我统计了上面输出的RSS 的总和为1163516（即1136M），那么是否可以说目前我系统中进程的驻留实内存占用了1136M？这个和我实际内存容量有什么关系？
系统资源是：# prtconf -m
Memory Size: 33024 MB
我想查询某进程占用的内存资源。
我查询所有进程的资源占用情况：

我统计了上面输出的RSS 的总和为1163516（即1136M），那么是否可以说目前我系统中进程的驻留实内存占用了1136M？这个和我实际内存容量有什么关系？

1，每一个进程所占实际内存大小，应该还需要减去TRS吧！
-----------------
USER PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND
2，这样的输出格式，是不是ps vx查出来的？
如果是ps vx查出来的话，哪单位应该是k
RSS
（v 标志）进程的实际内存（驻留集）大小（单位是 1KB）。
TRS
（v 标志）文本的驻留集（实际内存）大小。
而ps -ly的RSS单位才是页
RSS (-ly)

这个问题是想查单个进程的内存占用，并没有指明要查informix数据库的进程的内存。不过informix数据库的内存占用可直接使用onstat - 命令，输出的结果中显示内存大小，即是整个数据库的内存大小占用，该内存由所有informix的oninit进程共享，而不存在单个oninit进程占用多少内存之说。
mophis 说的ps aux %MEM查看单进程的内存也可以的。收起

RSS的确代表进程的实际内存，如解析：但是RSS输出的单位是页，一页是 4K 的虚拟内存块，而一帧是 4K 的实内存块。除非另有注释，否则所有的统计信息以 4096 字节的内存页面为单位。所以你1163516应该这么换算，如：1163516*4/1024/1024=4.4G所有进程，应该处理内核进程，目前系统占用了4.4...RSS的确代表进程的实际内存，如解析：
