oninit时错误：Fatal error in shared memory creation

builder

有两个数据库服务器，分别是member和settle，当member启动后
再启动settle时则出现Fatal error in shared memory creation
的错误。

是sco 5.06上的online 7.31。

相关文件如下：
//-- onconfig.settle
DBSERVERNAME     settle
DBSERVERALIASES  stl_tcp
NETTYPE          ipcshm,1,30,CPU
NETTYPE          tlitcp,1,30,NET

//-- /usr/informix/etc/sqlhosts
member    onipcshm    on_hostname    on_servername
demo_se   seipcpip    se_hostname    sqlexec
settle    onipcshm    test3          sqlsettle
stl_tcp   ontlitcp    test3          sqlstltcp

帮帮偶吧，ft

看一下关于多重驻留的！
检查一下你onconfig中的SERVERNUM，不能重复！

builder

需要任何配置文件，都可以提供，请诸位帮助

我的机子一共有个onconfig文件分别是onconfig, onconfig.std, onconfig.member, onconfig.settle；除了前面两个文件的SERVERNUM都是0之外，其他都不是重复的阿，请指教~

大梦

SERVERNUM一个用1，一个用2,
总之不能重复！

就是这个问题！

    这样阿，是不是要把onconfig.std和onconfig文件中的SERVERNUM设成不同的呢？我明天回单位试试，另外还有没有其他什么地方要修改SERVERNUM的？

我发现online.log文件中有段提示是关于“内存段已经存在”的

启动不同的Server需要不同的环境变量，我估计你是这方面的问题。
关于多驻存的配置，估计你已经可以完成了，主要不同的空间、不同的端口、不同的ServerName、不同的Onconfig文件等。
启动第一个Server时，比如onconfig文件是onconfig.member，ServerName是member，可以这样：
INFORMIXSERVER=member
ONCONFIG=onconfig.member
export INFORMIXSERVER ONCONFIG
oninit
继续启动第二个Server时，比如onconfig文件是onconfig.settle，ServerName是settle，可以这样：
INFORMIXSERVER=settle
ONCONFIG=onconfig.settle
export INFORMIXSERVER ONCONFIG
oninit
可以继续第三个、第四个...
其它的环境变量应该没有变化（关于环境变量的设置应该依据不同的shell进行）。
