How do I determine the amount of ASM disk used by database?
I am trying to generate a report that will show me the amount of ASM disk space allocated, used, and free for each database. Is there a view or set of views in the ASM instance I can query to determine this? I know I can go to each database and get the info from dba_segments and dba_free_space. I want to be able to generate a weekly report showing how much ASM space is used by each database and I would like to be able to get it from one source. Is that information in the ASM instance?
