How to get the entire database from remote server to my server

Question

Hi,
I am running a web application with sample data. Now i need to access the original data through this application. But the original data is located in the other server which is located in Mumbai.
Now i need the copy of that database to my system(Chennai). with minimum effort.
It is very urgent...
Thanks in advance...

Hi
Nicolas is right. You can also take advantage of exp/imp utility. That would not only get the entire db in one file but also the size will be a fraction of the entire db size.You can search for DataPump (that uses expdp and impdp) utility to expedite the export/import process.
For simple exp/imp you can do the following.
From Remote site(MUMBAI) issue
ORACLE_HOME\BIN\exp file=c:\fulldbexp09sept05.dmp log=c:\fulldbexp09sept05log.log FULL=Y userid=system/pwd@connectstringOfyourdb
Get a copy of fulldbexp09sept05.dmp and place it on your local drive in Chennai
On Local Site (Chennai)
ORACLE_HOME\BIN\imp file=fulldbexp09sept05.dmp log=fulldbimp09sept05 FULL=Y userid=system/pwd@connectstringOfyourlocaldb
By this you can take advantage of having a different db name on remote and local sites. This is a fairly easy exercise. You just need to be sure that in your TNSNAMES.ORA you have correctly defined the connectString for your db.
PS: Create a database on local server with default settings.
Make use of following to create appropriate tablespaces and users if you desire ie.
1. On Remote Site open SQLPLUS session and issue this command to find out the tablespaces, datafiles and their sizes
SQL>SELECT SUBSTR(file_name,1,60) FILE_NAME, tablespace_name, bytes
FROM dba_data_files
GROUP BY tablespace_name, file_name;
Now create the tablespaces on local sites using the result of the above query.
2. On Remote Site open SQLPLUS session and issue this command to spool user creation script.
SQL>spool c:\createuserscript.lst
SQL> SELECT 'CREATE USER ||' IDENTIFIED BY VALUES '||'"'||PASSWORD||'"'||' DEFAULT TABLESPACE '||DEFAULT_TABLESPACE||' TEMPORARY TABLESPACE '||TEMPORARY_TABLESPACE||';'
FROM dba_users
WHERE username NOT IN ('SYS','SYSTEM')
ORDER BY username;
SQL>spool off
Now edit this createuserscript using any editor and replace " with '. Copy this file to the local server and run it using @. This will create appropriate users.
Let me know if you have any problems.

Nicolas I am not sure as how to eliminate the " in my script. Any comment will be appreciated.
