Oracle Wallet Manager is the graphical Java tool for creating and maintaining Oracle wallets, the PKCS#12 containers that hold TLS certificates, private keys and, in many deployments, the Transparent Data Encryption keystore and secure external password store entries.

Migrations care because wallets hold material the migration itself depends on: the TDE master key needed to read encrypted tablespaces during export, and the certificates used for TLS connections from migration tooling. Moving key management to Azure Key Vault starts with an inventory of wallets, and scripts that invoked the GUI must be rewritten around command-line tools.

Oracle's 21c Upgrade Guide deprecates Oracle Wallet Manager (notice dated May 2021), and the 26ai guide desupports it (notice dated April 2023), recommending the orapki command-line tool instead.

Oracle Wallet Manager, born before 11.2, maintained PKCS#12 wallets containing TDE master keys, TLS certificates, and stored credentials. It served these security duties with the quiet gravity expected of a wallet.

Deprecated in 21c and desupported in 26ai, it leaves Oracle work to the orapki command-line tool. Azure offers no wallet file to migrate; keys are instead generated or imported into Key Vault.

It is survived by Azure Key Vault for customer-managed TDE keys, where it lives on partly. The server identity needs key permissions, while managed certificates, Key Vault secrets, or Microsoft Entra authentication assume its other responsibilities.
