You can't unless you give Oracle the access rights on network drive something that should not be given.

As I said give access to network drive to Oracle is a bad idea and a security hole, and even worse to give access to a production server from a test server.
Better go to file transfer.

ORA-39087: directory name %s is invalid
 *Cause:  A corresponding directory object does not exist.
 *Action: Correct the directory object parameter, or create a corresponding
          directory object with the CREATE DIRECTORY command.


Quote:

So you can directly import the object without creating the export dump file (and so transfer) using the NETWORK parameter of impdp.

Either transfer the file, either do it using NETWORK option.
If you don't want to do it in these ways then don't do it.

Maybe you should simply forget it and find someone who is capable of searching the Internet (for already known keywords), reading documentation & examples, understanding what's been read and - finally - implementing newly acquired knowledge.

ok i did this
here i have two server

1. database name livedb -- hostname livedb

2. database name testdb -- hostname testdb

please do this steps on your test db server

host username on both server must be same means on livedb must be its administrator user and on testdb you also login as administrator user

do this steps on your testdb where you want to import

1.Listener service must start with administrator user
2.And instance service also must start with administrator user

To change the default logon for the Oracle services, go to:
-> Control Panel
-> Services
-> OracleServiceXXXX (where XXXX is the instance name)
-> Startup
-> Log On As


Repeat this procedure for the TNS Listener:
-> Control Panel
-> Services
-> OracleXXXXTNSListener (where XXXX is the Oracle Home Name)
-> Startup
-> Log On As



i regularly export on my live db using simple expdp on this exp folder in tso folder so i simple share this tso folder on my livedb

on testdb access this shared folder and right click on this shared folder name tso and click on this map netwrok drive and follow this map network drive steps. after that you can find this shared drive on your testdb my computer

do this steps now on your testdb

Directory created.

-- here livedb its my live database hostname and tso its shared directory and exp its directory where i export my live database using expdp

[b]A directory object has to be created using UNC format to point to the shared directory:

just for testing purpose i export on my livedb using this

C:\Users\Administrator>expdp system/password@livedb schemas=scott directory=exp dumpfile=scott.dmp logfile=expdpscott.log


and import this scott user on this testdb without copy this dumpfile on this testdb server

NO, this is a huge security hole.
Instance service should start with local system user.

thanks


yeah but so many time we have to import table from our live environment to test environment for testing purpose.that time we copy and past this whole dumpfile from live database to test database its take to much time.so this is a best way.i do so many steps but this oracle document id UTL_FILE on Windows NT (Doc ID 45172.1) help me and must import its os username must be same on both database.so here we use administrator user on livedb and testdb so its succeed. another thing its password of this both username must be same on both server.

michel you told me

I didn't say it is not possible, I said you must NOT do it.
Now realize that your test environment has (full) access to your live environment.
Really great for a hacker or anyone who wants to steal your data and/or crash your enterprise business.

If you say so.
Did you never hear that database or system can be hacked?

There is another important point regarding computer security that often gets overlooked: not only is it provided to prevent malicious damage, it is also to safeguard against accidental damage.
