Interface JobLock

    public interface JobLock
extends JobLockComp, UniqueNamedApplicationObject, Readable
    Locks define which jobs can and cannot run together To prevent jobs running concurrently - for example, when two or more jobs need access to the same system resource, such as a tape unit, you can define job locks. A job requests a job lock before the job is able to start; that is, before the job status can change from QUEUED to RUNNING. The job status becomes LOCKWAIT when a lock is already obtained by another job that has the status RUNNING, WAITING or CONSOLE, and the requesting job must wait. The status of the requesting job changes to RUNNING when the other job releases the lock and the requesting job gets the lock. Multiple locks can be defined for a script. Multiple locks can be used to help define which jobs can and cannot run together. For example, you have 3 jobs. Job 1 runs at 02:00. Job 2 and 3 must wait for incoming files and the completion of Job 1. You can define multiple locks on Jobs 2 and 3 so that they run only when the two conditions are met.
