COFVLH05I The ALERTAGE parameter was specified incorrectly.

Explanation
 An update was requested
to CHECK(IBMVLF,VLF_MAXVIRT) which specified             the ALERTAGE
parameter incorrectly.  ALERTAGE should be specified in          
  one of the following forms with at least one pair of class_nameN
                and alert_ageN parameters:             'ALERTAGE(class_name1,alert_age1,class_name2,alert_age2,...)'
'ALERTAGE=(class_name1,alert_age1,class_name2,alert_age2,...)'

                                                                Class
names may be one to seven alphanumeric characters including @, #,
         and $, and may use the standard MVS™ wildcard
characters (* and ?).  If           multiple class_nameN specifications
match for the same class, the last           matching one in the list
will be honored for that class.                          
Class
names may be one to seven alphanumeric characters including @, #,
         and $, and may use the standard MVS wildcard
characters (* and ?).  If           multiple class_nameN specifications
match for the same class, the last           matching one in the list
will be honored for that class.
Alert_ageN is a decimal value
in the range 0 to 99999999 that indicates          an age in seconds.
An alert is issued if an object younger than this             age
is trimmed.  A value of 0 indicates that no trimming alert should
           be issued for this class.  Note that higher values make
it more likely           that an alert will be issued.

System programmer response
 Correct the ALERTAGE parameter. 
Note that alert ages specified                  this way override
the ones in the class definitions in the                       current
COFVLFxx parmlib member and will persist if VLF is               
       stopped and restarted.  A default alert age of 60 is used 
                      when ALERTAGE was not specified in the COFVLFxx
parmlib member                   or via this parameter.  Class names
specified in this parameter that             do not match names defined
in the current COFVLFxx parmlib member are            ignored.
