  Oracle Tips by Burleson

Oracle 10g Instantiating with Transportable Tablespace

DATAFILES=('/oradata/sales_ts.dmp') STREAMS_INSTANTIATION=y

As seen in this example, when you run the import command, make sure you set the streams_instantiation import parameter to Y. This parameter ensures that the import records export SCN information for each object imported. Performing the import automatically sets the instantiation SCN for all the imported objects at the destination database.

  1. Alter the tablespace to enable read and write operations at both the source and destination databases. Once the import completes, you can switch the tablespaces back to read-write mode at the source and destination databases.

ALTER TABLESPACE sales READ WRITE;

Thus, the following new data dictionary views enable you to determine which database objects have a set instantiation SCN at the schema and global level:

DBA_APPLY_INSTANTIATED_SCHEMAS
DBA_APPLY_INSTANTIATED_GLOBAL

Also, note that it is possible now to recursively set the schema and global instantiation system change numbers (SCNs). A new recursive parameter in the set_schema_instantiation_scn and set_global_instantiation_scn procedures enables you to set the instantiation SCN for a schema or database, respectively, and for all of the database objects in the schema or database.
