Export journalized data in real time

Hello,
I must pull journalized data in real time out of Oracle DB source.
my package has ODIWaiForData operator and interface which triggers only in case of Journalized Data in my source table. Interface loads data to target Oracle table in real time and it works.
Is it possible to send Journalized Data out of Oracle database in real time? Maybe some insert/update statements within sql file, csv file or through ODIOSCommand operator somehow?

Oracle Data Integrator - Real Time Integration

Hi,
I want to know that, is there any possibility of integrating data in real-time using Oracle Data Integrator?
If yes, does it affect the OLTP system performance? (Could it read from db logs,etc..)
Thanks..

Using ODI with Logminer-based CDC will affect performance on the source system more than using Oracle Goldengate, let me explain why:
When using the ODI Logminer-based Journalisation the Logminer functionality will move the primary-key of the affected row into the journal table. When you are then ready to move the changed data, running an interface to move the data reads the Journal-view, which joins the journal table (primary keys) to the source data (and dealing with deleted rows), optimising out duplicate rows in order to bring across the then-current state of the data, which can then be loaded into the target system, on completion, the moved rows can be removed from the journal table. The data will appear in the journal table as soon as Logminer puts it there, which may be a lag of up to two minutes using asynchronous setting, whereas Synchronous Logminer applies "system triggers to the table, with the consequent overhead.
With Oracle Goldengate, the comitted transactions are read from the log as soon as the log-writer puts the commit into the log. All the data is picked up from the log, at that point. It is then written to the trail-file system of Oracle Goldengate which can be propogated to multiple other systems potentially with sub-second latency, and minimal impact on the source system due to the efficient reading and writing mechanisms. One other consequence of using Oracle Goldengate is that you get every change of the data, not the optimised then-current state of the data when moved.
Hope this explanation helps.

Read data in real time and save as an excel file

Hi,
I want to write a LabVIEW progarmme which able to read data in real time and save it as an excel file from Varian Vacuum muli-gauge.
It is using RS232 port.
Can anyone give me some examples or point me in the right direction?
I am a beginner of LabVIEW. Hope anyone can help me.
Thank you very much!!
Joanne

Thanks for your reply.
I just use MAX to verify that the rs232 port is operational.
However, there is an error (please refer to the attachment).
One possible reason is in MAX I am trying to do the default command *idn? ...but it doesn't work.
I read the vacuum multi-gauge manual but I don't know which command should I use...
I attached the manual and can you tell me which command should I use?
Or can you tell me other possible reason for this error code?
Thank you very much.
Joan

Viewing data in real-time and saving on-demand - USB4000 Spectrometer

Hey,
I am trying to create a program with a USB4000 Fiber Optic Spectrometer to allow the user to view the data in real-time on the front-panel, yet to be implemented, and also be able to save the data to an excel datasheet, or if another format if more appropriate. I am reasonably new to LabVIEW and have limited experience with saving data to excel.
I am currently trying to build upon one of the example VIs given with the drivers. Currently the VI produces data like the following:
Wavelength (nm) Spectrum Data
xyz xyz
xyz xyz
xyz xyz
xyz xyz
I want my VI to continue to append to a new column every iteration but I think due to me inputting an array of dimension size 2 it can't but am unsure how to get around this?
The current VI starts off by creating the Headers and then appending to insert the spectrometer Data.
Any help would be much appreciated, apologies if I am unclear about anything.

Ok, a couple comments. First, it is easier to build a 2D array by appending rows and then transposing the array before saving it. Also it is much more efficient to preallocate the array if you know how many columns the data is going to have.
Second, adding a new column or row isn't a problem because an additional column (or row) doesn't effect the number of dimensions.

HOW CAN I ACQUIRE AND DEPLOY DATA IN REAL TIME WITH DAQ 6024E?

HI ENGINEER,
I'M PROGRAMING AN APLICATION WHICH I NEED ACUIRING AND DEPLOYING AN ANALOGOUS SIGNAL IN REAL TIME.
I HAVE:
LabVIEW 7.0
WINDOWS 2000
DAQ CARD 6024E
THE SIGNAL I WANT TO ACQUIRE IS 0-10 Vcd FROM A SENSOR, THE PROBLEM I HAVE, IS THAT I AM ACQUIERING THE DATA AND IT SEEM THAT THEY ARE UPDATING EACH SECOND, BUT I HAVE BEEN MOVING THE PARAMETERS SUCH AS TASK TIMING IN THE DAQ ASSISTANT VI AND NOTHING HAPPENS.
CAN YOU TELL ME WHICH PARAMETERS I HAVE TO MOVE TO AQUIRE AND DEPLOY DATA IN REAL TIME

Hi barron,
If you want to see the data update quicker, you can decrease the value in the "Samples to Read" field of your DAQ Assistant. This number controls when data is transferred from the DAQ buffer to the PC. If the sampling frequency remains the same, but this field decreases, it means the buffered data will be returned more quickly.
Hope this helps.
Thanks,
Lesley Y.

