Sharing data between two separate user sessions

Hi all!
I have been trawling my brain for a solution to this - any help will be appreciated!
I would like to create a single instance of a class but share that instance over more than one user session (two separate users but both running concurrently).
Just as you can pass data between sessions using ABAP memory - I would like to pass data (specifically an object reference) between two separate users that could even be logged in to two separate application servers...
Even a mini Client/server solution would suffice but I cannot figure one out!
Is this possible?
Many thanks for your thoughts in advance...

Hello N K,
sorry thats not possible. Sharing a data item / object instance requires at least a common physical memory. As this is not guaranteed between different app. server this is technical not possible.
With release 640 ABAP offers the new feature Shared Objects. These mechanism allows access by different users and some propagation to differnt servers.There is an interesting article on the ABAP SDN homepage
https://www.sdn.sap.com/sdn/developerareas/abap.sdn
For relases below more or less the database is the only chance to store data accross application servers (known to me). One exception might be the ENQUEUES which might (mis)used to store some Flags.
Kind Regards
Klaus

  • Sharing data between two canvases on the same form ?

    Hello,
    I have one form with two canvases and two data blocks.
    Datablock A and datablock B are same tables.
    The reason I split is so I can have a search field on canvas A, then after executing the query, I want to populate canvas B.
    I'm having trouble sharing the data across both data blocks.
    Note: I set up a relation in datablock B to correspond with A, and I've chosen field name "Horse" to be my master and detail item.
    "When-button-pressed-trigger" --> Here is part of my code after the user presses the "Search" button (in datablock A).
         execute_query;
         SHOW_VIEW('CANVAS_HORSE');
         HIDE_VIEW('CANVAS_SEARCH');
         :fox_horse.horse := :fox_horse1.horse     ;                         GO_BLOCK('FOX_HORSE');
    When I go back to my "FOX_Horse" datablock, why is the :fox_horse.horse field the only one populated? I though by creating a relation btwn the two blocks they would syncronize automatically ?
    Any advice ?
    Thanks,
    Bob

    Alex,
    I have tried your suggestion, yet I'm still having a problem once I issue my execute_query command.
    In my Search button I have this code:
    BEGIN
    :fox_horse1.horse := :fox_horse.horse;
    GO_BLOCK('FOX_HORSE1');               
    execute_query;
    END;
    Note that FOX_HORSE is NOT a database block (as you suggested), but FOX_HORSE1 is a database block.
    So when I click on the "Search" button I can see the :fox_horse1.horse field getting populated immediately, but then the system asks me if I want to save changes. When I say NO, the actual data block portion of my screen just defaults to the first record, so my exec_query show no effect at all.
    What am I doing wrong in my search button trigger ?
    Thanks so much for your advice,
    Bob

  • Sharing data between two Web Apps

    Hi,
    I have got two web applications that share a MySQL database accessed by
    Kodo JDO. I have tremendous difficulty to share the state that one web
    application writes to the database with the second web application. The
    data seems to stay in the cache of the first app and I have not found a
    way to flush the data to the SQL database, so that the second can read it.
    I do a refresh on the relevant object within the second app. The problem
    seems to be flushing the cache of the first app.

    Hi Greg,
    this:
    properties.setProperty("kodo.DataCache", "false");
    does not do the trick. There is no difference in behaviour. To use
    kodo.RemoteCommitProvider I would need the performance pack at 900 bucks a
    pop, which is not an option right now.

    Are you using Kodo's Datastore cache in both web apps? I suspect that what
    is happening is that the data actually is being flushed to the database
    appropriately (assuming that you commit your transactions), but that your
    cache in your second app has stale data. Could you turn off the datastore
    cache in both apps just test that hypothesis?
    If your applications start to work as expected with the datacache off, then
    you should check out (assuming you're using Kodo v. 3.1.3)

  • Use of SAP memory to transfer data between two different sessions.

    Hello experts,
    I wish to know how to use SAP memory to transfer data between two different sessions.
    The scenario is that when I run a report and change a variable, the value of changed variable should be availabe to another user on another terminal.
    Thanks & Regards!
    Sumit

    Hello,
    Just to add what Max has already mentioned. IMPORT TO / EXPORT FROM DATABASE statements can be used to store data in special "cluster" tables (you can't use any DDIC table) e.g., INDX.
    @OP: You can opt for Shared Memory(SHM) for this specific requirement as well. In my opinion SHM is a bit tricky to code, but it is easier to monitor. The opposite holds true for "data clusters".
    You should remember SHM is app-server specific. So if you've a load balancing scenario, using SHM can cause problems.
    Hope i'm clear.

  • How to pass data between two internal sessions using ABAP memory?

