In addition to the above protection, catalogue entries may only be deleted by users whose account matches that of the catalogue entry. However, as shown in the following example, accounts are often not common across different systems.
FM> ls -o Directory: //CERN/CNDIV/TAPES Generic filename: XTRACE91 Created by: JAMIE ACCT: JDS$CT on node: CERNVM by job: JAMIE Generic filename: XTRACE92 Created by: jamie ACCT: JDSCT on node: zfatal by job: jamie-15
To cater for this situation, account aliasing is possible. An alias file, FATMEN.ACCOUNTS, consists of 2 fields.
Note that this scheme is not designed for large numbers of users with different accounts on each machine. It is intended for use by a small number of production managers.
Example of an account alias file
EMC$XV=CCA$XV,PRO$XV CCA$XV=EMC$XV,PRO$XV PRO$XV=CCA$XV,EMC$XV
