Process Overview: Batch Input. Batch input is used for bulk data transfers and not for near real-time data transfers. Another typical use is for periodic hourly, daily For the system administrator, batch input usually requires minimal attention, only a periodic check to make sure all batch input sessions have been processed successfully.
In the event of an error in a session, then the responsibility for triggering the error analysis and correction of the problem usually lies with the system administrator.
Detailed analysis of the problem will require the help of the department or specialist responsible for the data to be entered.
The process description here explains the typical workflow in batch-input operation from the point of view of the system administrator. Batch input operation occurs only if a customer explicitly sets its up. In this case, a regularly-recurring bulk data transfer is foreseen. Custom batch input procedures must be set up by hand. That is, the system administrator must schedule the data conversion program that creates the batch input session.
See also the online guide Basis Programming Interfaces. For the system administrator, processing of batch input sessions requires little attention. Usually, system administrators automate the starting of batch input sessions see Processing Sessions Automatically. Administrators can also start batch input sessions explicitly from transaction SM35, if necessary. The batch input system offers detailed logging and powerful analysis tools to help you find out the cause of a problem see Analyzing Sessions and Displaying Session Logs.
The batch input system processes all correct transactions in a session. It also guarantees that successfully completed transactions in a session cannot be run again. To correct transactions with errors, the system administrator or the responsible department can interactively correct and reprocess the transactions.
See Correcting a Session. All of these data transfer techniques are brought together in the data transfer workbench. And you can branch to transaction SM35 to run batch input sessions from the workbench.
You can find information on the technical implementation of batch input and fast input and on the programming of these techniques in the online guide Basis Programming Interfaces.Below is an example of the code I used to do this. This is for Windows NT based batch execution i. The promptString is the text that is displayed to the user.
The end result of this line is that you are asked to provide an input, and whatever input this is, it gets stored into an environment variable which can be used later in the code.
The second line of code then uses an 'IF' statement, together with a 'GOTO' statement, to test this saved environment variable and decide what code to execute next. Note the unusual syntax for this IF statement. When all put together this means that if the user enters the text "OMG", the following command is executed:.
They would still have to press enter though. Hi Peter, yes that would work as long as you get the syntax correct.
You need quotes around the text you are matching with, and a colon before the label to go to, so you would use not tested. Name required. Email required. Inane Coding Go on, slap that wayward code.

One is for parameters which can be passed when the batch file is called and the other is done via the set command.
Batch scripts support the concept of command line arguments wherein arguments can be passed to the batch file when invoked.
Following is a screenshot of how this would look in the command prompt when the batch file is executed. Following is the syntax of the set command. In the above code snippet, a variable called message is defined and set with the value of "Hello World". In batch script, it is also possible to define a variable to hold a numeric value. All of the arithmetic operators work in batch files. The following example shows arithmetic operators can be used in batch files.
In any programming language, there is an option to mark variables as having some sort of scope, i. Normally, variable having a global scope can be accessed anywhere from a program whereas local scoped variables have a defined boundary in which they can be accessed.
Create Batch Input
DOS scripting also has a definition for locally and globally scoped variables. By default, variables are global to your entire command prompt session. The following example shows the difference when local and global variables are set in the script. If you have variables that would be used across batch files, then it is always preferable to use environment variables. Following is an example of an output.

For example, I'd like to accept a process ID from the user, and then run jstack against that ID, putting the results of the jstack call into a file. However, when I try this, it doesn't work. I am not sure if this is the case for all versions of Windows, however on the XP machine I have, I need to use the following:. Without the prompt string in quotesI get various results depending on the text. If you need to prompt for an environment variable that will survive reboots, you can use SETX to store it.
A variable created by SETX won't be usable until you restart the command prompt. This procedure allows you to use the temporary SET-created variable during the current session and will allow you to reuse the SETX-created variable upon reboot of the computer or restart of the CMD prompt. I have a little cmd I use when preparing pc to clients: it calls the user for input, and the rename the pc to that.
You did put it in the code and forgot to tell us in the question but when you ran the batch file you hit the Enter key instead of typing an ID say What's happening is the result of these two mistakes: jstack is supposed to be called with the id that you supply it. But in your case according to the code you supplied in the question you called it without any variable.
You wrote:. Your second mistake is that you pressed Enter instead of giving a value when the program asked you: Enter ID:. But you did NOT supply a value and instead pressed Enter. Jstack itself echoed the input, encountered a mistake and asked to terminate.
And all this was written into the jstack. Dollar signs around the variable do not work on my Vista machine, but percent signs do. Also note that a trailing space on the "set" line will show up between the prompt and user input. It now shows me the location I respond as the point for that sample. Looking for clear air, I can eavulate the lowest use channels and whether there are 5 or just all 2.
Just to keep a default value of the variable. Press Enter to use default from the recent run of your. In the first run just ignore the message about lack of file with the initial value of the variable or do create the Var1.

