The DB version is 11.2.0.3. The real need is to find out LGWR switches on 
hourly basis. I can pull this information from the archive log view as well but 
I was curious to know if there was also a DB statistic available that can 
provide similar information.

Depends on what you're really trying to find and which version you're on.

"background checkpoints started" might be what you need.

Hi,
Is there a database statistic available that can tell how many times LGWR 
switched redo log files?

Thanks,
Amir
