Purging Metadata

Purging Metadata

You can delete metadata for a resource from the Metadata Manager warehouse. For example, if you no longer want to analyze metadata from an obsolete metadata source for a resource, delete metadata from the Metadata Manager warehouse. You cannot recover the purged metadata. Back up the Metadata Manager repository database before you purge metadata.
To delete the metadata, purge the metadata for the resource from the Metadata Manager warehouse. Metadata Manager purges all metadata from the warehouse. Purging metadata may take some time, based on the amount of metadata loaded for the resource. After you purge a resource, you can optimize the index to free up disk space used by the indexing files.
When the Metadata Manager warehouse uses Oracle database, you need to assign the CREATE TABLE and EXECUTE PROCEDURE permissions to the user. When you assign the
GRANT CREATE TABLE TO <MM_DB_USER>
permission, make sure you assign the permission to the user or schema of the Metadata Manager warehouse.
If you added custom metadata to the metadata catalog on the
Browse
tab, you can delete the metadata from the catalog using the metadata catalog or by purging it.
  1. On the
    Load
    tab, select the resource for which you want to purge metadata from the Metadata Manager warehouse.
  2. Click
    Actions
    Purge Resource Metadata
    .
    Metadata Manager purges the metadata from the Metadata Manager warehouse and displays the result of the purge operation in the Resources panel.
  3. Optionally, click
    Actions
    Delete Resource
    to delete the resource.
    Metadata Manager deletes the resource and all metadata for the resource from the Metadata Manager warehouse.
