Migrate uard to a single machine in RAC Environment

Environment Description:

Oracle Version: 11.2.0.3.0
Primary end:
For dual-node RAC, scan uses DNS resolution to run two instances (JSTDB & PAYDB)
Standby end:
Standalone Federation uard

1. Set the network environment;
Vi/etc/hosts
192.168.253.101 rac1.test.com rac1
192.168.253.102 rac2.test.com rac2
192.168.253.103 rac1-vip.test.com rac1-vip
192.168.253.104 rac2-vip.test.com rac2-vip
10.10.10.11 rac1-priv.test.com rac1-priv
Rac2-priv.test.com 10.10.10.12 rac2-priv
192.168.253.200 standby
Vi/etc/resolv. conf
Nameserver 192.168.253.100

Nslookup scan.test.com
Server: 192.168.253.100
Address: 192.168.253.100 #53
Name: scan.test.com
Address: 192.168.253.107
Name: scan.test.com
Address: 192.168.253.106
Name: scan.test.com
Address: 192.168.253.105

3. View and add standby logfile;
Set line 180 pages 1000
Col member for a50
Select * from v $ logfile order by GROUP #;
Alter system set standby_file_management = manual scope = both sid = '*';
Alter database add standby logfile thread 1 group 5' + DATA/jstdb/onlinelog/standby_redo1-1.log 'size 50 M;
Alter database add standby logfile thread 1 group 6' + DATA/jstdb/onlinelog/standby_redo1-2.log 'size 50 M;
Alter database add standby logfile thread 1 group 7' + DATA/jstdb/onlinelog/standby_redo1-3.log 'size 50 M;
Alter database add standby logfile thread 1 group 8' + DATA/jstdb/onlinelog/standby_redo1-4.log 'size 50 M;
Alter database add standby logfile thread 2 group 9' + DATA/jstdb/onlinelog/standby_redo2-1.log 'size 50 M;
Alter database add standby logfile thread 2 group 10' + DATA/jstdb/onlinelog/standby_redo2-2.log 'size 50 M;
Alter database add standby logfile thread 2 group 11' + DATA/jstdb/onlinelog/standby_redo2-3.log 'size 50 M;
Alter database add standby logfile thread 2 group 12 '+ DATA/jstdb/onlinelog/standby_redo2-4.log 'size 50 M;
Alter system set standby_file_management = auto scope = both sid = '*';

4. Collect information about the master database;
Set line 180 pages 1000
Col value for a90
Col name for a50
Select name, value from v $ parameter
Where name in ('db _ name ',
'Db _ unique_name ',
'Log _ archive_config ',
'Log _ archive_dest_1 ',
'Log _ archive_dest_2 ',
'Log _ archive_dest_state_1 ',
'Log _ archive_dest_state_2 ',
'Remote _ login_passwordfile ',
'Remote _ listener ',
'Log _ archive_format ',
'Log _ archive_max_processes ',
'Fal _ Server', 'fal _ client ',
'Db _ file_name_convert ',
'Log _ file_name_convert ',
'Standby _ file_management ');

5. Create an archive log directory for the local hard disk and an rman backup directory;
Mkdir-p/u01/arch/JSTDB
Chown-R oracle. oinstall/u01/arch/
Mkdir-p/u01/rman/JSTDB
Chown-R oracle. oinstall/u01/rman/

