INTELLIGENT POOLING OF ISOLATED HIERARCHICAL RUNTIMES FOR CLOUD SCALE DATABASES IN MULTI-TENANT ENVIRONMENT

摘要

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.
