Advice for Session Handling

I'm in the process of constructing a second application, and have once again faced the same problem I've faced in the past.
Session Handling. One thing That I'm very concerned about is people using the Browser Back Button. Unfortunately when people use the back button the page they see is not coming from the server, but from their browser's cache. This means that the session info that they see is not up to date. In both my applications this would lead to some seriou problems.
Any suggestions as to how I can either remove the Browser's Back button, or have the servlet refresh when the back button is pushed. Any other suggestions wouls also be greatly appreciated.
Thanks,

Hi
It would be very helpful if you can present a scenario in your application where the back button usage would cause seroius problems.
Technically speaking you cannot remove the back button. But what you can do is through Java Script open browser windows where the back and front button's tool bar is not visible, but note that the user's can still use the keyboard to move back and forth.
As far as session handling is concerned you would have to take all the worst case scenarios while designing your web application like the browser crashing, user's closing their browser windows without explicit logout, a database transaction not going through etc.
Present a scenario of your application so that the session handling mechanism may be discussed.
Good Luck!

How to use bsp application SYSTEM for session handling.

Hi All,
We are implementing OCI.We have a few BSP applications that are called by standard ITS application.I need to destroy session at server side when the browser is closed for that..
I copied the pages session_default_frame.htm and session_single_frame.htm from bsp application SYSTEM into my application and made necessary changes.
I need to pass one url 'HOOK_URL' (this is related to OCI) from starting page of application to final page.
Now suppose earlier there were two pages in my application page1.htm and page2.htm , so i was able to pass the HOOK_URL from page1 to page2 but after adding the two pages from SYSTEM application , i can pass the HOOK_URL from session_single_frame.htm to page1.htm
Page session_single_frame.htm:
Page attributes:
hook_url     TYPE     STRING (AUTO)
OnRequest:
navigation->set_parameter( hook_url ).
but cant pass it from page1 to page2...what additional code is required?
page page1.htm:
Page attributes:
hook_url     TYPE     STRING (AUTO)
onRequest:
navigation->set_parameter( 'HOOK_URL' ).
the above code was working fine until i added the two new pages to my application.
Hope i was able to explain the issue properly.
Thanks,
Anubhav.

Hi,
Let me describe the steps i have taken oncw again:
1)Copy page session_single_frame and session_default_frame from SYSTEM application and changed the name in
DATA: target_page               TYPE STRING VALUE 'session_test.htm'.
to
DATA: target_page               TYPE STRING VALUE 'mypage1.htm'
2)Addes a page attribute HOOK_URL of type string (AUTO) to session_single_frame.htm .
3)Added the line
<i n p u t t y p e="hidden" na m e ="HOOK_URL" v a l ue = "< % = hook_url %>">
to page1.htm so that hook_url is passd to page2.htm (page2.htm has a page attribute HOOK_URL of type string and auto).
The hook_url in page2.htm looks like:
"http://sapupd.mycompanyname.com:8002/sap(cz1TSUQlM2FBTk9OJTNhc2FwdXBkX1NSTV8wMiUzYXJUaHBOdE1VZDdhWkVTa3hYZGtPTXRxY1NBTWo3VlAwN3NWQ2c2REYtQVRU)/bc/gui/sap/its/bbpsc02/?~OkCode=ADDI&~Target=_top&~Caller=CTLG&~sap-syscmd=NOCOOKIE&~client=200&~language=EN&~HTTP_CONTENT_CHARSET=utf-8";
The problem is that after the page is submited , a blank page comes up .
On closing this blank page the "Endig user session" window comes.
Please help
Thanks,

Configure no. of session handled for same sql

hi, experts,
hi, if there is one report (only fire 1 sql by this report).
if only one internet explorer to run this report , it use 3 minutes to get it.
I use 3 internet explorers to run the same report but not running the report at the same time.
firstly, I run the report on first internet explorer.
then after 10 seconds, I run the report on 2nd internet explorer.
then after 10 seconds, I run the report on 3rd internet explorer.
after result on all internet explorer came, I check the sessions on the "Manage Sessions"
there are 2 sessions for same report.
How to configure no. of session handled for same sql on OBIEE?
thank you very much!

