Apply Windows Patches on NCache Server
Recommended way for applying Windows patches on NCache Server is Windows standard procedure.
Required steps are:
1. Stop Cache
Stop the cache. If this node is part of multiple cache clusters, you need to stop this node/cache from all cache clusters. This will start state transfer process and data will be re-adjusted on 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 now restart NCache Service and also change service start-up type back to “Automatic” for normal usage.
5. Start Cache
Now start the cache manually from NCache Web Manager if auto-start is not enabled. Refresh cache cluster from NCache Web Manager to view this node as active node in the cluster. Furthermore, you can see data being transferred to this lately added cache node by monitoring the cache.
Perform same steps for other nodes in your environment. The main reason of starting NCache service manually is that some of the patches complete their operations after some time of system startup and 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.
