Netværksadgang nægtet af adgangskontrolliste (ACL) i Oracle Database 11g

Jeg lavede denne opgradering, og det var timers arbejde. Det hele skal laves anderledes for version 12. Hvert procedurekald skal have en commit. Den generelle idé er, at du opretter en adgang, tilføjer detaljer, giver privilegier. Du skal vide:

  • dit mailservernavn og -port
  • om du har brug for en bruger og adgangskode for at få adgang til det (sandsynligvis ikke)
  • den bruger, der vil ringe til postpakken, er nemmere, hvis de også ejer postpakken
