安装informix时报错，请路过的大哥大姐进来帮忙看下，谢谢！
你好，我在安装solaris 5.8下安装informix 7.3 时出出了以下错误（以下是online.log文件内容）：其中：onconfig 中的：ROOTPATH /opt/informix/rootdbs rootdbs文件我是直接在/opt/informix/下用touch 命令
创建的一个文件，不知是否可以。麻烦帮忙解答一下，谢谢啦！！！

The chunk '/opt/informix/rootdbs' must have READ/WRITE permissions for owner and group.
這文件要660的權限，屬主/屬組為informix:informix
相信你已經更改過了~~在17：38分這次初始化中已經成功~~
shmget: : key 52564801: shared memory already exists
可能是你的onconfig裏內存分配存在問題，及前面初始化失敗時內存沒有釋放的原因~~ 谢谢各位的解答，我今天早上上班时把服务器重启了一下后oninit -ivy 还是不成功。
明天我再把相关信息贴上来帮我解答下 ：） onconfig 配置：

再执行：oninit 没有报错，再执行:onstat 时出现：

<17 /opt/informix/etc >onstat

请问这是怎么回事？呵呵，以下是online.log文件内容：

oninit -ivy前请先用ipcs检查下是否有informix用户占用了内存段。 按照“ (暗夜星空)”的方法已解决了问题，谢谢各位的回贴解答！~~~
