Automatic statistics collection logs excessive messages to db2diag log files | |

Problem description: | |
During automatic statistics collection, diagnostic information can be logged to the db2diag log. In some situations, log entries are incorrectly indicated as Error level when they should be indicated as Warning level. In other situations, the log entries should be logged to the optstats log instead of the db2diag log. Automatic statistics collection is controlled by the AUTO_RUNSTATS and AUTO_STMT_STMTS database configuration parameters. For example, the following error is logged to the db2diag log when automatic statistics collection tries to process a table scheduled for asynchronous runstats, but the table can no longer be found because it has been dropped. 2010-09-21-13.40.25.393781-240 I267916A578 LEVEL: Error PID : 9711862 TID : 1029 PROC : db2acd INSTANCE: sahanant NODE : 000 APPID : *LOCAL.sahanant.100921174026 EDUID : 1029 EDUNAME: db2acd FUNCTION: DB2 UDB, Automatic Table Maintenance, atmRefreshInfoTable, probe:390 DATA #1 : String, 11 bytes AutoStats: DATA #2 : String, 145 bytes [IBM][CLI Driver][DB2/AIX64] SQL0100W No row was found for FETCH, UPDATE or DELETE; or the result of a query is an empty table.
