11g oracle database refresh or clone to same name

For 11g databases you need to create a temporary listener with a different port on the target server or else it will show blocked status when database is started at nomount

Source and Target :

test_old =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.120.1.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test)
    )
  )
 
test_new =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.120.1.2)(PORT = 1525))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test)
    )
  )


Source:

create pfile from spfile;

alter user sys identified by "password" account unlock;

orapwd file=orapwtest password=password entries=5

scp  inittest.ora oracle@10.120.1.2:/opt/app/oracle/product/11.2.0/11.2.0.4/dbs/inittest.ora

scp  orapwtest oracle@10.120.1.2:/opt/app/oracle/product/11.2.0/11.2.0.4/dbs/orapwtest




Target:

Modify pfile

*.LOG_ARCHIVE_DEST_1='LOCATION=+REDO'
*.db_create_file_dest='+DATA'
*.db_create_online_log_dest_1='+REDO'
*.control_files='+DATA/test/controlfile/control01.ctl','+REDO/test/controlfile/control02.ctl'
*.audit_file_dest='/opt/app/oracle/admin/test/adump'
*.diagnostic_dest='/opt/app/oracle'

create directories as per pfile

mkdir -p /opt/app/oracle/admin/test/adump



 Target:

 startup nomount


 Source :
 
 rman target sys/password@test_old auxiliary sys/password@test_new


 duplicate target database to test from active database;
