Reactivate NCache License

NCache License needs to be reactivated on an already activated machine in the following cases:

Logical Processor or RAM Change:

In case you increase the number of logical processors (on an activated machine) or your memory increases to a number where the requirement for an additional license becomes valid, you need to reactivate your license. If you don't reactivate, the caches will stop.

Change in the Number of Client Licenses:

In case there is an increase/decrease in the number of clients against the Client Server license, you need to reactivate your license. If you don't reactivate, the caches will stop.

License Period Expiry:

In case of Subscription based licensing, the customer is notified 60 days before the license period ends. NCache provides an auto-renewal feature for the license which will check for any next subscription so that the user gets his/her license reactivated for the next period (i.e. the next year after license expiration) automatically.

Auto-renewal is ON by default and is tried by NCache service on all cache servers 30 days before the license expiration.

If the user no more wants to continue using same machine in the next subscription period, he/she can manually turn off the auto-renewal. In order to disable auto-renewal, set the auto-renewal flag FALSE in service configuration file found in NCache installations as follows:

.NET: Alachisoft.NCache.Service.exe.config located in %NCHOME%/bin/service
.NET Core Windows: Alachisoft.NCache.Service.dll.config located in %NCHOME%/bin/service
.NET Core Linux: Alachisoft.NCache.Daemon.dll.config located in /opt/ncache/bin/service

The following configuration switches off auto-renewal of license for your machine:

<add key="NCacheServer.AutoRenewal" value="False"/>

After this you need to restart NCache Service.

In case of manual activation or if auto-renewal is disabled, the user gets WARNING messages in Event Logs.

Note

Auto renewal starts 30 days before expiry.
Manual renewal can be done at any time.

If the request for auto-renewal fails after the grace period ends, the user needs to manually activate NCache for the next period. In order to renew the license:

Purchase a new license period against same license key. Contact Alachisoft Sales for this.
Once new license period is purchased, activate your machines using Register-NCache PowerShell cmdlet.

PowerShell Reactivation

You can reactivate your license using the license key obtained from Alachisoft. NCache provides Register-NCache PowerShell cmdlet to reactivate your license. NCache provides two reactivation modes, online and offline.

Online Reactivation

NCache reactivation can be performed in online mode when an internet connection is available on the server. The Reactivate parameter is used to reactivate your license. Just follow the steps below:

Open Windows PowerShell as an administrator.
Execute the following command, by specifying the license key and the Reactivate parameter.

Register-NCache -Reactivate -Key xxxxxxxx-xxxxxx-xxxxxxxx -Environment Production -Clients 10 -FirstName John -LastName Smith -Email john@yourdomain.com -Company your_company_name

On successful reactivation of your license, you are prompted with a success message.

Offline Reactivation

NCache license can be reactivated in offline mode when an internet connection is not available on the server by specifying the OfflineActivate parameter. Just follow the steps below:

Open Windows PowerShell as an administrator.
Execute the following command to generate your Activation Request Code URL by providing the license key, and specifying Reactivate and OfflineActivate parameters.

Register-NCache -Reactivate -Key xxxxxxxx-xxxxxx-xxxxxxxx -Environment Production -Clients 10 -FirstName John -LastName Smith -Email john@yourdomain.com -Company your_company_name -OfflineActivate

You will be prompted with a long encrypted text on the screen. This is the Activation Request Code URL.
Copy this URL from the screen to another machine that has Internet access. It will open Activation Data Verification page.
Once you have verified that the information is correct, click on the Activate! button at the bottom of the page.
This will redirect you to Activation Result page showing the Activation Authorization Code.
Copy the Activation Authorization Code back to this machine and execute the following command in PowerShell by specifying Activation Authorization Code against AuthCode parameter.

Register-NCache -AuthCode <Activation Authorization Code> -OfflineActivate

On successful reactivation, you are prompted with a success message.
