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…Continue
