2、安装standby端的RAC环境
(略.. 只安装GI和数据库软件、配置监听和ASM实例、diskgroup)
|
[root@11gracdg1 ~]# crsctl status resource -t ------------------------------------------------------------------------------ NAME TARGET STATE SERVER STATE_DETAILS ------------------------------------------------------------------------------ Local Resources ------------------------------------------------------------------------------ ora.CRSDG.dg ONLINE ONLINE 11gracdg1 ONLINE ONLINE 11gracdg2 ora.DATADG.dg ONLINE ONLINE 11gracdg1 ONLINE ONLINE 11gracdg2 ora.LISTENER.lsnr ONLINE ONLINE 11gracdg1 ONLINE ONLINE 11gracdg2 ora.asm ONLINE ONLINE 11gracdg1 Started ONLINE ONLINE 11gracdg2 Started ora.gsd OFFLINE OFFLINE 11gracdg1 OFFLINE OFFLINE 11gracdg2 ora.net1.network ONLINE ONLINE 11gracdg1 ONLINE ONLINE 11gracdg2 ora.ons ONLINE ONLINE 11gracdg1 ONLINE ONLINE 11gracdg2 ora.registry.acfs ONLINE ONLINE 11gracdg1 ONLINE ONLINE 11gracdg2 ------------------------------------------------------------------------------ Cluster Resources ------------------------------------------------------------------------------ ora.11gracdg1.vip 1 ONLINE ONLINE 11gracdg1 ora.11gracdg2.vip 1 ONLINE ONLINE 11gracdg2 ora.LISTENER_SCAN1.lsnr 1 ONLINE ONLINE 11gracdg1 ora.cvu 1 ONLINE ONLINE 11gracdg1 ora.oc4j 1 ONLINE ONLINE 11gracdg1 ora.scan1.vip 1 ONLINE ONLINE 11gracdg1 [root@11gracdg1 ~]# |
3、配置primary端的静态监听及tnsnames.ora
--节点1 grid用户下的的listener.ora:
添加以下内容:
|
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = racdb_DGMGRL) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME = racdb1) ) ) |
--节点2 grid用户下的listener.ora:
添加以下内容:
|
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = racdb_DGMGRL) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME = racdb2) ) ) |
----重启监听：
Grid$ srvctl stop listener -n 11grac1
Grid$ srvctl stop listener -n 11grac2
Grid$ srvctl start listener -n 11grac1
Grid$ srvctl start listener -n 11grac2
注意:
1. GLOBAL_DBNAME的命名规则为DB_UNIQUE_NAME_DGMGRL
2. 配置GLOBAL_DBNAME是为了后面使用dg broker进行管理，如果不配置GLOBAL_DBNAME的静态注册，在使用dg broker进行switchover切换时，会提示无法解析TNS的错误。
--节点1和节点2 的oracle用户下的的tnsnames.ora:
添加以下内容:
|
RACDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac1-vip.oracle.com)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdb_DGMGRL) ) )
RACDB1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac1-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdb_DGMGRL) (INSTANCE_NAME = racdb1) ) )
RACDB2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdb_DGMGRL) (INSTANCE_NAME = racdb2) ) )
RACDBDG = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg1-vip.oracle.com)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdbdg_DGMGRL) ) )
RACDBDG1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg1-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdbdg_DGMGRL) (INSTANCE_NAME = racdbdg1) ) )
RACDBDG2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdbdg_DGMGRL) (INSTANCE_NAME = racdbdg2) ) ) |
4、primary端修改数据库参数,将数据库置于归档模式和force logging
|
alter system set log_archive_config='dg_config=(racdb,racdbdg)' scope=spfile sid='*'; alter system set log_archive_dest_1='LOCATION=+data VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=racdb' scope=spfile sid='*'; alter system set log_archive_dest_2='SERVICE=racdbdg LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=racdbdg' scope=spfile sid='*'; alter system set log_archive_format = '%t_%s_%r.arc' scope=spfile sid='*'; alter system set remote_login_passwordfile=EXCLUSIVE scope=spfile sid='*';
alter system set standby_file_management=auto scope=spfile sid='*'; alter system set db_file_name_convert='+datadg','+data' scope=spfile sid='*'; alter system set log_file_name_convert='+datadg','+data' scope=spfile sid='*';
|
