How fast DSC loggs data

Hi,
I have an application that detects frequency and THD% and then Log this data to data base.
I'm thinking of using DSC for this application and I wonder how fast can it be.
will I lose data when using DSC for this application.

The DSC engine can't save data with microsecond timing resolution for an analog signal. But you can take your signal and flatten it to a binary string. Then write the resultant string value to a string tag configured as a BLOB. Here is a 7.0 example for creating the binary string from array data. You can flatten clusters of data and then use the historical DSC vi's to get the logged data.

How can I get max, min & average (hours with minutes) of fast 30 days data ?

Hi,
you have to use analytical functions:
SELECT start_day,
       round(AVG(daily_avg)
             over(ORDER BY start_day ASC RANGE BETWEEN INTERVAL '30' DAY preceding AND INTERVAL '0' DAY following)) AS moving_avg,
       round(MAX(daily_max)
             over(ORDER BY start_day ASC RANGE BETWEEN INTERVAL '30' DAY preceding AND INTERVAL '0' DAY following)) AS moving_max,
       round(MIN(daily_min)
             over(ORDER BY start_day ASC RANGE BETWEEN INTERVAL '30' DAY preceding AND INTERVAL '0' DAY following)) AS moving_min
FROM (SELECT trunc(t.start_time) start_day,
               AVG((t.end_time - t.start_time) * 24 * 60 * 60) AS daily_avg,
               MAX((t.end_time - t.start_time) * 24 * 60 * 60) AS daily_max,
               MIN((t.end_time - t.start_time) * 24 * 60 * 60) AS daily_min

How fast will I use my hotspot data?

Hey all,
I just activated the mobile hotspot service because my internet is down, a tech can't visit me until this Saturday, and I absolutely need internet for school. I only paid for the 2 GB usage, but I also have a roommate. How fast will we burn through our usage total if we're using it strictly for internet things like our school research, facebook, and message boards like this one? I realize it could be very subjective. All I'm looking for are reasonable estimations.
Thanks.

Well it depends of you have 3G or 4G, and if you stream lots of audio and video or not. If you lay off these things, you should manage to stay within a 2 Gig limit without too much trouble. Static web browsing, email, IM, googling for research, chat, these things are all fine. YouTube, Hulu, Pandora, Slacker, etc suck it down pretty quick. Hulu and YouTube at standard definition can use 200 meg per hour. HD movies can use 1.25 Gig for 2 hour movie. Streaming radio at 74 kbs use about 30 meg per hour. When I had the USB Tethering on an old 3G phone, I didn't use anywhere near 2 Gig in a month.

How to store the data coming from network analyser into a text or excel file

Hii everyone
I'm using Agilent 8719ET network analyser and wish to store the data coming from netowrk analyser into a text file/ excel file.
Presently I'm able to get the data on Labview graph using GPIB . Can anyone suggest how to go ahead after collect data sub vi. How can the data be stored into a file apart from showing on the graph?
Attached is the vi for kind consideration...
Looking for help

First let me say that your code really looks pretty good. The data handling could be made more efficient by calculating the number of datapoints that are going to be in the completed dataset and preallocating the entire array -- but depending upon your answer to my questions, the logic in the lower shift register may be going away - so we won't worry about that right now.
The thing I need to know before addressing the data storage question is: Each time you call "Collect and Display Data.vi", how many element are in the array? Are you reading single data points, or a group of data? (BTW: if the answer to that question is obvious based on the way the other VIs are setup, I don't have the drivers so I can't tell what the setup values are.) Second, how fast does the loop iterate? Are we talking msec per loop?, seconds? fortnights?
The issues here are two-fold: how much data? and how fast is it coming? The answer to these will tell you how to save the data.

How can i store data in term of a tree structure

how can i store data in term of a tree structure

What a tree is the question. If you just want a fast access, ehats about Hashtable or dictionary classes ? The data there is structured in a tree. For a simple binary tree, you can use something like
class Node {
Node(Object data){
   Node left;
   Node right;
   Object data = data;
void insert(Object data, Node parent){
int test = data.compareTo(parent.data);
if(test < 0 ){
    if(parent.left == null){
      parent.left = new Node(data);
    else{
      insert(data, parent.left);
else{
    if(parent.right == null){
      parent.right = new Node(data);
    else{
      insert(data,parent.right);
}And so build up a binary tree. The traversing methods can be found in almost any good book (pre-order, post-order, in-order), for search you have just to look at greater/smaller and descend in the tree.
The Object data can be changed to what you want for storage, String, or primitive Numbers, Vectors ...
Is that what you search for?

How do I read data from a DMM or DC Power Supply at a specified rate?

