Unable to Sync application with CA Developer Portal 4.5

Products

• CA API Gateway
• CA API Developer Portal

Issue/Introduction

On portal UI, it shows sync successfully, but the new created application is not really sync to the gateway, and the gateway log shows following error message: 

Unable to obtain HTTP response from https://xxxxxxxxxxxx:9443/sync/v1/applications?identifier=xxxxxxx: Received fatal alert: internal_error 

 

 

 

Environment

Release : 9.4

Component : API GATEWAY

Cause

Dump pssg log on portal server:

docker service logs portal_pssg > pssg.log 2>&1

 

Search in pssg.log with the complete uri in the gateway error message, compare the timestamp in pssg.log and in the gateway log, you would see the pssg finish the sync task after the failure on gateway server. That's why it shows sync successfully on portal side, but the application data is not really sync to the gateway.

 

It indicates the portal is too slow to finish the sync task in time.

Resolution

option 1: improve the portal performance

option 2: increase the interval for the portal sync application schedule task, and increase the read timeout of the route assertions in the scheduled task policy

Note that there are 2 route assertions in the policy, so we might evaluate the time as below,

task process time = timestamp of sync finish in pssg log - timestamp of failure in ssg log + current read timeout of the route assertion

then we could set the read timeout of each route assertion as,

read timeout = task process time + 1 minute

And set the interval of portal sync application schedule task as,

task interval = (read timeout) * 2 + 2 minutes

 

If the error message occurs again, repeat above
