Im trying to delete a file on solaris 2.6 and I get this error message
rm: crmsa2_data01_01.dbf not removed: Permission denied

I am the owner of the file but somehow the operating system does not allow me to delete this file.

-rw-r----- 1 oracle dba 838862848 Oct 3 16:32 crmsa2_data01_01.dbf.

Has anyone got any ideas why this is occuring?
