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 9.x

Policy Manager 9.x

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.
