6.4.1. Enabling Bridge Mode
To enable Bridge Mode, the
--connector-bridge-mode option to
tpm must be set to
tpm configure alpha --connector-bridge-mode=true
The default value is
use the connector in bridge mode.
Bridge Mode can also be used with read-only database servers and
affinity if required.
In addition to enabling and disabling Bridge Mode, the size of the
buffer can also be set by using the
parameters. This configures the size of the buffer used to hold packet
data before the packet is forwarded.
The default size is 262144 bytes (256KB).
A buffer is opened in each direction for each connection made to the
connector when operating in bridge mode.
The total memory allocated can be calculated using the formula:
(connections * (bridgeClientToServerBufferSize + bridgeServerToClientBufferSize)
For example, with the default settings, 20 simultaneous connections will
require 10MB of RAM to service the buffers. With the default connector
heap size the Connector should be able to handle up to 500 simultaneous
