The ServiceNow Discovery application can discover pluggable databases (PDBs) and container databases (CDBs), which are features of Oracle Database 12c. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
A PDB is a portable collection of schemas, schema objects, and non-schema objects that
appear to an Oracle Net client as a separate database. A collection of PDBs is called a
container database (CDB).

For more information about PDBs and CDBs, see [What are CDBs, PDBs and Containers?](http://www.oracle-wiki.net/premium:startdocsminimulticdbs)

## Request apps on the Store {#oracle-cdb-pdb-discovery__section_gvb_cql_rlb}

Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://docs.servicenow.com/bundle/store-release-notes/page/release-notes/store/sn-store-release-notes.html).{#oracle-cdb-pdb-discovery__inline-send-to-store}

## Prerequisites {#oracle-cdb-pdb-discovery__section_s3d_tkh_w3b}

Set the user credentials and grant permissions:

* Configure [Applicative credentials](https://www.servicenow.com/docs/access?context=applicative-creds&version=australia&pubname=australia-platform-security&ft:locale=en-US).
* For Windows, configure [Windows credentials](https://www.servicenow.com/docs/access?context=r_WindowsCredentialsForm&version=australia&pubname=australia-platform-security&ft:locale=en-US)
* For Unix, configure [SSH credentials](https://www.servicenow.com/docs/access?context=r_SSHCredentialsForm&version=australia&pubname=australia-platform-security&ft:locale=en-US)
* For the Oracle database, configure [Oracle database discovery](https://servicenow-prod.fluidtopics.net/4KaIxxw2jNS1GM8lc6PQXg "Discovery can identify an Oracle database instance that is running on UNIX or Windows operating systems. It can also find Oracle clusterware, which runs Real Application Clusters (RAC).")
* Provide a user with permissions to run queries on the following tables:
  * V$DATAFILE
  * V$TEMPFILE
  * V$LOG
  * DBA_FREE_SPACE
  * V$DATABASE
  * V$PDBS
  * V$PARAMETER

{#oracle-cdb-pdb-discovery__ul_c4h_mcj_hkb}  
Hinweis:  
Set applicative credentials at the CDB level to discover relationships for PDBs and the CDB size only. Alternatively, set applicative credentials at the CDB/PDB level to discover relationships for PDBs and the CDB/PDB size. If you do not set applicative credentials at the CDB level, no PDB attributes are discovered.

## Data collected during Discovery {#oracle-cdb-pdb-discovery__section_uhs_zf5_w3b}

Discovery collects the following data:{#oracle-cdb-pdb-discovery__table_ktj_ph5_w3b__entry__2}
