set up a standby quickly by duplicate.
1.Create an Oracle Password File for the Auxiliary Instance
Password of user sys must be the same as primary side,so i copy the password file from primary,otherwise,you will get an error like:
ORA-16191: Primarylog shipping client not logged on standby
2.Ensure Oracle Net Connectivity to the Auxiliary Instance
dramaticly configure linster on standby(Auxiliary) side like:.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = O02DMS3)
(ORACLE_HOME = /dms01/app/oracle)
(GLOBAL_NAME = O02DMS3)
)
)
verify the connection from primary to standby.
example:sqlplus
sys/123@O02DMS3DR as sysdba
3.Create an Initialization Parameter File for the Auxiliary Instance
*.compatible='10.2.0.2.0'
*.control_files='/dms01/app/dump/controldr.ctl'
*.db_name='O02DMS3'
LOG_FILE_NAME_CONVERT=('+DG01/dms','/dms01/app/data/O02DMS3')
4.Start the Auxiliary Instance with the server parameter file
create spfile from pfile;startup force nomount
5.backup database and controlfile on primary sid by rman ,and then copy all those to standby on the same directory.
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/dms01/app/dump/rman/controldr.ctl';
6.Creating a Duplicate Database
rman TARGET/ AUXILIARY
SYS/123@O02DMS3DRRUN
{ SET NEWNAME FOR DATAFILE 1 TO '/dms01/app/data/O02DMS3/system01.dbf';
SET NEWNAME FOR DATAFILE 2 TO '/dms01/app/data/O02DMS3/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 3 TO '/dms01/app/data/O02DMS3/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 4 TO '/dms01/app/data/O02DMS3/users01.dbf';
SET NEWNAME FOR DATAFILE 5 TO '/dms01/app/data/O02DMS3/undotbs02.dbf';
DUPLICATE TARGET DATABASE FOR STANDBY NOFILENAMECHECK;

RMAN> exit
7.verify the role on both side.
standby:
SQL> select INST_ID,database_role from gv$database;
INST_ID DATABASE_ROLE
---------- ----------------
1 PHYSICAL STANDBY
PRIMARY:
SQL> select INST_ID,database_role from gv$database;
INST_ID DATABASE_ROLE

8.setting Parameters
primary side:
alter system set log_archive_config='DG_CONFIG=(DMS,O02DMS3DR)' scope=both sid='*';
alter system set LOG_ARCHIVE_DEST_2='SERVICE=O02DMS3DR VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=O02DMS3 LGWR ASYNC' scope=both sid='*';
standby side:
alter system set log_archive_config='DG_CONFIG=(DMS,O02DMS3DR)' scope=both sid='*';--don't miss it ,otherwise it will raise an error like:
ORA-16047: DGID mismatch between destination setting and standby
9.startup mrp and active log transport service.
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
perform. it on standby.
keep an eye on alert logfile.
alter system set log_archive_dest_state_2=defer;
alter system set log_archive_dest_state_2=enable;
col DEST_NAME for a30;
set linesize 200;
select DEST_NAME,STATUS,PROTECTION_MODE,ERROR from V$ARCHIVE_DEST_STATUS;
perform. it on primary.
