SLD: Duplicate Technical System after Installation Number change

We changed the installation number for a system. After this, inside SLD there are 2 entries for this system, with 2 different installation number (new and old). What is the correct procedure to remove   one of the entry (old one).
Please advise.
A proper SAP note would be appreciated.
Thanks

Its ok even if you have forgotten to register to the SLD during installation.We can regaister after installation.Since SLD runs on java engine then if you go to http://<ipaddress or hostname of the server>:5<instancenumber>00/sld
If you go into that you can click on administration button and follow the instructions as in the link.

Difference between technical systems and business systems is that business systems are used in PI/XI.Whereas technical systems are nothing but your ECC , CRM etc.You have to use business systems only when there is a case for connecting to XI/PI.Hope i have answered your quesries if not please let me know.

  • SLD Configuration - Technical System and Business System

    Hello,
    I have installed SAP Solution Manager with local SLD and i want to use this system as Central SLD for my System Landscape. Later on i have installed other SAP Products like ECC,BI,PI etc.
    Some of the systems i registered with previously defined SLD in Solution Manager, but some system i forgot to register with SLD during installation.
    I am not sure or aware what is the difference between SLD configuration during installation and after installation.
    If i have Register the System during installation will it register automatically with SLD or we have to do manually.
    If i have not register system during installation and later on i want to register particular system with SLD what is procedure for that.
    Can some one share knowledge on What is Technical Systems and Business System in SLD Configuration, i tried to do some activity for SLD Configuration but after seeing above both terms i was confused so for time being i stopped this activity.
    Looking forward for kind response.

  • Sld started giving error after installation of additional usage type.....

    Hi Experts,
    I had a BW server with dual stack (AS ABAP + AS Java only base u2013 No BI u2013 Java server). Everything was running fine and I have checked that http://server:port/nwa, http://server:port/useradmin and http://server:port/sld was browsable although I didn't configured SLD.
    My BW developer team wanted to use BEX web reports and for the same I have installed following add on usage type as per note 883948 as I had only upto SPS9 as a default installation.

  • SLD : Delete Technical System (Third Party) but failed to recreate again ?

    Hi All,
    I got problem with PI 7.0 SP17 on the SLD site. I have created 1 technical system for example. SYSTEM1 on host1, but after i delete this technical system i can't create the new technical system with the same name and host
    The error message is :

    anybody has the workaround how to recreate technical system that have been deleted before ?
    Please advise.
    Thank You and Best Regards

  • SLD Setup - Technical System

    Hi All,
    I need to send/receive data from the third party using SOAP adapter. in our environmnet we follow the SLD setups for third party.
    Hence I would like to know what setup needs to be done in the SLD for this.
    I think I do not need to create new product and software component.
    Specifically when I am trying to create a new technical system the  its asking for the system name and host name.
    I beleive system name I can give anything . What about the host name ?
    Is it the host name of the third party system??
    Could some one explain me detail?
    Thanks

    H i
    What about the host name ?
    You can give the  IP address  or actual host name of the system  you are trying to connect. it cannot be any generic name.
    As mentioned above  for soap based system , generally we use Business Service but  yes if you can get all the details you can set up TS for non -ABAP based systems also . Whatever the details the TS wizard asks you to give , you have to get those details from your SOAP system admin .

  • SLD Datasupplier - Technical System Sychronization

    I understand that SLD 7.0 and 7.1 employ "automatic forwarding" that updates all data supplier targets with new system information.  But, is there a nightly synchronization job between the master and slave SLDs that synchronizes technical systems between master and slave? 
    In our scenario, we supplied the wrong SLD user in the slave SLD which we assume is the reason why technical system synchronization from Master to Slave did not occur.  Now, we need this information in the slave SLD but are unsure if a synch job will run nightly, daily, weekly, etc.

    Hi
    In 7.0 you can either use export/import to sync the content - if you use export line "LD" only the technical system data will be exported/imported, but you can also use export line ALL to export/import all SLD content (Content Repository, Landscape data, Namespaces and manuel entered data).
    However the "automatic forwarding" will eventually update your target with ALL systems that functions as SLD datasuppliers, but yo have to wait until all data-suppliers has run.

  • Imessages won't deliver after cell number change

    My husband and I recently changed our cell phone numbers, and now imessages won't deliver between us.  We both have iphone 4, ios5.1, and we had no issues at all until we changed numbers.  We share an apple id, so I've already deleted the id from my phone under Settings/messages/receive at so that it only shows my cell number.  But I still cannot send an imessage to him.  I can send imessages to other friends with iphones, but not his for some reason.  any ideas??

    I'm having a similar issue with my iPhone 5. A friend of mine is using his iPod to text me and using his email address and my phone was fine three hours ago (at 3:00pm central time), but now it won't send any of my iMessages... I've signed out of my Apple ID and made sure Facetime was enabled... and it won't send!

