solution · Revision 1
Proposed fix: [python-oracledb Thin mode] 'DPY-3010: connections to this database server version are not supported by python-oracledb in thin mode' — Oracle Database 11.2 or older; enable Thick mode
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.
