There might not be enough disk space to complete the file write operation, or allocating the buffer could fail if not enough memory is available.

可能没有足够的磁盘空间来完成该文件的写操作，或者由于没有足够的内存可用，分配缓冲区可能失败。

The log buffer acts as a staging area in memory to hold log records instead of having the DB2 UDB engine write each log record directly to disk.

日志缓冲区作为内存中的分级区域（staging area）来保存日志记录，而不是让 DB2 UDB 引擎直接将每条日志记录写入磁盘中。

You'd have to write a handler to build what amounts to an in-memory buffer to keep up with what's already been read; then you'd need some code to read ahead as well.

所以，必须要编写一个相当于内存缓冲器的处理程序来记录已读的内容，也同时需要编写一些代码进行提前读。

Another interesting feature and one that could be a benefit to many computer users is the use of 4 GB of the flash memory to act as a write buffer.
