Oracle 建立PDB-from Scratch
Oracle 建立PDB-from Scratch
一：Creating a PDB from Scratch
從PDB$SEED 建立新PDB
1 ：資料庫版本
Oracle Database 19 c Enterprise Edition Release 19.0 .0.0.0 - Production
Version 19.3 .0.0.0
2 ：檢視pdbs
SQL > show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 CJCPDB01 READ WRITE NO
3 ：檢視資料檔案
---CDB$ROOT
SQL > select file_name from dba_data_files order by 1 ;
FILE_NAME
--------------------------------------------------------------------------------
/ u01 / app / oracle12 / oradata / cjcdb01 / sysaux01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / system01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / undotbs01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / users01.dbf
---CJCPDB
SQL > alter session set container = cjcpdb01 ;
Session altered.
SQL > select file_name from dba_data_files order by 1 ;
FILE_NAME
--------------------------------------------------------------------------------
/ u01 / app / oracle12 / oradata / cjcdb01 / cjcpdb01 / cjctbs01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / cjcpdb01 / sysaux01.dbf

/ u01 / app / oracle12 / oradata / cjcdb01 / cjcpdb01 / undotbs01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / cjcpdb01 / users01.dbf
---PDB$SEED
SQL > alter session set container = pdb$seed ;
Session altered.
SQL > select file_name from dba_data_files ;
FILE_NAME
--------------------------------------------------------------------------------
/ u01 / app / oracle12 / oradata / cjcdb01 / pdbseed / system01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / pdbseed / sysaux01.dbf
/ u01 / app / oracle12 / oradata / cjcdb01 / pdbseed / undotbs01.dbf
4 ：建立PDB
--- 建立目錄
[oracle @ cjcos oradata]$ pwd
/ u01 / app / oracle12 / oradata
[oracle @ cjcos oradata]$ mkdir cjcpdb02
--- 建立PDB
SQL >
CREATE PLUGGABLE DATABASE cjcpdb02
ADMIN USER cjc IDENTIFIED BY oracle
FILE_NAME_CONVERT = ( '/u01/app/oracle12/oradata/cjcdb01/pdbseed/' ,
'/u01/app/oracle12/oradata/cjcpdb02/' );
Pluggable database created.

------------------------------------ ----------- ------------------------------
db_create_file_dest string
--- 建立PDB時指定FILE_NAME_CONVERT即可
