Take a look at these two settings:

DeleteStudyOnlyIfCopyOnMedia

DeleteStudyOnlyIfCopyArchived

Carefully read the descriptions, I believe you are missing the DeleteStudyOnlyIfCopyOnMedia one

What about the value of ScheduleStudiesForDeletionInterval?

Also check DeleteStudyOnlyIfCopyOnFileSystemOfFileSystemGroup, if you are really sure that there is a copy on NEARLINE you could try to set that to NONE just to test it.

Try to check the contents of the study_on_fs table, check if you have entries for the ONLINE file system with access_time that matches your criteria.

Ok. thanks for the update. I will check that. And I try to delete the study from the ONLINE storage using the method scheduleStudyForDeletion() function, it shows as deleting in the server log. but, none of the file are deleted from the ONLINE file system or from the database entry. after that I try to invoke another study. but returns 0 as the size scheduled for deletion. can i overcome this?

I checked the study_on_fs table, the last access time matches the criteria and mark_to_delete column has been set as true. But still the study not deleted from online storage.
