Hi Masters,

I need to import data to production database. The database details are not in tnsnames.ora.

I am using easy connect method to connect to the database, since I am not able to edit tnsnames.ora.

Is there any way by which I can do the import ?

Can I do it like this

imp system/pwd@imp system/pwd@'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxx)(PORT=1521)))(C
ONNECT_DATA=(SID=xx))' ......................

another little know fact about SQL*Net on *NIX systems is below

bcm@bcm-laptop:~$ cat ./.tnsnames.ora
BCM=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=V112)))
bcm@bcm-laptop:~$

Any OS user can create their own private tnsnames.ora file as shown above.
The file resides in $HOME is named tnsnames.ora & preceeded with a period character.
SQL*Net will utilize this file PRIOR to looking for any other tnsnames.ora files as shown below

bcm@bcm-laptop:~$ sqlplus scott/tiger@bcm

The even "littler" known fact is that is also true for Windows.

I know, because some years ago I was searching for hours why my boss couldn't connect to a new database before I found a tnsnames.ora in his home directory from years ago. (%HOMEPATH%)

Alternatively have TNS_ADMIN variable point to any directory where you have write access & place tnsnames.ora file there.
