How to measure sparse file disk utilization

edited Feb 13, 2015 10:04AM in Database Administration (MOSC) 7 commentsAnswered

Hello,

I'm currently supporting an environment running a set of Oracle 11.2.0.3 database instances on Solaris 10. I recently created locally managed tempfiles. Since the tempfiles are considered sparse files, the disk utilization commands such as 'df -h' or 'zfs list' shows more space available than what truly is. So my question is: Does anyone know of a way to accurately sum up the amount of disk space consumed on a given filesystem, taking into account that some of the files are sparse?  Likewise, if I find something, I'll update this thread.

Regards,

Arun
