Video & Media is the Number 1 Data Traffic Worldwide

BW Consumption wise: Video & Media is the number 1 Data Traffic worldwide. Expected to grow exponentially in the coming years. Its a fascanating world of live, batch, complex processing with huge & valuable data inside. Related to Security, Revenue Opportunities, And many other market verticles. In order to properly process it very specific knowhow in needed. We have been working in the netwroking and Media area for decades.Over last few years, working with Informatica tool the question come what is Informatica solution to Video , Audio? Media Streaming and Processing? As we could not find to date we started utilizing our knowhow to create connectors into Informatica B2B and other tools, enabling future and existing customer to use INFORMATICA instead of dedicated hardware. One example is the Media Sensor (https://community.informatica.com/solutions/main_screen_vod_media_sensor). Appreciate any feedback and thoughts. Thanks, Gal

Dear Experts, I am facing facing an issue with lookup transformer in B2B DT, seeking your advice to fix the issue: Sub: Lookup transformer is returning NULL inside Repeating group. I have created variable of SILICON_TYPE of type cde:lookuptable and set up one lookup transformer LKP_SILICON_TYPE. When I am referring to that lookup table in repeating group and trying to pass output to one of the data holder, it is returning NULL. However when I am running it solely outside repeating group for any specific key value it is working find as expected. In repeating group, I am using Map action to map return value of Lookup table to map with output data holder along with other Map actions. Please find screenshot of variable declaration and Repeating group definition. Please provide suggestion and advice to fix the issue. Regards,Ravi

How to reduce the number of data blocks used by table

Hi,
I was trying to reduce the space usage of a particular table of my apex application which stores blob content and therefore deleted many records from it.
However, the data block usage remained the same as before.
I have tried to 'analyze' the table and validate the structure,but am unable to overcome this problem.
Could someone throw some light on what needs to be to reduce the number of data blocks used by this table?
Best Regards,
Priya Jetley

Priya:
It is likely that the BLOB content defined in your table is being stored 'Out-of-Line'. This means that the LOB columns are stored in segments of their own. These then are the segments that may need shrinking.

How to increase the number of data Business Object can pull for a report?

Hi,
I would like to ask around how to increase the number of data Business Object can pull for a report. I have a report which pulls data depending on the date range (ex. From 01/01/2007 - 01/10/2007). But, when the data that is pulled exceeds 5000, the report fails. Is there anyway to increase the number of data that BO can pull?
Thanks

Bobby,
to my knowledge we can't change that. Let me explain this, we have setting in the source system for DS default Data Transfer. there we will assign the processes. if you want to assign 4 you need to change the setting in the source system. For flat files we can change in BW System. We can maintain the setting in the Infopackage level(wht we are assigned in the Source System), but we can't change the process.
in order to check the setting in source system SBIW--> General Settings --> Control Parameters for Data Transfer.
we need to change here, this will effect to all the Data Sources. Before making changes check with your basis.
All the best.

To restrict the number of data columns displayed in BW Web report

Hi,
In the corresponding Bex query i am using 'Start Time' characteristic in the row. In the BW Web template i don't want the 'Start Time' to be displayed when i execute.
I tried to restrict the number of data columns displayed in the web item table properties but that did not help
Can i get some help
Thanks,
Mala

Hi Mala,
You can try out the following: Create a view on your query and in that view remove the Start Time char from the drilldown. Use this view as a data provider in the web template.
Hope this helps...

How do we decide the number of data base servers and application servers ?

Dear Gurus,
How do we decide the number of data base servers and application servers in BW ?
How does this number help in data load balance and reporting needs ?
Any hard n fast rule in the number of servers ?
Regards
Mohan

Hi Mohan,
Check the number of application server in the T-code SM66.... and also u can check the it in Sm50 on appplication server basiss./.
From Sm37 u can see the application server Push button.. if u click on that also.. u can see the number of application servers in the system..
Get into the individual application server and check how many Dialogue and background WP's are free,,
If u see that the considerable number of WP are free(Waiting for task).. then u can shedule the loads..
If most of the WP are busy then u need to wait to trigger ur loads to maintain the load balancing..
If one Application server is too busy then u can check the other Application Servers in the systems..
And u can shedule the loads on a specific application sever level as well using the PC..
Thanks
I hope this is clear to u..

