切换归档，将所有节点都必须处于 mount 状态。 在其中一个节点修改模式，然后在其他节点正常启动即可。

===2 个节点的归档都指向了+FRA 这个磁盘组。 也可以指向其他的磁盘组或者本地的位置，如：

SQL> alter system set log_archive_dest_1='location=/u01/bol2arch' sid='bol2';
3 主备库添加 standby Redo log 文件
RAC 每个 Redo Thread 都需要创建对应的 Standby Redo Log。 创建原则和单实例一样，包括日志 文件大小相等，日志组数量要多 1 组。

4 配置主备库的监听
用 net manager 工具，在备库创建一个监听。 也可以手动的修改 listener.ora 文件
--对于 RAC 环境:
在 grid 用户的 listener.ora 文件中加入如下内容：
[grid@rac1 ~]$ cd /u01/app/11.2.0/grid/network/admin/
[grid@rac1 admin]$ cat listener.ora
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
[grid@rac1 admin]$ vim listener.ora
[grid@rac1 admin]$ cat listener.ora
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = bol)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = bol1)
)
) LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER))
) ADR_BASE_LISTENER = /u01/app/grid ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent LISTENER_SCAN1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER_SCAN1))
) ADR_BASE_LISTENER_SCAN1 = /u01/app/grid 节点 2，对应修改即可
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = bol)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = bol2)
)
)
--这里写的 Oracle 用户的 ORACLE_HOME
然后重启监听
注意在 oracle 11gR2 的 RAC 环境下，监听是在 grid 用户下配置的。所以这里可以用 grid 用户连接并修改。 最后重启监听
对于单实例，直接在 listener.ora 里添加
[oracle@dg1 oracle]$ cd /u01/app/oracle/product/11.2.0/db_1/network/admin/
[oracle@dg1 admin]$ vim listener.ora
[oracle@dg1 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools. SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcl)
)
) LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dg1)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
) ADR_BASE_LISTENER = /u01/app/oracle
配置主备库的 Net Server： tnsnames.ora
节点1，节点2，单实例 的 tnsnames.ora 文件是一致的，添加以下内容---其实也可以不一致
[oracle@rac1 admin]$ vim tnsnames.ora
[oracle@rac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools. BOL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = scanip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bol)
)
) bol1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.13)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bol1)
)
) bol2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.14)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bol2)
)
) orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.16)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
) [grid@rac1 admin]$ lsnrctl reload
[oracle@dg1 admin]$ echo $ORACLE_HOME [oracle@dg1 admin]$ source /home/oracle/.bash_profile
[oracle@dg1 admin]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/db_1
[oracle@dg1 admin]$ lsnrctl start
--备库 /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

5 备库创建相应的目录
[oracle@dg1 admin]$ mkdir -p /u01/app/oracle/fast_recovery_area/orcl
mkdir -p /u01/app/oracle/oradata/orcl/data
mkdir -p /u01/app/oracle/oradata/orcl/tempfile

[oracle@dg1 admin]$ mkdir -p /u01/app/oracle/admin/orcl/tempfile
[oracle@dg1 oracle]$ mkdir -p /u01/app/oracle/archive
6 修改RAC参数，并生成pfile与密码文件一起传输到备库
复制rac1的密码文件传到备库
[oracle@rac1 dbs]$ scp orapwbol1 oracle@10.*.16:/u01/app/oracle/product/11.2.0/db_1/dbs/orapworcl
创建修改主备库的参数文件
--主库参数
db_file_name_convert 和 log_file_name_convert 仅当数据库被 standby 时才会生效，这里配置，是 为切换做准备。 log_file_name_convert 指的是 online redo log。
在 Oracle 11g 已经废除了 fal_client 参数。
RAC 的 spfile 是放在共享设备上的，所以如果想创建，就需要先创建一份 pfile 到本地，在修改，如果不想这么折腾，就直接使用 SQL 语句修改：
1）使用 ASM 作为存储时，datafile 和 tempfile 是分别放在两个目录下的，所以在Standby 上也单独创建一个tempdata 目录。并在db_file_name_convert 中作相应的设置。
2）在使用ASM 的RAC中，注意不要改变db_unique_name 的参数值；因为ASM 存放文件的规则，是按照+diskgroup_name/data_unique_name/file/tag_name.file_member.incarnation 这样一个规则存放的，
但是第二项database_unique_name 并不是db_name;如果改变了db_unique_name,则之后创建的数据文件会放在新的目录下，会导致db_file_name_convert 的失效，这一点需要特别注意。
3）如果RAC中使用db_create_online_log_dest_n 系列参数，要相应调整stangby 上的log_file_name_convert 参数。

