Oracle - Guide to Oracle Cloud: 5 Steps to Ensure a Successful Move to the Cloud

In this web log mail service I demonstrate how to consign Oracle Database schemas into dump files. These dump files can then be imported into some other Oracle DB or Democratic Data Warehouse (ADW). In this post, I use SQL Developer to run the Data Export Wizard.
In order to access the Data Pump export Wizard, beginning display the DBA window from the View bill of fare. Add together the connexion to the source database to export from. So under that connectedness, navigate down to Data Pump -> Export Jobs. Right click and select the Run Data Consign Magician.
In that location are a few dissimilar types of information pump exports. In this example, I chose to exercise a Schema export. This allows me to merge several schemas from unlike source databases into the same target ADW.

Nosotros tin can export one or multiple schemas at the aforementioned time by selecting them.

If the purpose of the export is to afterward import the information dump into ADW, it is recommended to exclude certain database objects that are not necessary on ADW. For case, operation is probable meliorate without creating indexes on ADW, and that is why we exclude them from the export. The following type of objects are recommended to be excluded for ADW purposes: Index, Index Type, Cluster, Materialized View, Materialized View Log, Materialized Zonemap, and DB Link.

Annotation the VERSION dropdown in the following screen. If you are going to import later into a lower version Oracle DB, you want to gear up the version number to that of the target database. Since my aim hither is to later on import into ADW, I kept it to the default value of Uniform.

On the following screen, select the DIRECTORY that will contain the output dump files. This directory needs to be created before you lot go on, in case you don't already have a directory setup with the proper permissions to export files to. Employ the following SQL control to create a directory if you don't already have one. You tin run this using SQL Developer:
In the following instance, the name of the DIRECTORY is DP_FROM_ONPREM:

CREATE DIRECTORY DP_FROM_ONPREM AS '/u01/app/oracle/admin/ORCL/dpdump/files';

Notice that my File Name in the following screenshot ends with %U. This tells the wizard to use a numeric increment on the suffix of the file name, in case I end up with an export that consists of more one file. This will happen if the export is large in size. You tin command how large each of the export files tin can be. In my example, I set up it to exist ~2GB for each file.

Once you finish the wizard, y'all will see a new consign job added in the DBA window. When yous click on the job it shows whether it is withal executing or if it'due south stopped. You can likewise see the log of the execution in the lower window. As the export is running, navigate to the directory that you prepare for the dump files and verify that they are created in there.
