All you need to know about the SAP BusinessObjects ONE Uninstaller

“Are you BI Administrator managing the BI system undergone multiple updates having large history of minor release(s) or Service Pack(s) and/or Patch(es) and thinking how to get rid of these obsolete intermediate versions of the BI packages?”

“And having challenges manage the ever growing footprint (size on hard disk) of the BI deployment and observing update installations take longer time for the initial screen to launch?”

Then this blog is for you and you need to consider the “SAP BusinessObjects ONE Uninstaller” tool to overcome the above mentioned challenges.

 

Wondering what is this tool and how to use this, let’s see what it is.

 

SAP BusinessObjects ONE Uninstaller is an interactive lightweight command line tool, written in java as an executable jar. Using this tool, you can optimize the footprint of BI packages installed in your BI system. This tool enables the removal of redundant/obsolete intermediate versions like Service Pack(s) and Patch(es) without following traditional uninstallation process.

 

So what are the Benefits of using this tool?

  1. Tool will free up the hard disk space drastically by removing the obsolete BI Package’s SP(s) and/or Patch(es).
  2. Future update installation launching will take comparatively less time, as the number of versions to be calculated will become less.
  3. Simple and elegant way to get rid of intermediate versions of BI Packages, where in which you do not need to uninstall and reinstall the latest version.
  4. Multiple intermediate versions of different packages of BI Suite in a BI System can be uninstalled in ONE go.
  5. Tool does not require any downtime of the BI system servers or services and applications.

 

Supported Scenarios and platforms:

  1. This tool can run on any BI 4.x system.
  2. Supported on all OS platforms, where the BI suite of packages is supported.
  3. This tool will consider BI platform add-ons SAP Lumira Server, SAP Analysis for Microsoft Office, SAP Data Services, SAP Information Steward and Explorer.
  4. This tool can also run on the system where only BI Suite Client tools packages like SAP BusinessObjects BI platform Client Tools and SAP Crystal Reports are installed.
  5. Tool can be executed with the “SAP JVM” which comes with the BI Package’s installation. You can also run the tool with Oracle Java 7 or 8.

 

Important Note(s):

  1. This tool should not be run when any Installation operation is going on, including Fresh / Update / Modify / Repair / Uninstallation of any BI Suite of products or packages in the system either through interactive mode or silent. This is not a supported scenario.
  2. This tool should be run in all nodes/machines of the Cluster setup to be in compliance with the recommended best practice to keep the BI Packages Install History same or similar in all nodes of the Cluster.
  3. Before executing this tool to clear intermediate versions in any BI Landscape, as a precautionary step, it is recommended to take the Backup of BI Landscape includes full system backup (in case of Virtual Machines, a snapshot) along with CMS DB and FileStore (FRS) and any other files, configurations and components which you take as a backup in usual update installation scenario.
  4. And to clarify, this tool will work only on the Installed binaries (footprint) on harddisk, and does not alter or change or remove or add in CMS DB and any other system repositories.

 

How to get the ONE Uninstaller tool:

  1. Download the attached archive from Note 2846512 and copy it to BI machine where the obsolete intermediate versions need to be uninstalled.
  2. Once you extract the contents of the archive, you can find the main executable of the tool “jar” along the “lib” folder and the help guide “SAP_BusinessObjects_ONE_Uninstaller_Guide.pdf”.

 

Steps to execute:

  1. Need to keep the “lib” folder always in the same directory where the “jar” exists for the successful execution of the tool.
  2. And, you need to ensure write permissions for the user executing the tool on the parent folder the jar file as the tool will create the logs folder with “OneUninstallerLogs” as its name, at the same level as the jar file exists.
  3. Command to execute to the tool java -jar OneUninstaller.jar <BI_Install_Dir>

Note: <BI_Install_Dir> is the path of the installation directory where in which the BI suite of package(s) installed.

