Oracle DataGuard 之--Physical DG转换Logical DG
一、Physical DG和Logical DG
Physical Standby使用的是Media Recovery 技术,在数据块级别进行恢复,这种方式没有数据类型的限制,可以保证两个数据库完全一致。 Physical Standby数据库只能在Mount 状态下进行恢复,也可以是打开,但只能已只读方式打开,并且打开时不能执行恢复操作。
Logical Standby使用的是Logminer 技术,通过把日志内容还原成SQL 语句,然后SQL引擎执行这些语句,Logminer Standby不支持所有数据类型,可以在视图DBA_LOGSTDBY_UNSUPPORTED 中查看不支持的数据类型,如果使用了这种数据类型,则不能保证数据库完全一致。LogicalStandby数据库可以在恢复的同时进行读写操作。
二、物理备库升级逻辑备库准备
1) 确认主库包含逻辑STANDBY支持的表和数据类型
1、 逻辑STANDBY支持的数据类型:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
|
CHAR
NCHAR
VARCHAR2
and
VARCHAR
NVARCHAR2
NUMBER
DATE
TIMESTAMP
TIMESTAMP WITH TIME ZONE
TIMESTAMP WITH LOCAL TIME ZONE
INTERVAL YEAR TO MONTH
INTERVAL DAY TO SECOND
RAW
CLOB
BLOB
|
2、逻辑STANDBY不支持的数据类型:NCLOB, LONG, LONG RAW, BFILE, ROWID, and UROWID
3、逻辑STANDBY不支持的表和序列:
1
2
3
4
5
|
Tables
and
sequences
in
the SYS schema
Tables
with
unsupported datatypes
Tables used to support functional indexes
Tables used to support materialized views
Global temporary tables
|
逻辑STANDBY不支持的表和列可以通过视图dba_logstdby_unsupported来查询:
SELECT * FROM DBA_LOGSTDBY_UNSUPPORTED;
4、逻辑STANDBY不支持的SQL语句操作:
1
2
3

2)通过物理备库升级到逻辑备库

关于logical standy上的DDL/DML修改
在logical standby环境下,备库基本上是一个独立的库,如果要在备库,以非sys用户对备库的数据进行DML修改,就会报错 ora-16224
au10qapap0tels2:ARS2AP:/opt/app/oracle/admin> oerr ora 16224
16224, 00000, "Database Guard is enabled"
// *Cause: Operation could not be performed because database guard is enabled
// *Action: Verify operation is correct and disable database guard
我们需要在备库做一些操作,以避免报错。
检查备库状态,我们发现是处于standby状态:

11
|
SQL> select guard_status from v$database;
GUARD_S
-------
STANDBY
改其状态为none:
SQL> alter database guard none;
Database altered。
SQL> select guard_status from v$database;
GUARD_S
-------
NONE
|
修改回standby状态:
alter database guard standby;
在standby或all状态下,所有非sys用户,都无法对logical standby的数据进行修改,关于alter database guard [standby|all|none] 几个参数的解释如下:
ALTER DATABASE GUARD ALL - prevents users making any changes - DEFAULT
ALTER DATABASE GUARD STANDBY - prevents users making changes to data maintained by data guard sql apply,即对DBMS_LOGSTDBY.SKIP 跳过的表可进行DML操作,而其他需要SQL APPLY的对象都不能进行变更操作。
ALTER DATABASE GUARD NONE - normal security
在逻辑备库上转换数据库保护模式(最大保护转换为最大性能)
