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

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
