IEAOPTxx is a PARMLIB member that significantly influences processing by WLM, SRM, and the Supervisor.
To view your active IEAOPTxx parameters, go to RMF Monitor II, select Option L (Program Library and OPT Information), and then choose Option 4. Alternatively, once you are in RMF Monitor II, you can simply type OPT on the command line to display all IEAOPTxx parameters.
From Option L, you can also view the LNKLSTxx, LPALSTxx, and IEAAPFxx lists.
