Export selected tables?

I am using Oracle 8, with exp80 and trying to export only a few selected
tables. From the Windows XP or Windows NT Dos prompt
I use exp80 Userid=user/pass then with asks Tables I put a t
and it begins asking for tables names and this works fine.
I then tried to run by a batch job with the following.
exp80 sysytem/mang fromuser=user touser=user file=c:\select.dmp tables=(
table1, table2, table3) log=c:\select.log full=n buffer=4096.
I get ORA-06402 error NETCMN invalid driver designated.
What could I be doing wrong?

This is the explanation for that error message:

Error:  ORA 6402  Text:   NETCMN:  error receiving break message  Cause:  The SQL*Net driver detected that its server has unexpectedly exited. Action: Check the network operating system and resubmit the connect string.

But there is a problem with your export.  You do not use fromuser or touser in an export, take those out and it should run o.k.

What do you mean by server has unexpectedly excite.
What should I use instead of fromuser & touser?
Thanks for your response.
The error message indicates that possibly your server was not available. Are you sure the server was up when you ran the batch job? Does it run at night, did you test it during the day?

You don't use anything instead of fromuser, touser, take them out of your command line statement:

exp80 system/manager file=c:\select.dmp tables=(table1,
table2, table3) log=c:\select.log full=n buffer=4096

Yes the server is available, I did export form DOS command
and it worked but batch won't.
You mean i don't need a user name and password?
Thanks again for your response..
The username and password is system/manager in this scenario, those are still there.  The fromuser and touser parameters are for import, not export, so I've taken them out.

This is what I would do. Put all parameters in a paramter file, for example select.par, which would look like this:

tables=(table1, table2, table3)

And then your command line would be simple:

exp80 parfile=select.par
exp80 parfile=c:\select.par

or whatever the path might be.
If batch still won't work, try using the connect string in your user parm:


where testdb is a connect string in your tnsnames file.

Niether of these work.
I'm open to anything.
try this:

 exp80 user/pass@service_name file=table_dump.dmp tables=table_a,table_b,...  log=table_dump.log

you need to find service name from your tnsnames.ora.

This worked at the DOS command line and I also
made a batch file with that in it and it worked.
