Oracle Net Services can find the location of the Autonomous Database wallet using the WALLET_LOCATION parameter in the sqlnet.ora file.

When WALLET_LOCATION is used, Oracle Net Services automatically uses the wallet. The wallet is used transparently to the application. See Prepare for Oracle Call Interface, ODBC, and JDBC OCI Connections with Wallets (mTLS) for information on setting WALLET_LOCATION.

See Download Client Credentials (Wallets) for information on downloading client credentials for Autonomous Database.
