appropriate amount of time. (You could end it in many ways; user presses a stop button, configure collection for a finite number of data points, final pulse has ended,..). After data collection is finished take the single waveform that is storing all of the light data and use the waveform functions in the Waveform palette to split it into your three waveform subsets.
I suppose another way to produce the three waveforms would be to wire your light sensor into three analog inputs, then configure three separate voltage inputs with appropriate triggers based on the turning on and off of the LEDs. CH 1 triggers when LED 1 is turned on, CH 2 triggers when the LED 1 is turned off, CH 3 is triggered when LED 2 is turned on.
I hope this is helpful in some way,
Sam

Sample-and-hold vi for USB-6251

I want to implement a sample-and-hold circuit on my USB-6251 device.
The input will be an analog voltage waveform. The output will be that same analog voltage waveform (this is the "sampling" in the sample and hold), with one caveat: I want to hold the output at a certain level depending upon a digital input (ttl 5V hi or 0V low). For example, when the digital input cycles hi, I want to take the value of the analog output at that point in time, and continue to output that voltage value until the digital input cycles back low (the "hold" in the sample and hold), at which point the output continues outputing the incoming analog voltage waveform.
I think I should be able to create such a VI using a comparison function, but I cannot quite figure out how to implement it. Any suggestions?
thanks!

I would imagine this could be accomplished with the use of a simple true false selector. In the false case the waveform coming from the Analog Read would be passed on and also into a shift register on the right side of the reading while loop. This shift register would then also be the true case of the selector. There would then be a producer consumer style structure where this output array would be fed into a DAQmx write.

EXS Factory Samples And Sampler Instruments Duplicates and Missing Legacy

since updating and comparing to my macbook which i havent updated, it seems there are missing exs factory samples. for example on new logic 9 there are 2 folders exs factory samples which have 01 through 09 folders. the sampler instruments folder has 01 through 12 and folder 12 legacy instruments which on my mac book in sampler instruments have 01 thru 10 then skips to 26 to 41
ann ex factory folder on mac book 01 thru 10 folders and 10 legacy folder contains 01 thru 10 then skips to 27 thru 38. what is going on . why are there missing files in new upgrade i did on main computer? and how do i get all the exs samples and what should they be?

This problem began,i think in Logic 8.....when you install LP8 normally the EXS instruments and Legacy EXS there were always some missing that I was used to using..I found them eventually,they were now part of the the Garageband instrument Library.
I went back and searched all the install DVDs until I found them showing up..some EXS instruments would be missing the actual samples which were now part of the Garageband instrument library,Attitude Bass being one I remember off hand.
I just copied all the Instruments and samples I needed and got rid of the rest which amounts to a lot of space being freed up.
Now I just keep a backup of all my EXS files on external drive so I dont need to install them every upgrade as in Logic 9 (which I checked just in case there were any new files etc!)..which also sorts out the duplicate files headache.
Hope this helps.....
