Hi all,

In interview one question was raised how to shift db from one OS to another(say from Windows to Linux) without using exp/imp utility.

And also how to exclude the tables while exporting any user ('coz tables=A,B,C in export is a very long way if one wants to export 100 tables out of 105)

Is there any way.

TIA,
Sachin

Sachin,
that was a trick question meant to confuse you. Answer is you cannot 'successfully' migrate a database from Windows to Linux without using exp/imp. Exp/imp is THE way to migrate databases across different platforms, becos the datafiles are OS specific.

You cannot exclude tables in OWNER level export. You can do a user level export and exclude them during the import .. Or you can do pattern matching in table level export to export a bunch of tables(if you find it difficult to type in )..

Again if you want to export 100 of the 105 tables, you will and should be doing User level export anyway !
