===修改主库为归档模式

SQL> archive log list
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。

SQL> shutdown immediate
SQL> startup mount
SQL> alter database archivelog;
SQL> archive log list;
SQL> select name , open_mode, log_mode,force_logging from gv$database;NAME    OPEN_MODE    LOG_MODE FOR

------------------------------------ ----------- ------------------------------
db_recovery_file_dest    string    +FRA
db_recovery_file_dest_size    big integer 5727M

===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/bol1arch' sid='bol1';
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/gridENABLE_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
[root@dg1 ~]# cat /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
bol=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.11)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.12)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME =bol)))orcl=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.16)(PORT = 1521))  (CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME =orcl)))

--主库ping备库

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。

--alter system set db_unique_name='bol'  scope=spfile sid='*';
alter system set log_archive_config='dg_config=(bol,orcl)'   scope=spfile sid='*';
alter system set log_archive_dest_1='location=+FRA valid_for=(all_logfiles,all_roles) db_unique_name=bol'  scope=spfile sid='*';

alter system set log_archive_format='%t_%s_%r.arch' scope=spfile sid='*';

--备库参数

10 错误及相关解决方法

 --1 --主库ping备库，发现主库ping不同备库

[oracle@rac1 ~]$ tnsping orcl

TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 13-FEB-2019 11:40:14

Copyright (c) 1997, 2013, Oracle. All rights reserved.

Used parameter files:

TNS-03505: Failed to resolve name

--修改主备库的 tnsnames.ora，并reload

--修改备库的tnsnames.ora

--2 ORA-00845: MEMORY_TARGET not supported on this system

SQL> startup nomount
ORA-00845: MEMORY_TARGET not supported on this system

---修改/dev/shm

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

[root@dg1 ~]# cat /etc/fstab | grep tmpfs
tmpfs /dev/shm tmpfs defaults,size=2G 0 0

SQL> startup nomount
ORA-16025: parameter LOG_ARCHIVE_DEST_1 contains repeated or conflicting attributes
ORA-16154: suspect attribute: LOCATION

--LOG_ARCHIVE_DEST_1 参数重复，去掉一个即可，完整的pfile可以参照上面，已经是修改过的，

--3 rman的时候

DBGSQL: TARGET> begin :fhdbi := dbms_rcvcat.getDbid; end;
DBGSQL: sqlcode = 6550
DBGSQL: B :fhdbi = 32767
RMAN-00571: ===========================================================

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;

参考：https://blog.csdn.net/tianlesoftware/article/details/6232292

--4 db不能打开到opne 状态

SQL> alter database open;
alter database open

查看错误日志并进行解决

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

SQL> set sqlprompt "primary>"
primary>SELECT PROCESS,THREAD#,SEQUENCE#,STATUS FROM V$MANAGED_STANDBY;

PROCESS THREAD# SEQUENCE# STATUS

ARCH 1 189 CLOSING

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;
