Oxygen XML Forum

Hello, we have setup a license server and oxygen sdk on AWS. Somehow whenever we load the page oxygen keeps connecting to license server every min. Here is the call log. How can we make oxygen connect to license server only once and not repeatedly.

Hello,

Oxygen Web Author connect to license server every about 90s as part of the license usage custom protocol. This proprietary license usage protocol is not configurable.

Does this behavior cause any issues in your usage of the Web Author with the License Server?

Best Regards,
Michael

Hello Micheal,

We are utilizing more licenses instead of the same license being sent every 60 seconds and at one point we run out of licenses and the server starts sending 502 error.

How can we avoid this?

Thank you,
Akshat

Replying for the updates.

Hello,

The license consumption issue is not cause by the license-use keep alive periodical request. Those requests ensure only the active users consume a floating license and frees consumed license for any users that are no longer being active.

In your case the license consumption most likely is caused by a misconfiguration on the load balancer (API-gateway / reverse-proxy) that interferes with the cookies the Web Author instance uses to track a user session and consume a license for it - this could have multiple side-effects on the editing experience and loss of data in most cases.
When deployed behind a load balancer you should configure your load-balancer with sticky sessions (if you have multiple Web Author instances) and stop if from altering the cookie values as most load balancers append prefixes or suffixes to the cookies passing trough them.

For the Web Author to function as expected its cookies should not be tempered with.

You can read more in the Setting up a Load-Balanced Server [1] topic from our user manual.

Best Regards,
Michael
