(UDB only) Size in bytes of the log read buffer.
The Replication Agent for UDB Log Reader component uses the value of the lr_read_buffer_size parameter to determine the maximum number of bytes to be read from the transaction log during each scan. If the read buffer size is too small to read one operation, the Log Reader component shuts down the Replication Agent instance and reports a UDB -2650 or -30081 error. Unfortunately, these UDB error messages cover general communication errors, not just an insufficient buffer size.
A read buffer size that is too large may result in the Replication Agent instance running out of memory.
