How to switch flexlm license model from single host to redundant servers

[D__E__Shaw_And_Co_]

Currently, we are using a single host as flexlm license manager host. We would like to have redundant license host servers.

I went through the flexlm user guide to understand the requirements. As per my understanding, we need to do below steps for the migration of licenses to redundant model:

1. We need to register three unique hosts/hostid’s  on https://registrationcenter.intel.com site.
2. Once we submit, a single new license file will be generated having details of all three hosts
3. We need to start the flexlm license server on these 3 hosts with the license file generated in Step 2.

Could you please add if anything else is required?

Few queries:

• Currently, in the client configurations, we are using a CNAME pointing to the single host.

Below is the client license file:

SERVER intel-licensehost-cname ANY 28518
USE_SERVER

Do we need to add all the servers in the client file (as below)?

SERVER intel-licensehost-cname1 ANY 28518
SERVER intel-licensehost-cname2 ANY 28518
SERVER intel-licensehost-cname3 ANY 28518
USE_SERVER

•  Once I have clarity on query 1, I would check if any downtime would be required for the activity.

Hello,

Please refer to this article on setting up redundant servers:

Yes, you will need to generate a license with correct Host names and HostIDs:

Please let me know if the above helps.

Could you confirm on the client file content?

Currently, in the client configurations, we are using a CNAME pointing to the single host.

Below is our client license file:

SERVER intel-licensehost-cname ANY 28518
USE_SERVER

Do we need to add all the servers in the client file (as below)?

SERVER intel-licensehost-cname1 ANY 28518
SERVER intel-licensehost-cname2 ANY 28518
SERVER intel-licensehost-cname3 ANY 28518
USE_SERVER

Hello,

Yes all 3 server names need to be added. This can be done in Intel Registration Center.
