Read Differentiation Value in Real Time

HI!
I have a analog input, and I am going to read the differentiation
value of analog input in REAL time! I did try the differentiation.vi
in Labview before, unfortunately it didn't work properly! Can anybody
help me to solve this problem please! Thank you!

Hi,
If I understand correctlly, you want to differenciate [dx(t)/dt] the input
signal. To make this discreet, you must calculate the difference between
current sample and the previous sample, devided by the time difference (
DX/DT ).
so :
Value X1 on T1 (previous sample)
Value X2 on T2 (current sample)
difference = (X1-X2)/(T1-T2)
or in general: difference = (Xn - X'n-1') / (Tn - T'n-1')

Wiebe.

How to measure and plot RMS value of real time data?

hi
i need to measure and plot real time RMS value of EMG voltage. I made a VI. But I dont know why it didn't work. Can anyone please help me out? My VI is attached in 2013 and 2011 both version. One sample data is also attached. Thanks at advance.

You seem to select EMG voltage vs Angle(Z-axis). Is that really what you want? More resasonable would seem e.g. EMG voltage vs. time.
If you want to process the 3D (xyz data), you probably need to add some more math). Why are you taking the absolute value? RMS does not care about the sign anyway, right?
They you are trying an XY graph with a single point, because your Y value is only a single number. You need an equal number of points for Y.
Here's a quick modification that graph EMG(mV) vs. time(ms) and takes the RMS of the EMG data. See if this gives you some ideas.
Please provide more information what you want to do with the angles.

Metric shows real time value but does not show historical data

I am using OEM 12c.I am facing an issue and I don't know where to look for problem.
I had created one customized metric for percentage flash recovery area through metric extension.I deployed to it target databases.
When I check it through Database --> All Metrics it shows me real time value for metric,Collection schedule,upload interval and last upload time.IT is all fine.
When I check metric value history,
For all the columns like Last Known Value,
Collection Time stamp,
Average Value,
High Value,
Low Value
it shows no data.It even does not show anything in Metric Value History graph.
Even the metric test in Metric Extension works fine.
All the client agents are uploading the the data to OEM successfully.
Any help,guide is appreciated.

bit late but there are two options on metric creation "Alerting Only" or "Alerting and Historical Trending" - I assume you need the latter to show history so was this option used?

Pin myself but found Google Map is not real time map (few years before)

I recently pin a place on my event, but I found google map is not a real time map (not a few days different but few years different) It is an old map. I discovered this from the satalile map.
Any one can help on this?
Thanks

I think this is a problem that affects some areas of the world, especially Asia where governments are a little more sensitive. It is the same here where from my window I can see a new bridge completed some 3 years ago that is not shown at all.

How to determine time value of a .wav file in real time as it plays?

Hi all.
I need to build a vi in which a .wav sound file is represented in a Waveform graph, and at the same time, I want to play that file, and have a vertical cursor line running along the Waveform graph, in order to have a visual representation of where the sound track is, in terms of time.
Making the .wav file to appear graphicaly on a Waveform graph was an easy task to do, but then, I was´nt able to extract the time information of that .wav file, at the same time that this file is being played.
This is a very common situation in music players, video players etc, where some kind of graphical artifact, represents in real time where the track is while it plays.

Hi, this is the first ActiveX control I have played with but its really cool.
I read this first: -
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay10/mmp_sdk/iwmpcontrolsinterface.asp
Which covers "The IWMPControls interface provides a way to manipulate the playback of a media item."
Then built the attached sample.
It should now be straight forward to attach the position information shown to a graph control cursor postion.
You will need to set a file of your own choosing in the VI first.
Let us all know if this is what you wanted.

TDMS database and treat its values as real time data.

