Documentation
Definition
This is the number of times a directory entry was reclaimed (stolen) and cross-invalidation (XI) signals had to be sent (that is, the stolen directory entry had registered DB2 interest). A high number might indicate a problem. Check the group buffer pool hit ratio to determine if the lack of directory entries might be causing excessive reads from the group buffer pool.