The v$session views shows current sessions (which change rapidly), while the v$resource_limit shows the maximum resource utilization, like a high-water mark.

Error - session handle nor valid for ivi

Hi All
I have posted this question in existing thread also I guess.
I am trying to control TDK lambda power supply through LabVIEW using IVI drivers.
logical name set in a MAX is same as what I am giving in VI to InitializeWithOptions.vi . However I am ending up with this error "IviDCPwr Initialize With Options.vi<ERR>
Primary Error: (Hex 0xBFFA1190) The session handle is not valid."
Not sure why this error is coming.
Can anyone help me with this error?

You might be using an IVI-COM driver and trying to use IVI-C Class driver VIs without having installed the IVI-COM adapters.
As mentioned in the knowledge base below The IVI-COM adapters are included with IVI Compliance Package 3.2 and later, but must be enabled in the installer's feature tree.

Implementation of session handling for using web services

Hi,
I would like to use session handling in web services using ABAP stack in order to start the session with an user login function followed by other RFC calls till a user logout. So far, I found only the following help note in the SAP online help:
Interface Profile
In the interface profile, choose the required processing type: Stateful or Stateless.
A stateful service retains its status within the framework of a HTTP session throughout several calls form the same service consumer. The standard value for services is Stateless.If you require stateful communication, you can choose this instead.
[http://help.sap.com/saphelp_nwpi71/helpdata/de/45/25291b5a2657c0e10000000a1553f7/content.htm |http://help.sap.com/saphelp_nwpi71/helpdata/en/45/25291b5a2657c0e10000000a1553f7/content.htm]
Please, could someone explain me the further required steps of SAPs session handling idea cause just settting the status to stateful is still not the solution itself...

Request Advice for creating DVDs from 7.5 gig file sizes

Hi,
[using dvdstudio 3]
I’m looking for advice for home DVD project i'm working on. I want to create a DVD from video that has been captured to my computer using iMovieHD, and have completed my wanted edits for two clips. They are about an hour-plus each. When exporting the two clips separately (Sharing, in iMovie terms), the file sizes are about 7.5 Gig each at full quality,and I understand I’m going to have to cut some corners in the process to get both on one DVD and I’m even willing to have two DVDs, but still need to know the best way to decrease the file size for each one. The audio should remain as 16 bit 44.1 Khz, Stereo.
I’m wondering what the best method to achieve an optimum quality DVD is. Again, I realize I’ll have to compress the video at the loss of quality (i.e., “cut corners”) to make the DVDs.
In my previous experiences, I’ve retained the larger file size all the way up through the authoring process in DVD Studio letting it build a 7.5 gig dvd format (VIDEO_TS). Then, I used DVDx2One to compress it down to 4.5. The end result was pretty good and I never had any troubles per say. However, this project is important to me and I want to make the best quality I can. What would you do differently?
Here are my software tools that I use interchangeably for previous projects; copying, authoring, editing, etc:
-> iMovieHD 4x – used to capture the video.
-> DVD Studio 3 - to author and build my dvd session
-> ffmpegx - as a video conversion and compression tool
-> DVDX2one to recompress DVD formatted (VIDEO_TS).
Thanks very much for your tips!
JeffTronics

Hi Jeff - is the iMovie file in QT format?
If so, you need to compress it to MPEG2 - you don't need to suffer too much of a quality loss by doing so - how long (in minutes) is the video?
You should also encode the audio to AC3 - this will save loads of space as AC3 is about a tenth the size of a .aiff.
ffmpeg will create the MPEG for you, but so will DVDSP (as indeed will Quicktime). In your applications folder you should find 'A.Pack' which will handle the audio conversion as well.
The exact encoding parameters you use will depend on the nature of the footage that you have got - it's more than just squeezing it to fit - you need to account for fades, pans, zooms and fast action as well. Some parts can have a lower bitrate applied than others, and this is where a tool such as Compressor comes in handy. DVDSP will encode the footage as you work, or when you build if you want it to - this is also a reasonable option if you have nothing else available, or if you are new to the whole thing.
The best workflow is to go from iMovie to a compression tool to create your MPEG2 file. Take the associated .aiff file and encode to to Dolby Digital (AC3). Import both the MPEG2 and the AC3 file into DVDSP and you should be able to get the entire project to less than 4.37GB (the maximum capacity of a DVD-R).

