1, Environment Introduction
| ip | hostname | sid | db_name | db_unique_name | net service name |
|---|---|---|---|---|---|
| 192.168.56.118 | oraclep | yunhaip | yunhaip | yunhaip | yunhaip |
| 192.168.56.117 | oracles | yunhaip | yunhaip | yunhais | yunhais |
2, modify the hostname
hostnamectl set-hostname oraclep
3, db deployment
Owner: Create a library from: Do not create a database
that is not dbca that step, network and infrastructure environment is still needed
4, the main library open archives and to set a mandatory log force logging
SQL> shutdown immediate
Stop database operations
startup mount
State started to mount
alter database archivelog;
Open archives
alter database force logging;
Forced log, i.e., all operations for the database are generated log information, and writes the information to the online redo log file.
alter database open;
Open the database
archive log list;
To get data archiving mode
select force_logging from v$database;
Are you sure the log is forced
5, the main library to add standby redo log
select member from v$logfile;
View standby redo and redo
select * from v$log;
Check redo case
alter database add standby logfile group 21 '/u01/app/oradata/yunhaip/standby21.log' size 50M;
alter database add standby logfile group 22 '/u01/app/oradata/yunhaip/standby22.log' size 50M;
alter database add standby logfile group 23 '/u01/app/oradata/yunhaip/standby23.log' size 50M;
alter database add standby logfile group 24 '/u01/app/oradata/yunhaip/standby24.log' size 50M;By a group of standby redo 50M in size, where the group numbers shall not be repeated and online redo, formal environment need to adjust the file size
6, modify the configuration file
6.1, the main library pfile created in order to make changes
SQL>create pfile from spfile;
SQL> host
[oracle@oraclep ~]$ cd $ORACLE_HOME/dbs
[oracle@oraclep dbs]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dbs
cat >> /u01/app/oracle/product/11.2.0/db_1/dbs/inityunhaip.ora << "EOF"
*.db_unique_name='yunhaip'
*.fal_server='yunhais'
*.log_archive_config='dg_config=(yunhaip,yunhais)'
*.log_archive_dest_1='location=use_db_recovery_file_dest valid_for=(all_logfiles, all_roles) db_unique_name=yunhaip'
*.log_archive_dest_2='service=yunhais lgwr async valid_for=(online_logfile,primary_role) db_unique_name=yunhais'
*.log_archive_dest_state_1=ENABLE
*.log_archive_dest_state_2=ENABLE
*.standby_file_management='AUTO'
*.db_file_name_convert='/u01/app/oradata/yunhaip','/u01/app/oradata/yunhaip'
*.log_file_name_convert='/u01/app/oradata/yunhaip','/u01/app/oradata/yunhaip'
EOF
6.2, the master copy of the library from the library to pfile, and the following modifications:
[oracle@oraclep dbs]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dbs
[oracle@oraclep dbs]$ scp inityunhaip.ora
192.168.56.117:/u01/app/oracle/product/11.2.0/db_1/dbs/cat >> /u01/app/oracle/product/11.2.0/db_1/dbs/inityunhaip.ora << "EOF"
*.db_unique_name='yunhais'
*.fal_server='yunhaip'
*.log_archive_config='dg_config=(yunhaip,yunhais)'
*.log_archive_dest_1='location=use_db_recovery_file_dest valid_for=(all_logfiles, all_roles) db_unique_name=yunhais'
*.log_archive_dest_2='service=yunhaip lgwr async valid_for=(online_logfile,primary_role) db_unique_name=yunhaip'
*.log_archive_dest_state_1=ENABLE
*.log_archive_dest_state_2=ENABLE
*.standby_file_management='AUTO'
*.db_file_name_convert='/u01/app/oradata/yunhaip','/u01/app/oradata/yunhaip'
*.log_file_name_convert='/u01/app/oradata/yunhaip','/u01/app/oradata/yunhaip'
EOF
6.3 Description:
dg_config = (yunhaip, yunhais) except where the main information from the other can be reversed
6.4, create a new master database spfile file, and restart the main library
SQL> shutdown immediate
SQL> create spfile from pfile;
SQL> startup
SQL> ALTER USER SYS IDENTIFIED BY sys;Modify the sys password for future use rman connection
6.5, the main library to copy the password file to the standby database
scp orapwyunhaip 192.168.56.117:/u01/app/oracle/product/11.2.0/db_1/dbs/
7, create the relevant directory from the library
strings spfileyunhaip.ora
Get directory, I have observed that the main library
mkdir -p /u01/app/oracle
mkdir -p /u01/app/admin/yunhaip/{a,b,c,d,u}dump
mkdir -p /u01/app/oradata/yunhaip/
mkdir -p /u01/app/fast_recovery_area/yunhaip/
8, create a tnsnames.ora, from the same master to
cat >> /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora << "EOF"
yunhaip =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.118)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = yunhaip)
)
)yunhais =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.117)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = yunhais)
)
)
EOF
9, listener.ora modify the backup library
cat >> /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora << "EOF"
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = yunhais)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = yunhaip)
)
)EOF
原因如下：
