1.查看当前归档日志目录
SQL> show parameter recovery
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /u01/app/oracle/fast_recovery_
area
db_recovery_file_dest_size big integer 4182M
recovery_parallelism integer 0
2.更改归档日志目录
SQL> alter system set db_recovery_file_dest=‘/u01/app/oracle/archivelog‘ scope=spfile; System altered.
3.更改归档日志目录大小
SQL> alter system set db_recovery_file_dest_size=4096m scope=spfile; System altered.
4.重启数据库并查看归档日志目录及大小
