The service machine should have the name FM throng, e.g
throng
FMALEPH, FMCHARM2, FMCPLEAR, FMDELPHI, etc.
The account created requires a 191 disk of sufficient size
to maintain the expected file catalogue information. Some 800 bytes
are required per file catalogue entry, thus for a catalogue containing
15000 files, about 20 cylinders are required. A 193 disk is required for
maintaining journal information.
This disk should be at least 5 cylinders.
| 191 | Disk for FATMEN RZ file, log file and |PROFILE EXEC|. The profile exec contains only one line - |'EXEC FATPROF'| 20 cylinders is normally sufficient for an initial allocation for this disk. |
| 192 | Link to the disk containing the server code and EXECs. At CERN, these are kept on the 191 disk of userid FATMEN. |
| 193 | Disk for keeping journal files. About 5 cylinders are normally required. These files are created automatically by the server following each update and are named |FATyyjjj FZhhmmss|, e.g. |FAT90001 FZ120000| for a file created at 12:00:00 on January 1st, 1990. |
Table: Mini-disks required for FATMEN service machines
On CERNVM, the FATMEN service machines are monitored and controlled by the FATONE machine. Any new service machines must be registered by running the FATMEN exec on the 191 disk of this machine, as shown below.
