Used in: job-definitions.

Contains: name, description, retention-period and job-definition-parameter*.

name

The name of the job definition. The value of this attribute has to be the same as the value of the message selector specified in the JobBean class. It is composed of letters, digits, hyphens (-), and underscores ( _ ) and must have a length of 1 – 230. The job definition is displayed with this name in Job Management in the SAP NetWeaver Administrator.

The description attribute is optional.

Default value: null

retention-period

Determines the default number of days, for which the job logs are persisted in the database.

The possible values are:

●      Positive number (n)

Keep the job for the specified n days.

●      0

Do not keep the job logs

●      -1

Keep the job logs forever.

When you create a scheduler task, you can change the default retention period specified in the job-definition.xml.

Used in: job-definition.

The retention-period attribute is optional.

Default value: 23

job-definition-parameter

This element contains additional information about job parameters.

Used in: job-definition.

Contains: name, data-type, nullable, description, data-default, display, direction, and group.

Used in: job-definition-parameter

The job-definition-parameter element is optional.

name

The name of the parameter. It is composed of letters, digits, hyphens (-), and underscores ( _ ) and must have a length of 1 – 255. The parameter name you specify here has to be the same as the name you specify for the parameter in the JobBean class.

Used in: job-definition-parameter

The name attribute is required.

data-type

The type of data passed by the parameter. The supported data types are: string, float, double, integer, long, Boolean, date, and properties.

Used in: job-definition-parameter

The data-type attribute is required.

direction

Specifies whether the parameter is incoming or outgoing for the job. The following directions are possible:

●      IN

The parameter is passed to the job. The parameter value provides input for the job to process.

●      OUT

The parameter is passed from the job. The parameter value is the job’s output.

●      INOUT

The parameter is passed to the job, the job processes it, and then passes it out.

The values of all parameters from the execution of each job instance are stored in the database. The parameter values from a job execution are not overwritten with the parameter values from successive job executions.

For example, if a job that has OUT parameters runs twice, the values of the OUT parameters for each of the two job executions is persisted. The value of the OUT parameter from the second job execution does not overwrite the value of the OUT parameter from the first job execution.

Used in: job-definition-parameter.

The direction attribute is required.
