You can import the same file into two instances simultaneously, because
imp doesn't lock the import file, unless the import file was produced
by simultaneous export into the same file from two different instances,
in which case you have something what is scientifically known as
monster mess
Jerry,
There shouldn't be any problem. It's better to use different log files or run
them in different directories.

Hi all,
I have dump files (1 table 1 dump file, dump filename is tablename)
How to create imp scripts that will import all those dump files without any
referential problem
Something like this:
select 'imp system/manager file=./' || object_name || '.dmp || ' fromuser=myuser
touser=myuser
Add IGNORE=Y into imp statement

Maybe you can do this:
1) imp index=n constraint=n
2) imp ignore=y rows=no
