There are certain questions to consider when deciding whether to
journal an integrated file system object.
You need to consider the following questions to determine which objects
you need to journal:
- How much does the object change? An object with a high volume of changes
between save operations is a good candidate for journaling.
- How difficult would it be to reconstruct the changes made to an object?
Are many changes made to the object without written records? For example,
an object used for telephone order entries would be more difficult to reconstruct
than an object used for orders that arrive in the mail on order forms.
- How critical is the information in the object? If the object had to be
restored back to the last save operation, what effect would the delay in reconstructing
changes have on the business?
- How does the object relate to other objects on the server? Although the
data in a particular object may not change often, that object's data may be
critical to other, more dynamic objects on the server. For example, many objects
depend on a customer master file. If you are reconstructing orders, the customer
master file must include new customers or changes in credit limits that have
taken place since the previous save.
