Create Standby database using Rman Duplicate Database from active database

Create Standby database using Rman Duplicate Database from active database

1. Configure or install oracle binary oracle_home in target system
2. Configure tns entries in both node(target and source). TNS entry should be pin-gable from source and target system
3. Create password file in target system using orapw utility. password should be same in source and target database
4. Start the target database in nomont point using temporary pfile
 
    $sqlplus / as sysdba

    sqlplus>startup nomount pfile=temppfile.ora

-bash-4.4$ cat temppfile.ora
db_name                         = ERPSBY
compatible                      = 12.1.0
control_files                   = '/erpsby_data1/oradata/control01.ctl','/erpsby_data1/oradata/control02.ctl'
*.db_create_file_dest='/erpsby_data1/oradata'
*.DB_CREATE_ONLINE_LOG_DEST_1='/erpsby_data1/oradata'
*.DB_CREATE_ONLINE_LOG_DEST_2='/erpsby_data1/oradata'
*.memory_target=10G
*.remote_login_passwordfile='exclusive'
DB_FILES=2000

5. Connect to auxilary database

rman target sys/manager@source-tns  AUXILIARY sys/manager@target-tns

run {
allocate channel prmy1 type disk;
allocate channel prmy2 type disk;
allocate channel prmy3 type disk;
allocate channel prmy4 type disk;
allocate auxiliary channel stby type disk;
