Nonstop Database, HiRDB Version 9 Installation and Design Guide
A superuser can set up a group of HiRDB users in the OS of each server machine. The name of the group must be eight or fewer alphanumeric characters starting with a letter.
By setting a HiRDB group, users other than the group can be blocked from creating files under the HRDB file system area and HiRDB directory. This enhances security.
