Alachisoft NCache 4.1 - Online Documentation

Evaluation Period Expiration & Extension

By default, when you install NCache Client, it is installed as a "Fully working Evaluation Copy" and is valid for 60 days. At the end of the evaluation period, NCache will stop working.
Indications of NCache Being Expired:
You will be able to notice that NCache evaluation period has expired from the following places:
  • NCache API will no longer work. You won't be able to add items to the cache or fetch them.
  • NCache License can be verified by running verifyncachelicense tool. (Path: /user/local/ncache/tools/ )
Extending Evaluation Period:
If any of the above happens, then it is time for you to either purchase NCache license or extend the trial period for further evaluation. You can obtain an "Extension Key" from Alachisoft Sales. Please send an email to (or to your account manager if you're already in touch with him/her) and ask for an extension key. You will be provided a 30-day extension key.
Once you have the extension key, run the NCActivate program by using either shell script present in bin directory of Java client installation directory:
[root@...]# bash (Path: /user/local/ncache/bin/ )
[root@...]# java -jar NCActivate.jar
if your class paths are not configured then
[root@...]# java -cp [Java client installation path]/lib: [Java client installation path]/NCActivate.jar com.alachisoft.ncache.nactivate.ui.Main
Note: [Java client installation path] by default is /usr/local/ncache
You will see following screen on desktop. Please select "Extend evaluation period" option and then click Next button.
Once you click Next button, you will see the screen shown below. Please enter the extension key provided to you by Alachisoft Sales and then press Finish button. If this key is valid, you will be prompted with a Success message. If the key is not valid, you will be prompted accordingly.
Note: A 30-day extension is valid from the original installation date, not from the day you try to extend. So, if you have been waiting for 15 extra days after the initial 60 day evaluation period to extend it, you'll only get 15 extra days extension.
