What is the naming convention used for files in the ontape backup directory?
The directories specified using the ONCONFIG parameters TAPEDEV and LTAPEDEV provide the target location for ontape level 0 backup files and logical log backup files, respectively. In order to avoid duplication and assure unique filenames, a specific naming convention is used.
The filename used for file backups is
Day= Day of week
Mon=3 letter month name (in english)
hh= 2 digit hour (24 hour format)
mm=2 digit minute
ss= 2 digit second
Year= four digit (Gregorian) calendar year
XXXXXX is a unique OS generated string
Also, temporary file names may be visible until a backup completes.
'ONTL_'+<filename> == indicates a logical log file backup in progress.
'ONTA_'+<filename> == indicates a level 0 file backup in progress.
Note: Time references are derived from the system timestamp.
