AUTOMATIC RUNSTATS MIGHT NOT EVALUATE A TABLE IF DATABASE DEACTIVATION OCCURRED WHILE THE TABLE WAS BEING PROCESSED. | |
| Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
| Problembeschreibung: | |
When AUTO_RUNSTATS is enabled for a database, evaluations to
process tables occur periodically. If the database is
deactivated while automatic runstats is processing a table,
automatic runstats might fail to evaluate the table in future
evaluations.
To check if the problem has occurred, run:
SELECT SCHEMA,NAME FROM SYSTOOLS.HMON_ATM_INFO WHERE
STATS_LOCK != 'N';
LIST UTILITIES;
The problem has occurred if:
- the SELECT query returns more than one row, or
- the SELECT query returns one row when LIST UTILITIES does not
show an active Automatic runstats
The problem can occur more frequently on, but is not restricted
to, instances with more than one database enabled for automatic
runstats. | |
