delete orphan dataset

[RayLade]

Is it OK to use a unix rm statement to remove the orphan datasets in my resource disk "/cba_app/dstemp/iis_fdm/datasets/temp01" {pools ""} directories ?
I would use orchadmin rm on them, but the dataset definition files have already been deleted.

Normally for Dataset descriptor deletion, orchadmin or Dataset management utility should be used, which ensure descriptor and raw data files, both are deleted.

If the descriptor are deleted usin unix rm command without considering the raw data files, how will you find out which the orphan raw data files and which are not?
If you have the list of them, then I do not think there is any harm in doing that.

If the Descriptor file has been deleted using rm command, then you have no choice left out, other than deleting the data file using rm command. But as mentiond, you need to be carfull about the data file that do not belong to any other descripot file.
Optionally, you can try to create another dummy dataset with the same name, and check if the data file been replace. If so, you can delete the newly created dataset using orchadmin -rm command.

Thank you both for your feedback.
I know the name of the orphan datasets as their raw data filenames contain the name of the user who created them.
I shall go through my four temp directories and rm away the orphans.

thanks again for the prompt advice.

What about the control files (*.ds)? If you specify these, using either the GUI or the orchadmin command (orchadmin rm controlfile.ds), then the actual data files are automagically removed too.
