Transportable tablespaces is one of the fastest ways to do the job.

 

by: oleggoldPosted on 2009-10-07 at 06:38:11ID: 25515167

Looks like in this case ,as in 2 previous versions the fastest method would transportable tablespaces

 

by: oleggoldPosted on 2009-10-07 at 06:43:14ID: 25515226

syntax
exp user/pass@db TRANSPORT_TABLESPACE TABLESPACES  (        list of tablespaces to export)

 export transportable tablespace metadata (default=N)

exp user/pass@db TRANSPORT_TABLESPACE TABLESPACES

Thanks schwertner, oleggold,

1. if the tablespace is not available on the target db...would this create relevant tablespace?
2. if I want to import these tables, indexs into a different tablespace...Is there an option in the command to override with the tblspace name. would this work this way?
3. In my case...user name will be same for sure, but cannot gurantee the tablespace name it might be tblspace1 in DEV, SIT..but different in UAT.

Thanks

You can create tablespace on the target instance.
But this will have meaning only in the future.
The main task of "Transportable Tablespaces" is to move DATA in the tablespace.
After that you have also to move Dictionary data about the moved data.
Doing this you will move irrelevant data and this is too bad.

The conclussion is that if you create from scratch similar tablespace you have also to
create from scratch the data in the tablespace.

You can move tables and indexes from one tablespace to another one. There are appropriate Oracle statements to do this. You can use them before or after the move.
