API Gateway: Connection to the Gateway has been broken

Products

• CA API Gateway

Issue/Introduction

When logging in to Policy Manager, the below error occurrs:
 

"Connection to the Gateway has been broken."

Environment

API Gateway 10.x

Policy Manager 10.x

Resolution

1. On your CA API Gateway, the size of the log file ‘ssg_0_0.log’ may become very large which could prevent successful Policy Manager logins.
   • Deleting the file and restarting the CA API Gateway may be a way of remediating this issue if the root cause is a large ssg_0_0.log file.
2. Also, possible approach:
   • Adding the connection property setting of sendStringParametersAsUnicode = false on the jbdc connection the performance could improved greatly.  If the connection is trying to call with nvarchar vs. varchar and that was forcing a conversion to happen on the db which is why the response times could be slow.
