There are only two execution options available and those are listed at the bottom of the Scripting/Execution Options tab:

• Continue execution upon error. By default, if possible, the IDERA Schema Compare for Oracle Database attempts to continue the execution of the synchronization script upon encountering an error.
• Log script execution. By default, an execution log is created and stored at the location defined in the application settings. If the execution fails, you may consult the log for the error details.
