BayaiM__oracle切換歸檔模式(步驟)：
------------------oracle11g設定歸檔模式和非歸檔模式--------------------------
[[email protected] ~]#mkdir /u01/arch
[[email protected] ~]#chown -R oracle:oinstall /u01/arch
[[email protected] ~]#sqlplus / as sysdba
SQL> archive log list;
SQL> select name, log_mode from v$database;
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;
SQL> alter system set log_archive_dest_1='location=/u01/arch' scope=spfile;
SQL> shutdown immediate;
SQL> startup;
SQL> show parameter dest;
log_archive_dest_1 string location=/u01/arch
SQL> alter system switch logfile; -- 是強制日誌切換，不一定就歸檔當前的重做日誌檔案（若自動歸檔開啟，就歸檔前的重做日誌，若自動歸檔沒有開啟，就不歸檔當前重做日誌。）
SQL> /
[[email protected] arch]# pwd
/u01/arch
[[email protected] arch]# ll
-rw-r----- 1 oracle oinstall 8863744 11月 2 14:53 1_12_991067760.dbf

[[email protected] ~]$ lsnrctl

修改日誌檔案命名格式
alter system set log_archive_max_processes = 5;
alter system set log_archive_format = "archive_%t_%s_%r.log" scope=spfile;

對於小白人，無腦操作，完全按照我的步驟就好，不要問，記住不懂得不要問，只要做就好了。
