A virtual memory system that maintains a list of pages that are required to be resident in a frame buffer to guarantee the eventual forward progress of a graphics application context running on a graphics system composed of multiple clients. Pages that are required to be in the frame buffer memory are never swapped out of that memory. The required page list can be dynamically sized or fixed sized. A tag file is used to prevent page swapping of a page from the frame buffer that is required to make forward progress. A forward progress indicator signifies that a page faulting client has made forward progress on behalf of a context. The presence of a forward progress indicator is used to clear the tag file, thus enabling page swapping of the previously tagged pages from the frame buffer memory.

In a J2EE application server, a method of passing context information among transactions in a hierarchical parent-child transaction chain executing in a single thread of execution. The method comprises generating a correlator corresponding to a top level transaction spawning a plurality of child transactions in the parent-child transaction chain. The correlator is stored in a Java thread local (JTL) stack associated with the thread of execution. For each child transaction, the JTL stack is referenced to access a correlator associated with a parent of the child transaction. The method further comprises utilizing context information provided by said parent correlator to generate a correlator for said child transaction.

A small footprint device can securely run multiple programs from unrelated vendors by the inclusion of a context barrier isolating the execution of the programs. The context barrier performs security checks to see that principal and object are within the same namespace or memory space and to see that a requested action is appropriate for an object to be operated upon. Each program or set of programs runs in a separate context. Access from one program to another program across the context barrier can be achieved under controlled circumstances by using an entry point object. The entry point object can either perform accesses across the context barrier on behalf of a requesting program or can pass the request to the program to be accessed and switch contexts to the program to be accessed.

The invention reduces the operation of switch the applying program and optimizes the system resource, which stores the present working environment automatically and restores the entire environment when the accident occurs in the computer.

A small footprint device can securely run multiple programs from unrelated vendors by the inclusion of a context barrier isolating the execution of the programs. The context barrier performs security checks to see that principal and object are within the same namespace or memory space or to see that a requested action is authorized for an object to be operated upon. Each program or set of programs runs in a separate context. Access from one program to another program across the context barrier can be achieved under controlled circumstances by using shared interface objects. Shared interface objects have a property that permits them to be accessed across the context barrier regardless of security restrictions that would otherwise apply. Shared interface objects, however, may enforce their own security rules independently of the context barrier.

A computer-implemented method for collecting trace streams in application code, instruments the application code to detect an application context. The application context includes static and dynamic attributes. The method also includes steps of: achieving the application context a first time, collecting static attributes of the application context, determining a name for the application context based on static attributes, sending the application context name to the trace subsystem and receiving a trace stream handle in return, storing the trace-stream handle and marking the application context such that achieving the same application context later in the program execution is recognizable, receiving the application context name by the trace subsystem, registering the context name in the trace subsystem, returning from the trace subsystem a unique trace stream handle for each unique application context, achieving the instrumented application context after the first time including access to stored trace stream handle, sending dynamic information and the trace stream handle of the application context to the trace subsystem, sending the application context names and associated sequence of dynamic information to trace analysis tools, and receiving the application context names and associated sequence of dynamic information in a trace analysis tool.

Method and apparatus for preserving program context when causing execution of a probe routine from a target routine of an executable computer program code. Executable code for the probe routine is created such that the probe routine does not reference a first set of registers that are usable by the target routine. A modified version of the target routine is created to cause execution of the probe routine. The modified version of the target routine is performed instead of the original version when the target routine is called during program execution. A second set of registers on the processor register stack is allocated when the probe routine is invoked. The second set of registers is not manipulated by the probe routine so as to avoid changing contents of registers of the register stack that are used by the target routine.

A system and method for securely restoring software program context is presented. A special purpose processor core is included in a heterogeneous processing environment where each processor can access a shared memory. The isolated special purpose processor core includes an isolated local memory. The isolated special purpose processor core receives an identifier corresponding to the secured program. The identifier is used to read an encrypted context of the secured program from the shared memory. The encrypted context is decrypted using an encryption key. The decrypted context is stored in the isolated special purpose processor core's local memory. The secured program's context integrity is verified by using a persistent security data that is retrieved from a secure location, such as a persistent storage register that can only be accessed when the special purpose processor core is running in isolation mode. If the context is verified, the secured program is executed.

Service provisioning in mobile terminals is provided through registering and transferring of application context, which permits substantially seamless transfer of application functionality across administrative service domains. An architecture for providing application context transfer may include access routers, transcoder proxy servers, and gateway routers. A mobile terminal served by a current access router creates an application context for a session and registers it with the current access router. Around the time of handoff, the current access router transfers the application context to a new access router associated with a new administrative domain and a new access network. The new access router evaluates the application context and takes steps to provide application functionality for the mobile terminal and current sessions. These steps may include the use of a network entity, such as a transcoder proxy server, to modify data for a session and thereby provide application functionality in the new administrative domain.
