摘要

Methods and apparatus for upgrading a plurality of databases are disclosed. For example, a computer system may receive a first upgrade order associated with a first database. The system then receives a second upgrade order associated with a second database, wherein the first upgrade order is indicative of a first higher upgrade precedence than the second upgrade order. The system then receives a first priority associated with a third database. The system then receives a second priority associated with a fourth database wherein the first priority is indicative of a second higher upgrade precedence than the second priority. The system then upgrades the first database first in time based on the first upgrade order. The system then upgrades the second database second in time based on the second upgrade order. The system then upgrades the third database third in time based on the first priority. The system then upgrades the fourth database fourth in time based on the second priority.
