HAI,
IT'S EASY.OPEN THE TNSNAMES.ORA FILE WHICH IS IN THE ORACLE_PATHNETWORKADMIN DIRECTORY.OPEN IN THE NOTEPAD.CREATE ONE ENTRY FOR YOUR TWO DATABASES.
TEST1.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = YOUR ORACLE hostname)(PORT = 1521))
)
(CONNECT_DATA =
(ORACLE_SID=YOUR DATABASE SID)
)
)
IN THE ABOVE ENTRY,GIVE YOUR ORACLE SERVER NAME OR IP ADDRESS AND ORACLE DATABASE SID.
THEN YOU CAN CONNECT WITH THE TWO SERVERS FROM YOUR LOCAL MACHINE.
IF YOU WANT TO CONNECT THE HP WITH NT DATABASE,THEN YOU SHOULD GO FOR THE DATABASE .
DO AS FOLLOWS
BEFORE CREATING THE DATABASE LINK,WE HAVE TO DO SOME CONFIGURATION.
i am giving one example for you.
for example take the first database
(
sid=orcl
database name=oracle
db_domain=uk.com
host string=ss1
)
first edit the parameter file for the following
db_domain=uk.com
then start the database
In the svrmgr30.exe or sqldba execute this command
alter database rename global_name orcl.uk.com;
(name should be sid.db_domain)
then you execute this command
select * from global_name;
then you got the global database name for that
database like
orcl.uk.com
then go to the second database
(sid=tan
databasename=tani
db_domain=usa.com
host string=ss2
)
edit the parameter file for that database
db_domain=usa.com
start the database
execute this command in the svrmgr30 or sqldba
alter database rename global_name tan.usa.com;
(if in this server also the sid is orcl
don't worry.but only thing is
you should have different
db_domain parameter in each database)
execute this query
select * from global_name;
tan.usa.com
go to the first database
then create the database link by following
(execute this command in the first database)
create database link tan.usa.com
conect to system identified by manager
using 'ss2';
note :
the database link name should be the global database
name for the another database
if you have any problem ,please mail to me
