COF005I VLF START IS REJECTED. IEFPARM DD STATEMENT IS MISSING.

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

System action
 The system does not start VLF.

Operator response
 Notify the system programmer.

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