80 results about "Abnormal end" patented technology

An AbEnd (also abnormal end or abend) is an abnormal termination of software, or a program crash. This usage derives from an error message from the IBM OS/360, IBM zOS operating systems. Usually capitalized, but may appear as "abend". The most common were ABEND 0C7 (Data exception) and ABEND 0CB (Division by zero). Abends could be "soft" (allowing automatic recovery) or "hard" (terminating the activity).

Adding scalability and fault tolerance to generic finite state machine frameworks for use in automated incident management of cloud computing infrastructures

A scalable and fault tolerant finite state machine engine, for example, for use in an automated incident management system, logs or records data in persistent storage at different points or levels during various internal processing of an event associated with an information technology element, and action taken associated with the event, by executing a finite state machine instance that encodes policies for handling incidents on such types of information technology elements. In the event that the finite state machine engine is shutdown during processing, the finite state machine engine is able to pick up from where it left off when it was shutdown, for each abnormally terminated finite state machine instance, by using the data logged in the persistent storage and determining a point of processing from where it should continue its execution.

Method and system for intelligent and adaptive exception handling

A method and system for handling errors and exceptions in an ERP environment are disclosed. According to one aspect of the present invention, a condition or event causes a script-engine associated with a particular ERP server to generate an error message. The error message is communicated to a centralized controller-node. The centralized controller-node analyzes the message and determines the best course of action for handling an error or exception related to the error message. Based on the controller node's analysis, the controller node communicates a response message, thereby enabling the process that caused the error to continue without terminating abnormally.

Method and system for transmitting data for data synchronization between server and client when data synchronization session was abnormally terminated

Disclosed is a method for transmitting data for data synchronization between a server and a client. If a data synchronization session in a network is abnormally terminated, the client stores state information of data to be transmitted, which indicates states of the data at the time of the abnormal termination. The state information of the data makes it possible to resume the data transmission beginning with data items that were being transmitted at the time of the abnormal termination. Since one of the server and the client transmits only data that has not been received by the other, it is possible to decrease the time necessary to complete the data synchronization and also to reduce a wasteful, unnecessary transaction when synchronization of a large amount of data is performed.

Nested Recovery Scope Management For Stateless Recovery Agents

Nested recovery scope management systems and methods for a multiple process computer system having a dynamic multiple address space server are disclosed. Stateless recovery agents are employed, under the control of a supervisory program called Recovery Director, during initialization or restart of servers to restore recoverable data in response to identified failures or other abnormal termination. The Director controls the recovery of protected resources in a systematic manner. The Director is initialized when a first address space of a first server is started. Then, as each instance of a recoverable component is initialized, the component registers with the Director by providing a reference to a stateless recovery agent that can later perform recovery functions for it if needed. As part of the registration, a token representing the current failure scope of the registration is generated and provided to the recoverable component by the Director. Work identifiers representing recoverable operations can be generated from or associated with this token by the recoverable component and may be put in hardened storage. Upon initialization of a new server region, and also upon a failure or abnormal termination, the Director groups multiple instances of the same recoverable component together, formulates an iterative recovery plan, and determines the scope of recovery by examining its hardened data for failure scopes involving a recoverable component that may need to perform some recovery operation. As such recoverable components are identified, the Director references the associated recovery agent, provides it with appropriate token as to the recovery scope. The recovery agent is then allowed to carry out those recoveries, including any recovery scopes nested within.

Method for detecting abnormal termination during model detection

The invention discloses a method for detecting abnormal termination during model detection. In the method, a counter example path is generated and recorded by constructing E', describing the E' and performing a model detection process. The counter example path provides detail execution steps for an extended finite state machine (EFSM) model under a variable configuration corresponding to the EFSM model, and the latest part of the counter example path provides information of a terminable state in a trap state. According to logic expressed by the EFSM model, whether a termination state under the variable configuration is the terminable state can be easily determined. If the termination state under the variable configuration is not the terminable state, an abnormal termination phenomenon in the terminable state is detected under the corresponding variable configuration; and if the termination state under the variable configuration is the terminable state, the abnormal termination phenomenon in the terminable state is not detected. Therefore, the detection method provided by the invention realizes the detection of the abnormal termination phenomenon.
