Enqueue replication server does not terminate after failover

Hi,

We are trying to setup high availability of enqueue server where in we have running enqueue server on node-A and ERS on node-B all the time.

Whenever enqueue is stopped on node-A, it automatically failovers on node-B but after replication of lock table, enqueue does not terminate the ERS running on node-B and as a result our enqueue and ERS both keeps running on the same host (Failover node-B) which should not be the case.

We havenu2019t configured polling in that scenario SAP note-1018968 depicts the same however this is applicable only for version-640 and 700.

Ideally when enqueue server switches to node-B, it should terminate the ERS on the same node after replication and then HA software would take care of its restart on node -A.

We have ERS running of version 701; could anyone please let me know if the same behaviour is common for 701 version as well?

Or there is any additional configuration to be done to make it working.

Thanks in advance.

Cheers !!!

Hi,

Solution to this issue was provided by SAP and ERS is functioning properly in way it should be.

Actually the ERS was getting restarted and not terminated, because of Restart command entry in

the profile START_ERS<nr.>_<hostname>

SAP suggested to replace Restart_Program_00* command with Start_Program_00* in Start profile of ERS instance.

After making above changes everything worked fine in the way it should be.

Thanks to all who provided their valuable feedbacks.

Regards,

Ashish
