• 在多租户(容器)数据库中如何创建PDB:方法6 DBCA本地克隆PDB


    基于版本:19c (12.2.0.3) AskScuti

    创建方法:DBCA静默本地克隆PDB。根据 CDB1 中的 PDB1 克隆出 CDB1 中的 PDB_CLONE

    对应路径:Creating a PDB --> Cloning --> 无对应路径(DBCA)

    在容器数据库CDB里面如何创建PDB,官方文档给出了一张创建PDB技术选项图,图片如下:

    注意:DBCA静默克隆建库,方法没有在此图片上显示,本文将DBCA方法记在Cloning下面

    另外:DBCA克隆或重定位PDB,不支持开启了OMF的CDB, CDB1和CDB2必须都为归档模式。

    1. 概述

    2. CDB1:PDB1确认用户和数据

    3. CDB1进行DBCA本地克隆

    4. CDB1验证

    1. 概述

    通过DBCA工具进行静默本地克隆,根据 CDB1 中的 PDB1 克隆出 PDB_CLONE

    CDB1PDB1)中有个用户SCOTT,下面有张表 EMP

    CDB1下面的 PDB1 静默创建克隆出 PDB_CLONE,并验证 PDB_CLONE 中是否存在SCOTT用户及EMP表。

    2. CDB1:PDB1确认用户和数据

    [oracle@erp ~]$ rlwrap sqlplus / as sysdba

    SQL> show pdbs
    
        CON_ID CON_NAME  OPEN MODE  RESTRICTED
    ---------- --------- ---------- ----------
         2 PDB$SEED      READ ONLY  NO
         3 PDB1          READ WRITE NO
    SQL> alter session set container=pdb1;
    
    Session altered.
    
    SQL> select count(1) from scott.emp;
    
      COUNT(1)
    ----------
        14

    3. CDB1进行DBCA本地克隆

    dbca -silent -createPluggableDatabase -sourceDB cdb1 -createPDBFrom PDB -pdbName pdb_clone -sourcePDB pdb1

    过程

    [oracle@erp ~]$ dbca -silent -createPluggableDatabase -sourceDB cdb1 -createPDBFrom PDB -pdbName pdb_clone -sourcePDB pdb1
    Prepare for db operation

    Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/cdb1/pdb_clone/cdb1.log" for further details.

    4. CDB1验证

    [oracle@erp ~]$ rlwrap sqlplus / as sysdba
