sort file size mysql设置

On AIX 5.2 or later If the heap size is 3 GB or greater, LDR_CNTRL=MAXDATA=0@DSA is set. If the heap size is between 2.3 GB and 3 GB, LDR_CNTR=MAXDATA=0XB0000000@DSA is set. If the heap size is less than 2.3 GB, LDR_CNTR=MAXDATA=0XA0000000@DSA is set. 也就是说如果在系统里设置了LDR_CNTRL=MAXDATA=0@DSA 那么就可以用到3G以上内存了. On AIX 5.1 Although the very large address-space model is also ...

请教几个问题: 1,好象安装时没有Logical page size设置? 这一值是SYBASE使用的最小数据单位?安装完可以更改吗?在哪里可以看到此值? 2,如果进行SYBASE在不同主机(均为SOLARIS系统)的DUMP和LOAD, 两机的SYBASE的Logical page size是不是必须一样? 不胜感谢!

Recap: this information can be useful if you’re looking for a good innodb_log_file_size value, such that will not pose too much I/O (smaller values will make for more frequent flushes), not will make for a too long recovery time (larger values mean more transactions to recover upon crash). It is assumed that the 60 seconds period represents an average system load, not some activity spike period....

根据mysql手册上说,Key_reads/Key_read_requests 比例应该接近于0.01甚至越小越好,Key_writes/Key_write_requests 则为1,这样说明key_buffer_size设置比较恰当,我现在设置的key_buffer_size为768m,可那两项比例一个为1:30,1:2,我应该是把key_buffer_size调整的更大还是更小呢,谢谢

int _tmain(int argc, _TCHAR* argv[]) { SYSTEM_INFO siSysInfo; GetSystemInfo(&siSysInfo); printf("current OS Page size: %u \n",siSysInfo.dwPagesize); return siSysInfo.dwPagesize; } 我用这个函数得出来的页面文件大小为什么和我在界面上(点开电脑属性-advanced-performance-settings-advanced)看到的不一样呢?

cooked file 文件的权限设置是不是如下: -rwxr-x--- informix informix cookedfile11 或者是 -rwxrwx--- informix informix cookedfile11 而我见到的客户机器内是 -rwxrwxrwx informix informix cookedfile11 这样好像不对吧?岂不是很危险吗! 还请各位指教。
