    Abstract: Fault tolerant operation is disclosed for a primary instance, such as a process, thread, application, processor, etc., using an active copy-cat instance, a.k,a. backup instance, that mirrors operations in the primary instance, but only after those operations have successfully completed in the primary instance. Fault tolerant logic monitors inputs and outputs of the primary instance and gates those inputs to the backup instance once a given input has been processed. The outputs of the backup instance are then compared with the outputs of the primary instance to ensure correct operation. The disclosed embodiments further relate to fault tolerant failover mechanism allowing the backup instance to take over for the primary instance in a fault situation wherein the primary and backup instances are loosely coupled, i.e. they need not be aware that they are operating in a fault tolerant environment. As such, the primary instance need not be specifically designed or programmed to interact with the fault tolerant mechanisms. Instead, the primary instance need only be designed to adhere to specific basic operating guidelines and shut itself down when it cannot do so. By externally controlling the ability of the primary instance to successfully adhere to its operating guidelines, the fault tolerant mechanisms of the disclosed embodiments can recognize error conditions and easily failover from the primary instance to the backup instance.

    Abstract: Fault tolerant operation is disclosed for a primary match server of a financial exchange using an active copy-cat instance, a.k.a. backup match server, that mirrors operations in the primary match server, but only after those operations have successfully completed in the primary instance. Fault tolerant logic monitors inputs and outputs of the primary match server and gates those inputs to the backup match server once a given input has been processed. The outputs of the backup match server are then compared with the outputs of the primary match server to ensure correct operation. The disclosed embodiments further relate to fault tolerant failover mechanism allowing the backup match server to take over for the primary match server in a fault situation wherein the primary and backup match servers are loosely coupled, i.e. they need not be aware that they are operating in a fault tolerant environment. As such, the primary match server need not be specifically designed or programmed to interact with the fault tolerant mechanisms. Instead, the primary match server need only be designed to adhere to specific basic operating guidelines and shut itself down when it cannot do so. By externally controlling the ability of the primary match server to successfully adhere to its operating guidelines, the fault tolerant mechanisms of the disclosed embodiments can recognize error conditions and easily failover from the primary match server to the backup match server.

    Abstract translation: 对于主要匹配服务器，使用活动的copy-cat实例（即备份匹配服务器）来反映容错操作，该活动副本服务器镜像主要匹配服务器中的操作，但仅在主要实例中已成功完成这些操作之后。 容错逻辑监视主要匹配服务器的输入和输出，并且一旦处理了给定的输入，就将这些输入锁定到备份匹配服务器。 然后将备份匹配服务器的输出与主要匹配服务器的输出进行比较，以确保正确的操作。 所公开的实施例还涉及容错故障转移机制，允许备份匹配服务器在主要和备份匹配服务器松耦合的故障情况下接管主要匹配服务器，即，他们不需要意识到它们在 容错环境。 因此，主要匹配服务器不需要特别设计或编程以与容错机制交互。 相反，主要匹配服务器只需要设计为遵守特定的基本操作指南，并在不能这样做时关闭自己。 通过外部控制主要匹配服务器成功遵守其操作指南的能力，所公开实施例的容错机制可以识别错误状况并且容易地从主要匹配服务器故障转移到备份匹配服务器。

Fault tolerant logic monitors inputs and outputs of the primary match server and gates those inputs to the backup match server once a given input has been processed. The outputs of the backup match server are then compared with the outputs of the primary match server to ensure correct operation.

By externally controlling the ability of the primary match server to successfully adhere to its operating guidelines, the fault tolerant mechanisms of the disclosed embodiments can recognize error conditions and easily failover from the primary match server to the backup match server.
