ORACLE 在AZURE云上准备预发布数据库环境

1，搭建准备

需要搭建一个预发布环境，因为线上采用的是rman备份，所以会有rman备份集合，但是rman出来的备份集合，每次恢复过程中都会出现各种各样的细节问题，最近数据库升级了小版本号，到了11.2.0.4，所以记录下来这次rman的恢复过程，以备后来参考，大概流程是

（1）copy备份集合到临时库；

（2）关闭临时库

（3）恢复控制文件

（4）注册备份集合目录

（5）restore database、recovery database；

（6）open打开数据库

2、去生产环境中copy备份文件

去备份文件服务器上，拷贝，需要拷贝数据集、控制文件到临时库

拷贝备份集合，这里包括了备份的归档日志、控制文件、数据文件等等：scp -r 2017-04-22 10.10.10.115:/data/

然后到临时库服务器，赋予Oracle执行权限：chown -R oracle.oinstall /data/*

3、关闭临时库，并以nomount方式打开

RMAN> shutdown immediate;

database dismounted
Oracle instance shut down

RMAN>

RMAN>

RMAN> startup nomount;

connected to target database (not started)
Oracle instance started

Redo Buffers                  19742720 bytes

RMAN> exit

4、在临时库上恢复控制文件

去生产环境查询控制文件路径

SQL> select name from v$controlfile;

NAME
--------------------------------------------------------------------------------
/oracle/app/oracle/fast_recovery_area/powerdes/control02.ctl

SQL>

去预发布库上，恢复控制文件，在rman命令行界面，执行如下命令

恢复命令：

restore controlfile to '/oracle/app/oracle/fast_recovery_area/powerdes/control02.ctl' from '/oracle/2017-04-22/c-3391761643-20170422-01';

执行过程

RMAN> restore controlfile to '/oracle/app/oracle/fast_recovery_area/powerdes/control02.ctl' from '/oracle/2017-04-22/c-3391761643-20170422-01';

Starting restore at 26-APR-17
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=5665 device type=DISK

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
Finished restore at 26-APR-17

RMAN>

5、将预发布库启动到mount

alter database mount;
RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

RMAN>

6、开始注册备份集

命令：

catalog start with ‘/oracle/2017-04-22/’;

执行过程

RMAN> catalog start with '/oracle/2017-04-22/';

Starting implicit crosscheck backup at 26-APR-17
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=5665 device type=DISK

Finished implicit crosscheck backup at 26-APR-17

7、进行restore database恢复操作

接下来开始执行restore恢复操作，将数据从备份集写入到磁盘上的数据文件里面，还原已经备份的数据文件

命令：

restore database;

执行过程，执行时间比较长，可以看后台alert日志了解具体进展：

RMAN> restore database;

Starting restore at 26-APR-17
using channel ORA_DISK_1

8、开始recover database操作

应用归档日志恢复数据文件

恢复命令：

recover database

执行过程：

RMAN>  recover database;

RMAN>

看到有报错信息，需要将缺失的归档日志从云上的原始备份库copy到本地自己机房的oracle服务器上，或者直接恢复到SCN点13990495654上，这里因为是恢复到临时库，所以选择直接恢复到SCN的13990495654点上，命令为recover database until scn 13990495654;

执行恢复到SCN点：

RMAN> recover database until scn 14264134636;

Starting recover at 26-APR-17
using channel ORA_DISK_1

附带recovery过程报错处理：

报错信息：

db_recovery_file_dest_size of 15360 MB is0.21% used. This is a

user-specified limit on the amount of spacethat will be used by this

database for recovery-related files, anddoes not reflect the amount of

space available in the underlyingfilesystem or ASM diskgroup.

处理方案：

alter system set db_recovery_file_dest_size= 50g scope=both;

9、打开数据库

然后使用resetlogs打开数据库，成功了，这里需要使用resetlogs方式打开，否则会报错。

RMAN> alter database open resetlogs;

database opened

RMAN>
