How to manage archive logs?

Check status of archivelog mode:
SQL> archive log list;

Open if it is closed:
Link

SQL> SHOW PARAMETER DB_RECOVERY_FILE_DEST
-> REMOVE *.DB_RECOVERY_FILE_DEST from pfile if you desire different path

SQL> select * from V$ARCHIVE_DEST;

Define default log archive destination:
*.log_archive_dest='C:\oraclexe\app\oracle\oradata\XE\LOG_ARCH\'

Define new paths: 
*.log_archive_dest_1='LOCATION=C:\oraclexe\app\oracle\oradata\XE\LOG_ARCH_1\'
*.log_archive_dest_2='LOCATION=C:\oraclexe\app\oracle\oradata\XE\LOG_ARCH_2\'

Define duplex destination if needs
*.log_archive_duplex_dest='LOCATION=C:\oraclexe\app\oracle\oradata\XE\LOG_ARCH_DUPLEX\'

Differences between regular dest and duplex dest:
LOG_ARCHIVE_DEST calls as primary archive destination,
LOG_ARCHIVE_DUPLEX_DEST calls as secondary archive destination
The important point is that these are using only on local machine

-> On the other hand, LOG_ARCHIVE_DEST_n may use in remote and local as well.

Test the path:
SQL> alter system switch logfile;
Check archive log file in local path like "C:\oraclexe\app\oracle\oradata\XE\LOG_ARCH\"
