Automatic dynamic allocation z/OS DFSORT Application Programming Guide SC23-6878-00 |
|
Your system programmer has set the DYNAUTO installation option to control whether dynamic allocation is used automatically, or only when requested by the DYNALLOC run-time option. DYNAUTO also controls whether dynamic allocation or JCL allocation takes precedence when JCL work data sets are specified. If your system programmer selected DYNAUTO=IGNWKDD, dynamic allocation takes precedence over JCL allocation (JCL work data sets are actually deallocated). If you want the opposite precedence for selected applications, use the run-time option USEWKDD. If your system programmer selected DYNAUTO=YES, JCL allocation takes precedence over dynamic allocation. If you want the opposite precedence, you must remove the JCL allocation statements. If your system programmer selected DYNAUTO=NO, dynamic allocation of work data sets is not used unless you specify the DYNALLOC run-time option. JCL allocation takes precedence over dynamic allocation. |
