$ ls （全在软件目录下面/u01，没有在数据盘下面/oradata）
control01.ctl redo01.log redo02.log redo03.log temp01.dbf
/u01空间不够，计划迁移 redo，control，temp文件到/oradata下
/dev/oracle_lv 16.00 0.53 97% 39863 22% /u01
1.redo
思路：创建redo，drop redo
查看看redo
SQL> select INST_ID,group#,thread#,bytes/1024/1024 mb,members,status from gv$log order by 3,2
2
SQL> /
INST_ID GROUP# THREAD# MB MEMBERS STATUS
---------- ---------- ---------- ---------- ---------- ----------------
1 1 1 50 1 INACTIVE
1 2 1 50 1 INACTIVE
1 3 1 50 1 CURRENT
SQL> select member from v$logfile;
MEMBER
------------------------
/u01/app/oracle/oradata/actdb/redo03.log
/u01/app/oracle/oradata/actdb/redo02.log
/u01/app/oracle/oradata/actdb/redo01.log
ALTER DATABASE ADD LOGFILE GROUP 4 '/oradata/ACTDB/datafile/redo04.log' SIZE 500M;
alter system switch logfile;
/
/
/
alter system checkpoint;
INST_ID GROUP# THREAD# MB MEMBERS STATUS
---------- ---------- ---------- ---------- ---------- ----------------
1 1 1 50 1 INACTIVE
1 2 1 50 1 INACTIVE
1 3 1 50 1 INACTIVE
1 4 1 500 1 INACTIVE
1 5 1 500 1 INACTIVE
1 6 1 500 1 CURRENT
SQL> alter database drop logfile group 1 ;
Database altered.
SQL> alter database drop logfile group 2;
Database altered.
SQL> alter database drop logfile group 3;
Database altered.
SQL> select INST_ID,group#,thread#,bytes/1024/1024 mb,members,status from gv$log order by 3,2;
INST_ID GROUP# THREAD# MB MEMBERS STATUS
---------- ---------- ---------- ---------- ---------- ----------------
1 4 1 500 1 INACTIVE
1 5 1 500 1 INACTIVE
1 6 1 500 1 CURRENT
redo就迁过去了
2.tempfile
思路：创建tempfile，drop tempfile
SQL> select FILE_NAME,TABLESPACE_NAME from dba_temp_files;
FILE_NAME
-----------------
TABLESPACE_NAME
------------------------------
/u01/app/oracle/oradata/actdb/temp01.dbf
TEMP
给temp临时表空间添加tempfile
alter tablespace TEMP add tempfile '/oradata/ACTDB/datafile/temp01.dbf' size 32000m;
alter tablespace temp drop tempfile '/u01/app/oracle/oradata/actdb/temp01.dbf'; --需要导文件目录中rm文件
ALTER DATABASE TEMPFILE '/u01/app/oracle/oradata/actdb/temp01.dbf' DROP INCLUDING DATAFILES; --直接删除临时数据文件
FILE_NAME TABLESPACE_NAME
----------------------------------------------------- ------------------------------
/oradata/ACTDB/datafile/temp01.dbf TEMP
3.控制文件
思路：
1.create pfile
2.关闭数据库
3.cp controlfile，修改pfile中的controlfile路径，
4.拉起数据库，再create spfile
5.以spfile启动数据库
SQL> select name from v$controlfile;
NAME
---------------------
/u01/app/oracle/oradata/actdb/control01.ctl
/u01/app/oracle/fast_recovery_area/actdb/control02.ctl
create pfile='/oradata/ACTDB/datafile/pfileactdb.ora' from spfile;
#*.control_files='/u01/app/oracle/oradata/actdb/control01.ctl','/u01/app/oracle/fast_recovery_area/actdb/control02.ctl'
*.control_files='/oradata/ACTDB/datafile/control01.ctl','/oradata/ACTDB/control02.ctl'
shutdown immediate
SQL> startup pfile='/oradata/ACTDB/datafile/pfileactdb.ora';
