Optimize Long Performance

Attribute

OptimizeLongPerformance (OLP)

Purpose

Allows the driver to fetch Long data directly into the application’s buffers rather than allocating buffers and making a copy. This option decreases fetch times on Long data; however, it can cause the application to be limited to one active statement per connection.

Valid Values

0 | 1

Behavior

If set to 1 (Enabled), the driver fetches Long data directly into the application’s buffers rather than allocating buffers and making a copy.
If set to 0 (Disabled), the driver does not fetch Long data directly into the application’s buffers.

Notes

*If this option is enabled, the Default Buffer Size for Long/LOB Columns option is ignored.
*This connection option can affect performance.

Default

0 (Disabled)
