    Import / Tablespace

    Hello,

    I have again a question conerning import of data. I exported a database with the parameter full=y.
    Is it possible to import the data of only one tablespace from the exported dump-file? And if yes, how I can do it?

    Regards

    By using datapump You can use remap_tablespace option to import objects of one tablespace to another tablespace

    Poster doesn't mention using expdp. It looks like poster did a plain "exp full=y" and wants to import the content of a single tablespace which in such a scenario can't be done.

    I think expdp is a feature of Oracle 10g, right? I forgot to say I want to import th content of one tablespace on a Oracle 9.2 instance.

    But it seems not to work according to PAVB statement.

    Another question. I have saved the *.dbf files of the tablespace, too. Is it possible to replace the old tablespace with the actual tablespace? Or will an error occured after mounting the instance?

    Regards

    Don't do it in you "live" database; you are going to kill it.

    The good news is that you can use your saved datafiles by creating a new "cloned" database pointing to them, once you have it up-and-running you can export all objects sitting on your infamous tablespace and then import them into your "live" database.

    If you know the contents of that tablespace (or get them from the DDL generated with show=y) you could import those particular objects (tables) for the tablespace of your desires.
