Description

Sometimes a new set of LMP keys will be obtained and copied into an existing KEYS file. If multiple LMP keys exist for the same product and same CPU, but each has a different expiration date, which LMP key is validated on a license check?

Solution

In this case, regardless of the order in which the LMP keys are specified in the KEYS file, the most current LMP key is used.

Take the following sample LMP keys below. The key with DATE(01APR11) is used...

  PROD(X1) DATE(01APR10) CPU(2094-703 /004200) LMPCODE(nnnnnnnnnnnnnnnn) 
  PROD(X1) DATE(01APR11) CPU(2094-703 /004200) LMPCODE(nnnnnnnnnnnnnnnn) 
  where DATE(01APR10) represents April 1st 2010, 
    and DATE(01APR11) represents April 1st 2011
