Important Parmlib Members

Logical Parmlib members that are particularly important for audit security and control reasons are:

• The linklist members LNKLSTxx and CVSLLAxx
• The APF library members IEAAPFxx and PROGxx
• The appendage member IEAAPP00
• The subsystem member IEFSSNxx
• The SMF member SMFPRMxx.
• The members IEASVCxx, SCHEDxx, and CONSOLxx should also be inspected. These members supply parameters that formerly could be altered only during SYSGEN.
• You should pay close attention to the members COFVLFxx and COFDLFxx that control hyperbatch and hyperspaces.
• If the data center uses DF/SMS, review the member IGDSMSxx because it contains controls for the system managed storage (SMS) facility.