6. Modify the DG configuration of the master database;
Alter system set DB_UNIQUE_NAME = JSTDB scope = both sid = '*';
Alter system set LOG_ARCHIVE_CONFIG = 'dg _ CONFIG = (JSTDB, JSTDG1) 'scope = both sid = '*';
Alter system set LOG_ARCHIVE_DEST_1 = 'location = + FRA/JSTDB/ARCHIVELOG/VALID_FOR = (ALL_LOGFILES, ALL_ROLES) DB_UNIQUE_NAME = JSTDB 'scope = both sid = '*';
Alter system set LOG_ARCHIVE_DEST_2 = 'service = JSTDG1 lgwr async VALID_FOR = (ONLINE_LOGFILES, PRIMARY_ROLE) DB_UNIQUE_NAME = JSTDG1 'scope = both sid = '*';
Alter system set LOG_ARCHIVE_DEST_STATE_1 = ENABLE scope = both sid = '*';
Alter system set LOG_ARCHIVE_DEST_STATE_2 = ENABLE scope = both sid = '*';
Alter system set REMOTE_LOGIN_PASSWORDFILE = SHARED scope = spfile sid = '*';
Alter system set REMOTE_LISTENER = 'Scan .test.com: 1521 'scope = spfile sid = '*';
Alter system set LOG_ARCHIVE_MAX_PROCESSES = 8 SCOPE = both sid = '*';
Alter system set FAL_CLIENT = jstdb scope = both sid = '*';
Alter system set FAL_SERVER = JSTDG1 SCOPE = both sid = '*';
Alter system set db_file_name_convert = '/u01/app/oracle/oradata/JSTDG1/', '+ DATA/JSTDB/'scope = spfile sid = '*';
Alter system set log_file_name_convert = '/u01/app/oracle/oradata/JSTDG1/onlinelog/', '+ DATA/JSTDB/onlinelog /', '/u01/app/oracle/oradata/JSTDG1/onlinelog/', '+ FRA/JSTDB/onlinelog/', '/u01/arch/JSTDG1 /', '+ FRA/JSTDB/ARCHIVELOG/' SCOPE = spfile sid = '*';
Alter system set STANDBY_FILE_MANAGEMENT = auto scope = both sid = '*';

Modify the archivelog format
Alter system set log_archive_format = 'arch _ % r _ % t _ % s. arc' scope = spfile sid = '*';
Shutdown immediate
Startup

7. Create a pfile for the standby database;
Create pfile = '/u01/rman/initJSTDB. ora' from spfile;

8. Modify tns;
Cd $ ORACLE_HOME/network/admin
Vi 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.

JSTDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = scan.test.com) (PORT = 1521 ))
(LOAD_BALANCE = yes)
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = JSTDB)
)
)

JSTDB1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = rac1.test.com) (PORT = 1521 ))
(ADDRESS = (PROTOCOL = TCP) (HOST = rac1-vip.test.com) (PORT = 1521 ))
)
(CONNECT_DATA =
(SERVICE_NAME = JSTDB)
(INSTANCE_NAME = JSTDB1)
)
)

JSTDB2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = rac2.test.com) (PORT = 1521 ))
(ADDRESS = (PROTOCOL = TCP) (HOST = rac2-vip.test.com) (PORT = 1521 ))
)
(CONNECT_DATA =
(SERVICE_NAME = JSTDB)
(INSTANCE_NAME = JSTDB2)

)
)

JSTDG1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = standby) (PORT = 1521 ))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = JSTDG1)
)
)

PAYDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = scan.test.com) (PORT = 1521 ))
(LOAD_BALANCE = yes)
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PAYDB)
)
)

PAYDG1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = standby) (PORT = 1521 ))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PAYDB)
)
)

9. Add a listener to the slave database;

Cd $ ORACLE_HOME/network/admin
Vi listener. ora
# Listener. ora Network Configuration File:/u01/app/oracle/network/admin/listener. ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = standby) (PORT = 1521 ))
(ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1521 ))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = JSTDG1)
(ORACLE_HOME =/u01/app/oracle)
(SID_NAME = JSTDB)
)
(SID_DESC =
(GLOBAL_DBNAME = PAYDG1)
(ORACLE_HOME =/u01/app/oracle)
(SID_NAME = PAYDB)
)
)
ADR_BASE_LISTENER =/u01/app/oracle
Slave database restart listening service
Lsnrctl stop
Lsnrctl start

10. Generate the standby control file on node 1 of RAC;
Export ORACLE_SID = JSTDB1
Rman target/
Backup device type disk format'/u01/rman/ctl01.ctl 'current controlfile for standby;

Scp/u01/rman/ctl01.ctl standby:/u01/rman/

11. Create related directories in standby;
@ Root User
Mkdir-p/u01/rman/JSTDB
Chown-R oracle. oinstall/u01/rman/
Mkdir-p/u01/arch/JSTDG1
Chown-R oracle. oinstall/u01/arch/
@ Oracle user
Mkdir-p/u01/app/oracle/oradata/JSTDG1/datafile/
Mkdir-p/u01/app/oracle/oradata/JSTDG1/onlinelog
Mkdir-p/u01/app/oracle/admin/JSTDG1/adump

