文章快速说明索引

学习目标：

目的：接下来这段时间我想做一些兼容Oracle数据库Real Application Testing (即：RAT)上的一些功能开发，本专栏这里主要是学习以及介绍Oracle数据库功能的使用场景、原理说明和注意事项等，基于PostgreSQL数据库的功能开发等之后 由新博客进行介绍和分享！

从种子PDB来创建

第一步，查看pdb状态，如下：

[oracle@dbserver ~]$ sqlplus / as sysdba

	 3 ORCLPDB			  READ WRITE NO

如上，seed pdb 在数据库cdb启动时处于read only的状态！

第二步，查看其数据文件，如下：

SQL> set line 1000
SQL> col name format a100
SQL> select name, con_id from v$datafile order by con_id;

第三步，创建新的PDB目录，如下：

-- mkdir capturepdb
-- mkdir replaypdb
[oracle@dbserver ~]$ cd /home/oracle/oracle19c/oradata/ORCL/
[oracle@dbserver ORCL]$ ls
capturepdb  control01.ctl  control02.ctl  orclpdb  pdbseed  redo01.log  redo02.log  redo03.log  replaypdb  sysaux01.dbf  system01.dbf  temp01.dbf  undotbs01.dbf  users01.dbf
[oracle@dbserver ORCL]$ 
[oracle@dbserver ORCL]$ ls capturepdb/
[oracle@dbserver ORCL]$ 
[oracle@dbserver ORCL]$ ls replaypdb/
[oracle@dbserver ORCL]$

第四步，创建capturepdb，如下：

SQL> create pluggable database capturepdb admin user sysdba identified by 123456 roles=(connect) file_name_convert=('/home/oracle/oracle19c/oradata/ORCL/pdbseed','/home/oracle/oracle19c/oradata/ORCL/capturepdb');

Pluggable database created.

第五步，打开上面创建的pdb，如下：

SQL> alter session set container = capturepdb;

Session altered.

SQL> alter pluggable database capturepdb open;

Pluggable database altered.

SQL> show pdbs;

    CON_ID CON_NAME			  OPEN MODE  RESTRICTED

/home/oracle/oracle19c/oradata/ORCL/capturepdb/sysaux01.dbf						      4

SQL> select file_id, file_name, tablespace_name from cdb_data_files;

   FILE_ID FILE_NAME												TABLESPACE_NAME
---------- ---------------------------------------------------------------------------------------------------- --------------------
	21 /home/oracle/oracle19c/oradata/ORCL/capturepdb/system01.dbf						SYSTEM
	22 /home/oracle/oracle19c/oradata/ORCL/capturepdb/sysaux01.dbf						SYSAUX
	23 /home/oracle/oracle19c/oradata/ORCL/capturepdb/undotbs01.dbf 					UNDOTBS1

SQL>

此时再新建一个会话，如下：

SQL> show pdbs;

    CON_ID CON_NAME			  OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
	 2 PDB$SEED			  READ ONLY  NO
	 3 ORCLPDB			  READ WRITE NO
	 4 CAPTUREPDB			  READ WRITE NO
SQL> col file_name for a100;
SQL> col tablespace_name for a20;

   FILE_ID FILE_NAME												TABLESPACE_NAME
---------- ---------------------------------------------------------------------------------------------------- --------------------
	23 /home/oracle/oracle19c/oradata/ORCL/capturepdb/undotbs01.dbf 					UNDOTBS1

12 rows selected.

第六步，配置tnsnames.ora，并建立连接，如下：

[oracle@dbserver ~]$ vim  ./oracle19c/product/19c/dbhome_1/network/admin/tnsnames.ora
[oracle@dbserver ~]$ 
[oracle@dbserver ~]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 oracle
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 oracle
[oracle@dbserver ~]$ 
[oracle@dbserver ~]$ cat  ./oracle19c/product/19c/dbhome_1/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /home/oracle/oracle19c/product/19c/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = oracle)(PORT = 1521))


ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

PDBORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ORCLPDB)
    )
  )

CAPTUREPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = capturepdb)
    )
  )
[oracle@dbserver ~]$ cat /home/oracle/oracle19c/product/19c/dbhome_1/network/admin/listener.ora
# listener.ora Network Configuration File: /home/oracle/oracle19c/product/19c/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

ORCL =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oracle)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
SID_LIST_LISTENER =  
(SID_LIST =  
  (SID_DESC =  
  (GLOBAL_DBNAME = orcl)
  (SID_NAME = orcl)
  )
)
[oracle@dbserver ~]$

然后重启了一下监听，如下：

[oracle@dbserver ~]$ lsnrctl stop ; lsnrctl start
...
[oracle@dbserver ~]$ lsnrctl status
...

在这里插入图片描述

[oracle@dbserver ~]$ sqlplus sys/123456@capturepdb as sysdba

第七步，创建并指定默认表空间，如下：

SQL> col file_name for a100;
SQL> col tablespace_name for a20;
SQL> 
SQL> select file_name, tablespace_name from cdb_data_files;

FILE_NAME											     TABLESPACE_NAME

SQL> create tablespace users datafile '/home/oracle/oracle19c/oradata/ORCL/capturepdb/user.dbf' size 50M autoextend on next 1G maxsize 5G;

Tablespace created.

从本地PDB来克隆

从容器数据库中克隆本地capturepdb来创建replaypdb，如下：

第一步，以只读方式打开capturepdb，如下：

[oracle@dbserver ~]$ sqlplus / as sysdba

第二步，查看数据文件，并创建新的PDB目录，如下：

SQL> set line 1000;
SQL> col name format a100;
SQL> 
SQL> select name, con_id from v$datafile where con_id = 4;

NAME													 CON_ID
---------------------------------------------------------------------------------------------------- ----------

SQL>

[oracle@dbserver ~]$ cd /home/oracle/oracle19c/oradata/ORCL/
[oracle@dbserver ORCL]$ 
[oracle@dbserver ORCL]$ ls replaypdb/
[oracle@dbserver ORCL]$

第三步，克隆 如下：

[oracle@dbserver ~]$ sqlplus / as sysdba
