An alarm appears, indicating a long average time for data collection against an Oracle datafile.
This could happen for the following collections:
DBO - Datafile Avg IO Time
DBO - Datafile Avg Write Time
DBO - Datafile Avg Read Time
There is an unpublished Oracle bug (bug ID 8252192) that can cause the issue. The bug causes the time to be reported in the wrong units in v$filestat.
Please contact Oracle support to get this fixed.
