Oracle 12C -- 使用local PDB克隆新的PDB

1.将用于克隆的PDB至于只读状态：startup open read only

SQL> select con_id,name,open_mode from v$pdbs;

    CON_ID NAME                           OPEN_MODE
---------- ------------------------------ ----------
         2 PDB$SEED                       READ ONLY
         3 PDB1                           MOUNTED
         4 P4                             MOUNTED

SQL> alter session set container=pdb1;
SQL> alter database open read only;

2.登陆CDB

SQL> connect /as sysdba
SQL> create pluggable database pdb2 from pdb1 file_name_convert=('pdb1','pdb2');
SQL> alter session set container=pdb2;
SQL> startup
SQL> select con_id,name,open_mode from v$pdbs;

    CON_ID NAME                           OPEN_MODE
---------- ------------------------------ ----------
         2 PDB$SEED                       READ ONLY
         3 PDB1                           READ ONLY
         4 P4                             MOUNTED
         5 PDB2                           READ WRITE

SQL> 

3.打开原来的PDB

SQL> alter session set container=pdb1;
SQL> shutdown
SQL> startup
