oracle 12c 初步操作

查看是否为cdb

SQL> select name,cdb,open_mode,con_id from v$database;

NAME                        CDB       OPEN_MODE                                                        CON_ID

查看当前容器

SQL> show con_name

进入PDB做一些日常操作

SQL> select FILE_NAME,TABLESPACE_NAME ,file_id from dba_data_files;

FILE_NAME                                                                            TABLESPACE_NAME                 FILE_ID

创建PDB

SQL> CREATE PLUGGABLE DATABASE pdbtest1 ADMIN USER pdbtest1admin IDENTIFIED BY pdbtest1admin
  2  STORAGE (MAXSIZE 2G MAX_SHARED_TEMP_SIZE 100M)
  3  DEFAULT TABLESPACE test1tb1
