Oracle 11g RAC+单实例数据库构建DataGuard

Oracle 11g RAC+单实例数据库构建DataGuard

一、数据库及操作系统初始环境：

准备已经安装完毕可以正常运行的RAC数据库，以及一台安装完Oracle软件未创建数据库的。
RAC和单实例安装可以参考链接：
其中RAC做为DG的主库。

1.我的规划配置如下：

RAC 节点1：-IPIP
如下：
[grid@bysrac1 ~]$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6localhost6

[oracle@racdg ~]$ cat .bash_profile
ORACLE_BASE=/u01
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
ORACLE_SID=racdg
PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH:$HOME/bin
export PATH ORACLE_BASE ORACLE_HOME ORACLE_SID
alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'

2.RAC数据库中各文件位置--恢复到备库时转化文件名字用

SYS@bysrac1>archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +BYSASMDATA
Oldest online log sequence 156
Next log sequence to archive 157
Current log sequence 157
SYS@bysrac1>show parameter recovery
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string +BYSASMDG
db_recovery_file_dest_size big integer 4977M
recovery_parallelism integer 0
SYS@bysrac1>select db_unique_name,name from v$database;
DB_UNIQUE_NAME NAME
------------------------------ ---------
bysrac BYSRAC
SYS@bysrac1>select name from v$datafile;
NAME
----------------------------------------------------------------------------------------------------
+BYSASMDATA/bysrac/datafile/system.259.818615175
+BYSASMDATA/bysrac/datafile/sysaux.260.818615237
+BYSASMDATA/bysrac/datafile/undotbs1.261.818615291
+BYSASMDATA/bysrac/datafile/undotbs2.263.818615365
+BYSASMDATA/bysrac/datafile/users.264.818615419
+BYSASMDATA/bysrac/datafile/test1_undo.dbf
+BYSASMDATA/bysrac/datafile/test1.dbf
BYS@bysrac1>selectname,block_size*file_size_blks/1024/1024 as bytes_m from v$controlfile;
NAME BYTES_M
-------------------------------------------------- ----------

+BYSASMDG/bysrac/controlfile/current.256.818615127 17.6875
BYS@bysrac1>select group#,member from v$logfile;
GROUP# MEMBER
---------- --------------------------------------------------
1+BYSASMDATA/bysrac/onlinelog/group_1.257.818615137
1+BYSASMDG/bysrac/onlinelog/group_1.257.818615145
2+BYSASMDATA/bysrac/onlinelog/group_2.258.818615153
2+BYSASMDG/bysrac/onlinelog/group_2.258.818615163
3+BYSASMDATA/bysrac/onlinelog/group_3.265.818619941

4+BYSASMDG/bysrac/onlinelog/group_4.260.818619967

二、修改RAC中初始化参数 3.在RAC主库中修改初始化参数

SQL> alter system set standby_file_management=auto scope=spfile;
SQL> alter system set log_archive_config="DG_CONFIG=(bysrac,racdg)"scope=spfile;
SQL> alter system set log_archive_dest_2="SERVICE=racdg LGWRSYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)DB_UNIQUE_NAME=racdg" scope=spfile;

SQL> alter system set fal_server=racdg scope=spfile;
SQL> alter system set fal_client=bysrac;

SQL> alter system setdb_file_name_convert="+BYSASMDATA/bysrac/datafile/","/u01/oradata/racdg",'+BYSASMDATA/bysrac/tempfile/','/u01/oradata/racdg/' scope=spfile;
SQL> alter system set log_file_name_convert="+BYSASMDATA/bysrac/onlinelog/","/u01/oradata/racdg"，'+BYSASMDG/bysrac/onlinelog/','/u01/oradata/racdg/' scope=spfile;
