A transactional name server. One or more objects of the name server are managed as transactional objects, thereby providing a transactional name server. Atomic updates are provided in the name server by the addition of transactional semantics. The transactional semantics include making the objects of the name space managed objects and providing a local interface to a directory service that propagates a transactional context from the name server through a directory down to a resource manager.

Resolution of a compound name of an object may indicate that a disjunction exists within the object name. This disjunction represents a foreign binding indicating that the resolve cannot be completed on one system or an alias name of the object. When a disjunction in the object name is identified, the object associated with the disjunction is obtained. Thereafter, a resolve operation on that object is performed using at least a portion of the object name.

An object factory is registered under multiple interface names. The interface names have an inheritance relationship with an object implementation associated with the object factory. The names are registered in a repository of a name space, such as a Life Cycle Repository. Thus, an object factory can be located using any one of the interface names.

An exemplary embodiment of the invention relates to a method, system, and storage medium for providing context-based dynamic policy assignment in a distributed processing environment. The system includes a first resource management host in communication with a client system, an application executable by the first resource management host, a dynamic policy assignment system executing on the first resource management host, policies stored on the first resource management host and an application profile associated with the client system. The application profile is received by the first resource management host. Application hosting services include executing the application on behalf of the client system. The dynamic policy assignment system receives the request, and based upon a task name associated with the application profile, selects at least one policy for an application instance. The dynamic policy assignment system further associates the policy to the application, and the host system executes the application.

A Structured External Storage (SES) Facility is coupled to one or more Central Electronic Complex (CEC) Processors, each linked to each other in a System Processing Complex (Sysplex). Applications within a CEC communicate with the SES via messages over a communication means. The SES comprises one or more List Structures, each structure comprising one or more Lists, each List comprising a list control and none or more List Entries. List Entries may be keyed or unkeyed, have a List Entry Identifiers (LEID), created within the SES, and unique within a particular List Structure. List Entries may also have a unique (within a List Structure) Name, created and managed by the application. A plurality of List commands are provided for creating, locating, moving and deleting List Entries--with location reference possible by LEID, Name, Key, Location within List, or a combination of Key and Location within Key. Name and LEID are preserved between moves, while Key may or may not be changed, and will be used to determine relative location.

A Branch in Subspace Group (BSG) instruction is executed in problem state (for example by an application program) for providing a fast instruction branch between address spaces within a restricted group of address spaces called a subspace group. The subspace group contains two types of address spaces: a base space and any number of subspaces. The subspace group is set up in a control table associated with each dispatchable unit (DU). This DU control table contains: an identifier of a base space, an identifier of an access list that contains identifiers of all subspaces in the subspace group, an indicator of whether CPU control was last given to a subspace or to the base space, and an identifier of a last entered subspace in the group. The BSG instruction has an operand defining a general register containing the target virtual address and an associated access register containing an access-list-entry token (ALET) defining the target address space. The ALET indexes to a target subspace identifier in the access list, and then the associated virtual address locates the target instruction in the identified target address space. BSG instruction execution controls restrict the BSG branching only to an instruction in the subspace group.
摘要:
An application, executing on a first processing element in a MP system without an asymmetric feature, issues an instruction requiring that feature to complete. A program check interruption gives control to interrupt handlers, which create a high-priority, non-preemptable work unit control block and enters the dispatcher to enqueue the work unit on a processor-related queue associated with a second processing element having the asymmetric feature. When the dispatcher executes in the second processing element, it executes the non-preemptable work unit, which transfers control to the application at the point of interruption. Subsequently the application has only whatever processor affinity obtained prior to the program check.
