我現(xiàn)在發(fā)現(xiàn)我們的系統(tǒng)內(nèi)存使用已經(jīng)百分之百了。\r\n我想知道都是哪些進(jìn)程占用了我們的內(nèi)存。\r\n于是我通過svmon -Pt 100查看前100個占用內(nèi)存的進(jìn)程。\r\n通過這個命令形成的日志，發(fā)現(xiàn)前幾個進(jìn)程的內(nèi)存使用就已經(jīng)超過了我們的總內(nèi)存了。\r\n感覺有點不對。\r\n-------------------------------------------------------------------------------\r\n Pid Command Inuse Pin Pgsp Virtual 64-bit Mthrd 16MB\r\n 791176 oracle 1239650 66896 3833 1233387 Y N N\r\n\r\n PageSize Inuse Pin Pgsp Virtual\r\n s 4 KB 1142610 0 2601 1132251\r\n m 64 KB 1969 85 77 2225\r\n\r\n Vsid Esid Type Description PSize Inuse Pin Pgsp Virtual\r\n 0 0 work kernel segment (lgpg_vsid=0) L 16 16 0 16 \r\n 909a8 7000000e work default shmat/mmap s 65536 0 0 65536 \r\n 56584 70000008 work default shmat/mmap s 65520 0 0 65520 \r\n 1f4c3e 70000006 work default shmat/mmap s 65520 0 0 65520 \r\n b374a 70000004 work default shmat/mmap s 65520 0 0 65520 \r\n f0a0e 7000000b work default shmat/mmap s 65520 0 0 65520 \r\n 1f08de 70000009 work default shmat/mmap s 65520 0 0 65520 \r\n 1028b1 70000007 work default shmat/mmap s 65520 0 0 65520 \r\n 1e6c3f 70000002 work default shmat/mmap s 65520 0 0 65520 \r\n 172996 7000000a work default shmat/mmap s 65520 0 0 65520 \r\n 628c7 70000003 work default shmat/mmap s 65520 0 0 65520 \r\n 629a7 7000000c work default shmat/mmap s 65520 0 0 65520 \r\n 1d175c 70000005 work default shmat/mmap s 65520 0 0 65520 \r\n 76746 70000001 work default shmat/mmap s 65503 0 0 65503 \r\n e444f 11 work text data BSS heap s 64953 0 0 64953 \r\n 1869f9 7000000d work default shmat/mmap s 61433 0 0 61433 \r\n 146b55 7000000f work default shmat/mmap s 59416 0 0 59416 \r\n 26b63 12 work text data BSS heap s 52587 0 0 52587 \r\n 1b6cfa 70000010 work default shmat/mmap s 37510 0 0 37510 \r\n 1070b0 90000000 work shared library text m 1964 82 77 2220 \r\n 80989 10 clnt text data BSS heap, s 11931 0 -
