需求：默認無法直接刪除Oracle的users表空間，直接嘗試刪除會有報錯如下：

SQL> drop tablespace users including contents and datafiles;drop tablespace users including contents and datafiles*ERROR at line 1:ORA-12919: Can not drop the default permanent tablespace

報錯很明確，USERS目前作為數據庫目前默認的永久表空間，暫不支持直接刪除。進一步查詢，看到有很多用戶的確是默認用到了USERS表空間：

SQL>USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------SYSRAC USERS 04-JAN-23SYSTEM SYSTEM 04-JAN-23SYSBACKUP USERS 04-JAN-23AUDSYS USERS 04-JAN-23SYSKM USERS 04-JAN-23SYS SYSTEM 04-JAN-23SYSDG USERS 04-JAN-23OUTLN SYSTEM 04-JAN-23GSMADMIN_INTERNAL SYSAUX 04-JAN-23GSMUSERUSERS 04-JAN-23DIP USERS 04-JAN-23USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------XS$NULLSYSTEM 04-JAN-23REMOTE_SCHEDULER_AGENT USERS 04-JAN-23DBSFWUSER SYSAUX 04-JAN-23ORACLE_OCM USERS 04-JAN-23SYS$UMFUSERS 04-JAN-23DBSNMP SYSAUX 04-JAN-23APPQOSSYS SYSAUX 04-JAN-23GSMCATUSER USERS 04-JAN-23GGSYS SYSAUX 04-JAN-23XDB SYSAUX 04-JAN-23ANONYMOUS SYSAUX 04-JAN-23USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------WMSYS SYSAUX 04-JAN-23OJVMSYSUSERS 04-JAN-23CTXSYS SYSAUX 04-JAN-23MDSYS SYSAUX 04-JAN-23ORDSYS USERS 04-JAN-23ORDDATAUSERS 04-JAN-23ORDPLUGINS USERS 04-JAN-23SI_INFORMTN_SCHEMA USERS 04-JAN-23OLAPSYSSYSAUX 04-JAN-23MDDATA USERS 04-JAN-23APEX_180200 SYSAUX 04-JAN-23USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------FLOWS_FILES SYSAUX 04-JAN-23APEX_PUBLIC_USER USERS 04-JAN-23APEX_INSTANCE_ADMIN_USER USERS 04-JAN-23PDBADMIN USERS 04-JAN-23HR SYSAUX 04-JAN-23JINGYU USERS 06-JAN-23TEAM USERS 01-MAR-2340 rows selected.

但現在XTTS測試，客戶現有源端的users表空間也需要遷移（有用戶數據，注意我們并不推薦在users存放用戶數據）如果真想刪除，也是可以的，就是修改默認表空間，但還需要考慮USERS里面是否有數據要遷移，比較麻煩。現場實施的兄弟提出能否重命名users表空間，這是個好主意，實測是OK，操作也很簡單，一條語句搞定：

SQL> alter tablespace users rename to user1;Tablespace altered.

瞬間執行完成，然后再查用戶的默認表空間，也已經從users已經變成user1：

SQL> select USERNAME, DEFAULT_TABLESPACE, CREATED from dba_users order by 3;USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------SYSRAC USER1 04-JAN-23SYSTEM SYSTEM 04-JAN-23SYSBACKUP USER1 04-JAN-23AUDSYS USER1 04-JAN-23SYSKM USER1 04-JAN-23SYS SYSTEM 04-JAN-23SYSDG USER1 04-JAN-23OUTLN SYSTEM 04-JAN-23GSMADMIN_INTERNAL SYSAUX 04-JAN-23GSMUSERUSER1 04-JAN-23DIP USER1 04-JAN-23USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------XS$NULLSYSTEM 04-JAN-23REMOTE_SCHEDULER_AGENT USER1 04-JAN-23DBSFWUSER SYSAUX 04-JAN-23ORACLE_OCM USER1 04-JAN-23SYS$UMFUSER1 04-JAN-23DBSNMP SYSAUX 04-JAN-23APPQOSSYS SYSAUX 04-JAN-23GSMCATUSER USER1 04-JAN-23GGSYS SYSAUX 04-JAN-23XDB SYSAUX 04-JAN-23ANONYMOUS SYSAUX 04-JAN-23USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------WMSYS SYSAUX 04-JAN-23OJVMSYSUSER1 04-JAN-23CTXSYS SYSAUX 04-JAN-23MDSYS SYSAUX 04-JAN-23ORDSYS USER1 04-JAN-23ORDDATAUSER1 04-JAN-23ORDPLUGINS USER1 04-JAN-23SI_INFORMTN_SCHEMA USER1 04-JAN-23OLAPSYSSYSAUX 04-JAN-23MDDATA USER1 04-JAN-23APEX_180200 SYSAUX 04-JAN-23USERNAME DEFAULT_TABLESPACE CREATED------------------------------ ------------------------------ ---------FLOWS_FILES SYSAUX 04-JAN-23APEX_PUBLIC_USER USER1 04-JAN-23APEX_INSTANCE_ADMIN_USER USER1 04-JAN-23PDBADMIN USER1 04-JAN-23HR SYSAUX 04-JAN-23JINGYU USER1 06-JAN-23TEAM USER1 01-MAR-2340 rows selected.

查詢數據庫默認永久表空間也都變成了USER1：

SQL> SELECT PROPERTY_VALUEFROM DATABASE_PROPERTIESWHERE PROPERTY_NAME = 'DEFAULT_PERMANENT_TABLESPACE'; 2 3PROPERTY_VALUE------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------USER1
