Informix HDR Replication

Currently I am using Informix HDR on a test environment. The current informix Version running on this platform is 9.4uc3 running on Linux Advanced server 3.0. I am being faced with a problem, which isn't constant. The prob is as follows: Fst Prob.) I have a pair of informix environments replicating each other. When I am shutting down the primary server with onmode -ky, and changing the mode of the secondary server (to simulate a changing process) with onmode -d standard, the secondary server halts into a checkpoint required and never comes up into standard mode. While I had other instances, were the secondary server changed into standard mode without any probs.! Sec. prob) When trying to change the secondary server to standard server mode, while the primary is still online, it reports to view the log file and never changes to standard mode! Is there any sequence that I have to follow when changing the secondary to standard, should I wait for the onstat -m to report that the Primary server connection have been lost and afterwards change to standard mode? Thanks for your help Robert

Can you give us the stack of onmode_monitor thread when server is hanging during state change (off-secondary to standard). onstat -g dri output will also be useful. When DR is on, you can not switch secondary server to standard mode. To bring the server to standard mode, you need to switch off the DR first. To do this make primary standard first and then make secondary as standard. -Ajay Gupta
