Data Aging (New and Changed)

This document provides you with an overview of the new additions and changes to Data Aging in SAP NetWeaver 7.4 SP09.

Undoing Aging Run

An Undoing Aging Run corresponds with the execution of a job for report RDAAG_UNDO_RUN. You can undo only one aging run at a time for a data aging object. If an undoing aging run is already active for a data aging object and you want to start an additional run, the last run to be started for the same object is not executed.

For more information on undoing aging run, see Overview of Undoing Aging Runs.

Parallelization for Aging Runs

You use the transaction DAGRUN in the data aging framework to execute the data aging runs. This moves the data from hot partition to the cold partition in the database tables. However, since there can be large amounts of data in the different application tables, the aging run can take a long time. Parallel processing enables the processing of the data that is to be aged simultaneously in different work processes in parallel so that the aging is completed faster.

For more information on parallelization, see Parallelization for Aging Runs.