Automatic creation of remittance advice for employee expense reimbursements

Hello experts
Is there a way to have remittance advices for employee expense reimbursements created automatically at the time of payment media run? In case of suppliers, in the supplier base you can heck "Advice Required" and then at the time of media run the remittance advice can be generated alongwith the payment. Is there a similar setting that can be done for employees?
Thanks
Gopal

Hi
Just to follow on from Ravi's reply: most sites that I work at have the report RPRAPA00 scheduled to run on a periodic basis (define the job via transaction code SM36) to automatically create employee's vendor accounts. A screen variant is usually saved for the program, and then the batch session is monitored on a regular basis to ensure that it has run successfully.

When we have to go for session method, when we have to go for call transact

when we have to go for session method, when we have to go for call transaction method if i have a 3000 records in flat file. which is better? why

Data Transfer
During the process of data transfer, data is transferred into the SAP R/3 System. This transfer is from an external system to SAP R/3 system. Whenever you transfer data from an external system into an R/3 System, you can use data transfer because it is installed and regularly transfers data from an external system into an R/3 System.
As discussed, with the help of BDC, you can transfer the required data from a non-SAP system to an SAP system. For this kind of data transfer you are required to write an ABAP program. This ABAP program would help to export the concerned data to a sequential dataset file. The data in this file has to be stored. This should be stored in a format, which is acceptable to SAP batch input program. But, to transfer data from a SAP system to another SAP system, you can take the aid of RFC or CPI-C.
SAP application supports the data transfer of numerous SAP business objects. The said data transfer program specifies the data format definition, which is necessary to import the data into the R/3 System. There are three methods available for transferring data:
Direct Input:
In this method the SAP function modules execute the consistency checks. However, there are other means of checking with the help of screens. The Direct Input Method has considerable performance advantages.
Call Transaction:
In this method you can check the data consistency with the help of screen logic.
Batch Input Session:
In this method data consistency is checked with the help of screen logic.
Direct Input Method
Among the methods of data transfer through BDC, direct input method is the one that is used, especially in case of transferring large amount of data. In order to enhance the batch input procedure, the system offers you with the direct input technique.
There is a distinction between the batch input technique and this technique. Unlike batch input technique, this technique does not create sessions. Instead, it stores the data directly. Moreover, it does not process screens. The data has to be entered directly into the corresponding database tables. The system calls a number of function modules which execute necessary checks, if any required. In the case of errors, the direct input technique has a facility to restart the entire mechanism. However, if you want to restart the entire mechanism in case you faced an error, then direct input programs must be executed in the background only. One has to use program RBMVSHOW or Transaction BMV0 to maintain and start these programs.
Call Transaction Method
Call Transaction method is another method used for Data Transfer. In this type of method your program will use the ABAP statement CALL TRANSACTION USING in order to run a SAP transaction. In this type external data need not be deposited in a session for being processed later on. Instead, the entire batch input process takes place inline in your program.
Here, the data transfer program must convert the data that has to be transferred into the SAP system. This is as per requirement by the SAP data structure or the transaction which is using it. It is to be remembered that a conversion of the data types may be necessary at different times during the process.
Suppose there is a data type mismatch then you have to convert the data types to type C. In this regard the data transfer program should be capable of exporting the data in SAP format to the sequential file. At the time of uploading the data into the SAP system, the BDC program reads the data from the abovementioned sequential file.
Batch Input Session Method
This is the third method for data transfer. If you use the batch input method to transfer data, then you should remember that an ABAP program has to read the external data which is to be entered in the R/3 System. Subsequently, it stores the concerned data a "batch input session." The batch Input session records the actions which are required in the process of transferring data into the system. This can be done by using normal SAP transactions.
As soon as the program generates the said session, you will be able to run the session in order to execute the SAP transactions in it. Moreover, you can start the session, and at the same time, can monitor a session with the help of batch input management function. For this you have to choose:
System à Services à Batch input. Moreover, you can have the session run in the background processing.
Writing a Data Transfer Program
If you want to write a data transfer program, you have to follow the steps mentioned below.
