You can choose to enable the loading of application data in to the device memory as and when required by setting the LoadAppdataIntoMemoryOndemand registry key to true. This helps significantly on low memory devices:
Open the Registry Editor.
Go to HKEY_LOCAL_MACHINE\Software\Novell\ZCM.
(Conditional) If the registry key named LoadAppdataIntoMemoryOndemand already exists, ensure that its value is set to True, else create a String named LoadAppdataIntoMemoryOndemand and set its value to True.
