Abstract: Objects across multiple database manipulation language (DML) redo log records are cached, during continuous replay of redo log records on a secondary system, for the same table partition to enable reuse of such cached objects. Later, these cached objects can be reused as they are accessed during the sequential processing of DML redo records for a specific table partition.

Abstract: Testing a database replication system within a multi-container system architecture comprises receiving a first request for creating a database recovery system within a multi-container system architecture. The multi-container system architecture is configured to contain a plurality of tenant databases and a system database, and the database recovery system includes a primary system and a secondary system. The primary system is then identified from the information in the first request. Upon identification, a first tenant database included in the plurality of tenant databases is determined that corresponds to the identified primary system. Upon determining the first tenant database, a second tenant database of the plurality of tenant database is generated that corresponds to the secondary system, and which is enabled to test replicating information that would otherwise be associated with the first tenant database. Related apparatus, systems, techniques and articles are also described.
