Enables or disables sending LTL in batch mode.
true
true – Enables sending LTL in batch mode.
false – Disables sending LTL in batch mode.
If the value of the lti_batch_mode parameter is true, the Log Transfer Interface component fits as many LTL commands into its LTL batch buffer as it can before it sends any output to the Replication Server.
The Log Transfer Interface component sends the LTL batch buffer contents to the Replication Server when the time interval specified in the dump_batch_timeout parameter expires, even if its LTL batch buffer is not full.
If the value of the lti_batch_mode parameter is false, the Log Transfer Interface component sends individual LTL commands to the Replication Server for each change set in its input queue.
When Mirror Replication Agent connects to a Replication Server, it determines the version of the Replication Server.
If the Replication Server version is earlier than 12.5, the size of the LTL batch buffer is set to 16K automatically.
If the Replication Server version is 12.5 or later, Mirror Replication Agent sets the size of the LTL batch buffer to the size specified by the ltl_batch_size parameter.
If the Replication Server version is earlier than 12.5 and the value of the lti_batch_mode parameter is true, if any single LTL distribute command exceeds the 16K size of the LTL batch buffer, Replication Server returns an error and it drops its DSI connection with the Mirror Replication Agent.
If the Replication Server version is 12.5 or later, you can use the Mirror Replication Agent ltl_batch_size parameter to set the size of the LTL batch buffer.
In general, setting the value of the lti_batch_mode parameter to true provides better Mirror Replication Agent throughput.
