Oracle19c 創(chuàng)建表空間遇到的坑

更新時間：2021年10月19日 14:25:39 作者：W~C停用

昨天部署好oracle19c后，用以前oracle11g的筆記來創(chuàng)建表空間遇到了坑，今天特此把解決過程分享到腳本之家平臺，感興趣的朋友一起看看吧

#常用的幾個代碼

--查詢臨時表空間
select name from v$tempfile;

--查詢表空間
select name from v$datafile;
修改用戶的密碼
alter user 用戶名 identified by 密碼;

昨天部署好oracle19c后，用以前oracle11g的筆記來創(chuàng)建表空間遇到了坑。這里寫一下總結(jié)。

其實之所以遇到坑是因為相比于oracle11g,oracle19c多了一個CDB和PDB的概念（從12C開始出現(xiàn)）。

#確定表空間文件存儲目錄

[oracle@localhost ~]$ su - oracle
[oracle@localhost ~]$ cd /opt/oracle/oradata/
[oracle@localhost oradata]$ ls
ORCLCDB
[oracle@localhost oradata]$ cd ORCLCDB/
[oracle@localhost ORCLCDB]$ ls
control01.ctl  control02.ctl  ORCLPDB1  pdbseed  redo01.log  redo02.log  redo03.log  sysaux01.dbf  system01.dbf  temp01.dbf  undotbs01.dbf  users01.dbf
[oracle@localhost ORCLCDB]$ mkdir anytxn_v2_dev
[oracle@localhost ORCLCDB]$ cd anytxn_v2_dev/
[oracle@localhost anytxn_v2_dev]$ pwd
/opt/oracle/oradata/ORCLCDB/anytxn_v2_dev

#創(chuàng)建表空間文件

            *
ERROR at line 1:
ORA-65096: invalid common user or role name

此錯誤是因為用戶名稱不符合規(guī)范，Oracle 12C開始引入了CDB與PDB的新特性。sqlplus / as sysdba命令默認登陸的是CDB數(shù)據(jù)庫，而CDB數(shù)據(jù)庫中要求所有新建用戶用戶名必須以c##開頭，否則就會報以上錯誤，在PDB內(nèi)創(chuàng)建用戶則沒有此要求

#修改用戶名后創(chuàng)建用戶

SQL> create user c##anytxn_v2_dev  identified by "jrx12345" default tablespace ANYTXN_V2_DEV_DATA  temporary tablespace ANYTXN_DEV_DATA_TEMP profile DEFAULT;
create user c##anytxn_v2_dev  identified by "jrx12345" default tablespace ANYTXN_V2_DEV_DATA  temporary tablespace ANYTXN_DEV_DATA_TEMP profile DEFAULT

ERROR at line 1:
ORA-65048: error encountered when processing the current DDL statement in
pluggable database ORCLPDB1
ORA-00959: tablespace 'ANYTXN_V2_DEV_DATA' does not exist

原因是在CDB內(nèi)創(chuàng)建用戶分配表空間時，所分配的表空間必須在PDB和CDB中同時存在，否則會報錯。如果是在PDB與CDB有相同表空間的情況下給CDB用戶分配表空間，則會分配CDB的表空間，給用戶PDB的表空間并不受影響。所以要在PDB內(nèi)創(chuàng)建相同的表空間，然后再回CDB創(chuàng)建用戶

如上所示，創(chuàng)建成功，嘗試用新用戶連接數(shù)據(jù)庫
