Effective buffer control technique using multiple level buffer and Tx buffer flush in bluetooth systemPURPOSE: A method for effectively managing the buffer through a multi-stage buffer and a transmission buffer in a bluetooth system is provided to transmit data at 1:N connection through the re-...
sync_binlog是将二进制日志文件刷新到磁盘上。 innodb事务日志redo log,binlog逻辑过程如下: 事务写入redo log buffer中; 将redo log buffer刷新到redo log中,不过会先写一个TX PREPARE标记; 写binlog 在redo log中写入TX COMMIT标记; 将写binlog成功的标记写入redo log。 1. 事务日志写盘配置 参数解析如下: ...
Connecting wires Hardware Connection Connect the pins on the UBlox Neo-6M GPS module to the pins on your USB to UART module. The connections are: VCC - +5V RX - TXO TX - RXI GND - GND Connect the GPS antenna to the GPS module. Connect the USB to UART module to the host computer ...

如果你在ADDM(?/rdbms/admin/addmrpt)中找到上述文字,那么基本可以确认gc buffer busy的源头是log file sync(虽然本质上不是),那么优先解决log file sync的问题; log file sync 当然有少数的bug存在,但更多的是存储、板卡、链路等硬件因素造成的。解决了log file sync后,那么gc buffer busy往往也就解决了。

调用方不得在此调用后将任何进一步PD_BUFFER结构发布到队列。 此例程的主要用例是刷新接收队列 -- 如果没有传入流量,则发布的缓冲区将无限期地位于接收队列中,需要先刷新这些缓冲区,然后才能关闭队列。 实际上,传输队列不存在相同的问题,因为传输请求不会无限期地存在。 但是,提供程序必须接受传输队列的刷新调用, (...
