The shared pool paging option controls whether the system dynamically adjusts the paging characteristics of the storage pool for optimum performance.
A shared pool paging option other than *FIXED can have an impact on data loss for nonjournaled physical files in a system failure. When you do not journal physical files, data loss from a system failure, where memory is not saved, can increase for *CALC or USRDFN paging options. You can write file changes to auxiliary storage less frequently for these options. There is a risk of data loss for nonjournaled files with the *FIXED option, but the risk can be higher for *CALC or user-defined (USRDFN) paging options. For more information about the paging option, see Automatically tune performance of the Performance topic.
