Parameter
es/disclaim_threshold_MB

Short text
Release EM memory above threshold value for the OS.
Background
You can use this group of instance profile parameters (see below) tocontrol the amount of memory released for the operating system dependingon the fill level of the extended memory and thereby minimize theassociated disadvantages. Memory above an adjustable threshold in theextended memory is always released for the operating system. As soon asthis threshold is exceeded, memory below this threshold can also bereleased for the operating system for a specified time period. When EMblocks are released, a definable size of the upper section of the EMblock can also be released for the operating system.
es/disclaim_threshold_MB defines the threshold value in MB. If memoryblocks are requested above this threshold, for instance when there is ahigh load, these blocks are released for the operating system at thesame time as they are released for the SAP system.
