We have the following environment:
AEP 7.2.3
Windows Tomcat 8.5.66
AOD 7.2.1

We have configured AEP variables in our AOD application. However, the IVR application is unable to pick the values set from AEP web page.

This is what we see in our Application trace:

Ideally, what we should see is the following (this is a good call scenario of the same application from a different AEP and Application server):

22/07/2021 14:03:23:627 DEBUG - DF28110F05FC3BA83E5F92D4609CA6ED:/xxx: AdminVarCache:init: load data from the Experience Portal platform

Is this any known issue with AEP 7.2.3 platform? Or anything to do with our AOD application? Or with our Windows Application server?

I am unable to get any clue because same application picks up AEP variables values successfully from other setup of AEP - Tomcat environment.

The environment where it works fine is exactly the same:
AEP 7.2.3
Tomcat 8.5.43
AOD 7.2.1

This is preventing us to use dynamic values for the AEP variables.

Appreciate any inputs on this regard,

Thanks for your support.

Im passing for the same problem,

I would contact avaya EPM support to help you, its a possible enviroment problem. Thats why the bold file returns null.

Have you ever tried it?

Hugs.

There must be an error in the vpapplogclient.log (somewhere in the app server directory). Typically, restarting the EPM web service would help

Thanks a lot for your quick responses. I will share the final feedback / actions performed to resolve this issue.

Hi Wilson,

vpapplogclient shows the following message:


2021-08-02 07:43:53,907 818530 [VPAlarmMonitorThread: https://10.xxx.x.xx/axis2/services/VPAppLogService] ERROR - AlarmMonitorThread:EPMWebServicesClientBaseImpl:logAlarmsAxis2() - Caught Exception FAILED with AxisFault faultCode: null error: Connection timed out: connect to log entry size: 1 to URL: https://10.xxx.x.xx/axis2/services/VPAppLogService from AE server: CIBLVPxxxxxx002 First SID: cpd1-i1-mpp1-2021214063213-1 Last SID: cpd1-i1-mpp1-2021214063213-1 NOTE: It could be caused by this EPM is not online or some other network issues.


We have already performed an EPM reboot and yet the AEP variables values are not picked up by the application.

Is there any other workaround or action needs to be taken to resolve this issue?

Appreciate any further inputs on this regard,

Thanks for your support.

Warm regards,
Jaydeep Hatekar

This error seems to indicate there is a connection problem between the app server and EPM.

Ok fine, thanks Wilson for sharing this perspective.

I will re-check the connectivity between EPM and App server and share the feedback.
