1Z0-063第2章
1Z0-05219章(上完19章),1Z0-05321章(上完21章)和1Z0-063多租户部分共9章(上2
总共上完全部49章中的42
在多租户的根容器上查v$视图:

  1. select   d.CON_ID,d.NAME,d.OPEN_MODE,d.CDB
  2. from v$database d;
  3. 显示成容器0,不是容器1。容器0代表公共的。
复制代码
  1. select i.INSTANCE_MODE, i.INSTANCE_NAME,i.CON_ID
  2.   from v$instance i;
  3. 显示成容器0,不是容器1。容器0代表公共的。
复制代码
  1.     select s.CON_ID,s.NAME,s.PDB
  2.    from v$services s;
复制代码
  1.   select  p.CON_ID,p.NAME,p.OPEN_MODE
  2.   from v$pdbs p;
  3.   
  4.   
  5.      select  sys_context('userenv','con_id') from dual;
  6.          
  7.       select  sys_context('userenv','con_name') from dual;
复制代码
  1.   select  * from cdb_pdbs;
复制代码
  1. select  * from v$logfile;
  2. 显示成容器0,不是容器1。容器0代表公共的。
复制代码
  1.           select * from v$controlfile;
  2. 显示成容器0,不是容器1。容器0代表公共的。
复制代码
  1.           select  c.CON_ID,c.FILE_NAME,c.STATUS from
  2.   cdb_data_files c;

  3. 所有CDB视图,都可以在插件数据库中查。如果在根容器上查,都不会显示成容器0,而是显示成容器1。
复制代码
  1.    select t.CON_ID,t.NAME,d.NAME,d.STATUS
  2.   from v$tablespace t, v$datafile d
  3.   where t.TS#=d.TS#  and t.CON_ID=d.CON_ID
  4.   order by 1,2;

  5. 以上语句在插件库中查,能显示包括UNDO表空间在类的插件数据库所有文件,UNDO表空间的文件显示成容器0(公共)。
复制代码
  1.       select t.CON_ID,t.NAME,d.NAME,d.STATUS
  2.   from v$tablespace t, v$tempfile d
  3.   where t.TS#=d.TS#  and t.CON_ID=d.CON_ID
  4.   order by 1,2;

  5. 以上语句能看见种子的临时文件。
复制代码
  1.    select c.COMMON,c.CON_ID,c.DEFAULT_TABLESPACE,
  2.   c.TEMPORARY_TABLESPACE,c.INITIAL_RSRC_CONSUMER_GROUP,c.USERNAME
  3.    from cdb_users c
  4.    where c.USERNAME='SYSTEM';

  5. 除了cdb_pdbs以外,其他cdb_视图都不显示种子。
复制代码
  1.       select c.COMMON,c.CON_ID,c.DEFAULT_TABLESPACE,
  2.   c.TEMPORARY_TABLESPACE,c.INITIAL_RSRC_CONSUMER_GROUP,c.USERNAME
  3.    from cdb_users c
  4.    where c.COMMON='NO';

  5. 根容器上是没有本地用户和本地角色的。根容器唯一可能有“本地”含义的东西就是:对象权限的本地授权。
复制代码

根容器上是没有系统权限的本地授权的:
Screenshot-1.png

  1. select c.COMMON,c.CON_ID,c.DEFAULT_TABLESPACE,
  2.   c.TEMPORARY_TABLESPACE,c.INITIAL_RSRC_CONSUMER_GROUP,c.USERNAME
  3.    from cdb_users c
  4.    where c.COMMON='NO';

  5. 种子不算,在没有插件数据库的情况下是没有本地用户,没有本地角色的。
复制代码
  1. select  distinct b.STATUS, b.CON_ID
  2.   from v$bh b
  3.   order by 2;

  4. 内存是各个容器共享的。

SQLPLUS创建插件数据库的语句:
  1. create pluggable database pdb2_1
  2. admin user pdb2_1_admin
  3. identified by oracle_4U roles=(connect)
  4. file_name_convert=('/u01/app/oracle/oradata/cdb2/pdbseed',
  5. '/u01/app/oracle/oradata/cdb2/pdb2_1');


  6. select  con_id, open_mode , name
  7. from v$pdbs;

  8. alter pluggable database pdb2_1 open ;

  9. select  con_id, open_mode , name
  10. from v$pdbs;

SQLPLUS命令删除插件数据库:

  1. select  con_id, open_mode , name from v$pdbs;

  2. drop pluggable database pdb2_1 including datafiles;

  3. alter pluggable database pdb2_1  close immediate ;

  4. drop pluggable database pdb2_1 including datafiles;
复制代码

P60以下这句是完全不需要的:
  1. alter system set db_create_file_dest =
  2. '/u01/app/oracle/oradata/cdb2/pdb2_1' scope=both;
复制代码
原因是因为我们在SQL Developer中制定和命令行等效的语句:
file_name_convert=('/u01/app/oracle/oradata/cdb2/pdbseed',
'/u01/app/oracle/oradata/cdb2/pdb2_1')

Screenshot-3.png

  1. select  con_id, name , open_mode
  2. from v$pdbs;

  3. select  t.con_id, t.name , d.name , d.status
  4. from v$tablespace t, v$datafile d
  5. where t.ts#=d.ts# and t.con_id=d.con_id
  6. order by 1,2;

  7. select  t.con_id, t.name , d.name , d.status
  8. from v$tablespace t, v$tempfile d
  9. where t.ts#=d.ts# and t.con_id=d.con_id
  10. order by 1,2;
复制代码
准备做pdb2_2,书P64页莫名其妙选用OMF方式,非常怪:
以下演示与P64页不同。

  1. [oracle@station26 cdb2]$ mkdir pdb2_2
复制代码
在12.1.0.2后,克隆时,源头库已经可以不停机了(P65页有停机)

  1. select con_id, name , open_mode
  2. from v$pdbs;

  3. create pluggable database pdb2_2 from pdb2_1
  4. file_name_convert=('/u01/app/oracle/oradata/cdb2/pdb2_1',
  5. '/u01/app/oracle/oradata/cdb2/pdb2_2');

  6. alter pluggable database pdb2_2 open ;

  7. select con_id, name , open_mode
  8. from v$pdbs;
复制代码

书上做PDB2_2是这样OMF的:
