This function returns the size of the value buffer on success and 0 if the name specified is not a valid environment variable name.
如果成功，则此函数返回值缓存的大小，如果指定的名称并不是一个合法的环境变量名，则返回0。
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.
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。
Use the -fd option, which would generate the db2fopt commands required to tell the optimizer to use the specified size rather than calculating based on the buffer pools available for this database.
使用将生成必要的db 2 fopt命令的- fd选项来告诉优化器使用指定大小，而非基于对该数据库可用的缓冲池进行计算。
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.
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。
The db2fopt command tells the optimizer to use the specified value for "buffer pool size," rather than adding up the pages of the buffer pools available.
db 2 fopt命令告诉优化器为“缓冲池大小(Buffer pool size)”使用指定的值，而非将可用缓冲池变量的页面加起来。
