Bei mir trat unter Ubuntu 20.04 LTS und Ubuntu 22.04 LTS ein merkwürdiges, merkwürdiges Verhalten auf (dafür gibt es nicht genug Adjektive).
Dies ist ein IBM Db2-Testserver. Der Server führt einen Db2-Dienst unter der Benutzer-ID db2inst1 (UID 1002) aus. Der Servername lautet srv-db2-teste.
Jedes Mal, wenn ich von einem Remotecomputer aus mit der Benutzer-ID db2inst1 einen scpoder einen rsyncauf dem Server srv-db2-teste ausführe, werden nach dem erfolgreichen Kopieren der Dateien ALLE unter der Benutzer-ID laufenden Dienste (ich sage ALLE DIENSTE) beendet! Unabhängig davon, welcher Prozess ausgeführt wird, werden alle unter dem Benutzer db2inst1 laufenden Prozesse beendet.
Db2 läuft auf Port 50000, aber ich habe andere Ports getestet und es beendet immer noch Prozesse.
Beispiel: Auf einem Remotecomputer führe ich diesen Kopierbefehl aus:
dba@workstation1:~$ scp /db2/files/* db2inst1@srv-db2-teste:/db2/files/
Ich habe es mit anderen Benutzer-IDs getestet und das Verhalten ist das gleiche: Alle Prozesse sind außer dem Benutzer „root“ ausgefallen (habe nicht verstanden, warum „root“ intakt ist).
Wenn db2top (Db2-Anwendung) nach dem Remote-SCP abstürzt, wird folgender Fehler angezeigt:
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
(semctl (*id,0,IPC_RMID, (union semun) x)): Invalid argument
db2inst1@srv-db2-teste:~$

So etwas habe ich noch nie gesehen. Ich bin für jede Hilfe sehr dankbar!
