Problem
DP 8.x and 9.x, when using Restart Failed Objects in the DP GUI, it fails "Invalid Message Format".
Workaround
Use the cli workaround… omnib -restart <sessionID>
eg. omnib -restart 2015/11/04-3
Solution
Edit the global file, and add
UseJCEForRestartResume=0
Close the GUI, Open the GUI
Try “Restart Failed Objects”
Note A: this variable is not documented within the file text.
Note B: The global file default location
/etc/opt/omni/server/options/global - Unix Cell Manager \ProgramData\OmniBack\Config\Server\Options\global - Windows 2008 or later CM
