STMT_CACHE_HITS hits |
Specifies the number of hits (references) to a
statement before it is fully inserted in the SQL statement cache
Set hits to 1 or more to exclude ad hoc queries from
entering the cache. |
You can only increase or reset the value of STMT_CACHE_HITS.
The new value displays in the #hits field of the onstat
-g ssc output. If hits = 0, the database server
inserts all qualified statements and its memory structures in the
cache. If hits > 0 and the number of times the SQL statement has
been executed is less than STMT_CACHE_HITS, the database server inserts key-only entries
in the cache. It inserts qualified statements in the cache after the
specified number of hits have been made to the statement. ONCONFIG Parameter:
STMT_CACHE_HITS |
STMT_CACHE_NOLIMIT value |
Controls whether statements are inserted in the SQL statement cache. |
If value = 0, the database server inserts
no statements in the cache. If value = 1, the database server
always inserts statements in the cache. If none of the queries are
shared, turn off STMT_CACHE_NOLIMIT to prevent the database server
from allocating a large amount of memory for the cache.ONCONFIG Parameter:
STMT_CACHE_NOLIMIT |
