ERROR in Standby database setup with RH9

[Cherrish Vaidiyan]

sir,
The following are the steps that i followed in setting up standby
database on Red hat Linux 9. i am using Oracle 9i.

i have followed the steps in this site :

http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96653/create_ps.htm#66206

Still i give the steps i followed.
[I] Preparing the Primary Database for Standby Database Creation

Before you create a standby database you must first ensure that the
primary database is properly configured.
Place the primary database in FORCE LOGGING mode after database
creation using the following SQL statement:

SQLALTER DATABASE FORCE LOGGING;

Ensure that the primary database is in ARCHIVELOG mode, that automatic
archiving is enabled, and that you have defined a local archiving
destination.

Set the local archive destination using the following SQL statement:

SQLALTER SYSTEM SET
LOG_ARCHIVE_DES T_1='LOCATION=/disk1/oracle/oradata/payroll
2MANDATORY' SCOPE=BOTH;

[II] Identify the Primary Database Datafiles

On the primary database, query the V$DATAFILE view to list the files
that will be used to create the physical standby database, as follows:

SQLSELECT NAME FROM V$DATAFILE;
[III] Make a Copy of the Primary Database

On the primary database, perform the following steps to make a closed
backup copy of the primary database.
Step 1 Shut down the primary database.

SQLSHUTDOWN IMMEDIATE;

Step 2 Copy the datafiles to a temporary location.

Step 3 Restart the primary database.

SQLSTARTUP;

[IV] Create a Control File for the Standby Database

SQLALTER DATABASE CREATE STANDBY CONTROLFILE AS
2'/disk1/oracle/oradata/payroll/standby/payroll2.ctl';

[V] Prepare the Initialization Parameter File to be Copied to the
Standby Database

Create a traditional text initialization parameter file from the
server parameter file used by the primary database; a traditional text
initialization parameter file can be copied to the standby location
and modified

SQLCREATE PFILE='/disk1/oracle/dbs/initpayroll2.or a' FROM SPFILE;

[VI] Copy Files from the Primary System to the Standby System

[VII] Set Initialization Parameters on a Physical Standby Database

Although most of the initialization parameter settings in the text
initialization parameter file that you copied from the primary system
are also appropriate for the physical standby database, some
modifications need to be made.

db_name=PAYROLL
compatible=9.2. 0.1.0
control_files='/disk1/oracle/oradata/payroll/standby/payroll2.ctl'
log_archive_sta rt=TRUE
standby_archive _dest='/disk1/oracle/oradata/payroll/standby'
db_file_name_co nvert=('/disk1/oracle/oradata/payroll/',
'/disk1/oracle/oradata/payroll/standby/')
log_file_name_c onvert=('/disk1/oracle/oradata/payroll/',
'/disk1/oracle/oradata/payroll/standby/')
log_archive_for mat=log%d_%t_%s .arc
log_archive_des t_1=('LOCATION=/disk1/oracle/oradata/payroll/standby/')
standby_file_ma nagement=AUTO
remote_archive_ enable=TRUE
instance_name=P AYROLL2
# The following parameter is required only if the primary and standby
databases
# are located on the same system.
lock_name_space =PAYROLL2

@@@@@@@@@@@@@@@ @@@@@@@@@@@@@@@ @@@@@@@@@@@@@@@ @@@@@@@@
I got some doubts here in modifying parameters :

1) Is the db_name kept same as that of primary ?
2) I think i have to give path of standby control file that i have
created.. right ?
3)Wat abt value in 'db_file_name_c onvert' & 'log_file_name_ convert'
parameter ? what is the first path that i have to give ?my primary
database is in another system..

[VIII] Configure Listeners for the Primary and Standby Databases

[IX] Enable Dead Connection Detection on the Standby System

Enable dead connection detection by setting the SQLNET.EXPIRE_T IME
parameter to 2 in the SQLNET.ORA parameter file on the standby system.
For example:

SQLNET.EXPIRE_T IME=2

[X] Create Oracle Net Service Names

[XI]Create a Server Parameter File for the Standby Database
SQLCREATE SPFILE FROM PFILE='initpayr oll2.ora';

[XII] Start the Physical Standby Database

On the standby database, issue the following SQL statements to start
and mount the database in standby mode:

SQLSTARTUP NOMOUNT;
SQLALTER DATABASE MOUNT STANDBY DATABASE;

############### ############### ############### #########
now i get the following error... can u help me out wats the problem???
the error is

SQLalter database mount standby database;
alter database mount standby database
*
ERROR at line 1:
ORA-01102: cannot mount database in EXCLUSIVE mode
############### ############### ############### ##########

Can anyone experienced such a problem..? pls do help me .. if anyone
can give me in personal mail pls donot hesitate.
