Abstract
A two phase move technique for moving groups of tables may reduce cross-host communication and length of table locks. A group including a first table and a second table may be moved to the destination host system. This is done by creating a third table replicating the first table and creating a fourth table replicating the second table on the destination host, and replicas of other tables in the group. The tables in the group are not locked against modifications during the creation of the replica tables. After the creation of the replicas, roles of the original tables and the created tables are switched such that the original tables are set to the replica role and the created tables stored on the destination are set to the source role. The original tables are dropped after the switching of the roles.