For Example – Using the bundled “SAP JVM” :-

Windows:<BI_Install_Dir>\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win64_x64\sapjvm\bin\java” -jar <BI_Install_Dir>\SAP BusinessObjects”

Linux: <BI_Install_Dir>/sap_bobj/enterprise_xi40/linux_x64/sapjvm/bin/java -jar OneUninstaller.jar <BI_Install_Dir>

Solaris: <BI_Install_Dir>/sap_bobj/enterprise_xi40/solaris_sparcv9/sapjvm/bin/java -jar OneUninstaller.jar <BI_Install_Dir>

AIX: <BI_Install_Dir>/sap_bobj/enterprise_xi40/aix_rs6000_64/sapjvm/bin/java -jar OneUninstaller.jar <BI_Install_Dir>

 

Smart features of this tool are:

  • This tool will calculate the obsolete versions for deletion keeping in mind the overall products including BI platform, Clients and Add-ons.
  • And it first suggests the list of obsolete versions which can be safely removed, and asks the user to select any particular version(s) or all of that list.
  • This tool will only work on the InstallCahce folder under InstallData folder to clear the cache related to obsolete versions, and will not alter anything else in the installation directory.
  • In addition to the above point, this tool ensures to keep cache of the base version for future Modify operations, and also it keeps the latest version, again for the same Modify as well as Repair operations.
  • This means this tool in any circumstances will not remove both “base version” and “lastest version(s)” of any product.
  • And the beauty of this tool, it avoids the pain of traditional Un installation as it requires to follow last in first out(LIFO) order, this tool allows to remove obsolete intermediate versions.
  • Once the selection is made out of the suggested versions of obsolete SP(s)/Patch(es), tool performs the uninstallation for different BI packages installed in a BI system, related to those selected versions for uninstallation and removes them in one iteration.
  • And this tool can be executed during the production time it self, as it does not require to bring down any BI servers/services, as it only works on the InstallCache and the manifest file under the InstallData folder.
  • And one more important point, this tool will take comparatively very less time, when compared with traditional uninstallation, moreover traditional uninstallation requires the down time where this tool does not.
  • Coming to logging functionality –
    • It records all the actions what it is performing in the log file simultaneously as the execution goes on.
    • And maintains the log file separately for each iteration/launch of the tool with a separate log file named OneUninstaller.log under a timestamp folder under the OneUninstallerLogs folder
    • And also as a precautionary step, this tool along with writing log file, takes the backs up of Install Manifest db file from the InstallData folder to the corresponding log folder for that iteration.
  • This tool will also ensure to remove the corresponding entries from the Add/Remove Programs list in Windows and from the list of Installed Products in Unix.

 

Important Points to consider and remember:

  • Any action performed by this tool is irrevocable that means the obsolete intermediate versions got removed cannot be brought back to the system.
  • This tool is not for uninstalling the latest version / recent version, for that you need to perform the regular uninstallation.

Let us see some use cases:

 

Use Case 1 – Simple Standalone BI platform deployment with only one intermediate version.

BI%20platform%20stand%20alone%20installation%20with%20only%20one%20Intermediate%20version

BI platform stand alone installation with only one Intermediate version

In this scenario, as we can see, BI system contains only BI platform server installation with base installation starting at BI 4.2 SP3 and after that two updates to it. Hence the intermediate version is only one i.e. BI 4.2 SP04.

If in case if you decided to uninstall that intermediate version, then with the traditional uninstallation process you need to follow the Last In First Out order, hence first you need uninstall the latest update applied and then uninstall BI 4.2 SP04 update (intermediate version) and after that reinstall the previously uninstalled latest update.

That means total three operations you need to perform just to get rid of one intermediate version. And not only that it requires to bring the system down hence during these operations system will not be available, so, entire downtime.

Having said that you cannot simply uninstall the intermediate version as it is not the recommended way of uninstallation.

But if you use this ONE Uninstaller tool, then definitely it is safe to uninstall the intermediate version without following the above mentioned traditional process. And also with no downtime. And with this tool it finishes the uninstallation approximately ~5 mins., no way comparison to the normal uninstallation.

 

Use Case 2 – Standalone BI deployment with multiple products and add-on.

