Documentation
Definition
Number of successful requests issued by DB2 to synchronously move a page from the virtual buffer pool to the hiperpool. In other words, this is the number of times that pages are cached in the hiperpool.
Before reusing a buffer in a virtual pool for a page request, its old content needs to be saved in a hiperpool if it is a candidate for hiperpool caching.
