    Abstract: Techniques are provided for using an intermediate cache to provide some of the items involved in a scan operation, while other items involved in the scan operation are provided from primary storage. Techniques are also provided for determining whether to service an I/O request for an item with a copy of the item that resides in the intermediate cache based on factors such as a) an identity of the user for whom the I/O request was submitted, b) an identity of a service that submitted the I/O request, c) an indication of a consumer group to which the I/O request maps, or d) whether the intermediate cache is overloaded. Techniques are also provided for determining whether to store items in an intermediate cache in response to the items being retrieved, based on logical characteristics associated with the requests that retrieve the items.

    Abstract: Techniques are provided for implementing a pluggable database monitoring system that groups running processes for the pluggable database into a grouping and monitors resource usage for the grouping to determine whether to migrate the pluggable database to another container. A system identifies a set of running processes associated with a pluggable database. The pluggable database is hosted on a container DBMS, which is hosted on a virtual machine. The system generates a first grouping that contains the set of running processes. The system monitors, in real-time, aggregated resource usage of the first grouping to determine if the aggregated resource usage exceeds a first threshold. In response to the aggregated resource usage of the first grouping exceeding the first threshold, the system migrates the first pluggable database to a second container DBMS.

    Abstract: Automated management of shared I/O resources involves use of a policy engine for implementing I/O scheduling group I/O policies. The I/O policies are used for determining whether corresponding I/O requests should be issued to a shared storage system immediately or should be delayed via corresponding policy-based queues. In the context of database systems, a database administrator can specify policies regarding how I/O resources should be used and the database system itself enforces the policies, rather than requiring the database administrator enforce the I/O usage of the database and of the individual users.

    Abstract: Techniques are described herein for effectively managing usage of a shared object cache in a container database management system (DBMS). The shared object cache maintains shared objects belonging to a set of pluggable databases (PDBs) hosted by the container DBMS. In an embodiment, a shared object metadata extension structure (SOMEX) is maintained for each PDB. The SOMEX stores metadata for each shared object of the PDB that resides in the shared object cache. In an embodiment, a share of the shared object cache is maintained for shared objects from each PDB in the set of PDBs based on entries in the SOMEX for the PDB.
