Hi,

To create the aux instance perform the followe ing steps:-

1. create the directory bdump, udump, cdump, pfile.

2.copy the prod database init.ora file to the location where u want to craete the aux instance.

3.If u want to create the aux instance at the same host change the db_name parameter value to different name for example aux1 or if u want to create the aux instance at the different host then u can continue at the same db_name.

4. Change the bdump, cdump, udump path at the init.ora file.

5. Change the controlfile path where u want to create the control file.

6. Create the ora password file by using orapwd.

7. configure the tnsnames.ora file at the aux instance and the listener.ora file at the target database.

8.connect through sql prompt using pfile parameter.
sql> startup force nomount pfile='<full path>';

9. create spfile.
sql> create spfile from pfile;

"lock_name_space" is the parameter if u want to create your aux instance at the same host. if it is for different host no need to space the "lock_name_space" parameter.

I followed all steps but prompt following message, how to resole this error. I have two virtual machine one has Primary DB named "orcl" and on second PC i want to create stand by DB but Auxiliary instance is unable to start.

SQL> startup nomount pfile='init.ora';
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00130: invalid listener address '(ADDRESS=(PROTOCOL=TCP)(HOST=server2)(PORT=1521))'
SQL>

Following is listener.ora configuration.(Stand By DB Machine)
"
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orclstby)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orclstby)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = ORCL)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.3.17.13)(PORT = 1521))
)

ADR_BASE_LISTENER = /u01/app/oracle
"

Following is listener.ora configuration.(Primary DB Machine)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

STEP1 Install oracle database software auxiliary host.

STEP2 Create an Oracle Password File for the Auxiliary Instance
Orapwd file=C:\oracle\product\10.2.0\db_1\DATABASE\PWDLHDUP.ora password=DUP

STEP3 Create an Initialization Parameter File for the Auxiliary Instance
Use following list of commands to create parameters file using existing/target DB. This file will be used in creation of new auxiliary
instance.

Login to Target DB
-------------------
SQL>SYS/****@LHR AS SYSDB
SQL>Create pfile='C:\initLHDUP.ora' from spfile;

The file will be created on existing/target host copy or move newly created file to Auxiliary host
C:\oracle\product\10.2.0\db_1\DATABASE\initLHDUP.ora

Modify parameters. All path parameter should be accessible on Auxiliary host.

db_name='LHDUP'
db_file_name_convert=
('d:\oracle_data_files\oradata\LHDB',
'c:\oracle_data_files\LHDUP\oradata')

log_file_name_convert=
('d:\oracle_data_files\oradata\LHDB',
'c:\oracle_data_files\LHDUP\oradata')

control_files=
'C:\oracle_data_files\LHDUP\oradata\control01.ctl',
'C:\oracle_data_files\LHDUP\oradata\control02.ctl',
'C:\oracle_data_files\LHDUP\oradata\control03.ctl'

compatible='10.2.0.1.0'
db_block_size=8192 #The block size for the auxiliary database must match that of the target DB
db_cache_size=50331648
java_pool_size=25165824
large_pool_size=4194304
shared_pool_size=33554432
streams_pool_size=0
pga_aggregate_target=16777216
sga_max_size=113246208
sga_target=167772160

audit_file_dest='C:\oracle_data_files\LHDUP\admin\adump'
background_dump_dest='C:\oracle_data_files\LHDUP\admin\bdump'
core_dump_dest='C:\oracle_data_files\LHDUP\admin\cdump'
user_dump_dest='C:\oracle_data_files\LHDUP\admin\udump'

STEP4 Create directory structure on duplicate host

C:\flash_recovery_area\LHDB\BACKUPSET
C:\oracle_data_files\LHDUP\oradata
C:\oracle_data_files\LHDUP\admin
C:\oracle_data_files\LHDUP\flash_recovery_area\ARCHIVELOG
C:\oracle_data_files\LHDUP\admin\adump
C:\oracle_data_files\LHDUP\admin\bdump
C:\oracle_data_files\LHDUP\admin\cdump
C:\oracle_data_files\LHDUP\admin\udump
C:\oracle_data_files\LHDUP\admin\dpdump
C:\oracle_data_files\LHDUP\admin\pfile
C:\oracle_data_files\LHDUP\admin\scripts

STEP-4 Create Auxiliary Instance

ORADIM -NEW -SID LHDUP -intpwd change_on_install -startmode auto
-pfile 'c:\oracle\product\10.2.0\db_1\database\initLHDUP.ora'

ORADIM -NEW -SID LHDUP -startmode auto -pfile
'c:\oracle\product\10.2.0\db_1\database\initLHDUP.ora'

ORADIM -DELETE -SID LHDUP # to delete existing instance
SET ORACLE_SID=LHDUP
