# Oracle PDBs and CDBs

# Oracle pluggable database and container database discovery {#ariaid-title1}

Release version: Yokohama  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 minutes to read  
The ServiceNow Discovery application can discover Oracle pluggable databases (PDBs) and container databases (CDBs). Discovering some of these resources might 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) website 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://www.servicenow.com/docs/r/store-release-notes/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=yokohama&pubname=yokohama-platform-security&ft:locale=en-US) or (for UNIX only) [Oracle Wallet authentication](https://www.servicenow.com/docs/m3ylp7_~xsnVF9p_jzBBdg "Enable Oracle Wallet authentication to use credentials stored on the target server during Oracle database discovery on UNIX systems.")
* For Windows, configure [Windows credentials](https://www.servicenow.com/docs/access?context=r_WindowsCredentialsForm&version=yokohama&pubname=yokohama-platform-security&ft:locale=en-US)
* For Unix, configure [SSH credentials](https://www.servicenow.com/docs/access?context=r_SSHCredentialsForm&version=yokohama&pubname=yokohama-platform-security&ft:locale=en-US)
* For the Oracle database, configure [Oracle database discovery](https://www.servicenow.com/docs/QQnW_68M83zshoDAJxWdPA "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_os2_hgv_w3b}
{#oracle-cdb-pdb-discovery__ul_c4h_mcj_hkb}  
Note:  
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}

| Table and field | Description |
|-|-|
| cmdb_ci_db_ora_pdb_instance: Relation Type : Managed By​​ ||
| sid | Name of the PDB instance​​ |
| name | Name of the CI in CMDB. This is a combination of sid and the hostname​. |
| version | Version of the PDB as taken from the CDB instance​​ |
| edition | Edition of the PDB as taken from the CDB instance​​ |
| install_directory | Install directory of the PDB as taken from the CDB instance |
| oracle_home​ | Oracle home of the PDB as taken from the CDB instance |
| cdb_name | Name of the cdb sid that contains the PDB. This refers to the Oracle database instance configuration item (CI​) |
| cmdb_ci_db_instance_size: Relation Type : Contained By​​ ||
| sid | Name of the Oracle database CDB/PDB instance​​ |
| name | Name of the CI in CMDB. This is a combination of the sid and the hostname. |
| db_size | Total size allocated to the database instance |