I have a PXI system with 4071 DMMs and 4110 DC Power Supplies. I want to be able to measure the power consumption of my DUT as it performs various operations. This is what my process flow looks like:
1. Configure DMM and Power Supply
2. Wait for DUT to go into a certain mode
3. Start Acquiring data from DMM and PS.
4. Wait for DUT to get out of this mode
5. Stop Acquiring data from DMM and PS.
Since the duration of step #4 is uncertain, I cannot tell the units to collect a predetermined number of samples and give it back to me. Instead I have to take readings as long as it's required.
I'm attaching screenshots of my setup and read process. The reading is done inside a timed loop which is running at 1kHz.
The problem is that using niDMM Read Multi-Point or niDCPower Measure Multiple takes 5-9ms before I get a reading, so I'm not really getting 1ms resolution in my data. I'm sure there are other folks who have had the need to read data from these devices with better time-resolution, so if anyone can point me in the correct direction, it would be great. I'm pretty sure I'm not doing the correct thing here.

What is really confusing to me is why you are even using the multi-point function when you set the sample count to 1. If you want multiple points, request multiple samples and let the DMM acquire them at a rate you specify. If you want a single sample, use the normal Read. You also need to pay attention to how fast the DMM can acquire. If you want the fastest sample rates, you might be a lot better off with a DAQ board.