Most recent answer. Faris Baker. Computations are normaly made in batches. The higher the batch size, the more memory space you will need.
Very big batch size may not fit into memory and takes a long time to be trained. The disadvantage it is less accurate. Let us say you have training samples. If you select batch size asthe algorithm takes the first samples 0 to from the training dataset and train the network, then the next samples to and train the network again until the end.
Popular Answers 1. Konstantinos Kontakis. Hellenic Mediterranean University. From my experience with Keras and assuming you are familiar enough with neural networks:. Each batch trains network in a successive order, taking into account the updated weights coming from the appliance of the previous batch. This value can be useful for networks conforming with an RNN architecture. It is widely used in stacked LSTM networks.
Concerning your last inquiry, I suppose that the smaller batch size eased the overall computational cost -while at the same time- the classification accuracy of your dataset was improved due to the increased number of weights' updates. However, the performance and accuracy of your tested network also depends on various other parameters like its dataset size, learning rate, momentum, etcso don't take for granted that a smaller batch size will always wield better results compared to a higher one a rather small size may 'generate' noise and lead to bad training.

If you see the comment " the sample of index i in batch k is the follow-up for the sample i in batch k Can you help by adding an answer? Related Publications. Full-text available. Sep Sometimes we need some user interaction in our batch files. We may need to know to which directory a file is to be copied, for example.
Or which drive needs to be formatted. How you can manage to retrieve user input depends on the OS version used, and whether you want to allow "third party" tools or use "native code" only. This command will display an optional promptString where the user can type in a string and press Enter. The typed string will then be stored in the specified environment variable variable. Duke Communications International, Inc. My own DialogBoxes executables, written in C can be used to display messages and ask for input in Windows XP and later versions.
Walter Zackery posted two interesting solutions to obtain user input in NTon the alt. It will actually change drive C:'s volume label and then restore it again to its old value. Besides that the batch file limits the string to 2 words 1 space only. I adapted the original postings so that the batch files no longer need to use temporary files. You can view the original postings at my Solutions found at alt.
Another great solution by Eric Phelps uses a temporary HTA file to obscure a password while it is being typed. BAT and N. Guess what happened if a user typed a completely different answer. Many PC users and batch file authors including myselffind this approach "less intuitive", to say the least. One would expect that pressing the enter key is enough, and once you find out it isn't, the previous line of input cannot be removed anymore.
The previous example is only a bare minimum. COM is loaded. With a few minor adjustments replace. BAT with. The following batch file checks if ANSI. SYS is loaded. If so, it will tell the user to press the Enter key only. If not, it will tell the user to press F6 first, followed by the Enter key. However, to check if ANSI. There are many batch utilities on the web that help ask for user input.It is a technique for mass input of data by simulating user inputs in screens of existing transactions.
Screens are not displayed, it can be run in the background.
You do not bypass any of the standard SAP consistency checks, authorizations, etc. Both must be programmed in an ABAP program. Then embed the recording into your program, then trigger it by using either CTU or BI session method.
All screens are displayed. On each screen, a little popup is displayed with the next recorded function, the user has to press Enter to execute it.
By default, screens are not displayed, except if an error occurs, or if the end of BDC data is reached although the recorded transaction was not exited.
Same as N. Since the new debugger has been introduced, mode P is more or less obsolete. Local update task. If the client is not open then export the shdb recording and import in the client which is open and then generate program or function module.
Don't be afraid to directly change the page as you see fit. I tried with your comment, but you may have a better way and can go in and change it. ABAP Development. Browse pages.
