oracle使用rman备份集恢复方式创建ADG

一、背景

系统：

主库：rhel 6.4 64bit

备库：rhel 6.4 64bit

 

内存：2G

[oracle@dgdb1 ~]$ free -m

total used free shared buffers cached

Mem: 1863 1176 686 0 13 896

-/+ buffers/cache: 266 1596

Swap: 2047 78 1969

 

ip分配：

主库：192.168.12.50 dgdb1

备库：192.168.12.51 dgdb2

 

主库已安装数据库软件，并建库。

备库已安装数据库软件，未建库。

 

二、配置监听

主库：

LISTENER=

(DESCRIPTION=

(ADDRESS_LIST=

(ADDRESS=(PROTOCOL=tcp)(HOST=dgdb1)(PORT=1521))

)

)

SID_LIST_LISTENER=

(SID_LIST=

(SID_DESC=

(GLOBAL_DBNAME=rmanpri)

(ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1)

(SID_NAME=rmanpri)

)

)

 

备库：

LISTENER=

(DESCRIPTION=

(ADDRESS_LIST=

(ADDRESS=(PROTOCOL=tcp)(HOST=dgdb2)(PORT=1521))

)

)

SID_LIST_LISTENER=

(SID_LIST=

(SID_DESC=

(GLOBAL_DBNAME=rmanstd)

(ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1)

(SID_NAME=rmanstd)

)

)

 

三、配置tns

主库：

RMANPRI=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=dgdb1)(PORT=1521))

(CONNECT_DATA=

(SERVICE_NAME=rmanpri)

)

)

 

RMANSTD=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=dgdb2)(PORT=1521))

(CONNECT_DATA=

(SERVICE_NAME=rmanstd)

)

)

 

备库：

RMANPRI=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=dgdb1)(PORT=1521))

(CONNECT_DATA=

(SERVICE_NAME=rmanpri)

)

)

 

RMANSTD=

(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=dgdb2)(PORT=1521))

(CONNECT_DATA=

(SERVICE_NAME=rmanstd)

)

)

 

四、主库开启归档模式，开启强制日志

SQL> alter database archivelog;

SQL> alter database force logging;

SQL> alter database open;

 

五、修改主备库pfile

主库参数文件（initrmanpri.ora)内容如下：

rmanpri.__db_cache_size=415236096

rmanpri.__java_pool_size=4194304

rmanpri.__large_pool_size=8388608

rmanpri.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment

rmanpri.__pga_aggregate_target=197132288

rmanpri.__sga_target=587202560

rmanpri.__shared_io_pool_size=0

rmanpri.__shared_pool_size=150994944

rmanpri.__streams_pool_size=0

*.audit_file_dest='/u01/app/oracle/admin/rmanpri/adump'

*.audit_trail='db'

*.compatible='11.2.0.4.0'

*.control_files='/u01/app/oracle/oradata/rmanpri/control01.ctl','/u01/app/oracle/fast_recovery_area/rmanpri/control02.ctl'

*.db_block_size=8192

*.db_domain=''

*.db_name='rmanpri'

*.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'

*.db_recovery_file_dest_size=4385144832

*.diagnostic_dest='/u01/app/oracle'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=rmanpriXDB)'

*.open_cursors=300

*.pga_aggregate_target=195035136

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=585105408

*.undo_tablespace='UNDOTBS1'

DB_UNIQUE_NAME=rmanpri

LOG_ARCHIVE_CONFIG='DG_CONFIG=(rmanpri,rmanstd)'

LOG_ARCHIVE_DEST_1='LOCATION=/oracle/archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=rmanpri'

LOG_ARCHIVE_DEST_2= 'SERVICE=rmanstd ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=rmanstd'

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

FAL_SERVER=rmanstd

DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/rmanstd','/u01/app/oracle/oradata/rmanpri'

LOG_FILE_NAME_CONVERT='/u01/app/oracle/oradata/rmanstd','/u01/app/oracle/oradata/rmanpri'

STANDBY_FILE_MANAGEMENT=AUTO

 

修改完成后，主库使用修改后的参数文件启动数据库，并创建spfile。

 

备库参数文件(initrmanstd.ora)内容如下：

[oracle@dgdb2 dbs]$ vi initrmanstd.ora

rmanpri.__db_cache_size=415236096

rmanpri.__java_pool_size=4194304

rmanpri.__large_pool_size=8388608

rmanpri.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment

rmanpri.__pga_aggregate_target=197132288

rmanpri.__sga_target=587202560

rmanpri.__shared_io_pool_size=0

rmanpri.__shared_pool_size=150994944

rmanpri.__streams_pool_size=0

*.audit_file_dest='/u01/app/oracle/admin/rmanstd/adump'

*.audit_trail='db'

*.compatible='11.2.0.4.0'

*.control_files='/u01/app/oracle/oradata/rmanstd/control01.ctl','/u01/app/oracle/fast_recovery_area/rmanstd/control02.ctl'

*.db_block_size=8192

*.db_domain=''

*.db_name='rmanpri'

*.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'

*.db_recovery_file_dest_size=4385144832

*.diagnostic_dest='/u01/app/oracle'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=rmanstdXDB)'

