SYSTEM Replication

[Former Member]

Hi all,

We  are setting up the replication system. I followed the steps on the Hana Admin guide.

The configuration on primary was successful.

When I configuring the dr site and ran the step

/usr/sap/HDB/HDB00/exe/hdbnsutil -sr_register --name=hdbopsdr --remoteHost=hana101.opslab.xxxx.com --remoteInstance=00  --mode=syncmem

I got the below error—

hana101:/usr/sap/HDB/HDB00> /usr/sap/HDB/HDB00/exe/hdbnsutil -sr_register --name=hdbopsdr  --remoteHost=hana101.opslab.ariba.com --remoteInstance=00  --mode=syncmem

adding site ...

checking local nameserver ...

nameserver hana101:30001 not responding.

nameserver is shut down, proceeding ...

collecting information ...

sending registration request to primary site host hana101.opslab.xxxx.com:30001

updating local ini files ...

nameserver hana101:30001 not responding.

done.

How i can solve the above issue ?

Hello Mohammed,

I don't see in your message that you have run sr_enable on the primary.

Please following these good guides step-by-step on how to setup replication.

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/9049e009-b717-3110-ccbd-e14c277d8...

There just a handful of steps and I must honestly say you can't go wrong with the two links I've show you above.

Please follow the procedures from these links and if you still have problems/questions we'll be more than happy to assist you.

Kindest Regards,

Amerjit

Hello Mohammed,

Maybe it is not a issue, please do continue to start up secondary system and monitor if the system replication works fine.

You have stopped the secondary system before registering... So you receive nameserver hana101:30001 not responding.

I also face this warning during registering secondary system:

adding site ...

checking for inactive nameserver ...

nameserver secondary_hostname:3xx01 not responding.

collecting information ...

updating local ini files ...

  done.

Hello Mohammed,

Now what do you see under Overview -> System Replication Status.

Do you have started secondary system with command /usr/sap/hostctrl/exe/sapcontrol -nr xx -function StartSystem HDB
