Hi

May I know what is the benefits of using the License Servers option and when to use it? Read through the documentation http://localhost:57772/csp/docbook/DocBook.UI.Page.cls?KEY=GSA_license#G... but failed to comprehend it.

Thanks

Regards
Jimmy

Try this.

1. Stop caché.

2. In cache.cpf write correct remote license server

[LicenseServers]
LOCAL=host,port

where port usually is 4001

3. Start instance

Instance should start and show correct license information.

The benefits are:

You only need one license key for many servers
Server can consume however much licenses it needs, up to a specified max limit.

Use it for multiserver deployments.

Hi Eduard

But for it to work, the Cache instance will need to have a license key in each server before the License Server to actually work. If without a cache.key, it will not work..Tested using "d $SYSTEM.OBJ.ShowServer()" command. Unless I test it wrongly.

I have update the cpf file with the following info (removed the cache.key file from my local cache instance)

[LicenseServers]
SERVER 4=7.7.7.4,4001

Getting "Licensed to: License missing or unreadable. " in SMP. Tried to run the following in Cache instance..

USER>Do $System.License.ShowServer()

Not connected to license server

Next I shutdown Cache, put back the cache.key into my local instance and start. Then run the command again :

USER>d $SYSTEM.License.ShowServer()

Active license server at address = 7.7.7.4 port = 4001
USER>

In the documentation it also mentioned quote " However, each Caché instance must have a local copy of the authorizing license key file installed " taken from https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY...
