Log file rotation is the creation of new log files, when the file exceeds a specified threshold or date.
Take the MaximumFileSizeKb setting for the component log configuration file for the Oracle BI Scheduler as an example. Whenever a log file exceeds the size that is specified by this setting, then the existing Scheduler log file is renamed, and a new log file is created.
· nqscheduler.log — The latest log file.
· nqscheduler-<n>.log — The renamed previous log file.
where <n> = date and timestamp,
for example nqscheduler-20100909-2135.log
where <n> = date and timestamp,
for example nqscheduler-20100909-2135.log
Additionally, a log file date that is older than the MaximumLogAgeDay setting is deleted.
