Abstract: Techniques are described herein for isolating a network stack in a multitenant container DBMS. A first and second pluggable database are established within a container database. A first network stack is assigned to the first pluggable database and a second network stack is assigned to the second pluggable database. A request is received to connect to the first pluggable database and a connection is established to the first pluggable database using the first network stack. A request is received to connect to the second pluggable database and a connection is established to the second pluggable database using the second network stack.

Abstract: Techniques are described herein for isolating runtime environments in a multitenant container DBMS. A CDB may contain a database dictionary that defines a plurality of pluggable databases and a respective database nest for each pluggable database. Each respective database nest of said each pluggable database is associated with different operating system privileges. When database sessions are established on a container DBMS, each database session is given access to a pluggable database by attaching the respective database nest of the pluggable database to each database session.

Abstract: Disclosed is an approach to implement an on-demand secure communications channel to a cloud-related resource that is located in a customer's on-premises data center, where the on-demand channel provides access to the resource to a cloud provider's operator employees. This creates on a temporary basis all of the infrastructure that is needed to allow the operational access to the customer system, which can then be destroyed once it is no longer needed.

Abstract: Techniques are described herein for intelligent pooling and management of isolated hierarchical runtimes in a multi-tenant environment. In an embodiment, an allocation of operating system resources of a container database management system (CDBMS) is allocated to each generic nest of a pool of generic nests. The allocation includes a quota of one or more processors and a quota of memory. A configuration profile for a PDB in the CDBMS is then determined. Based on the configuration profile determined for the PDB, a matching generic nest from the pool of generic nests is determined. A matching generic nest is assigned to the PDB. The matching generic nest is then configured for the PDB.
