Abstract
Embodiments provide a migration instruction that effectuates the migration of a pluggable database from a source database server instance to a destination database server instance. Upon receiving the migration instruction, the migrating pluggable database is opened at the destination instance. Connections are terminated at the source instance at a rate that is determined based on statistics maintained for one or more of: the migrating pluggable database, the source instance, the destination instance, a container database, etc. Furthermore, once the migration instruction is received, a certain amount of time is provided before the source instance flushes the dirty buffers for the migrating pluggable database from the buffer cache of the source instance. The delay in flushing dirty buffers from buffer cache allows the source instance to provide data blocks, of the migrating pluggable database, directly to the destination database server instance from the cache.
