Re: Data Replication

Hi, Sorry for late reply. I am using 7.11UC2. We are testing replication. It is DHR. And asysnchronous mode. - I was trying to test if primary goes down, whether I can use seconadry as a standard server and when primary is up, whether I can change seconadry-which was standard to seconadry. So when REPLICATION WAS WORKING, I shutdown PRIMARY, made seconadry as standard server. using onmode -d standard command.And :-)) It could not change mode to standard mode. Probs : Seconadry could not change mode to ONLINE fm RECOVERY MODE !!! I tried to take it to offline mode and then tried to bring it up, It did not work. It remained in the recovery mode. On the other side when we tried to bring up primary, we could not. Following is the msg from msg log file. *********************************************************************** 18:36:09 DR: DRAUTO is 0 (Off) 18:36:15 INFORMIX-OnLine Initialized -- Shared Memory Initialized. 18:36:15 DR: Trying to connect to secondary server ... 18:36:16 DR: Primary server connected 18:36:17 DR: Server type incompatible 18:36:17 rshdr.c, line 3344, thread 23, proc id 3232, DR: Server typeincompati ble. 18:36:17 PANIC: Attempting to bring system down **************************************************************************** I tried ------------- Begin Original Message ------------- From: attmail!internet!rmy.emory.edu!informix-list-owner (Juan R.

I have 7.11UC1 and it has a bug. When you try to bring up the secondary (from scheduled downtie or not) it won't find the checkpoint in the log log and so it stays in recovery mode. I would be very interested in hearing your feedback on how it goes because I'm thinkg of doing the same (DR is local now). thanks,
