Linux will use all memmory for filesystem caching. It will put commonly used files in RAM to offload on disk i/o Run the following command free -m Look at the free column on the +/- buffers line for your true free ram minus the RAM for disk caching Mike On Tue, Jul 22, 2008 at 6:08 AM, sunhux G <sunhux@xxxxxxxxx> wrote: > Hi, > > Is there a way to run "top" such that it sorts by memory > usage as "free -m" showed very little memory left (3.4Mb) > ever since the outsourced developer installed Oracle sso. > > The following is the top output currently : > > top - 18:04:17 up 19 days, 5 min, 3 users, load average: 0.27, 1.43, 2.03 > Tasks: 281 total, 1 running, 280 sleeping, 0 stopped, 0 zombie > Cpu(s): 0.3% us, 2.1% sy, 0.0% ni, 97.5% id, 0.1% wa, 0.0% hi, 0.0% > si > Mem: 8308576k total, 8273688k used, 34888k free, 66240k buffers > Swap: 8385888k total, 294672k used, 8091216k free, 6814264k cached > > PID USER PR NI %CPU TIME+ %MEM VIRT RES SHR S COMMAND > 8775 oracle 17 0 5 31:44.15 0.1 43472 6140 4328 S tnslsnr > 12570 oracle 16 0 4 772:20.25 0.1 199m 6900 4180 S opmn > 4961 root 16 0 0 0:00.18 0.0 2492 1128 780 R top > 16500 oracle 16 0 0 0:10.72 0.2 606m 17m 15m S oracle > 1 root 16 0 0 0:29.11 0.0 2136 504 432 S init > 2 root RT 0 0 3:20.59 0.0 0 0 0 S migration/0 > > How would you approach it to find out if there's memory leakage? > > > Thanks > U > -- > redhat-list mailing list > unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe > https://www.redhat.com/mailman/listinfo/redhat-list > -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
