MVS Data Set Attributes

Use this wizard to configure MVS data set attributes FTP will use when creating data sets. This wizard is available both when configuring FTP clients and FTP servers. The settings are applicable to clients when creating data sets on the client's system. The settings are applicable to servers when creating data sets on the server's system.

An FTP user can modify these settings using the LOCSITE and SITE commands, but the modifications apply to only that user's session.

Before you begin, decide whether to obtain settings from an existing data set, or from any Storage Management Subsystem (SMS) classes. You have the option of individually specifying data set attributes, inheriting attributes from an existing model data set, or obtaining attributes from SMS class definitions.

For example, the Logical Record Length (LRECL) attribute can be obtained from an SMS data class, from an existing model data set, or set individually.

Since you can specify SMS classes, a model data set, and individual attribute settings, the following list shows the policy used to determine an attribute value. The list is order of precedence:

  1. Any individual attribute settings.
  2. Any model data set settings.
  3. Any management class settings.
  4. Any data class or storage class settings.

Attributes obtained from model data set:

Data class attributes that can be overridden:

Management class attributes that can be overridden:

Storage class usage

When using a storage class, the values for volume, unit name, and unit count are obtained from the storage class.

Steps

  1. If you want to inherit attributes from an existing model data set, click "I want to use a model data set (DCBDSN)" and enter the model's fully qualified data set name.
  2. If you want to obtain attributes from SMS classes, click "I want SMS to control one or more attributes", and:
    1. If you want to obtain attributes from an SMS data class, enter the data class name.
    2. If you want to obtain attributes from an SMS management class, enter the management class name.
    3. If you want to obtain attributes from an SMS storage class, enter the storage class name.
  3. Click the "Next" button to proceed to the next panel.

You have completed this panel after optionally entering the fully-qualified model data set name and optionally entering SMS class names.
