Installation input validation routine for dynamic allocation
An exit (IEFDB401) from dynamic allocation allows an installation-written routine to validate or alter any DYNALLOC request.
Through IEFDB401, your installation can:
- Control the amount of direct access space requested
- Check for authorization to use specified units
- Check for authorization to use specified data sets
- Check for authorization to hold certain resources for reuse.
