To be improved

Script to be improved , Just completed the time-consuming recovery part , It can be improved later , For example, if the path of the online log is inconsistent with the production, you need to change the path , After the change, it still needs to be done alter database open resetlogs;
Some also need to rename the database , These can be realized by automatic script .
