Rational Developer for System z

Allocating VSAM data sets

The Allocate VSAM Data Set wizard offers the ability to allocate VSAM data sets in the Remote Systems view.

About this task

This topic describes how to use the VSAM allocation function available in the z/OS® Integrated Development Environment (zIDE) when the Rational® Developer for System z® client and server are both at version 8.0.3 or later. For versions prior to 8.0.3, the same function is available through File Manager Integration, which is deprecated in version 8.0.3. The function of VSAM allocation and the response you might see when you request this function vary according to the version of Rational Developer for System z installed and the status of File Manager on the z/OS system:
Table 1.

Prior to 8.0.3 Inactive Warning message is displayed.