    Hi,
    How to pass data between two internal sessions using ABAP memory?
    It would be fine if you could explain with an example.
    And also let me clear about the data passing between two main sessions and two external sessions with specific examples.
    Thanks.

    Hi ,
      check the example.
    Reading Data Objects from Memory
    To read data objects from ABAP memory into an ABAP program, use the following statement:
    Syntax
    IMPORT <f1> [TO <g 1>] <f 2> [TO <g 2>] ... FROM MEMORY ID <key>.
    This statement reads the data objects specified in the list from a cluster in memory. If you do not use the TO <g i > option, the data object <f i > in memory is assigned to the data object in the program with the same name. If you do use the option, the data object <f i > is read from memory into the field <g i >. The name <key> identifies the cluster in memory. It may be up to 32 characters long.
    You do not have to read all of the objects stored under a particular name <key>. You can restrict the number of objects by specifying their names. If the memory does not contain any objects under the name <key>, SY-SUBRC is set to 4. If, on the other hand, there is a data cluster in memory with the name <key>, SY-SUBRC is always 0, regardless of whether it contained the data object <f i >. If the cluster does not contain the data object <f i >, the target field remains unchanged.
    In this statement, the system does not check whether the structure of the object in memory is compatible with the structure into which you are reading it. The data is transported bit by bit. If the structures are incompatible, the data in the target field may be incorrect.
    PROGRAM SAPMZTS1.
    DATA TEXT1(10) VALUE 'Exporting'.
    DATA ITAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
    DO 5 TIMES.
      ITAB-BOOKID = 100 + SY-INDEX.
      APPEND ITAB.
    ENDDO.
    EXPORT TEXT1
           TEXT2 FROM 'Literal'
      TO MEMORY ID 'text'.
    EXPORT ITAB
      TO MEMORY ID 'table'.
    SUBMIT SAPMZTS2 AND RETURN.
    SUBMIT SAPMZTS3.
    The first part of this program is the same as the example in the section Saving Data Objects in Memory. In the example, the programs SAPMZTS1 and SAPMZTS2 are called using SUBMIT. You can create and maintain the programs called using the SUBMIT statement by double-clicking their names in the statement. For further information about the SUBMIT statement, refer to Calling Executable Programs (Reports)
    Example for SAPMZTS2:
    PROGRAM SAPMZTS2.
    DATA: TEXT1(10),
          TEXT3 LIKE TEXT1 VALUE 'Initial'.
    IMPORT TEXT3 FROM MEMORY ID 'text'.
    WRITE: / SY-SUBRC, TEXT3.
    IMPORT TEXT2 TO TEXT1 FROM MEMORY ID 'text'.
    WRITE: / SY-SUBRC, TEXT1.
    Example for SAPMZTS3:
    PROGRAM SAPMZTS3.
    DATA JTAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
    IMPORT ITAB TO JTAB FROM MEMORY ID 'table'.
    LOOP AT JTAB.
      WRITE / JTAB-BOOKID.
    ENDLOOP.
    The output is displayed on two successive screens. It looks like this:
    and
    The program SAPMZTS2 attempts to read a data object TEXT3 from the data cluster "text", which does not exist. TEXT3 therefore remains unchanged. The existing data object TEXT2 is placed in TEXT1. In both cases, SY-SUBRC is 0, since the cluster "text" contains data.
    The program SAPMZTS3 reads the internal table ITAB from the cluster "table" into the internal table JTAB. Both tables have the same structure, namely that of the ABAP Dictionary table SBOOK.

  • How to separate data between two colons

    Hi,
    how to separate data between two colons?
    ex: 'ABC:1234:1-ss-2:0:0:0:0-DEF:5678:0:0:0:0'
    how to access these 1234, 5678 and 1-ss-2 ?
    there may be any string.

    Hi,
    The string 'ABC:1234:1-ss-2:0:0:0:0-DEF:5678:0:0:0:0' contains 11 colons, and 10 sub-strings that are between colons. How do you distinguish the ones you want,
    (1) 1234
    (7) 5678
    (2) 1-ss-2
    from the ones you don't want
    (3) 0

  • How to compare data between two tables?

    Hi,
    My team is trying to develop a SAP data migration tool (DMT) using ABAP.
    One of the functionalities in the DMT is to validate the data in the staging area against the loaded SAP data.
    The tables in the stagin area are customer tables (i.e. user-defined tables starting with Y, Z).
    How do I compare the data in the staging area against data that are loaded into SAP tables? Are there some built-in SAP functions to do this? Or, are there some better ways of doing this (e.g. instead of comparing against data in the SAP tables, we compare with some INTERNAL tables)?
    Any help would be greatly appreciated, thanks!

    Hi Kian,
    Use <b>SCMP</b> transaction to compare data between two tables and you can not use this for comparing internal tables.
    Thanks,
    Vinay

  • Does time capsule backup two separate users with their individual passwords or how do you set that up?

