Patent ID: 8799926

Claim:
One or more non-transitory computer-readable media having computer-executable instructions embodied thereon for performing a method of discovering whether an individual queue manager is currently active in a failover environment that includes at least two computing devices and a data store that is accessible to the at least two computing devices, the method comprising: for each queue manager installed on a computing device, identifying a file directory associated with the queue manager, wherein each queue manager is associated with a respective file directory; discovering whether an individual queue manager is currently active in a failover environment by determining whether said each queue manager has access to a core configuration file through the respective file directory associated with said each queue manager, wherein each queue manager accesses the core configuration file through the respective file directory when the core configuration file is mapped to the respective file directory, and wherein the core configuration file is mapped to the respective file directory when the queue manager is active and the core configuration file is not mapped to the respective file directory when the queue manager is inactive; and communicating an instruction to monitor the each queue manager associated with the file directory determined to have access to the core configuration file.
