It leverages discovery patterns instead of multiple probes to detect Oracle installations, with the option to revert to probes if needed. The discovery process collects detailed configuration and version data, cluster information, and Oracle options, populating the CMDB with comprehensive Oracle database instance records. Show full answer Show less ## Credentials and Permissions * **Applicative credentials:** Mandatory for executing SQL queries and connecting to database links. The database user must have access to the `tnsnames.ora` file and permission to run SQLPlus and SELECT queries on specific Oracle tables. * **Oracle Wallet authentication:** Supported on UNIX as an alternative to applicative credentials. * **Windows credentials:** Required for Windows targets with read access to `tnsnames.ora`. * **SSH credentials:** Required for UNIX targets with read permissions on `oratab` and system parameter files. * **Sudo permissions:** Needed for certain Oracle clusterware commands that read cluster and resource status. ## Discovery Process and Requirements * Oracle instances on UNIX are identified by the `orapmon` process; on Windows by `oracle.exe`. * Discovery collects data from Oracle system files and commands, including clusterware information using specific commands to retrieve cluster nodes, status, resources, and VIP configurations. * Patterns replace probes for new instance discovery, triggered by a Horizontal discovery probe configured on classifiers. ## Data Collected * **Oracle Instances:** Details such as SID, install directory, version, parameter files, Oracle Home, edition, hostname, and TCP ports are gathered for both UNIX and Windows instances. * **Oracle clusterware:** Information about clusters, nodes, resources, virtual IPs, and statuses is collected and stored in corresponding CMDB tables. * **Oracle options:** Enabled options on instances are discovered using a legacy pattern extension requiring the Software Asset Management Professional for Oracle plugin, with data including usage statistics and licensing information. * **Extended instance attributes:** Additional attributes like container database status, database unique name, and replication status can be collected via an extension included in the Discovery and Service Mapping Patterns application. ## Managing Oracle Instances on Virtual Machines and Cloud When Oracle instances run on virtual machines, relationships are created connecting Oracle instances to their host computers or servers, indicating virtualized environments. For instances hosted on AWS or Azure clouds, ServiceNow tracks the virtualization chain from the Oracle instance to virtual machines and datacenters, capturing vCPU counts and hosting details. ## Key Practical Considerations for ServiceNow Customers * Ensure applicative, SSH, and Windows credentials have required permissions on target hosts and Oracle files to enable successful discovery. * Verify the `tnsnames.ora` file is correctly configured and accessible by discovery credentials. * Configure the Horizontal discovery probe properly on classifiers to trigger Oracle discovery patterns. * Install necessary plugins such as Software Asset Management Professional for Oracle to discover Oracle options. * For Oracle clusterware discovery, confirm sudo permissions for required commands and ensure processes like `crsd.bin` are running. * Use the Extend Oracle instance extension to enrich CMDB data with additional Oracle attributes. * Be aware that RAC single-node discovery is not supported by the Oracle DB on Unix and Windows patterns. ## Additional Resources Customers can refer to related ServiceNow documentation for configuring horizontal pattern probes, Oracle catalog discovery, and pluggable database/container database discovery. Oracle's official documentation is also recommended for detailed understanding of Oracle options and usage scripts. 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). Patterns perform the discovery of Oracle installations. These patterns replace several probes for new instances. If you want to continue to use probes, you can deactivate the Horizontal discovery probe, which launches the pattern, and then activate the necessary probes. Note: Oracle DB on Unix and Oracle DB on Windows do not support RAC single-node discovery. The Oracle DB on Unix and Oracle DB on Windows patterns discover Oracle catalog objects through the pattern extension Get Catalog info. For more information, see [Oracle Catalog discovery](https://www.servicenow.com/docs/PbP_QZkcSbZ9p_3~A~XGPw "The Discovery and Service Mapping Patterns application uses the Get Catalog info pattern extension of the Oracle DB on Unix and Oracle DB on Windows patterns to find Oracle Catalog objects. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). For general information about database catalog discovery, see [database catalogs](https://www.servicenow.com/docs/QiUDM4DAO2Ap0zujMEbVdQ "The database catalog lists all the catalog objects, or databases, discovered for an instance of a database."). Note: For information on Probe to Pattern migration see the knowledge article [KB0694477](https://support.servicenow.com/kb_view.do?sysparm_article=KB0694477). ## Credentials Configure these credentials:{#c_OracleDatabaseDiscovery__table_gmd_2kx_jz__entry__2} | Credential type | Additional information | |-|-| | [Applicative credentials](https://www.servicenow.com/docs/access?context=applicative-creds&version=australia&pubname=australia-platform-security&ft:locale=en-US) | Applicative credentials are mandatory for two use cases: * Executing SQL queries against the remote Oracle DB Instance * Creating connections to database links * Software Asset Management activated {#c_OracleDatabaseDiscovery__ul_w51_dz2_kgb} You must add the database user you configured during Oracle database installation.

Ensure this process is running in the IP range you designate for Discovery. Discovery identifies a running instance of an Oracle database on Windows from the oracle.exe process. Ensure this process is running in the IP range you designate. For Oracle clusterware, you also need permissions to read [the `/etc/hosts/` file](https://docs.oracle.com/cd/E37670_01/E41138/html/ch11s02s01.html), which associates host names with IP addresses.
