Problem summary
**************************************************************** * USERS AFFECTED: * * Db2 for z/OS V12 users of Real Time * * Statistics * **************************************************************** * PROBLEM DESCRIPTION: * * TOTALROWS in SYSIBM.SYSTABLESPACESTATS * * has negative values. * **************************************************************** * RECOMMENDATION: * * Apply corrective PTF when available * **************************************************************** Internal counters for statistics can overflow into negative values that result in the externalization of incorrect fields such as TOTALROWS.
Problem conclusion
Change internal counters to unsigned integer to allow for values up to 4294967295. SYSIBM.SYSTABLESPACESTATS values for REORGINSERTS,REORGUPDATES, REORGDELETES, STATSINSERTS, STATSUPDATES, and STATSDELETES are unaffected and will continue to have a maximum value of signed integer, 2147483647. The TOTALROWS column is calculated with the updated, unsigned internal counters and may contain a value greater than the sum of the external catalog table values.
