ERB308I

Explanation
Only the following values for the interval length
are allowed: 1,2,3,4,5,6,10,12,15,20,30,60. This restriction guarantees: That the SYNC value is met every hour
That a Postprocessor report involving several systems (such as
a SYSPLEX report) can be built at least on an hourly basis.

System action
The interval length is changed to the next valid
interval length.

Operator response
None.

System programmer response
Change the interval length to an allowed
value. You might also decide to switch to SYNC(SMF) (see the z/OS RMF User's Guide)
and let the interval length be determined by SMF. This ensures, that
SMF records written by RMF™ and
by other components are written simultaneously.
