UDYN - Dynamic Dataset Allocation and Deallocation (z/OS only)

This utility program can be used for allocating and deallocating datasets to/from the Com-plete address space without having to restart Com-plete. While UDYN uses the operating system service DYNALLOC, it supports only the following basic parameters of DYNALLOC:

Allocation

  • DD name (required),

  • Disposition (required, only the values “OLD” and “SHR” are supported),

  • Dataset name (required),

  • OPTCD (optional).

Deallocation

  • DD name (required). Any other parameters entered are ignored with the deallocation function.

Upon successful or unsuccessful completion of the operation, the DYNALLOC return code, error code, and information code are displayed, along with a short description text.

Note:
The deallocation function will deallocate any valid DD name entered without further warning. No check is performed whether or not that file might be vital for Com-plete to continue running.
