A job in a job chain is a call to a job definition. It may also have an optional precondition function.

The attributes of the job itself are:

  • Job Definition - The name of the job definition or job chain to be called.

If a job definition requires that parameters be specified, or has parameter values that must come from other jobs, then parameter mappings must also be supplied under Input Parameters.

Parameter values can refer to other parameters in the job chain, be set manually, or via an expression.

  • Reference - Allows you to choose which job chain or job chain job parameter value to use for this parameter. The naming works in the following way: {job chain name| step name:job number}:Parameter, for example,

    • ORA_DATALOAD:SID - the value of the job chain level parameter SID of the current job chain called ORA_DATALOAD.

    • DATALOAD:Job 3:SID - the value of the parameter SID of the 3rd job in the DATALOAD step.

  • Expression - the value of the parameter, can be a string, number, character, date time zone, or an expression in Redwood Expression Language.

Preconditions

Jobs have a single, optional precondition function. A job with no precondition always executes. A job with a precondition only executes if the precondition returns true. If the precondition returns false, then the job is skipped.

The default input format for expressions is a string, in preconditions are usually made of functions, function expressions must start with an equals sign (=).

The precondition is an expression in Redwood Expression Language.

Scheduling Parameters

If a job in a job chain requires scheduling parameters to be specified then these parameters must also be set. This window allows for setting job chain job scheduling parameters.

The following scheduling parameters can be set:

  • HoldOnSubmit - expression for hold on submit. Can be true, false (the default), or   =<expression→   which should be a boolean expression.

  • Priority - Number from 1 to 100, the higher the number, the higher the priority.

  • Queue - The name of the default queue.

Note Note

For SAP jobs, the queue defines which SAP instance the job will run against, when the SAP System parameter is not set, SAP jobs require the Queue scheduling parameter or the SAP System parameter be set as there is no default queue for SAP jobs.

End of the note.