Data guard real time apply vs archived log apply on physical standby

Dear DBA's,
last week i configuared DR , now the phyiscal stanby database is archive apply mode,
i want to confirm is it better to apply the archived log or should i cahnge it to real time apply .
give me sugesstions.
Thanks and Regards
Raja...

One question are you using ARCH transport to move the redo? or have you configured standby redo logs and logwr transport (either async or syncronous), if you are using the archiver to transport the logs then you can not use real time apply.
If you are using log writer to transpor the redo the realtime apply reduces the recovery time required if you need to failover as trher should be less redo to apply to bring the standby up to date, which mode you use to transport redo will depend on what is acceptable in terms of data loss and the impact on performance.

Obtaining data in real-time from Microstrain wireless orientation sensor 3DM-GX2

Hello, all.
I am using
a wireless inertial sensor 3DM-GX2 with a USB Base Station from
Microstrain, and I want to read and use data values from it in LabView in real time.
But the problem is that I am not able to use the LabView examples or
the SDK provided by Microstrain either.
Link for SDK is here:
http://www.microstrain.com/updates/orientation-sdk.zip
I
have used the VI called "Read Accel and Ang Rate Serial.vi". I chose
the correct COM port for my sensor, that is COM3. When I run, I get an error in the node "VISA Read" (code -1073807339). Attached you can see a snapshot of this VI.
However,
I don't know if I have to use this VI because my sensor is a wireless
sensor (USB Base Station linked to 3DM-GX2 inertial sensor) and this
seems to be a program for reading from a serial sensor.
You can see in the link: http://forums.ni.com/ni/board/message?board.id=250&thread.id=42319&view=by_date_ascending&page=3; that there is another topic related to this, in which the discussion ended up with the users being able to read from the sensor, but I can't understand what they discussed there about communication protocols. I think I would need basic information so I could fix
my problem.
I am using LabView 8.6.
I hope you can help me. Thanks in advance.
Regards,
Francisco

Hi there, I had the same problems with this wireless sensor and the labview Vi's from the microstrain homepage. Please use the newest ones which are available from the microstrain homepage.http://www.microstrain.com/updates/labview-examples.zip The problem is in the "Read Accel and Ang Rate Wireless.vi". The node adress is missing. The node address are the last two digits of the
serial number (SN: 4200-1076 - node address=76) and is preset at the factory.
Here is a picture of the changed program.
I hope that may help you.

Hi, I would like to ask about how to capture data from real time loop.

Hi,
Here is some overvier of my project:
I have done real time control using labview 9.0. I used PID controller.
In order to optimise this controller, I need to capture data from my sensor(input) and actuator (output).
1. For example while real time control is running. I need to capture 1000 sample data (sensor(input) and actuator (output)).
Then I will used these data for PID optimisation on the other loop without intefere my real time loop.
2. When PID optimisation is completed, I will sent its PID parameter to real time control loop.
3. These operation is done in parallel.
Anybody can help me to solve these. Your idea may solve my problem.
TQ

Typically you will have to use RT FIFO or Queue communication to avoid any impact to your time critical loop.

Could anybody explain me what is data guard real time sync ??

This was asked as an interview question to me . am a fresher please help me out..
thanks in advance.

Hi,
I suppose you mean Real Time Apply ? That's very popular mode used when the shipping method of standby databases is synchronous (as you probably know Dataguard support two redolog shipping modes - asynchronous and synchronous). In your case of asynchronous redolog shipping there is one step further - use of Real Time Apply instead of shipping archived logs. So instead of waiting for redologs to become archived (either by database log switch or setting ARCHIVE_LAG_TARGET) and then shipped you could set Real Time Apply where blocks from the log buffer of the primary database are send directly to the standby logs of the standby database. The benefits are obvious - the lag is almost few seconds i.e. changes got applied on the standby few seconds after the primary, you don't have to worry whether the archivelogs are sent or not.
Here is link for more information about Real Time Apply at Oracle documentation Apply Services

Is it possible to acquire audio data in Real-Time using a standard sound card?

