Before you apply the hotfix, you must stop some PowerExchange and PowerCenter tasks.
If you use PowerExchange bulk data movement only, stop the following tasks:
All PowerCenter workflows that extract data from or write data to PowerExchange
All PowerExchange Listener address spaces
If you use PowerExchange CDC, stop the following tasks:
All PowerCenter workflows that extract data from or write data to PowerExchange
All PowerExchange Listener address spaces
All ECCR address spaces
All PowerExchange Condense address spaces
All PowerExchange Logger for z/OS address spaces
All PowerExchange Agent address spaces
If you do not plan to update the PowerExchange libraries right away, you can postpone this step until right before you back up and update the PowerExchange libraries in steps 6 and 7.