When BI Administrator planning for the next update there is a blocker for the same due to insufficient disk space and observed that update installer took longer time to launch.

Then BI Administrator executes the “SAP BusinessObjects ONE Uninstaller” tool and successfully resolves the blocker and also observes that after the successful uninstallation of obsolete intermediate versions update installer took less time to launch in comparison.

Disk%20Space%20Check%20prerequisite%20failed%20due%20to%20insufficient%20disk%20space

Disk Space Check prerequisite failed due to insufficient disk space

BI%20Suite%20of%20packages%20installed%20in%20the%20system%20and%20the%20obsolete%20versions%20suggested.

BI Suite of packages installed in the system and the obsolete versions suggested.

       After successfully uninstalling the obsolete intermediate versions Disk Space Check passed.

 

In this scenario, tool uninstalled the 11 versions of different products in about ~20 min. time in a single iteration.

 

Another%20Example%20BI%20system%20similar%20to%20what%20is%20explained%20in%20Use%20case%202.

Another Example BI system similar to what is explained in Use case 2.

 

Use Case 3 – No Intermediate versions available for uninstallation

Wondering%20why%20Intermediate%20version%20not%20being%20suggested%20for%20uninstallation

Wondering why Intermediate version not being suggested for uninstallation

In the above scenario though the intermediate version BI 4.2 SP8 Patch 2 update exists for BI platform and BI platform Client Tools packages but still it has not been suggested for uninstallation, wondering why, because if you observe the list, there is another product Explorer exists but that product’s latest version is not at the same level as that of BI platform and Client Tools package, and the latest version for Explorer is BI 4.2 SP08 Patch 2, hence the tool will not consider that version for uninstallation to safeguard the common binaries between BI platform and Explorer packages being deleted.

This way this tool is very cautious about calculating the intermediate versions for uninstallation.

 

Hope this helps. Happy cleaning and welcome to the optimized BI system with respect to disk space footprint.

  • I got the error: SAP Note/KBA 2846512 is being created.

    The SAP Note/KBA you were trying to reach is currently being created and has not yet been released.

    When will the note be released?

  • Thanks Venkat. This will be a great tool for BI administrators looking to free up disc space on existing systems and cleaner/faster installs.

    fyi. the note is released now.

  • Hi,

    I’m trying to use this but it’s not working.  Here is the content of the log:

    On my Server I have BOBJ stuff from BI 4.2 SP07, SP08 and now 4.3.  I’m hoping to delete the BI 4.2 stuff.

    The manifest file is 9.4MB!

    Thanks.

    • Hi Patrick Perrier,

      Can you share the list of BI Suite of product versions installed by sharing the screenshot from Add/Remove programs and also share the contents of Inventory.txt from InstallData folder under installation directory. So that we can review and suggest why the tool suggesting as nothing to remove.

      Regards, Venkat.

        • Hi Patrick,

           

          After analyzing the shared Install history of BI Suite of Products and other SAP packages,

          We need to consider the packages mentioned only in the inventory.txt as these are packages which are under the same installation directory where the BI platform is installed, as these are either the packages which gets released along with BI platform as part of BI Suite release or BI platform add-ons.

          Note: The other packages listed in the add/remove programs and which are not there in the inventory.txt will not come into the scope of the tool as they are not installed in the same installation directory as by design, because of the following reasons, either they are not related to BI Suite of packages or they are not using the same Install framework or they are by design gets installed in different directory as in the case Lumira Discovery, though it uses the same Install framework as BI platform.

          So, coming to the packages captured in inventory.txt, and analyse the list, we can represent the same in the tabular format for easy inference :

          If we leave aside the two non BI Suite release add-ons (i.e. “Lumira Server” and “Analysis Office for BI Platform”, which will have different release cycles) as the versions for these are single and does not have any other history, so there is no case of obsolete intermediate versions for these two packages.

          And consider the remaining packages which are part of BI Suite releases in the above table it is evident that there is no common intermediate version, if we observe, BI 4.2 SP08 will look like as an intermediate version, but if we see it is not a common intermediate version for all the BI Suite of packages. As Explorer package’s latest version is BI 4.2 SP08 and also the only version for the Dashboards (Client package) is also BI 4.2 SP08, hence tool will not consider that version as obsolete version, because there will be some common binaries between these packages which are must required for these two packages to function properly.

