How Job Management Manager Works › Job Dependencies

Job Dependencies

You can create a Job Management Manager job to run in any of the following three ways:

• Standalone (does not depend on other jobs or involve a prefunction or postfunction)
• Within the constraints of a prefunction and postfunction
• Synchronized to depend on other jobs

  The manager allows a job to have an unlimited number of job dependencies. For example, a primary job can depend on up to 16 other Job Management Manager jobs; each of these jobs can depend on 16 more jobs, and so on. These jobs can be on the same node, within an OpenVMS Cluster, or on remote nodes of a wide area network.

The following diagram illustrates a job dependency hierarchy among several remote nodes of a network:

In the example:

• Job B and Job C depend on Job A. When Job A runs successfully, Job B and Job C can run.
• Job D depends on Job B. When Job B runs successfully, Job D can run.
• Job F depends on Job C. When Job C runs successfully, Job F can run.
• Job E depends on Jobs B and C. Both Job B and Job C must run successfully before Job E can run.
