Fault handling in a distributed IT environment

摘要

An improved method provides fault handling in a distributed IT environment. The distributed IT environment executes at least one workflow application interacting with at least one application by using interface information about the at least one application. The method comprises: storing at least one fault handling description in a implementation-independent meta language associated with the at least one application; associating the interface information with the at least one fault handling description based on at least one defined fault handling policy, created based on at least one service definition; and the workflow application if a fault response from the at least one application is received: retrieving at least one associated fault handling description based on at least one fault handling policy, and interpreting and executing a particular meta language code of the at least one associated fault handling description in order to continue the defined workflow application.

1. A method for fault handling in a distributed IT environment that executes at least one workflow application interacting with at least one application by using interface information about the at least one application, wherein the method comprises:
the at least one workflow application receiving a fault response from the at least one application; using at least one fault handling policy, the at least one workflow application dynamically performing a self-adaptive selection, from a fault handling descriptions catalogue of an externalized storage repository, of at least one fault handling description that is associated with the at least one fault handling policy, wherein the at least one fault handling policy comprises an interface information that is associated with the at least one application, and wherein the fault handling descriptions catalogue comprises the at least one fault handling description that is stored in an implementation-independent meta language; associating the interface information about the at least one application with the at least one fault handling description based on the at least one fault handling policy which is created based on at least one service definition, wherein the at least one fault handling policy corresponds to a fault response; generating a fault handler for performing a dynamic fault handling execution at runtime based on the at least one fault handling description, wherein the fault handler is executable and interpretable in a specific target platform language associated with a target runtime platform, and wherein the target runtime platform is the workflow runtime environment; and implementing the fault handler to interpret and execute a particular execution language code of the at least one fault handling description in order to continue execution of the at least one workflow application.