Firstly, you will analyze the structure of the existing data. Subsequently, your job is to specify the conversions, which are essential to fill the SAP data structures.
Secondly, you have to generate the SAP data structure. In case the program is written in ABAP, you will require only the required tables in the concerned program with the help of TABLES statement.
Thirdly, you will have to initialize the SAP data structure.
Fourthly, fill the structure with data, performing any conversions and error checking that are required.
Finally, you will write the sequential file. In the SAP system this sequential file is typically required for making the data available to the batch input program.
Batch Input Method
Batch input method is a type of data transfer method. It is used for bulk data transfer; it is one of the primary ways by which data can transferred into the R/3 System. This method is not for near real-time data transfers.
There are various typical uses of batch input. One of the ways includes the one-time import of data. This import of data is from a legacy system into a newly installed R/3 System. In addition to it, another typical use is for periodic (i.e. hourly, daily..., and so on) transfers of data. These transfers are from external systems or legacy systems which are still in use into R/3 system where all enterprise data is consolidated.
The R/3 applications deliver different programs for batch input, which are ready to be used. However, in some cases a customer has to write his or her own batch input program. This is required in order to convert the concerned data from a legacy System or from a proprietary format into an R/3 data format.
The process flows for a batch input are discussed below.
Data Transfer Decision-Making: It is with a decision to transfer data from an external source into R/3 that the process of batch input begins. It is probable that the external source may be a legacy system that is being replaced. A one-time bulk data transfer is foreseen in this regard. Alternatively, the external source may be an external system that is to remain in use. In this case, a regularly recurring bulk data transfer is foreseen.
Setting up Batch-Input for Data Transfers: If R/3 standard one-time or regular data transfers are required, then by means of customizing settings in the R/3 Customizing System in SAP ASAP set up will occur. You must set up custom batch input procedures by hand, which means the system administrator must schedule the data conversion program that creates the batch input session. The system administrator and the batch input programmer must determine the following: how frequently data is made available from the external system, how frequently the conversion program should run, and whether the conversion program runs in R/3 (ABAP program) or in a host system (external program).
Processing Batch Input Sessions: When a batch input session is processed, then the actual transfer of data into R/3 takes place. Little attention is required in processing of batch input sessions by the system administrator. Usually, the starting of batch input sessions is automated by the system administrator. If necessary, the administrators can also start batch input session explicitly from transaction SM35.
Checking Batch Input Sessions: For a system administrator the routine activity is to check daily or more frequently in transaction SM35 whether all batch input sessions have been completed successfully. It is the schedule for running batch input sessions on which the schedule for checking sessions depends upon. For doing this check the R/3 System provides easy-to-use batch input management tools.
Analyzing Errors: It is the duty of the system administrator to analyze the problem if one or more transactions in a session end in errors. Usually, the assistance of the affected data entry specialist or department for this analysis will be needed by the system administrator. In the situation where the problem was caused by incorrect data conversion or incorrect generation of the batch input session then the programmer who wrote the data conversion program may also need to be involved.
Error Handling in Batch Input Method
It is found that most problems usually fall into one of the following two categories discussed below.
In this case either required data is missing from the batch-input session or invalid data has been included in the session. Errors in the data conversion program or the presence of unexpected types of data or incorrect data in the legacy database are the possible external causes of this type of problem. Within R/3, the causes for this type of problem include incorrect or incomplete customizing in an application. For example, a legacy data type may not have been foreseen in the check table entries made in application customizing.
This case mainly includes technical/programming problems. The data is entered by a batch input session by running R/3 transactions non-interactively. Therefore, a typical technical or programming problem is the incorrect identification of one of the data fields in a transaction. Thus, the conversion program may not fill a required data field or may have provided invalid values.
Conclusion
I have gone through the details of batch data communication and various methods used to transfer data. One can make use of BDC to transfer data from a SAP to SAP system. In addition, it can transfer data from a non SAP system to SAP system too. I have discussed the various methods of BDC and the error handling in the respective methods.
Thanks,
Shankar

