SMS
SMS does not allow UNCATALOG without DELETE, therefore the only valid action performed by the scheduler is DELETE.
Depending on the value specified in the SMSMODDELETE parameter of DSTOPTS, the SMS data sets allocated with DISP=(MOD, CATLG, CATLG) are deleted at restart.
All SMS data sets to be processed by EQQCLEAN must have DSNs whose high level qualifier is by default defined as an SMS dataset in the SMS ACS (Automatic Class Selection) rules. EQQCLEAN cannot process as an SMS data set, a dataset whose HLQ is not defined in the ACS rules as an SMS data set, and that is an SMS data set only because of a unit or STORCLASS class override in the JCL.
