The setup process automatically tunes the percentage of the db-cache-percent property for the userRoot backend based on the maximum configured Java Virtual Machine (JVM) heap size. This is only done for the userRoot backend during setup. Other backends created by the user are allocated 10%. Change the allocation if needed. When setting up the server:

  1. Install the server with the necessary memory.

    The server autotunes the size of the cache.

  2. Set the autotuned cache size to the limit for the combined cache sizes of all of the backends.
  3. Divide the server cache based on the expected size of the data in each backend.
