与预期一样,转储文件(dmp)大小约为8MB,跟db 2trc命令中指定的缓冲区大小相符。
As expected, the dump file (DMP) is approximately 8 MB in size, corresponding to the trace buffer size that was specified on the db2trc command.
可以按字节或兆字节来指定缓冲区的大小。
指定不同的缓冲区大小的最好方法是在启动实例之前(也就是在发出db2start命令之前)发出db 2 trc命令。
The best way to specify a different buffer size is to issue the db2trc command before starting the instance (that is, before issuing the db2start command).
另一个问题在于,精确字段仅指定一个参数的最大长度,但是缓冲区需要针对组合起来的数据的最大尺寸调整大小。
Another problem is that precision fields only specify the maximum size of one parameter, but buffers need to be sized for the maximum size of all data combined instead.
实际上,在大多数情况下,您不必花时间决定为缓冲区的数量指定什么值,决定所需的并行度或者缓冲区的大小。
In fact, in most cases, you won't have to spend time deciding what values to specify for the number of buffers, the degree of parallelism you need, or the size of the buffers.
您可以向Buffer引入一个附加参数,用以指定每个内存块的大小,并且可以在抽象缓冲区的初始化期间,将该参数设置为一个可取的值。
You can introduce an additional parameter into Buffer to specify each memory block's size, and you can set it to a preferred value during the initialization of an abstract buffer.
这可以成为又一个可选选项,并且当没有指定该选项时,将使用您更喜欢的值作为缺省的缓冲区大小,就象我对“- l”数字选项所做的那样。
This could become one more optional option, and a default buffer size of whatever value you prefer could be used if this option is not specified, as I've done for the "-l" number option.
审计缓冲区大小(audit _ buf_sz):该参数指定审计数据库时使用的缓冲区的大小。
Audit buffer size (audit_buf_sz) : This parameter specifies the size of the buffer used when auditing the database.
