数据库informix使用的为裸设备

cannot open mcpserver: Permission denied (error=13)

lls -l mcpserver
lrwxrwxrwx   1 root     sys           15 May 10 22:53 mcpserver -> /dev/rdbspace04

裸设备不能访问

裸设备/dbspace/mcpserver没有挂伤上,或者权限不对

it sounds like permission issue -- error 13 ( defiend in  errno.h), also check if /INFORMIXTMP was successfully created.