For the control of a Laser manufactoring process it is necessary to acquire and analize the typical sound. I realized this with a normal Soundblaster Card using the "SI CONFIG/READ.VI". The only disadvantage is that short parts of the signal are always missing because of the finite buffer size. Is it possible to optimize this without buying a DAQ card?

Labview RT works with three different types of targets:
-RT series DAQ (Traditional Data Acquisition board with a processor board attached to it. Connects on a PCI slot of your machine)
-Field Pointistributed modules for Data Acquisition
-PXI factor: Systems where you need a chassis and a controller then you can start filling the slots with the type of hardware that you need for your application.
Then using a traditional SoundBlaster Card to acquire data under Labview RT is not going to be possible at the moment.

How can I get updated data in sub VI in real time?

Hello.
I'm making application using Labview 7.0.
What I want to do is the data acquisition changing some parameters. I get the data each time
I changed variable parameters. I can do it in sub VI by inserting array component into 'for' loop.
As loop iterates, the parameter sets are changed, and new data is inserted into array by 'replace subset array'.
New data fills the array by each iteration.
However, I can't bring this result array to my main.vi. Sub VI gives me the result array only when
its processes are done. I want to display the data while parameters changing is still on
the way.
Are there any solution to get the output of sub VI while the it is not finished yet?

Hi Joewun:
Yes, you can update that data in real time.
It's done using references and property nodes.
You can Create Reference of an array in your main VI
In your SubVI, create a new Input to an array reference, and insert a Property Node function into the For where you update the value, and select Value property.
This way when your array updates in the SubVI you will see the changes in your main VI.

How to save data in a 4D array and make partial plots in real time?

Hi, this is a little complex, so bear with me...
I have a test system that tests a number of parts at the same time. The
experiment I do consists of measuring a number of properties of the
parts at various temperatures and voltages. I want to save all the
measured data in a 4-dimensional array. The indices represent,
respectively, temperature, voltage, part, property.
The way the experiment is done, I first do a loop in temperature, then
in voltage, then switch the part. At this point, I measure all the
properties for that condition and part and want to add them as a 1D
array to the 4D array.
At the same time, I want to make a multiple plot (on an XY graph) of
one selected property and part (using two pull-down selectors near the
XY graph) vs. voltage. (The reason I need to use an XY graph and not a
waveform graph, which would be easier, is that I do not have
equidistant steps in voltage, although all the voltage values I step
through are the same for all cases). The multiple plots are the data
sets at different temperatures. I would like to draw connection lines
between the points as a guide to the eye.
I also want the plot to be updated in the innermost for loop in real
time as the data are measured. I have a VI working using nested loops
as described above and passing the 4D array through shift registers,
starting with an array of the right dimensions initialized by zeroes. I
know in advance how many times all the loops have to be executed, and I
use the ReplaceArraySubset function to add the measured properties each
time. I then use IndexArray with the part and property index terminals
wired to extract the 2D array containing the data I want to plot. After
some transformation to combine these data with an array of the voltage
values in the form required to pass to the XYGraph control, I get my
plot.
The problem is: During program execution, when only partial data is
available, all the zero elements in the array do not allow the graph to
autoscale properly, and the lines between the points make little sense
when they jump to zero.
Here is how I think the problem could be solved:
1. Start with an empty array and have the array grow gradually as the
elements are measured. I tried to implement this using Insert Into
Array. Unfortunately, this VI is not as flexible as the Replace Array
Subset, and does not allow me to add a 1D array to a 4D array. One
other option would be to use the Build Array, but I could not figure
out if this is usable in this case.
2. The second option would be to extract only the already measured data
points from the 4D array and pass them to the graph
3. Keep track of the min. and max. values (only when they are different
from zero) and manually reset the graph Y axis scale each time.
Option 3 is doable, but more work for me.....
Option 2: I first tried to use Array Subset, but this always returns an
array of the same dimensionality of the input array. It seems to be
very difficult, but maybe not impossible, to make this work by using
Index Array first followed by Array Subset. Option 3 seems easier.
Ideally, I would like option 1, but I cannot figure out how to achieve
this.
Your help is appreciated, thanks in advance!

I love autoscaling, that's the way it should be.
