If you are using Oracle 8i and higher, and your OS has been configured to support large files, then the exp utility should have no problem creating a dump file larger than 2 GB. If your OS has not been configured to support large files, then you will not be able to create any file larger than 2 GB, no matter what you do. Verify with your SysAdmin that you can create large files on your server.
We used to employ a trick to create a dump file larger than 2 GB when the exp utility would not support these file sizes. The trick is to create a pipe on your filesystem. The exp utility writes to the pipe which immediately passes the data to another utility (gzip in the example below). To exp, the file never is more than a few KB in size. Follow these steps:
mknod exp.pipe p gzip < exp.pipe > expdat.dmp.gz & exp userid=system file=exp.pipe full=yImporting is similar to the following:
gunzip < exp.dat.dmp.gz > exp.pipe & imp userid=system file=exp.pipe full=y
