Oracle修改Tablespace的Name
Oracle修改TableSpace的Name ???? 在Oracle10g以前，tablespace的name是不可以随意修改的，只能drop掉之后重建，但是在10g之后，oracle加入了修改的功能，除了system和sysaux两个表空间外，其他的表空间都可以改名。今天专门来记录一下这个特性： ???? 为TableSpace改名的举例如下： ?SQL> create tablespace wxq_tbs datafile '/opt/oracle/product/10.2.0/oradata/wangxiaoqi/wxq_tbs.dbf' size 1M; ?Tablespace created.
SQL> alter tablespace wxq_tbs rename to wxq_tbs2; ?Tablespace altered.
SQL> select tablespace_name,status from dba_tablespaces; ?TABLESPACE_NAME????????????????????????????????????????????? STATUS
------------------------ ------------- SYSTEM?????????????????????????????????????????????????????? ONLINE
UNDOTBS1???????????????????????????????????????????????????? ONLINE
SYSAUX?????????????????????????????????????????????????????? ONLINE
TEMP???????????????????????????????????????????????????????? ONLINE
USERS??????????????????????????????????????????????????????? ONLINE
OWB_TBS????????????????????????????????????????????????????? ONLINE
RECOVERY_TBS???????????????????????????????????????????????? ONLINE
STREAM_TBS?????????????????????????????????????????????????? ONLINE
WXQ_TBS2???????????????????????????????????????????????????? ONLINE
SQL> select tablespace_name,file_name,status from dba_data_files; ?TABLESPACE_N FILE_NAME?????????????????????????????????????????????????????? ? STATUS

WXQ_TBS2???? /opt/oracle/product/10.2.0/oradata/wangxiaoqi/wxq_tbs.dbf????????? AVAILABLE ????? 此时，datafile的名字没有改过来，与tablespace不一致，所以需要再改一下，这个过程相对来说比较复杂，要以下面的顺序来修改： ???? 1、把相应的tablespace改成read only; ??? 2、把需要修改的datafile置为offline; ??? 3、在操作系统中改名 ??? 4、alter database rename file .. to ..; ??? 5、把相应的datafile置为online; ??? 6、把相应tablespace改成read write; ???? 具体操作如下： ?SQL> alter database rename file '/opt/oracle/product/10.2.0/oradata/wangxiaoqi/wxq_tbs.dbf' to '/opt/oracle/product/10.2.0/oradata/wangxiaoqi/wxq_tbs2.dbf';
alter database rename file '/opt/oracle/product/10.2.0/oradata/wangxiaoqi/wxq_tbs.dbf' to '/opt/oracle/product/10.2.0/oradata/wangxiaoqi/wxq_tbs2.dbf'