Again Session-Handling

Hi there, one question about session-handling in JSP.
I'm trying to set attributes in the JSP and afterwards get them back.
No chance! They always vanish! Here is the code:
<%@page contentType="text/html"%>
<%@page import="java.util.*"%>
<html>
<head><title>JSP Page</title></head>
<body>
<%
// Output of Session-Attributes
for (Enumeration enum=session.getAttributeNames();enum.hasMoreElements();)
String name2 = (String)enum.nextElement();
String value2 = (String)session.getAttribute(name2);
out.println(name2+":"+value2);
// Set Attributes that I get from Form!
String name = request.getParameter("name");
String value = request.getParameter("value");
if (name!=null)
session.setAttribute(name,value);
%>
<form action="SessionTest.jsp" method=get>
<input type=text name=name>
<input type=text name=value>
<input type=submit>
</form>
</body>
</html>
Really dont have a clue!
Thx, ToM

Works ok for me:
Couple of suggestions: put the setting code, before the display code.
That way you will see the pair that you just set in session ;-)
Also try this:
Session id = <%= session.getId() %> and see if it stays the same.
If you are getting a different session every time, then its not maintaining the session.
Common cause of session problem is: cookies are turned off.
Either turn cookies on, or use URL rewriting:
<form action="<%= response.encodeURL("SessionTest.jsp") %>">
<%@page contentType="text/html"%>
<%@page import="java.util.*"%>
<html>
<head><title>JSP Page</title></head>
<body>
<%
// Set Attributes that I get from Form!
String name = request.getParameter("name");
String value = request.getParameter("value");
if (name!=null)
session.setAttribute(name,value);
// Output of Session-Attributes
for (Enumeration enum=session.getAttributeNames();enum.hasMoreElements();)
String name2 = (String)enum.nextElement();
String value2 = (String)session.getAttribute(name2);
out.println(name2+":"+value2 + "<br>");
%>
<form action="SessionTest.jsp" method=get>
<input type=text name=name>
<input type=text name=value>
<input type=submit>
</form>

Recreate remittance advices for all payment runs of the day at once a day.

Hello Sap Gurus,
Here we have requirment for remittacne advices , so please find below quey.
1.      Run once a day and recreate all the remittance advices for all the payment runs of the day.
2.       Convert this into PDF format and download to the LAN structure automatically.
3.       This program should be scheduled in batch and have proper error handling to alert a user via email should there be a error in the download as we need to understand immediately if we donu2019t have all the remittance advices on the LAN.
Please provide valuable inputs for the customised program? and is this possible with customised program? or any standard SAP avialable for ths requirement.
Regards,
Raj

HI,
You can create the same via a custom program with below steps:-
(1) Fetch all the payment run IDs from table REGUV for a particular run date.
(2) Then for each run date and run identification combination, call in loop Remittance Advice Printing Program (RFFOAVIS or RFFOAVIS_FPAYM) and it will generate the spool.
(3) Then call the program RSTXPDFT4 to convert the spool into a PDF file and store on SAP aplication server.
Then you can have a interface from SAP Application server to your LAN to have the file transferred.

Gaurav

LabVIEW done right: Requesting advice for a large LabVIEW project

Hello Everyone,
I have been coding LabVIEW for about 2 years now, off and on as my company requires it, and although my coding abilities and neatness have improved greatly since I first started I still end up with large, messy looking programs.
I have a great understanding of SubVIs and use them regularly and often. I am also familiar with the various code structures such as a producer/consumer or state machine. But I keep finding that too much of my main code is interdependent on common variables, indexes, and values that it seems impossible to simplify any of them into subVIs because I would need like 10+ inputs or a custom cluster for each one. This seems counter productive and time consuming.
I have searched far and wide for good programming technique for larger labview programs and I have only been able to find the most basic advice such as "Use subVIs" or "Use a state machine" and all the examples I can find are laughably simple.
I can reduce my program to 3 while loops. One captures Events and gives commands on a queue, another takes those queued items and performs actions, and the third performs data gathering, plotting, and saving once each second. This starts out good, but by the time I've incrementally added all the features my company requires, each loop is a huge interconnected mess of wires with no clear way to section them up into subVIs.
A solution would be to make everything either a global variable or FG but as a native C programmer I was always taught to avoid globals. And if I went the FG route I would need somewhere around 100+ different VIs just to handle them all.
Is there something I'm missing? I want to know how you pass data between the various loops of your program. Do you use one big cluster? Globals? FGs? None of these options seem ideal to me but maybe I'm missing something obvious.
If anyone has any advice for me, it would be well appreciated. Better yet, if anyone has, or could point me to, an example program exhibiting an ideal programming structure for a project similar to the one I mentioned above, I would love to take some time to look it over. Hopefully I'll be able to pick up some good tips and tricks for keeping my main VI to one screen size, and effectively passing all the required data to all the subVIs that require it.
Thanks in advance,
-Aaron

