analyzing, by a container database management system (CDBMS), an administration request;

identifying and generating, by the CDBMS and based on said analyzing the administration request, a plurality of administrative tasks that administer one or more pluggable databases in a container database, wherein the plurality of administrative tasks comprises a first subset plurality of administrative tasks and a second subset plurality of administrative tasks;

identifying a dependency of a first administrative task of the first subset plurality of administrative tasks on a second administrative task of the first subset plurality of administrative tasks;

detecting a lack of dependency of the second subset plurality of administrative tasks on the first subset plurality of administrative tasks;

enqueuing as ready to execute, based on said detecting said lack of dependency, the second administrative task on a first queue of a first thread or core and the second subset plurality of the administrative tasks on a second queue of a second thread or core;

deferring, based on said identifying said dependency, enqueuing the first administrative task until after completion of the second administrative task; and

executing, by said first thread or core, the second administrative task concurrent to executing, by said second thread or core, the second subset plurality of the administrative tasks.
