檢視 CDB&PDBs 資訊（ SQL*PLUS ）

V$ ， GV$ ， CDB_ ， CONTAINER_DATA 的屬性決定了對哪些 PDB 可見；

每個容器資料物件都有 CON_ID 列，列值 代表整個 CDB 可見， 1 代表 root 物件， 2 代表 seed 物件 ,3~254 代表 PDB 物件；

以下檢視的行為不同於其他 [G]V$ 檢視 :

·         [G]V$SYSSTAT

·         [G]V$SYS_TIME_MODEL

·         [G]V$SYSTEM_EVENT

·         [G]V$SYSTEM_WAIT_CLASS

從 root 查詢時，這些檢視返回例項範圍的資料，返回的每一行 CON_ID 列中都有 。但是，您可以查詢與其他容器資料物件行為相同的等效檢視。以下檢視可以為 CDB 中的每個容器返回特定的資料 :[G]V$CON_SYSSTAT 、 [G]V$CON_SYS_TIME_MODEL 、 [G]V$CON_SYSTEM_EVENT 和 [G]V$CON_SYSTEM_WAIT_CLASS 。

1.    CDB 中的檢視 views

Table 43-2 Views for a CDB

View

Description

Container data objects, including:

l   V$  views

l   GV$  views

l   CDB_  views

l   DBA_HIST*  views

Container data objects can display   information about multiple PDBs. Each container data object includes a  CON_ID  column to identify containers.

There is a  CDB_  view for each corresponding  DBA_  view.

{CDB|DBA}_PDBS

Displays information about the   PDBs associated with the CDB, including the status of each PDB.

CDB_PROPERTIES

Displays the permanent properties   of each container in a CDB.

{CDB|DBA}_PDB_HISTORY

Displays the history of each PDB.

{CDB|DBA}_CONTAINER_DATA

Displays information about the   user-level and object-level  CONTAINER_DATA  attributes specified in the CDB.

{CDB|DBA}_HIST_PDB_INSTANCE

Displays the PDBs and instances in   the Workload Repository.

{CDB|DBA}_PDB_SAVED_STATES

{USER|ALL|DBA|CDB}_OBJECTS

Displays information about   database objects, and the  SHARING column shows whether a database object is a metadata-linked   object, an object-linked object, or a standalone object that is not linked to   another object.

{ALL|DBA|CDB}_SERVICES

Displays information about   database services, and the  PDB column shows the name of the PDB associated with each service.

{USER|ALL|DBA|CDB}_VIEWS

{USER|ALL|DBA|CDB}_TABLES

The  CONTAINER_DATA  column shows whether the view or table is a container   data object.

{USER|ALL|DBA|CDB}_USERS

The  COMMON  column shows whether a user is a common user or a local   user.

{USER|ALL|DBA|CDB}_ROLES

{USER|ALL|DBA|CDB}_COL_PRIVS

{USER|ALL|DBA|CDB}_VIEWS

The  ORIGIN_CON_ID  column shows the ID of the container from which the row   originates.

[G]V$DATABASE

Displays information about the   database from the control file. If the database is a CDB, then CDB-related   information is included.

[G]V$CONTAINERS

Displays information about the   containers associated with the current CDB, including the root and all PDBs.

[G]V$PDBS

Displays information about the   PDBs associated with the current CDB, including the open mode of each PDB.

[G]V$PDB_INCARNATION

Displays displays information   about all PDB incarnations. Oracle creates a new PDB incarnation whenever a   PDB is opened with the  RESETLOGS  option.

[G]V$SYSTEM_PARAMETER

[G]V$PARAMETER

Displays information about   initialization parameters, and the  ISPDB_MODIFIABLE  column shows whether a parameter can be modified for a   PDB.

 

2.    如何判斷是否 CDB

SELECT CDB FROM V$DATABASE;

3.    查詢 CDB 中的容器資訊