How to implement screen exit for a SAP standard transaction
Introduction
SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
To pave way for this, SAP has provided the option for screen exits. Usually, SAP provides the following:
An append structure in the database table with the new fields.
A subscreen area into the standard screen where the programmer can attach his subscreen of his own program with the new fields.
A function group under which the new subscreen has to be created with the new fields.
Function exits to synchronize the PBO and PAI of the standard SAP program with the PBO and PAI of the subscreen so that data can flow back and forth between the standard SAP program and the program written by the developer for the subscreen. These function modules also exist in the same function group under which the subscreen will have to be developed.
Finally, a linkage has to be done between the subscreen area of standard SAP screen with the custom subscreen constructed by the developer.
Typically, SAP provides an enhancement in which the developer can create an append structure, use the function exits to synchronize the PBO and PAI of the standard SAP program and the custom subscreen program, and make the necessary linking( as mentioned above in step 4. But, again, this is not a hard and fast rule. Linking in some case, is also done by configurations.) SAP also usually provides the name of the function group under which the subscreen has to be developed.
Necessary guidance about implementing a screen exit development is usually available in the Documentation section of the enhancement ( can be availed by transaction SMOD).
Pre-Requisites
The developer to work on screen exit should have essential knowledge on the following:
DDIC concepts, including the knowledge of append structure.
Concept of SAP Enhancements and implementing them using Projects.
Concept of function exits.
Knowledge on Module Pool including subscreens, Tabstrip controls etc.
Steps
Guidelines
So, a developer can follow the guidelines mentioned below to implement a screen exit to a standard SAP transaction, as and when required:
Find out the Required Enhancements
Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton SAP Applications. A list will appear that contains information on all the enhancements, categorized under functional areas. Developer must search for the enhancements relevant to his functional area of interest for e.g., Purchasing, Asset Accounting, etc.
Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
Utilize the Enhancement in a Project
After you have found one, do as directed in the documentation. Generally, the steps are as follows:
Create a project using CMOD including your enhancement.
Create the append structure with new fields.
Go to the desired function group and create a subscreen with the new fields. Write PBO and PAI for the subscreen, if required.
Use the function exits in the enhancement to link the PBO and PAI of the subscreen with that of the main SAP program supporting the SAP transaction.
Maintain necessary linkage between the subscreen area of standard SAP program with the custom subscreen developed along with the custom program name. This can be done in the project (developed by CMOD including the enhancement) or outside as a part of configuration.
Activate the project.
Test to ensure that required functionality are met.
Case Study 1
Add three new custom fields for Asset master and maintain information for them
Requirement
Three fields in the legacy system have to be maintained in Asset master. These fields are:
Original Asset number 20 characters
Location 2 15 Characters.
Model no 20 characters
Location 2 should start with L.
Pre-Analysis
Finding out the Enhancement
As described above, the enhancement is determined. It was found, that enhancement AIST0002 will serve the purpose. It contains the following components (can be viewed by transaction SMOD):
Exit Type Description EXIT_SAPL1022_001 Function Exit Check of User-Defined Fields when Using Create and Change BAPI EXIT_SAPLAIST_002 Function Exit Transfer Data for User Subscreens in PBO. EXIT_SAPLAIST_003 Function Exit Transfer of User-Defined Fields to SAP Master Data Transactions CI_ANLU Customizing Include Include structure to add new fields
Studying the Function Exits
The function module level documentation for the function exits are then viewed from transaction SE37. The documentation clearly laid out for the purpose for their use:
EXIT_SAPLAIST_002
Function module Level Documentation
This function module is called by asset master data maintenance at the start of the dialog. (When changing, it is called after reading of the data from the database; when creating it is called after the transfer of the default values from the asset class and reference asset.) The purpose of the function module is to enable this function group to recognize the master data. For interpreting or controlling master data fields that are important for user fields, it is possible to transfer to global variables at this point, so that they can be recognized when the user subscreens are processed.
Import Parameters
Understanding
This function module is called at the PBO to pass the information retrieved from the database to pass them to the custom subscreen and its underlying program. Import parameter : I_ANLU will be populated with the values for user-defined fields which will be passed to the subscreen program. So, there must be some sort of variable assignment from I_ANLU.
EXIT_SAPLAIST_003
Function module Documentation: This function module is called by SAP asset master data maintenance after the screens are processed, but before saving. The purpose of the function module is to transfer fields entered on user sub-screens of SAP asset data maintenance to the database for updating. The export parameter for this function module is:
Understanding
This function module will be used to transfer the user entered data in the subscreen fields to the main SAP program, which will then be saved into the database.
Studying the Documentation of the Enhancement
The enhancement documentation (as is viewed from the initial screen of SMOD] also supports the idea. Moreover, it informs that we need to develop a subscreen under function group XAIS. This is the function group under which the two function exit modules also exist. So, if the custom subscreen refers to the global data of the function group XAIS, then those values will also be available to these function exits as well.
Going to SE80 and viewing the function group XAIS helps us to inform that there are three DDIC tables declared for it:
Deciding the Final course of Action
After making all the investigations, the final course of action was determined.
SrlNo Step Justification
A project has to be created using transaction CMOD where the enhancement AIST0002 will be included.
Customizing include CI_ANLU has to be created with the custom fields demanded When CI_ANLU will be developed, the custom fields will get appended to the database table ANLU. Also, these fields will be used to create screen fields in the new subscreen.
A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be CUST (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
In the PAI of the subscreen, validation for Location to start with L will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
In the custom include of the function exit module EXIT_SAPLAIST_002, the following code will be written:-
ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
In the custom include of the function exit module EXIT_SAPLAIST_003, the following code will be written:-
E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done otherwise, the new custom subscreen will not be displayed in the Asset master screens.
Development
Creating a Project to include the enhancement
Go to transaction CMOD and create a project.
Enter a description for the project. Then, click on the pushbutton Enhancement Assignments in the Application Toolbar.
Enter the name of the enhancement and Save.
Go to Components.
Creating Custom Include for ANLU
The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
Create the include structure with three new fields, as required. Then, save and activate it.
Develop the subscreen and the program
Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
Create it as subscreen.
Then, go to the Layout of the screen and create three new fields from Database table ANLU.
Drag the fields in the screen body and place them.
Then, save and activate the screen and come back to screen flow editor.
Create the PAI module to add validation for field Location 2, as required .
Activate the whole function group and come out.
Write code in the Function Exits to synchronize the programs
Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
Then, activate everything the whole project and come out.
Complete the configuration to link the subscreen
The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
Here, the requirement is to create these three custom fields in the tab page General of asset master screen ( AS01/AS02/AS03/AS91).
Determine the Layout
To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class 1000 and click on folder General Assignment of Layout.
Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout SAP cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
Create new tab layout
Go to transaction AOLA. Copy the tab layout SAP to create another layout, say, YSUB.
System will copy all the settings and will inform you about that.
Select your newly created layout and double-click on the folder Tab page titles.
You want to put your custom fields in the tab page General. So, select this tab page entry and double-click on the folder "Position of Groups".
Here, all the field groups currently residing in the tab-page General are shown. Add an entry for your newly created fields.
Select the group box from the list. An entry will come with U padded with the custom subscreen prepared by you.
Then, save and come out.
Assign the new Layout to Asset Class
Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
Save and come out.
Test the Exit
Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to themsave. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.

I'm interested in seeing who gets the D7100 support first? Apple or Adobe!! I will go with the one that gets it out first.
FWIW,
Adobe keeps a quarterly release schedule for RAW updates. The current Lightroom 4.4 RC expires on 5/31/2013 which typically is an indication that the official release will be close to that date. According to the current list of new supported cameras, the Nikon D7100 is not slated to be supported (but that could change on release).
http://labs.adobe.com/technologies/lightroom4-4/?tabID=details#tabTop
The most likely time frame for Adobe support of the D7100 will be sometime in August or September 2013 (although there will probably be a Lightroom 4.5 RC available prior to that for testing purposes).

HOW TO VIEW SPATIAL DATA

I don4t know how to view spatial data stored in an oracle database with a graphic representation.
Are any ORACLE product to do this? Or any third party product?

In Oracle 8.1.6, OEM ships with a simple
Java viewer to help you tune your data.
At the command line, type:
oemapp sdoadvisor
In Oracle's next release (8.1.7) the JDBC
access to Oracle Spatial types is
much faster (more comperable to OCI access).
You will see the improved performance
in the OEM tool.
=====
There is also an unsupported Motif visualizer
(written in PRO*C and OCI).
You can download the motif viewer at:
http://technet.oracle.com/products/spatial/
under "sample code".
It is compiled for Solaris, but you
can compile it for any UNIX platform.
Hope this helps. Thanks.

How to load master data and hierarchies from R/3 systems

HI all,
how to load master data and hierarchies from R/3 systems.
Please explain the steps.
Thanks,
cheta.

HI,
Its normally done following: Transferring the master datasources in RSA5 to RSA6 and then replicating the DS into BW and assignment of DS to Infosource and cretaion of Infopackage and load it into the master tables.
Generally, the control parameters for data transfer from a source system are maintained in extractor
customizing. In extractor customizing, you can access the corresponding source system in the source
system tree of the SAP BW Administrator Workbench by using the context menu.
To display or change the settings for data transfer at source system level, choose Business
Information Warehouse → General Settings → Maintaining Control Parameters for Data Transfer.
Note: The values for the data transfer are not hard limitations. It depends on the DataSource if these
limits can be followed.
In the SAP BW Scheduler, you can determine the control parameters for data transfer for individual
DataSources. You can determine the size of the data packet, the number of parallel processes for
data transfer and the frequency with which the status IDocs are sent, for every possible update
method for a DataSource.
To do so, choose Scheduler → DataSource → Default Settings for Data transfer.
In this way you can, for example, update transaction data in larger data packets in the PSA. If you
want to update master data in dialog mode, smaller packets ensure faster processing.
Hope this info helps.
Thanks,Ramoji.

How to display these data

Hello,
I have a table storing data like this:
item_id status date
1 checkin 7/8/2011
1 checkout 7/9/2011
1 checkin 7/8/2012
1 checkout 7/9/2012
how can I display data like this:
item_id checkin checkout
1 7/8/2011 7/9/2011
1 7/8/2012 7/9/2012
please help me!! many thanks!!

Hi,
Welcome to the forum!
Here's one way:
WITH got_r_num       AS
     SELECT item_id, status, dt     -- DATE is not a good column name
     ,     ROW_NUMBER () OVER ( PARTITION BY item_id
                               ,                    status
                         ORDER BY        dt
                       )   AS r_num
     FROM    table_x
SELECT       item_id
,       MIN (CASE WHEN status = 'checkin' THEN dt END)     AS checkin
,       MIN (CASE WHEN status = 'checkout' THEN dt END)     AS checkout
FROM       got_r_num
GROUP BY item_id, r_num
ORDER BY item_id, r_num
;When you have 1 column on multiple rows, and you want to display it as multiple columns on 1 row, that's called a Pivot . Pivotting assumes there is something in the data that pinpoints which row and column of the output will correspond to each data item in the query. The tricky part about this problem is that there is nothing in the table that uniquely identifies the output row. In the example you gave, there are 2 output rows with the same item_id. So we need to generate something (r_num in the example above) that, taken tiogether with item_id, will uniquely identify the output row.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0). The query above works in Oracle 9.1 (and up), but if you're using Oracle 11, you might want to use the SELECT ... PIVOT feature instead of GROUP BY.
See the forum FAQ {message:id=9360002}
You'll get better answers faster if you always supply this information whenever you post a question.

How to export&import data using sql *loader

Hi all,
How to export&import data from sql*loader. Give me the clear steps..
Thanks in Advance

Hi did you already exported data from SQL SERVER? if not using SQL*LOADER you cannot export data. SQL*LOADER is only mean for importing data from flat files(usually text files) into ORACLE tables.
for importing data into oracle tables using sql*loader use below steps
1) create a sql*loader control file.
it looks like as follows
LOAD DATA
INFILE 'sample.dat'
BADFILE 'sample.bad'
DISCARDFILE 'sample.dsc'
APPEND
INTO TABLE emp
TRAILING NULLCOLS
or for sample script of control file search google.
2) at command prompt issue following
$ sqlldr test/test
enter control file=<give control file name which you create earlier>
debug any errors (if occured)
