Recommended action: Enable Thick mode (install Oracle Client libraries, call oracledb.init_oracle_client()) — supports DB 9.2+ — or upgrade the database. Option: Enable Thick mode [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. Install Oracle Instant Client 2. oracledb.init_oracle_client() before connecting Expected: Command proceeds without the error.