          So to do a proper cleanup of intermediate (obsolete) versions in this machine, you can perform the following steps:

          1. Manually un-install Dashboards client
          2. Run the ExplorerRemover tool to cleanup the Explorer packages please refer https://launchpad.support.sap.com/#/notes/2930751
          3. And finally run the ONE Uninstaller

          Note: Step 1 and Step 2 need to be performed only after reviewing the relevant Notes related to those Products mentioned in the Note https://launchpad.support.sap.com/#/notes/2801797

          Let me know, if you still face any problem, ideally after performing Step 1 & 2, tool should suggest BI 4.2 SP08 as removable version.

          If in case if it is still not suggesting means, we need to analyse either because of Lumira Server add-on or AOffice add-on dependencies with BI platform can be blocking that version to delete. But I believe it should not be the case, Let us know the result.

           

          Hope this clarifies.

          Regards, Venkat.

          • Hi Patrick,

             

            As suggested in my previous reply, you did not removed the Explorer product, please refer my previous reply, in which I have mentioned three steps, in that you followed only step 1, but you missed step 2.

            Please perform the prescribed steps in the order as mentioned in my previous reply.

            And I have explained why you we need to perform step 2 (i.e. removal of Explorer product) please refer my previous reply fully again.

             

            And after performing the steps as prescribed, please let me know here.

             

            Regards, Venkat.

          • Right I did miss that step… Just one line stating this would have been enough.

            I have manually uninstalled Explorer 4.2 SP07 and SP08.  Then launched the One Uninstaller.

            This is not a solution I will be testing any longer or using in a real life.  Seems like a black box doing half of what you would expect.  Leaving things behind.  Who knows what else is going on.

            I don’t see why it can’t delete Explorer and Dashboard as it’s pointless if you have BI 4.3

            Final comment, if you uninstall like in my case 4.2 SP07, 4.2 SP08 and leave 4.3 you don’t have the Modify option anymore for 4.3.

            I discussed this in my BI 4.3 Upgrade Blog, in my opinion a side by side upgrade seems to be the only real thing to do and avoid risks steps like these.

          • Hi Patrick,

            It seems there may be some misunderstanding as to what this tool does. It will remove only obsolete packages and patches. This is to help prevent a long standing issue whereby customers installs take longer than they should, and a lot of disk space is used, because they have a large patch history.

            It will not remove base versions (SP07 in your case) or current versions (4.3) because as you noticed, base versions are required for modify / repair actions. This is expected behaviour.

            Inventory.txt version removal by the tool is an enhancement request that’s on the list. Perhaps removal of Explorer and Dashboards after upgrade to 4.3 is also something we could have as a planned enhancement.

            I’m slightly concerned by this comment:
            Final comment, if you uninstall like in my case 4.2 SP07, 4.2 SP08 and leave 4.3 you don’t have the Modify option anymore for 4.3.

            I assume 4.2 SP07 was not removed by the tool (as expected) and instead you were able to uninstall 4.2 SP07 manually? Thereby losing the ability to run a modify or repair (since 4.2 SP07 was the base version). If this is the case please confirm. Manual uninstallation of base versions should be something we prevent, and that’s something we might need to look in to if you were able to do this.

            Thank you,
            Graham

    • Thanks a lot Denis for bringing this point. I have included this in the Important Notes section in the blog and will do the same in the Note as well.

       

      Regards, Venkat.

  • I’ve tried to run this on our DEV system and got the following error:

    We currently have 4.3 installed, is it not compatible with 4.3 yet?

    • Hello Ruan,

      There is a known bug in the current version of the OneUninstaller.

      Development are actively working on it and it’s tracked in the below SAP Note:
      2951139 – ONE Uninstaller fails with NumberFormatException when a hotfix is present

      The fixed versions will be released there once available.

      Thank you,
