Property Description
InsensitiveResultSetBufferSize
OPTIONAL
{-1 | 0 | x}
Determines the amount of memory used by the driver to cache insensitive
result set data as follows:
● -1 — The driver caches all insensitive result set data in memory. If the
size of the result set exceeds available memory, an
OutOfMemoryException is generated. Because the need to write result
set data to disk is eliminated, the driver processes the data more
efficiently.
● 0 — The driver caches all insensitive result set data in memory, up to
a maximum of 2 GB. If the size of the result set data exceeds available
memory, the driver pages the result set data to disk. Because result set
data may be written to disk, the driver may have to reformat the data
to write it correctly to disk.
● x, where x is a positive integer — The driver caches all insensitive
result set data in memory, using this value to set the size (in KB) of
the memory buffer for caching insensitive result set data. If the size of
the result set data exceeds the buffer size, the driver pages the result
set data to disk. Because the result set data may be written to disk, the
driver may have to reformat the data to write it correctly to disk.
Specifying a buffer size that is a power of 2 results in more efficient
memory use.
The default is 2048 (KB).
