!Configuring the statistics heap STAT_HEAP_SZ
The database configuration parameter STAT_HEAP_SZ determines the maximum amount of memory that will be used when RUNSTATS is performed. This limit applies whether RUNSTATS is issued manually or driven by automatic statistics collection. Although the default value (set when a database is created) is sufficient in many cases, it is usually too low for wide tables (tables with many columns). Whenever a RUNSTATS command fails to complete due to a low setting of STAT_HEAP_SZ, sqlcode SQL0973N is generated. When automatic statistics collection fails to perform RUNSTATS on a table due to insufficient statistics heap memory, the following logpoints will be written to the db2diag.log.\\
