Merge analysis executes the condition analysis result accumulation facility multiple times (over multiple days), accumulating and merging the condition analysis results. For example, it is effective to execute the facility over multiple days during off-peak hours when there are comparatively fewer online jobs.
To execute merge analysis, you specify in the -n option the number of times the facility is to be executed.
Figure 15-14 provides an overview of merge analysis. This figure assumes that a single RDAREA (10 segments) is to be analyzed.
