DR Problems with 7.30 on Alpha Server
Posted in 1999
Topics: High Availability & Replication, Logging & Checkpoints
Hi,
We are running Informix 7.30 on two Digital Alpha servers (Digital Unix
4.0E).
One is the primary server and the second is the secondary server (the data
replication)
The problem that we're having is once the primary server has done its
complete
cycle of logical log (onstat -l) (12 in our case), then seconsary server
disconnect.
There are the messages on the primary server's logfile
21:04:00 Logical Log 136 Complete.
21:08:06 DR: ping timeout
21:08:06 DR: Receive error
21:08:08 DR: Turned off on primary server
21:08:14 DR: Cannot connect to secondary server
Afterward, no more replication is done, i have to rebuild the data
replication
from a tape or a (big) file. I tried to simply restart the secondary server,
but it stops a the same log number (the last log number of its cycle)
If any of you have suggestions, let me know
Thanks.

You tried restart which way ? What about onmode -d ? What is happened to
primary after replication failure ? Any way, you don't need to restore whole
system on secondary, you can just replay logs with ONDATARTR (if you are
using ONARCHIVE) or ontape from primary. After logs will be replayed,
replicated servers will synchronize automatically.
HTH.
