Apply Private Patches
We'll guide you on how to apply private NCache patches to address specific bugs in NCache and provide essential information about reaching out to our support team if you encounter any issues.
Additionally, when applying NCache patches, it is essential to stop all caches and NCache processes running on a specific node to avoid any issues. By stopping all caches on the node, it gracefully leaves the cluster and helps maintain data integrity.
Note
You should always do a maintenance, patching, or upgrading activity one node at a time.
Steps To Apply NCache Private Patches
To apply an NCache patch, simply follow the steps provided by Alachisoft Support Team. They will share the necessary instructions and files for applying the patch to your existing NCache installation.
The required steps are:
1. Stop Cache
Stop the cache on a particular server node, 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 NCache 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 on a particular server node, if this node is a part of multiple cache clusters through NCache Management Centre, if auto-start is not enabled. [You can skip this step if auto-start is already enabled].
Refresh cache cluster from NCache Management Centre 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 the same steps for other nodes in your environment. 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.
