For long index analyses or cases where the workload has many SQL requests that must be analyzed, you should always specify a checkpoint using the CHECKPOINT option.
The checkpoint trigger value indicates the frequency with which a checkpoint is logged in the AnalysisLog table. A checkpoint is taken after every n request occurrences, where n is the checkpoint trigger value, and the interim index analysis information is logged.
Note that you can specify both the CHECKPOINT and the TIME LIMIT options for an INITIATE INDEX ANALYSIS request.
For information about how to restart a checkpointed index analysis, see RESTART INDEX ANALYSIS.