*.open_cursors=300

*.pga_aggregate_target=195035136

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=585105408

*.undo_tablespace='UNDOTBS1'

DB_UNIQUE_NAME=rmanstd

LOG_ARCHIVE_CONFIG='DG_CONFIG=(rmanstd,rmanpri)'

LOG_ARCHIVE_DEST_1='LOCATION=/oracle/archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=rmanstd'

LOG_ARCHIVE_DEST_2= 'SERVICE=rmanpri ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=rmanpri'

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

FAL_SERVER=rmanpri

DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/rmanpri','/u01/app/oracle/oradata/rmanstd'

LOG_FILE_NAME_CONVERT='/u01/app/oracle/oradata/rmanpri','/u01/app/oracle/oradata/rmanstd'

STANDBY_FILE_MANAGEMENT=AUTO

 

六、主库使用修改后的pfile启动，并且创建spfile，再用spfile启动。

SQL> shutdown immediate

SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initrmanpri.ora';

SQL> create spfile from pfile;

SQL> shutdown immediate

SQL> startup

 

七、备库创建目录

[root@dgdb2 ~]# mkdir -p /rmanbak

[root@dgdb2 ~]# mkdir -p /oracle/archive

[root@dgdb2 ~]# chown -R oracle.oinstall /rmanbak/

[root@dgdb2 ~]# chown -R oracle.oinstall /oracle/archive/

[oracle@dgdb2 dbs]$ mkdir -p /u01/app/oracle/admin/rmanstd/{a,dp}dump

[oracle@dgdb2 dbs]$ mkdir -p /u01/app/oracle/fast_recovery_area/rmanstd

[oracle@dgdb2 dbs]$ mkdir -p /u01/app/oracle/oradata/rmanstd

 

八、主库全备

run

{

allocate channel c1 type disk;

allocate channel c2 type disk;

allocate channel c3 type disk;

backup database format '/rmanbak/full_%d_%T_%s_%p';

sql 'alter system archive log current';

sql 'alter system archive log current';

sql 'alter system archive log current';

backup archivelog all format '/rmanbak/arch_%d_%T_%s_%p';

backup current controlfile for standby format '/rmanbak/ctl_bf';

release channel c1;

release channel c2;

release channel c3;

}

 

九、将密码文件、修改后的参数文件传送到备库

[oracle@dgdb1 dbs]$ scp initrmanpri.ora oracle@dgdb2:$ORACLE_HOME/dbs/initrmanstd.ora

[oracle@dgdb1 dbs]$ scp orapwrmanpri oracle@dgdb2:$ORACLE_HOME/dbs/orapwrmanstd

 

十、使用参数文件将备库启动到nomount状态

SQL> startup nomount pfile=‘$ORACLE_HOME/dbs/initrmanstd.ora’；

 

十一、登录rman恢复控制文件

RMAN> restore standby controlfile from '/rmanbak/ctl_bf';

 

Starting restore at 21-NOV-19

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=19 device type=DISK

 

channel ORA_DISK_1: restoring control file

channel ORA_DISK_1: restore complete, elapsed time: 00:00:02

output file name=/u01/app/oracle/oradata/rmanstd/control01.ctl

output file name=/u01/app/oracle/fast_recovery_area/rmanstd/control02.ctl

Finished restore at 21-NOV-19

 

十二、将备库启动到mount状态

RMAN> alter database mount;

 

database mounted

released channel: ORA_DISK_1

 

十三、将传送到备库的数据库备份以及归档日志备份注册到rman

RMAN> catalog start with '/rmanbak/';

 

searching for all files that match the pattern /rmanbak/

 

List of Files Unknown to the Database

=====================================

File Name: /rmanbak/ctl_bf

 

Do you really want to catalog the above files (enter YES or NO)? yes

cataloging files...

cataloging done

 

List of Cataloged Files

=======================

File Name: /rmanbak/ctl_bf

 

十四、检查数据库备份以及归档日志备份

检查数据库备份

RMAN> list backup;

十六、恢复数据库

RMAN> recover database;

 

Starting recover at 21-NOV-19

allocated channel: ORA_DISK_1

这是正常的，因为还没有23号归档日志。

 

十七、启动备库

RMAN> alter database open;

 

database opened

 

十八、主备库创建standby logfile

主库创建standby logfile

SQL> alter database add standby logfile '/u01/app/oracle/oradata/rmanpri/stdby01.log' size 50m;

Database altered.

 

SQL> alter database add standby logfile '/u01/app/oracle/oradata/rmanpri/stdby02.log' size 50m;

SQL> alter database add standby logfile '/u01/app/oracle/oradata/rmanpri/stdby03.log' size 50m;

Database altered.

 

SQL> alter database add standby logfile '/u01/app/oracle/oradata/rmanpri/stdby04.log' size 50m;

Database altered.

 

SQL> alter database recover managed standby database using current logfile disconnect from session;

 

Database altered.

 

十八、应用归档

SQL> alter database recover managed standby database using current logfile disconnect from session;

 

Database altered.

 

十九、检查是否搭建成功