    I Have two separate users on my computer and want the backups to reflect that. I don't want one user to have access to my stuff and vice versa.  Does time capsule do this automatically or do you set this up somehow?

    TM does the whole computer.. it is designed for home setup.. where people not that worried about security.
    It is always possible for any user to access any other users account.. given enough time and skill. TM backups make it easier in a way.. I have tested it myself and I can recover TM backups from unknown user in a Time Capsule with an unknown password. It was tricky but anyone with brains can read the net.
    There are solutions.. as I said.. if you are worried you should be using Encryption. Never depend on passwords in a shared computer to prevent access.
    If your files are encrypted then even if a person recovers them they cannot read them without the key.
    It may need for your files to be on a separate partition.
    See Pondini's info on file vault and interaction with Time Machine.
    http://pondini.org/TM/25.html
    Of course for a person to hack in.. they have to want to do it.. in most people's home situation that is not a hassle.
    For a business setup you would be using superior security.. proper active directory server etc.

  • HT204053 Is it possible to sync calendars between two different users?

    Is it possible to sync calendars between two different users?

    Hi
    Installing the drive into the older machine may work, you WILL get a lot of driver errors and the unit may even fail to boot. The other problem is that the drives may not be compatable, the drive in the broken PC is a SATA drive, older PCs had IDE drives with very different connectors.
    Your best option is to do as you suggest and obtain a USB caddy and extract the data that way.
    Make sure that the caddy you get will support SATA drives (all new ones will).

  • How can I share data between two forms on different lists

    Using a custom content type, I created two lists that I want to share the same data - one is a calendar.  Our employees complete a form from the "Out of Office Request" list that has workflow functionality that sends an email to that person's
    manager.  If the manager approves the request, the item automatically populates the "Out of Office Calendar."  The problem is that the only information from the request list that populates the calendar is the Title field and date/time fields. 
    I need the manager name in order to create a view for each manager.  
    How can I connect the other information in the request list to the calendar list.  It seems to me that if the title and date fields carry over the information, there should be a way to connect the other information.  I'm using Designer.
    I've tried to connect the two lists' webparts with the wizard, but when I get to the page that maps the two lists, there are no column names and the "Next >" button is grayed out.  This seems like the logical place to connect the two lists,
    but it isn't working.

    Hi,
    According to your post, my understanding is that you wanted share data between two forms on different lists.
    To show external  information on the calendar event, there are two methods: Calculated column, workflow. You can refer to:
    A Simple Guide to Show More Information on a Calendar Event
    I recommend to use workflow to achieve what you want. But you need to create a people column to display the manager.
    You can create a workflow associated to the "Out of Office Request" list, add action to Start Approve Process. If the manager approves the request, you can create a item in the calendar, and then update the people column and the title column.
    Then the calendar will display the Title, date/time and the manager.
    To create a view for each manager, you need to modify the Filter. You can use the people column is equal to the manager name or the Title contains the manager name.
    Thank you for your understanding.

  • Can I transfer Time Machine data from two separate hard drives into one new one?

    I'm using a MacBook Pro as my primary computer.  My 500 gig Time Capsule filled up a year or so ago, so I stopped using it with Time Machine for awhile so I could keep the data from those old back-ups.  There were a number of things I deleted from my computer's very limited hard drive after they were backed up to the Time Capsule.  I got a 1T external USB drive last year to use as my "filing Cabinet" to store files I didn't necessarily need all the time or that were filling up my small laptop hard drive--including my iTunes library--all organized in a way that made it relatively easy for me to find what I needed, even if I didn't remember exactly when I'd filed it or what I'd called it.  I got another 1 terabyte external (portable) drive last July and dedicated it to TimeMachine backups and labeled it "TimeMachine".
    Over the last couple of weeks, my friend has been helping me upgrade to Yosemite and clean up my laptop hard drive.  Last week he cloned my laptop hard drive to a new 1T hard drive and I exchanged it for my old drive in my computer today. All good.
    Here's the issue.  We replaced my Time Capsule hard drive with a 1 terabyte drive with the idea of transferring the data from the old Time Capsule (500G) drive and the newer USB 1T "TimeMachine" compact drive to the new 1T Time Capsule drive and beginning using the latter for my Time Machine backups going forward.  Originally he thought we could copy everything from each of my external drives (the old 500gig drive from my Time Capsule, the USB "TimeMachine" drive I've been using since July, and the "file cabinet" files) to my computer in their own folders and then start regular TimeMachine backups to the new Time Capsule drive, thus preserving all my old data and making regular backups going forward.  The "file cabinet" data was no problem at all, but when I tried to copy my USB "TimeMachine" data to my computer, I was unable to.  My friend found instructions for transferring old TimeMachine data to a new TimeCapsule, but I don't know if I can transfer the data from two separate disks to the new TimeCapsule drive. I'm afraid that one set of data will supersede the other and either my newer backups or my old ones will be lost if I try to transfer both. 
    Are my fears justified or is there a way to insure that no such problem will occur?  Of course, my data will still be on those two older drives, but that won't do me a lot of good if I can't access it when I need to. Also, the 1T drive now belongs to my friend; he used a brand new drive he'd bought for himself for my new internal hard drive and plans to take my 1T "TimeCapsule" drive in exchange, once the data has been transferred, so he will, of course, erase that drive. 

