    Use following command

    ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=2

    You should define number of ARCn processes depending on number of log files and database workload. For example, if you use 5 or more logfile groups and your database is very active you can use 2 or more Archivers.

    Although LGWR can automaticly increase number of ARCn processes. You can define initial number with LOG_ARCHIVE_MAX_PROCESSES to insure ARCn can handle workload and to avoid overhead for starting new processes dynamically.
