If you are getting “Zero Downtime Mode is Not Running” message while middle of your operation then you can check the following solution…
I have got this message screen while “EHP7 Stack 10″ upgrade operation was working…
Then we should check the following steps ;
- Log on to the shadow system
- call transaction CRR_CONTROL
- check the replication state
Shadow system’s CRR_CONTROL output ;
We have to “Start Transfer” before continue to our process.
For this ;
Control –> Start Transfer
Now we should see the status GREEN like below
Now we can try again with the option “Check Status Again”
And i hope that you will get the following “completed” screen for the related phase.
