-n|-number 

Input syntax: -n <number of logs>|<number of volumes>

Default value: 10,000

The default value is 10,000. The program processes practically all the existing offline redo log files (or volumes for volume initialization). In other words, the files in the init<DBSID>.sap parameter volume_archive or those defined with the option -v.

You can also use the option -c to enable BRARCHIVE to perform unattended archiving of the offline redo log files.
