This space provides the same content as before, but the organization of the home page has changed. The content is now organized based on logical branches instead of legacy book titles. We hope that the new structure will help you quickly find the content that you need.

Product functions

The following figure illustrates the two basic functions of R+/CHANGE ACCUM:

  • Creating change accumulation groups

  • Generating change accumulation files

You create change accumulation groups through the online interface. Change accumulation files are generated through batch processing.

When you define a change accumulation group, you specify a set of target objects. A target object is a table space, partition, or Db2 data set. A change accumulation group can include certain combinations of table spaces, partitions, and data sets.

When you run an R+/CHANGE ACCUM job, data from the log records for the target objects and, optionally, their indexes are extracted and stored in a change accumulation file.

Change accumulation group definitions and data about change accumulation files are stored in the R+/CHANGE ACCUM repository.
