Parameter
es/blockdisclaimsize_KB Short text
Memory release threshold within an EM block
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/blockdisclaimsize_KB specifies the size of the upper part of an EMblock, which is also released for the operating system when released. Itcombines the benefit of smaller EM blocks (em/blocksize_KB) with regardto the main memory requirement, with the benefit of larger EM blockswith regard to performance.
