Oracle Solution for Error ora-31405

ORA-31405: cannot make changes while change set string is advancing

What triggered the Error:

The change set is currently advancing. Change sources related to an advancing change set cannot be altered. Change tables related to the advancing change set cannot be created, altered or dropped. Some or all the parameters of the change set cannot be altered while the set is advancing.

What should we do to fix it:

Wait until the change set has finished advancing, then reissue the command. If altering the change set, only the advance_enable parameter can be altered during an advance.
