Clearly, all three solutions present limitations and the conventional buffer memory management approach is not a good mechanism for coding large-scale interacting software.

显而易见地，这三种解决办法全都存在局限性，因此传统缓冲区内存管理方法并不是适合编写大规模交互软件代码的机制。

What essentially we can get away with is that log buffer located in database shared memory is the mechanism provided to ensure each transaction is logged to log files.

注意，日志缓冲区位于数据库的共享内存中，这种机制确保每个事务被记录到日志文件中。