简单来说就是 MEMORY_MAX_TARGET 的设置不能超过 /dev/shm 的大小

1）如果使用的是非catalog，在rman 连接时，加上nocatalog关键字，如
[oracle@dg1 dbs]$ rman target sys/*@bol auxiliary sys/*@orcl nocatalog
2） 在执行duplicate的时候，如果源库和目标库目录相同，那么在duplicate 时，需要加上nofilenamecheck，如下
RMAN> duplicate target database forstandby from active database dorecover nofilenamecheck;

在主库找到对应的日志文件并cp到备库
ASMCMD> cp +FRA/bol/arch/150_1_990861401.log /u01/app/oracle
copying +FRA/bol/arch/150_1_990861401.log -> /u01/app/oracle/150_1_990861401.log
[oracle@rac1 oracle]$ scp 150_1_990861401.log oracle@10.15.7.16:/u01/app/oracle/archive/.
在备库上执行
SQL> alter database register physical logfile '/u01/app/oracle/archive/150_1_990861401.log';
Database altered.
--5 主备库不同步，日志也并没有报错
最后完成，发现主库的操作米有同步过去
SQL> set sqlprompt "primary>"
primary>SELECT PROCESS,THREAD#,SEQUENCE#,STATUS FROM V$MANAGED_STANDBY;
PROCESS THREAD# SEQUENCE# STATUS
--------- ---------- ---------- ------------
ARCH 1 185 CLOSING
ARCH 1 186 CLOSING
ARCH 0 0 CONNECTED
ARCH 1 187 CLOSING
由于前面修改了主库的spfile的一些参数，要重启db才能生效
[grid@rac1 ~]$ srvctl stop instance -o immediate -d bol -i bol1
[grid@rac1 ~]$ srvctl status database -d bol
Instance bol1 is not running on node rac1
Instance bol2 is not running on node rac2
[grid@rac1 ~]$ srvctl start instance -d bol -i bol1
重启过后，主备dg自动同步

日常运维管理
SQL> archive log list;
主库与备库当前使用的日志编号相同
停主库的监听程序
lsnrctl stop
关闭主数据库
SQL> shutdown immediate;
查看备库的开启模式
SQL> select open_mode from v$database;
关闭备数据库的归档应用程序
SQL> alter database recover managed standby database cancel;
主库切换归档日志
SQL> alter system archive log current;
查看备库是否有新应用过来的日志
SQL> select sequence#,applied from v$archived_log;
备库上开启归档日志应用进程
SQL> alter database recover managed standby database disconnect from session;
检查主备库是否存在GAP
主库检查current sequence#
SQL> select thread#,sequence#,status from v$log;
SQL> select process,sequence#,status from v$managed_standby;
SQL> SELECT PROCESS,THREAD#,SEQUENCE#,STATUS FROM V$MANAGED_STANDBY;
检查是否存在GAP
SQL> SELECT THREAD#,LOW_SEQUENCE#,HIGH_SEQUENCE# FROM V$ARCHIVE_GAP;---由此可判断主备库无GAP，可进行正常switchover切换
SELECT DATABASE_ROLE, DB_UNIQUE_NAME INSTANCE, OPEN_MODE,PROTECTION_MODE, PROTECTION_LEVEL, SWITCHOVER_STATUS FROM V$DATABASE;