|
$ srvctl stop database -d racdb -o immediate
alter database archivelog; alter database open; alter database force logging; shutdown immediate
$ srvctl start database -d racdb |
5、配置standby端的静态注册和tnsnames.ora
--节点1 grid用户的listener.ora:
|
SID_LIST_LISTENER = (SID_DESC = (GLOBAL_DBNAME = racdbdg_DGMGRL) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME = racdbdg1) ) |
--节点2 grid用户的listener.ora:
添加以下内容:
|
SID_LIST_LISTENER = (SID_DESC = (GLOBAL_DBNAME = racdbdg_DGMGRL) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME = racdbdg2) ) |
--节点1和节点2 的oracle用户下的的tnsnames.ora:
添加以下内容:
|
RACDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac1-vip.oracle.com)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdb_DGMGRL) ) )
RACDB1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac1-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdb_DGMGRL) (INSTANCE_NAME = racdb1) ) )
RACDB2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11grac2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdb_DGMGRL) (INSTANCE_NAME = racdb2) ) )
RACDBDG = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg1-vip.oracle.com)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdbdg_DGMGRL) ) )
RACDBDG1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg1-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdbdg_DGMGRL) (INSTANCE_NAME = racdbdg1) ) )
RACDBDG2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 11gracdg2-vip.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = racdbdg_DGMGRL) (INSTANCE_NAME = racdbdg2) ) ) |
6、配置primary端及standby端的hosts解析
|
### 11g rac ### 192.168.56.120 11grac1.oracle.com 11grac1 10.0.0.5 11grac1-priv1.oracle.com 11grac1-priv1 10.0.0.7 11grac1-priv2.oracle.com 11grac1-priv2 192.168.56.121 11grac1-vip.oracle.com 11grac1-vip

192.168.56.129 racdg-scan.oracle.com racdg-scan |
7、primary端生成pfile,将生成的pfile和密码复制至standby端
SQL> create pfile='/tmp/pfile.ora' from spfile;
$ scp /tmp/pfile.ora 11gracdg1:$ORACLE_HOME/dbs
cd $ORACLE_HOME/dbs
$ scp orapwracdb1 11gracdg1:$ORACLE_HOME/dbs
8、在primary库做RMAN全备及备份控制文件
backup full database format='/u01/software/for_standby_%u%p%s.RMN' include current controlfile for standby;
SQL> alter system archive log current;
SQL> alter system archive log current;
SQL> alter system archive log current;
9、将primary库生成的RMAN备份集上传至standby库的相同目录
$ scp for_standby_*.RMN 11gracdg1:/u01/software
10、primary端创建standby logfile
---- 在primary端创建standby logfile(每组thread都需要):
11、修改standby端的pfile文件和密码文件,并启动至nomount状态
修改之后的参数：
|
[oracle@11gracdg1 dbs]$ more initracdbdg1.ora *.audit_file_dest='/u01/app/oracle/admin/racdb/adump' *.audit_trail='db' *.cluster_database=true *.compatible='11.2.0.4.0' *.control_files='+DATAdg/racdb/controlfile/control01.ctl' *.db_block_size=8192 *.db_create_file_dest='+DATADG' *.db_domain='' *.db_file_name_convert='+data','+datadg' *.db_name='racdb' *.db_unique_name='racdbdg' *.diagnostic_dest='/u01/app/oracle' racdbdg1.instance_number=1 racdbdg2.instance_number=2 *.log_archive_config='dg_config=(racdb,racdbdg)' *.log_archive_dest_1='LOCATION=+datadg VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=racdbdg' *.log_archive_dest_2='SERVICE=racdb LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=racdb' *.log_archive_format='%t_%s_%r.arc' *.log_file_name_convert='+data','+datadg' *.open_cursors=300 *.pga_aggregate_target=209715200 *.processes=300 *.remote_listener='racdg-scan.oracle.com:1521' *.remote_login_passwordfile='EXCLUSIVE' *.sessions=335 *.sga_target=1073741824 *.standby_file_management='AUTO' racdbdg1.thread=1 racdbdg2.thread=2 racdbdg1.undo_tablespace='UNDOTBS1' racdbdg2.undo_tablespace='UNDOTBS2' [oracle@11gracdg1 dbs]$ |
SQL> startup nomount;
ORACLE instance started.

