Managing Jobs

RBMS includes a job scheduler used by the network management applications to run management jobs. A job is a set of tasks that are executed in a specified order.

The task execution flow is defined by the application creating the job. Tasks can be executed sequentially or in parallel. Parallel execution flows can be joined to continue with a single flow. Technically speaking a job is described as state engine. Each task represents a node in the the state engine. The transition between tasks form the execution flow.

The figure below shows a simplified execution flow for a fabric upgrade.

The Pre-Upgrade Check task runs all checks to test whether the fabric can be upgraded. If the fabric passes all checks the execution flow is splitted to run the Spine 1 Upgrade and Spine 2 Upgrade in parallel. The Post-Upgrade Check waits for both upgrades to be completed before it runs the checks to test whether the upgrade was successful. If both switche upgrades were successful the job upgrades the two remaining switches in parallel. Finally another Post-Uograde Check is executed to check whether the upgrade was successful.

An application can program a job task to wait for an explicit confirmation. For example, an operator might want to inspect the state of a switch when a new image has been installed the very first time in the network. The upgrade application can program the first post-upgrade check to wait for confirmation before proceeding with the next upgrade.

The job module is a generic job viewer to inspect the state and progress of scheduled jobs. It also allows to confirm that a job can continue.