Hi,
I'm newbie in using labview. Actually I wanna import data from TDMS database and treat it as real time data. Although I have done the first part which is importing the data inside the program by reading TDMS and selecting channels and groups, I couldn't find way for second part which is treating data as real time one. I tried Build Waveform, but it didnt work. Would you please help me to solve this problem ? I appreciate your helps.

reza_amin,
I don't understand your word "build waveform". If you write waveform data to a tdms file, you will read waveform data directly from the tdms file.
If you are using LabVIEW 2012 (download from http://www.ni.com/trylabview), you could find a tdms example VI in "C:\Program Files\National Instruments\LabVIEW 2012\examples\file\plat-tdms.llb\TDMS - Concurrent File Access.vi". This example VI demonstrates how to write Sine Waveform into a tdms file and read the Sine Waveform from the tdms file.
Hope this helps and enjoy your LabVIEW journey. :-)

Real time ROLAP or Automatic molap cubecube does not update the value

Hello Everyone,
I am working with Real time Rolap and Automatic MOLAP cube. I had created cube using AdventureWorks DW sample given by Microsoft Tutorial. when i fire insert query, It updates data. It works fine in both the cases after reconnecting in SSMS and SSAS browser.
But I have a one database table in SQL server with 4 varchar and 10 numeric fields [simple table with one primary key without any relationship with other table]. I tried to create both type of cube from direct database table [selecting varchar fields as
dimensions and numeric as measures], created partitions, specified server side tracking table. It processes the cube. but when i add rows into this table. It inserts record but does not update in SSAS browser or SSMS browser.
Please help me what is the problem???
Thanks in Advance!

I noticed the same behavior reported by Bob: Not regarding the "process filter" or the "update frequency" selected "CPU Time" column is only updated when details dialog is open. I noticed it just today (which triggered the search here), I wonder if this "feature" has been always present or maybe activity monitor is getting lazy?

XML file issue real time

Hi guys,
My question is in a real time scenario how the file is asked for ?
As for testing a simple file scenario we usually get the sample file in XI from Message mapping tool only, this sample file contains primary tag of message type with attribute of namespace : <b><ns0:MT_FILE_INPUT xmlns:ns0="http://bsptrng.file2file"> </b> "
<ns0:MT_FILE_INPUT xmlns:ns0="http://bsptrng.file2file">
   <Record>
      <Row>
         <FirstName>q</FirstName>
         <LastName>R</LastName>
         <MiddleName>S</MiddleName>
         <City>Dehradun</City>
       </Row>
   </Record>
</ns0:MT_FILE_INPUT>
but when a client will provide us a file it will be a simple xml file like...
<Record>
      <Row>
         <FirstName>q</FirstName>
         <LastName>R</LastName>
         <MiddleName>S</MiddleName>
         <City>Dehradun</City>
       </Row>
   </Record>
As you can see primary tag of Message type with namespace will be missing...
because of that mapping exception is thrown in pipeline service....
<b>My question is how to tackle this ...</b>

Scheduling in Real-Time Java

Hello,
I have some questions concerning how scheduling in fact is intended to be performed in a RTSJ based Real-Time Java System.
As far as I understood, RTSJ requires pre-emptive priority-based dispatching of Schedulable objects.
This means that the execution eligibility of a schedulable entity is mainly its priority.
That causality is reflected within the specification with the (one-and-only specified) PriorityScheduler, which is the base scheduler for actual Real-Time Java applications.
Furthermore, there is a notion of extensibility of that PriorityScheduler described by RTSJ,
in order to provide further scheduling mechanims and feasibility analysis algorithms (please correct me if there are any wrong assumptions).
This is the point, where everything becomes really weird to me ...
As far as I could investigate, in most RTSJ implementations based on a POSIX compliant system underneath (like Java RTS does on RTLinux or Solaris)
each (Realtime)JavaThread is mapped 1-to-1 to a light-weight process on the operating system level (e.g. a pthread).
So far, we have no "green threads" within the JVM, but real LWPs scheduled by the OS.
The difference between "normal" and "real-time" threads lies in the scheduling policy used for that mapping.
While normal Java threads probably map to SCHED_RR or SCHED_OTHER, real-time threads are scheduled by the OS via the SCHED_FIFO policy in order to achieve a better real-time predictability.
However, the OS's scheduling mechanisms automatically make decisions about the right positioning of a LWP within an appropriate run-queue, due to thread's preemption, blocking or release (even dynamic priority changes) activities and its scheduling policy.
That's exactly why I ask myself, what is the need of a Scheduler representation within a JVM?
Furthermore, how a Scheduler extension is able to incorporate with the threading model and the underlying scheduling mechanisms of the OS?
One point could be a situation where a real-time JVM runs directly on top of the bare hardware and has to perform scheduling decisions on its own.
The Scheduler API could then be understood as an extension mechanism of a kind of JVM-intern scheduler (e.g. the PriorityScheduler), thereby allowing scheduling decisions to be made even in user defined Scheduler implementations.
A similar use case for an OS-based scenario could be if a JVM is intended to pass scheduling/threading routines of the underlying OS (eg. a part of the POSIX API)
up to the Java application level in order to provide the opportunity for a kind of application defined scheduling (like e.g. in the MaRTE OS).
Unfortunatelly, after introspecting the RTSJ API, both conclusions seem to me to be wrong.
So far, Java RTS seems not to provide any mechanism for reaction on scheduling events/decisions, neither intra-JVM nor from an underlying OS outside of the JVM.
Furthermore, there is no notion for incorporation with the base PriorityScheduler for making extended scheduling decisions.
I hope this post could bring me more light into the scheduling idea behind Real-Time Java systems as intnded by the RTSJ.
Sincerely,
Vladimir