12. Copy the password file;

Orapwd file =/$ ORACLE_HOME/dbs/orapwJSTDB1 password = oracle force = y ignorecase = y
Scp/$ ORACLE_HOME/dbs/orapwJSTDB1 rac2:/$ ORACLE_HOME/dbs/orapwJSTDB2
Scp/$ ORACLE_HOME/dbs/orapwJSTDB1 standby:/u01/app/oracle/dbs/orapwJSTDB

13. Copy the parameter file to the slave database and modify the relevant content;
@ Master database
Scp/u01/rman/initJSTDB. ora standby:/u01/app/oracle/dbs/initJSTDB. ora
@ Slave Database
Vi/u01/app/oracle/dbs/initJSTDB. ora
*. Audit_file_dest = '/u01/app/oracle/admin/JSTDG1/adump'
*. Audit_trail = 'db'
*. Compatible = '11. 2.0.0.0'

*. Control_files = '/u01/app/oracle/oradata/JSTDG1/control01.ctl', '/u01/app/oracle/oradata/JSTDG1/control02.ctl ', '/u01/app/oracle/oradata/JSTDG1/control03.ctl'
*. Db_block_size = 8192
# *. Db_create_file_dest = '/u01/app/oracle/oradata /'
# *. Db_create_online_log_dest_1 = '/u01/app/oracle/oradata/onlinelog /'
*. Db_domain =''
*. Db_file_name_convert = '+ DATA/JSTDB/', '/u01/app/oracle/oradata/JSTDG1 /'
*. Db_name = 'jstdb'
*. Db_unique_name = 'jstdg1'
*. Db_recovery_file_dest =''
*. Fal_client = 'jstdg1'
*. Fal_server = 'jstdb'
*. Log_archive_config = 'dg _ CONFIG = (JSTDB, JSTDG1 )'
*. Log_archive_dest_1 = 'location =/u01/arch/JSTDG1/VALID_FOR = (ALL_LOGFILES, ALL_ROLES) DB_UNIQUE_NAME = JSTDG1'
*. Log_archive_dest_2 = 'service = jstdb lgwr async VALID_FOR = (ONLINE_LOGFILES, PRIMARY_ROLE) DB_UNIQUE_NAME = jstdb'
*. Log_archive_format = 'arch _ % r _ % t _ % s. arc'
*. Log_archive_dest_state_1 = 'enable'
*. Log_archive_dest_state_2 = 'enable'
*. Log_archive_max_processes = 8

*. Log_file_name_convert = '+ DATA/JSTDB/onlinelog/', '/u01/app/oracle/oradata/JSTDG1/onlinelog/', '+ FRA/JSTDB/onlinelog /', '/u01/app/oracle/oradata/JSTDG1/onlinelog/', '+ FRA/JSTDB/ARCHIVELOG/', '/u01/arch/JSTDG1 /'
*. Open_cursors = 300
*. Processses = 150
*. Remote_login_passwordfile = 'shared'
*. Standby_file_management = 'auto'
*. Undo_management = 'auto'
Undo_tablespace = 'undotbs1'

14. Start the slave database to the nomount state;
Export ORACLE_SID = JSTDB
Sqlplus/as sysdba
Startup nomount pfile = '/u01/app/oracle/dbs/initJSTDB. ora ';
Create spfile from pfile = '/u01/app/oracle/dbs/initJSTDB. ora ';

 

15. Restore the control file of the slave database;
Rman target/
Restore standby controlfile from '/u01/rman/ctl01.ctl ';

 

16. Collect RAC database information;

Col file_name for a70
Select file_name, file_id from dba_data_files;

FILE_NAME FILE_ID
--------------------------------------------------------------------------------
+ DATA/jstdb/datafile/system.259.9079385031
+ DATA/jstdb/datafile/sysaux.260.9079385092
+ DATA/jstdb/datafile/undotbs1.261.90790000153
+ DATA/jstdb/datafile/undotbs2.263.9079424254
+ DATA/jstdb/datafile/users.264.9079385275
4 rows selected.

17. Back up the full master database (only for insurance backup, not copy to standby );
Rman target/

Backup format'/u01/rman/JSTDB/fulldb _ % d _ % U' database include current controlfile plus archivelog delete input;
