By default, all file accesses that use the routine FMOPEN or the shell FIND or MAKE commands result in a logging record being sent to the servers. This record contains information which includes how the file was accessed, the time taken to access the file and updates the usage count and last access date and time.
Such updates can be controlled by a file named FATMEN.UPDATES which has the same format as the FATMEN.ACL file. If such a file exists, then the logging information will only be sent if there is an appropriate line in this file.
Example of an update control file
! ! Log monitoring information only for production users ! DELPROD * //CERN/DELPHI ! ! but also for users accessing their private files ! <user> * //CERN/DELPHI/USERS/<user>
