Fathom Replication and after-imaging: a summary

Implementing Fathom Replication with after-imaging requires several considerations:

Understanding how Fathom Replication can be configured is important when making design and implementation decisions.
After-image processing is critical for maintaining database performance at an acceptable level and for maintaining optimum performance of Fathom Replication. The after-image implementation must be resilient and stable.
The number of after-image extents required and volume of these extents are dependent on your business decisions and the hardware that is available for after-imaging and Fathom Replication.
Business considerations must be taken into account when determining the configuration of after-image extent sizes and archiving.

Operational planning is especially important for a successful Fathom Replication implementation.
