Table 1 shows a series of LFAREA requests on a z/OS® system with 64 GB of online real storage at IPL. The 1 MB pages are requested with target and minimum percentages of 40% and 20%, respectively, while the 2 GB pages are requested as a target numerical value that is increased with each request. This illustrates how the 1 MB pages are reduced toward the minimum to satisfy the requested target number of 2 GB pages. Table 1 also shows that as the number of 2 GB pages reaches 19, the required reduction in 1 MB pages would be below the requested minimum. In this case, the system prompts to re-specify LFAREA. Also shown is a case where the requested number of 2 GB pages is 25, which by itself exceeds the 80% system limit and results in a prompt to re-specify LFAREA.
