Confirming Checkpoints

Arun Sirpal shows how to log when checkpointing runs:

Via Configuration manager I enabled trace flags 3502 and 3605 – both needed to get the checkpoint information and write it to the error log.

Notice the ‘s’ in front of the spid<number>? Well that means the checkpoint was done via the automatic process; if you do a manual checkpoint it won’t see this letter.

I did not know that the “s” indicated that this was an automated process.
