Initialization Parameters, 149 of 220
PARALLEL_EXECUTION_MESSAGE_SIZE
specifies the size of messages for parallel execution (formerly referred to as parallel query, PDML, Parallel Recovery, replication).
On most platforms, the default value is 2148
bytes if PARALLEL_AUTOMATIC_TUNING
is set to false
, and 4096
bytes if PARALLEL_AUTOMATIC_TUNING
is set to true
. The default value is adequate for most applications. Larger values require a larger shared pool. Larger values result in better performance at the cost of higher memory use. For this reason, replication gets no benefit from increasing the size.
