Post: Enabling Json API without restarting the cluster

Enabling Json API without restarting the cluster

Hi,

We have a two node cluster and we'd like to enable the Json interface. Is there a way to do that without restarting nodes?

If not, should we update the deployment.xml file and restart one machine at a time or does the entire cluster need to be taken offline and restarted?

Thanks,
Mahmoud

Hi,

Today the only way to enable the json port is by shutting down the Volt cluster and updating the deployment.xml. I opened a feature ticket to add a new sysproc so that it can be enabled from sqlcmd or web studio.

Thanks,
Andy

Thanks. I tried to enable it by shutting down once host at a time but seems like it didn't work.
