Data replication configuration

Hello, I am working on online 7.13 and I would like to monitor data replication. I know system tables sysdri and sysdrcb but I am looking for the place where is stored if data replication is set or not. In fact, onstat -g dri gives the same piece of information if data replication is configured on the instance and down and if DR has never been set up at all for the instance. INFORMIX-OnLine Version 7.13.UC3 -- On-Line -- Up 16:41:01 -- 15088 Kbytes Data Replication: Type State Paired server Last DR CKPT (id/pg) standard off -1 / -1 DRINTERVAL 30 DRTIMEOUT 30 DRAUTO 0 DRLOSTFOUND /users/informix/dump/dr.lostfound Does somebody know how I can identify that the monitored instance has been configured for data replication and that it is down ? Thanks for you help. Jean-Francois.