    Should we be able to bring up the old (500G) Time Capsule Drive to rename it using a SATA to FireWire harness and then copy the whole thing to the new Time Capsule drive?
    You can copy a whole sparsebundle from one drive to another. That is not a problem. Whether you can access the sparsebundle is something you should test before you even start though.
    If it's on the Desktop and I don't tell Time Machine to exclude it from backups, will it just automatically back it up?
    All drives you plug into the Mac are excluded by default.. you must include them. So no problems there.. but I hope I am understanding the question.
    Will both volumes or directories (which is the right term?) show up when I open Time Machine?
    No, Time Machine will only open what it is told to open... or its backup default location.
    You can force Time Machine to open alternative/old/no longer used backups by (now I have a problem as things have changed somewhat in Yosemite and I consider it alpha release software at this point in time). The old method was to right click on the TM icon and select a different TM backup. easy. Yosemite seems to have made easy stuff harder.
    Here it is on my current computer.. clearly not Yosemite.. Right click on the TM icon in the dock.. select Browse Other Time Machine Disks.. And supply the info of where that is located. Easy. If you cannot figure it out one of the other posters here (with more patience than me for Yosemite) will help you.
    Or will we have to partition the new drive somehow--is that even possible?
    I am getting more lost as I go down the list.. but the TC disk cannot be partitioned.
    If you have included all those USB drives in the new backup on a Time a Time Capsule.. you have made life rather hard because now your files are stored another layer deeper than they were.
    So to open a file from a disk you need to open the sparsebundle.. then dig down to the drive in question and then dig down to the backup.. and all of this means Time Machine has to work perfectly which is Yosemite is a very big ask.
    I thought you wanted to just backup your old drives to central location.. which means copying the files to a separate folder on the Time Capsule.
    One correction I need to make to my post, which will make my strategy make a bit more sense: my new Time Capsule drive is 4T
    It makes it much harder.. and I have to pose a real question of long term .. if you have put a 4TB drive in a Gen1 TC.. did you also replace its power supply because I can assure you the drive might be ok but the TC itself will not last forever.. and what happens when it dies. The Gen1 power supply is already well beyond its normal life span and the vast majority are dead. When the backup device is unreliable and the backups on it are made that much harder to get access to.. is this a great plan??
    If you are going to consolidate all your old files on one disk.. a task I find understandable. I have done much the same albeit the usefulness of files made on emac running OS9 may be questioned. A disk lying in the bottom of a draw is a more appropriate place for them.
    You want those files as easily accessible as possible (at the point of recovery) and not buried inside a sparsebundle.. particularly not a sparsebundle from the old TC disk buried inside a new sparsebundle.. keep files as accessible as possible as you can run searches.. and that is best done on a USB 3 (or faster ie thunderbolt) drive plugged into a new(ish) computer.. not network. And since the files are not being accessed on a daily/weekly or even monthly or yearly basis.. keeping them in actively running TC network storage.. I would say is a waste of space. That is only my opinion of course.. you might consider it highly important that files you will never look at are available any time of day or night when the urge comes to track down that elusive pimpernel email you sent 10 years ago... but I find it hard to justify. What the case.. the problem with TM and things like Mail is you cannot search it.. you must restore the whole library/files/program even before you can access it.. that makes file recovery out of a sparsebundle double step process.
    So.. summary.
    If you want to store files on the 4TB drive in the TC.. that is not a great strategy but it can work.. simply create a folder named.. OldFilesEMac for instance.. and do a simple copy and paste of all the file to that location. Do not use TM.. Since you have already used TM.. and from what I am reading you have already done the backup with the external drives included.. then you are going to end up needing to erase the TC and start over.. which you may not be prepared to do.. which is fair enough. (I am coming across as overbearing school master.. apologies).
    TM is to backup your main OS and current files.. not files from 10-20years ago.
    Please do read the issues involved in Pondini..
    See his FAQ. I recommend you read through Q14-17 so you understand what is involved in recovery.

    Particularly so you understand the complexity of Time Machine.
    And the articles here. http://pondini.org/TM/Time_Capsule.html

    I wish I could spend an hour or two face to face and work it out.. the whole strategy to do this.. !!
