Oracle multi-tenant (ofm creates default table space and default table space clone)

使用ofm创建PDB2，不指定表空间
CREATE PLUGGABLE DATABASE pdb2
ADMIN USER pdb_adm IDENTIFIED BY aabb123;
ALTER PLUGGABLE DATABASE pdb2 OPEN READ WRITE;

ALTER SESSION SET CONTAINER = pdb2;
SELECT tablespace_name
FROM dba_tablespaces;

SELECT property_value
FROM database_properties
WHERE property_name = ‘DEFAULT_PERMANENT_TABLESPACE’;

创建PDB指定表空间
ALTER SESSION SET CONTAINER = cdb$root;
CREATE PLUGGABLE DATABASE pdblh ADMIN USER pdb_adm IDENTIFIED BY aabb123
DEFAULT TABLESPACE pdblh DATAFILE SIZE 1M AUTOEXTEND ON NEXT 1M;
ALTER PLUGGABLE DATABASE pdblh OPEN;

ALTER SESSION SET CONTAINER = pdblh;
SELECT tablespace_name
FROM dba_tablespaces;

SELECT property_value
FROM database_properties
WHERE property_name = ‘DEFAULT_PERMANENT_TABLESPACE’;

Specify the default tablespace when cloning
Create a new PDB
ALTER SESSION SET CONTAINER = cdb$root;
CREATE PLUGGABLE DATABASE pdbzs ADMIN USER pdb_adm IDENTIFIED BY aabb123
DEFAULT TABLESPACE zs DATAFILE SIZE 1M AUTOEXTEND ON NEXT 1M;
ALTER PLUGGABLE OPENs;


connect to pdbzs View
ALTER SESSION SET CONTAINER = pdbzs;
SELECT property_value
FROM database_properties
WHERE property_name ='DEFAULT_PERMANENT_TABLESPACE';

create table space
show CON_NAME
CREATE TABLESPACE test_ts DATAFILE SIZE 1M AUTOEXTEND ON NEXT 1M

view PDBZS table space

克隆PDB指定默认表空间
ALTER SESSION SET CONTAINER = cdb$root;
show CON_NAME
show pdbs
CREATE PLUGGABLE DATABASE pdblisi FROM pdbzs
DEFAULT TABLESPACE test_ts;
ALTER PLUGGABLE DATABASE pdblisi OPEN;

ALTER SESSION SET CONTAINER = PDBLISI;
show CON_NAME
SELECT tablespace_name
FROM dba_tablespaces;

SELECT property_value
FROM database_properties
WHERE property_name = ‘DEFAULT_PERMANENT_TABLESPACE’;
