最近informix 自己down了好幾次，不知道什么原由，Informix已經(jīng)用了好幾年都沒問題了，最近不知道是怎么回事。

開始自己覺得是shm的錯(cuò)，就修改了
onconfig里的
SHMVIRTSIZE    40960          # initial virtual shared memory segment size
SHMADD       40960          # Size of new shared memory segments (Kbytes)
SHMTOTAL       4096000       # Total shared memory (Kbytes). 0=>unlimited
CKPTINTVL    180          # Check point interval (in sec)
加大了1倍。
CKPTINTVL加到了5分鐘

沒什么好奇怪的9.21有幾個(gè)BUG沒有補(bǔ)丁，必須升級(jí)到9.4以后版本。

作者: liaosnet 時(shí)間: 2008-11-06 19:44
日志不全....

作者: hakajawa 時(shí)間: 2008-11-07 21:20
SHMVIRTSIZE 40960 # initial virtual shared memory segment size
改大點(diǎn)

作者: test_123 時(shí)間: 2008-11-09 09:30
謝謝。我把這個(gè)改大了一倍，可還是會(huì)自己down掉。
9.4木有阿。而且這個(gè)Informix用了這么多年了，怎么才會(huì)出bug阿，
要出早該出了阿。
謝謝，還想問問，有informix9.2的補(bǔ)丁頁面么？謝謝，俺找不到阿，謝謝，非常感謝。

作者: happer_xc 時(shí)間: 2008-11-10 17:19
是不是有新的程序使用的消息隊(duì)列，這些消息隊(duì)列與informix有沖突

作者: liaosnet 時(shí)間: 2008-11-10 18:43
額....onstat -g seg有多少個(gè)段?~~??

作者: 大夢(mèng) 時(shí)間: 2008-11-11 16:45
把虛擬段改大點(diǎn)看看!

作者: test_123 時(shí)間: 2008-11-13 11:34
謝謝，改大了一倍，問題依然阿。

把shmvirtsize和shmadd改大些，out of virtul memory可能是v段太多了，你看看onstat -g seg的輸出；

另外，你可以在crontab中定期執(zhí)行onmode -F去釋放那些virtul segment.

ipcs先找出跟informix有關(guān)的share memory segments，然后用ipcrm殺掉再啟動(dòng)。

作者: test_123 時(shí)間: 2008-11-18 08:53
謝謝,切到備機(jī)上去了,可能是share memory 所在共享內(nèi)存段出問題,把數(shù)據(jù)備了,oninit -i吧