  • Error loading operating system after installation of Linux AS4

    Hi,
    I have Hardware HP DL580 G3 server attached with SAN.
    I just installed Linux AS4, installation went fine and successufly installed, upon rebooting of server it is giving following error.
    attempting from Hard Drive (C:)
    Error Loading Operating system
    Please help me out

    First: did you install the bootloader in the MBR (it's a question during the installation), so the server is able to boot linux automatically?
    "C:" is a typical MSDOS naming (and windows naming), which probably means the dos/windows bootloader is still in the MBR (master boot record)
    If not, reinstall linux and install grub (preferably) in the MBR

    I recently changed my phone number.  I programmed the phone per the directions provided and I had to manually go in and update the speed dial for #1 so it would dial my new number.  The issue is, if I receive a voicemail, I get the "Listen" link on the screen.  If I click that link, it still dials my old number.  I have looked through the owner's manual and through the online info on the site but have not found any way to fix this issue.

  • Can't Login to BW System after installation

    Hello People,
    I've just finished installing the BW system. I've been trying to login to the system, through the SAP Front-End. SQLServer was working and so does the bw-server, but every time i've tried to log-in I got a dump - as the first screen. The dump was DBIF_RSQL_INVALID_REQUEST.
    Someone asked me to check if system log is full, but it was quite empty. Does anyone have a clue of what to do? or did someone encounter that problem before?
    Desperately need help,
    Thank you,
    Yoav Ophek.

    Are you running it as a standalone system (with gui also on the same system)?
    Check the log files for the work processes on the application server. It could be due to connection issues between DB and app server.

  • Problem creating new ABAP Technical System in SLD

    I newly installed a ECC 5 IDES system (ABAP + JAVA) on my computer for ABAP and Webdynpro learning.
    I got problem when I try to create new ABAP Technical System in SLD.
    I put my steps of installation here so you know my full story.
    1. Install Central Instance (Non-unicode);
    2. Install Database Instance (Non-unicode);
    3. Install Java add-in on ABAP;
    4. Configure the HTTP connection parameters in J2EE Engine Visual Administrator
    All of the above steps are successful.
    Now my Webdynpro application need to access a Function Module, so I want to create a JCo connection in Webdynpro Content Administrator, but both application server and message server are not available, so I can't create any connection.
    I go back to SLD to register ABAP Technical System step by step below:
    1.      Choose Home ® Technical Systems.
    2.      Choose New Technical System.
    3.      Select the AS ABAP radio button.
    4.      Choose Next.
    5.      Enter system details (Installation number, host name).
    6.      Choose Next.
    7.      Enter message server and central application server details.
    8.      Choose Next.
    9.      Choose Next.
    10.    Add New Client 800, leave logical name blank, click Add.
    11.    Choose Next.
    12.    Here the system says 'No product available', the whole effort make no sense.
    I tried every possible settings, but at step 12 it keeps telling me 'No product available'.
    This is the problem I want to fix.
    Can anyone help me?
    Thanks a lot in advance.

    hi,

  • Archlinux fails to find lvm volumes after installation

    Hi,
    yesterday i installed archlinux on a logical volume, root and boot are both on this volume (/dev/mapper/volg-arch).
    the filesystem is ext3. the setup recognized the volume group and activated all volumes, so the installation was no problem, but when i try to start the system after installation, no volume group can be found.
    lvm2 was enabled during installation using USELVM="yes" in rc.conf and HOOKS="base udev autodetect pata scsi sata keymap lvm2 filesystems" in mkinitcpio.conf.
    i use grub2 to boot the system with the following entry
    menuentry "Arch" {
    linux (volg-arch)/boot/vmlinuz26 root=/dev/mapper/volg-arch
    initrd (volg-arch)/boot/kernel26.img
    it boots, however it cannot find any volume groups and because of that cannot load the root-filesystem.
    my other linux-system works great, which is installed on lvm2 and using grub2, too.
    did i miss a configuration?

    yes, grub2 supports it., which is really great.
    mkinitcpio was run after modifying mkinitcpio.conf automatically by the setup.
    its really odd that it works during the setup but not later.
    :: Running Hook [lvm2]
    Scanning logical volumes...
    Reading all physical volumes. This may take a while...
    No volume groups found.
    Activating logical volumes...
    No volume groups found
    :: Running Hook [filesystems]
    then it fails with errors (because of course no root-device could be found) and the ramfs-shell is started.
    i think lvm-support is enabled,
    because it is scanning for volumes.
    edit:
    just tried to boot with the following entry
    menuentry "ArchInstall" {
    linux (volg-arch-install)/isolinux/vmlinuz root=/dev/mapper/volg-arch
    initrd (volg-arch-install)/isolinux/initrd.img
    this is the volume where i copied the install-cd to (i have no cd-drive and did a hdd-install) and installed the system from.
    IT WORKS! but of course it takes too long to load this setup-initrd for using the system.
    so my initrd, generated by the setup, is wrong :-/
    any hints?
