发明名称 ENHANCED RECOVERY OF HIGHLY AVAILABLE COMPUTING SYSTEMS
摘要 Exemplary embodiments disclose a method and system for detecting a failure and resuming processing in a computing system encompassing at least two sites, a primary site and a secondary site. In a module, an exemplary embodiment generates a record of a logically consistent state and data of system components of the primary site periodically and transfers the record of a logically consistent state and data of system components of the primary site to the secondary site. In another module, an exemplary embodiment detects a failure in the primary site, halts the generation of the record of a logically consistent state and data of system components of the primary site periodically with a data freeze function, and resumes a processing of the primary site on the secondary site with secondary site components updated with a most recent logically consistent state and data of system components of the primary site.

主权项 1. A method for detecting a failure and resuming processing in a computing system encompassing at least two sites, a primary site and a secondary site, the method comprising: generating a record of a logically consistent state and data of system components of the primary site periodically; transferring a record of a logically consistent state and data of system components of the primary site to the secondary site; updating a state and data of system components of the secondary site with the contents of a record of a logically consistent state and data of system components of the primary site; detecting a failure in the primary site; halting the generation of a record of a logically consistent state and data of system components of the primary site periodically with a data freeze function upon detecting a failure; and resuming a processing of the primary site on the secondary site with secondary site components updated with a most recent logically consistent state and data of system components of the primary site.
