Asynchronous cross-invalidation (XI) for coupling facility (CF) cache structures, e.g. Db2 for z/OS group buffer pools (GBP)

Description of the new feature:

When Db2 in a data sharing environment writes a changed page to the GBP the same page in the buffer pool(s) of the other member(s) must be invalidated to avoid back level data access in this/these member(s). This invalidation is done by the cross invalidation (XI) feature which is a key functionality of data sharing and controlled by coupling facility…
