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