Agent 게이트웨이의 실제 Managed Host 이름(예: branch-gateway)을 확인합니다. Fixed TCP는 일반 TCP와 별도의 공인 엔드포인트 풀을 사용하므로 기존 Remote Service의 포트 풀 유형을 임의로 변경하지 마세요.
실패하면 Server 정책, Agent system diagnostics, DB 서비스 리스너, 외부 포트 개방을 각각 점검합니다. DB 자체 인증/TLS는 그대로 필요합니다. 서비스 철회 시 소유 Agent에서 unset remote-service branch-oracle로 해당 Remote Service만 제거합니다. 운영 DB 세션 중단 가능성을 검토한 뒤 실행하세요.
Fixed TCP는 별도 Server 엔드포인트 풀을 쓰는 Service Object 하위 유형입니다. 기존 Remote Service를 표준 TCP/Fixed TCP 풀 사이에서 제자리 변경할 수 없습니다. 공개 포트가 DB 대상 포트와 같다고 가정하지 말고 show remote-service branch-oracle 결과를 사용하세요.현재 CLI 전체 목록 · MCP 호환성
