5.1.3 Reserved Words <strong>for</strong> Use in Predecessors<br />

This topic discusses reserved words that are used to define predecessor<br />

conditions. These reserved words ensure predecessor conditions are upheld,<br />

but do not cause any <strong>for</strong>m of selection.<br />

PRED<br />

NJE<br />

DOS<br />

DSN<br />

GDG<br />

GBLxnn<br />

Or PRED SCD indicates the predecessor job or schedule must<br />

complete, probably on a prior day. That is, the predecessor must<br />

complete some time since the job or schedule last ran. If the PRED<br />

schedule or job is also in today's workload, it will always wait <strong>for</strong><br />

today's PRED.<br />

Indicates the predecessor job runs on another node. NJE can be<br />

prefixed with START indicating that this job will not start until the<br />

NJE job that is the predecessor also starts. It can also be prefixed<br />

with PRED indicating the predecessor was an NJE job that ran on a<br />

prior day.<br />

Indicates the predecessor job is a nonscheduled <strong>VSE</strong> job. DOS can<br />

be prefixed with PRED indicating it was run on a prior day.<br />

Indicates the predecessor is the close of an output data set. DSN can<br />

be prefixed with PRED indicating the output data set was closed on<br />

a prior day.<br />

Indicates the predecessor is the close of an output generation data<br />

group. GDG can be prefixed with PRED indicating the output<br />

generation data group was closed on a prior day.<br />

Indicates a user-defined event must be satisfied. These<br />

predecessors are called global parameters and are described in the<br />

topic Commonly Asked Questions in the chapter "Tips."<br />

When predecessors are defined this way, they are called explicit predecessors.<br />

That is, the predecessor name is explicitly stated in the criteria. This particular<br />

type can even be further qualified as a keyword-defined explicit predecessor.<br />

The following examples illustrate the use of predecessor reserved words. Each<br />

of these examples is called a condition.<br />

Example<br />

JOB1<br />

START JOB1<br />

PRED JOB1<br />

Interpretation Of Predecessors<br />

Do not run until after JOB1 completes.<br />

Do not run until after JOB1 starts.<br />

Do not run unless JOB1 completed at least once<br />

since the last time the job you are defining<br />

predecessors <strong>for</strong> ran. If JOB1 happens to be in<br />

today's workload, this job will not run until today's<br />

JOB1 completes regardless of when JOB1 ran<br />

previously.<br />
