LOG_ARCHIVE_MAX_PROCESSES

LOG_ARCHIVE_MAX_PROCESSES specifies the number of archiver background processes (ARC0 through ARC9) Oracle initially invokes.

• If the LOG_ARCHIVE_START initialization parameter has the value true, then this value is evaluated at instance startup. Note that the LOG_ARCHIVE_START initialization parameter was deprecated as of Oracle Database 10g Release 1 (10.1).

• Otherwise, this parameter is evaluated when the archiver process is first invoked by SQL*Plus or SQL syntax.

The actual number of archiver processes in use may vary subsequently based on archive workload.
