Overview
In failover (Primary–Secondary) deployments of the APM Plugin, license exceed or license validation
issues may occur in the secondary APM Plugin server after a switchover.
This typically happens when the license file is not properly applied across all secondary APM Plugin servers.
Observed Behavior
- License exceed error displayed in APM Plugin
- Monitoring stops after failover
- Features become restricted due to license validation failure
- Mismatch in license usage between Primary and Secondary servers
Cause
Note: License validation is performed locally on each APM Plugin server.
If the AdventNetLicense.xml file in the Secondary server is:
- Missing
- Outdated
- Different from the Primary server
License-related errors may occur during or after failover.
Resolution Steps
Primary Method: Apply License via UI (Recommended)
Recommended: Apply the same license used in the Primary server directly through the Secondary APM Plugin UI.
- Login to the Secondary APM Plugin server UI.
- Click on Apply License (Refer sample screenshot below).
- Upload the license file present in the Primary server ( <OPM_Home>/AppManager/working/classes/AdventNetLicense.xml ).

Alternate Method: Manual License File Replacement
If applying the license via UI is not feasible, follow the manual method below:
- Copy <OPM_Home>/AppManager/working/classes/AdventNetLicense.xml from the Primary server.
- Replace it in the same location on the Secondary server (<OPM_Home>/AppManager/working/classes/ ).
- Restart the OPM service on the Secondary server.
Note:
- If the file
<OPM_Home>/AppManager/working/classes/ApmPlugin_AdventNetLicense.xml is present on the Primary server, please copy it as well and replace it in the same location on the Secondary server.
Warning: If the license file is not consistent across servers,
license exceed errors may recur after switchover.
- Ensure license file consistency across all APM Plugin servers.
- If the issue persists, contact support and share the latest APM Support Information File (SIF).
