    Abstract

    Remote journaling can be used in a variety of ways, from simply routing journal receivers to a distant electronic vault to helping achieve high availability.

    When defining and creating a remote journal, you face an important choice regarding which type of remote journal should be selected. The remote journal option names themselves (*TYPE1 and *TYPE2) are part of the problem, for they are not too descriptive and there has often been confusion between the two choices.

    In a nutshell, the type of remote journal that you choose impacts the subsequent interchangeability of resulting journal receivers. This technote attempts to make that distinction clearer and provides examples of various uses for remote journaling which in turn helps provide some guidelines and rules of thumb for deciding which remote journal type to choose.

    If you choose wisely you’ll have versatility matched to your particular needs. If you choose haphazardly you might end up disappointed and wondering why you feel limited in achieving the versatility you yearn for.
