The individual Components The Archiving Monitor
3.1.2 Logging
While the archiving monitor is active, the occupancy level of the archive direc-
tory and other important events are logged at regular intervals
(AMON_INTERVALL) in the protocol file
${DBO_CONFIG_DIRECTORY}/prot/redologs/amon.prot.
Protocol file
There are four generations of the protocol file. The current protocol file is
appended to the file amon<sid>.old with each restart. If this file exceeds a size
of 5 Mbytes, it is renamed from amon<sid>.002 to amon<sid>.003 and
amon<sid>.old is changed to amon<sid>.002.
Archiving log file
All of the files backed up by the archiving monitor are logged in the /nsr/ora-
cle/<ORACLE_SID>/prot/save_logfiles file. There are four generations of this file.
With each restart, the file is appended to save_logfiles.old, if it does not exceed
1 Mbyte as a result. Were this size to be exceeded, save_logfiles.old is renamed
save_logfiles.002 and the current file is renamed save_logfiles.old.
The following is a representative sample from the log file:
