    OK very good.

    In addition to update the documentation, hcl should as well adjust the Notes Client Installer for Citrix Installations.


    At the moment Notes Client will be installed using command line using CITRIX=1 statement.

    After Installation has been completed, you need to perform generall tunings for the client before activating Citrix Server for Clients, including but not limited to Share JVM for all users instead of maintainige a Single JVM per user. (Memory Consumption)


    In case CITRIX=1 is deployes durint installation, the installer should automatically perform the requiere adjustments for Tuning Notes Client under Citrix.

    • stop and disable unused Services

      • LNSUSvc, HCL Client Update Services, etc.

    • Adjust or disable Data Execution Prevention.

    • ShareClasses Improvments : to Share JVM between all users instead of a singleJVM
      ...\HCL\Notes\framework\rcp\deploy\jvm.properties file

      • create a ShareClasses folder under ProgramData\hcl\notes\data with NTFS Permission everyone rw access

      • Add/modify: vmarg.Xnolineumbers=-Xnolineumbers

      • modify: vmarg.Xmx from "-Xmx256m" to "-Xmx512m" (for notes v11 max 1024m)

      • modify: vmarg:Xms from "-Xms64m" to "-Xms256m"

      • change: vmarg.Xmca=-Xmca512k

      • Remove: "SingleJVM" in vmarg.Dshare

      • modify: jvm.shareclasses.loc=C:/ProgramData/HCL/Notes/Data/ShareClasses (!! use / statt \ !!)

    and so on.

    To make long story short - Installing Notes Client under Citrix should by default be tuned for Multiple Client usage!