Any way to export videos and preserve the original creation date?

I recently shot video using an NEX-5N and AVCHD as the format. Since Aperture cannot playback this format, I converted the videos using Handbrake to mp4 (H.264), and then used A Better Finder to change the creation date of the converted file back to the same date as the original file.
Importing this converted file into Aperture works great, and the imported file shows the correct metadata of the original creation date, not the date of the conversion.
But when exporting this file from Aperture, it seems like Aperture does not embed the date as metadata, and thus the only date associated with the exported video is the file-system date attached to the file, which will of course be the date of the export.
I assume this problem applies to ANY video imported into Aperture, not just those that have been converted.
Does anyone have a method for exporting video and having the original creation date remain? This is obviously a problem when exporting videos one-by-one, but would be a bigger problem if I ever wanted to export my entire video library from Aperture into another program...all the video files would have the same date!
Any feedback would be greatly appreciated!

EXIF data and video files is even more of a gray area then EXIF data and stills.
I don't do much video in Aperture so I'll take your word for it that the data isn;t imbedded into the file. In that case the best I can see is to create a custom export preset and include the Image Date in the filename. Not great but you at least have the data and you might be able to have a script use the date from the filename and somehow add it back into the file.

Increment the number with date/time string. when ever the next date come's it should reset again with initial number

i want to store the number of records in a file. Every time when ever i run the program the record will be incremented well i using forloop with count value 1 as a constant .in the for loop i am using autoincrement with the feedback node . to view the number i have attached the indicatator .the number will be increment every time . i am using number to time time stamp that is connected to get date/time string. from that we can view the date string and time string . so , my issue is when ever i close the code again it is coming with intial value . i should get from that number only where ever i close the code . after the date completed again it should come from intial value . i am attaching the code so that u guys can solve my problem.

here you can see.......the file path in case structure in that i have included my requirement of increment the number
-> if the case is true then it goes in ok file path and the no of records string will pass in the file by seeing these code u will get the clarity
my requirement is the number of records should increase ........ whnever the program runs...that i made it. by the next day again it should begain with the intial value.........that is my requirement. i hope u understand .
suggest me how can i use the intial value .......

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
Proud to use LW/CVI from 3.1 on.

How can i count the number of data patches in a numeric array

Hi All

BobLondn wrote:
Can I build a 2d array where I can store on one column the index of each data patch and on the second column to store the length of elements of relevant data patch.
Here's a quick example (LabVIEW 9.0) that stores the start index and length of all negative patches in a 2D array.

How to restrict number of Data Records from Source system?

Hi,
How can I restrict the number of Data records from R3 source system that are being loaded into BI. For example I have 1000 source data records, but only wish to transfer the first 100. How can I achieve this? Is there some option in the DataSource definition or InfoPackage definition?
Pls help,
SD

Hi SD,
You can surely restrict the number of records, best and simplest way is, check which characteristics are present in selection screen of InfoPackage and check in R3, which characteristics if given a secection could fetch you the desired number of records. Use it as selection in InfoPackage.

Reducing Number of Data Points Acquired?

I am interested in knowing how to reduce the number of data points written to a file that was acquired at 5 Hz. I have tried to lower the sampling frequency below 5 Hz on a Compaq Daq, but I get an error saying that is an incorrect value. So, if I can't sample below 5 Hz, how do I acquire fewer data points, or how do I reduce the number of data points written to the file? I have tried Sample Compression which just ignores data points. So, an acquired value is written multiple times at the same rate as having no compression at all. I calculated the sampling frequency from the data file witha compression ratio of 20, 30, and 40 to still be at 5 Hz.

