please extract 10 keywords and their respective score based on importance from the paragraph and sort the result by score, only print keywords and score, without other words,print format is keyword:score, the paragraph is : If a force reroute fails, you can get an error like:
SQL ERROR  :
  SQLCODE  : -10731
  SQLSTATE :
  MESSAGE  : Client failed to reroute after a server change in workload class routing: Invalid routing location or failed to create internal statement routing connection

Improve the error so there is a more specific reason, for example:
- Statement routing was implicity disabled, probably due to bad topology or port routing
- Statement routing is disabled
- Failed to create internal statement routing connection
- Invalid routing location

This will make force reroute failures easier to diagnose. Make sure your entire response is wrapped in JSON format.
