Answer 1

This is script for Standby..
Primary Server Configuration
1.In the TNSNAMES.ORA of Primary DB add the entry of the Standby DB
IRCSSTDB(This is the service name in Primary DB to connect to Standby DB) =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = IRDBACK)(PORT = 1512))
(CONNECT_DATA =
(SERVICE_NAME = IRCS(This is the actual INSTANCE name of Running DB on Standby DB)
2. There is no need to Make any Changes in the Listener.ora of PRIMARY DB
Keep LISTENER.ORA of Primary as it is
Copy Listener.ora from Primary DB to Standby DB and make following changes
Delete All the Extra Existing listeners.
(These Updations are for the STANDBY DB)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = IRDBACK)(PORT = 1521))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /ora01/app/oracle/product/9.2.0)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = IRCS)
(ORACLE_HOME = /ora01/app/oracle/product/9.2.0))
3.In the INIT.ORA of Primary DB add Following…
log_archive_dest_2 = "service=STBY optional/Mandatory scope=BOTH"
log_archive_dest_2 = Enable
log_archive_min_succeed_dest = 2
We can add this Dynamically with the SQL*PLUS..
Standby DB Server Configuration
1.In the TNSNAMES.ORA of Standby DB add the entry of the Primary DB
primary1(ISSL)(This is the service name in Standby DB to connect to Primary DB)=
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp) (PORT=1521) (HOST=PRIMARY MACHINE NAME))
(CONNECT_DATA=(SERVICE_NAME=IRCS(This is the actual INSTANCE name of Running DB on Primary DB)
2.Copy Listener.ora from Primary DB to Standby DB and make following changes
Same as Above
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = IRDBACK)(PORT = 1521))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /ora01/app/oracle/product/9.2.0)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = IRCS)
(ORACLE_HOME = /ora01/app/oracle/product/9.2.0))
3. Connect to Idle instance..
1.C:\ oradim –NEW –SID ircs –INTPWD pwdfilename –STARTMODE auto –pfile E:\oracle\oradata\pfile\init.ora
2.     C:\ set oracle_sid=IRCS
3.     C:\ sqlplus /nolog
4.     SQL:>connect sys/ircl as SYSDBA
5.     SQL:>startup nomount pfile= E:\oracle\oradata\pfile\init.ora
6.     SQL:> alter database mount standby database;
7. SQL :> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE;
4. we can also add these parameter in INIT.ORA of Standby DB
1.standby_archive_dest= /u00/app/oracle/admin/sec/arch (Same path as in
(log_archive_dest_1) in init.ora
2. Fal_client=standby1 (Service Name)
3. Fal_server=primary1 (Service Name)
Troubleshooting….
1. Check Init.ora of Primary DB
2. Try to open Standby Database in normal mode try to connect it with normal user from different Machine.
3.check *.logs file on Standby Database
4.Check v$archive_dest on Primary DB
5. lsnrctl services <listener name>….For Checking Listener, for service