Do you try to identify related information that can be used by a whole set of related subVI's? For example, you might have several parameters related to a specific piece of hardware. These can be grouped into a typedef cluster (or, even better, an object with all the related subVIs part of the object class). You definitely don't want to be using custom cluster for each subVI, but well designed subVI's shouldn't have more than a few custom inputs once related information is grouped.
As for data in the loops, I usually just have one big cluster in a shift register. This is never itself sent into a subVI, but parts of it (the typedef clusters or objects from above) are unbundled and sent into subVI's. It's basically just serves as a cleaner way of holding all the parameters. I'll attach an image of a "state" of the program I'm now working on. There are only a few wires unbundled in each individual "state", even though the full cluster (the top shift register in the image) has 20-odd components (and some of them are subclusters/objects that themselves have many components, such as the "Selected Record" object in the image which itself is a 15 element cluster).
BTW, I'm using the "JKI state machine toolkit" which you might want to look at to get some ideas.

ERP2004: ESS JCO session handling in Web Dynpro apps?

Hello,
we run ESS/MSS Web Dynpro scenarios, running on WAS 6.40, SP12 in
Enterprise Portal EP6 SP2 Patch 32. Our go live will be with > 1000 ESS users.
1. When will the sessions in R/3 backend system be terminated by the
Web Dynpro Application?
How is the session handling in FPM (Floor Plan Manager) implemented?
2. Are there any recommendations regarding the JCO connection settings
in Web Dynpro Content Administrator (Maximum Pool Size, Maximum Connections,
Connection Timeout, Maximum Wait Time) to reduce / optimize the load for the
backend system? I found a documentation in SDN but it is not
specific for ESS / MSS based on Web Dynpro.
Background of questions above: The customer is worry about the load on
SAP R/3 backend side: too much current users in the R/3 backend system,
possibly bad performance etc. because the JCO sessions are open a long time.
Are there any experiences with customers running productive ESS / MSS scenarios
based on Web Dynpro?
Thanks & Best regards,
Daniel

Hi,
1. For best practices on JCO settings follow the tutorial below and do it accordingly for your no of users. YOu might have to do some trial and error procedure.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3103eb90-0201-0010-71af-be6f4a6f61d1
2. For standards, security settings, cache management etc, SAP will give a TODO list after a remote audit of your project.

Session handling in Flex

I am using remote object for the flex and service communication. After multiple time log in and log out , which is done by remote object call also, I am getting different session id for browser and from the client side. Is there any way to restrict this session id conflict

I think you are getting confused by comparing flex
development with jsp serverside development, its completely
different thing,
1. How to pass hidden variables using flex.(In jsp we pass it
throuth hidden field, is there any mechanism similar to that one)
-- honestly, where do you really want to pass hidden field to
? (hidden fields is a hack implemented to overcome the way http
protocol works , in flex you don't need that hack) .
2) you can implement exception routine same way (even easier
in flex) if error occures show this and this page(for example error
canvas. with error mesage thats it,
3) How to do session handling in Flex.
-- question is too vague, do you ave concrete problem that

Regarding session handling in BSP

hi all,
    we have integrated our BSP application to EP 5.o, we have used 'existbspapplication'(used buffered page) function in our default page to handle the sessions.
   and its working fine, but now we have to integrate it to the EP 6.0 and we find the sessions are not terminated, and tend to remain after closing the application manually.
   my question is does portal handle sessions if yes, tried the same(by removing session handling code from default page) but could not get the desired result. is there any other way to handle sessions in EP 6.0
thanks,
raju

Hi,
Did you set the checkbox for portal integration on in the properties of the BSP page?
