Summary: Verify and correct discrepancies between the zOS catalog and the staging DSNs registered in CMNPMAST as allocated.
To better illustrate this discrepancy, consider this example: using CMN/ZMF’s function “query package”, and then asking for “development staging libraries”, you get a list with, say, 14 entries of staging DSNs that, according to CMN/ZMF, have been allocated already (defer = N).
