Informix HDR implementation on Windows 2012 R2 server - informix

Question

We are implementing HDR (High Availability Data Replication) on Windows 2012 R2 Server.
Steps done:
1) Two new Windows 2012 R2 Servers.
IDS 12.10FC8 installed and created the instance manually using Server Instance
Manager.
Server A details:
DBSERVERNAME: hdr_primary
Host Name: winhdr
IP Address: 199.166.155.195
Port Number: 50005
Server B details:
DBSERVERNAME: hdr_secondary
Host Name: winhdr2
IP Address: 199.166.155.196
Port Number: 50005
2) We have only one instance with one database in Server A (Primary).
No database in Server B (Secondary).
3) We have made changes required for HDR in ONCONFIG, Sqlhosts file on both server.
ONCONFIG parameters Server A:
DBSERVERNAME hdr_primary
ROOTPATH C:\IFMXDATA\hdr_primary\rootdbs_dat.000
ROOTSIZE 204800
DRAUTO 0
DRINTERVAL 0
HDR_TXN_SCOPE FULL_SYNC
DRTIMEOUT 30
ONCONFIG parameters Server B:
DBSERVERNAME hdr_primary
ROOTPATH C:\IFMXDATA\hdr_primary\rootdbs_dat.000
ROOTSIZE 204800
DRAUTO 0
DRINTERVAL 0
HDR_TXN_SCOPE FULL_SYNC
DRTIMEOUT 30
SQL hosts at both servers: placed in %INFORMIXDIR%\etc
hdr_secondary onsoctcp winhdr2 hdrsecport
hdr_primary onsoctcp winhdr hdrpriport
host file at both servers: placed in C:\Windows\System32\drivers\etc
199.166.155.195 winhdr
199.166.155.196 winhdr2
winhdr 199.166.155.195
winhdr2 199.166.155.196
host.equvi file # both servers: placed in C:\Windows\System32\drivers\etc
winhdr informix
winhdr2 informix
services file # both servers: placed in C:\Windows\System32\drivers\etc
hdrpriport 50005/tcp #hdr_primary
hdrsecport 50005/tcp #hdr_secondary
4) After all configuration setting has done we have take ontape backup at
Server A.
Server A status: On-Line
ontape -s -L 0
5) Moved the L0 backup to server B and restored with ontape. Cold restore.
ontape -p
Server B status: Fast Recovery
6) On Server A we had run the below command:
onmode -d primary hdr_secondary
Server A status: On-Line(Prim)
7) On Server B we had run the below command:
onmode -d secondary hdr_primary**
Server B status: Fast Recovery(sec).
Till here we have done.
From here we are facing an issue.
The output at server B of onstat -g dri:
Data Replication at 0000000080CEC030:
Type---------------State-------- Paired server -----------Last DR CKPT (id/pg)

HDR Secondary off hdr_primary -1 / -1 N
DRINTERVAL 0

DRIDXAUTO 1
ENCRYPT_HDR 0
Backlog 0
Nothing Sent
Nothing Received
No Pings
Last log page applied(log id,page): 0,0
Issue: Primary and Secondary are not Paired.
Error in Online log is:
Server A
DR: Trying to connect to secondary server = hdr_secondary
DR: Cannot connect to secondary server
DR: Turned off on primary server
Server B
DR: Trying to connect to primary server = hdr_primary
DR: Cannot connect to primary server
DR: Turned off on secondary server

Answer 1

A good practice to test communication between the two servers, is opening dbaccess -> connect -> and choose the remote server alias.
If you cannot connect through dbaccess, you have a network/communication issue that must be investigated. Open a PMR with IBM support.
Make sure your UPDATABLE_SECONDARY onconfig is set to 0, if you don't have licensed your secondary instance as a read/write, just in case.