Fixed Size 1262140 bytes
Variable Size 322964932 bytes
Database Buffers 92274688 bytes
Redo Buffers 2928640 bytes
standby端的所有节点都启动至nomount状态：
|
Standby端的第一个节点复制 pfile和密码文件 至其它节点，并启动至nomount: [oracle@11gracdg1 dbs]$ scp initracdbdg1.ora 192.168.56.132:/u01/app/oracle/product/11.2.0.4/db_home/dbs/ initracdbdg1.ora 100% 1185 1.2KB/s 00:00 [oracle@11gracdg1 dbs]$ scp orapwracdbdg1 192.168.56.132:/u01/app/oracle/product/11.2.0.4/db_home/dbs/ orapwracdbdg1 100% 1536 1.5KB/s 00:00 [oracle@11gracdg1 dbs]$ |
12、配置及测试主备库的监听及TNS
|
sqlplus sys/welcome1@racdb1 as sysdba sqlplus sys/welcome1@racdb2 as sysdba sqlplus sys/welcome1@racdb as sysdba sqlplus sys/welcome1@racdbdg1 as sysdba sqlplus sys/welcome1@racdbdg2 as sysdba sqlplus sys/welcome1@racdbdg as sysdba |
13、将主库的文件复制至备库
在源端操作:
rman target / auxiliary sys/welcome1@racdbdg1
duplicate target database for standby nofilenamecheck;
14、启动standby库(先检测是否能应用归档日志)
startup nomount;
alter database mount standby database;
alter database recover managed standby database disconnect from session;
如果能应用归档日志,说明配置成功.

15、standby端创建standby logfile
---- 在standby端创建standby logfile(每组thread都需要):
alter system set standby_file_management=manual sid='*';
alter database recover managed standby database cancel;
alter database add standby logfile thread 1 group 7 '+datadg/racdbdg/onlinelog/standby_07.log' size 50m;
alter database add standby logfile thread 1 group 8 '+datadg/racdbdg/onlinelog/standby_08.log' size 50m;
alter database add standby logfile thread 1 group 9 '+datadg/racdbdg/onlinelog/standby_09.log' size 50m;
alter database add standby logfile thread 1 group 10 '+datadg/racdbdg/onlinelog/standby_10.log' size 50m;
alter database add standby logfile thread 2 group 11 '+datadg/racdbdg/onlinelog/standby_11.log' size 50m;
alter database add standby logfile thread 2 group 12 '+datadg/racdbdg/onlinelog/standby_12.log' size 50m;
alter database add standby logfile thread 2 group 13 '+datadg/racdbdg/onlinelog/standby_13.log' size 50m;
alter database add standby logfile thread 2 group 14 '+datadg/racdbdg/onlinelog/standby_14.log' size 50m;
alter system set standby_file_management=auto sid='*';
16、注册standby 端的database 资源
--生成新的spfile文件:
SQL> create spfile='+datadg/racdbdg/spfileracdbdg.ora' from pfile='/u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/initracdbdg1.ora';
File created.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>
--修改pfile文件:
[oracle@10gracdg1 dbs]$ mv initracdbdg1.ora initracdbdg1.ora_bak
[oracle@10gracdg1 dbs]$ vi initracdbdg1.ora
添加如下内容:
spfile='+datadg/racdbdg/spfileracdbdg.ora'
--添加资源:
注意:
在注册资源时，数据库名必须设置为db_unique_name, 而不能设置成db_name, 否则 在dgmgrl命令行中用switchover to standby时，报CRS 不允许的错误，导致无法正常切换。
