CROSS_INVALLIST: Invalidating a List of Data Items

You may want to perform a cross-invalidate operation on a list of entries with one operation. The CROSS_INVALLIST request allows you to cross-invalidate up to 4096 entries at one time. The result of the cross-invalidate operation is that with the exception of the connection specified by CONTOKEN, all connections with registered interest in the specified entries will have interest deregistered and a cross-invalidate performed against their local caches.

The CROSS_INVALLIST request type is valid only for a structure allocated in a coupling facility with CFLEVEL=12 or higher.
