증상
많은 클라이언트가 Microsoft BitLocker 관리 및 모니터링 2.5 복구 데이터베이스에 연결할 때 데이터베이스에 SQL 교착 상태가 발생할 수 있습니다. 따라서 지원 부서 포털 또는 셀프 서비스 포털에서 키를 복구할 수 없습니다. MBAM 서비스가 연결할 수 있게 되 면 암호화 하려고 하면 오류가 발생 하는 새로운 클라이언트. 이렇게 하면 시간 제한 및 기타 오류.
BitLocker 관리 Solution\Logs\Recovery c:\inetpub\Microsoft 및 Service\ 하드웨어 MBAM 서비스 추적 로그에 다음과 같은 오류가 발생 하는 또한 *.svclogs.
트랜잭션 (프로세스 ID 63) 잠금 리소스에서 다른 프로세스와 교착 상태 희생자로 선택 되었습니다. 교착 상태가 발생 합니다. Uncommittable 트랜잭션 된 일괄 처리의 끝에 발견 되었습니다. 트랜잭션이 롤백됩니다.
해결 방법
이 문제를 해결 하려면 MBAM 복구 데이터베이스에 연결 된 저장된 프로시저를 업데이트 합니다. 이렇게 하려면 다음 Transact SQL 스크립트를 실행 합니다.
