NUM_PINNED INT Total number of pinned entries.
NUM_COMPILES INT Total number of complete compile requests

NUM_RETRIES INT Number of successful compiles that initially
fail with caching on and that succeed with

NUM_CACHEABLE_
PARSING
INT Total number of SQL statements that mxcmp
has processed after parsing and before
binding of the query and that satisfy the
conditions for cacheability.
NUM_CACHEABLE_
BINDING
INT Total number of SQL statements that mxcmp
has processed after binding and before
transformation of the query and that satisfy
the conditions for cacheability.
NUM_CACHE_HITS_
PARSING
INT Total number of SQL statements that mxcmp
has processed after their parsing and before
their binding and that have produced hits.
NUM_CACHE_HITS_
BINDING
INT Total number of SQL statements that mxcmp
has processed after their binding and before
their transformation and that have produced
hits.
NUM_PIN_HITS_PARSING INT Total number of hits on pinned entries. The
hits occurred after parsing and before
binding.
NUM_PIN_HITS_BINDING INT Total number of hits on pinned entries. The
hits occurred after binding and before
transformation.
