As Enrico recommended, use TSO ISRDDN ENQ
then on panel ISRDENQG, fill in SYSDSN and the data set name:
Major name prefix . . . SYSDSN (SYSDSN, SPFEDIT, etc)
Minor name prefix . . . THE.DATA.SET (dsn etc)
Address id prefix . . . (Job name, User id, etc)
System prefix . . . . . (System name)
Minor name prefix . . . THE.DATA.SET (dsn etc)
Address id prefix . . . (Job name, User id, etc)
System prefix . . . . . (System name)
and press Enter
The list produced will show who has the resource and whether it is SHARED or EXCLUSIVE. SHARED is shown in green and EXCLUSIVE is shown in red.