Vladimir.Nikolov wrote:
That means, that a scheduling policy different to PriorityScheduler can only be assigned to a Schedulable object if it is supported by the OS and the JVM?Well it has to be supported by that implementation of the RTSJ. Howe that is done - ie whether it requires OS support - depends on that VM, the OS and the actual scheduling policy.
It also seems that at the current state of the art the PriorityScheduler representative within the JVM is intended only for manipulating a feasibility set of Schedulable objects (supporting online feasibility analysis)?
However, since user-defined scheduling is not intended by the specification, applications have to rely on the feasibility analysis based on the underlying/supported scheduling mechanisms.
Thus, in the current Java RTS implementation this would be the "default" feasibility mechanism based on the PriorityScheduler.
Unfortunatelly I can not figure out the need of maintaining a feasibility set, since feasibility, as specified for the PriorityScheduler, is a simple asumption that we have "an adequatly fast machine to handle the periodic and sporadic load"?
I actually assumed that feasibility analysis performs real cost budgeting taking into account deadlines and so on, but it seems to be specified simply to make a negative statement always when aperiodic tasks are involved ?The RTSJ scheduling framework provides support for feasibility analysis by defining the admission control methods eg setXXXIfFeasible. However the RTSJ does not, and can not, mandate any non-trivial feasibility algorithm because in simple terms no such general algorithms exist. There are some static feasibility tests in the literature and you could apply those offline to your application (assuming you can find the values of all the "magic" numbers in such formulae - which is generally not the case). At present the RTSJ doesn't support even these simple feasibility tests because blocking-time is not recorded in the release parameters - something being addressed in RTSJ 1.1. In any case unless there is a pluggable framework for feasibility tests it would be a waste of time for VMs to implement them given they can (more) easily be done offline using other tools.
Only dynamic admission control is really of interest and as far as I am aware no such general dynamic admission control policies exist (anything you find in the literature is very context specific). So it is left up to an implementation as to whether they try and define dynamic admission control algorithms - and so far none have because they don't have one.
In "Getting More Flexible Scheduling in the RTSJ" Wellings and Zerzelidis propose some (more or less) "minor" extensions to the RTSJ API in order to enable hierarchical scheduling within the fixed priority framework.
Since Andy Wellings is a member of the RTSJ Technical Interpretation Committee, is there any attempt to evolve the specification in a similar direction as described above, in order to support more flexible scheduling mechanisms and feasibility analysis?If there is ever a RTSJ 2.0 then more sophisticated scheduling support is one of the items on the wishlist. But there's no guarantee there ever will be a RTSJ 2.0

Fico interview questions and Real time tickets with resoving details

hi sap gurus
i have done sap-fico iam in job trails. can any body help me Fico interview questions and Real time tickets with resoving details
regards
prasad.v
Edited by: chinna prasad on Jun 5, 2008 4:10 PM

