1) Archive logging and archiving old data records are two radically different concepts. Archive logging is something the database does in ARCHIVELOG mode where an archiver process copies the online redo logs to separate files (archive logs) that are used for backup and recovery purposes. Normally, archive logs are retained just long enough to be useful in recovering the last N backups that have been taken, where N depends on the organization, the criticality of the database, the backup strategy, etc.
2) For archiving old data records, the approach is going to be driven based on the organization's particular requirements and the type of data we're talking about. Among the options
- An ETL process that moves data from an OLTP system to a data warehouse of some description for historical reporting.
- Writing old records to flat files that can be compressed and stored on cheap media (i.e. DVDs) and writing loader applications that can restore the old data to the database.
- Using partitioning and ILM (Information Lifecycle Management) to do things like moving older partitions of a table to less and less expensive media over time, compressing older partitions, dropping the oldest partitions, etc.
