If the database runs in archivelog mode, then Oracle will archive the online
redo log files whenever a log switch occurs. It is important that there is
enough free space on the dedicated disk(s) for the archive files, otherwise the
ARCHiver process can not write and a crash is inevitable.
This article determines how much free disk space is needed to support growth of
the archive files. Data from the log history is gathered for analysis. This
article is not based on actual formulas but rather on human interpretion of the
information retrieved from the log history.
