STMT_CACHE_NOLIMIT configuration parameter

Use the STMT_CACHE_NOLIMIT configuration parameter to control whether to insert qualified statements into the SQL statement cache.

onconfig.std value
if not present
0 = Prevents statements from being inserted in the cache. The cache can grow beyond the size limit if most of the statements in the cache are currently in use, because the cache cleaning cannot catch up with the insert rate. If you are concerned about memory usage, turn off STMT_CACHE_NOLIMIT to prevent the database server from allocating a large amount of memory for the cache.

1 = Always insert statements in the SQL statement cache regardless of the cache size.
