Hi Azeeker,

Yes, if shutting down just before the periodic checkpoint you could loose a few percentage points on resume. It depends on the project and also how many segments are packed in a job.

Visit the Start Here forum Checkpoint Saving FAQ to learn how to identify the checkpoints in the graphics or through activating the checkpoint message logging.

At top of screen, from drop down list Quick Go >> Start Here.....

Azeeker,
In the Checkpoint FAQ do not miss the paragraph about the "Write to disk interval (WTDI)" if you run projects other than DDDT and Rice. For those two, they checkpoint frequently enough for your actual checkpoint to be taken soon after the WTDI is elapsed. But for other projects with longer checkpointing intervals, if you set the WTDI too high it may happen that your WU wants to checkpoint just before the WTDI allows it and in that case this checkpoint opportunity is simply lost, leading to an actual checkpointing interval twice longer than it could be.

If you do not run highly disk intensive applications in your normal activity my personal recommendation would be to keep the WTDI at its default 60-second value.

Cheers. Jean.
