各位高人\r\n\r\n 我们项目的服务器是2G内存的 x86, 上面装了oracle10g , websphere 6.0 , websphere MQ, tomcat--hadson , 可是Oracle 和websphere 启动后都各占了800M左右的内存,导致系统非常的慢,请问这个是为什么,有没有什么解决的办法?\r\n(由于websphere是用root进去的,所以都算在root上了)\r\n\r\n\r\nbash-3.00# prstat -a\r\n PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP\r\n 2545 oracle 685M 517M sleep 59 0 0:00:01 1.7% oracle/11\r\n 1069 root 3968K 1944K sleep 59 0 0:00:15 1.0% prstat/1\r\n 1105 root 830M 555M sleep 59 0 0:01:45 0.9% java/135\r\n 2451 root 72M 15M sleep 59 0 0:00:00 0.4% gnome-panel/1\r\n 2543 root 71M 13M sleep 59 0 0:00:00 0.3% gnome-terminal/2\r\n 2453 root 77M 21M sleep 59 0 0:00:00 0.3% nautilus/6\r\n 693 root 74M 28M sleep 59 0 0:00:14 0.2% Xorg/1\r\n 2517 root 69M 12M sleep 59 0 0:00:00 0.2% wnck-applet/1\r\n 2527 root 66M 9616K sleep 59 0 0:00:00 0.1% mixer_applet2/1\r\n 2525 root 67M 10M sleep 59 0 0:00:00 0.1% gnome-netstatus/1\r\n 2553 oracle 683M 508M sleep 59 0 0:00:00 0.1% oracle/1\r\n 2392 root 72M 15M sleep 59 0 0:00:00 0.1% gnome-session/1\r\n 2447 root 64M 9424K sleep 59 0 0:00:00 0.1% metacity/1\r\n 2511 root 67M 11M sleep 59 0 0:00:00 0.1% clock-applet/1\r\n 2555 oracle 683M 505M sleep 59 0 0:00:00 0.1% oracle/1\r\n NPROC USERNAME SWAP RSS MEMORY TIME CPU\r\n 93 root 886M 759M 38% 0:02:23 4.4%\r\n 42 oracle 863M 797M 40% 0:00:01 2.2%\r\n 28 mqm 197M 123M 6.2% 0:00:00 0.0%\r\n 1 noaccess 88M 101M 5.1% 0:00:10 0.0%\r\n 5 nobody 9524K 2752K 0.1% 0:00:00 0.0%\r\nTotal: 176 processes, 696 lwps, load averages: 0.29, 0.23, 0.19 |
