Perhaps EXP's TNSNAMES.ORA doesn't see the database. Search the board for use of the TNS_ADMIN system variable; it might help.

Does this directory (d:\oracle\product\10.0.1\db_1) contain TNSNAMES.ORA file? Is it not in ...\network\admin (by default)?

Please, try to understand what's being written.

Your TNSNAMES.ORA file says:

Quote:

# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora

Quote:

And i Set Tns_admin in d:\oracle\product\10.0.1\db_1

Backup? This is the first time you've ever mentioned backup. Export is not a backup. Moreover, it appears that this topic is misplaced - it has nothing to do with Forms. So, where would you want it to be moved? "Server Utilities" (which deal with Export problems) or "Backup & Recovery"?

Export utility is fine for moving data around; for backup, you might want to check what RMAN (Recovery Manager) offers. For more information, read Introduction to backup and follow links suggested in that document.

As for TNSNAMES.ORA: I have created a directory in the root directory of my C drive and put TNSNAMES.ORA file in there. Then I have set TNS_ADMIN environment variable to point to that directory.

I maintain TNSNAMES.ORA file manually, using a simple text editor (such as Notepad). I don't use Net Configuration Assistant.

Perhaps you should leave it for a day, just to clear your mind.

Then re-read everything we've said, including topics you've found on the Forum (and, perhaps, elsewhere).

Then start over.

Because, no - solution is not changing some file manually. This is how I maintain my TNSNAMES.ORA file, which doesn't mean that everyone else must do that as well.

Because you didn't issue the command in such a way that it is saved for future sessions.

Search this forum for 'tns_admin' and you will see that you need to set it through the environment handler.

If in doubt, use the windows help facility.
