Objects you should journal

 

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 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 is it 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 is 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 does the delay in reconstructing changes have on the business?

• How does the object relate to other objects on the system? Although the data in a particular object might not change often, that object's data might be critical to other more dynamic objects on the system. 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 operation.
