patch manager reinstallation fails - another instance detected

  • 1.  patch manager reinstallation fails - another instance detected

    Posted 01-18-2017 05:34 AM

    hi,

    i have installed the CA Patch manager on a server separate from my domain manager/scalability server.

    for some reason, i could not download patches with this patch manager, so i deinstalled the software and tried installing

    the patch manager on my domain manager. This failed with the message "another instance of patch manager  detected ...

    skipping patch manager installation" (see pic1).

    the same error pops up when i try to reinstall the patch manager software on the original separate server.

    when i open the web console on my domain manager and go to patch management,

    i see the old (false) patch manager host information "mnpatchmgr.staging.local" is still available (see pic2). unfortunately, there is no option to delete it.

    my question: can i delete the old patch manager information in order to be able to reinstall the patch manager software on the domain manager?

     

    any help would be appreciated:-)

    Hi Gregor,

    check Add/Remove programs if there is anything left from PatchManager. If so, remove it, reboot the server and try the installation again.

    You could check the following SQL table:

     

    select * from ca_application_registration

     

    See what it lists as product specific data for CA Patch Manager

    Hi Gregor,

     

    I agree with Gordon. The problem could be in table ca_application_registration

    If UPM has been uninstalled but this SQL Query returns 1 row :

     

    select * from ca_application_registration where product_code=2035

     

    Then you could execute this :

     

    delete from ca_application_registration where product_code=2035

     

    and try again the installation.

    Hi Jean-Yves,

     

    thank you for your answer - it works!

    After deleting the sql item, the defunct patch manager information is removed from the web console,

    and i was able to reinstall patch manager on my domain manager.

    May I ask how you how you came to this solution ?

     

    Cheers and again thanks to all answers!

    Hi Gregor,

     

    When UPM is installed a row in table ca_application_registration with product_code=2035 is added.

    This table is used to know which products are installed.

    When we try to install UPM, UPM installer checks this table and if it sees a row with product_code=2035 already present in the table, it displays a message like "another instance of patch manager  detected ..."

     

    Normally when UPM is uninstalled this row is deleted. But maybe a problem has occured during uninstallation and the row is database was not deleted.

     

    Thanks.

    Regards,

    Jean-Yves
