Oracle metadata tool

Yes, I think I have seen a couple of DW with more than 65, fields in them. Hi D90, There is a sample workbook for download on our website..

The whole product is there including runtime as a development license. The idea is for people to try it out for themselves during development for free so they can decide for themselves if they want it.

On number of fields….. The article is here:. You might find 10, fields that people say they want, and you might actually build it, but I would argue that in very few companies where managers NEED 10, fields to support their decision making processes. I am working on some models now and, including keys, there is no single industry vertical that is running at more than 5, fields. When you combine a number of verticals that might go together, we are up to around 6, fields….

Fact tables have lots of keys. And even at 5, fields that is what I would consider a LOT….. In any case, as we all but eliminate the cost of writing and supporting ETL subsystems we will be able to put more and more information into the EDW that is economically viable……. I will update it as I have more to offer the community.

To transfer the metadata from one partition to another, you export the metadata from the partition and then import it into the other partition. From the navigation pane, expand the farm, expand Application Deployments , then select the application. Click Export. The Export dialog box is displayed, as shown in the following figure:.

If you check Exclude base documents, this operation exports only the customizations, not the base documents. See Section The target path must be accessible from the system where the application is running. The path must be a directory that currently exists. The metadata is written to a subdirectory of the directory that you specified, with the name of the partition that was exported as the name of the subdirectory. From the navigation pane for the production system, expand the farm, expand Application Deployments , then select the application.

In the Import dialog box, enter the directory specification that contains the exported metadata. Include the subdirectory with the partition name in the specification. The path must be accessible from the system where the application is running. The path can be a directory or an archive. You can move from a file-based repository to a database-based repository.

You cannot move from a database-based repository to a file-based repository. To minimize downtime, take the following steps to move an application's metadata from a file-based repository to a database-based repository:. Use RCU to create schemas in the new repository, as described in Section Export the metadata from the source partition to a directory on the file system:.

You can delete metadata partitions if there are no applications either deployed to the partition or referring to the partition. You may want to delete a metadata partition from the repository in the following circumstances:. When you undeploy an application.

Oracle Fusion Middleware leaves the metadata partition because you may still want the metadata, such as user customizations, in the partition. If you do not need the metadata, you can delete the partition. When you have transferred metadata from one partition to another and configured the application to use the new partition. For example, to delete the metadata partition from the file-based repository repository1, use the following command:.

To delete a metadata partition from a repository partition using Fusion Middleware Control:. In the Repository Partitions section, select the partition and click Delete. For database-based MDS repositories, you can purge the metadata version history from a partition. File-based MDS repositories do not maintain version history. This operation purges version history of unlabeled documents from the application's repository partition. The tip version the latest version is not purged, even if it is unlabeled.

To purge labeled documents, you must first delete the label, as described in Section Consider purging metadata version history on a regular basis as part of MDS Repository maintenance, when you suspect that the database is running out of space or performance is becoming slower. This operation may be performance intensive, so plan to do it in a maintenance window or when the system is not busy. For specific recommendations for particular types of applications, see the documentation for a particular component.

You specify the documents to be purged by using the olderThan parameter, specifying the number of seconds. The following example purges all documents older than seconds:. In the Purge all unlabeled past versions that are older than field, enter a number and select the unit of time.

For example, enter 3 and select months. A metadata label is a means of selecting a particular version of each object from a metadata repository partition. Conceptually, it is a collection of document versions, one version per document, representing a horizontal stripe through the various document versions.

This stripe comprises the document versions which were the tip versions latest versions at the time the label was created. Document versions belonging to a label are not deleted by automatic purging, unless the label is explicitly deleted. In this way, creating a label guarantees that a view of the metadata as it was at the time to label was created will remain available until the label is deleted. You can use a label to view the metadata as it was at the point in time when the label was created.

You can use the commands to support logical backup and recovery of an application's metadata contained in the partition. If the application has more than one version, you must use the applicationVersion parameter to specify the version. To find the labels associated with an application, use the listMetadataLabels command, as described in Section You can list the metadata labels for a particular application.

You can promote documents associated with a metadata label so that they are now the last version. That is, you can promote them to the tip. Promote a label if you want to roll back to an earlier version of all of the documents captured by the label.

For example to promote the label prod1, use the following command:. The following topics describe how to manage the metadata repository schemas:. For information about changing the character set of metadata repository that is stored in an Oracle Database, see Oracle Database Globalization Support Guide :. Oracle recommends using Unicode for all new system deployments.

Deploying your systems in Unicode offers many advantages in usability, compatibility, and extensibility. Oracle Database enables you to deploy high-performing systems faster and more easily while utilizing the advantages of Unicode.

Even if you do not need to support multilingual data today, nor have any requirement for Unicode, it is still likely to be the best choice for a new system in the long run and will ultimately save you time and money as well as give you competitive advantages in the long term. With RCU, you can also drop component schemas. Note: Oracle recommends that all metadata repositories reside on a database at the same site as the components to minimize network latency issues.

You should deploy your applications to MDS in the following situations, so that the metadata can be managed after deployment: The application contains seeded metadata packaged in a MAR. You want to enable user personalizations at run time.

You have a custom Oracle WebCenter application. Note the following when you use the MDS operations described in the following sections: The export operation exports a versioned stripe of metadata documents from an MDS Repository partition to a file system directory.
