Parameter
es/disclaim_threshold_MB
Short text
Release EM memory above threshold value for the OS.
Parameter Description
Background
You can use this group of instance profile parameters (see below) to control the amount of memory released for the operating system depending on the fill level of the extended memory and thereby minimize the associated disadvantages. Memory above an adjustable threshold in the extended memory is always released for the operating system. As soon as this threshold is exceeded, memory below this threshold can also be released for the operating system for a specified time period. When EM blocks are released, a definable size of the upper section of the EM block can also be released for the operating system.
es/disclaim_threshold_MB defines the threshold value in MB. If memory blocks are requested above this threshold, for instance when there is a high load, these blocks are released for the operating system at the same time as they are released for the SAP system.
