Changing the Service Connection Model

When you use the ServiceConnectionModel attribute to change the connection model for a service, the OpenAccess SDK service sometimes reports multiple internal errors. When you examine the OpenAccess SDK packet log, you see the following messages:

Wed May 15 10:39:45 2014:Internal error, error detected in the event processor.
Wed May 15 10:39:45 2014:OpenAccess Common Library.SWANDM_Entity_FindFirstKeyValue.3820().21.The specified attribute does not exist.
Wed May 15 10:39:45 2014:OpenAccess Common Library.SWANDM_Entity_FindFirstKeyValue.3820().21.The specified attribute does not exist.

Wed May 15 10:39:45 2014:Internal error, error detected in the event processor.
...

To avoid internal errors when changing the connection model, perform the following steps:

1. Make sure the services have the ServiceConnectionModel attribute set to the value you want.
2. Delete both the Monitoring profile and Event trace profile of the services that have changed.
3. Create new Monitoring and Event trace profiles.
4. Stop all OpenAccess SDK services.
5. Stop the Agent.
6. Restart the Agent.
7. Restart all OpenAccess SDK services.
