Error description
This may be due to RUNSTATS .. INDEXSAMPLE, Real-Time Statistics (RTS) running with index sampling or AUTO_RUNSTATS running with index sampling. All index statistics sourced from catalog tables are accurate and unaffected. Inaccurate index statistics could be returned by MON_GET_INDEX and RTS statistics fabrication. Non-fabricated/fully collected RTS statistics are not affected. An example of MON_GET_INDEX providing a different NLEAF count relative to that seen in SYSCAT.INDEXES after a RUNSTATS with INDEXSAMPLE: RUNSTATS ON TABLE DB2INST1.TEST AND INDEXES ALL INDEXSAMPLE SYSTEM(10) DB20000I The RUNSTATS command completed successfully. SELECT NLEAF FROM TABLE(MON_GET_INDEX('DB2INST1','TEST',-1)) NLEAF -------------------- 24 1 record(s) selected. SELECT NLEAF FROM SYSCAT.INDEXES WHERE TABNAME='TEST' NLEAF -------------------- 250 1 record(s) selected.
Local fix
Avoid use of RUNSTATS with the INDEXSAMPLE clause. Disable Auto Sampling using the database config parameters, AUTO_SAMPLING.
