Duplicating Oracle 11g Database using Active database option


Source DB
===========
Host Name=oradbsrvr1
DB Name=racdb
Oracle Version=11.2.0.1.0
Oracle Home=/u01/oracle/product/11.2.0/db
dbfiles_loc=/u01/oradata/racdb

Target DB
===========
Host Name= oradbsrvr2
DB Name=testdb
Oracle Version=11.2.0.1.0
Oracle Home=/u01/oracle/product/11.2.0/db1
dbfiles_loc=/u02/oradata/testdb

Step1: Creating Init.ora File on target system
=================================================
*.audit_file_dest='/u01/oracle/oraclebase/admin/testdb/adump'
*.compatible='11.2.0'
*.control_files='/u02/oradata/testdb/control01.ctl'
*.db_block_size=8192
*.db_create_file_dest='/u02/oradata'
*.db_domain=''
*.db_file_multiblock_read_count=16
*.db_name='TESTDB'#Modified by RMAN duplicate
*.db_recovery_file_dest_size=2147483648
*.db_recovery_file_dest='/u02/oradata'
*.db_unique_name='TESTDB'#Modified by RMAN duplicate
*.diagnostic_dest='/u01/oracle/oraclebase'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=testdbXDB)'
*.java_pool_size=134217728
*.job_queue_processes=10
*.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=oradbsrvr2)(PORT=1521))'
*.log_buffer=11485660
*.open_cursors=300
*.pga_aggregate_target=298844160
*.processes=600
*.remote_login_passwordfile='EXCLUSIVE'
*.session_cached_cursors=300
*.sga_target=897581056
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS1'
*.db_file_name_convert='/u01/oradata/racdb/','/u02/oradata/testdb/'
*.log_file_name_convert='/u01/oradata/racdb/','/u02/oradata/testdb/'

Step2: Creating password files
==================================
orapwd file=orapwtestdb password=oracle ignorecase=y entries=5

Step3: Configuring Listener
==============================
First I tried to connect to database without adding any entries

oracle@oradbsrvr2:/appl/oracle>sqlplus sys/oracle@testdb as sysdba

ERROR:
ORA-12528: TNS:listener: all appropriate instances are blocking new connections

After this error I checked the listener status

oracle@oradbsrvr2:/appl/oracle>lsnrctl status

The command completed successfully

testdb instance status was blocked so I added sid_list_listener values

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/oracle/product/11.2.0/grid)

      (SID_NAME = testdb)
      (ORACLE_HOME = /u01/oracle/product/11.2.0/grid)
    )
  )

Then restarted the listener

This error was occurred because the TNS entries of our auxiliary database were missing on the source database. This is required as we are duplicating the active database and it need connection to auxiliary database. After adding TNS entries, the rman process was started again
