Virtual machine Deployment Metrics A workaround for a ora-27101 error on the server side of the rapid development platform

one of the most recent database errors in deploying a system with Hyper-V virtual machines is as follows:
1. Stop the Hyper-V of an existing server environment and copy the VHD file .
2, create a new virtual machine, select the files to be copied out
3. Start a new virtual machine, change the computer name of the virtual machine, and modify the monitoring and service name of the Oracle database.
4. Restart the Oracle instance and listen.
5, connect to the database, found to report the following error:
Error:
ora-01034:oracle Not available
ora-27101:shared Memory Realm dose NOT exists

The first feeling is that there is a problem with shared memory, there are many cases of online ora-27101 error codes, which are caused by different situations. This is due to a database not being started properly.
We just need to restart with a script.