Hello Prasad,
Before attending interviews.....First you need to understand general things like CV writing, projects, sub modules etc., you should be gain knowledge on these concepts then you can move further.
1. CV 2.Projects 3.your strenths in sap (reading..reading...reading....practice...practice...practice)
2.you please interact with your friends who is on trails, then you can get more information like interview process, methodology, technical etc.,
I am sending some real time interview tech questions which will useful for you.
Questions:
1.When tickets are raised by end users who will give priority? After resolve the tickets who will close the status?
2.In real time at a time how many normal periods, special periods, MM periods we can open?
3.What is client dependant & Independent?
4.How to transport configuration settings from one client to another client or production client, which tools we can use for transport?
5.Why we donu2019t assign business area to company code?
6.What is the difference between General GL A/c, Control A/c, Reconciliation A/c & Offsetting A/c?
Answers:
1.The priority is generally decided by the Coordinator on the client side. After tickets are resolved, they will have to be closed by the coordinator on the customer site
2. In FI as many as you wants. In MM only 2 (current month + previous
3.Certain tables and customizations made in one client will affect the other clients also - then it is cross client i.e, client dependent. While if the changes made in one client has no impact on the other client - it is said to be client independent
4.Transports from one server to the other can be made with the help of transport requests. When a configuration is done the system generates a request number. First release the task and then release the request. Use TC-SE10 / SE09, SE09: workbench transport; SE10: customizing transport. But currently no such difference actually exists.
5.because in case of multiple company codes, same business area can be used across company codes. Business area is cross company code, means it is not confined to one company code thatu2019s why we don't assign BA to any of the company codes. It is client dependant, not company code dependant. We can pass values from one company code to any of the BA in that client.
6.General GL Account are those used for standard posting like for example Income and Expenses Accounts
- Control Account are basically used for reconciliation between modules like FI and CO, to ensure that both the modules are in sync.
- Reconciliation Account are those specific covering ADK (A-Assets, D-Customer, K-Vendor). For example a Customer Master would be mapped to a Bills Receivable Reconciliation Account and any transaction that needs to be posted are done against the customer code.
- Offsetting Account are used for variety of reasons and few examples are Intercompany Postings, at the time of Implementation when TB and Balance sheet are uploaded would be offsetted against a dummy account.
All the best.....dont forget and pl assign points if useful and if u have any querries pl revert back
thanks

Need of value mapping and fixed values in (conversions)under graphical map

hi.
helo all.
i just want to know what is the need of value mapping and fixed values in (conversions)under graphical mappping.
can any body explain me with real time example .
waiting for your response.
bye.

Hi Seetha Ram,
Value mapping: Where we maintain a table of values which are mapped.
based on the incoming value we can send the respective resultant value.
for Eg: for language SAP maintains as EN --> English etc

Value mapping performance using LookUp API

All,
We are using Value mapping look up from an external table using JDBC adapter and Lookup API. The scenario works good, but the performance is a hit for us as it is taking 7 seconds for the first step and the subsequent steps are taking much longer. In the performance header it shows that the steps "DB ENTRY QUEUING" and "DB SPLITTER QUEUING" are taking 90% of the time even though mapping execution is real quick.
We tried the below things which did not help us analyze or isolate the problem.
1. We increased the number of dialog processes from 3 to 8. (Optimal value should be 5)
2. We tested the scenario using Value mapping in ID instead of external table. But it is almost taking the same time in the above two steps mentioned.
I would like to know whether any kind of configuration settings to be done on the server like "specifying connection pool capabilities" etc...
Any pointers would be really appreciated.
Thanks and Regards,
GP

Hi,
Have you seen this weblogs by Prasad recently:
/people/prasad.illapani/blog/2007/03/08/performance-tuning-checks-in-sap-exchange-infrastructure
/people/prasad.illapani/blog/2007/04/20/performance-tuning-checks-in-sap-exchange-infrastructurexi-part-ii
Also are you doing multiple lookups or a single lookup? If you are using multiple lookup for multiple fields which has the same logic then try to use global variables.
