Q: Multiple DBserver on one machine

Hy out there, I have a serious problem to bring up a second dbserver an a single machine. Of course I have two slightly different onconfig files, as well as two different environments for each dbserver, but I can't bring them up together. Here is what I did in onconfig: dbservername : dbserv_a dbserv_b servernum: 1 2 rootpath: /dev/server_a /dev/server_b rootoffset: 2 2 /etc/services: online_a 1530/tcp online_a 1530/udp online_b 1531/tcp online_b 1531/udp /usr/informix/etc/sqlhosts: dbserv_a onsoctcp HOST_A online_a dbserv_b onsoctcp HOST_A online_b Normally the dbserv_b is running on HOST_B, but I tried to bring him up on HOST_A (didn't work). Informix always give a warning that I didn't removed some shared memory segments properly ( I don't remember the exact syntax of this error, but that is what is ment) during shared memory initializiation and aborts with fatal error. Any ideas ?? Any help would be appreciated (email preferred) Thanks in advance
