COF505I DLF START IS REJECTED. IEFPARM DD STATEMENT IS MISSING.

Explanation
 The system rejected the request to start the data
lookaside facility (DLF). The DLF start procedure should include a
DD statement with a DDNAME of IEFPARM, and a DSN parameter that names
the library containing the COFDLFxx parmlib member, but it does not.

System action
 The system does not start DLF.

Operator response
 Notify the system programmer.

System programmer response
 Correct the DLF start procedure by
including a DD statement with a DDNAME of IEFPARM, and an appropriate
DSN parameter.
