Active node detection in a failover computing environment

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon for performing a method of determining whether a program that is installed on a computing device is active, the method comprising:

• identifying a file directory associated with a backup queue manager that is one of a plurality of programs installed on the computing device, wherein the program is part of a failover cluster that includes at least one pair of programs that are capable of performing the same functions, wherein the at least one pair of programs includes the backup program installed on the computing device and a primary queue manager installed on a different computing device, wherein the primary queue manager is associated with a first file directory and the backup queue manager is associated with a second file directory, wherein the backup queue manager becomes active only when the primary queue manager fails, and wherein the at least one pair of programs requires access to a common configuration object located in a data store to operate;
• determining whether the backup queue manager is active by determining whether the common configuration object is mounted to the second file directory associated with the backup queue manager,
• A) wherein when the common configuration object is mounted to the second file directory, then the backup queue manager currently has access through the second file directory to the common configuration object, and the backup queue manager is determined to be active, and
• B) wherein when the common configuration object is not mounted to the second file directory, then the backup queue manager currently does not have access through the second file directory to the common configuration object, and the backup queue manager is determined to be inactive;
• upon determining that the common configuration object is not mounted to the second file directory associated with the backup queue manager, wherein the backup queue manager does not currently have access through the second file directory to the common configuration object, and wherein the backup queue manager is determined to be inactive, then storing a record that indicates the backup queue manager should not be monitored.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon for performing a method of determining whether a queue manager in a clustered failover environment is active, the method comprising:

• identifying the queue manager installed on a first computing device, wherein the queue manager is part of a failover cluster that includes at least one pair of queue managers capable of performing the same functions, wherein the at least one pair of queue managers includes the queue manager and a backup queue manager installed on a second computing device, wherein the queue manager and the backup queue manager are each associated with a respective file directory, wherein the backup queue manager is configured to take over the functions of the queue manager when the queue manager fails, wherein each of the queue manager and the backup queue manager requires access to a common core configuration file located in a data store to operate, and wherein each of the queue manager and the backup queue manager accesses the common core configuration file through the respective file directory when the common core configuration file is mapped to the respective file directory;
• determining that one of the queue manager and the backup queue manager is inactive by determining that the common core configuration file is not mapped to the respective file directory associated with the one of the queue manager and the backup queue manager, wherein the one of the queue manager and the backup queue manager does not have access to the common core configuration file through the respective file directory;
• and
• based on the determination that the one of the queue manager and the backup queue manager is inactive, then storing a record that indicates the inactive one of the queue manager and the backup queue manager should not be monitored.
