Intro
Oracle Key Vault (OKV) plays a vital role in the AI era, where data security, encryption, and regulatory compliance are more critical than ever. OKV communicates securely with its targets using KMIP (Key Management Interoperability Protocol) over TLS. In simple terms, without a properly configured OKV Endpoint (EP), OKV cannot communicate with the target system.Installing the Endpoint is essential because it provides the secure link between the database and OKV.
Before installing the OKV Endpoint agent, there are several prerequisites to consider. One of the most important is the correct folder structure. All required directories must be created directly under the
wallet_root
location.Folder structure required for OKV installation.
mkdir -p /u01/app/oracle/admin/TCDB/wallet_root/tde - Location for TDE keys
mkdir -p /u01/app/oracle/admin/TCDB/wallet_root/okv - Location for OKV End point
mkdir -p /u01/app/oracle/admin/TCDB/wallet_root/tde_seps - Location for External SSO Key
After extracting the OKV Endpoint binary, it's important to run the provided health check script. This script validates the endpoint configuration, ensuring everything is set up correctly. If there are any issues especially with the folder structure the health check will flag them.
The OKV health check scripts are located in the
bin
directory of the extracted endpoint package. Below is a sample taken from an Oracle DBCS (Database Cloud Service) instance:
[oracle@dbsdpl55 bin]$ pwd
/opt/oracle/dcs/commonstore/wallets/PWHSE01_3c9_yyz/okv/bin
[oracle@dbsdpl55 bin]$ ls -lrth
total 8.4M
-rw-r--r-- 1 oracle oinstall 0 May 23 11:11 okv.log.0
-rwxr-x--- 1 oracle oinstall 5.3K May 23 15:03 root.sh
-rwxr-x--- 1 oracle oinstall 8.0K May 23 15:03 okvutil
-rwxr-x--- 1 oracle oinstall 29K May 23 15:03 okv_ssh_ep_lookup_authorized_keys
-rwxr-x--- 1 oracle oinstall 8.4M May 23 15:03 okveps.x64
-rwxr-x--- 1 oracle oinstall 20K May 23 15:03 ep_healthcheck.sh
[oracle@dbsdpl55 bin]$
Executing OKV Endpoint Health Check.
Once the OKV Endpoint binary is extracted and the environment is set up, you should run the health check script to validate the configuration. Below is a sample output from a DBCS environment:
[oracle@dbsdpl55 bin]$ ./ep_healthcheck.sh

Conclusion
In today's AI-driven landscape, where safeguarding sensitive data is paramount, Oracle Key Vault (OKV) offers a robust and centralized approach to managing encryption keys and secrets. A correctly configured OKV Endpoint (EP) is not just a technical requirement—it is the foundation for secure communication between the database and OKV. By ensuring the proper setup of the EP, including the necessary folder structures and successful health checks, organizations can enforce strong encryption practices, maintain compliance, and confidently protect their data assets in both on-premises and cloud environments.
