现在需要在一个测试环境创建1个为AL32UTF8的PDB,2个ZHS16GBK的PDB

这种情况下,必须先创建的CDB为AL32UTF8,下面是具体步骤:

1.AL32UTF8的pdb在建实例的时候一起创建完成

2.创建第一个ZHS16GBK的PDB cdr,通过pdbseed来克隆:

SQL> create pluggable database cdr admin user suq identified by suq file_name_convert=('pdbseed','cdr');

SQL> alter pluggable database cdr open;

SQL> alter session set container=cdr;

SQL> alter system enable restricted session;

SQL> alter pluggable database cdr character set internal_use zhs16gbk;

SQL> shutdown immediate

SQL> startup

3.创建第二个pdb cdrlog,通过克隆cdr来实现:

SQL> create pluggable database cdrlog from cdr file_name_convert=('cdr','cdrlog');

SQL> alter pluggable database cdrlog open;

SQL> alter pluggable database all save state;

4.检查每个pdb的字符集

SQL> show pdbs;

    CON_ID CON_NAME              OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

     2 PDB$SEED              READ ONLY  NO

     3 DBSERVER              READ WRITE NO

     4 CDR                  READ WRITE NO

     5 CDRLOG              READ WRITE NO

SQL> alter session set container=dbserver;

Session altered.

SQL> select userenv('LANGUAGE') from dual;

USERENV('LANGUAGE')

----------------------------------------------------

AMERICAN_AMERICA.AL32UTF8

SQL> alter session set container=cdr;

Session altered.

SQL> select userenv('LANGUAGE') from dual;

USERENV('LANGUAGE')

----------------------------------------------------

AMERICAN_AMERICA.ZHS16GBK

SQL> alter session set container=cdrlog;

Session altered.

SQL> select userenv('LANGUAGE') from dual;

USERENV('LANGUAGE')

----------------------------------------------------

AMERICAN_AMERICA.ZHS16GBK
