Documentation
Definition
This is the number of directory entries allocated for the coupling facility cache structure (DB2 group buffer pool). A directory entry contains control information for one database page. A directory entry is used by the coupling faclity to determine where to send cross-invalidation signals when a page of data is changed or when the directory entry must be reused. This is a shapshot value and is not affected by whether this is an incremental or cumulative display.
