Table Space Management   «Prev 

Oracle Transportable Tablespaces

First step in the process is to change the tablespace you wish to transport into READ ONLY status. This example shows the command to change the WAREHOUSE1 tablespace so that it is in READ ONLY status. If you are exporting a set of tablespaces, repeat this command for each one. 

EXP PARFILE ='parameterfile'
Parameter file contents
Second step in the process is to export the tablespace. This screen shows the syntax of the command you will use and the actual export command used in our example. You create a parameter file that contains all the details needed to export the file. The green highlighted area show optional parameters that can save exporting time if used with the 'n' option. For example, if you know that there are no grants you wish to export, specify GRANTS =n and the export process will skip this portion of its routine.

The next step is to copy the export file just created and all the data files for the tablespaces to a location that is accessible by the target database. This screen shows you how you might accomplish this in the Windows environment using Windows Explorer, but you use any operating system tool that you prefer for copying and pasting the files.

Now use the import utility (IMP) to import the meta-data into the target database. This screen shows the syntax and the exact command for our sample tablespace, WAREHOUSE1. The details are again placed into a parameter file that is named in the IMP command. The green highlight shows optional parameters for listing all the owners in the tablespace (TTSOWNERS) and listing how to substitute one owner for another (FROM USER and TOUSER) when doing the import process. When these are left out, the owners of all the object remain unchanged.

You can now modify the tablespace so that it is in a READ WRITE state using the command show here.
