Environment

Release : 9.4

Component : API GATEWAY

Cause

It looks like the gateway was trying to load a WSDL in cache from a host that was not reachable. 

Resolution

We were able to fix this by disabling the services that had an issue directly within the database.

1.  We have listed all of the services with the issue by executing the following: 

mysql ssg -e "select * from  published_service  where wsdl_xml like'%Service..svc?wsdl%';"


2. To disable services with the issue:

mysql ssg -e "update published_service set disabled='1' where wsdl_xml like'%Service..svc?wsdl%';"


3. and restarted the ssg service

SSG Service is now running and we are able to login to the gateway. 

4. to enable those services back,  make sure that gateway can reach out to the host. 

Then run this:

mysql ssg -e "update published_service set disabled='0' where wsdl_xml like'%Service..svc?wsdll%';"


service ssg restart
