环境: aix5.2 + cics +sybase12<br /><br />启动后发现sybase 和cicsas 会将系统cpu用满,隔一段时间(最多一天)15个cicsas 均起来,cics client 连接失败,但看状态似乎没问题,重起cics后又好。下了cics后系统的资源也随着释放正常。同样的环境还有两台,但均没有这种状况。这台机器的交易量并不大,奇怪为什么出现这个问题,怎么查?先谢了。<br />下面贴个重启不久的topas:<br />Topas Monitor for host: YUXI_A4 EVENTS/QUEUES FILE/TTY<br />Thu Feb 3 12:27:00 2005 Interval: 2 Cswitch 2583 Readch 0<br /> Syscall 7376 Writech 342<br />Kernel 9.5 |### | Reads 14 Rawin 0<br />User 90.5 |########################## | Writes 0 Ttyout 342<br />Wait 0.0 | | Forks 0 Igets 0<br />Idle 0.0 | | Execs 0 Namei 7<br /> Runqueue 3.0 Dirblk 0<br />Network KBPS I-Pack O-Pack KB-In KB-Out Waitqueue 0.0<br />lo0 2377.9 4838.0 4838.0 2377.9 2377.9<br />en0 0.4 1.0 1.0 0.0 0.7 PAGING MEMORY<br />en1 0.0 0.0 0.0 0.0 0.0 Faults 0 Real,MB 1535<br /> Steals 0 % Comp 63.1<br />Disk Busy% KBPS TPS KB-Read KB-Writ PgspIn 0 % Noncomp 34.1<br />hdisk2 0.0 0.0 0.0 0.0 0.0 PgspOut 0 % Client 0.5<br />hdisk1 0.0 0.0 0.0 0.0 0.0 PageIn 0<br />hdisk3 0.0 0.0 0.0 0.0 0.0 PageOut 0 PAGING SPACE<br />hdisk0 0.0 0.0 0.0 0.0 0.0 Sios 0 Size,MB 4096<br />hdisk6 0.0 0.0 0.0 0.0 0.0 % Used 2.4<br />hdisk5 0.0 0.0 0.0 0.0 0.0 NFS (calls/sec) % Free 97.5<br /> ServerV2 0<br />Name PID CPU% PgSp Owner ClientV2 0 Press:<br />dataserve 258194 72.1 4.4 sybase ServerV3 0 "h" for help<br />cicsas 442454 27.5 3.3 cics ClientV3 0 "q" to quit<br />topas 520360 0.5 1.8 root <br />IBM.CSMAg 295060 0.0 2.4 root <br />gil 69666 0.0 0.1 root <br />syncd 139392 0.0 0.6 root <br />i4llmd 262286 0.0 1.2 root <br />rpc.lockd 233694 0.0 0.2 root <br />getty 393416 0.0 0.5 root <br />lrud 45078 0.0 0.1 root <br />rmcd 200848 0.0 2.2 root <br />backupser 184404 0.0 6.0 sybase<br />aixmibd 176258 0.0 0.7 root <br />xmgc 61470 0.0 0.1 root <br />netm 65568 0.0 0.1 root <br />xmfreed 49176 0.0 0.1 root <br />init 1 0.0 0.8 root<br />dced 377030 0.0 2.1 root<br />cics 524342 0.0 2.2 cics<br />cron 196810 0.0 0.6 root<br />inetd 192652 0.0 0.5 root <br />sendmail 82136 0.0 1.0 root <br />dtlogin 143470 0.0 0.6 root <br />errdemon 147672 0.0 0.8 root<br />aioserver 151660 0.0 0.1 root
