    Abstract

    V5R4 of IBM i5/OS provides a new choice for applications that need to enhance their transactions. It allows both batch jobs that employ commitment control and interactive transactions to jump on the super highway and capitalize on the performance benefits that are associated with journal caching. In the past, such caching benefits only applied to applications that refrained from employing commitment control. That restriction can now be lifted if you choose to employ the “soft” commit option. In some environments, the resulting performance boosts can be impressive.
