怎样解决？是不是加大dump　device？怎样加

hanhanhan

systemdumpdev -e 估算DUMP 大小,然后扩DUMPLV为其1.5倍

yiplee

怎么扩？能说清楚点吗？

yiplee

能不能在线扩呢？

solaris+AIX

可以在线扩,smitty chlv

明白了！那DUMP的大小会不会影响系统正常运行呢

用errpt -a -j E87EF1BE 看你的详细信息，一般会告诉你/var/....目录太小，扩大/var即可， 可用dumpcheck -v 检查是不是符合要求了！

Starting with AIX 5.x, the dumpcheck facility will notify you if your dump device needs to be larger, or the file system containing the copy directory is too small.

一般默认的dump设备是hd6,你的hd6不小于内存大小就不会报这个错误了

谢谢了！我已经加大ＤＵＭＰＬＶ．
也不是系统的问题．是数据库操作前台性能减慢，使用户登陆查询边慢

Largest dump device size in kb 1048576 <---

This is the size of the dump device.

Current estimated dump size in kb 1062912 <---

And this is the estimated size of the dump in kb if you system were to crash
under your current load.

You just need to

Depending on your PP size to make lg_dumplv big enough to house 1062912 KB
