Problem summary
**************************************************************** * USERS AFFECTED: DB2 data sharing users, with table spaces or * * indexes with DSSIZE or PIECESIZE greater * * than 64GB. * **************************************************************** * PROBLEM DESCRIPTION: ABEND04E RC00E2000F in DSNSVSFB, called * * by DSNB5PCO. * **************************************************************** * RECOMMENDATION: * **************************************************************** For table spaces or indexes whose data set size allows page numbers greater than 3 bytes long (4K page size and data set size greater than 64GB, or 8K page size and data set size greater than 128GB), there is a possibility that a castout page list sent in a notify message may be truncated in a way which will cause the storage block trailer to become corrupted when the page list is sorted. This results in an ABEND04E RC00E2000F in DSNSVSFB when the list is freed.
Problem conclusion
The code which sends castout page lists in notify messages has been modified to ensure that the list length is correct for objects with large DSSIZE or PIECESIZE values.
