Define VSAM Files

The Define VSAM File screen lets you create a VSAM file in response to a command of V (Define VSAM File) or D (Delete/Define VSAM File) from the VSAM Utility screen. Use this screen to specify the DSNs for the components of the VSAM file, the VSAM file type, allocation parameters for the data and if applicable, index component, various VSAM file definition parameters, VSAM processing options, and if applicable, SMS Class information.

The DSN for the data and index component defaults to the DSN for the cluster being defined with '.DATA' and '.INDEX' appended, but you can update these names. If the VSAM file being defined does not have an index component, the DSN of the index component is ignored. Only KSDS files and variable-length RRDS files have index components.

IDCAMS control cards are generated according to the parameters typed and then one of the following actions are performed depending on the Execution Mode field in the main VSAM Utility screen.
