将服务器192.168.182.133上的10g库PROD2迁移至服务器192.168.182.131上的11g数据库PROD4

1. Preparations
1.1 setup auxiliary instance
1.1.1 orapwd
on 131-源库服务器
cd $ORACLE_HOME/dbs
orapwd file=orapwPROD4 password=oracle

1.1.2 export ORACLE_SID=PROD4
on 131

1.1.3 mkdir
on 131
mkdir -p /u01/app/oracle/admin/PROD4/{a,b,c,u}dump
mkdir -p /u01/app/oracle/oradata/PROD4/

1.1.4 pfile
on 133-目标库服务器
cd $ORACLE_HOME/dbs
sqlplus / as sysdba
create pfile from spfile;

scp initPROD2.ora oelr5u8-1:/u01/app/oracle/product/11.2.0/db_1/dbs/initPROD4.ora

on 131
cd cd $ORACLE_HOME/dbs

改为符合辅助实例和11g数据库的要求

## for auxiliary instance
DB_FILE_NAME_CONVERT='PROD2','PROD4'
LOG_FILE_NAME_CONVERT='PROD2','PROD4'

1.1.5 startup nomount on auxiliary instance
on 131

export ORACLE_SID=PROD4
sqlplus / as sysdba
create spfile from pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initPROD4.ora';

1.1.6 setup listener and tnsnames
on 133
vi tnsnames.ora
add:
PROD4_oelr5u8-1=
(description=
(address=(protocol=tcp)(host=oelr5u8-1)(port=1521))
(connect_data=
(server=dedicated)
(service_name=PROD4)
)
)

on 131
vi listener.ora
add into sid_list_listener:
(sid_desc=
(global_dbname=PROD4)
(oracle_home=/u01/app/oracle/product/11.2.0/db_1)
(sid_name=PROD4
)

lsnrctl start

vi tnsnames.ora
PROD2_odd-oelr4u8 =
(description =
(address = (protocol = tcp)(host = odd-oelr4u8)(port = 1521))
(connect_data =
(server = dedicated)
(service_name = PROD2)
)
)

1.2 check target database's backup
on 133
ensure that archive log mode is on

rman target /
list backup of database;
note: cannot use backup as compressed backupset... errors will be reported when duplicating

2. duplicate

rman target sys/oracle@PROD2 auxiliary sys/oracle@PROD4_oelr5u8-1

Recovery Manager: Release 10.2.0.1.0 - Production on Sat Apr 5 15:37:35 2014

connected to target database: PROD2 (DBID=1490667694)
connected to auxiliary database: PROD4 (not mounted)

RMAN> duplicate target database to PROD4;
