D Identifying the Jobs That Will Not Run in Enterprise Manager for 2-System Upgrade Approach

This appendix describes how you can identify the jobs that will not run in the existing Enterprise Manager system and in the upgraded Enterprise Manager system.

D.1 Identifying the Jobs That Will Not Run in the New, Upgraded Enterprise Manager System

The following SQL query will help identify any jobs that are currently blocked from running if only certain Oracle Management Agents for their targets are migrated. Run the query in Enterprise Manager Cloud Control.At the end of the query, is an optional query for modifications that can be used to give a list of Oracle Management Agents that need to be migrated.

For more information on the need for identifying jobs that will not run in the upgraded or new Enterprise Manager System, refer to Chapter 3, "Things to Know"
