Abstract
Techniques are disclosed for managing access to shared computing resources in a computing system which include representing resources as objects and managing access to those objects using the construct of a resource instance manager. A set of resource instance managers responds to all commands requesting access to a set of respective shared resources. Access to each shared resource is managed by a unique resource instance manager for that resource which maintains a consistent state for that shared resource. Each resource instance manager determines, in response to receiving requests to allow execution of commands and using a set of predefined rues, whether those commands may be safely executed concurrently with other commands acting on the same shared resource. If the commands cannot be executed concurrently, the resource instance managers change the order in which queued commands are executed or abort execution of one or more commands.
