管理多租户环境之PDB快照

PDB 快照

快照是数据库基于时间点的完整镜像，主要用于快速恢复和PDB复制。

利用PDB快照创建新PDB的语法如下：

可以手动生成快照，也可以指定每隔多长时间自动生成一次快照，最多可以存储8个快照。

创建PDB快照

1. 设置自动创建PDB快照

可以设置每隔一段时间自动创建一个PDB。

EVERY snapshot_interval [ MINUTES | HOURS ]

查看当前PDB快照模式

SQL>
SQL> SELECT SNAPSHOT_MODE "S_MODE",SNAPSHOT_INTERVAL/60 "SNAP_INT_HRS" FROM DBA_PDBS;S_MODE SNAP_INT_HRS
------ ------------
MANUALSQL>

设置每隔24小时就创建一个快照，需要在相应的PDB下执行命令：


SQL>
SQL> ALTER PLUGGABLE DATABASE SNAPSHOT MODE EVERY 24 HOURS;Pluggable database altered.SQL>

再次查看快照模式，代码如下：

SQL> SELECT SNAPSHOT_MODE "S_MODE",SNAPSHOT_INTERVAL/60 "SNAP_INT_HRS" FROM DBA_PDBS;S_MODE SNAP_INT_HRS
------ ------------
AUTO             24SQL>

2.手动创建PDB快照

SQL> show con_name;CON_NAME
------------------------------
CDB$ROOT
SQL> SQL> alter session set container=PDB1;Session altered.SQL> show pdbs;CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------3 PDB1                           READ WRITE NO
SQL> alter pluggable database snapshot CNDBAPDB5_20221202;Pluggable database altered.SQL>

查看快照信息

SQL> set LINESIZE 150
SQL> col con_name format a10
SQL> col snapshot_name format a30
SQL> col full_snapshot_path format a55
SQL> col snap_scn default
SQL> select con_id,con_name,snapshot_name,snapshot_scn as snap_scn,full_snapshot_path from dba_pdb_snapshots order by snap_scn;CON_ID CON_NAME   SNAPSHOT_NAME                    SNAP_SCN FULL_SNAPSHOT_PATH
------ ---------- ------------------------------ ---------- -------------------------------------------------------3 PDB1       CNDBAPDB5_20221202               18991475 /u02/oradata/snap_2714456025_18991475.pdb3 PDB1       SNAP_2714456025_1122376588       18997049 /u02/oradata/snap_2714456025_18997049.pdbSQL>

删除快照

可以一个一个地删除快照，也可以一次性删除所有快照。

SQL>
SQL> select con_id,con_name,snapshot_name,snapshot_scn as snap_scn,full_snapshot_path from dba_pdb_snapshots order by snap_scn;CON_ID CON_NAME   SNAPSHOT_NAME                    SNAP_SCN FULL_SNAPSHOT_PATH
------ ---------- ------------------------------ ---------- -------------------------------------------------------3 PDB1       CNDBAPDB5_20221202               18991475 /u02/oradata/snap_2714456025_18991475.pdb3 PDB1       SNAP_2714456025_1122376588       18997049 /u02/oradata/snap_2714456025_18997049.pdbSQL> ALTER PLUGGABLE DATABASE DROP SNAPSHOT SNAP_2714456025_1122376588;Pluggable database altered.SQL> select con_id,con_name,snapshot_name,snapshot_scn as snap_scn,full_snapshot_path from dba_pdb_snapshots order by snap_scn;CON_ID CON_NAME   SNAPSHOT_NAME                    SNAP_SCN FULL_SNAPSHOT_PATH
------ ---------- ------------------------------ ---------- -------------------------------------------------------3 PDB1       CNDBAPDB5_20221202               18991475 /u02/oradata/snap_2714456025_18991475.pdbSQL>

删除所有快照，将MAX_PDB_SNAPSHOTS参数设置为0就会自动删除该PDB的所有快照，删除速度也快很多。


SQL> select con_id,con_name,snapshot_name,snapshot_scn as snap_scn,full_snapshot_path from dba_pdb_snapshots order by snap_scn;CON_ID CON_NAME   SNAPSHOT_NAME                    SNAP_SCN FULL_SNAPSHOT_PATH
------ ---------- ------------------------------ ---------- -------------------------------------------------------3 PDB1       CNDBAPDB5_20221202               18991475 /u02/oradata/snap_2714456025_18991475.pdbSQL> ALTER PLUGGABLE DATABASE SET MAX_PDB_SNAPSHOTS=0;Pluggable database altered.SQL> select con_id,con_name,snapshot_name,snapshot_scn as snap_scn,full_snapshot_path from dba_pdb_snapshots order by snap_scn;no rows selectedSQL> ALTER PLUGGABLE DATABASE SET MAX_PDB_SNAPSHOTS=8;Pluggable database altered.SQL>

监控CDB和PDB

容器数据对象，包括：

v$视图
GV$视图
CDB_视图
DBA_HIST*视图

容器数据对象用于显示关于多租户的相关信息。每个容器数据对象通过CON_ID 来区分不同的容器

{CDB|DBA}_PDBS

显示与CDB相关的PDB的信息，包括每个PDB的状态
