Ubuntu 20.04 LTS 및 Ubuntu 22.04 LTS에서 이상하고 이상한 동작(형용사가 충분하지 않음)이 발생했습니다.
IBM Db2 테스트 서버입니다. 서버는 db2inst1 사용자 ID(UID 1002)로 Db2 서비스를 실행합니다. 서버 이름은 srv-db2-teste입니다.
scpdb2inst1 사용자 ID를 사용하여 원격 시스템에서 srv-db2-teste 서버로 a 또는 a를 실행할 때마다 rsync파일을 성공적으로 복사한 후 사용자 ID(모든 서비스라고 함)로 실행 중인 모든 서비스가 종료됩니다! 실행 중인 프로세스에 관계없이 db2inst1 사용자로 실행 중인 모든 프로세스가 작동 중지됩니다.
Db2는 포트 50000에서 실행 중이지만 다른 포트를 테스트했는데 여전히 프로세스가 종료됩니다.
예: 원격 시스템에서 다음 복사 명령을 실행합니다.
dba@workstation1:~$ scp /db2/files/* db2inst1@srv-db2-teste:/db2/files/
다른 사용자 ID로 테스트했는데 동작은 동일합니다. 사용자 루트를 제외한 모든 프로세스가 다운되었습니다(루트가 그대로 유지되는 이유를 이해하지 못했습니다).
원격 scp 이후에 db2top(Db2 애플리케이션)에 충돌이 발생하면 다음 오류가 발생합니다.
SQL1224N The database manager is not able to accept new requests, has
terminated all requests in progress, or has terminated the specified request
because of an error or a forced interrupt. SQLSTATE=55032

나는 이런 것을 본 적이 없습니다. 어떤 도움이라도 대단히 감사하겠습니다!
