尝试使用informix设置复制时出现未知用户错误

我在linux系统上,以informix用户身份登录。我设置了以下环境变量:

INFORMIXDIR=/opt/IBM/informix
INFORMIXSQLHOSTS=/opt/IBM/informix/etc/sqlhosts.mydb
INFORMIXSERVER=rep_0

g_rep_0         group           -               -       i=0
rep_0           onsoctcp        svr0            30100   g=g_rep_0

g_rep_1         group           -               -       i=1
rep_1           olsoctcp        svr1            30101   g=g_rep_1

我正在试着执行命令 cdr define server --init g_rep_0 要将g\u rep\u 0设置为复制主机,但出现以下错误:

connect to rep_0 failed 
Incorrect password or user rep_0 is not known on the database server.
 (-951)
command failed -- unable to connect to server specified  (5)