If you want to "compress" your data then you should perhaps try the "Decimate (single shot) VI " Owning Palette: Signal Operation VIs. With this VI you can average down an array. If you have an array sampled with 5Hz and you set the decimating factor to 5, and average=true. Then the output will be an an array downsampled to 1 Hz, with each value equal to the average value of 5 samples in the input array. The decimate function is quite new. It came in Labview 8.2
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Change number of data file

I need to copy the data files to a SAN and want to change the number of data files form 4 to 1. This is only a small database (22Gb). I don't know how to delete the data files and re create them.
Regards
Hans

Hi Hans,
no, you can also do it using DBMGUI. The process is really the same as when you're doing a homogenous system copy, the only difference is the target itself is the same db instance.
You'd have to make sure you've backup up all (data+log) and no further data was created (for example by making a full data backup in ADMIN mode and saving the log). Then you'd need to initialize the DB and specify the desired number of (data) volumes and make sure you select the radio button labelled 'Create instance for recovery' during the initialization process, so the instance will only be put into ADMIN, after which you can then recover (using the backups made in the beginning).
I'd recommend to test this out yourself on a small (non production) db instance.
In comparison, from MaxDB version 7.6.00 Build 22 onwards, you would just have deleted the unwanted volumes (taking into respect that the left over volume can hold all data).

Roland

My waveform chart is suppose to be with respect to time but I've noticed it is plotted with respect to the number of times through my VI

I was under the assumption that waveform charts in LabVIEW 6i atomaticly displayed wired data with respect to time in seconds. However, I noticed that my chart plots data with respect to the number of data points my VI has generated. Is there anyway to fix this so that the chart actually plots vs. time. I've attached VI. The CIN is to a Computerboards Inc, thermocouple. Any help would be appreciated.

tepTInScan.VI ‏73 KB

It appears that the chart is set to display relative time but since you don't have the acquisition in any kind of a loop, your relative time is pretty meaningless. You've got the dX of the chart set to be one, so yeah, at the beginning, the x scale numbers are going to be the same as the number of aquisitions until you've run it more than 60 times. At this point, you'll see the x scale show minutes and seconds. If you want absolute time for the x scale, look at the examples Real-Time Chart.vi or Variable-Time Chart XY.vi.

How do I determine the number of plots on a waveform graph?

How do I determine the number of plots that have previously been plotted on a waveform graph? I am loading dynamic data from a file. If I convert to an array and size it and there is only one plot, I get the number of data points and I don't know how to tell the difference.

Usually by reading the graph terminal or a local of it and determining the first or second dimension (not sure which at the moment) size of the resulting 2 dimensional array. If it is a 1 dimensional array you have either only one plot or an array of clusters each representing one plot. But as these data types are determined by compile time, there shouldn't be a problem with this causing ambiguity.

Number to date and date to number??

select substr(to_char((to_date('1970-01-01 03:00:00','yyyy-mm-dd hh24:mi:ss')+TIMESTAMP/86400000),'yyyy-mm-dd hh24:mi:ss'),1,19) from table where rownum<2;
Result :2006-10-03 19:25:07
but without conversion
select timestamp from table where rownum<2;
Result:1159892707453
Suppose i have value as date like 2006-10-03 19:25:07
I need to convert to number 1159892707453
Please note I have used standard webmethod conversion for number to date, But my developer who want know the conversion of date format to number format as mentioned above.
could you help on this
Thanks
Raj

For the number to date conversion you may find the following helpful. It works with daylight savings also - not sure if it is an issue for your region. You can get the timezone names from V$TIMEZONE_NAMES;
SQL> SELECT
CAST((TIMESTAMP '1970-01-01 00:00:00 GMT' + NUMTODSINTERVAL(1159892707453/1000, 'SECOND')) AT TIME ZONE 'Indian/Mayotte' AS DATE) ora_dt
