Apply Windows Patches on NCache Server
The recommended way for applying Windows patches on the NCache Server is Windows standard procedure.
The required steps are:
1. Stop Cache
Stop the cache if this node is a part of multiple cache clusters. You need to stop this node from all the cache clusters. This will start the state transfer process and data will be re-adjusted on the other nodes available in the cluster.
2. Stop NCache Service
Stop NCache Service on this server and also change the service startup type from Automatic to Manual, so that you can manually start NCache Service after reboot.
3. Apply Patch
Apply required patches/updates. Complete all the maintenance tasks running on this machine and then reboot the servers.
4. Restart NCache Service
After successful completion of step 3, restart NCache Service and also change the Service start-up type back to Automatic for normal usage.
5. Start Cache
Now start the cache manually from the NCache Management Center if auto-start is not enabled. Refresh the cache cluster from the NCache Management Center to view this node as an active node in the cluster. Furthermore, you can see data being transferred to this recently added cache node by monitoring the cache.
Perform the same steps for other nodes in your environment. The main reason for starting the NCache Service manually is that some of the patches complete their operations after some time of system startup. It is a good practice to start NCache Service manually once all the patches are fully applied and maintenance work has been completed on your server.
